摘要： A location system includes transmission reception devices. A first transmission reception device is configured to operate as a stationary unit of the location system for localizing tag devices by exchanging ultra-wideband signals. The tag devices is localizable within a localizing space that extends along a high-resolution line associated with the first transmission reception device. The system also includes a movable unit and first and second tag devices that are positioned at the movable unit and are separated from each other by a tag separation distance. A control system is configured to perform an ultra-wideband signal analysis to determine the distance from a selected tag device to the first transmission reception device and to derive an orientation of the movable unit with respect to the high-resolution line from distances determined for the first tag device and the second tag device.

摘要： The present disclosure relates to a frequency synthesizer capable of generating a full spectrum for ultra-wideband applications by utilizing a single voltage-controlled oscillator (VCO). The disclosed frequency synthesizer includes a phase-frequency detector (PFD), a charge pump (CP), a VCO, a feedback divider, and a divider bank. The PFD, the CP, the VCO, and the feedback divider are coupled in series in a closed loop, while the divider bank follows the VCO and is not included in the closed loop. Herein, the VCO has a tuning range less than 35%. The divider bank includes two or more divider branches parallel to each other, each of which is configured to provide a different division ratio. An oscillating spectrum of the VCO and division ratios of the two or more divider branches are selected such that the divider bank is capable of providing a continuous spectrum with at least a 64% frequency coverage.

摘要： 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.-

摘要： A method of generating an impulse for impulse radio transmission signals and an impulse-radio ultra-wideband transmitter are provided. In one aspect, the method includes distributing input digital data according to time information data and amplitude information data along a first modulation path and a second modulation path, respectively. Pulse position modulation is performed based on the time information data along the first modulation path to define a timing position of the impulse. Pulse amplitude modulation is performed based on the amplitude information data along the second modulation path to define an envelope of the impulse. The input digital data can be distributed according to phase information data along a third modulation path, and phase shift keying modulation can be performed based on the phase information data along the third modulation path to define a phase of a carrier signal of the impulse.

摘要： An interactive system includes a portable device configured to be used in an interactive environment. The portable device includes an input mechanism that initiates delivery of a virtual projectile. The interactive system also includes a control system that includes one or more processors. The one or more processors receive data indicative of a location and an orientation of the portable device and receive additional data indicative of actuation of the input mechanism. In addition, the one or more processors determine a successful virtual interaction of an interactive physical element with the virtual projectile based on the location and the orientation of the portable device during the actuation of the input mechanism, and adjust an interactive virtual element displayed on a display screen in response to the successful virtual interaction of the interactive physical element.

摘要： A UWB localization device comprising a UWB receiver with a first and second antenna device for receiving UWB signals from a UWB transmitter; a UWB shield arranged between the antenna devices; and a processing unit. The processing unit is configured to determine, by processing properties of the UWB signals, a first and a second time of arrival of UWB signals from a UWB transmitter at the first and second antenna devices; and to determine a location of the UWB transmitter based on the first and second time of arrival. The UWB shield is configured to cause a delay in the second time of arrival of UWB signals from the UWB transmitter received at the second antenna device. The first and the second antenna devices are arranged with opposing antenna sensitivity patterns.
