Publication number: 20040113891Abstract: A method for transmitting and receiving data of a wireless keyboard. In the method for transmitting keyboard data between a computer and a wireless keyboard having a plurality of general keys and a number of function keys, the keyboard data is generated in response to a key press or press release. The keyboard data includes fixed data containing a leader indicating a transmission of the keyboard data, variable data, and inverted variable data. The variable data includes a 1-bit special bit indicating whether a function key has been pressed, a make/brake bit indicating whether a key has been pressed, and a scan code corresponding to a pressed or press-released key. After the keyboard data is generated, the generated keyboard data is transmitted through an air interface. A data error can be confirmed without assigning a checksum bit field to the keyboard data. An amount of battery power consumption can be minimized irrespective of a demodulation method.Type: ApplicationFiled: June 23, 2003Publication date: June 17, 2004Inventor: Jee Sung Lee

Patent number: 5861822Abstract: A wire/wireless keyboard and a control method therefor. The keyboard can be used as a wire keyboard if a main body connecting section of the keyboard is connected to a computer body, and the keyboard can be used as a wireless keyboard if the main body connecting section of the keyboard is disconnected from the computer body. The connection status between the computer body and the main body connecting section of the keyboard is automatically judged. If it is judged that they are connected, then the power of the computer body is selected, and the wire mode is executed. On the other hand, if it is judged that they are disconnected from each other, then the internal battery is selected to supply the power from the battery, and the wireless mode is executed. Therefore, the keyboard can be used as both a wire keyboard and as a wireless keyboard.Type: GrantFiled: September 2, 1997Date of Patent: January 19, 1999Assignee: Samsung-Electro Mechanics Co., Ltd.Inventors: Chan Kyung Park, Jee Sung Lee
