摘要:
A power throttling method and system for a memory controller in a computer system comprising a power supply module including a plurality of bulk power supplies (“BPSs”) are described. In one embodiment, each of the at BPSs provides to a power output monitor a status signal indicative of a status thereof. Responsive to receipt of the status signals, the power output monitor determines whether a bulk power supply capacity is below system power requirements. Responsive to a positive determination, the power output monitor drives a throttle control signal to the memory controller to a level indicative of an over-threshold state.

The present invention determines temperature and current from resistance measurements of a single magnetoresistive sensor. A dual-purpose sensor includes the magnetoresistive sensor having a single pair of terminals. The sensor is multiplexed under separate current conditions to produce both a temperature measurement and a current measurement in a vicinity of the sensor. A sensor system includes the dual-purpose sensor, a resistance sensing subsystem and a controller that controls the current conditions. A method of measuring temperature and current includes measuring a first resistance of the dual-purpose sensor while a first current is flowing in a conductor adjacent to the sensor, and measuring a second resistance of the sensor while a second current is flowing in the conductor. The first current has a known value while the second current has an unknown value. The temperature and current are determined respectively from the first and second resistance measurements.

A fused power cable assembly and method of integrating a protective device with a power source connector retaining bracket. A bracket assembly having a bulkhead retaining element, a protective device element, and a retaining element operable to couple the protective device to the bracket allows for mounting of protective device(s) to the bracket instead of the bulkhead, thereby saving space. A power cabling assembly having a bracket assembly, a power connector, and a fastening element operable to couple the power connector to the bulkhead and the bulkhead to the bracket assembly, allowing assembly of the power cabling assembly prior to installation into target equipment.

A first printed circuit board is built including one or more openings configured to correspond to heat-generating devices attached to a second printed circuit board. The first and second printed circuit boards are aligned with each other and a heat sink, such that the heat sink is thermally coupled with heat-generating electronic devices on both the first and second printed circuit boards. Optionally, the first and second printed circuit boards may be electrically coupled with each other through an electrical connector. Also optionally, heat-generating devices may be mechanically and electrically coupled with the second printed circuit board through interposers configured (upon assembly) to raise the heat-generating devices through the openings in the first printed circuit board to contact a heat sink.

Embodiments include apparatus, methods, and systems of an electronic module for a system board having at least one pass-thru hole. An exemplary electronic module, connectable to a system board with a pass-thru hole, includes a first portion coupled to one side of the system board. The first portion has a printed circuit board (PCB) with plural processors. A second portion of the electronic module couples to a second, opposite side of the system board. The second portion has a power system board electrically coupled to the first portion. The second portion also includes a thermal dissipation device that extends through the pass-thru hole of the system board.

Embodiments include apparatus, methods, and systems having a multi-chip module with stacked redundant power. An exemplary apparatus has a module having plural processors. A first power system is coupled, in a vertically stacked configuration, to the module for providing power to the module. A second power system provides power to the module and is coupled, in a vertically stacked configuration, to the first power system. Each power system serves as a duplicate for preventing failure of the module upon failure of one of the power systems. A thermal dissipation device is disposed between both the first and second power systems and the first power system and module such that the thermal dissipation device dissipates heat, via heat exchange, away from the processors, the first power system, and the second power system.

A first heat sink is built including two sets of fins with a gap between the two fin sets. The gap is configured to allow the placement of a second heat sink between the two fin sets of the first heat sink. The first heat sink also includes slotted mounting lugs to allow the second heat sink to be mounted to the first heat sink allowing for varying stack up tolerances of the heat generating devices cooled by the first and second heat sinks.
摘要:
A multiple-input redundant power system accepts both AC and DC power inputs. Redundancy is further provided by the use of converters for the AC input, and converters for the DC input. An output distribution element provides for simple combining of converter outputs, and for more complex load sharing and load control arrangements. Advantages accruing from the AC/DC input approach are savings in facility infrastructure, since existing power sources can be utilized, and high availability and reliability in accordance with certain embodiments. The approach has many applications in computing and telecommunications.
