  • Patent number: 8363033
    Abstract: A capacitance sensing circuit for a touch panel includes an analog capacitance-detecting circuit, a PWM-to-digital circuit and a self-calibration circuit. The analog capacitance-detecting circuit detects the capacitance of the touch panel based on a charging current, and converts the detected capacitance into a PWM control signal. The PWM-to-digital circuit converts the PWM control signal into a sensing count value based on a clock signal. The self-calibration circuit adjusts the value of the charging current or the frequency of the clock signal according to the difference between the range of the sensing count value and a predetermined detecting range. The predetermined detecting range can thus be adjusted for matching the range of the sensing count value.

  • Publication number: 20120299612
    Abstract: An elastic micro high frequency probe includes a conductor, which includes a stationary body and a movable body. The stationary body has a conductive terminal, a contacting end, and a guider. The movable body has a conductive terminal, a spring mechanism, and a guider. The spring mechanism is connected to the stationary body and to one conductive terminal. The second guider connects to the spring mechanism in such a manner that the compression direction of the spring mechanism is confined by a guiding rail. Since the width of the spring mechanism is not limited by the first and second guiders, the width of the spring mechanism can be enlarged to maximize within limited space. Therefore, the HF probe as a whole can have shortest length while acquiring the predetermined total length of the elastic stroke, such that the transmission performance of the high frequency signals can be effectively enhanced.

  • Publication number: 20120290117
    Abstract: A method for forming indicia on a semiconductor device package, such as laser marked or ink stamp marked indicia. The method can be performed on an apparatus, such as a production apparatus, which forms the indicia as well as performs semiconductor device trim and form operations. An embodiment of the present teachings ensures that the indicia marking process at a laser marking station does not occur simultaneously with the device trim and form operations at a trim and form station. Trim and form operations, particularly using a ram press, can impose vibrations on the laser marking station. Ensuring that laser marking does not occur simultaneously with trim and form operations removes the negative effects of vibration on the laser marking station.

  • Patent number: 8294048
    Abstract: A sensor structure of a touch panel and a method of determining a touch signal generated by the same are disclosed. The sensor structure includes a plurality of sensor lines disposed on a surface of a substrate, and a control circuit electrically connected to the sensor lines. Each of the sensor lines has a plurality of conductive pads and a conductive line electrically connected the conductive pads. The control circuit receives a touch signal from one of the sensor lines. The touch signal is resulting from a touch capacitance generated between a touch and one of the conductive pads of the sensor line. The control circuit calculates the position of the touch based on the touch capacitance. In addition, the touch capacitance generated by a conductive pad close to the control circuit is larger than the touch capacitance generated by another conductive pad further away from the control circuit.

  • Patent number: 8259087
    Abstract: In a capacitance sensing analog circuit of a touch panel sensing circuit, by raising a magnitude of a current flowing through a sensing capacitor to form an amplified sensing capacitance, while sensing the amplified sensing capacitance with the aid of pulse width modulation signals, higher resolution of the original sensing capacitance may thus be achieved. Besides, by using a self-calibrating capacitance sensing circuit on the touch panel sensing circuit, linear errors and DC errors of an output signal of the capacitance sensing analog circuit may be filtered off, and thereby resolution of a capacitance amplifying ratio may be effectively raised so as to relieve errors within the capacitance amplifying ratio caused by noises.
