An apparatus is disclosed for uniformly biasing a transducer against a human eye comprising an outer housing, an inner housing insertable into the outer housing and a biasing means. The inner housing has attached thereto a transducer and is movable with respect to the outer housing between an extended position and a retracted position. Bushing means are provided between the respective housings to maintain such housings in a concentric relationship and also to reduce friction between the respective housings. The probe is adapted to be applied against an eye and maintain substantially constant pressure on the eye, hand motion being compensated for by the biasing means, illustratively a spring.

A scanning apparatus and method for scanning an object including a frame, a transducer for obtaining information from an object and a motor oscillating the transducer. The motor comprises a spring/solenoid combination driven at the resonant frequency of the spring/motor system. The actual displacement of the transducer is measured and compared to a desired displacement to provide a control signal to the motor. The scanning apparatus is at least partially enclosed by a housing containing a heat transfer fluid for damping the resonant vibration of the apparatus.

A pacemaker training aid for use in explaining the conduction system of the heart and the therapy provided by the use of a pacemaker, utilizes an illustration of the heart having lights associated therewith to show the sequence of transmission of command signals that normally cause proper action of heart chambers; the sequence of transmission of command signals usually present during improper or abnormal operation of the heart; and the effect of a pacemaker on such irregularities. The lights are mounted at various predetermined locations on or behind the illustration in order to simulate the location of various physiological entities; the illustration is usually in the form of a color transparency. A means for controlling the sequence of illumination is provided. The sequence is determined by the normal or irregular cardiac condition which it is desired to illustrate. The placement of a pacemaker and its effect on the cardiac condition or the operation of the heart may also be illustrated, by use of a dummy pacemaker and electrode which can be attached to the training aid during the training session and an illumination sequence control which illustrates the pacemaker's effect on the heart's operation.
