Abstract:

A system and method for remote capture, identification, cataloging, and modeling of processes remotely captures the processes performed by a user on a machine, for example, a computer. Capture may include capturing input to the computer and manual tasks via video and/or audio capture. The tasks are identified, cataloged and stored. Modeling is possible by streaming the captured data back to a computer. The captured data may be edited and the edited versions compared or benchmarked by performing simulations of each.

International Classification:

F03B 3/04
F03B 13/00
F04B 19/04

Abstract:

Disclosed techniques include working fluid exergy recovery using hybrid processing. A supply of working fluid at a first pressure and a first temperature is accessed. The working fluid is compressed. The compressing yields the working fluid at a second pressure. The second pressure is greater than the first pressure. The working fluid at the second pressure and a second temperature is warmed using a first heat exchanger. The second temperature is greater than the first temperature. The working fluid at the second temperature is in a gaseous state. The working fluid is expanded in a gaseous state to a third pressure. The expanding is accomplished using a first liquid piston expander. An engine is driven to recover work from the working fluid in a gaseous state. The engine is powered by liquid from the first liquid piston expander.

F04B 53/08

Abstract:

Disclosed techniques include gas liquefaction using hybrid processing. A gas is compressed adiabatically to produce a compressed gas at a first pressure. The compressing a gas adiabatically is accomplished using one or more compressing stages. Heat is extracted from the compressed gas at a first pressure. The heat that is extracted is collected in a thermal store. The compressed gas at a first pressure is further compressed. The further compressing is accomplished using a first liquid piston compressor. The further compressing produces a compressed gas at a second pressure. The first liquid piston compressor is cooled using a liquid spray. The compressed gas at a second pressure is cooled using a heat exchanger. The cooling accomplishes liquefaction of the compressed gas at a second pressure. The gas that was liquefied is stored for future use. The gas that was liquefied is used to perform work.

International Classification:

H02J 9/06
H05K 7/14
G06F 1/26

Abstract:

Datacenter current injection for power management is disclosed. A controller for managing power control modules and current sensing for a datacenter power infrastructure unit is provided. At least three power control modules coupled to the controller are each connected to each phase of a three-phase datacenter power grid. Current sense inputs for each phase of the datacenter power grid are coupled to the controller. At least three battery modules are coupled to a corresponding power control module. The coupling provides an energy path between a battery module and phase of the three-phase datacenter power grid. The coupling is managed by the controller. Each power control module includes a battery charging unit and a current mode grid tie inverter unit. The current mode grid tie inverter unit enables current injection into each phase of the three-phase datacenter power grid at constant voltage and in-phase AC frequency for the phase.

Abstract:

Techniques for datacenter power management using dynamic redundancy are disclosed. A power control switch is configured to selectively apply power to one or two power cords of a dual-corded electronic apparatus. When the power control switch energizes both power cords, the electronic apparatus operates in 2N redundancy. When the power control switch energizes only one of the power cords, the electronic apparatus operates in 1N redundancy. The power control switch is configured to dynamically change the redundancy mode based on service level agreement (SLA) criteria, power policies, power supply and demand, and environmental factors.

International Classification:

G05B 19/042
H02J 15/00
F04D 25/06

Abstract:

Disclosed techniques include power management using pressure amplification. An energy conversion requirement for a fluid-based energy management system is determined. The energy management system includes a pump-turbine subsystem connected to one or more pressure amplification pipes. Energy is provided to the energy management system, based on the energy conversion requirement. The energy is transformed using the pump-turbine subsystem connected to one or more pressure amplification pipes. The pump-turbine subsystem is operated at an optimal pressure-performance point for the pump-turbine subsystem. The energy that was transformed is delivered, where the delivering is accomplished using the pump-turbine subsystem connected to one or more pressure amplification pipes. The energy management system is operated by an energy management control system. The energy management control system controls coupling of the energy, the pump-turbine subsystem, and the one or more pressure amplification pipes.
