Abstract: The invention relates to a method for controlling a hearing aid (1a, 1b) using a control unit (7), which is linked to the hearing aid (1a, 1b). The latter receives acoustic signals via a microphone (2a, 2b), amplifies said signals and outputs them by means of a loudspeaker (3a, 3b). In said hearing aid (1a, 1b) digital signals are processed according to a predetermined algorithm and data concerning the acoustic environment is created and forwarded to a control unit (7) via a communication interface (6a, 6b). To improve the quality and ease of operation, the data in the control unit (7) is analysed and an optimal algorithm is calculated, which is transmitted to the hearing aid (1a, 1b) via the communication interface (9).

Abstract: In a spray gun for spraying paint and similar media, there is provided a gun housing and a reservoir tank removably attached to the gun housing for holding the medium to be sprayed. The reservoir tank is configured as a commercially available storage container, for example in the form of a paint can, and is directly attached via an adapter to a projection connected to the gun housing. Thus, commercially available storage containers, differing considerably in their dimensions, can be directly fitted onto the gun housing in a short time and by a reliable method. Viscosity settings and transferring of media to be processed from one container to another are therefore not necessary, and the medium can be matched to the particular working implement and application.

Abstract: A method for determining the degree of twist to be manually introduced into an implant which is to be positioned in the aorta and adjacent iliac branches so as to achieve an effective degree of twist when the implant is positioned in the anatomy, the method comprising: identifying the effective degree of twist desired for the implant; determining the Native Iliac Rotation of a patient; and subtracting the Native Iliac Rotation of a patient from the effective degree of twist desired for the implant so as to determine the degree of twist to be manually introduced into the implant.

Abstract: The present invention relates to inhibiting or preventing infection and protecting against patency complications after a blood catheter has been inserted in a patient comprising administering to the device a pharmaceutically effective amount of a composition comprising: (A) at least one taurinamide derivative, (B) at least one compound selected from the group consisting of biologically acceptable acids and biologically acceptable salts thereof; and (C) heparin at a low concentration.

Abstract: Apparatus for applying thermoplastic strips to thermoplastic membranes, each strip having an upstanding central portion and opposed flange portions extending widthwise therefrom. The apparatus includes a housing having drive wheels for movably supporting the housing. A guide assembly fixed to the housing includes a first pair of guide wheels for disposition around an applied first strip and movable along the first strip with one guide wheel on either side thereof, and a second pair of guide wheels for disposition around a second strip to be applied and movable along the second strip, so as to guide the second strip to a welding station on the apparatus. The welding station is adapted to heat weld the second strip to the membranes along the length of the second strip equidistantly from the first strip.

Abstract: An apparatus and method for detecting physiological function, for example, nerve conduction, is described. In one embodiment the apparatus includes a housing including a stimulator shaped to fit a first anatomical site and a detector shaped to fit a second anatomical site. The housing automatically positions the detector substantially adjacent to the second anatomical site when the stimulator is positioned substantially adjacent to the first anatomical site. The detector contains a plurality of individual detection elements, whereby the response evoked by stimulation at the first anatomical site is measured using one or more of these detection elements at the second anatomical location.
