Abstract: The present disclosure is directed to a device that provides high impedance contact pads for an electrostatic charge sensor. The contact pads are shared between the electrostatic charge sensor and drivers. The contact pads are set to a high impedance state by reducing current leakage through the drivers. Compared to electrostatic charge sensor with low impedance contact pads, the electrostatic charge sensor disclosed herein has high sensitivity, and is able to detect weak electrostatic fields.

Abstract: A substrate has a plurality of microdots positioned thereon. Each microdot contains one or more primers for gene amplification for a particular target gene. The microdots are placed on the substrate and the substrate is positioned in a housing. The housing has a sample fluid to be tested introduced therein covering the microdot array. While the sample fluid is overlying the substrate, the amplification of the target gene is carried out if it is present within the sample. If the target gene that matches the primers is not present, then amplification will not take place. The fluid also contains fluorophores which will be fixed into the gene as it increases in size as it clearly detects if gene amplification has occurred by detecting the amount of light detected for a particular microdot. In a preferred embodiment, the sample fluid is placed on top of a sealing layer that is less dense then water, such as wax or mineral oil. During a heating of the sample fluid and sealing layer, the sample fluid will sink to the bottom of the sealing layer so that it is fully encased and protected.

Abstract: A method is provided for controlling an electronic apparatus on the basis of a value of a lid angle between a first hardware element accommodating a first magnetometer and a second hardware element accommodating a second magnetometer. The method includes acquiring, through the magnetometers, first signals representing an orientation of the hardware elements. A calibration parameter indicative of a condition of calibration of the magnetometers is generated on the basis of the first signals. A reliability value indicative of a condition of reliability of the first signals is generated on the basis of the first signals. A first intermediate value of the lid angle is calculated on the basis of the first signals. A current value of the lid angle is calculated on the basis of the calibration parameter, of the reliability value, and of the first intermediate value, and the electronic apparatus is controlled on the basis of the current value.

Abstract: A method of controlling a half-bridge circuit includes receiving an analog feedback signal proportional to an output of the half-bridge circuit, comparing the received analog feedback signal with a threshold value, selecting a digital feedback signal based on a result of the comparing, comparing the digital feedback signal with a digital reference signal to generate a digital error signal, integrating the digital error signal to generate an integration error signal, downscaling the integral error signal to generate a downscaled integration signal, sampling the downscaled integration signal to generate a sampled integration signal, and generating pulsed signals from the sampled integration signal to provide an input to the half-bridge circuit.

Abstract: In accordance with an embodiment, a system includes an oscillator equipped circuit having an oscillator control circuit configured to be coupled to an external oscillator and a processing unit comprising a clock controller. The clock controller includes an interface circuit configured to exchange handshake signals with the oscillator control circuit, a security circuit configured to receive the external oscillator clock signal and configured to select the external oscillator clock signal as the system clock, and a detection block configured to detect a failure in the external oscillator clock signal. Upon detection of the failure, a different clock signal is selected as the system clock and the interface circuit to interrupts a propagation of the external oscillator.

Abstract: A method and apparatus for adaptive rectification for preventing current inversion in motor windings are provided. In the method and apparatus, first and second half bridges of a plurality of half bridges are operated to synchronously rectify and permit passage of current, through the windings of the motor, in a first direction. A change of direction of the current from the first direction to a second direction opposite the first direction is detected. In response to detecting that the current changed direction to the second direction, the first and second half bridges of the plurality of half bridges are operated to quasi-synchronously rectify and block passage of the current through the windings in the second direction.

Abstract: The present disclosure is directed to a MEMS gyroscope formed by a substrate and a movable mass suspended on the substrate and configured to carry out a movement in a driving direction and in a detection direction perpendicular to each other. The movable mass has a first face and a second face opposite to the first face. The gyroscope also has a first and a second quadrature compensation electrode group, fixed to the substrate and capacitively coupled to the movable mass. The first quadrature compensation electrode group faces the first face of the movable mass, and the second quadrature compensation electrode group faces the second face of the movable mass. The first and the second quadrature compensation electrode groups each have a respective variable facing area on the movable mass as a result of the movement of the movable mass in the driving direction and are configured to exert an electrostatic force on the movable mass during the movement of the movable mass in the driving direction.

The floating pockets are shaped and arranged relative to the body wells so that a maximum intensity of electrical field around the floating pockets is greater than a maximum intensity of electrical field around the body wells at least for values of a conduction voltage between the first conduction terminal and the second conduction terminal greater than a threshold voltage, the threshold voltage being less than the maximum nominal voltage.
