Typically the wireless charging module is made of a transmitting module and a receiving module, each of which has a control unit and an antenna. Up to now the miniaturization of electronic appliances has been confined to conventional antennas that are made of magnet wire coils with poor flexibility. To overcome this challenge Sumitomo Electric has developed a ultra-small wireless charging module where the magnet wire coils have been replaced by flexible printed circuits (FPCs) based on company’s knowhow in 3D wiring technology, first in the industry resulting in reduction in size of antennas will improving their flexibility. The new product is expected to be used in wearable devices, health-care devices as well as industrial equipment. The commercial production is scheduled on October 2014.

NTN has developed “WIND LAB” industry’s largest testing machine for wind turbine extra-large bearings for helping to improve technical development of main shaft bearings of offshore wind turbines. WIND LAB applies load to bearings in vertical and horizontal directions using six hydraulic cylinders to produce the conditions as if the wind turbines are used in, for conducting detailed technical analysis and specification testing of bearings. Testing can be performed under ordinary conditions, as well as load condition under extreme situations. The machine is compatible with different type of bearings such as spherical roller bearings or tapered roller bearings. The “WIND LAB” incorporates the condition monitoring system for wind turbines (CMS) known as “Wind Doctor” for monitoring bearing conditions during the testing.
Mitsubishi Heavy Industry has developed a 2 megawatt (MW) 16 cylinder high speed gas engine recording world’s highest power generation efficiency ratings in a high speed gas engine. The new engine has been developed based on two-stage turbocharging (where turbochargers are arranged in series in the low- and high-pressure stages where an intercooler is placed between them) and Miller cycle (where the profile of the valve cam is engineered in a way that the timing of the valve closing shifts so that the expansion ratio becomes greater than the compression ratio, a configuration which is aimed to improve thermal efficiency) technology. The new engine power generation efficiency exceeds 44%.
Here is a nifty little gadget by Toshiba designed for people weary of their day to day physical health and well-being. Toshiba’s WERAM1100 is a wearable wristband fitness tracker capable of estimating physical activities such as amount of step taken; distance travelled as well as amount of calories burned. The new device is also capable of measuring sleep states and patterns and hour of sleep per day. It comes with a software application helping it to sync-up the information to a smartphone via Bluetooth allowing its user to view gathered data as graphs. Furthermore, users can upload photos and calories counts of meals, to monitor diet along with physical activity and sleep. WERAM1100 has been designed based on Toshiba’s signal processing technology helping it with minimum power consumption. The new WERAM1100 comes in four vibrant colors black, light gray, smoky pink and blue green. IT comes with easy operation allowing users to program and log individual, everyday life activities. It comes with built-in vibrator which can be set to go off when pace counts, distance and other targets have been reached. It also comes with an alarm. Toshiba will launch cloud services for wearable products which would provide big data analytic via company’s state-of-art engine. The product comes with IPX5/IPX7 water/dust protection.
Murata has developed a ZRB Series of monolithic ceramic capacitors (MLCC) designed to reduce “squealing” noise which is typically induced by mechanical vibration of the capacitor. This type of noise is a concern for electronics industry which affects many types of consumer electronic devices such as laptop PCs, tablets as well as smartphones. Read more
Murata has recently released world’s smallest and lightest low powered SMD piezoelectric sounder suits for portable health care devices which includes such product as blood glucose meters, personal thermometers. The size and weight of the device has been reduced by 44% in comparison to previous Murata products. The new PKMCS0909E4000-R1 measures only 9x9x1.7mm and weighs only 160mg. Sound pressure level output, measured 10 cm from sounder, which is better than 65dB when driven with a ±1.5V 4 kHz square wave. Read more
Kyocera has announced the development of a new thermal printhead for desktop barcode printers. The new KRW Series features a simplified structure and refined sealant with improved assembly while helping to extend the life expectancy of printing equipment. The new series also offers superior corrosion resistance through use of an improved resin-sealant film which coats the surface of printhead. Read more
Mitsubishi Electric has developed a 638-nanometer (nm) wavelength red laser diode (LD) with output power of 1.8 W at continuous-wave operation, clicking the world’s highest level among the 638-nm LDs used as a light source for projectors. The luminosity of the new diode exceeds 220 lumens due to lasing at short wavelength. Read more
