  • Patent number: 9915991
    Abstract: A power state management system of an electronic system is coupled to a plug load device and a method for operation of the same. The system includes a context clock to adjust a duty cycle of the electronic system for controlling the power states of the electronic system for more efficient use of electricity. The context clock is responsive to user input, multiple event driven activities or an external protocol determined policy or command. Interface circuitry communicates user input, multiple event driven activities or an external protocol determined policy or command to the context clock. Interface circuitry also communicates commands to the managed plug load device or devices.
    Type: Grant

  • Publication number: 20150261644
    Abstract: A method of enabling a user of a power consuming devices to acquire energy consumption knowledge includes the steps of identifying a user communicating with a database, associating a physical and virtual environment of power consuming devices with the identified user, retrieving power consumption data with existing product information from the database, displaying to the user data of power consumption of a plurality of physical and virtual devices in the associated physical and virtual environment based on the current status of each device, and providing closed-loop feedback from the user to promote energy efficient devices and usage behavior of the user in the associated physical and virtual environment.

  • Patent number: 9040923
    Abstract: A tracking system for tracking an eye including a light source projecting light toward a display surface in a sequential pattern, one or more reflectors associated with an optical device, where the one or more reflectors reflect the pulses of light from the display source, one or more photo detectors, where the photo detectors detect reflected pulses of light from the light source, and a system that measures pulse timing relative to horizontal and vertical pattern to compute a gaze angle of the eye.

  • Patent number: 9024295
    Abstract: A 1D nanowire photodetector device includes a nanowire that is individually contacted by electrodes for applying a longitudinal electric field which drives the photocurrent. An intrinsic radial electric field to inhibits photo-carrier recombination, thus enhancing the photocurrent response. Circuits of 1D nanowire photodetectors include groups of photodetectors addressed by their individual 1D nanowire electrode contacts. Placement of 1D nanostructures is accomplished with registration onto a substrate. A substrate is patterned with a material, e.g., photoresist, and trenches are formed in the patterning material at predetermined locations for the placement of 1D nanostructures. The 1D nanostructures are aligned in a liquid suspension, and then transferred into the trenches from the liquid suspension. Removal of the patterning material places the 1D nanostructures in predetermined, registered positions on the substrate.

  • Publication number: 20100295019
    Abstract: A practical ID nanowire photodetector with high gain that can be controlled by a radial electric field established in the ID nanowire. A ID nanowire photodetector device of the invention includes a nanowire that is individually contacted by electrodes for applying a longitudinal electric field which drives the photocurrent. An intrinsic radial electric field to the nanowire inhibits photo-carrier recombination, thus enhancing the photocurrent response. The invention further provides circuits of ID nanowire photodetectors, with groups of photodetectors addressed by their individual ID nanowires electrode contacts. The invention also provides a method for placement of ID nanostructures, including nanowires, with registration onto a substrate. A substrate is patterned with a material, e.g., photoresist, and trenches are formed in the patterning material at predetermined locations for the placement of ID nanostructures.
