摘要： An electromechanical system (MEMS) voltmeter. An exemplary MEMS voltmeter includes a proof mass mounted to a substrate in a teeter-totter manner. The MEMS voltmeter also includes an input voltage plate located on the substrate under a first end of the proof mass. The first input voltage plate receives a voltage from a device under test. A drive voltage plate is located on the substrate under a second end of the proof mass. A first sense input voltage plate is located on the substrate under the first end of the proof mass. A second sense voltage plate is located on the substrate under the second end of the proof mass. A rebalancing circuit receives signals from the proof mass and the first and second sense voltage plates and generates a voltage value that is equal to the root mean square (RMS) voltage of the device under test.

摘要： A device includes a first oscillator, a second oscillator and a frequency comparison block. The first oscillator includes a first LC tank circuit and is designed to generate first sustained oscillations at a first resonant frequency. The second oscillator includes a second LC tank circuit and is designed to generate second sustained oscillations at a second resonant frequency. The frequency comparison block is designed to perform a comparison of the frequencies of the second sustained oscillations and the first sustained oscillations to determine a change in inductance in one of a first inductor of the first LC tank circuit and a second inductor of the second LC tank circuit. One of the oscillators serves as a reference oscillator, and enables determination of the change in inductance to be immune to changes in environmental conditions.

摘要： Apparatuses and methods of capacitive buttons and detecting and differentiating touches from different size conductive objects on the capacitive buttons. One apparatus includes a capacitance-sensing circuit coupled to a capacitive button. The capacitive button includes a first sense element and a second sense element. The capacitance-sensing circuit is operative to measure signals from the first sense element and the second sense element with a sensing parameter (also referred to as tuning properties) set to a first value. The signals correspond to capacitances of the first sense element and second sense element. An inner perimeter of the first sense element is disposed to surround (at least in part) an outer perimeter of the second sense element. The apparatus further includes processing logic coupled to the capacitance-sensing circuit. The processing logic is operative to detect whether the first sense element is activated by a conductive object proximate to the capacitive button based on the measured signals. The processing logic detects whether the second sense element is activated by the conductive object proximate to the capacitive button based on the measured signals. The processing logic adjusts the first value to a second value for the sensing parameter when the second sense element is activated and the first sense element is not activated. The capacitance-sensing circuit is operative to measure an additional signal from the second sense element with the sensing parameter set to the second value when the second sense element is activated and the first sense element is not activated.

摘要： The analog display device comprises at least one needle driven through a gear wheel by a stepping motor, a control circuit for the motor, bidirectional counter locked with the position of the needle on a dial, the logic states of the outputs of the counter being representative of the position of the needle on the dial and a comparator for the informations delivered by the counter and the informations corresponding to the value of the function to display, the comparator acting at least indirectly on the control circuit and on the counter so that the position of the needle is representative of the value of the function to display. The device does not require any digital-analog converter nor galvanometer and it allows for, example, to display simultaneously with at least two needles the value of at least two different functions, to make changes of scale, and so on. The device may also be combined with another type of analog or digital display.

摘要： Apparatuses and methods of distinguishing between a finger and stylus proximate to a touch surface are described. One apparatus includes a first circuit to obtain capacitance measurements of sense elements when a conductive object is proximate to a touch surface. The apparatus also includes a second circuit coupled to the first circuit. The second circuit is operable to detect whether the conductive object activates the first sense element, second sense element, or both, in view of the capacitance measurements. To distinguish between a stylus and a finger as the conductive object, the second circuit determines the conductive object as being the stylus when the second sense element is activated and the first sense element is not activated and determines the conductive object as being the finger when the first sense element and the second sense element are activated.
