  • Medical fluid injector having face plate with magnetic conductors
    Patent number: 6159183
    Abstract: A medical fluid injector includes: an air detection system for detecting air in the neck of the syringe; a hand-operated control lever for controlling movement of the injector ram; magnetic conductors for delivering magnetic fields from a power head face plate to an internal circuit board to permit detection of different face plates; a tilt sensor detecting the tilt angle of the power head to control the speed of motion brought about by the hand-operated control lever and to control an invertible display; and a monitor microcontroller for monitoring the behavior of the central processing unit to detect and react to error conditions.
    Type: Grant
    Filed: November 10, 1999
    Date of Patent: December 12, 2000

  • Laser apparatus including crystal protection circuitry and method of operation thereof
    Patent number: 5177756
    Abstract: A laser apparatus is disclosed which is capable of protecting the laser slab or rod crystal within the laser from damage due to overheating when the laser malfunctions in a manner such that laser output ceases while optical pumping of the laser crystal continues. The laser apparatus includes a laser crystal situated within a laser cavity. The apparatus also includes an excitation lamp for pumping the crystal to generate a laser beam to project along a desired main path. A first sensor senses the cessation of the projection of the laser beam along the desired main path and a second sensor senses the continuing excitation of the excitation lamp. The apparatus further includes a extinguishing circuit for extinguishing the excitation lamp a predetermined amount of time after the cessation of the laser beam such that damage to the laser apparatus due to overheating is avoided.
