Abstract: An adapter for coupling an endoscope to a camera head. The adapter includes a zoom ring, barrel, focusing ring and chassis. A lens, slidably mounted within the barrel, moves axially within the barrel in response to rotation of the zoom ring thereby varying the transmitted size of the image of the proximal end of the endoscope. Rotation of the focusing ring produces axial movement of the barrel within the chassis for focusing the image at the camera head.

Abstract: An ambulatory cardiac monitoring system (10) to event record and monitor ECG signals (20) from a patient (12) for a predetermined time interval. The ambulatory cardiac monitoring system (10) includes a recorder system (18) which is carried by the patient (12). The recorder system (10) is coupled to the patient through leads (16) and electrodes (14) positionally located contiguous to the patient (12). The recorder system (18) includes an analog pre-processor (32), a first microcomputer (34) coupled in a feedback manner to analog pre-processor (32), and a cassette recorder (38). The analog pre-processor (32) has incorporated both automatic gain control and conditioning circuitry that normalizes and filters the basic ECG signal (20). The analog pre-processor (32) produces a plurality of extraction signals which are input to microcomputer (34).

Abstract: An improved assembly is provided of a sealed package, one or more disposable handled swabs or applicator sticks and a medicinal material to be applied by the heads of the swabs or applicator sticks. Where the medicinal material is a liquid, the liquid is substantially completely absorbed by the cotton-tipped heads of the swabs so no body of flowable liquid is present. The package is formed preferably by a tray-forming body of material molded to provide for each swab or applicator stick a well that serves loosely to receive the head portion thereof and isolate it from external compression forces, and an inclined support ledge to position the handle portion thereof so it inclines upwardly and away from the well. A cover sheet of a gas-impervious material is secured over the tray-forming body to provide a gas-tight seal that is selectively openable to provide access to the swabs or applicator sticks.
