    Abstract: Schedule-based energy storage device selection is described for a device having an energy storage device system with heterogeneous energy storage devices, such as heterogeneous battery cells. The techniques discussed herein use information regarding a user's schedule (e.g., the user's calendar) to predict future workload patterns for a computing device and reserve energy storage device capacities across multiple heterogeneous energy storage devices to improve efficiency of the energy storage devices. For example, if a user is expected to attend a video conference call later in the day (e.g., due to the video conference call being on the user's calendar), then energy in an energy storage device that is better capable of handling such a workload (providing power during the video conference call) more efficiently is preserved so that the energy is available when the video conference call occurs.

  • Patent number: 9144139
    Abstract: An occupancy sensor with integral light level sensors is configured to turn off or disable peripheral circuits and go into a periodic deep sleep mode to reduce phantom loading. Peripheral circuits include occupancy sensor circuits and relay drive circuits, but may include other circuits such as communication circuits. The sensor may be configured to periodically wake itself up, check ambient light conditions to see if lighting is below the set threshold. If it is not, the sensor goes back to sleep. If it is, then the sensor can power up the occupancy sensor circuit to see if the space is occupied; if not, it can go back to sleep. If the space is occupied, it can turn on other peripheral circuits necessary to control the load.

    Abstract: Electrical power is dynamically managed among one or more power sources and one or more loads. A plurality of monitor nodes is connected to an input terminal connected to each source, and to an output terminal connected to each load. A plurality of electrical power storage cells is connected among the input and output terminals, each cell being capable of storing power from at least one of the sources and being capable of discharging stored power to at least one of the loads. A plurality of controllable switches is connected to the cells. A programmed controller dynamically monitors operating conditions at the monitor nodes during operation of each source and each load, and selectively dynamically controls the switches to interconnect the cells in different circuit topologies in response to the monitored operating conditions.

  • Patent number: 8994211
    Abstract: According to one embodiment, a circuit for providing redundant power includes a first channel having a first input, a first electronic circuit breaker, and a first output, a second channel having a second input, a second electronic circuit breaker, and a second output, and a first transistor coupled to the first electronic circuit breaker, the first transistor in series with a second transistor coupled to the second channel. The circuit normally operates by providing power to the first and second outputs from the first and second channels, respectively. However, if the first channel fails, the transistors switch on to allow power from the second channel to feed the first output in the first channel in addition to feeding power to the second output, and vice versa. Other embodiments and methods for providing redundant power are described as well.

    Abstract: Systems and methods are provided for regulating the state of charge of a battery. An exemplary electrical system includes a fuel cell coupled to a bus and a battery coupled to the bus via a switching arrangement coupled to a capacitor. An exemplary method for operating the electrical system involves operating the switching arrangement such that a voltage of the battery is substantially equal to a voltage of the fuel cell when a state of charge of the battery is greater than a lower threshold value and less than an upper threshold value, and operating the switching arrangement to couple the capacitor electrically in series between the battery and the bus when the state of charge of the battery is not between the lower threshold value and the upper threshold value.
