  • Publication number: 20240349460
    Abstract: Disclosed is a containerized heating, ventilation, and air-conditioning (HVAC) system comprising an HVAC unit and one or more ducts from the HVAC unit to an equipment rack. The ducts prevent mixing between the fresh and exhaust airflow, thus improving efficiency. Sensors located at sources of heat generating equipment within the racks may be used by controllers to monitor temperatures of the components at the source of heat generation, typically at the highest temperatures. The temperatures may be aggregated to determine the temperatures of devices, modules, racks, and the container interior cavity. Dampers on the ducts, at the rack inlets, at the module inlets, at the devices inlets, and such may assist in regulating airflow preferentially to the hottest components, devices, modules, or racks.

  • Patent number: 9490283
    Abstract: An imaging device formed as an active pixel array combining a CMOS fabrication process and a nanowire fabrication process. The pixels in the array may include a single or multiple photogates surrounding the nanowire. The photogates control the potential profile in the nanowire, allowing accumulation of photo-generated charges in the nanowire and transfer of the charges for signal readout. Each pixel may include a readout circuit which may include a reset transistor, charge transfer switch transistor, source follower amplifier, and pixel select transistor. A nanowire is generally structured as a vertical rod on the bulk semiconductor substrate to receive light energy impinging onto the tip of the nanowire. The nanowire may be configured to function as either a photodetector or a waveguide configured to guild the light to the substrate. Light of different wavelengths can be detected using the imaging device.
