  • Publication number: 20070164756
    Abstract: Capacitance measurement apparatus that enhances the sensitivity and accuracy of capacitive transducers, proximity sensors, and touchless switches. Each of two capacitors (C1, C2) under measurement has one end connected to ground and is kept at substantially the same voltage potential by operational amplifier (A1) or amplifiers (A0, A1) using negative feedback. The apparatus is driven by a periodic e.g. sinusoidal signal source (G1) or sources (G1, G2) and includes a difference amplifier (A2) operative to produce an electrical signal having a linear relationship with a specified arithmetic function of the capacitances of the two capacitors (C1, C2). A touchless switch is implemented using the capacitance measurement apparatus. The touchless switch includes two sensor electrodes (E1, E2) that correspond to the two capacitors (C1, C2) under measurement and in one embodiment has a front surface in the form of a container.

  • Publication number: 20060290550
    Abstract: A multi-channel digital-to-analog (D/A) conversion system that can produce an analog output (210) from a digital signal (201) using N D/A converters (C1-CN), each with 1/N of the resolution of a single D/A converter used to perform the same D/A conversion. A data sample (Din) of the digital signal (201) is decomposed into N data sub-samples (D1-DN). The sum of the values of the data sub-samples (D1-DN) is equal to the value of the data sample (Din), while the normalized range of the value of the data sample Din is greater than the normalized range of the value of each data sub-sample (D1-DN). Each D/A converter (C1-CN) receives a respective one of the data sub-samples (D1-DN), and generates a respective one of a plurality of analog component outputs (A1-AN) singly or jointly with at least one of the other D/A converters (C1-CN). The analog output (210) is produced by additively combining the plurality of analog component outputs (A1-AN).

  • Publication number: 20050231410
    Abstract: A digital system employing a multi-channel and multi-level PWM technique that allows for smoother transitions in the outputs of the multiple channels in response to variations in the level of a digital input signal. The system generates PWM and other digital control signals to control switching circuitry included in the multiple channels, in which the PWM control signals are generated from a number of LSBs of the digital input signal, and the other digital control signals are generated from the remaining MSBs of the digital input signal. The system provides selected ones of the PWM and other digital control signals to each channel for controlling the switching circuitry included therein. By providing both the PWM and the other digital control signals to the multiple channels in an interleaved manner, smoother transitions in the outputs of the various channels can be achieved, thereby reducing the occurrence of unwanted transients in the system output.
