摘要： A host-to-host chip includes: first and second ports coupled to first and second hosts respectively; and a host-to-host control circuit coupled to the first port and the second port. When the host-to-host chip is coupled to the second host, the host-to-host control circuit identifies whether the second host is an i-Phone or an Android smartphone. If the host-to-host control circuit identifies that the second host is an i-Phone smartphone, in response to a command from the host-to-host control circuit, the second host switches to host role from device role, and the host-to-host control circuit controls whether data is transmitted between the first host and the second host via a DMA path. If the host-to-host control circuit identifies that the second host is an Android smartphone, the host-to-host control circuit determines that data is transmitted between the first host and the second host in a pass-through mode.

摘要： Disclosures of the present invention describe a switch device has a controlling and processing unit comprising a first zero point detector, a second zero point detector, an arc detector, and a microcontroller. According to zero crossing point of input voltage signal, zero crossing point of output voltage signal, relay's delay time, and arc-spark-induced signal, the microcontroller is capable of adaptively generating a relay controlling signal to control the relay, such that the relay achieves a short-circuit switching at the zero cross point of output voltage signal for making the output voltage signal be transmitted to at least one load device. Moreover, the microcontroller is also able to control the relay to finish a short-circuit switching at the zero cross point of input voltage signal, so as to stop the output voltage signal from being transmitted to the load device.

摘要： The present invention provides a method for automatically identifying host operating system. By applying the method of automatically identifying host operating system in a USB control unit of a USB device by a form of application program, library, variables, and/or operands, the USB control unit is therefore provided with a host operating system identifying function. As such, in case of a specific OS of a host device applying a USB enumeration to the forgoing USB device, the central processing unit would automatically identify (or detect) what the specific OS is. For example, the specific OS is identified as an Apple iOS operating system, a Microsoft Windows operating system, an Apple Mac OS operating system, or a Google Android operating system.

摘要： A sensor for sensing a usage status of an electrical device and its associated method are disclosed. The sensor is disposed at a near-end of a power line of the electrical device. The sensor provided with a magnetic detector, an analog-to-digital converter and a controller. The magnetic detector is close to the power line to detect a magnetic field change around the power line to correspondingly generate an analog signal. The analog-to-digital converter (ADC) is used to receive the analog signal and convert the analog signal to a digital signal. The controller is used to receive the digital signal and generate an indication signal to accordingly learn at least one of statuses of being turned on and turned off the electrical device.
