Abstract: Systems and methods are provided for extracting an implanted lead from a patient's body. The system may include a dilator and a trephine for extracting the electrode lead. A sheath may be included that is advanced over the proximal end of an electrode lead until the distal end of the sheath abuts a collar of the electrode lead coupled to proximal fixation elements. The dilator may be rotatably and axially advanced over the sheath until the distal end of the dilator collapses the proximal fixation elements within a lumen of the dilator. The trephine may then be rotatably and axially advanced over the dilator such that a cutting edge of the trephine cuts tissue surrounding distal fixation elements of the electrode lead to thereby dislodge the electrode lead.

Abstract: A method for measuring a semifinished prism in which a first test beam path is produced, by which a first test image is imaged to infinity, and in which the first test beam path is guided as an incident beam path onto a first non-polished surface of the prism. A beam path reflected from the first non-polished surface is captured by a telescope, wherein the first test image is imaged onto a detector in the telescope. The incident beam path forms an obtuse angle with the reflected beam path. A second test beam path reflected from a second surface of the prism is captured by a telescope, wherein a second test image, which is imaged to infinity by the second test beam path, is imaged onto a detector by the telescope. The angle between the first surface and the second surface is determined on the basis of the difference between an orientation of the first surface, derived from the first test image, and an orientation of the second surface, derived from the second test image.

Abstract: The invention relates to a device for measuring sheets comprising a light source and a light sensor, which are arranged such that a light beam emerging from the light source passes through the sheet and impinges on the light sensor. According to the invention, the light sensor has a dynamic range of more than 8 bits with linear resolution, or has a non-linear resolution. The invention also relates to a corresponding method. The invention makes it possible to reliably measure both a primary beam and a secondary beam of the light beam that passed through the sheet.

Abstract: A therapy cast can provide fixation, compression, or thermal therapy to a patient. The therapy cast can include a support structure configured to couple to a lower leg of a person and configured to at least partially restrict movement of the lower leg. A compression member can be configured to exert a compressive force to a first portion of the lower leg. The compressive force can include a gradient relative to a spatial position of the lower leg. A thermal member can provide thermal therapy to a second portion of the lower leg.

Abstract: This process allows one to create bar code and dot code labels that are sensitive to infrared, visible, and ultraviolet light with out the use of ink. This is accomplished by cutting out or otherwise removing select areas of media to create shapes identical to the outlines of data elements that would be created by infrared, ultraviolet, and visible ink printing systems. This includes but is not limited to the shape of bars in bar coding, the dots in dot coding, lettering, numbering, and images. The method of cutting out the shapes could be manual or with special automated tools, equipment, and machinery. This process offers distinct advantages that qualify it as an improvement over ink printing. It can be done more cheaply, has a stability that is more dependant on the media than the ink, can not wash off, and there are no problems involving insufficient ink and poor print quality.

Abstract: A multi-functional cart for transporting objects including a frame, a first handle connected to the frame adjacent a first end of the frame, a second handle connected to the frame adjacent a second end of the frame, a first pair of wheels connected to the frame adjacent the first end of the frame and a second pair of wheels connected to the frame adjacent the second end of the frame. The handles are different sizes and are selectively movable between perpendicular to the frame and coplanar to the frame. The frame has a generally rectangular configuration and includes frame members which are telescopically connected to each other. The multi-functional cart transforms into eight or more configurations.

Abstract: A system and method for audio coding an audio signal are provided. In one embodiment of the invention, selected masked tones that are reduced in audibility by masking tones are discarded, and those masked tones that are reduced in audibility by a masking tone that when reproduced along with the masking tone result in a perceived difference tone are retained.

Abstract: A convertible cart for transporting objects including a frame, a first handle connected to the frame adjacent a first end of the frame, a second handle connected to the frame adjacent a second end of the frame, a first plurality of wheels connected to the frame adjacent the first end of the frame and a second plurality of wheels connected to the frame adjacent the second end of the frame. The first plurality of wheels are rotatably mounted to a tubular axle. The first plurality of wheels are casters rotatably interconnected to the frame. The handles are selectively movable between a first position perpendicular to the frame and a second position generally coplanar to the frame. The frame has a generally rectangular configuration and includes frame members which are telescopically connected to each other.

Abstract: A convertible cart for transporting objects having a frame, a first handle connected to the frame, a second handle connected adjacent an opposite end of the frame, a plurality of wheels attached to the frame. Each of the handles is selectively movable between a first position generally perpendicular to the frame and a second position generally aligned with the frame. The wheels support the frame at a position parallel to the surface on which the wheels are placed. The frame has a longitudinal member extending centrally of the frame. The longitudinal member has an end offset from overlapping relationship with one end of the frame. A snap button is provided within the longitudinal member so as to limit telescoping movement of one portion of the longitudinal member with respect to another portion.

Abstract: A convertible cart for transporting objects having a frame, a first handle connected to the frame, a second handle connected adjacent an opposite end of the frame, a pair of primary wheels attached to the frame, and at least one secondary wheel attached to an opposite end of the frame. Each of the handles is selectively movable between a first position generally perpendicular to the frame and a second position generally aligned with the frame. The primary wheels and secondary wheel support the frame at a position parallel to the surface on which the wheels are placed. A locking mechanism is provided for the handles which includes a first and second axle members extending inwardly on opposite sides of the frame, a first stop member fastened to the frame so as to abut a surface of the handle, and a cord extending across the handle so as to cause the handle to move along a slide surface of the axle members.
