Abstract: A double-balanced mixer, including a coupling transformer, a first diode cascade circuit, a second diode cascade circuit, and a first set of coils, is provided. The coupling transformer receives a first input signal and generates at least one set of signals with opposite voltage phases. The first diode cascade circuit is coupled to the coupling transformer, and generates a first node voltage according to a first set of bias voltages. The second diode cascade circuit is coupled to the coupling transformer, and generates a second node voltage according to a second set of bias voltages. The first set of coils is coupled to the first and second diode cascade circuits, receives the first and second node voltages and a second input signal, and generates an output signal.

Abstract: A circuit for detecting motion of an object in an environment. The circuit comprises a transmission chain, an envelope extraction circuit, and a detector circuit. The transmission chain includes a power amplifier, a sensing circuit, and a single antenna. By the single antenna, a first wireless signal related to a transmission signal is transmitted. The transmission signal is a continuous wave signal. The single antenna can receive a second wireless signal as an incoming signal. The second wireless signal is a reflected first wireless signal from the object. The sensing circuit can obtain a modulation signal by combining the continuous wave signal and the incoming signal. The modulation signal contains a Doppler shift caused by the motion of the object. The envelope extraction circuit can extract a signal envelope from the modulation signal. The detector circuit can determine the motion of the object according to the signal envelope.

Abstract: An occupancy detection apparatus has a switch, a first antenna, a second antenna, a transmitter, and a motion detection circuit. The occupancy detection apparatus monitors for a first motion in a first region using the first antenna using a first motion detection parameter. When no first motion is sensed by the monitoring using the first antenna, the occupancy detection apparatus monitors for a second motion in a second region using the second antenna using a second motion detection parameter. When no second motion is sensed by monitoring using the second antenna, the occupancy detection apparatus designates a space, which encompasses the second region, as unoccupied. The first region and the second region overlap one another, and the first motion detection parameter is different from the second motion detection parameter.

Abstract: A motion detecting system includes a microwave motion sensor and an MCU. After detecting a motion with a first configuration, the microwave motion sensor is configured to operate with a second configuration for detecting another motion. The MCU is configured to operate in different modes for performing corresponding actions based on whether the microwave motion sensor can detect motions with different configurations, thereby reducing power consumption. The present motion detecting system can determine the type of motions detected by the microwave motion sensor, thereby reducing the false alarm rate.

Abstract: A Doppler motion sensor device is used for detecting a motion of an object. The Doppler motion sensor device includes a first antenna and a second antenna. The first antenna is used to transmit or receive a first wireless signal. The second antenna is used to transmit or receive a second wireless signal. A first straight line passing through a first feed-in point and a first middle point of the first antenna is orthogonal to a second straight line passing through a second feed-in point and a second middle point of the second antenna. One of the first wireless signal and the second wireless signal is a transmission signal. The transmission signal is reflected by the object to form the other one of the first wireless signal and the second wireless signal.
