Patent number: 6166538Abstract: An electronic autoclave cycle passively records the number of thermal cycles to which an instrument has been subjected in a steam autoclave. When a sterilization cycle has been completed, and the instrument is next energized in use, a microprocessor is employed to read the sensor and record the occurrence of a sterilization cycle. Information as to the cumulative number of cycles through which the instrument has been subjected is stored in a non-volatile memory. This data is suitably displayed on a display panel. The sensor employed uses either the Curie temperature or a temperature near but below the Curie temperature of a ferromagnetic material by first magnetizing the material and then, later, checking its flux density to determine whether a thermal cycle has occurred. In a first embodiment, a Hall effect sensor is used to directly measure the magnetic field strength of the magnetizable material.Type: GrantFiled: August 26, 1998Date of Patent: December 26, 2000Assignee: Linvatec CorporationInventor: David A.

Patent number: 5841491Abstract: A system for transmitting an image through the fiber bundle of an optical fiber endoscope is provided, characterized by an electronic filter for substantial removal of distortion such as that introduced by passage of the image through the bundle. The filter is configured with a variable characteristic such as cutoff frequency which can be matched to a predetermined parameter of the bundle such as the density of individual fibers. Thus, the filter can be easily modified to provide optimal performance if the fiber bundle is replaced or modified.Type: GrantFiled: July 23, 1996Date of Patent: November 24, 1998Assignee: Envision Medical Corp.Inventors: David A.
