Patent number: 7848786Abstract: A portable electronic device has various functions such as mobile communication, multimedia entertainment, and data processing. The device includes a main body installed with two keyboards and two slide rails, and two sub-bodies respectively equipped with a display. The sub-bodies are pivoted to each other and rotate through a shaft, and slide along slide rails through connecting members on the main body respectively. Therefore, the sub-bodies can be lifted relative to the main body through the shaft and the connecting members, so as to be optionally drawn close to the main body with the two displays facing the same direction, or to stand on the main body with the two displays facing opposite directions. Therefore, two different operating modes are achieved.Type: GrantFiled: March 7, 2008Date of Patent: December 7, 2010Assignee: Foxconn Communication Technology Corp.Inventors: Chung-Yu Liu, Wang-Hung Yeh, Ping-Chu Tsai

Publication number: 20090160776Abstract: A hand-held electronic device being held by a user with a single hand for dialing or with both hands for inputting characters includes a body, a keyboard, two sensors respectively disposed on two opposite sides of the body, and a backlight source. The keyboard has keys forming a region marked with a QWERTY keyboard and a region overlapping the above region and marked with a phone keypad. The sensors detect whether the body is held by a single hand on one side or by both hands on two sides and let the backlight source light up the region marked with the phone keypad on the keyboard when the body is held by a single hand. Thus, the region marked with the phone keypad is highlighted out of the QWERTY keyboard, so it is easy for the user to identify the key numbers and dial quickly.Type: ApplicationFiled: February 22, 2008Publication date: June 25, 2009Applicant: MOBINNOVA HONG KONG LIMITEDInventors: Ping-Chu Tsai, Hung-Ming Chen, Chung-Yu Liu

Publication number: 20090107828Abstract: A keyboard with five-direction keys is used for a portable electronic apparatus. The keyboard includes a casing with a plurality of openings; and a plurality of keys arranged on the casing in array fashion. Four pattern areas are printed on four diagonal corners of each opening. A legend is printed on each of the pattern areas. The legend is one of letters A to Z, and special symbols such as star key and pound key, and direction signs. Each of the keys is located in one opening, and includes a joystick unit and a keycap arranged on the joystick unit. The keycap comprises a keytop thereon and the keytop is printed with one of numbers 0 to 9. The keyboard generates an electronic signal corresponding to one legend when the keycap is moved laterally in diagonal direction. The keyboard generates an electronic signal corresponding to a number when the keycap is pressed downward.Type: ApplicationFiled: October 29, 2007Publication date: April 30, 2009Inventors: Wang-Hung Yeh, Chung-Yu Liu
