Use X4M05 UWB radar readings to recover voice from speaker vibration - GitHub - nesl/uwb_vibration_eavesdropping: Use X4M05 UWB radar readings to recover voice from speaker vibration

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).

The utility model reveals a UWB-to-Bluetooth device, and the device comprises: a UWB module which is in wireless communication with UWB terminal equipment; a Bluetooth module which is in wireless communication with Bluetooth terminal equipment; a microprocessor which is connected with the Bluetooth module and the UWB module; and a power module which supplies power to the device. The device provided by the utility model achieves the mutual communication between the Bluetooth equipment and the UWB equipment, solves a problem of communication between equipment and the UWB terminal, provides a convenient mode of communication to a user, and improves the additional value of an electronic product with a Bluetooth, wherein the equipment has the Bluetooth technology and does not have the UWB technology.

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. The UWB-based wireless bridge includes: a physical layer processing portion; a protocol converting block; a UWB signal transceiving portion; and a control portion.
