Gerald CAVANAUGH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9521512
    Abstract: In one embodiment, a system determines a designated wireless device lacks a fixed geographic location, and uses the determination that the designated wireless device lacks a fixed geographic location to improve location estimates. The system determines one or more neighboring wireless devices have relationships with the designated wireless device, wherein a relationship is established when wireless signals from a neighboring wireless device and the designated wireless device are detected by a same receiver. A measure of likelihood is calculated that the designated wireless device lacks a fixed geographic location based at least in part on a number of the relationships or a duration of the relationships. Based on the measure of likelihood, the designated wireless device is excluded from being used in the wireless positioning system as a beacon for estimating the location of a client device.

  • Patent number: 9014715
    Abstract: Systems for and methods of determining likelihood of atypical transmission characteristics of reference points in a positioning system are disclosed. A method of determining a measure of likelihood that a designated wireless device exhibits signal transmission characteristics atypical of a wireless device of a type matching the designated device includes determining reference points associated with the designated device, which are a geographic position at which signals from the designated device were detected and/or another wireless device from which signals were also detected by a receiver within a selected period of time during which the signals from the designated device were detected.

  • Patent number: 8996032
    Abstract: Systems for and methods of determining likelihood of reference point identity duplication in a positioning system are disclosed. A method of determining a measure of likelihood that a designated identifier is shared by wireless devices includes determining reference points associated with any wireless device having a designated identifier. The reference points are a geographic position at which signals from any of the wireless devices were detected and/or wireless devices from which signals were also detected within a selected period of time during which the signals from any of the wireless devices having the designated identifier were detected. The method also includes determining statistical information about a temporal distribution of detection of signals of reference points, a spatial distribution of the reference points, and/or a cardinality of the reference points and determining a measure of likelihood that the designated identifier is shared by wireless devices is based on the statistical information.

  • Patent number: 8983504
    Abstract: Systems for and methods of determining likelihood of relocation of reference points in a positioning system are disclosed. A method of determining a measure of likelihood that an estimated geographic location of a designated wireless device is not its accurate present location includes determining a set of reference points associated with the device, which are a geographic position at which signals from the device were detected and/or other devices having a relationship with the designated device. The existence of the relationship is based on the devices being within signal reception range of a same position within a selected period of time. The method includes retrieving attributes of the reference points and/or of the relationships and determining a measure of likelihood that an estimated geographic location associated with the designated device is not its present location based on the attributes of the reference points of the set and/or of the relationships.

  • Patent number: 8971923
    Abstract: Methods of and systems for measuring beacon stability of wireless access points are provided. A method of determining a measure of likelihood that a designated wireless device exhibits at least one pathological characteristic includes determining a set of reference points associated with a designated wireless device, and retrieving attributes of the reference points, attributes associated with other wireless devices related to the designated wireless device, and/or statistical information. The statistical information includes a temporal distribution of detection of signals of reference points, a spatial distribution of the reference points, and/or a cardinality of the set or a subset of the reference points. The method further includes determining a measure of likelihood that the designated wireless device exhibits at least one pathological characteristic based on attributes of the reference points, attributes associated with the reception of signals, and/or the statistical information.

  • Patent number: 8971915
    Abstract: Systems for and methods of determining likelihood of mobility of reference points in a positioning system are disclosed. A method of determining a measure of likelihood that a designated wireless device is a mobile device includes determining a set of reference points associated with a designated wireless device. The reference points are a geographic position at which signals from the device were detected and/or another wireless device from which signals were also detected by a receiver within a selected period of time during which the signals from the designated device were detected. The method also includes retrieving statistical information about a temporal distribution of detection of signals of reference points, a spatial distribution of the reference points, and/or a cardinality of the reference points. The method includes determining a measure of likelihood that the designated wireless device is a mobile wireless device based on the statistical information.
