A mobile computing device includes a first video camera on a first side of the mobile computing device producing a first camera video stream. A second video camera is on a second side of the mobile computing device producing a second camera video stream. A video processor is coupled to the first video camera and the second video camera to receive the first camera video stream and the second camera video stream, respectively. The video processor is coupled to merge the first camera video stream and the second camera video stream to generate a merged video stream. The video processor includes a network interface coupled to upload the merged video stream to a server in real-time using an Internet wireless network. The server broadcasts the merged video stream to a plurality of receivers in real-time.

An image sensor pixel includes a photodiode region formed in a semiconductor layer, a pinning layer and a depletion adjustment layer. The photodiode region receives visible and infrared light from a light incident side of the image sensor pixel. The pinning layer is disposed between a front surface of the semiconductor layer and the photodiode region, while the depletion adjustment layer is disposed between the pinning layer and the photodiode region. The depletion adjustment layer is configured to adjust a depletion region of the photodiode region to reduce charge carriers induced in the photodiode region by the received infrared light.

An image sensor includes a pixel array having a plurality of pixels. A readout circuit is coupled to the pixel array. A controller circuit is coupled to control the pixel array and is coupled to the readout circuit to receive array data from the pixel array. The controller circuit includes a mode control logic unit providing logic which when executed causes the image sensor operate in an idle mode of operation and then sample in response to receiving an event signal array data received from the pixel array in a pulsed mode of operation. A pattern in the array data samples over time is recognized and a mode of operation is selected in response to the recognized pattern.

A location tracking service includes a location tracking server and individual tracking modules. An individual tracking module can be attached or embedded in a consumer product. Each tracking module is programmable by an end-user to include a private ID that is sent along with tracking data to the location tracking server. The end-user can define and edit the private ID in the tracking module independent of the location tracking service to improve privacy protection. The tracking data may include raw (unprocessed) location data to reduce processing requirements at the tracking module.

A system and method for applying a layer of material in the image sensor fabrication process in order to increase the absorption of specific range light spectrum by the image sensor is described. The mechanism adopted is by converting light rays from higher energy range (shorter wavelength) to lower energy range (longer wavelength) such that the light absorption by the image sensor can be increased.
