  • Publication number: 20190121489
    Abstract: A serial communication method between a device and a host, in which the device reports touch data including a coordinate of a detected active stylus to a host. The host issues a write command that includes data indicating a request of a descriptor, to the device. After the device performs a predetermined process for the write command, the device transmits an interrupt to the host. The host requests the device to transmit the touch data, triggered by the host detecting the interrupt. The device transmits the descriptor in response to a request for transmission of the touch data. The method can enable a sensor controller to notify the host of the descriptor even in a case where communication is performed between the sensor controller and a host processor in accordance with a standard that does not provide a command usable for the device to notify the host of the descriptor.

  • Publication number: 20190039433
    Abstract: A vehicular air conditioning device includes a blower, a heating heat exchanger, an auxiliary heater, and a blower controller. The heating heat exchanger heats blown air by exchanging heat between the blown air and the cooling water of the in-vehicle device emitting heat during operation. The blower controller is configured to control the operation of the blower. The blower controller is configured to increase a blowing capacity of the blower with increase of a temperature of the cooling water. The blower controller, during operation of the auxiliary heater, increases the blowing capacity after a waiting time during which the increase of the blowing capacity is prohibited has elapsed since a start-up switch of a vehicle system is turned on. The vehicular air conditioning is capable of implementing a quick warming of the in-vehicle device without impairing the heating feeling of occupant.
