May 21, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- HTC Corporation (Taoyuan, TW) has been issued patent number 8719460, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Hung, Ching-Chung (Taoyuan County, TW); Kuan, Tsung-Pao (Taoyuan County, TW); Lai, Yu-Peng (Taoyuan County, TW); Hsu, Chia-Wei (Taoyuan County, TW); Chou, Hsiu-Hung (Taoyuan County, TW).

This patent was filed on February 5, 2010 and was published online on May 6, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "The invention relates to a method for an electronic device for detecting and identifying a peripheral device, and more particularly to a method for an electronic device for automatically detecting and identifying a peripheral device.

"Conventional portable electronic devices, such as cell phones or personal digital assistants, identify different peripheral devices via different corresponding connecting ports. For example, a portable electronic device may connect to earphones and chargers via different connecting ports. Given miniaturization demands, decreasing the amount of connecting ports through integration may decrease area required thereof. However, an efficient method for an electronic device for automatically identifying peripheral devices is required for integrated connecting ports."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "An embodiment of the disclosure provides a method for an electronic device for automatically detecting and identifying a peripheral device. The electronic device comprises a connector having a first pin and a second pin, and connects to a peripheral device. The method comprises the steps of determining whether the peripheral device is connected to the connector; reading a first state of the first pin and the second pin when determining that the peripheral device is connected to the connector; setting a voltage of the first pin to a first voltage level and then reading a second state of the first pin and the second pin; and identifying the peripheral device according to the first state and the second state.

"Another embodiment of the disclosure provides an electronic device capable of automatically detecting and identifying a peripheral device. The electronic device comprises a controller and a connector. The connector comprises a first pin and a second pin coupled to the controller, wherein when the connector is connected to the peripheral device, the controller reads a first state of the first pin and the second pin, and when the controller finishes reading the first state, the controller sets a voltage of the first pin to a first voltage level, reads a second state of the first pin and the second pin, and identifies the peripheral device according to the first state and the second state.

"Another embodiment of the disclosure provides an electronic system. The system comprises a peripheral device and an electronic device. The peripheral device comprises a third pin and a fourth pin. The electronic device comprises a controller and a connector. The connector comprises a first pin and a second pin coupled to the controller, wherein the electronic device is connected to the peripheral device via the connector. When the electronic device is coupled to the peripheral device, the first pin and the second pin are respectively coupled to the third pin and the fourth pin, and the controller reads a first state of the first pin and the second pin. When the controller finishes reading the first state, the controller sets a voltage of the first pin to a first voltage level, reads a second state of the first pin and the second pin, and identifies the peripheral device according to the first state and the second state.

"A detailed description is given in the following embodiments with reference to the accompanying drawings."
