  • Publication number: 20240302880
    Abstract: A system is described that turns off a high power, power supply when a device no longer needs high power. A low power, power supply or a rechargeable battery provides power to determine when the device again needs high power. The low power supply consumes a minimum possible power when the device does not need high power and the power rechargeable battery is not charged. That is, the high power and low power, power supplies are turned on or off based on the real time power consumption need of the device and the charged state of the battery. The power need of the device is monitored by a current shunt monitoring circuit and a control signal monitoring circuit.

  • Patent number: 11809643
    Abstract: The functionality of a conventional mouse is extended to provide an extended number of simultaneously adjustable user interface parameters employing one or more user-removable modules. In an embodiment, a user interface for controlling an external device, such as a computer, includes a first user interface sensor configured with a housing. This first sensor generates a first plurality of signals responsive to movement of the housing relative to two orthogonal axes. A compartment is configured with the housing and is sized to receive the user-removable module. This user-removable module contains a second user interface sensor, which generates a second plurality of signals responsive to user manipulation. Output is provided responsive to signals generated by the first and second user interface sensors. In another embodiment, the housing of an extended functionality mouse itself serves as a module removable from a compartment provided in another physical device.

  • Patent number: 11290845
    Abstract: A location-based and preference-based system and method for matching media content about persons, places and things with the expressed preferences of mobile users to notify users about and provide users with access to media content about persons, places and things that match the user's expressed preferences. The system thus provides information such as stories or articles that match the user's interests and relate to their location. The system may assign ranks to all of the media content that meets that user's preferences wherein, in one embodiment, it will automatically play them in the assigned order. Comparison of the user's preferences with the various profiles of the media content allows the user only to be informed of the media content for those persons, places or things that the user is likely to be interested in. The system and method thus provides for a mobile real-time point of interest exchange network.

  • Patent number: 10616966
    Abstract: An apparatus, method and system are disclosed for providing AC line power to lighting devices such as light emitting diodes (“LEDs”). A representative apparatus comprises: a plurality of LEDs coupled in series to form a plurality of segments of LEDs; first and second current regulators; a current sensor; and a controller to monitor a current level through a series LED current path, and to provide for first or second segments of LEDs to be in or out of the series LED current path at different current levels. A voltage regulator is also utilized to provide a voltage during a zero-crossing interval of the AC voltage. In a representative embodiment, first and second segments of LEDs are both in the series LED current path regulated at a lower current level compared to when only the first segment of LEDs is in the series LED current path.
