摘要： A wireless receiver system includes a receiver antenna, a sensor, a demodulation circuit, and a receiver controller. The sensor is configured to detect electrical information superimposed on an AC wireless signal. The demodulation circuit is configured to receive the electrical information from the at least one sensor, apply automatic bias control and gain control to generate modified electrical information, detect a change in the modified electrical information and determine if the change in the modified electrical information meets or exceeds one of a rise threshold or a fall threshold. If the change exceeds one of the rise threshold or the fall threshold, an alert is generated. Alerts are decoded into the electrical information.

摘要： Wireless power transfer systems, disclosed, include a wireless power transmission system and a wireless power receiver system. The wireless power transmission system includes a transmitter antenna configured to couple with a receiver antenna to transmit alternating current (AC) wireless signals to the receiver antenna. Antenna coupling may be inductive and may operate in conformance to a wireless power and data transfer protocol. A transmission controller drives the transmitter antenna at an operating frequency, and either the wireless power transmission system or the wireless power receiver system may damp the wireless power transmission to create a data signal containing a serial asynchronous data signal.

摘要： A method for transferring data between movable and stationary units of a linear transport system having a controller and linear motor with stator and rotor for driving the movable unit along a guide rail. The stator includes the stationary units, each with one or more drive coils. The rotor is arranged on the movable unit, with one or more magnets. The stationary units each have at least one stationary antenna, and the movable unit has a movable antenna. The controller selects a stationary antenna based on position data of the moveable antenna and outputs a data packet to the stationary unit, with control and data signals transmitted via the selected stationary antenna. The control signal includes identification information to identify the stationary antenna. The data signal includes a communication frame with a start bit and user data following a start sequence arranged to trigger data receipt of the movable unit.

摘要： A wireless communication system includes a first coupler having a first pair of electrodes and second coupler having a second pair of electrodes that at least partially oppose the first pair of electrodes. A transmission circuit applies a differential signal to the first coupler. A reception circuit receives a differential signal output from the second coupler based on electromagnetic coupling between the first coupler and the second coupler. A distance between centroids of the first pair of electrodes differs from a distance between centroids of the second pair of electrodes.
