how-aircraft-engines-work
Aircraft engines and car engines seem like they would be rather similar. After all, they are both machinery that power massive vehicles used to transport people and goods. But, the truth is, aircraft engines are rather different. Aircraft utilize RPMs, not multi-gear transmissions.

RPMs are like gears in a car, in the sense that propeller driven aircraft depend on specific RPM, or revolutions per minute, settings to achieve different stages of flight. So, the RPMs are at maximum setting during take-offs and landing, and they are reduced to a slower and more efficient setting during flight. During flight, the aircraft engine’s RPM doesn’t change, but the engine power, which translates to speed, can.
 
Aircraft engines have three major controls: the throttle, the propeller knob and the mixture knob. While the throttle is like the gas pedal of a car in terms of increasing and decreasing power, it’s different in that the aircraft engine still runs at the same speed even as the throttle changes the power output. That’s because the propeller knob changes the RPMs. When the aircraft takes-off, the propeller knob and the throttle are set to full forward for maximum power. But at cruising altitude, the throttle is set to reduce the power output and the propeller RPMs accordingly. The mixture knob is then used to lean the fuel-air ratio to the proper stoichiometric ratio for that particular altitude so that the aircraft flies smoothly.
 
Notice, to reach cruising speeds, only the throttle and the mixture knobs need to be changed. But the aircraft can still speed up or slow down. The propeller knob doesn’t have to move, and the RPMs don’t have to change. That’s because speed is based on the power output by the throttle, and how propeller blades automatically change pitch, or the distance it would move forward if it were cutting through a solid, accordingly.
 
Clearly, aircraft engines and car engines are not that similar or comparable. You don’t have to deal with altitudes, stoichiometry of fuel-air ratios, or pitch when you drive a car. But, like a car, you do have to maintain your engine and repair and replace parts when need-be. At times like that, you have ASAP Purchasing, owned and operated by ASAP Semiconductor, one of the premier suppliers of aviation parts and components ranging from massive engines to tiny bearings.

autonomous-vehicles-on-the-rise
Autonomous cars are self-driving vehicles. It is very interesting to see how long we have come from having a basic mode of transportation which has slowly but surely evolved into much more than that. A handful of the automobile industry has slowly transitioned into building their first autonomous cars. Companies such as Mercedes-Benz, Cadillac, Audi, and of course Tesla electric have many of them on the road today. However, owing to the nature of the advancement there are still many errors to fix due to possibilities of crashes and potential deaths as seen by Tesla Model S as the first autonomous car fatality. It is important these vehicles can detect objects, fog, and all the hazards of the road 100% of the time before progressing any further.
Autonomous vehicles need Infrared cameras to allow better visibility than light-based cameras. Although there is a limitation due to the high cost and limited resources available. Now the time has gone into research to find a different solution that will enable an overall better technology for the vehicle.
The University of Southern California, University of Wisconsin, the Air Force Research Lab and the University of Missouri collaborated to create a new material that enables better-infrared technology. This new material is called chalcogenide perovskites. This was found in barium titanium sulfide (BTS) which cooperated uniquely, where the light interacted in two different directions. The BTS would make for better image contrast which well helps better improve sensing objects. This new technology will improve and advance the technology behind autonomous vehicles efficiently at a better cost.

Toshiba has just announced they are adding two brand new N-Channel devices to their extensive family of U-MOS IX-H family of high-efficiency and high speed switching MOSFETs. TK3R1E04PL and TK3R1A04PL are the two newest additions to the MOSFETs lineup by Toshiba. They help designers improve performance while reducing power consumption in most of the power supply applications for DC-DC converters as well as the secondary side circuits of the SMPS AC-DC power supplies. They have a maximum VDSS rating of 40V and allows for operation with gate-source voltages of +/-20V and the maximum respective drain currents are between 100A and 82A. Having low typical on resistance of just 2.5mO at VGS=10V enables an output capacitance (COSS) of 1000pF which ultimately ensures the efficiency of the on-state operations, rapid switching and lowers switching losses.

TK3R1E04PL and TK3R1A04PL provides the optimal trade-off between resistance and capacitance to support optimum performance and efficiency in power supply applications. Boasting a synchronous rectification designs with low output charge that reduces the rectification power loss in regards to device contributions. Lastly the TK3R1E04PL and TK3R1A04PL will primarily operate with channel temperatures up to 175 degrees Celsius thanks to the U-MOS IX-H technology devoted to ensuring stable operations over a variety of load conditions and temperature ranges.

Recently, On-chip tuning capacitors have had a major issue with being too lossy and causing problems for the user. This issue has been identified and according to the university of California, Santa Barbara has allegedly stated the issue is within the,

"deposition of complex oxides, such as barium strontium titanate, is problematic because of the high temperatures and oxygen-rich environment involved."

Also reporting another major issue has to do with the BST- based device being limited by the deposition and processing methods appose to the actual base material. A change in fabric has become a main solution to their overloading issue by replacing chemicals commonly used in photolithography that contaminate BST. The film in the chip requires a smaller electrode dimensions and finer lithography that the standard integrated capacitor structures. Another challenge that that they face is low-loss reactive devices are microwave frequencies.

Finding alternatives is their main concern to cease the unruly effects that the chip has been encountering. Over much research they have soon discovered that the deposition of low dielectric loss is possible from a hybrid,

“hybrid form of molecular beam epitaxy that uses metal organic precursors.”

As the BST capacitor have many uses they have soon to be used to create phase shifters for phased array antennas in mobile communications or also may be used in antennas in cellular communications.

Despite these unruly materials with the BST this is not the first dilemma of its type. According to Professor Robert York of UCSB there has already been,

"some barium strontium titanate devices are already used for commercial RF electronics, and the infrastructure for deposition and fabrication already exists within semiconductor foundries.”

As a result, the University to provide ICs with films that are placed exactly on metal electrodes.

In recent News, Apple the creator of the iPhone and many apple products have finally witnessed a drop-in sales in its birth place of China. Many competitors are on the rise to surpass and beat apple sales, Samsung and Android being some of the top. Per the tar Worldpanel Comtech Iphones take 31.8% of smartphone sales with a growth of 1.3%. Android a top apple competitor has taken a plunge in the US numbers with 66% and a total of 0.6% decline in revenue sales. The release of the IPhone 6s allowed Apple to compete with Samsung’s release the Galaxy S7/S7 edge. In the US both companies competed side by side for the number one spot was recorded as the,” iPhone 6s devices accounted for 15.1% of the US smartphone OS market in Q2 while Samsung’s Galaxy S7/S7 edge accounted for 14.1%.

“Alongside the US the numbers in the UK headed in the same direction showing that.”

Apple grew 3.1% to 37.2% market share, in France it took 20.2% share and in Germany its share went up 1% to 14.2% share.” Although these sales in the US and UK have gone up it has not been the same for China. Some say that the plunge was due to market share loss or even the being,” outmaneuvered and outclassed.”As iphones are released almost every year many state that they are lacking newer features rather than just an average software upgrade with a better camera. These numbers that were lost due to these factors are quite a large impact in the company. Tim Cook the CEO of apple tries to explain their downfall and says, “we had a surge of upgraders that came into the market for the iPhone 6 or iPhone 6 Plus, and the upgrade rate increased relatively more in Greater China than elsewhere around the world.”
