  • Isolated high voltage battery charger and integrated battery pack
    Patent number: 7253584
    Abstract: Methods and apparatus are provided for charging a high-voltage battery of a hybrid electric vehicle. The high-voltage battery charging apparatus comprises a battery charger configured to provide electrical energy, a battery module configured to store the electrical energy provided by the battery charger, and a high-voltage bus coupled to the battery charger and the battery module, which is configured to transmit the electrical energy from the battery charger and battery module to the electrical system of the hybrid electric vehicle. In addition, the high-voltage battery charging apparatus comprises a bus contactor interposed between the high-voltage bus and the battery charger, which is bus contactor configured to provide a first substantial electrical isolation between the battery charger and the high-voltage bus during a charging period of the battery module.

  • High speed synchronous counter system and process with look-ahead carry generating circuit
    Patent number: 5062126
    Abstract: High speed synchronous counters are constrained to operate within certain speeds due to delays inherent in the counter configurations. By utilizing look-ahead carries, that is, producing carry signals in anticipation of when they might be required, much of the delay can be eliminated. Speed performance can be further improved by fashioning the look-ahead carry system from programmable gate arrays, where non-standard logic structures can be created.
