  • Patent number: 11106313
    Abstract: A capacitive sensor system for touch detection includes a sensor surface, a first sensor electrode, a second sensor electrode, and an evaluation device. The sensor electrodes are both situated on and border the sensor surface. The first sensor electrode has a first closed conductor loop and the second sensor electrode has a second closed conductor loop. The first closed conductor loop surrounds the second closed conductor loop without the closed conductor loops touching each other. Each sensor electrode generates a sensor signal that depends on a position of a touch of an object on the sensor surface relative to the closed conductor loop of the sensor electrode. The evaluation device detects the touch based on a comparison of a ratio value to a threshold value, wherein the ratio value is a ratio of (i) a difference and (ii) a sum of the sensor signals.

  • Publication number: 20140076058
    Abstract: A pressure measurement system for use in blood circuits comprised of a pressure sensing pod and a force measurement device. The pressure sensing pod can include a flexible, moveable, fluid-impermeable diaphragm and can be formed via either a one-shot or a two-shot molding process. A mechanical engagement member of the force measurement device engages with a mechanical engagement feature of the diaphragm, and the engagement member is operative to move in concert with movement of the engagement feature of the diaphragm based on pressure variations with the pressure sensing pod. The force measurement device generates and outputs to a processor a signal based on detected force associated with movement of the engagement member.

  • Patent number: 8671766
    Abstract: Some embodiments of the present disclosure relate to improved package assemblies for pressure sensing elements. Rather than leaving a pressure sensing element unabashedly exposed to the ambient environment in a manner that makes it susceptible to damage from stray wires, dirt, and the like; the improved package assemblies disclosed herein include a cover that helps form an enclosure around the pressure sensing element. The cover includes a fluid-flow channel with a blocking member arranged therein. The fluid-flow channel puts the pressure sensing element in fluid communication with the external environment so pressure measurements can be taken, while the blocking member helps protect the pressure sensing element from the external environment (e.g., stray wires and dirt to some extent). In this way, the package assemblies disclosed herein help promote more accurate and reliable pressure measurements than previous implementations.

  • Patent number: 8584527
    Abstract: A single wire interface for a transducer transmits the transducer output as a frequency modulated signal over one single wire during one interval. During a second interval a reference signal is transmitted as a frequency modulated signal. Both the transducer output and the reference signal output are processed by the same circuitry during the respective intervals to provide both frequency modulated signals. The frequencies of the two signals are measured and then the ratio of the two periods which is the reciprocal of the two frequencies is calculated. This ratio is the direct measure of the output of the transducer and when provided eliminates sources of errors.
