Abstract: An indoor positioning system comprises at least one signal source disposed in an indoor environment having training points, and storage and positioning devices coupled with each other. The signal source has power levels, based on one of which it transmits a wireless signal. The storage device stores for each training point a first signal strength, and for at least one adaptation point among the training points a second signal strength.

Abstract: A lighting-dimming device has a dimming module with an encoding function and at least one light module with a decoding function and controlled by the dimming module. The dimming module is designated with a required brightness and address command by a user. A triode AC switch of the dimming module is controlled to chop a power based on the required brightness and address command. The chopped power is transmitted to the light module to control the brightness of the light module. In the chopped power, only a part of cycles of the power is chopped and most of the power waveforms are maintained. Therefore, a high power factor is maintained.

Abstract: A digitized FM (frequency modulation) stereo multiplexing circuit for an FM stereo transmitter has a digital audio I/O interface, a digitized FM stereo multiplexing circuit, a low-pass filter and an FM circuit. When a digital audio data is inputted, a digital audio decoder decodes the digital audio data to acquire left and right channel audio signals. The left and right channel audio signals are inputted to an over-sampling unit circuits to process sampling and then to output to an FM stereo multiplexer. The FM stereo multiplexer then generates a master signal and a secondary signal by processing the sampled left and right channel audio signals. In the meanwhile a switch signal and a pilot signal are acquired with an address counter to output from a memory unit. Then the master signal, the secondary signal and the pilot signal are combined as the digital FM stereo data.

Two switching stages are each formed by four CMOS transistors connected in series, with one end of the circuit being connected to a positive power supply with a higher voltage and another end connected to ground or negative power supply terminal. The switching stages are able to produce high output voltages, which are applied on the gates of the CMOS transistors in the driver stage to lower the driving impedance of the conduction channel and to produce sufficient output current to drive a DC motor.
