Abstract: Embodiments of on-demand power management have been presented. In some embodiments, a set of processing events on a system bus within a processing system is detected. Further, a processing event pattern may be recognized, and the processing event pattern may be correlated with a processing demand in the processing system.

Abstract: A remote sensor having a thermal transducer, an acoustic transducer, and a magnetic transducer. The remote sensor can communicate data from any of the transducers via any of three different communication links, which include an active RF transceiver, an IRDA transceiver, and an RF backscatter transceiver.

Abstract: A method for on-demand power management monitors a processing demand in a processing system operating at a first set of voltages and frequencies and generates a second set of voltages and frequencies in response to the processing demand. The method switches from the first set of voltages and frequencies to the second set of voltages and frequencies without halting the processing system.

Abstract: An apparatus for controlling switching transients including a bus interface unit and a waveform shaper coupled to the bus interface unit and a peripheral device. The bus interface unit generates a number of control signals defining the beginning and end of an operation, where each control signal includes a transition from a first value to a second value over a period of time. The bus interface unit selects a critical control signal defined as the last control signal to start the operation and/or the first control signal to end the operation. The waveform shaper receives the selected control signal and modifies the control signal by increasing the period of time of the transition. The modified control signal is received by the peripheral device and a switching transient in the peripheral device is controlled.

Abstract: An apparatus for on-demand power management including a system controller, a clock domain manager coupled to the system controller and a power distribution manager coupled to the system controller. The system controller monitors a processing demand in a processing system. The clock domain manager provides one or more clock frequencies and, in response to the processing demand, switches between a first set of clock frequencies and a second set of clock frequencies without halting the processing system. The power distribution manager provides one or more operating voltages and, in response to the processing demand, switches between a first set of voltages and a second set of voltages without halting the processing system.

Abstract: A standby generator integration system for efficiently integrating one or more standby generators into an operational power grid. The standby generator integration system includes a control center in communication with a plurality of control units. Each of the control units are in communication with a standby generator, the power grid and a contactor unit. The control unit calculates the hard minimum of the grid voltage and the generator voltage where switching is desired by summing the rectified voltages together. The control unit then initiates the closing of the contactor unit to bring the standby generator online with the power grid.

Abstract: An apparatus for controlling transient current peaks including a bus interface unit and a waveform shaper coupled to the bus interface unit and a peripheral device. The bus interface unit generates a control signal having a transition from a first value to a second value over a period of time. The waveform shaper receives the control signal and modifies the control signal by increasing the period of time of the transition.

Abstract: A power distribution control system for high speed electronics limits peak transient current when entering or exiting circuitry into or out of a system wide freeze mode. The power distribution control system includes power supply circuitry which provides a first supply voltage on a first output line. Multiple circuitry sections are each coupled to and powered by the power supply circuitry. While in the system wide freeze mode, each of the multiple circuitry sections is held inactive by a corresponding one of multiple control signals. A freeze controller is coupled to each of the circuitry sections, and provides the corresponding control signal to each circuitry section. The control signal provided to each particular circuitry section causes the particular circuitry section to enter or exit the system wide freeze mode independently of others of the multiple circuitry sections.

Abstract: A listening conditioning system includes an audio conditioning unit and optionally one or more audio delivery components. A receiver provides at least one receiver channel which receives signals indicative of sound from a source of desired sound, and provides as an output digital sound data for each receiver channel. Digital signal processing circuitry coupled to the at least one receiver channel filters the digital sound data from each receiver channel using a filter profile to obtain filtered digital sound data. A profile upload input is configured to receive a multiple filter profiles, wherein each of the filter profiles corresponds to user preferences or to an audiogram of a user of the listening conditioning system and to a particular sound environment. A profile selection user input can be used to select the filter profile from the multiple filter profiles. A transmitter coupled to the digital signal processing circuitry is configured to transmit filtered sound data from each receiver channel.

Abstract: A method of the invention, embodied for example as computer executable instructions stored on a computer readable medium and executed on a personal computer, includes obtaining a first filter profile for an audio conditioning unit of a sound conditioning system. The first filter profile corresponds to an audiogram of a user of the system. Sound data corresponding to audio to be played is obtained and filtered using the first filter profile. The filtered sound data is played for the user of the sound conditioning system. The user can adjust the first filter profile for current hearing capabilities and specific sound environments without the aid of an audiologist. Multiple filter profiles can be uploaded from the personal computer to an audio conditioning unit of a listening conditioning system.
