  • Patent number: 7349009
    Abstract: A phase shifter (70) for correcting the phase of a sub-carrier signal input into a decoder to a burst signal has a phase shift setting (5), a correction amount setting (9?), a phase shifter (6) and a 90-degree phase shifter (7). The phase shift setting (5) holds a phase shift amount for all the scanning lines. The correction amount setting (9?) holds a correction phase shift amount for every part of all the scanning lines. The phase shifter (6) partially shifts the phase of the sub-carrier signal in a unit of part of all the scanning lines, and shifts it in a unit of all the scanning lines, based on said phase shift amount and said correction phase shift amount. The 90-degree phase shifter (7) generates a sub-carrier signal orthogonal to said phase shifted sub-carrier signal.

  • Publication number: 20080053128
    Abstract: In a vehicle air conditioner, when a passenger set temperature of a vehicle compartment is changed through an operation portion by a passenger, a storage portion updates a value of a control set temperature corresponding to a predetermined point of a detection area at a time of the changing operation to a value of the changed passenger set temperature, and stores therein the value of the updated temperature. Furthermore, when the detection point is not any one of the predetermined points, a control portion interpolates and calculates a control set temperature corresponding to the detection point from the control set temperature stored in the predetermined point of the detection area and the control set temperature stored in the predetermined point of a surrounding area around the detection area, and then controls the air-conditioning state in the vehicle compartment based on the interpolated and calculated control set temperature.

  • Patent number: 7028493
    Abstract: In a vehicle air conditioner, a front air conditioning unit and a seat air conditioning unit are automatically controlled by an air conditioner ECU. If a seat air conditioner switch is operated by a user during an automatic control, the setting (e.g. air volume of a seat blower) of the seat air conditioning switch is learned. Based on the learning, a seat blower characteristic diagram, which is stored in a ROM, is changed. Therefore, from this time onward, under the same environmental condition, the seat blower air volume is determined based on the changed seat blower characteristic diagram. Accordingly, a seat air conditioning is provided as desired.

  • Patent number: 6945060
    Abstract: A vehicle air conditioning system is capable of learning preferences for a plurality of passengers, altering control characteristics of air conditioning means based on the results of learning, and automatically controlling the system. The system is capable of adjusting a temperature separately and independently for the left and right sides of a passenger compartment, and stores a temperature setting map of preferences of respective passengers for the Dr side and Pa side. Temperature set points are used for calculating blowing temperatures and determining opening degrees of air mix dampers. If a set point temperature is changed by a manual setting, the temperature-setting map is altered and restored by learning such change, and thus the temperature-setting map can be updated to reflect preferences of each passenger for each of the Dr side and Pa side.
