  • Patent number: 10523234
    Abstract: A signal processing arrangement has a signal input for connecting a capacitive sensor. An amplifier circuit is coupled between the signal input and a feedback point. A loop filter is coupled downstream to the feedback point. A quantizer is connected downstream to the loop filter and provides a multi-bit output word. The multi-bit output word consists of one or more higher significance bits and one or more lower significance bits. A first feedback path is coupled between a quantizer and the feedback point for providing a first feedback signal to the feedback point being representative of the one or more lower significance bits. A second feedback path is coupled to the quantizer for providing a second feedback signal to the signal input being representative of the one or more higher significance bits.

  • Publication number: 20190356282
    Abstract: A MEMS sensor (1) comprises a MEMS transducer (10) being coupled to a MEMS interface circuit (20). The MEMS interface circuit (20) comprises a bias voltage generator (100), a differential amplifier (200), a capacitor (300) and a feedback control circuit (400). The bias voltage generator (100) generates a bias voltage (Vbias) for operating the MEMS transducer. The variable capacitor (300) is connected to one of the input nodes (I200a) of the differential amplifier (200). At least one of the output nodes (A200a, A200b) of the differential amplifier is coupled to a base terminal (T110) of an output filter (110) of the bias voltage generator (100). Any disturbing signal from the bias voltage generator (100) is a common-mode signal that is divided equally on the input nodes (I200a, I200b) of the differential amplifier (200) and is therefore rejected.

  • Publication number: 20150066524
    Abstract: Methods and systems to facilitate the collaborative development, discovery and implementation of evidence-based, clinical pathways are disclosed. Clinicians, medical professionals or researchers, may use the Platform 105 in multiple implementation, such as integrated with a third-party system like an EHR 104 to build and find clinical pathways through a graphical interface, creating relational data records between steps in pathways. Further, users of the Platform 105 may be able to associate relevant content such as published evidence, supplemental content items (e.g., videos, images, documents, ICD, CPT, SNOMED codes, and external web pages), and other associated pathways which reside in the system's database. Users of the Platform 105 may be able organize themselves into groups and networks to develop single pathways collaboratively. Users may be able to find specific pathways in the Platform 105 through semantic search, querying for relationships which exist inside of individual pathways.

  • Patent number: 8188731
    Abstract: A controller includes a control circuit. The control circuit includes a forward path that includes an input and an output, a feedback path coupled to the output and to the input, and a sensor that is between the input and the output. The sensor generates a sensor signal based on an input signal applied to the input. The forward path generates an output signal based on the sensor signal. The output signal is sent along the feedback path to the input of the forward path. The controller also includes a detector that obtains an intermediate signal from the forward path between the input and the output. The detector generates a control signal using the intermediate signal. The forward path includes a control device that limits the output signal to a predetermined value. The detector controls the control device using the control signal.

  • Patent number: 7884557
    Abstract: A light source is protected by selectively coupling a shunt path in parallel with the light source, such that current is diverted away from the light source and through the shunt path. A detection circuit detects the current flowing in the shunt path when the shunt path is connected in parallel with the light source. A comparator determines whether the current flowing in the shunt path exceeds a predetermined threshold and, if so, prevents or limits the flow of current when the shunt path is disconnected from being in parallel with the light source. In this way, a current detector is provided for monitoring the flow of current in a shunt path, the current detector being configured to disable or limit the flow of current through a light source when a predetermined threshold is reached.

  • Patent number: 7884558
    Abstract: A driver apparatus is provided for controlling a light source array comprising at least first and second light sources, the light source array used for illuminating a scan region on a target object, wherein light reflected from said target object is captured by a detector. The driver apparatus comprises a single integrated circuit comprising processing means for processing image data received from the detector, a switching array comprising at least first and second switches for switching the respective first and second light sources, and a current source for controlling the flow of current through the light sources. In this way the LED switching circuitry that controls an LED array is 15 placed on the same integrated circuit (i.e. monolithic circuit) as the analogue processing circuitry that processes the image data, with the current source controlling the flow of current through the LEDs in the LED array.

  • Patent number: 7701207
    Abstract: A sensor, in particular a Hall sensor, comprising a sensor element (1; 10) which outputs a sensor signal (SS) containing an interference signal (STS). An evaluation device (6; 20) is connected to the sensor element and contains a subtractor (2; 21) which subtracts the interference signal from the sensor signal. The sensor contains a filter device (3), which filters out the interference signal from the sensor signal. The sensor and a related method enable compensation of the interference signal.

Plural signal modulators receive sense signals that correspond to sensor signals from corresponding ones of the plural sensors. Each of the plural signal modulators has first and second control states. In the first control state, each signal modulator outputs sense signals, and, in the second control state, each signal modulator outputs inverted sense signals. A device receives and processes the sense signals or the inverted sense signals.
