Patent number: 9673000Abstract: A multifunction key includes a key member, a conductive member, and a circuit baseboard. A portion of the key member extends out from a shell of an electronic device; the conductive member is fixed on a bottom of the key member. The conductive member includes a first protrusion member and a second protrusion member. One surface of the circuit baseboard includes a conductive layer and a resistance layer respectively contacting the first and the second protrusion member. Another surface of the circuit baseboard includes a first and second conductive terminal respectively connected to the conductive layer and the resistance layer. The conductive layer, resistance layer, first and second conductive terminal, conductive member, and an internal circuit of the electronic device form a circuit loop. When the key member moves, a resistance value of the resistance layer within in the circuit loop is changed and produces a corresponding key command.Type: GrantFiled: June 30, 2015Date of Patent: June 6, 2017Assignees: SHENZHEN FUTAIHONG PRECISION INDUSTRY CO., LTD., FIH (HONG KONG) LIMITEDInventors: Su-Tzong Liu, Sheng-Ying Liu, Wei-Rong Xiao

Patent number: 8523405Abstract: An LED illuminating device comprises a housing with a base plate, a prism sheet and a circuit board. The prism sheet is mounted in the housing and comprises a number of V-shaped micro-grooves formed thereon along three directions intersecting with each other. The circuit board is fixed on the base plate, wherein a plurality of LED units are arranged on the circuit board, each two adjacent LED units are spaced a preset distance apart from each other and emit light of different colors. Six virtual mixed light sources are formed by reflection of the prism sheet to the circuit board when the light emitted by an LED unit mixes with light emitted from adjacent LED units on the circuit board. Each of the virtual mixed light sources has a color different from the colors of the light emitted from the LED units.Type: GrantFiled: April 20, 2011Date of Patent: September 3, 2013Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Shao-Han Chang, Qing-Shan Cao, Su-Tzong Liu
