A method for conditioning a liquid cryogen in a tank includes reducing a pressure of the liquid cryogen in the tank for reducing a temperature of the liquid cryogen and condensing any vapor boil-off in the tank for reclaiming the liquid cryogen in the tank. The liquid cryogen may be selected from the group consisting of liquid nitrogen (LIN), liquid oxygen (LOX), and liquid argon (LAR).

Cryocooler health monitoring systems and methods are provided. In one example, a method includes determining, for each setpoint temperature of a plurality of setpoint temperatures, a respective power applied to a cryocooler to set a cold tip of the cryocooler to the setpoint temperature. The method further includes determining a first load line associated with the cold tip based on the plurality of setpoint temperatures and the respective powers applied to the cryocooler. The method further includes determining a health metric associated with the cold tip based on the first load line and a reference load line associated with the cryocooler. Related devices and systems are also provided.

Standalone and self-contained cooling systems using compressed liquid and/or gas CO.sub.2 containers positioned in an insulated or non-insulated vessel encompassing a container which is either vertically positioned in an upright or an upside-down position. The liquid and/or gas CO.sub.2 coolant is then released into a capillary system or flow metering system to allow the CO.sub.2 to enter a second body to where the CO.sub.2 coolant properties may be leveraged. The second body includes, by way of example, a plate, a cushion, a spot treatment pad for a person's muscle, or a cooler. The temperature is controlled by a metering CO.sub.2 releasing system encompassing an electronic control device which sends alerts when pre-defined thresholds are exceeded. The invention's metering CO.sub.2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid.

Particulate material is cooled by passing into the material a coolant stream of liquid nitrogen having a gaseous product around at least a portion of the liquid nitrogen, wherein the coolant stream is formed outside the particulate material in a nozzle body from which the coolant stream is passed into the particulate material.

A refrigerator is provided, including rare earth cold accumulating material particles filled in a cold accumulating vessel. The rare earth cold accumulating material particles are a rare earth oxide or a rare earth oxysulfide. The rare earth cold accumulating material particles define a sintered body. An average crystal grain size of the sintered body is 0.5 to 5 μm, a porosity of the sintered body is 10 to 50 vol. %, and an average pore size of the sintered body is 0.3 to 3 μm. In an arbitrary cross-section of the rare earth cold accumulating material particles, a number of pores per a unit area of 10 μm×10 μm is 20 to 70.

A remote system for monitoring and controlling one or more devices for use in the cryogenic processing of a sample is provided. A remote server capable of transmitting freezing profile data to one or more freezers, transmitting transportation profile data to one or more transportation devices, and transmitting thawing profile data to one or more thawing devices. The remote server is also capable of receiving detected data from the one or more freezers relating to the freezing of a sample in accordance with the freezing profile data, receiving detected data from the one or more transportation devices relating to the transportation of a sample in accordance with the transportation profile data, and receiving detected data from the one or more thawing machines relating to the thawing of a sample in accordance with the thawing profile data.

The present disclosure provides cryogenic storage systems and methods of using the cryogenic storage systems. A cryogenic storage system of the present disclosure may comprise a cryogenic tank with an inner door and an outer door, and a robot apparatus located adjacent to the cryogenic tank. The cryogenic tank may store multiple racks such that at most a single rack is removable through the inner door or the outer door. The cryogenic tank may store the multiple racks in multiple groups of racks comprising a first group of racks located at a first radial distance and a second group of racks located at a second radial distance that is greater than the first radial distance. The robot apparatus may selectively open and close the inner or outer doors, and insert or withdraw the single rack into or out of the cryogenic tank through the inner door or the outer door.

A temperature control system is used for controlling a temperature of a control target to a target temperature that changes with lapse of time. The system includes: a first adjustment apparatus that includes a first tank that stores a first heat transfer medium, adjusts the temperature of the first heat transfer medium to a first set temperature, and supplies the temperature-adjusted first heat transfer medium; a first circulation circuit through which the first heat transfer medium flows from the first adjustment apparatus to a first flow-through path and returns to the first adjustment apparatus; an adjustment section that adjusts an amount of heat supplied from the first flow-through path to the control target; a memory that stores a relation between the lapse of time and the target temperature; and a controller.

An signal switching integrated-circuit die includes an array of switch cells, control signal contacts, data input contacts and data output contacts. Switch control signals are received from an external control-signal source via respective control signal contacts, inbound data signals are received from one or more external data-signal sources via respective data input contacts and outbound data signals are conveyed to one or more external data-signal destinations via respective data output contacts. The array of switch cells receives the control signals directly from the control signal contacts and response to the control signals by switchably interconnecting the data input contacts with selected ones of the data output contacts.

A remote system for monitoring and controlling one or more devices for use in the cryogenic processing of a sample is provided. A remote server capable of transmitting freezing profile data to one or more freezers, transmitting transportation profile data to one or more transportation devices, and transmitting thawing profile data to one or more thawing devices. The remote server is also capable of receiving detected data from the one or more freezers relating to the freezing of a sample in accordance with the freezing profile data, receiving detected data from the one or more transportation devices relating to the transportation of a sample in accordance with the transportation profile data, and receiving detected data from the one or more thawing machines relating to the thawing of a sample in accordance with the thawing profile data.
