  • Patent number: 9471128
    Abstract: User interfaces are provided that display application energy usage information to a user. Application energy usage information may be displayed as an energy meter user interface that provides derived information (e.g., power and time used to determine energy usage) that is not available through a traditional activity monitor. For example, energy usage information is provided for an application running in isolation, taking into account energy usage based on what the application is doing and not what the rest of the system is doing (e.g., shows CPU wakes in isolation of any other processes). Each of a series of energy bars is presented as an energy utilization metric that includes at least one of a utilization portion and a wake tax portion, combined to represent to represent total energy utilization.

  • Patent number: 8943871
    Abstract: A crash sled system for simulating the deceleration and pitching motion associated with vehicle crashes. A main sled is accelerated in accordance with vehicle deceleration that occurred during a crash event. A pitching platform is located above and moves with the main sled. Forward and rear guide assemblies are provided which are located along the sides of the pitching platform when the main sled and pitching platform are in the pre-launch position. When the main sled is launched, the front and rear ends of the pitching platform travel along paths established by the guide assemblies. Prior to launch, the guide assemblies are set to angles of inclination that provide linear approximations to paths for the forward and aft ends of the pitching platform that will result in pitching motion experienced by vehicles during the crash events being simulated. Variously configured guide assemblies are disclosed that provide design trade-off between simulation accuracy and system complexity.

    Abstract: A method and system of tolerance testing a component using data measurements from a single test setup within a test apparatus are described. The method includes receiving the data measurements obtained with the single test setup. The method also includes separating, at the processor, the data measurements from a relative positioning of an element of the test apparatus and performing, at the processor, a virtual setup of the component to obtain additional data measurements related to one or more parts of the component. The method additionally includes determining, at the processor, whether a parameter associated with the one or more parts meets a specified tolerance based on the additional data measurements obtained from the virtual setup.

The controller includes a processor and a preset angle module. The preset angle module is connected to the processor and stores a preset angle. The processor controls the driver to lift up a side of the machine cabinet. If the cabinet does not topple, the driver keeps lifting up the side of the machine cabinet until the tilt angle equals the preset angle, and the cabinet is deemed to meet a standard.
