Abstract: A sensor device (10) for photon-based imaging comprising one or more photon detectors configured to produce a plurality of photon detection signals in response to a plurality of photon detection events, wherein each photon detection event has a corresponding detection time and wherein the detection times of the plurality of photon detection events are distributed in accordance with a distribution over time; and processing circuitry configured to perform a sketching process using timing information of the plurality of photon detection events to obtain a compressed representation of the distribution over time, wherein the sketching process comprises: generating a plurality of feature values based on the timing information of the plurality of photon detection events using one or more feature functions; combining the generated plurality of feature values to obtain the compressed representation of the distribution over time, wherein the feature functions have one or more properties such that combining the pluralit

Abstract: A composition includes a crosslinked polysiloxane elastomer with 2 or more carbon-oxygen-silicon linkages between a polysaccharide component and polysiloxane component, where the polysaccharide component is other than a cellulose or starch component.

Abstract: An automatic zoom-sensing riflescope display adapter (RDA) system can illuminate an iris of a user with a beam from a light emitter. The RDA system can activate a display which includes at least one graphical element visible by the user through an eyepiece. Additionally, the RDA system can focus an image of the iris on a sensor. The RDA system can determine a diameter of the iris from the image of the iris using an iris analyzer. The RDA system can develop a calibration table that correlates the diameter of the iris to a zoom level of an optical scope. The RDA system can estimate the zoom level of the optical scope from the diameter of the iris via the calibration table. Additionally, the RDA system can adjust, to match the zoom level, a font size of the at least one graphical element of the display.

Abstract: A medical device for cleaning a laparoscope can include a service box with a pump and a gas valve. Each of the pump and the gas valve can be in communication with an exit valve. The pump can be configured to draw fluid into the service box, along a fluid feed line, and out of the exit valve. The gas valve can be configured to selectively permit gas into the service box, along the fluid feed line, and out of the exit valve. The medical device can include a trocar that can be in communication with the exit valve via a flexible tubing. The trocar can include a hub and a cannula. The hub can be configured to receive and direct the laparoscope through the cannula. The cannula can be configured to receive fluid and gas from the exit valve and direct the fluid and gas to the open end.
