  • Patent number: 10651522
    Abstract: Disclosed is a hybrid electrochemical cell having two (or more) sub-cells each with different cell chemistry. For example, a second electrochemical sub-cell has a metal fuel electrode with the same type of metal fuel in a first electrochemical sub-cell, but has a different battery chemistry than the first sub-cell. A controller is configured to selectively generate an electrical current from at least one sub-cell in a discharge mode and selectively apply an electrical current to at least one sub cell in a charge mode, e.g., by controlling an open or closed state of switches. The operating modes may be controlled based on input parameters.

  • Patent number: 10244398
    Abstract: The capacity of a cellular wireless system is increased by operation of base stations or base station sectors arranged to re-use radio resource elements that are used by neighboring base stations or base station sectors, in conjunction with operation of relay stations, which are similarly arranged to re-use radio resource elements used by neighboring relay stations, and where the radio resource elements re-used by the relay stations are different to those used by the base stations. The relay stations provide coverage, particularly in the areas at the boundaries between the areas of coverage of base stations that suffer from interference between signals transmitted from the respective base stations. In addition, the relay stations generally increase the average available carrier to interference ratio compared with a system in which base stations alone are deployed.

  • Patent number: 10230238
    Abstract: A system includes a boost converter configured to amplify input voltage received from one or more power sources into output voltage. The system also includes a current sensor configured to sense a current of the input voltage for example, by induction. The system further includes a controller configured to adjust an amplification of the boost converter in response to the current sensed by the current sensor. When utilized in each of a plurality of power source modules coupled to a common load, the power source modules adjust the amplifications of their boost converters towards equalization of their output voltages and their currents in response to sensed currents of the input voltages changing through demand of the common load. Associated systems and methods are also disclosed.

  • Patent number: 10158389
    Abstract: A method of processing interference received in a wireless network, the interference comprising a non-linear product of at least one downlink signal of the wireless network, is provided. The method includes intercepting a plurality of optical links, each optical link being between a respective baseband processing unit of a plurality of baseband processing units and a respective radio head of a plurality of radio heads, to provide a plurality of downlink and uplink data streams. The method includes detecting interference in an uplink data stream representing signals received at a first uplink carrier frequency caused by non-linear products of at least a signal at a first downlink carrier frequency represented by a downlink data stream. The method includes generating an indication comprising information relating to an uplink carrier frequency experiencing interference and at least one downlink carrier frequency causing interference.

  • Publication number: 20170020119
    Abstract: An apparatus for capturing insects and allowing for their eventual release or cleaning of the apparatus is disclosed. The capture system allows for the safe and efficient capture of a variety of flying insects through the use of a natural attractant and a capture apparatus. The multi-part capture apparatus allows for easy cleaning, replenishment of the natural attractant, and release of the insects after capture. The multi-part capture apparatus also significantly reduces the ability of insect escape through the possible exit point.
