  • Patent number: 10735127
    Abstract: A wavelength division multiplexing (WDM)-based photonic radar architecture is disclosed. The WDM-based photonic radar incorporates a WDM photonic input of N component wavelengths modulated by an IF-LFM input signal and its 90-degree phased counterpart. The modulated WDM photonic signal is split one branch sent to a photodetector for generation of an RF outbound signal and transmission of the signal, which is reflected by a target and received as an RF echo signal after a time delay. The other branch has each component wavelength time-adjusted by a second time delay for each wavelength. The resulting time-delayed WDM photonic signal is modulated again based on the received RF echo signal and split into wavelength selective channels. Filters in each channel extract two adjacent photonic signals converted to RF output signals by photodetectors. RF filters select a single RF signal for processing based on the closest difference between the two time delays.

    Abstract: In an example, a mobile device is configured to automatically lock when a detector, such as a GPS receiver, determines that the device is in motion above a certain speed threshold, such as 10 mph. Additional detectors may be used to determine whether the device is operated by the user or by a passenger, so that intelligent decisions can be made about whether to lock the device. During the lock, certain selected apps such as a GPS navigation system or music player may be enabled, with limited controls as appropriate. In some cases, hands-free operations may be available. The mobile device may also be configured to provide an automated response to incoming calls and messages.

  • Patent number: 9942715
    Abstract: Various embodiments include a method for regulating operation of mobile applications executing on a nomadic device. Signals for determining a speed of travel may be received at the nomadic device. The speed may be determined based on the one or more signals. If the determined speed exceeds a speed threshold, a speed restriction flag may be set and one or more functions of the mobile applications may be restricted. If, after setting the speed restriction flag, a speed cannot be determined, the application functions may be continually restricted until a speed can be determined.

  • Patent number: 9936466
    Abstract: Methods and systems are disclosed for managing the emission of data from RF enabled tags. In an example embodiment, data is emitted from a tag via RF communications. An operation can be implemented to detect one or more non-official applications running on a mobile device (e.g., a nearby mobile device). The emission power level for emitting such data can then be automatically varied until an answer is received from an official application running on another mobile device so as to prevent said mobile device running said non-official application from preventing said official application running on said another mobile device from completing a transaction with respect to said data emitted from said tag via said RF communications.

  • Patent number: 9681471
    Abstract: A device/object is paired to one or more communication devices for the purpose of activating and/or deactivating the device/object. Such activation of the device/object requires that the paired devices be in concurrent possession of the user (i.e., within a specified range of the user) and that, while in concurrent possession of the user, communicate information from the device/object to the communication device. Thus, the invention provides for additional security, in that two or more devices must in the possession of the user (or within the specified range of the user), and communicating with one another, in order for one of the paired devices to be in activated state.
