  • Patent number: 10299095
    Abstract: Techniques of load modulation are described herein. A wireless power transmitting unit may include a resonator to periodically transmit a short beacon having a first time period. The wireless power transmitting unit also includes circuitry coupled to the resonator. The circuitry is configured to detect a load change in the resonator when transmitting the short beacon and cause the resonator to transmit a long beacon subsequent to said transmitting the short beacon if said load change is detected. The long beacon has a second time period longer than the first time period.

    Abstract: Techniques for powering up a wireless power receiving device are described herein. An example computing device includes a power receiving unit to wirelessly receive power from a power transmitting unit. The platform hardware includes a System on a Chip (SoC), a multicomm device, and a power sequence manager. The multicomm device is for wireless communication with two or more communication standards. One of the communication standards is used as a side channel for communicating with the power transmitting unit. The power sequence manager component manages activation of platform components of the platform hardware during a low battery cold boot condition. Upon detecting wireless power, the multicomm device is configured to automatically activate and the power sequence manager component is to suppress activation of other platform components of the platform hardware.

  • Publication number: 20160218569
    Abstract: Techniques of wireless power transmission are described herein. An example wireless power transmitting apparatus may include a coil and control circuitry.

  • Patent number: 9141560
    Abstract: A multi-level storage apparatus includes a first-level storage area to store first information, a second-level storage area to store second information, and a selectively enabled third-level storage area to store information based on different operational states. The third-level storage area stores the first information from the first-level storage area when the third-level storage area is to change from a first state to a second state. The first information in third-level storage area is transferred to the first-level storage area when the third-level storage area is to change from the second state to the first state. The first information is to include page miss information.

  • Patent number: 9043500
    Abstract: An electronic data tablet has a controller and transition manager. The controller is to store in a memory of the tablet virtual configuration space information for a peripheral device of a computer, and the transition manager is to control the controller to operate in a first mode and a second mode. The virtual configuration space information is stored in the tablet memory when the first mode is to be switched to the second mode. When the second mode is switched to the first mode, the virtual configuration space information is accessed to control recognition of the peripheral device of the computer without performing a re-scanning operation.

  • Patent number: 7636810
    Abstract: In one embodiment, a system includes a main memory including a compression cache to store uncompressed data, where the compression cache is organized as a sectored cache having on-die associated tags. On a tag match to an associated tag, a hit signal is sent to a memory controller coupled to the main memory to schedule an uncompressed data access from the compression cache. A compressed memory may be present to store a plurality of compressed data. Also, a higher priority may be assigned to read operations of the compressed memory in comparison to other operations to the compressed memory. Other embodiments are described and claimed.
