  • Patent number: 8827847
    Abstract: A training aid (10) provides real-time biometric feedback for swung or linearly accelerated implements where the feedback is provided above a user adjustable threshold. The training aid (10) includes a two-part housing (12) and mounting means for releasably mounting the housing to an implement. A battery (16) is located in the housing (12) with a buzzer (22) connected to the battery (16) through an electrical circuit. A force activated switch (14) in the electrical circuit is activated to energize the buzzer (22) to sound in response to displacement of the training aid. The force activated switch (14) has a force threshold at which the force activated switch (14) is activated to energize the buzzer (22) to sound. The force activated switch (14) is configured so that the force threshold is user adjustable.

  • Patent number: 8281163
    Abstract: Systems and methods for reducing problems and disadvantages associated with traditional approaches to masking false faults generated by voltage regulators are provided. A method may include receiving, at a voltage regulator configured to be enabled by a power controller communicatively coupled to the voltage regulator via an enable line, a first indication from a device other than the power controller indicating that the voltage regulator is to be disabled, wherein the enable line is configured to communicate a second indication from the power controller to the voltage regulator indicating whether the voltage regulator is to be enabled. In response to receipt of the first signal, the voltage regulator may communicate to the power controller via the enable line, a third indication indicating that the voltage regulator has been disabled by a device other than the power controller.

  • Patent number: 8104939
    Abstract: A solid-state light source (10) comprising a plurality of LED units (12) arrayed to emit light generally about an axis (14). Each of the LED units (12) can comprise a number of LEDs, for example, up to five. They may all emit in a single color or multiple colors can be combined for a specific effect. A light transmissive light guide (16) is associated with the LED units (12) and has a plurality of input widows (18). Each LED unit (12) faces a respective input window (18) and each window (18) transversely intercepts the axis (14) and receives light from the LED units (12). The input windows (18) lead to a common output window (20) that is axially aligned with the input windows (18). The light guide (16) has smooth sidewalls (22) that extend between the input windows (18) and the output window (20).

  • Publication number: 20110292802
    Abstract: Systems and methods for automatic throttling of resources in an information handling system are disclosed. A method may include determining whether a first throttling condition exists, the first throttling condition existing when a chassis management controller fails to communicate a clock or synchronization signal to one or more devices in an information handling system chassis for a particular duration of time. The method may also include determining whether a second throttling condition exists, the second throttling condition existing when the chassis management controller fails to communicate data to one or more devices in the information system handling chassis. The method may further include throttling a resource in the information handling system chassis if at least one of the first throttling condition and the second throttling condition exists.

  • Patent number: 7795632
    Abstract: An LED and light guide assembly has an LED with an output surface; a first power input lead electrically coupled to a first pole and having a first surface and a second surface; and a second power input lead electrically coupled to a second pole and having a first surface and a second surface. A unitary, molded light guide has an axially extending, light transmissive body with a light output window. An input window is formed with the unitary, molded light guide being aligned in a zero-gap relationship to capture substantially all the light emitted by the LED. A support is formed integral with the light guide and envelopes a portion of the first surface and the second surface of the first power input lead and the first surface and the second surface of the second power input lead to anchor the guide with respect to the power inputs.

An active layer, including quantum wells, is on the first conduction layer region. A trench is formed into the active layer region. The trench is formed in a wagon wheel configuration with spokes providing mechanical support for the active layer region. The trench is etched approximately to the first conduction layer region. Proton implants are provided in the wagon wheel and configured to render the spokes of the wagon wheel insulating. A nearly planar electrical contact is formed as an intracavity contact for connecting the bottom of the active region to a power supply. The nearly planar electrical contact is formed in and about the trench.
