  • Exhaust gas heat recovery system
    Patent number: 10245917
    Abstract: A powertrain includes an engine, an exhaust system including an exhaust passageway in fluid communication with the engine, an exhaust gas heat exchanger, a transmission having a transmission cooling system, a transmission heat exchanger, a heater core, a pump, and an engine coolant circuit. The engine coolant circuit provides fluid communication between the engine, the exhaust gas heat exchanger, the transmission heat exchanger, the heater core, and the pump. The exhaust gas heat exchanger is operatively connected to the exhaust system and configured to transfer heat between the engine coolant circuit and the exhaust system. The transmission heat exchanger is operatively connected to the transmission cooling system and configured to transfer heat between the engine coolant circuit and the transmission cooling system.

  • Characterizing slave clock synchronization behavior by means of dropped sync packets
    Patent number: 9560611
    Abstract: Methods, media, and systems are provided for characterizing the synchronization behavior of a slave clock. A sequence of sync packets, usable to synchronize with a grandmaster clock, is transmitted from the grandmaster clock to a slave clock. The sequence of sync packets is modified by dropping one or more sync packets from the sequence, providing a pattern of dropped sync packets. A synchronization output of the slave clock is monitored and, based on the synchronization output, a determination is made as to whether the slave clock is synchronized while the sequence of sync packets is modified. A characterization of the synchronization behavior of the slave clock is stored with respect to the pattern of dropped sync packets. The process may be repeated for various patterns of dropped sync packets.

  • Controlling advertisement of management prefixes
    Patent number: 7710967
    Abstract: A management scheme compares a source address included in a received solicitation with an address for a registered endpoint. A communication including a management prefix is communicated to the endpoint when the source address matches the registered address.
