An assembly for mounting an ultrasound transmitter is provided. The assembly comprises an assembly body having a proximal end, a distal end and perimeters which are perpendicular to a longitudinal axis of the assembly body. The assembly body includes a proximal mount section with a proximal outer perimeter and a proximal inner perimeter which is smaller than the proximal outer perimeter. The assembly body also includes a distal mount section with a distal outer perimeter and a distal inner perimeter which is smaller than the distal outer perimeter. A loop shaped ultrasound transducer abuts the proximal mount section and the distal mount section.

Mount for ultrasound transducer

An ultrasound welding component is disclosed. One embodiment of the component includes a weld region about which an ultrasound weldable material may be wrapped. The weld region includes a weld zone consisting of recesses positioned on opposing sides of a weld area. The recesses and weld area each having widths selected such that an ultrasound source compressing overlapping sections of the ultrasound weldable material against the weld area forms a weld having a width which is narrower than a sum of the widths of the recesses and the weld area. The component also includes a mechanism which immobilizes the ultrasound weldable material relative to the weld zone.

Ultrasound welding apparatus

A system is provided for recording writing performed on a surface. The system includes a stylus having a housing and a writing element; two or more detectors which may be permanently or removably affixed to a writing surface; and a processing unit. The stylus and detectors are used in combination to detect the position of the stylus on the writing surface relative to the detectors based on a time of flight of a ranging medium propagated between the stylus and detectors. The relative position of the stylus is determined at multiple times during which the stylus is being employed in order to record the writing on the surface.
