A method and apparatus for powering up and powering down a laser diode and its driver are disclosed. The disclosed method and apparatus enable the use of deep sub-micron CMOS technology to build a laser diode driver (LDD), while ensuring the low voltage limits prescribed by such technology are not exceeded. Building an LDD with deep sub-micron CMOS technology pushes circuit integration further ahead, bringing cost of LDDs and required board circuits down.

An in-band OTDR uses a network's communication protocols to perform OTDR testing on a link. Because the OTDR signal (probe pulse) is handled like a data signal, the time required for OTDR testing is typically about the same as the time required for other global network events, and is not considered an interruption of service to users. A network equipment includes an optical time domain reflectometry (OTDR) transmitter and receiver, each operationally connected to a link to transmit and receive, respectively, an OTDR signal. When an OTDR is to be performed, a network device operationally connected to the link actuates the OTDR transmitter to transmit the OTDR signal on the link during a determined test time based on a communications protocol of the link, during which data signals are not transmitted to the network equipment. A processing system processes the OTDR signal to provide OTDR test results.

According to the invention, a system for dynamically scaling bias current on an imaging system is disclosed. In the invention an image sensor capable of producing at least a two-dimensional image and capable of at least two modes of operation is equipped with a control unit. The control unit determines a digital output for each of the modes of operation of the imaging system and outputs the digital outputs to a converter. The converter converts the digital output from the control unit to a bias current and provides this output to an analog and or mixed signal circuit associated with the imaging system that has operating characteristics that may be varied by the application of different bias currents.

Systems and methods for dynamic current scaling of analog functions in an imager

The present invention provides systems and methods capable of reducing power consumption in an imaging device. One imaging device includes two analog to digital converters that are separately programmable and can be in different power modes. Each analog to digital converter is capable of creating an image derived from a pixel array that has a full field of view, but lower resolution.

The pixel includes a reset element () used in relation to charging a light sensitive element (). Further, the pixel includes a charge evacuation element () for dissipating charge build up about the reset element. Dissipation of the charge results in a reduction of noise at the output of the pixel.

Pixel sensor with charge evacuation element and systems and methods for using such

An image capture device includes a focusing lens, a light sensor array having a plurality of pixels arranged in a matrix of rows and columns and a plurality of optical components. Each optical component is configured to focus light on a light-sensing portion of one of the pixels. The locations of the optical components define a grid of parallel and perpendicular lines and a line spacing of the grid varies as a function of a distance from an optical axis of the focusing lens.
