Abstract: Wireless power transmission to downhole well installations is provided using acoustic guided Lamb waves and a tubular conduit (production tubing, casing) as the power transmission medium. A phased array of acoustic transmitters is present at the transmitting end (surface) and an array of acoustic receivers at the receiving end (downhole). Both transmitter and receiver arrays are coupled to the tubular conduit. Beamforming techniques are used along with power amplifiers to generate directional, high power and low frequency acoustic guided Lamb waves along the wellbore to transmit power over long distances. A downhole multi-channel acoustic energy collecting system receives the transmitted acoustic signal, and generates electrical power and stores the power in downhole electrical power storage. This power is used to operate downhole well equipment including sensing, control and telemetry devices.

Abstract: An electronic lockbox system allows both sales agents and sales prospects to communicate either with the lockbox, or with the central clearinghouse computer. Contextual data then is provided to the sales prospect while the prospect is visiting a specific property that is the site of a lockbox installation. Both the agent and the prospect use smart devices, such as smart phones, that have both wide area network capability and low power radio capability. In other situations, contextual data can be sent to a user having a smart device, in which that contextual data pertains to at least one human occupant of the specific property where that lockbox has been installed, which can be useful where a medical caregiver arrives to visit a human occupant of a specific property that is protected by the electronic lockbox.

Abstract: Receiving short message service (SMS) messages and providing a response report based at least in part on the received SMS message is disclosed. A user equipment (UE) may receive an SMS message via a communications link between the UE and a mobile communications network. The UE may be configured to determine if the SMS message was received with or without error. Based at least in part on this determination, the UE may generate the response report to provide to the mobile communications network. The UE may further identify that the communications link between itself and the mobile communications network may be severed. As a result, the UE may reestablish the communications link with the mobile communications network and then transmit the response report.
