Locate and interact with nearby devices using identifiers, distance, and direction.

The Nearby Interaction framework makes it easy to integrate Ultra Wideband (UWB) in your apps and hardware accessories.

Some embodiments include a system, method, and computer program product for managing the Ultra Wideband (UWB) systems, especially when the UWB system is collocated with another wireless system (e.g., WiFi) to transmit and/or receive UWB signals with an occupied bandwidth (OBW) that satisfies a UWB OBW standard (e.g., a UWB OBW>=500 MHz.) In some embodiments a TailBit signal (e.g., a periodic signal at a selected frequency) is added to a UWB packet to generate frequency components at the selected frequency that enables the power spectrum of the TailBit UWB signal to satisfy the UWB OBW standard. In some embodiments an altered code sequence is used to generate an altered spread signal, where the altered code sequence reduces or removes a frequency component peak near DC frequency of the power spectrum of an altered UWB signal, resulting in altered UWB OBW that satisfies the UWB OBW standard.

This invention generally relates to ultra wideband (UWB) communication, and in particular to methods and apparatus for enabling such communicationWC 1 through a building, comprising generating a UWB signal and coupling the UWB signal to at least one electrical conductor of a mains power supply circuit of the building to distribute the UWB signal. This facilitates implementation of a UWB network with reduced interference. AlterWC 1native building wiring systems may be employed such as Cat 5 for computer networking or onWC 1e or two conducters of a telephone cable. The coupling may be direct or contactless such as capacitative coupling.

COPD is a progressive disease that may lead to death if not diagnosed and treated at an early stage. The examination of vital signs such as respiration rate is a promising approach for the detection of COPD. However, simultaneous consideration of the demographic and medical characteristics of patients is very important for better results. The objective of this research is to investigate the capability of UWB radar as a non-invasive approach to discriminate COPD patients from healthy subjects. The non-invasive approach is beneficial in pandemics such as the ongoing COVID-19 pandemic, where a safe distance between people needs to be maintained. The raw data are collected in a real environment (a hospital) non-invasively from a distance of 1.5 m. Respiration data are then extracted from the collected raw data using signal processing techniques. It was observed that the respiration rate of COPD patients alone is not enough for COPD patient detection. However, incorporating additional features such as age, gender, and smoking history with the respiration rate lead to robust performance. Different machine-learning classifiers, including Naïve Bayes, support vector machine, random forest, k nearest neighbor (KNN), Adaboost, and two deep-learning models—a convolutional neural network and a long short-term memory (LSTM) network—were utilized for COPD detection. Experimental results indicate that LSTM outperforms all employed models and obtained 93% accuracy. Performance comparison with existing studies corroborates the superior performance of the proposed approach.

A method and device for measuring biometric data using a UWB radar are disclosed. The disclosed method includes: (a) determining a respiratory rate by using reflection signals reflected off a target patient; (b) extracting respiration signals from the reflection signals, removing the extracted respiration signals from the reflection signals and converting into signals of a frequency domain; and (c) determining a heartbeat rate by detecting peak values from the frequency-domain signals converted in said step (b).

System and method for transparently attaching wireless peripherals to a computer using an UWB wireless network. A preferred embodiment comprises an interface (for example, interface 630 ), a communications bus (for example, a USB 620 ), and an UWB wireless network adapter (for example, an UWB transceiver 610 ). The interface translates messages from either the communications bus or the UWB wireless network adapter so that a software stack is not needed to perform the translation at a later time. This helps to maintain the computer's reliability and performance. The system and method also affords wireless connectivity without the presence of a computer system.

While ultra-wide band (UWB) technology has so far been presented by several chip companies as a technology for fine ranging applications, a Montreal, UWB tranceivers address needs of products like gaming peripherals and audio and AR/VR headsets, which would otherwise need to be wired to meet power and latency targets.

A UWB measuring device, in particular a hand-held positioning device, includes at least one signal-generating unit for generating at least one first UWB measuring signal, which is intended for a UWB measurement. The signal-generating unit is provided for generating a second measuring signal that differs from the first UWB measuring signal in at least one signal parameter. The second measuring signal is intended to detect a distance from an examination object and/or contact with the examination object.

An ultra wide band (UWB)-based wireless bridge converts wired serial data into a UWB signal with a quality of service, transmits it wirelessly, and inverts the UWB signal into wired serial data.
