  • Patent number: 11599179
    Abstract: A system, method, and non-transitory computer-readable medium are disclosed for intelligently controlling a power supply system of an information handling system. At least one embodiment is directed to a method that includes receiving power from an adapter and providing the power from the adapter to a switching power supply. At least one embodiment of the method also includes controlling the plurality of power switching elements to provide system power to an information handling system through the switching power supply; detecting a light loading power condition of the information handling system. In response to detecting the light loading power condition, the switching power supply is deactivated and a bypass control module is activated. In at least one embodiment, activation of the bypass control module directs power from the adapter through the bypass control module to the information handling system as the system power.

  • Patent number: 11392190
    Abstract: A system and method for powering up a portable information handling system based on a position of a kickstand and a position of a keyboard relative to a chassis. When a kickstand is opened, a power control system determines if a keyboard is attached and opened. If the keyboard is not attached and the kickstand is opened, the power control system initiates powering up the portable information handling system. If the keyboard is attached and closed, the portable information handling system is not powered up. If the keyboard is attached and opened, the power control system initiates powering up the portable information handling system. If the kickstand is opened and the keyboard is opened, the power control system initiates powering up the portable information handling system.

  • Publication number: 20140350885
    Abstract: A method for evaluating satellite positioning quality and a satellite receiver are disclosed. Satellite information is obtained from one or more satellites of the set of satellites. The satellite information includes an observed value of a parameter of each of the one or more satellites. An estimated value of each observed value is determined based on the satellite information. A set of residual values between the estimated values and the observed values is obtained. A positioning quality associated with the set of satellites is determined based on the set of residual values.

  • Publication number: 20090015995
    Abstract: A combinatorial keyboard structure with upright standing ability is disclosed, which comprises: a plurality of keypads, each being configured with at least a signal transmitting device, a first connecting mechanism being arranged at the bottom thereof, and at least a second connecting mechanism being arranged at a side thereof; and a base, being a plate-like element with a dented space formed therein; wherein, an upright standing keyboard unit is formed by connecting the first connecting mechanism of one of the plural keypads with that of another keypad, and thus an upright standing keyboard structure is constructed by sequentially connecting the second connecting mechanisms of more than one so-formed upright standing keyboard units from one to another while enabling the so-constructed upright standing keyboard structure to be fitted into the dented space of the base; and a keyboard structure is constructed by sequentially connecting the second connecting mechanisms of the plural keypads from one to another.

  • Patent number: 7331001
    Abstract: The present invention provides a test card for multiple functions testing. The test card includes a host of media devices, all of which reside on a single printed circuit board; and a selection device which selects each one of the host of media devices for testing. The test card can test all SD, MMC, MS (Pro), SMC devices and functions in one time in a bench without inserting and removing the media devices, thus accelerates the production line test speed.
