摘要:
Data pertaining to environmental information is acquired using sensors on a multiplicity of networked pervasive devices, and analyzed to determine occurrence of at least one environmental event. Such data can be obtained, for example, from an inventive wireless communications device including an antenna, transmit circuitry coupled to the antenna for transmission of radio frequency radiation therefrom, at least one environmental sensor configured to obtain environmental data, and a communications module coupled to the at least one environmental sensor and configured to cause transmission of a representation of the data via the antenna and the transmit circuitry.

Systems and methods for cooling include one or more computing structure, an inter-structure liquid cooling system that includes valves configured to selectively provide liquid coolant to the one or more computing structures; a heat rejection system that includes one or more heat rejection units configured to cool liquid coolant; and one or more liquid-to-liquid heat exchangers that include valves configured to selectively transfer heat from liquid coolant in the inter-structure liquid cooling system to liquid coolant in the heat rejection system. Each computing structure further includes one or more liquid-cooled servers; and an intra-structure liquid cooling system that has valves configured to selectively provide liquid coolant to the one or more liquid-cooled servers.
摘要:
Cooling apparatuses are provided to facilitate active control of thermal and fluid dynamic performance of a coolant-cooled cold plate. The cooling apparatus includes the cold plate and a controller. The cold plate couples to one or more electronic components to be cooled, and includes an adjustable physical configuration. The controller dynamically varies the adjustable physical configuration of the cold plate based on a monitored variable associated with the cold plate or the electronic component(s) being cooled by the cold plate. By dynamically varying the physical configuration, the thermal and fluid dynamic performance of the cold plate are adjusted to, for example, optimally cool the electronic component(s), and at the same time, reduce cooling power consumption used in cooling the electronic component(s). The physical configuration can be adjusted by providing one or more adjustable plates within the cold plate, the positioning of which may be adjusted based on the monitored variable.

Several apparatuses and methods for providing cooling system interchangeability. One apparatus includes a thermally conductive plate thermally coupled to an integrated circuit. The thermally conductive plate is configured to couple interchangeably to a liquid cooling assembly or an air cooling assembly, and the liquid cooling assembly and the air cooling assembly are separate devices.

An electronic device includes: at least one electronic chip comprising a first coefficient of thermal expansion (CTE); and a carrier including a top surface connected to the bottom surface of the chip by solder bumps. The carrier further includes a second CTE that approximately matches the first CTE, and a plurality of through vias from the bottom surface of the carrier to the top surface of the carrier layer. Each through via includes a collar exposed at the top surface of the carrier, a pad exposed at the bottom surface of the carrier, and a post disposed between the collar and the pad. The post extends thorough a volume of space.

A system and method of attaching a heat sink to an integrated circuit chip includes providing a compliant material for constraining the heat sink's mechanical motion while simultaneously allowing for thermal expansion of the heat sink.
摘要:
A disk drive which incorporates separate actuators for each recording head so as to only place required recording heads over the recording media of multiple surface hard disk drives. The reduction in recording heads that are placed over the recording media reduces drag on the rotating disk holding the recording media and thereby reduces the power consumption. Reducing the number of recording heads over the recording media also reduces damage to the recording media surfaces in the event of a physical shock to the drive since inactive transducer heads are not in a position to damage the recording media.
