Publication number: 20100143770Abstract: A low pressure current interrupt device (CID) activates at a minimal threshold internal gauge pressure in a range of, for example, between about 4 kg/cm2 and about 9 kg/cm2. Preferably, the CID includes a first conductive plate and a second conductive plate in electrical communication with the first conductive plate, the electrical communication between the first and the second conductive plates being interrupted at the minimal threshold internal gauge pressure. More preferably, the first conductive plate includes a frustum having a first end and a second end, a base extending radially from a perimeter of the first end of the frustum, and an essentially planar cap sealing the second end of the frustum. The first end has a broader diameter than the second end. More preferably, the second conductive plate is in electrical contact with the essentially planar cap through a weld. A battery, preferably a lithium-ion battery, comprises a CID as described above.Type: ApplicationFiled: November 20, 2009Publication date: June 10, 2010Inventors: Per Onnerud, Phillip E.

Publication number: 20050180326Abstract: A system and method for providing services such as Wake-on-LAN and PXE Boot services to a multi-subnet network system which includes router and/or firewalls between different subnets. This is accomplished by using a peer computer to provide the service when performing such service is required to be transmitted across the router and/or firewall. That is, the system determines whether the service is required to go across the router and/or firewall, and, if so, to identify a computer (a peer computer) which is located on the appropriate subnet, then deliver the service to that peer computer (if necessary) and have that peer computer perform the selected service, such as Wake-on-LAN.Type: ApplicationFiled: February 13, 2004Publication date: August 18, 2005Inventors: Michael Goldflam, Jan Roger Jonsson, Juliano Maldaner, Sulay Shah, Frank Wang
