Abstract: The application relates to an ultrasonic transducer comprising a carrier with conductor traces and a piezoelectric element with electrodes, wherein the piezoelectric element has a contact side which is fixed on the carrier, and wherein the conductor traces and the electrodes are electrically coupled via the contact side of the element.

Abstract: An acoustic earpiece system includes an earpiece housing having a first bore and a second bore, with the first and second bores being defined to join into a common ear canal bore. An adapter connectable to acoustic tubing is also formed, with the adapter being connected to the earpiece housing and the first bore. In some embodiments a passive or active acoustic filter is positionable in the second bore.

Abstract: Embodiments that relate to detecting via an image sensor inputs made by a group of users are provided. For example, one disclosed embodiment provides a method including receiving image information of the play space from a capture device, identifying a body of a user within the play space from the received image information, and identifying a head within the play space from the received image information. The method further includes associating the head with the body of the user, identifying an extremity, and if the extremity meets a predetermined condition relative to one or more of the head and body, then performing an action via the computing device.

Abstract: The invention is related to a device for the noise suppression of small electric motors with a Cx capacitor to be installed between two connections (A1, A2) of the small electric motor as well as Cy capacitors installed between each of the connections (A1, A2) and a ground of the small electric motor, wherein the Cx capacitor and the Cy capacitors are combined in a disk-shaped component (1) which can be mounted on a housing cover (13) for the small electric motor or is integrated in the housing cover (13).

Abstract: A commutator arrangement for a small electric motor with a capacitor ring disk having several capacitor elements, wherein the capacitor ring disk is made of a dielectric first ring disk (RS) on whose upper side several sector-shaped electrode layers (6) are placed. Each of the electrode layers (6) are electrically conductively connected with a commutator segment (13). Counter electrodes of the capacitor elements are provided on an under side opposite the upper side. To improve the interference suppression features a single counter electrode layer (4), which underlies almost the entire surface of the electrode layer (6), is provided on the under side so that the counter electrodes of all capacitor elements have the same potential.
