Described embodiments include apparatus that includes a signal generator and an electric circuit. The signal generator is configured to supply a signal having both a first dominant frequency and a second dominant frequency. The electric circuit, which includes a reactive component, is configured to generate, upon the signal being supplied to the electric circuit, a magnetic field having both the first dominant frequency and the second dominant frequency, by virtue of the reactive component simultaneously resonating at both the first dominant frequency and the second dominant frequency. Other embodiments are also described.

A remote control device is provided that is configured for use in a load control system that includes one or more electrical loads. The remote control device includes a mounting structure and a control unit, and the control unit is configured to be attached to the mounting structure in a plurality of different orientations. The control unit includes a user interface, an orientation sensing circuit, and a communication circuit. The control unit is configured to determine an orientation of the control unit via the orientation sensing circuit. The control unit is also configured to translate a user input from the user interface into control data to control an electrical load of the load control system based on the orientation of the control unit and/or provide a visual indication of an amount of power delivered to the electrical load based on the orientation of the control unit.

Disclosed is a localizer system. The localizer system may be incorporated into a navigation system for tracking a tracking device. Generally, the localizer may include a transmitting coil array and a field shaping assembly.

An apparatus includes a sampling circuit to sample input from a sensor circuit. The input includes a cosine coil waveform and a sine coil waveform. The sampling circuit is to generate a cosine coil sampled data stream and a sine coil sampled data stream. The apparatus includes an adjustment circuit to, based upon a characterization of the sensor circuit, delay the cosine coil sampled data stream or the sine coil sampled data stream.

A geared motor is provided, including an electric motor, a transmission, a drive shaft and a switching device arranged on the drive shaft. The switching device includes a single housing that is distinct and separate from an electric motor housing and a transmission housing. The switching device also includes a contactless, absolute position-measuring device and an evaluation unit, each provided within the single housing, a gear wheel coupled to the drive shaft, and an output unit. The switching device is coupled to the position-measuring device by a pinion, which rotates about the same rotational axis as the drive shaft.
