Devices, systems, and techniques are described to detect when a power transmitting and receiving system is in an inefficient position, which may cause a thermal response that less desirable than a more efficient position. The system may power transmitting device configured to wirelessly transfer electromagnetic energy to a power receiving device. Processing circuitry of the system may compute a target output power deliverable by the power transmitting device for a first duration and control the power transmitting device to output the target output power based in part on a heat limit. The processing circuitry may further calculate an energy transfer efficiency to the power receiving unit, update an adjustment factor based on the calculated energy transfer efficiency, and apply the adjustment factor to the heat limit for a subsequent duration.

Implant location detection and adaptive temperature control

Systems and methods for improved wireless recharging efficiency and decreased processing requirements are described. A plurality of duty cycle/input voltage pairs are stored in a recharger, corresponding to three subsets: a first subset corresponding to a constant minimum input voltage and an increasing duty cycle; a second subset corresponding to a constant duty cycle and an increasing input voltage; and a third subset corresponding to a maximum input voltage and an increasing duty cycle.

A payload launch system includes a launch tube, payload, rocket tube, pressurized motor assembly, and control system. The motor assembly has a launch actuator and an accumulator housing containing compressed gas. The accumulator housing defines a vent opening having a closure. The control system transmits an actuation signal to the actuator in response to a launch request signal to open the closure and cause a discharge of pressure into the launch tube. This causes the rocket tube to launch from the launch tube to a threshold altitude in a single gaseous thrust phase. A method includes deploying a launch system, transmitting a launch actuation signal to the launch actuator via a control system, and opening a closure to allow compressed gas to enter the launch tube, thereby launching the rocket tube from the launch tube to a threshold altitude in the single gaseous thrust phase.

Payload launch system and method

A store and forward receiver for a satellite communication system employs a multi-threaded command interpreter, and an associated reduced complexity audio control language (ACL) to define commands for controlling actions at different receiver sites, each of which is programmable for its own local programming purposes. Upon receipt of a relatively simple command from the headend, the interpreter accesses and executes an associated sequence of potentially locally unique, previously stored commands, causing performance of a sequence of actions, e.g., play back of potentially locally unique, previously stored information files, interleaved with portions of a headend-source commercial audio program being rebroadcast at the receiver site. This allows different affiliate stations to produce separate potentially locally unique complex sequences of actions from a single headend-sourced command for all receivers in a network grouping.
