  • Publication number: 20200191558
    Abstract: A fiber optic voltage conditioner, and method therefor, generally relate to voltage conditioning. In such a fiber optic voltage conditioner, there is a laser, and an optical circulator is coupled to receive a light signal from the laser. A controller is coupled to the laser and is configured to generate first control information for wavelength-drift control of the laser. A data acquisition module is coupled to the controller and is configured to generate second control information for the controller for adjustment of the first control information. A photodetector is coupled to the optical circulator to receive a returned optical signal and is coupled to the data acquisition module to provide an analog output signal thereto. The photodetector is configured to generate the analog output signal responsive to the returned optical signal. The data acquisition module is configured to generate the second control information using the analog output signal.

  • Patent number: 10575147
    Abstract: A system and method for controlling a mobile device at a headend includes the mobile device communicating a request for content to the headend. The headend requests geographic coordinate location data from the mobile device and, when geographic coordinate data is available, determines a first geographic region associated with the mobile device in response to the geographic coordinate location data. When geographic coordinate data is not available from the mobile device, the headend extracts an IP address from the request and determines a second geographic region based on the IP address and a confidence level. When the confidence level is below a threshold, the headend determines a third geographic region based on subscriber data for the mobile device. The headend controls the mobile device in response to one of the first geographic region, the second geographic region and the third geographic region.
