    • A POS terminal apparatus is adapted to be connected to an external device. With an application running in the POS terminal apparatus, a device manager determines whether the external device is capable of counting a first value indicating a usage amount of the external device, and if so, the device manager acquires the first value from the external device in response to a first command from the application. A counter retains a second value indicating the usage amount of the external device and notifies the second value to the application in response to a second command from the application. If it is determined that the external device is not capable of counting the first value, the counter virtually counts the second value in accordance with a third command sent from the application to the external device. An updater updates the second value with a third value which is obtained by a fourth command from the application. The first value is retained even when the second value is updated with the third value.
    • POS终端装置适于连接到外部设备。 通过在POS终端装置中运行的应用程序,设备管理器确定外部设备是否能够计数指示外部设备的使用量的第一值,如果是,则设备管理器从外部设备获取第一值 响应应用程序的第一个命令。 计数器保留指示外部设备的使用量的第二值,并响应于来自应用的第二命令向应用通知第二值。 如果确定外部设备不能计数第一值,则计数器根据从应用程序发送到外部设备的第三命令虚拟地计数第二值。 更新者用第四个命令从应用程序获得的第三个值更新第二个值。 即使第二个值用第三个值更新,第一个值也被保留。

    • A drive circuit of a fan motor is provided. In an embodiment of the drive circuit, a first PWM comparator compares a temperature detection voltage with a cyclic voltage, and outputs a first PWM signal. A second PWM comparator compares a minimum frequency setting voltage indicating a minimum frequency of the fan motor, with the cyclic voltage, and outputs a second PWM signal. The drive circuit combines the first PWM signal and the second PWM signal by a logical operation, to drive the fan motor. The drive circuit includes a first logic gate which generates a logical sum of the first PWM signal and the second PWM signal, and a second logic gate which generates a logical product of the first PWM signal and an inverted signal of the second PWM signal. The drive circuit switches drive mode based on the first logic gate and the second logic gate.
