Abstract: The present disclosure is directed to motion detection and recognition using segmented data from reflections of transmitted signals. An apparatus includes a transmitter, a receiver, and a processor. The processor may cause the transmitter to transmit pulses of an RF signal, the reflections of which are received by a receiver. For each of a number of consecutive segments, the transmitter may transmit N pulses of the RF signal, followed by quiet period. The processor may determine amplitude and phase data for reflections received by the receiver. Over a number of consecutive segments, the processor may detect and classify the amplitude and phase data change over time.

Abstract: An electronic device may include wireless circuitry with sensing circuitry that transmits radio-frequency sensing signals and receives reflected radio-frequency sensing signals. A mixer may generate a series of beat signals based on the sensing signals and the reflected sensing signals. The sensing circuitry may generate a beat phase based on an average of the series of beat signals, a set of phase values based on the series of beat signals, and a phase velocity based on the set of phase values. The sensing circuitry may resolve a phase ambiguity in the beat phase based on the phase velocity to identify a range between the electronic device and an external object. This way may allow the sensing circuitry to generate accurate ranges even in a low signal-to-noise ratio regime, such as when the external object is moving relative to the electronic device.

Abstract: A transceiver having quantization noise compensation is disclosed. The transceiver includes transmitter and receiver circuits. The transmitter is configured to receive and quantize a digital signal to generate a quantized signal. The quantized signal is then converted into an analog transmit signal and transmitted as a wireless signal. The receiver circuit is configured to receive a reflected version of the wireless signal and generate an analog receive signal based thereon. The analog receive signal is converted into a digital receive signal. Thereafter, the receiver cancels quantization noise from the digital receive signal to produce a digital output signal that can be utilized for further processing.

Abstract: Accuracy for detecting and tracking one or more objects of interest can be improved using radar-based tracking systems. In some examples, multiple radars implemented in a device can be used to transmit signals to, and receive signals from, the one or more objects of interest. To disambiguate an object of interest from undesired objects such as the hand of a user, the object of interest can include a transponder that applies a delay element to a signal received from a radar, and thereafter transmits a delayed return signal back to the radar. The delay produced by the delay element can separate the return signal from undesired reflections and enable disambiguation of those signals. Clear identification of the desired return signal can lead to more accurate object distance determinations, more accurate triangulation, and improved position detection and tracking accuracy.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a wireless device to perform sensing applications using communication signals. The first wireless device may determine to perform a sensing application and to perform the sensing application using a communication signal to be transmitted to a second device. In other words, the first wireless device may use a transmission that is scheduled for communication purposes to additionally perform sensing of one or more types. Example sensing or radar-like applications include estimating distance, motion, and/or angle to one or more objects or structures in the vicinity of the first wireless device. After transmitting the communication signal to the second wireless device, the first wireless device may receive a reflection of the communication signal. The first wireless device may use the reflection to perform the sensing application.

Abstract: An electronic device may include sensing circuitry that transmits radar signals and receives reflected signals over a set of antennas. Communications circuitry may use the antennas to transmit communications data subject to a maximum transmit power level. The sensing circuitry may generate Doppler information based on the reflected signals and may detect whether an external object is on a surface of the device based on the Doppler information. When the external object is detected on the surface, the external object is not within a hot-spot cone of the antennas and the communications circuitry may transmit the communications data without reducing the maximum transmit power level. When the external object is detected off the surface, the external object may be within the hot-spot cone and the communications circuitry may transmit the communications data with a reduced maximum transmit power level to satisfy regulatory limits on radio-frequency exposure or absorption.
