  • Patent number: 10707683
    Abstract: Generally, this disclosure relates to methods of prioritizing or directing available power to a main device, such as a temperature-stabilized and/or temperature-controlled storage container. In an embodiment, the method may include measuring electrical power available from a solar photovoltaic module array that is electrically coupled to the main device, and modulating the electrical power drawn by the main device based on the available electrical power. Available power unused by the main device may be diverted to one or more secondary devices.

  • Patent number: 10619916
    Abstract: A refrigeration device includes a thermal transfer unit with an evaporative region, an adiabatic region, and a condensing region with a reversible valve attached to the adiabatic region. The device includes a container sealed around PCM, with a set of refrigeration coils of a compressor unit in thermal contact with the PCM. A storage region is in thermal contact with the evaporative region of the thermal transfer unit. A controller is operably connected to the reversible valve and the refrigeration compressor unit. The storage region can be used to store cold packs within a predetermined temperature range for medical outreach.

  • Patent number: 8205856
    Abstract: A metering assembly includes a fluidic chip and metering chambers. Selectable outlet valves communicate with each metering chamber to provide a discrete dispensed volume. The valves may be commonly controlled and may be formed as multi-level valves. The valves may be grouped into common substrate valve clusters. Purge channels communicate with the metering chambers and controlled purge valves allow reverse flow wash fluid to wash the metering chamber. Pressure ports are employed to actuate the valves. A method of dispensing a fluid from the fluidic chip includes a) to selectively filling (or filling) the metering chambers with a selected fluid; and b) outputting (or selectively outputting) the fluid to output locations. The total output volume of fluid dispensed from each metering chamber may be accumulated. The process may be repeated until the accumulated volume equals the desired volume and may be repeated for another fluid from a plurality of different fluids.
