  • Patent number: 10691787
    Abstract: A method and apparatus for reading unique identifiers of an integrated circuit. The unique identifiers may be physically unclonable functions (PUFs), formed by high energy ions implanted into semiconductor material of the integrated circuit. The method may include electrically or optically stimulating each of the PUFs and sensing with an optical sensor optical characteristics of resulting light emitted from the PUFs. Then the method may include comparing values associated with the optical characteristics of the PUFs with groups of stored values in a circuit database. Each of the groups of stored values may be associated with optical characteristics of PUFs of a known authentic circuit. The method may then include the controller providing verification of authenticity of the integrated circuit when each of the values associated with the optical characteristics of the PUFs match the stored values of at least one of the groups in the circuit database.

  • Patent number: 10681284
    Abstract: A pixel array uses two sets of pixels to provide accurate exposure control. One set of pixels provide continuous output signals for automatic light control (ALC) as the other set integrates and captures an image. ALC pixels allow monitoring of multiple pixels of an array to obtain sample data indicating the amount of light reaching the array, while allowing the other pixels to provide proper image data. A small percentage of the pixels in an array is replaced with ALC pixels and the array has two reset lines for each row; one line controls the reset for the image capture pixels while the other line controls the reset for the ALC pixels. In the columns, at least one extra control signal is used for the sampling of the reset level for the ALC pixels, which happens later than the sampling of the reset level for the image capture pixels.

  • Patent number: 10641639
    Abstract: A liquid level sensing system provides a removable reservoir incorporating a reflective surface that can be interrogated by a stationary optical sensor in a receptacle receiving the removable reservoir. The optical sensor may detect the presence of the liquid within the reservoir without connection to the reservoir simplifying the process of making the reservoir removable while still allowing sensing of its contents. By aligning the optical axis with the insertion axis of the reservoir sensitive optical alignment problems are minimized.

  • Patent number: 10644652
    Abstract: In optical receivers, extending the transimpedance amplifier's (TIA) dynamic range is a key to increasing the receiver's dynamic range, and therefore increase the channel capacity. Ideally, the TIA requires controllable gain, whereby the receiver can modify the characteristics of the TIA and/or the VGA to process high power incoming signals with a defined maximum distortion, and low power incoming signals with a defined maximum noise. A solution to the problem is to provide TIA's with reconfigurable feedback resistors, which are adjustable based on the level of power, e.g. current, generated by the photodetector, and variable load resistors, which are adjustable based on the change in impedance caused by the change in the feedback resistor.

  • Patent number: 10634813
    Abstract: Embodiments are directed towards a safety system that can be used with a high-flux power beam, such as in wireless power transmission. The system includes a transmitter that generates and transmits a power beam and a receiver that receives the power beam. A plurality of sensors is configured to independently detect if an object is near, impeding, or about to impede (i.e., impinging) the power beam. Each of the plurality of sensors is configured to detect the object at different distances between the transmitter and the receiver. A controller triggers the transmitter to stop generating the power beam when any one or more of the plurality of sensors detects the object or a combination of the plurality of sensors detects the object. The controller triggers the transmitter to re-generate and transmit the power beam when each of the plurality of sensors fails to detect the object.
