  • Patent number: 11641563
    Abstract: Embodiments described herein provide for system and methods to crowdsource the location of wireless devices and accessories that lack a connection to a wide area network. One embodiment provides for a data processing system configured to perform operations comprising loading a user interface on an electronic device, the user interface to enable the determination of a location of a wireless accessory that is associated with the electronic device, generating a set of public keys included within a signal broadcast by the wireless accessory, the signal broadcast during a first period, sending the set of public keys to a server with a request to return data that corresponds with a public key in the set of public keys, decrypting the location data using a private key associated with the public key, and processing the location data to determine a probable location for the wireless accessory.

  • Patent number: 8824990
    Abstract: There is provided a method for use in a wireless communication to avoid detection of a false modulated signal in a paged device. In one embodiment, a modulated signal is received by the paged device. Then, the modulated signal is identified by the paged device as a preliminary false modulated signal. Thereafter, the gain of at least one paged device amplifier and/or a matching threshold of the paged device is reduced by the paged device to decrease a sensitivity of the paged device to avoid detection of a future false modulated signal. In one embodiment, the wireless communication is a Bluetooth wireless communication and the paged device is a Bluetooth enabled device. An exemplary system for implementing one embodiment of the disclosed method is described.

  • Patent number: 8457554
    Abstract: Methods and systems for wireless communication are disclosed and may include controlling one or more scans of a received signal detection frequency across a frequency range and storing a magnitude of the received signal at each frequency where the magnitude exceeds a threshold level. A type of one or more signals in the received signal may be determined based on a bandwidth of the signals. A Bluetooth page/inquiry scan may be initiated if the determined type is a page/inquiry signal, and scans may be continued if the determined type may not be a page/inquiry signal. The scans may be repeated on a periodic basis and may be controlled utilizing a voltage controlled oscillator. Each of the scans may include a plurality of discrete frequency steps or a continuous frequency ramp. The controlling may include a start frequency, an end frequency and a frequency step size for the scans.

  • Publication number: 20090022208
    Abstract: Methods and systems for wireless communication are disclosed and may include sweeping a signal detection frequency one or more times across a plurality of steps in a frequency range. The measured signal strength at each step may be compared to a threshold, and a status may be stored, which may depend on the presence of a measured signal strength above threshold. The detection frequency may be swept utilizing a voltage controlled oscillator, which may be tuned via a control voltage and/or calibration capacitors. Steps may be skipped when a measured signal strength may be greater than the threshold, and may occur after multiple above threshold measurements. The steps may have variable frequency width, and the range may include the Bluetooth band from 2.40 GHz to 2.48 GHz. The frequency may be swept over a subset of the Bluetooth band, and may be swept on a periodic basis.
