This vision sensor outputs luminance, contrast magnitude and contrast orientation of image features for surveillance and automotive applications. The sensor produces a contrast representation with a dynamic range of 120 dB and a sensitivity of 2%. The chip is fabricated in a 0.5 /spl mu/m 3M 2P process and dissipates 300 mW at 3.3 V.
A 1 V wireless SoC embedding an RF transceiver, a sensor interface, a 6.4 MHz RISC micro-controller with an 8k instruction SRAM and a power management unit is reported. The radio supports 25 kb/s FSK and 2 kb/s OOK modulations in the 433/868 MHz bands. In the 433 MHz band, the receiver draws 2.1 mA while providing a sensitivity of -108 dBm and the… (More)
This application-specific integrated circuit (ASIC) computes two optically encoded positions, each engraved in a pattern onto one of a two-cylinder assembly. The cylinders are coupled by a torsion bar of known stiffness so that the difference between the two extracted positions provides a torque measurement to be used in next-generation automobile… (More)
