Abstract: A hearing device seal module having a tubular seal carrier formed from resilient material, defining a medial-lateral axis and a lumen configured for passage of the hearing device core, and including a seal support region with a first portion defining a first portion perimeter in a plane perpendicular to the medial-lateral axis and a second portion, lateral of the first portion, defining a second portion perimeter in a plane perpendicular to the medial-lateral axis that is less than the first portion perimeter when the seal support region is in an unstressed state, and a first seal secured to the first portion of the seal support region and extending outwardly therefrom.

Abstract: A hearing device sizer apparatus including a medial sizer, with a medial core portion and a medial seal secured to the medial core portion, and a lateral sizer, with a lateral core portion and a lateral seal secured to the lateral core portion, that are configured to be releasably engaged with one another.

Abstract: This invention relates to a device for insertion of a deep-in-the-canal hearing aid—alternatively designatable as extended wear hearing aid—into an ear canal of an individual user, at a pre-determined insertion depth (d) thereof. The insertion device comprises a customized support comprising an outer profile conforming to the shapes of at least a portion of a conchal cavity and of an ear canal of said individual user; and a guide channel, disposed internal to said outer profile, extending between a lateral entry opening thereof, for loading said hearing aid; and a medial exit opening thereof, for releasing said hearing aid into said ear canal. The present invention also relates to a method of manufacturing an insertion device for inserting a hearing aid deep into an ear canal of an individual hearing aid user, at a pre-determined insertion depth (d) thereof.

Abstract: Hearing devices, configured to fit within the ear canal, that include a hearing device core, a seal, including a shell wall and a cavity that has an opening located at the end of the shell wall, and a volume of viscous medium located within the cavity between the hearing device core exterior surface and the shell wall interior surface.

Abstract: A system for generating a database of labeled foreign canonical titles includes an interface and a processor. The interface is to receive a title in a second language. The processor is to 1) store a set of n-grams in a first language in a first database; 2) sanitize the title into a sanitize title in the second language; 3) translate the sanitized title into a translated title in the first language; 4) break the translated title into n-grams; 5) determine labels for the n-grams using the first database; and 6) determine label to associate with the title.

Abstract: A fiber coupled semiconductor device having an improved optical stability with respect to temperature variation is disclosed. The stability improvement is achieved by placing the platform holding the semiconductor chip and the optical fiber onto a spacer mounted on a base. The spacer has an area smaller than the area of the platform, for mechanical decoupling of thermally induced deformation of the base from a deformation of the platform of the semiconductor device. Attaching the optical fiber to a vertical mounting surface of a fiber mount, and additionally attaching the fiber mount to a submount of the semiconductor chip further improves thermal stability of the packaged device.

Abstract: An apparatus for producing a vacuum arc plasma source device using a low mass, compact inductive energy storage circuit powered by a low voltage DC supply acts as a vacuum arc plasma thruster. An inductor is charged through a switch, subsequently the switch is opened and a voltage spike of Ldi/dt is produced initiating plasma across a resistive path separating anode and cathode. The plasma is subsequently maintained by energy stored in the inductor. Plasma is produced from cathode material, which allows for any electrically conductive material to be used. A planar structure, a tubular structure, and a coaxial structure allow for consumption of cathode material feed and thereby long lifetime of the thruster for long durations of time.
