  • Patent number: 10742473
    Abstract: A transmitter in a network transmits transmissions in accordance with an asymmetric signal constellation. A channel impairment in the network is detected. In response, a transmitter adjustment value for adjusting modulations at the transmitter is determined, the transmitter adjustment value determined to increase asymmetry of the asymmetric signal constellation. Signal acquisition may be improved by transmitting, at the transmitter, transmissions, based on transmitting using the determined transmitter adjustment value.

  • Patent number: 10436241
    Abstract: A snap-hook, including a hook and a dual-direction latch pivotally attached to the hook by a latch pin. The dual-direction latch blocks an opening to the hook's throat when held in a neutral position by a latch spring having a first spring force and a lever-return spring having a second spring force. The dual-direction latch is configured to move into the throat by overcoming the first spring force and to move out of the throat by overcoming the second spring force. The dual-direction latch comprises a spring guard attached to the dual-direction latch so as to shield the lever-return spring from coming into contact with one or both of an object disposed within a throat of the hook and an inner edge of the hook throat.

  • Patent number: 9396441
    Abstract: The invention is a method and system updating the automated responses of an autonomous system using sensor data from heterogeneous sources. An array of cases representing known situations are stored as data structures in a non-transitory memory. Each case in the array of cases is associated with an action to create a database of identifiable situation-action pairs. The system determines an acceptable range of correctness of partial matches of sensed data for new cases to the data properties of known cases and creates and overwrites now situation-action pairs in a process of autonomous learning of new responses.

  • Publication number: 20160033177
    Abstract: An air conditioning system that includes desiccant compartments for holding a desiccant; a heat exchanger, a blower and a vessel. The heat exchanger can be filled with a heat transfer medium, while the blower blows ambient air by the heat exchanger such that the blown air is cooled and the heat exchanger is warmed such that thermal energy increases and is transferred from the air to the heat transfer medium causing the heat transfer medium to turn into vapor. The vapor is then diffused to one of the desiccant compartments such that the vapor is adsorbed onto the desiccant creating a mixture. Then an energy source is applied to the mixture such that the vapor and desiccant are separated. The separated vapor is transported to the vessel where it is condensed and then sent back to the heat exchanger, such that the system is able to be continuously operating.
