  • Publication number: 20150115332
    Abstract: The invention describes image sensor array pixels with global and rolling shutter capabilities that utilize multiple BCMD transistors for storing and sensing charge for a single photodiode. This configuration improves the Dynamic Range (DR) of the sensor, by allowing sensing different image signals from a single pixel without saturation, a low level signal with long integration time followed by a high level signal with short integration time. Signal processing circuits can process these signals into a single Wide Dynamic Range (WDR) output. Further disclosed are pixels that use multiple-gate BCMD transistors for charge storage and sensing having multiple concentric gates, which allows changing the conversion gain of the BCMD transistors. Variable conversion gain is a useful feature when building WDR sensors since low conversion gain and high well capacity allows detection of high level signals and, at the same time, low level signals with high conversion gain and low noise.

  • Patent number: 8946845
    Abstract: The invention describes in detail a solid-state CMOS image sensor, specifically a CMOS image sensor pixel that has stacked photo-sites, high sensitivity, and low dark current. The pixels have incorporated therein special potential barriers under the standard pinned photodiode region that diverts the photo-generated electrons from a deep region within the silicon bulk to separate storage structures located at the surface of the silicon substrate next to the pinned photodiode. The storage structures are p channel BCMD transistors that are biased to a low dark current generation mode during a charge integration period. The signal readout from the BCMD is nondestructive, therefore, without kTC noise generation. Thus a single pixel is capable of detecting several color-coded signals while using fewer or without using any light absorbing color filters on top of the pixel.

  • Patent number: 8928792
    Abstract: The invention describes a solid-state CMOS image sensor array and discloses image sensor array pixels with global and rolling shutter capabilities that utilize multiple BCMD transistors for a single photodiode, for charge storage and sensing. Thus, the valuable pixel area saved by employing the BCMD transistor for charge storage and sensing is used by placing several BCMD transistors coupled to one photodiode. This increases the Dynamic Range (DR) of the sensor, since the same photodiode can integrate charge for different integration times, both long and short. This allows sensing of two different image signals from a single pixel without saturation, a low level signal with long integration time followed by a high level signal with short integration time. The signal processing circuits located at the periphery of the array can then process these signals into a single Wide Dynamic Range (WDR) output.

  • Publication number: 20150005436
    Abstract: A thermoplastic elastomer (TPE) composition is provided which contains a blend of a hydrogenated styrenic block copolymer (SBC) having a number average molecular weight (Mn) greater than about 200,000 Daltons (Da), a polypropylene, a mineral oil, and at least one filler. The composition has a hardness less than about 80 Shore A and is resealable. An article produced from such a TPE composition reseals itself so as to exhibit no leakage after puncture. A method for preventing leakage in an elastomeric article involves providing an elastomeric article formed from the TPE composition, puncturing the elastomeric article by inserting a sharp object, and removing the sharp object; the article reseals itself such that no leakage occurs from the punctured article after removal of the sharp object.
