  • Patent number: 10625569
    Abstract: An engine controller includes a reading section and a ratio-setting control section. The reading section is included in an air conditioner. The air conditioner draws an air into an air-conditioner housing, heats the air by a cooling water cooling the engine, and blows the air into a vehicle compartment. The reading section reads a state information that relates to a state of the air conditioner having an effect on an outside-air drawing ratio. The outside-air drawing ratio is a ratio of a volume of an outside air to a total volume of the outside air and an inside air. The ratio-setting control section decreases an amount of heat generated by the engine when the outside-air drawing ratio is a second ratio, which is smaller than a first ratio, to be smaller than an amount of heat generated by the engine when the outside-air drawing ratio is the first ratio.

  • Patent number: 7454780
    Abstract: This invention relates to a service providing system and a service providing method for allowing users to receive a service from a service server without having to submit their security-critical information to that server. A CE device 1 requests provision of the service by transmitting authentication information such as a device ID to a surrogate authentication server 2. The surrogate authentication server 2 authenticates the CE device 1 based on the authentication information and transmits a result of the authentication to the service server 3. In turn, the service server 3 provides the CE device 1 with the requested service based on the result of the authentication received from the surrogate authentication server 2. The CE device 1 then uses the service provided by the service server 3. This system can be applied advantageously to network-based marketing systems.
