Disclosed is a liquid refrigerant reservoir and a cooling device comprised of at least one sorbent section, at least one liquid passageway section, at least one wicking material, at least one thermal spacer, a vapor-permeable membrane, a heat-removing material, at least one liquid barrier, a liquid refrigerant reservoir, and a valve. The sorbent section contains a sorbent for a liquid refrigerant. The liquid passageway section is adjacent the sorbent section and defines a liquid passageway through a portion of the evacuated sorbent assembly and cooling device to the sorbent section. The wicking material is disposed in the liquid passageway section. The thermal spacer is in contact with the sorbent section. The vapor-permeable membrane is interposed between the liquid passageway section and the thermal spacer. The heat-removing material is in thermal contact with the sorbent. The liquid barrier is interposed between the heat-removing material and the sorbent. The liquid refrigerant reservoir is adjacent the liquid passageway section. The valve controls liquid communication between the liquid passageway section and the liquid refrigerant reservoir. The cooling device includes a casing that surrounds the sorbent section, liquid passageway section, wicking material, thermal spacer, vapor-permeable membrane, heat-removing material, liquid barrier, liquid refrigerant reservoir, and valve.

摘要:
Methods of making vacuum insulation products are provided. One method includes providing an insulative mixture comprising an insulative material, such as silica, with a radiation absorbent material, such as carbon black, and applying electromagnetic radiation such as microwave radiation to the insulative mixture to dry the insulative mixture. The insulative mixture can then be placed into an enclosure and sealed within the enclosure. The enclosure can be evacuated before sealing to reduce the pressure within the enclosure to below atmospheric pressure. The use of radiation such as microwave radiation to dry the insulative mixture advantageously reduces the time required to fabricate the vacuum insulation product and can reduce the pressure that is obtained in the vacuum insulation product, thereby increasing thermal performance of the product.

A personal cooling device using a sorption cooling system to provide cooled fluid to a garment and methods relating to the same are provided. The sorption cooling system generally includes a lightweight, compact evaporator and adsorbent bed for providing the cooled fluid to the garment.
摘要:
A sorption cooling system for providing cooled air to the cabin of a vehicle. The sorption cooling system includes an evaporator, a condenser adapted to fluidly communication with the evaporator, and a plurality of adsorbent beds adapted for fluid communication with the condenser and the evaporator. Each adsorbent bed includes a fluid impermeable casing, desiccant sheets having apertures therethrough, a refrigerant flow path for flowing a refrigerant proximal to a first side of the desiccant sheets, and a coolant flow path for flowing a coolant fluid proximal to a second side of the desiccant sheets. The apertures are a portion of one of the refrigerant and coolant flow paths.
摘要:
A device and a method are disclosed including a unified format medical information and teleconferencing service (UFMITS) and client devices that communicate with such service, the UFMITS configured to obtain and view different format medical data, such as high resolution medical imaging data, convert the different formats to a unified format, and make such data available to the client devices via a single user interface. In operation, a medical agent, such as a surgeon, connects to the UFMITS, via a network, and requests medical data for a particular patient. The UFMITS sends medical information available about the particular patient to the medical agent in the unified format, enabling the medical agent to view all pertinent medical data using a single software interface. Furthermore, the medical agent may teleconference with other medical agents, via the UFMITS, to discuss such downloaded medical data, which are simultaneously downloaded to the other medical agents.
摘要:
A Wireless LAN Context Control Protocol (WLCCP) is used to establish and manage a wireless network topology and securely manages the “operational context” for mobile stations in a campus network. The WLCCP registration protocol can automatically create and delete links in the network, securely distribute operational context, and reliably establish Layer 2 forwarding paths on wireless links. A single infrastructure node is established as the central control point for each subnet, and enables APs and MNs to select the parent node that provides the “least-cost path” to a backbone LAN. Context messages provide a general-purpose transport for context and management information. WLCCP “Trace” messages facilitate network diagnostic tools. Ethernet or UDP/IP encapsulation can be used for WLCCP messages. Ethernet encapsulation is employed for intra-subnet (e.g. AP-to-AP or AP-to-SCM) WLCCP messages. IP encapsulation is used for inter-subnet WLCCP messages and may also be used for intra-subnet WLCCP messages.
摘要:
A method and system for handling roaming mobile nodes in a wireless network. The system uses a Subnet Context Manager to store current Network session keys, security policy and duration of the session (e.g. session timeout) for mobile nodes, which is established when the mobile node is initially authenticated. Pairwise transit keys are derived from the network session key. The Subnet Context Manager handles subsequent reassociation requests. When a mobile node roams to a new access point, the access point obtains the network session key from the Subnet Context Manager and validates the mobile node by computing a new pairwise transient key from the network session key.

A bleed air valve system is provided that includes a housing, a piston, a cap, a poppet, a first guide ring, and a second guide ring. The housing includes an upper valve seat extending radially inwardly therefrom. The piston is located at least partially in the housing. The cap is coupled to the housing and includes an annular axial section located therein and a lower valve seat. The poppet is located at least partially within the housing and includes a piston coupling section, a valve body section having an upper valve seat contact surface and a lower valve seat contact surface extending radially outwardly therefrom, and a guide section extending through the cap annular axial section. One guide rings is coupled to the piston to contact the housing inner surface. Another guide ring is coupled to the poppet guide section and contacts the cap annular axial section.
