Appl. No.:

11/212445

Inventors:

Vincent Nguyen - Houston TX, US
David W. Vice - Houston TX, US

International Classification:

B65B 31/04

US Classification:

53408, 53434, 53 79

Abstract:

A vacuum sealing method and system for evacuating air from and sealing a flexible plastic bag of the type having a mating male rib and a female sealing channel closure along the length of the bag opening. A flowable liquid is applied to the female channel. The rib and channel are engaged along their length to leave a short portion of the closure unclosed, a hollow tubular evacuation tube connected with a vacuum pump is inserted into the bag through the unclosed portion, pinching pressure is manually applied to sandwich the evacuation tube between the unclosed portion to prevent air from escaping, the vacuum pump is operated to withdraw a substantial amount of air from the bag, and thereafter the evacuation tube is quickly pulled from the bag so that the pinching pressure is transferred to the closure thereby closing the unclosed portion and sealing the evacuated bag with the liquid filling voids between the mating elements and providing a supplemental seal to increase resistance to air entering the sealed bag.

International Classification:

H01R 13/62

US Classification:

439301

Abstract:

Embodiments of a tamper-evident connector are disclosed which may optionally be used in a trusted computing environment. In an exemplary embodiment, a tamper-evident connection includes a mate-once engaging assembly for providing with a first component, the mate-once engaging assembly including a foldable portion. The tamper-evident connection also includes a receiving chamber for providing with a second component, the mate-once engaging assembly fitting in the receiving chamber to physically secure the first component to the second component, the foldable portion of the mate-once engaging assembly unfolding during removal of the mate-once engaging assembly from the receiving chamber to provide evidence of tampering when the first component has been removed from the second component. Optionally, the first component is a Trusted Platform Module (TPM) and the second component is a system board.

US Classification:

710 62, 709219, 709223

Abstract:

A multi-server computing system includes a plurality of server modules mounted in an enclosure; each server has a universal serial bus (USB) interface. An enclosure onboard administration (OA) module is also mounted in the enclosure and has an addressable communication interface for connection to a remote management system and a USB interface connected to each of the plurality of servers. The USB interface of the enclosure OA operates as a master and the USB interface of each of the plurality of servers acts as a slave to the enclosure OA, such that each of the server modules can be managed by the remote management system using a single communication address.

International Classification:

G06F 1/32

US Classification:

713324, 713320

Abstract:

Embodiments of a system and method for controlling power consumption in a computing device having at least one CPU and memory. Embodiments reduce or increase the amount of memory available to the at least one CPU in response to changes in power consumption and/or changes in temperature. In some embodiments the amount of memory accessible to the CPU is decreased or increased, in other embodiments the power setting applied to portions of memory is decreased or increased.
