Development of Industry’s First Monolithic Optical Proximity/Illumination Sensor with Touchless Motion Detection Capability by ROHM
Rohm made an announcement on development of industry’s first single-chip optical proximity/illumination sensor IC featuring touchless motion detection functionality targeted at electronic devices using touch panel such as smart phones and digital cameras. The new optical proximity sensor will be incorporated into these devices in order to turn the touch sensor and LCD panel ON or OFF when the phone is moved away from to and from user’s ear; it is also used for adjusting the brightness of the screen based on the ambient conditions resulting in longer battery life. The single chip BH1771GLC comes with two photodiode, one for detecting visible light and another one for infrared light detection providing the capability of proximity sensing from 1 to 10cm plus brightness from 0 to 65,000 lux. The BH1771GLC’s industry’s first touchless motion detection function is comprised of maximum 3 infrared LEDs where the phase differences of the reflected light from each LED is detected in determining the direction of movement of the reflecting object such as human hand, making it possible to operate a display panel without directly touching the screen by simply moving an object at an approximately 5cmm above the panel providing capability of motion operation in such display devices which are not equipped with a touch panel. In addition to this Rohm offers high power infrared LEDs optimized for use with BH1771GLC such as the SIM-030 with height of only 0.9mm and output power of approximately 30mW for creation of high performance touchless motion sensing solutions. The newly developed BH1771GLC will be available for sampling from December of 2009, with OEM quantities from June of 2010. The price per unit is set at 250 yen.

[...] Motion tracking system for motion tracking of hand, person or other object is considered to be one the core technologies for next generation applications in various fields, requiring sensors with a wide dynamic range of control for detecting wide range of motion from low speed to high speed. One of the companies in Japan that has been developing sensor products is Epson Toyocom Corporation. The company made an announcement on development of the world’s smallest single package 6-axis sensor. The newly developed AH-6100LR, is a low noise, low power sensor comprise of a 3-axis QMEMS quartz gyro-sensor (miniature, high performance crystal devices produced in quartz material via a microfabrication process), and an extremely stable 3-axis accelerometer all within a single package. Among some of the features on this newly developed AH-6100LR are wide dynamic range of 81 to 83 dB (200 Hz bandwidth), compact size of (100 x 8.0 x 3.8t mm), world’s lowest current consumption of 6.1 mA for a six-axis sensor, 5,000 g shock resistance, analog output for high accuracy sensing, build-in low-pass filter. The company will begin sample shipment of new AH-6100LR within February 2010, with commercial development for May 2010. source Share and Enjoy: [...]
