  • Patent number: 10165124
    Abstract: Automatically transferring transmissions of a data network in which one or more processors receive metrics of active concurrent transmission sessions on a LAN that includes a data network, connected to a WAN, and a threshold level of concurrent transmission sessions of the data network of the LAN. Receiving a request for an additional transmission session, and responsive to determining that the threshold level of concurrent transmission sessions is exceeded, accessing data that maps a communication connection of the data network for a targeted recipient, to a communication connection of an alternate network corresponding to the targeted recipient, and performing a transfer of the additional transmission session from the communication connection of the data network for the targeted recipient, to the alternate network corresponding to the targeted recipient.

  • Patent number: 5631540
    Abstract: A highly accurate apparatus and method of predicting remaining capacity Q and reserve time t of a discharging battery to a selected end voltage is determined by an arrangement considering the open circuit voltage, battery voltage, battery temperature and its internal resistance. The remaining battery capacity Q is determined from the difference between the battery full charge open circuit voltage Eoc and the voltage loss due to the internal resistance of the battery IRint and the battery voltage on discharge divided by the battery temperature T, which is the temperature-corrected battery overvoltage.

  • Patent number: 5623195
    Abstract: A battery charging system controls and modifies the output voltage of the charging rectifier in response to differing temperature ranges of the battery. At a low range of temperatures starting at a low temperature (e.g. within a range of 0 to 25.degree. C. to about 53.degree. C.) the rectifier voltage decreases as the temperature increases to prevent charging current from rising as the battery temperature increases. This change is performed in accord with a linear graphical slope relating the change of charging voltage to temperature. A suitable charging voltage decrease rate may be 3 mV/.degree. C./cell with a range of 1.5 mV/.degree. C./cell to 5 mV/.degree. C./cell being acceptable. Reduction of the charging voltage within this range reduces the aging effect of high temperature operation of the battery. The charging voltage applied to the battery is held at a constant value over a subsequent range of temperatures (e.g. 53.degree. C. to 75.degree. C.

  • Patent number: 5271916
    Abstract: A method and apparatus for selectively oxidizing carbon monoxide in a hydrogen rich feed stream. The method comprises mixing a feed stream consisting essentially of hydrogen, carbon dioxide, water and carbon monoxide with a first predetermined quantity of oxygen (air). The temperature of the mixed feed/oxygen stream is adjusted in a first the heat exchanger assembly (20) to a first temperature. The mixed feed/oxygen stream is sent to reaction chambers (30,32) having an oxidation catalyst contained therein. The carbon monoxide of the feed stream preferentially absorbs on the catalyst at the first temperature to react with the oxygen in the chambers (30,32) with minimal simultaneous reaction of the hydrogen to form an intermediate hydrogen rich process stream having a lower carbon monoxide content than the feed stream. The elevated outlet temperature of the process stream is carefully controlled in a second heat exchanger assembly (42) to a second temperature above the first temperature.

  • Patent number: 4967765
    Abstract: A urethral inserted applicator for prostate hyperthermia includes a multi-tube, balloon type catheter. The catheter includes first and second closed end fluid dry tubes, respectively, for a helical coil antenna type applicator, and a microwave type temperature sensor for measuring the temperature of the prostate tissue, and an open fluid receiving tube. A microwave generator supplies electromagnetic energy to the applicator. A comparator is connected to the temperature sensor and a temperature reference potentiometer for comparing the actual tissue temperature level with a desired temperature level and outputting control signals to the microwave generator for controlling the output to the applicator. The coil type applicator is an elongated coil having a tip end connected to the center conductor of a coaxial cable and an opposite end connected to the outer conductor of the coaxial cable.
