Abstract: To provide a novel and improved control device and storage medium capable of performing control based on a positional relation with higher accuracy.
A control device includes a control unit configured to perform control based on a presence area of a first communication device determined using a signal transmitted and received between the first communication device and at least one second communication device. The control unit performs control related to an operation of a controlled device in accordance with a second presence area when a first presence area determined based on a coordinate position of the first communication device on an arbitrary coordinate system associating the first communication device with the second communication device is inconsistent with the second presence area determined based on a distance between the first and second communication devices.

Abstract: In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. During a carrier acquisition mode of operation, the samples are continuously correlated with a predetermined preamble sequence to develop a correlation value. When the value exceeds a predetermined threshold, indicating that the preamble sequence is being received, estimates of the channel impulse response (“CIR”) are developed. When a start-of-frame delimiter (“SFD”) is detected, the best CIR estimate is provided to a channel matched filter (“CMF”). During a data recovery mode of operation, the CMF filters channel-injected noise from the sample stream. Both carrier phase errors and data timing errors are continuously detected and corrected during both the carrier acquisition and data recovery modes of operation. The phase of the carrier can be determined by accumulating the correlator output before it is rotated by the carrier correction. By comparing the carrier phases of two receivers separated by a known distance, d, the angle of incidence, θ, of the signal can be determined.

Abstract: Aspects of the present disclosure involve a system and method for performing radio frequency interferometry using optical fiber sensing. Optical fiber sensing is performed as a reference signal is defined and compared, in the optical domain, to incoming signals to obtain interference fringe patterns that can be used to decode phase shift offsets with respect to the designated reference signal. The phase shift offsets can be determined by first optically modulating the reference and incoming signals using a laser source as the carrier. In the optical domain, the reference and incoming signals are combined using an optical coupler and then converted back to the electrical domain for processing.

Abstract: A vehicle or other mobile communication entity (102) locates objects using received (typically radio frequency) signals (104, 106). These received signals included multi-path versions of the transmitted signals (104). The received signals may include packets having location information of the transmission source. The receiving vehicle may track, or know, its own position. The receiving entity may determine properties for a multi-path version of the signal (208, 210). These properties may include a delay, a Doppler and an angle of reception (122, 124) for one or more multi-path versions of the received signal. The receiving entity may also measure an imbalance (504) induced between a pair (or more) of antenna elements (302) for a particular multi-path version of the signal received. This imbalance may be dependent on the angle of arrival of the particular signal being received. In some embodiments of the invention, the measured imbalance includes two parts: a delta phase (dPhase, 400) and a delta Gain (dGain, 402). These delta values may be considered as a complex number with phase dPhase and magnitude dGain.
