  • Publication number: 20220145479
    Abstract: Described herein are systems and methods for the management and control of electrolyte within confined electrochemical cells or groups (e.g. stacks) of connected electrochemical cells, for example, in an electrolyzer. Various embodiments of systems and methods provide for the elimination of parasitic conductive paths between cells, and/or precise passive control of fluid pressures within cells. In some embodiments, a fixed volume of electrolyte is substantially retained within each cell while efficiently collecting and removing produced gases or other products from the cell.

  • Patent number: 11325370
    Abstract: A fluidic die including fluid chambers, each including an electrode exposed to an interior of the fluid chamber and each having a corresponding fluid actuator operating at a first voltage level. Monitoring circuitry, operating at a second voltage level lower than the first voltage level, includes a select transistor and a pulldown transistor for each fluid chamber to selectively couple to the electrode, at least the select transistor being a high voltage tolerant transistor to operate at the second voltage in a normal operating condition and having a breakdown voltage level greater than the first voltage level to prevent a fault current from flowing into the select transistor from the electrode in a fault condition if the fluid actuator short-circuits to the electrode.

  • Patent number: 11292250
    Abstract: In one example in accordance with the present disclosure, a fluidic die is described. The fluidic die includes an array of fluid actuators grouped into primitives. Each actuator is disposed in a fluid chamber. The fluidic die also includes an array of fluid sensors. Each fluid sensor is disposed within a fluid chamber and determines a characteristic within the fluid chamber. A data parser of the fluidic die extracts from an incoming signal, firing instructions and measurement instructions for the fluidic die. The measurement instructions indicate at least one of a peak measurement during a nucleation event and a reference measurement during a non-nucleation event. A firing controller generates firing signals based on the firing instructions and a measurement controller activates, during a measurement interval of a printing cycle for the primitive, a measurement for a selected actuator based on the measurement instructions.

  • Publication number: 20220088789
    Abstract: A temporary-storage system that includes a temporary-storage belt, a control unit and signalling means. The temporary-storage belt comprises a plurality of regularly distributed sensors. During a loading phase, the control unit receives information coming from at least one of the sensors when an object is deposited on the temporary-storage belt and records a trace of the deposition of the object in association with a reference to each of the sensors activated by the deposition. During an unloading phase, the control unit determines a sequence of removal of the objects and, for each object to be removed, identifies the sensors referenced, transmits to the signalling means signalling information identifying the position of the object, and receives information coming from at least one of the sensors when the object is removed.
