  • Patent number: 9570918
    Abstract: A wireless power transfer system is disclosed that allows for directed power distribution. A power station that transmits the power can also transmit a distribution instruction that authorizes and/or prohibits various systems/components within a receiver device to receive power. A manager and power router within the receiver device route the power as directed by the distribution instruction. When multiple components/systems are authorized to receive the power, the receiver device can monitor power need and route as needed between authorized components/systems. In addition, the receiver device can act as a transmitter to wireless flash power to another device. The flash consists of bursting a large amount of power over a relatively short time. Several constraints, configurations, and considerations are required to perform this function.

  • Patent number: 9504003
    Abstract: Embodiments provide an indoor position system that can be used by an mobile device (legacy or non-legacy) without changes at the mobile device. In an embodiment, to use the indoor position system, a user of the mobile device downloads an application to the mobile device, which interfaces with the mobile device's existing wireless radio technology circuitry or module (e.g., WLAN chip) to obtain the position of the mobile device. In one embodiment, the indoor position system includes a plurality of wireless anchors with known positions that are each configured to receive a packet transmitted by the mobile device, time-stamp the packet per the arrival time of the packet, and forward the time-stamped packet to a pre-defined site. At the pre-defined site, the position of the mobile device is computed and sent to the application running on the mobile device.
