  • Patent number: 10436102
    Abstract: A cooling system for vehicles and a control method thereof improves indoor heating performance and fuel efficiency by controlling a flow rate of a coolant passing through a heater core together with an EGR cooler. A coolant having an increased temperature is first supplied to the heater core side through a flow stagnancy control to rapidly increase the temperature of the coolant flowing in the heater core, thereby improving heating performance. A warm-up feature is improved through an exhaust heat recovery function by a heat exchange between the exhaust gas and the coolant in the EGR cooler, thereby improving efficiency of fuel.

  • Patent number: 9905922
    Abstract: Techniques for improving coverage of an antenna system are disclosed. In an aspect, a wireless device includes a 3-D antenna system to improve coverage and enhance performance. The 3-D antenna system includes antenna elements formed on multiple planes pointing in different spatial directions. Antenna elements formed on the multiple planes are associated with different antenna beams, which can provide a larger line-of-sight (LOS) coverage for the wireless device. Beamforming may be performed for the antennas on a given plane to further improve LOS coverage. Non-LOS (NLOS) coverage may also improve since antenna beams pointing in different spatial directions may result in reflected signals of higher power levels due to better signal reflection for some antenna beams.
