Sennheiser’s PC 373D Dolby 7.1 Gaming Headphones

Sennheiser has not made any adjustments to the basic concept on the PC 373D Dolby 7.1 gaming headphones while comparing with its successful predecessor. The gaming headset, like its predecessor, can be connected to the PC via USB or mini USB and is based on an open design for good ventilation of the ears.

The design of the PC 373D Dolby 7.1 gaming headphones has been slightly revised compared to its predecessor. While the PC 363D was completely black, the successor has additional, discreet red elements. There are small red lines on the microphone bracket and the cable. The inside of the auricle was also lifted in color.

Overall, however, Sennheiser continues to rely on the familiar, simple, functional design. The processing is high-quality and the carrying comfort was increased.

Great Package of Delivery


The PC 373D Dolby 7.1 gaming headphones is delivered with manageable accessories. In addition to the headset, the scope of supply includes a 1.2 m long extension cable so that the cable length can be extended to a total of three meters. In addition, there is a USB surround dongle in the package, which can be switched between stereo and surround sound quickly.

The specifications of the PC 373D Dolby 7.1 gaming headphones are as follows:

Transducer principle: Dynamic, open

Frequency range: 15 Hz - 28,000 Hz

Impedance: 50 Ohm

With these specifications, the headset is also compatible with all other players, such as MP3 players and mobile phones.

Sound Quality

The goal of Sennheiser is to produce headsets with a sound that satisfies both professionals and ambitious amateur gamers. This is the absolute success of the manufacturer with the PC 373D Dolby 7.1 gaming headphones. The Sennheiser PC 373D Dolby 7.1 gaming headphones delivers 7.1. Dolby Surround Gaming Sound of the top class.

The sound is clear and the gaming headset manages to reproduce basses as well as letting higher notes sound naturally. The highs and lows also have a very good correlation with each other.

The 7.1 surround sound in PC 373D Dolby 7.1 gaming headphones is characterized by a realistic and precise spatial sound. One has the feeling exactly to determine, where the sound in the game comes from.

Sennheiser has developed a new software for the PC 373D Dolby 7.1 gaming headphones to precisely adjust the surround sound for every gamer's ear. The software implementation is intuitive and allows gamers to choose between four different equalizer settings.

Microphone

The new Sennheiser PC 373D Dolby 7.1 gaming headphones headset is also equipped with noise canceling. In this way, background noise is avoided, thus ensuring that only your voice is recorded. The voice is clearly transmitted.

There is also the possibility to use the "Mic Sidetone" on the headphones and the Sennheiser software to adjust the voice reproduction. This makes the voice recording even clearer.

Of course, the PC 373D Dolby 7.1 gaming headphones also has the simple, intuitive mute of the microphone, which we know from the PC 363D. The microphone is muted when the microphone is raised until a "soft" sound is heard. A small but very useful feature.

Overall, the implementation of the microphone is impressive all along the line and is in no way inferior to the sound quality.

Comfort

Besides the sound quality, Sennheiser has always attached great importance to the wearing comfort of the headset.

The auricles are covered with velvet. This makes the headset very soft and comfortable to wear. Sennheisser himself applies the ear pads as an "XXL ear pad".

With a weight of 354 grams, the headset is not a light weight. Due to the very soft padding of the temples, this weight is not noticeable even during long gaming sessions when worn.

Overall, the Sennheiser PC 373D Dolby 7.1 gaming headphones is also convincing in terms of style and comfort.

DirectReality of Microsoft - New VR Interface Planned for Windows

Since Microsoft has presented projects such as HoloLens, the company is the pioneer in innovation for many people. Now Microsoft has once again secured more rights to something new called

Although Microsoft recently assured that VR is not shown during this year's E3 during the own briefing, the company only a few days earlier secured the rights to something called DirectReality.

Sounds exciting and many people will now say that it has nothing to do with gaming, but you are wrong. DirectReality is said to have a direct reference to gaming. Microsoft has just registered a new brand name just a few days ago, which points to a new interface for Windows and perhaps also the Xbox One Scorpio. What exactly lies behind DirectReality hides this year's E3 probably not give up.

Microsoft applied for trademark protection for the term "DirectReality" on June 2, 2017 in the United States and applied for computer software, computer games, software for holographic apps and their online versions. However, the US Patent and Trademark Office (USPTO) does not provide more detailed information. Companies such as Microsoft also often secure brand names, which are ultimately not used.

 

DirectX, Direct3D - DirectReality?


However, in the context of the forthcoming E3 games fair and the presentation of the Xbox One Scorpio, the brand DirectReality ensures some speculation. Microsoft has been using the term "Direct" for important interfaces for the Windows operating system, for example DirectX, Direct3D or DirectShow. Even the Xbox owes its name to DirectX, since it was originally planned as a DirectX box. This could be a new graphics interface for DirectReality that is related to the mixed reality features that Microsoft is planning for Windows 10 and in Hololens.

Perhaps a standard for VR / AR under Windows


However, it would also be conceivable that Microsoft, like DirectX for 3D graphics under Windows, is planning a new standard for virtual and augmented reality in Windows 10, which allows the development of software for hardware from many different manufacturers.

A standard would probably also be very useful for developers who want to offer their VR software for consoles like the Xbox One, Scorpio and Windows 10. There may be some information at E3 during the Microsoft press conference. Microsoft has a lot to tell and in the person of Phil Spencer already warned that this time 90 minutes will not be enough.

The Microsoft could be a feature with regard to the HoloLens, but of course also the Scorpio, which supports VR headsets, possibly also the Hololens. In addition to Virtual Reality, Augmented Reality and Mixed Reality, DirectReality would be a new form and could even be a reference to a controller unit. With a little luck, we know more about the E3, otherwise it could be a long-term project, so we could only learn about it in the distant future.

Novel Innovation Could Allow Bullets to Disintegrate After Designated Distance

Purdue University – Bullet to Be Non-Lethal

Presently bullets have been made from various materials particular for the projected application which tends to retain an important portion of their energy after travelling hundreds or thousands of meters. This could result in unwanted significances like unintended death or injury of those around the place as well as security damage if the target was missed.

Very often stray bullet shootings are overlooked consequence of firing which could result in severe injury or even death to bystanders or collateral damage victims in the military. Hence a need in law enforcement, military together with civilian segments for a safer bullet would considerably decrease collateral damage as well as injury.

Technology has been created that could avoid these occurrences at Purdue University. Research group headed by a professor of materials engineering and electrical and computer engineering, Ernesto Marinero has designed novel materials and fabrication which enables a bullet to be non-lethal which collapses after a selected distance.

This technology was the consequence of a need for safer bullet which would considerably decrease security damage as well an injury in law enforcement, civilian and military segments. Conservative bullet tends to have a substantial percentage of their energy after travelling a hundreds or even thousands of meters.

Combination of Stopping Power of Standard Bullets/Restriction of Range

The newly developed Purdue innovation helps the bullet to break over a predetermined period owing to the heat that is generated at the time of firing in combination with air drag together with an internal heating component. The heat conducts over the complete bullet part, melting the low temperature binder material facing drag forces that tends to result in breakdown.

The technology is said to be a combination of stopping power of standard bullets, the shrapnel-eliminating aids of frangible bullets together with a restriction of range in decreasing injury or death of would-be spectators. The Office of Technology Commercialization of Purdue Research Foundation has patented the technology and is said to be available for license. The researchers at Purdue University had established materials together with fabrication for ammunition which became non-lethal after a chosen space.

A professor of emergency medicine and director of the Violence Prevention Research Program at UC Davis School of Medicine and Medical Centre, Garen Wintemute had commented that `stray bullet shootings gave rise to fear and insecurity among the people. They tend to remain indoors and stop their children from playing out in the open thereby changing their pattern of their daily routine to evade from being struck by a bullet intended for someone in mind.

No Research – Exploring Epidemiology of Firings

However, no research had been done at the national level in exploring the epidemiology of these firings and such information is essential in identifying preventive measures’. He further added that stray bullet firings are mostly a side effect of planned violence what is indirectly known as collateral damage.

Those who tend to get shot have little or no warning; opportunities to indulge in preventive measures once the shooting tends to take are restricted. We will only be capable of preventing these shootings to the extent that we are able to prevent firearm violence unless we intend to bulletproof the complete communities together with the residents.

Millimeter-Wave Technology: Highly Sensitive Tracking Nose in Space

Millimeter-Wave Technology

Low Power Millimeter-Wave Amplifier

It was recently announced by Hiroshima University and Mie Fujitsu Semiconductor Limited – MIFS, the development of a low power millimetre wave amplifier which tends to feed on 0.5 V power supply, covering the frequency range from 80 GHz to 106 GHz. It had been invented utilising Deeply Depleted Channel – DDC technology of MIFS and is the first W-band amplifier (75-110GHz) which operates with low power supply voltage.

 Technology details will be presented at the IEEE Radio Frequency Integrated Circuits Symposium – RFIC 2016 which was from June 4th to 6th in Honolulu, Hawaii. The W-band is said to cover frequencies utilised by automotive radars. Radars with millimetre-wave beam would be essential for sophisticated driver-assistance and self-driving to scan capability which can `see’ in day as well as night conditions as well as in adverse weather situations.

 This type of phased array would comprise of up to hundreds of transmitters and receivers. Since battery-powered cars tend to be more common, it is vital that these circuits have a tendency to be low power and lowering the power-supply voltage seems to be the most effective means of achieving the same. But transistor performance tends to fall with voltage and W-band amplifier has not operated so far as low as 0.5 V.

High-Performance Silicon MOS Transistors

A W-band amplifier at 0.5 V had been successfully demonstrated by the team of researchers by bringing together DDC technology of MIFS and design techniques created by Hiroshima University. The DDC technology provides high-performance silicon MOS transistors also at low voltages and is presently made available as a 55-nm CMOS process from MIFS.

 Moreover, the design techniques tend to enhance transistor as well as circuit performance at millimetre-wave regularities. A graduate School of Advance Sciences of Matter, Hiroshima University, Professor Minoru Fijishima had commented that `now seriously low power W-band circuits really seem possible, they would think about what can be done with them. Applications aren’t restricted to automotive radars and high-speed communication between base stations.

 What if one had radar on their smartphone? Presently smartphones tend to sense things already such as acceleration, audible sound, and visible light together with the magnetic field of the Earth. However the only active searching device is that tiny LED – light emitting diode, which can brighten at best a few meters.

W-Band Amplifier - Reliability

He further stated that by adding millimetre-wave radar on your smartphone, it does not have to be a imaginary main radar that tends to sense waves reflected back but your smartphone could respond to waves from the radar of your friend, sending some signals back to them.

 A new set of applications can be developed comprising of games. Professor Fujishima further added that another significance of our 0.5 V W-band amplifier is reliability and the researchers are aware that they are long lasting. They tend to degrade as one measure them, within days or hours and not years due to the supposed hot-carrier effects.

The 0.5 V supply voltage is said to reduce hot-carrier generation, considerably. In comparison to conventional SMOS the DDC transistors provide amazing performance in low-power processes. The research group intends to progress in exploring the possibility of low-voltage millimetre-wave CMOS circuits.

High Pressure Key to Lighter, Stronger Metal Alloys, Scientists Found 

metal
With the scientists and technicians creating a revolution, the world has witness some of the great changes. We are quite grateful that we are able to live a more peaceful and cosy life when compared to our earlier generations. However, the world has progressed in every field be it technology, medicine or even metallurgy. There are reports every day that amuse us and we are quite blessed to live in this era. Each day we come across some new kinds of discoveries and this has only got better with each passing day. Certainly, a change has shaped the world into a better place. Few weeks ago, a report was released which stated that if high pressure was allowed, then it could make the new and improvised versions of metal compounds which are can resist heat than the normal metal alloys. This theory of the conventional metal alloys was released by the researchers of the Stanford University

THE BLENDING OF METAL ALLOYS

It has been since ages that metallurgy has seen the blending of the metals in order to create improved and stable metal alloys. They used to have exclusive properties for the last hundreds of years. The previous theory included with one or two important metal comprising a higher portion of the mixture and the other elements are in less proportion.

They form a compact structure. Ever since the inception of the metallurgy, the scientists were successful in creating 2 structures till date. The third structure has taken a huge toll on the scientists as they have not been able to figure out still.

THE STUDY

The recent study which was published in the recent journal have reported that they were successful to come up with a new design of an alloy which comprised of normal metals. The structure is somewhat hexagonal in shape and it is closely packed. This type of similar structures has been created in the past but they used to contain a huge amount of harmful elements.

The elements were mostly alkaline metals or rare species of metals. They have been able to make the compact structure from the very common metals which are normally used in the engineering department.

THE PRESSURE APPLIED ON METAL ALLOYS

They have found that it is ultimately the pressure that helps in achieving all these. A new device kind of form has been used in order to achieve this. The device is used to confine the minute samples of the high entropy metal alloys to get pressurized to a high pressure normally as 55 Giga Pascals.

The pressure is so humongous that it can be seen when there is large meteorite crashed on the surface of the earth. The high pressure seems to break the interaction of the magnetic impact. The metal alloys still maintain the compact hexagonal structure even if the high pressure is taken off from them. So, we are grateful to the great renowned scientists.
