Abstract: A pressure sensor device includes a semiconductor die of the pressure sensor device and a bond wire of the pressure sensor device. A maximal vertical distance between a part of the bond wire and the semiconductor die is larger than a minimal vertical distance between the semiconductor die and a surface of a gel covering the semiconductor die.

Abstract: An ultrasonic touch sensor includes a touch structure configured to receive a touch; a transmitter arrangement configured to transmit one or more ultrasonic transmit waves toward the touch structure; a receiver arrangement configured to receive ultrasonic reflected waves produced by reflections of the one or more ultrasonic transmit waves and generate a plurality of measurement signals representative of the ultrasonic reflected waves; and a measurement circuit configured to measure a degree of variation of a plurality of measurement signals, compare the degree of variation with a detection threshold, and determine whether a no-touch event or a touch event has occurred at the touch structure based on whether the degree of variation satisfies the detection threshold.

Abstract: An ultrasonic transducer includes an arrangement of ultrasonic transducer elements, wherein the ultrasonic transducer elements include a first ultrasonic transducer element and a second ultrasonic transducer element. The first ultrasonic transducer element has a first membrane having a first membrane reinforcement and a first membrane electrode, and a first counter-electrode. The second ultrasonic transducer element has a second membrane having a second membrane reinforcement and a second membrane electrode, and a second counter-electrode. Additionally, a resonant frequency of the first membrane differs from a resonant frequency of the second membrane.

Abstract: Examples provide for an apparatus, method, and computer program for comparing the output of sensor cells in an arrangement of sensor cells in an area A, including a set of at least two measurement units. A measurement unit includes at least two sensor cells, wherein at least one sensor cell of at least one measurement unit includes a sensitive sensor cell, which is sensitive with respect to a measured quantity. The sensor cells are intermixed with each other. The apparatus further includes means for selecting output signals of sensor cells of the arrangement and means for determining a measured quantity or determining an intact sensor cell by comparing output signals of different measurement units.
