Driver's gaze direction is a critical information in understanding driver state. In this paper, we present a distributed camera framework to estimate driver's coarse gaze direction using both head and eye cues. Coarse gaze direction is often sufficient in a number of applications, however, the challenge is to estimate gaze direction robustly in naturalistic(More)
A highly integrated WiFi/BT/FM/GPS connectivity combo SOC is implemented in a 60nm CMOS process. This work presents the proposed WiFi/BT merged RF transceiver, a virtual SP3T switch, and DPD algorithm to save chip area, reduce BOM and enhance performance simultaneously. The WiFi/BT/FM/GPS RF transceiver areas are 1.7/1.3/0.8/1.0mm<sup>2</sup>, respectively.(More)
This paper presents a 55nm 4-in-1 (11b/g/n, BT, FM, and GPS) radio assembled side-by-side with a 3-metal layer integrated-passive-device (IPD) chip in a QFN40 package. One 2.4GHz transceiver is area-efficiently shared between WiFi and Bluetooth systems. Including a 3dB IPD insertion loss, at chip output (antenna port) the saturated output power of the 11bgn(More)
