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.

Directing or modulating electrical power drawn by one or more loads from a solar photovoltaic module array while maintaining a buffer margin

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.

Devices for use with refrigeration devices including temperature-controlled container systems

A device, method, and system are provided for monitoring the delivery of fluids through a drip chamber. The device includes an electromagnetic radiation (EMR) source and an EMR detector. A device body is employed to position the source and detector about the drip chamber so that the source and detector define an optical path across the drip chamber. A processor device is employed to detect fluid drops from differences between detector signal values separated by a lag time. The flow rate is determined from a drip factor and the detection of multiple drops. In the context of delivering intravenous (IV) fluids, a battery powered handheld monitoring device that includes the source, detector, device body, and processor device may be affixed to a drip chamber included in an infusion set. The device includes a user interface, including buttons, a display, and an audio speaker, for the input and output of information.

Device, method, and system for monitoring the delivery of fluids through a drip chamber

In some embodiments, a refrigeration device includes: walls substantially forming a liquid-impermeable container configured to hold phase change material internal to the refrigeration device; at least one active refrigeration unit including a set of evaporator coils positioned at least partially within the liquid-impermeable container; a unidirectional thermal conductor with a condensing end and an evaporative end, the condensing end positioned within the liquid-impermeable container; a first aperture in the liquid-impermeable container, the first aperture of a size, shape and position to permit the set of evaporator coils to traverse the aperture; a second aperture in the liquid-impermeable container, the second aperture including an internal surface of a size, shape and position to mate with an external surface of the unidirectional thermal conductor; and one or more walls substantially forming a storage region in thermal contact with the evaporative end of the unidirectional thermal conductor.

Refrigeration devices including temperature-controlled container systems

In some embodiments, a refrigeration device includes: walls substantially forming a liquid-impermeable container configured to hold phase change material internal to a refrigeration device; at least one active refrigeration unit including a set of evaporator coils positioned within an interior of the liquid-impermeable container; walls substantially forming a storage region; and a heat transfer system including a first group of vapor-impermeable structures with a hollow interior connected to form a condenser in thermal contact with the walls substantially forming a liquid-impermeable container, a second group of vapor-impermeable structures with a hollow interior connected to form an evaporator in thermal contact with the walls substantially forming a storage region, and a connector with a hollow interior affixed to both the condenser and the evaporator, the connector forming a liquid and vapor flow path between the hollow interior of the condenser and the hollow interior of the evaporator.

In some embodiments, a temperature-controlled container for use within a refrigeration device includes: one or more sections of insulation material substantially defining one or more walls of a temperature-controlled container, the temperature-controlled container including an internal region; a thermally-insulated partition dividing the internal region to form a storage region and a phase change material region internal to the container, the thermally-insulated partition including a conduit between the storage region and the phase change material region; a thermal control device within the conduit; an aperture within a section of the insulation material substantially defining the container, the aperture between the phase change material region internal to the container and an external surface of the container; and a unidirectional thermal conductor positioned within the aperture, the unidirectional thermal conductor configured to transmit heat in a direction from the phase change material region to the external surface of the container.
