  • Publication number: 20250024254
    Abstract: A secure ranging method and an apparatus are provided. The method includes: a receiving-end device and a transmitting-end device obtain a session key through a narrowband system. The devices of both parties further generate secure CTSs in a symmetric manner based on the session key in combination with CTS configuration information, and perform inter-device ranging in a UWB system by using the CTSs. According to this application, the CTS can be flexibly configured based on the CTS configuration information, to improve secure ranging performance. In addition, the narrowband system replaces the UWB system to perform key-related information negotiation, and ranging is performed in the UWB system, so that high-accuracy ranging is implemented while low power consumption is considered.

  • Patent number: 12175968
    Abstract: Techniques for selecting a skill to execute in response to a natural language input are described. A system may receive a natural language input, determine profile data associated with the natural language input, and determine the profile data indicates a locale and at least first language and second languages. The system determines first and second sets of skills corresponding to the locale/first language and locale/second language, respectively. The system determines a first group of skill candidates corresponding to a portion of the first set of skills, and determines a second group of skill candidates corresponding to a portion of the second set of skills. The system performs ranking processing across the first and second groups of skills to determine a best skill for responding to the natural language input. Thus, in some situations, the skill invoked may not correspond to the same language represented in the natural language input.

  • Patent number: 11716150
    Abstract: An optical receiver capable of substantially measuring the phase and amplitude of a received intensity- or amplitude-modulated optical signal by performing digital-signal processing. In an example embodiment, a DSP of the receiver operates to reduce the detrimental effects of relative phase noise between the optical reference oscillator and optical carrier based on an optical pilot present in the received optical signal. The DSP may employ a sequence of digital filters configured to select a signal component that represents a non-vestigial modulation sideband and then perform signal equalization thereon. The signal equalization may include but is not limited to dispersion compensation. In some embodiments, the optical receiver can be a direct-detection optical receiver. In an example embodiment, the optical reference oscillator and optical carrier are generated using two respective independently running lasers that may or may not be co-located.
