  • Patent number: 11031615
    Abstract: A method of operating a fuel cell stack is described. The fuel cell stack includes a cathode, an anode, a sump configured for collecting water from the anode, and a temporarily disabled drain valve that is otherwise configured to transition from a first position to a second position and thereby modulate water drained from the sump. The method includes increasing a first pressure in the anode via a controller. The method also includes, concurrent to increasing, decreasing a second pressure in the cathode via the controller and, concurrent to decreasing, maintaining a relative humidity of less than a threshold relative humidity in the cathode via the controller.

  • Patent number: 10964235
    Abstract: An electronic device may include a display. The display includes display driver circuitry for driving data lines routed across the display. The electronic device may have a recessed device housing region, where at least some of the data lines are routed around the recessed region. The data lines being routed around the recessed region may be formed in at least two different metal routing layers. The electronic device may further include additional display driver circuitry for driving data lines from another peripheral housing edge to obviate the need to route around the recessed region. The data lines from the two display driver circuitries can be disconnected at random locations or can be interlaced to achieve spatial interleaving. The display driver circuitry may include demultiplexing circuitry having smaller switches coupled in parallel with larger demultiplexer routing switches to reduce voltage kick and charge injection.

  • Publication number: 20210063493
    Abstract: An anode system is arranged to supply pressurized hydrogen to the anode of a fuel cell, and includes a multi-injector system. A controller is executable to monitor, via a pressure sensor, pressure in the anode system and command actuations of the plurality of hydrogen injectors. The controller may detect a fault in the multi-injector system when the commanded actuations of the plurality of hydrogen injectors are greater than a first threshold and the pressure in the anode system cell is less than a second threshold. The controller may execute alternating actuation of the hydrogen injectors of the multi-injector system and monitor the pressure in the anode system to detect a fault in one of the hydrogen injectors based upon the pressure in the anode system.

  • Patent number: 10923015
    Abstract: A display device may include a plurality of pixels that may display image data on a display. The display device may also include a circuit that may receive pixel data including a gray level for at least one pixel of the plurality of pixels. The circuit may then receive an emission clock signal using a clock circuit based on the pixel data, such that the emission clock signal may cause the at least one pixel to receive a current for an amount of time based on the gray level. The circuit may then gate off the clock circuit after the amount of time.

  • Patent number: 10880330
    Abstract: System and method for detecting an infected website are disclosed. A semantic finder receives top-level domains and identifies keywords of the top-level domains representing a predetermined semantics. The keywords are compared with irrelevant bad terms to find at least one irrelevant term. An inconsistency searcher searches the top-level domains and detects at least one fully-qualified domain name carrying the at least one irrelevant term. A context analyzer evaluates context information associated with the irrelevant term, identifies at least one frequently-used term identified in the context information, and determines whether the at least one frequently-used term is unrelated to a generic content of the at least one fully-qualified domain name An irrelevant bad term collector extracts the at least one frequently-used term unrelated to the generic content and adds the extracted frequently-used term to an irrelevant bad term list for detecting the infected website.
