Abstract: A quick connect fiber optic connector assembly for testing and communication that uses a modified ferrule having a reservoir formed into its tip for holding optic transmitting gel or oil. A cleaved optical fiber may be held concentrically within the ferrule for alignment with a receiver or optical device. The gel or oil in the reservoir alleviates the need for a perfect cleave of the fiber and allows for transmission of the optic signal. If necessary, the pressure foot of the connector assembly may be rotated to minimize transmission losses. When the transmission signal is optimized, the fiber may be tested or used for communications. In another embodiment of the invention, a connector assembly includes a removable cartridge housing optical coupling compound. As a bare fiber is passed into the connector it picks up a small quantity of coupling compound and is then interconnected to an optical patch cable.

Abstract: Apparatus for diagnostic analysis of patient-installed pacemaker devices. Patient connection is made via standard ECG leads and an electrically floating front end subassembly having means providing precise gain to the paced ECG input signal and conversion thereof to a digital form via very high rate, monobit delta-sigma modulation digitization. The front end also contains special overload indication circuitry, a reciprocal attenuation network to ensure high fidelity of the information being processed by the system and crystal clock controlled calibration means for providing a validity check of virtually the entire system. A pacer pulse sensing network provides as separate outputs in analog form the on-line, real-time, paced ECG and the individual pulses generated by the pacemaker device.
