  • Patent number: 10447150
    Abstract: A method for maintaining reliability of a distributed power system including a power converter having input terminals and output terminals. Input power is received at the input terminals. The input power is converted to an output power at the output terminals. A temperature is measured in or in the environment of the power converter. The power conversion of the input power to the output power may be controlled to maximize the input power by setting at the input terminals the input voltage or the input current according to predetermined criteria. One of the predetermined criteria is configured to reduce the input power based on the temperature signal responsive to the temperature. The adjustment of input power reduces the input voltage and/or input current thereby lowering the temperature of the power converter.

  • Patent number: 9461644
    Abstract: An electronic switch, or an electronic equipment having such switch that has a tap-sensing detection region for a user to perform finger-tapping, foot-tapping, or other finger movements on a contact surface in this region and effectuate sending of a signal to turn on, turn off, or perform other contemplated functions of the electronic equipment. This switch emits a radiation, such as infrared light, towards the detection region. The reflection of the radiation off of an object is collected and compared to a predetermined value. If there is a match, the switch would send a signal to the device to perform the predetermined function. In operation, the switch would allow an electrical equipment to have a “virtual switch” where the user can control the device by manipulating his finger or his foot in the designated detection region. The equipment may optionally have a LED illuminator to shine a lit marking indicating where the contact surface is and how it is to be used.

  • Patent number: 9460448
    Abstract: A system for remote monitoring of environmental conditions at a site and transmitting alerts to interested parties' mobile devices via a social networking service is described. The system employs a wireless communications device, partially exposed outside a small, metal enclosure, to transmit SMS (text message) alerts to a social networking site. Interested parties, including other devices, receive the alerts by simply subscribing to the ‘user’ device. Thus, no configuration of the device by interested parties is required. Temperature alerts are generated by the device without user-configured or fixed thresholds. A wall-mounted installation of the device conceals the external antenna within the wall cavity.

  • Patent number: 9444281
    Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for providing a charger capable of adaptively handling a range of power inputs. The charger can selectively activate different control switches within the charger in order to more efficiently use current supplied to the charger. When a low power input is provided to the charger, the charger can reduce the number of active control switches being used to provide a voltage output from the charger. In this way, the capacitance required to toggle the control switches can be reduced. When a high power input is provided to the charger, the number of active control switches can be increased in order to increase a total amount of charge that can be provided from the charger, thereby reducing charge times for batteries.

  • Patent number: 9441869
    Abstract: A circuit allows an energy efficient DC design to drop in to an AC application and interface directly with the AC signals in a cost effective manner. The circuit is implemented without any use of mechanically switched contacts. All switching of current is done through solid state devices. Positional feedback and speed of the motor is provided through an optically encoded output gear eliminating the need for mechanical position switches to determine motor rotational position.
