The present invention relates to a system for monitoring an electromechanical relay, wherein the electromechanical relay includes a relay coil for actuating at least one switch, the system comprising: at least one sensor adapted to measure an operating condition of the electromechanical relay, wherein the sensor is arranged adjacent or attached to the electromechanical relay; at least one controller communicatively connected to the at least one sensor and at least one memory, wherein the at least one controller is adapted to store the measured operating condition in the at least one memory; at least one transmitter, operatively connected to the controller, wherein the transmitter is adapted to transmit the stored measured operating condition to a remote device.

System for monitoring an electromechanical relay, assembly and method for monitoring relay operation conditions

In various embodiments, a time-delay-and-integrate (TDI) image sensor includes (i) a plurality of integrating CCDs (ICCDs), arranged in parallel, that accumulate photocharge in response to exposure to light, (ii) electrically coupled to the plurality of ICCDs, a readout CCD (RCCD) for receiving photocharge from the plurality of ICCDs, and (iii) electrically coupled to the RCCD, readout circuitry for converting charge received from the RCCD into voltage.

Time-delay-and-integrate image sensors having variable integration times

Time-delay-and-integrate image sensors having variable intergration times

A method for reading out an image signal includes providing at least two photosensitive regions and providing at least two transfer gates respectively associated with each photosensitive region. The method also includes providing a common charge-to-voltage conversion region electrically connected to the transfer gates and providing a reset mechanism that resets the common charge-to-voltage conversion region. After transferring charge from at least one of the photo-sensitive regions, all the transfer gates are disabled at a first time. The method further includes enabling at least one transfer gate at a subsequent second time and transferring charge from at least one of the photosensitive regions at a subsequent third time while the at least one transfer gate from the second time remains enabled.

Image sensor pixel with gain control

A method for forming a final digital color image includes capturing an image using an image sensor having panchromatic pixels and color pixels corresponding to at least two color photoresponses; providing from the captured image a digital panchromatic image and an intermediate digital color image; and using the digital panchromatic image and the intermediate digital color image to provide the final digital color image.

Processing color and panchromatic pixels

An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. An analog front end (AFE) circuit processes pixel data output from the output circuits and an AFE clock controller transmits an AFE clocking signal to the AFE circuit to effect processing of the pixel data. A timing generator outputs a column address sequence that is received by a column decoder. During one or more sample operations the timing generator suspends the column address sequence and subsequently during the one or more sample operations the AFE clock controller suspends the AFE clocking signal. The AFE clocking signal and the column address sequence resume at the end of the one or more sample operations.

Pausing column readout in image sensors

An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. An analog front end (AFE) circuit processes pixel data output from the output circuits and an AFE clock controller transmits an AFE clocking signal to the AFE circuit to effect processing of the pixel data. A timing generator outputs a column address sequence that is received by a column decoder. During one or more sample operations the AFE clock controller suspends the output of the AFE clocking signal and the timing generator suspends the output of the column address sequence during the sample operation. The output of the AFE clocking signal and the column address sequence resume at the end of the sample operation.

Suspending column readout in image sensors

A method for using a capture device to capture at least two video signals corresponding to a scene, includes: providing a two-dimensional image sensor having a plurality of pixels; reading a first group of pixels from the image sensor at a first frame rate to produce a first video signal of the image scene; reading a second group of pixels from the image sensor at a second frame rate for producing a second video signal; and using at least one of the video signals for adjusting one or more of the capture device parameters.

Providing multiple video signals from single sensor

An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. A timing generator outputs a column address sequence that is received by a column decoder that is electrically connected to each output circuit. The timing generator suspends the output of the column address sequence during a sample operation and resumes the output of the column address sequence at the end of the sample operation.

Suspending column addressing in image sensors

An imaging system and method for producing a digital image from pixel signals captured by a pixel array is disclosed. First pixel signals, generated during a first exposure period, are read out from a first group of pixels of the pixel array. The first group of pixels is reset after reading out the first pixel signals. Second pixel signals from the first group of pixel are read out after resetting the first group of pixels. The second pixel signals are generated during a second exposure period. Third pixel signals from a second group of pixels of the pixel array are read out. The third pixel signals are generated during a third exposure period that overlaps at least a portion of the first and second exposure periods. The first, second, and third pixel signals are used to produce the digital image.

Exposing pixel groups in producing digital images

An image sensor for capturing a color image is disclosed having a two-dimensional array having first and second groups of pixels wherein pixels from the first group of pixels have narrower spectral photoresponses than pixels from the second group of pixels and wherein the first group of pixels has individual pixels that have spectral photoresponses that correspond to a set of at least two colors. Further, the placement of the first and second groups of pixels defines a pattern that has a minimal repeating unit including at least twelve pixels. The minimal repeating unit has a plurality of cells wherein each cell has at least two pixels representing a specific color selected from the first group of pixels and a plurality of pixels selected from the second group of pixels arranged to permit the reproduction of a captured color image under different lighting conditions.

Image sensor with improved light sensitivity

Multiple images are captured where the exposure times for some of the images overlap and the images are spatially overlapped. Charge packets are transferred from one or more portions of pixels after particular integration periods, thereby enabling the portion or portions of pixels to begin another integration period while one or more other portions of pixels continue to integrate charge. Charge packets may be binned during readout of the images from the image sensor. Comparison of two or more images having different lengths of overlapping or non-overlapping exposure periods provides motion information. The multiple images can then be aligned to compensate for motion between the images and assembled into a combined image with an improved signal to noise ratio and reduced motion blur.

Methods for capturing and reading out images from an image sensor

A method for reading out pixel values for a two dimensional array, the method includes the steps of periodically combining at least two pixel values of a same first color in a first dimension of the two dimensional array; reading out the combined pixel values of the first color; and reading out pixels of a second color in the first dimension of the two dimensional array.
