Wireless communication between two electronic devices may be used to determine a distance between the two devices, even in the presence of an otherwise-disruptive attacker. A wireless receiver system of one device may receive a true wireless ranging signal from a first transmitting device and a false wireless ranging signal from an attacker. The wireless receiver system may correlate the wireless signals with a known preamble sequence and perform channel estimation using the result, obtaining a channel impulse response for the wireless signals. The wireless receiver system may filter the channel impulse response for the plurality of wireless signals by removing at least part of the channel impulse response due to the false wireless ranging signal while not removing at least part of the channel impulse response due to the true wireless ranging signal. The receiver system may perform a wireless ranging operation using the filtered channel impulse response.

An extended reality headset has light-based communication transceivers coupled to the extended reality headset. The relative position of a remote transceiver with respect to the current position and orientation of the extended reality headset is determined. A line-of-sight is calculated from the light-based communication transceivers to the remote transceiver. The light-based communication transceivers emit a light-based communications beam in accordance with the calculated line-of-sight. The light-based communications beam is adjusted in response to changes to the relative position of the remote transceiver with respect to the current position and orientation of the extended reality headset.

Optical over-the-air peer to peer communication for XR devices

Metallic, electrically conductive, structures on smart glasses, which can be utilized to provide structural integrity and/or thermal dissipation capability, can be leveraged to provide antenna capability as well. Metallic structures on smart glasses are utilized as antenna grounds, with corresponding antenna elements being electrically coupled thereto, and located on the glasses temple. Such antenna elements implement folded antennas having an antenna length selected in accordance with desired communicational frequencies. A shorting pin establishes the electrical connection to the antenna ground. Metallic structures on smart glasses are also utilized as antenna elements, with different metallic structures acting as the antenna ground. Such antenna elements implement monopole antennas having a length selected in accordance with desired communicational frequencies, and a width that can maintain structural integrity and/or thermal dissipation capability. Multiple antenna elements are manufactured onto a single glasses temple, and both temples of the smart glasses comprise antennas.

A system for facilitating secure communications accesses a secure element in response to determining that an authorized user operates the system. The system causes a light emitter to emit an output light signal for detection by a second system. The output light signal is emitted according to a predefined field of view, which operates as a constraint to prevent devices outside of the field of view from detecting the output light signal. The system also configures the light detector to detect a second output light signal emitted by a second light emitter of the second system. In response to (i) detection of the output light signal by a second light detector of the second system and (ii) detection of the second output light signal by the light detector, the system enables secure communication between the system and the second system.

A schedule of the first piconet includes a plurality of slots associated with an audio packet, a first subset of the slots used by the source device to transmit the audio packet, the first and second wireless audio output devices tuning to the first piconet to listen for the transmissions of the audio packet, and when, after a last one of the first subset of slots, the first or second wireless audio output devices did not receive the audio packet, the first and second wireless audio output devices exchange information via the second piconet such that the both wireless audio output device receive the audio packet.

Real-time relay of wireless communications

Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Embodiments are disclosed for terahertz spectroscopy and imaging in dynamic environments. In an embodiment, a transmitter of an electronic device emits a continuous electromagnetic (EM) wave in the terahertz (THz) frequency band into a dynamic environment that includes a transmission medium that changes over time. A receiver of the electronic device, receives an EM wave reflected off an object in the environment and determines a spectral response of the reflected EM wave. The spectral response includes absorption spectra at a frequency in the THz frequency band that is indicative of a known target transmission medium. The absorption spectra of the target transmission medium and a path length of the reflected EM wave signal are used to obtain the concentration level of the target transmission medium from a reference library of known concentration levels.

Terahertz spectroscopy and imaging in dynamic environments

A technique for reducing interference on conducted RF links involves a determination of active wireless channels in an electronic device. For example, the device can determine whether there are any active cellular, WiFi, and/or Bluetooth channels. If so, any active channels can be removed from a list of possible channels that can be used for generating the RF signals for the conducted RF link. If any idle channels remain available, one or more may be selected for use for the conducted RF link. Those idle channels having a higher offset from any active channels may be given a greater weight in the selection since they should be less likely to be subject to interference. If not, one of the least crowded active channels may be selected for use for the conducted RF link.
