Patent number: 9276428Abstract: According to one embodiment, a management circuit for a portable device includes an input terminal, a first step-up converter, a first step-down converter, and a second step-down converter. The input terminal is coupled to receive a supply voltage from a power supply. The first step-up converter, coupled to the input terminal, selectively converts the supply voltage to a boosted voltage. The first step-down converter, coupled to the first step-up converter, selectively provides a first output power voltage to a first radio frequency (RF) module. The second step-down converter, coupled to the first step-up converter, selectively provides a second output power voltage to a second radio frequency (RF) module. The first step-up converter performs the conversion of the supply voltage when the supply voltage is under a threshold voltage.Type: GrantFiled: December 20, 2011Date of Patent: March 1, 2016Assignee: HTC CORPORATIONInventors: Hsun-Hsin Chuang, Chien-Shen Tsai, Yueh-Hsiang Chen

Patent number: 8417977Abstract: An operating method for an integrated interface of a PDA and a wireless communication system includes the following steps. Firstly, when the wireless communication system starts to operate from a standby mode, a state signal is transmitted from the wireless communication system to the PDA. Then, if the PDA receives the state signal when the PDA is in a sleep state, the PDA is wakened and an input source of an audio element inside the PDA is switched to the wireless communication system. An electromagnetic wave signal is received by a wireless communication element and converted into audio data. Afterwards, the audio data is transmitted from the wireless communication system to the PDA and outputted by the audio element.Type: GrantFiled: May 27, 2010Date of Patent: April 9, 2013Assignee: HTC CorporationInventors: Hsun-Hsin Chuang, Hsi-Cheng Yeh, Chih-Chao Hsieh, Shi-Je Lin, Wen-Hsing Lin

Publication number: 20030189552Abstract: A touch panel threshold pressure setup method and apparatus. In this touch panel threshold pressure setup method, at first multiple touches are performed when the setup is run, and with this, the multiple pressure values can be obtained. Then, the obtained pressure values are averaged to obtain an average pressure value. Finally, the average pressure value itself or a value obtained from a certain multiplier multiplied by the obtained average pressure value is used as a threshold pressure value. Moreover, the pressure value mentioned above can be represented by the contact resistance value if the resistance type touch panel is used. However, the pressure value is inverse proportional to the contact resistance value that represents it.Type: ApplicationFiled: April 1, 2003Publication date: October 9, 2003Inventors: HSUN-HSIN CHUANG, CHIH-CHAO HSIEH, BOSHIUN CHEN
