Low Power Gesture Recognition

Now Playing: Continuous low-power music recognition

Existing music recognition applications require a connection to a server that performs the actual recognition. In this paper we present a low-power music recognizer that runs entirely on a mobile device and automatically recognizes music without user interaction. To reduce battery consumption, a small music detector runs continuously on the mobile device’s digital signal processor (DSP) chip an...

Low-Power Reduced Transistor Image Sensor

An image sensor comprising an array of 128 by 50 super pixels, column parallel current conveyors and global difference double sampling (DDS) unit is presented. The super pixel consists of: a reset transistor, a readout transistor, four transfer transistors and four photodiodes. The photo pixel address switch is placed outside the pixel, effectively implementing 1.5 transistors per pixel using a...

Low Power Highly Miniaturized Image Sensor Technology

A second generation image sensor technology has been developed at the NASA Jet Propulsion Laboratory with performance comparable to charge-coupled device (CCD's). This sensor is implemented using the industry-stand&d complementary metal-oxide semiconductor (CMOS) technology employed for nearly all microprocessors and memory chips and thus takes advantage of the rapid worldwide development of th...
