A capillary pump two phase heat transport system that combines the most favorable characteristics of a capillary pump loop (CPL) with the robustness and reliability of a loop heat pipe (LHP). Like a CPL, the hybrid loop has plural parallel evaporators, plural parallel condensers, and a back pressure flow regulator. Unlike CPLs, however, the hybrid system incorporates elements that form a secondary loop, which is essentially a LHP that is co-joined with a CPL to form an inseparable whole. Although secondary to the basic thermal management of the system thermal bus, the LHP secondary loop portion of the system provides for important operational functions that maintain healthy, robust and reliable operation. The LHP secondary loop portion provides a function of fluid management during start-up, steady state operation, and heat sink/heat source temperature and power cycling.

Methods and systems are presented for controlling power cycling in a global positioning system (GPS) assembly. The assembly comprises a power management component that operates to switch a GPS receiver between at least a first mode, in which the receiver is actively receiving almanac and positioning data, and a second mode, in which the receiver does not actively receive data according to a power cycling routine of the receiver. A memory stores a plurality of quanta of almanac data as associated memory blocks, each memory block having an associated status indicating the length of time for which the associated almanac data is expected to be useful. A signal processing component processes a received signal containing at least a portion of a quantum of almanac data and identifies the quantum of almanac data within the received signal. A receiver control adjusts the power cycling routine of the GPS receiver according to the associated status of a memory block associated with the identified quantum of almanac data.

An apparatus and method for tracking aircraft wingtip position during taxi operations to prevent wingtip ground incursion. A patterned illumination source is attached proximal the wingtips to project a readily discernable target pattern in the direction of taxi travel. At least a portion of the target pattern is reflected off of any obstructions that lie in the straight-line direction of travel, such that the pilot can maneuver to avoid striking the obstruction. By way of example, the patterned illumination source comprises a laser module positioned with the navigation and/or strobe light of the aircraft. The device may be retrofitted to existing aircraft without additional wiring with the control of activation being selectable via power cycling of existing aircraft lighting controls. One aspect of the invention provides a tip tracking module bulb that may be retrofitted into existing light sockets to simplify system installation.

Techniques for initializing/reinitializing a device on an expansion card without power cycling the system. More specifically, an instruction set is provided such that a device on an expansion card can be reinitialized without power cycling the system. Further, the instruction set may be implemented to initialize a device on a replacement expansion card. During the system boot, an expansion basic input/output system (BIOS) is copied into the system memory. After the system boot, a copy of the configuration information for the device on the expansion card is saved in a backup file in the system memory. The expansion card can be removed and replaced and the configuration information stored in the backup file in the system memory can be used to configure the replacement device. The copy of the expansion BIOS in the system memory can be reprogrammed such that it can be implemented to initialize the device on the replacement expansion card without power cycling the system.

A method and system in a computer having a primary video controller for dynamically selecting an alternative video controller present within the computer. Initially, a diagnostic is performed to determine if alternative video controllers are connected to the computer system. A user is thereafter prompted to select an alternative video controller, if at least one alternative video controller is detected. The primary video controller is then temporarily disabled, in response to a selection of an alternative video controller. The alternative video controller is then automatically designated as the primary video controller, in response to the disabling of the primary video controller, such that the alternative video controller may be temporarily utilized as a primary video controller without altering internal computer system hardware settings or power cycling the computer system. The primary video controller may be implemented initially as an on-board video controller, while the alternative video controllers may be connected to the computer via adapter peripheral cards and slots.

Secure boot ROM emulation with locking storage device. A locking storage device is provided by combining a nonvolatile memory device such as flash or EEPROM with one-shot locking logic which write enables at least a portion of the nonvolatile memory device upon power cycling of the overall digital device. This write enable is cleared during the stage 1 bootloader process, thus providing a protected update interval for updating a stage 2 bootloader once per power cycle.

A method and system for managing peripheral connection wakeup signaling in a processing system supporting multiple virtual machines provides a mechanism by which ownership of a peripheral having system wakeup capability is transferred between virtual machines. The power management event signal is connected to a service processor input that in turn signals a hypervisor to direct the wakeup activity to a particular logical partition in which the virtual machine was last executing. The hypervisor can then determine whether or not to wake up the entire system, or portions thereof and can direct the power management event to the appropriate virtual machine. In particular the peripheral may be an Ethernet adapter supporting Wake-On-LAN capability. State initialization, which is typically ensured by system power cycling is provided instead by controlling power to the standby power source or in some instances by forcing an indication of a disconnect/reconnect of the wakeup signaling connection.

An apparatus and method for tracking aircraft wingtip position during taxi operations to prevent collisions with nearby obstructions. A patterned illumination source is attached proximal the wingtips to project a readily discernable target pattern in the direction of taxi travel. At least a portion of the target pattern is reflected off of any obstructions that lie in the straight-line direction of travel, such that the pilot can maneuver to avoid striking the obstruction. By way of example, the patterned illumination source comprises a laser module positioned with the navigation and/or strobe light of the aircraft that is configured to project a circular pattern in front of the wingtip. The device may be retrofitted to existing aircraft without additional wiring with the control of activation being selectable via power cycling of existing aircraft lighting controls.

Secondary batteries are subjected to power cycling, and those which have a liquid electrolyte within the interior volume are equipped with a pressure relief valve. A void space over the liquid electrolyte may be subjected to gas pressure variations with respect to the ambient. The pressure relief valve structure comprises a vertically oriented gas flow chamber, and an outer relief vent adapted to open only when gas pressure within the battery and the gas flow chamber exceeds a predetermined pressure with respect to the ambient pressure. The gas flow chamber extends below the top surface of the battery, and has a dome-like cap which extends downwardly and has a plurality of openings so as to permit unimpeded gas flow between the interior of the battery and the gas flow chamber. There is a porous membrane covering the dome which permits gas flow between the interior of the battery and the gas flow chamber, but precludes flow of liquid electrolyte from the interior volume of the battery to the gas flow chamber.

A “Placement Detector” enables handheld or mobile electronic devices such as phones, media players, tablets, etc., to infer their current position or placement. Placement inference is performed by evaluating one or more sensors associated with the device relative to one or more trained probabilistic models to infer device relative to a user. Example placement inferences include, but are not limited to, inferring whether the device is currently in a user's pocket, in a user's purse (or other carrying bag or backpack), in a closed area such as a drawer or box, in an open area such as on a table, indoors, outdoors, etc. These types of placement inferences facilitate a wide range of automated user-device interactions, including, but not limited to, placement-dependent notifications, placement-dependent responses to various inputs, prevention of inadvertent “pocket dialing,” prevention of inadvertent power cycling of devices, lost or misplaced device location assistance, etc.
