Disclosed is a system for thermally conditioning and pumping a fluid. The system includes a thermoelectric heat exchanger having a thermoelectric device configured to pump heat. Heat exchangers are provided for transferring heat to and from the thermoelectric device and for generating a fluid flow across the thermoelectric device. The conditioned fluid may be placed in thermal communication with a variety of objects, such as a vehicle seat, or anywhere localized heating and cooling are desired. Thermal isolation may also be provided in the direction of flow to enhance efficiency.

Various present invention devices enable adherence to requirements for medical items. A medical item of the present invention includes a monitoring or data recording device to monitor and/or record medical solution conditions. The device may further include indicators to indicate compliance of the medical solution with prescribed requirements (e.g., manufacturer, medical standard or regulation, etc.). The medical item may alternatively include a barcode or transponder to uniquely identify the medical item to a thermal treatment system measuring and storing conditions in a central database. The present invention further includes various thermal treatment systems that monitor medical items for prescribed requirements and display the monitored parameters to medical personnel. In addition, the present invention may place time stamp information on medical items to enable determination by medical personnel of compliance with prescribed requirements.

Described is a data communication protocol, in which a client and server negotiate in a manner that does not require the client to retry negotiation when servers are not capable of the client-desired protocol. In one example implementation, the desired protocol is SMB 2.0 or greater. The protocol describes a create command with possibly additional context data attached for built-in extensibility, and a compound command comprising a plurality of related commands or unrelated commands. A multi-channel command requests data transfer on a separate data channel, a signed capability verification may be used to ensure that a secure connection is established, and the protocol provides the ability to transfer extended error data from the server in response to a request.

A number of compact, high-efficiency and high-power density thermoelectric systems utilizing the advantages of thermal isolation are described. Such configurations exhibit high system efficiency and power density. Some configurations exhibit a substantial reduction in the amount of thermoelectric material required.

High power density thermoelectric systems

Laboratory apparatus for optionally heating or cooling samples, comprising a block of one or more Peltier elements which, with one of their thermal poles, are in thermal contact with an essentially rectangular block of heat conducting metal, and with the other pole are in thermal contact with a heat exchanger, this latter being thermally insulated from the metal block. One of the outer surfaces of the rectangular metal block serves as a working outer surface for heating or cooling the samples. All outer surfaces of the metal block, with the excption of the working surface and the surface in contact with the Peltier elements, are thermally insulated. The working surface may be used for heating or cooling at will through the inversion of the direction of the alimentation current for the Peltier elements.

Laboratory apparatus for optional temperature-controlled heating and cooling

A novel portable thermoelectric cooling and heating food appliance adapted for use in a vehicle by travelers, hunters, and campers. A base unit (10) is provided which is activated when connected to the vehicle cigarette lighter receptacle and by utilizing thermoelectric Peltier elements (41, 42) and through a selective control system offers the heating and cooling to various appliances that can be detachably attached to the base unit (10) and adapted through conducting transfer plates (47, 72) to heat and cool the appliance (56) contents, which will retain a desired temperature when removed from the base unit (10) with the use of a to heat and cool bottom slide cover sealing off conducting plate (74). Ice cube making utilizes air-conditioner cold air ducted into area (11) cooling the action element (43) and at the same time further cooling ambient air in the vehicle.
