A 1.5Mpixel RGBZ image sensor that simultaneously captures color (RGB) and time-of-flight (ToF) range (Z) images is presented. While ToF sensors are well documented [1,2], few, if any, monolithic sensors have been reported that capture both range and color. In one sensor [3], a combined pixel structure captures color and range, but presumably in sequential(More)
A highly compact ambient-light-cancellation (ALC) circuit for 3D time-of-flight (ToF) image sensor pixels is presented. It is implemented in a 320x240 pixel (QVGA) sensor with 14um pixel pitch in a 90 nm backside illumination (BSI) image sensor process. The ALC circuit has less than 3% fill factor impact and is very suitable for scaling to smaller pixels.(More)
Heavy vehicles are significantly longer and heavier than passenger cars and consequently have quite different acceleration and braking capabilities. Heavy vehicle manoeuvres are therefore likely to influence drivers' vehicle-following behaviour differently to cars. Heavy vehicles can also influence the behaviour of drivers of other vehicles while following(More)
Mandibular condyle plays an important role in the growth and reconstruction of the temporomandibular joint (TMJ). We aimed to obtain orthotropic elastic parameters of the condyle using a continuous-wave ultrasonic technique and to observe the effects of condylar elastic parameters on stress distribution of the TMJ using finite element analysis (FEA). Using(More)
