Abstract: A method of calibrating an analyte sensor in vivo, by providing a first predetermined stimulus to the sensor when the sensor is applied to a subject to produce a first sensor signal, measuring the first sensor signal, and determining a calibration function based on the first measured sensor signal resulting from the predetermined stimulus. The calibration function, when applied to further signals received from the sensor, can be used to provide a calibrated output.

Abstract: A pet cage provided with a barrier made of a plurality of thin, flexible plastic or metal wires stretched between a cage top and base which are spaced apart by a support post. The thin wires are effective as a physical barrier and practically do not block the passage of light or airflow to and from the cage interior. Thus, the inventive pet cage barrier enhances the pet owner's enjoyment by Improving the balance between the confining and visibility functions of the cage. The flexible nature of the pet cage barrier allows the cage to be packaged in a folded, compact fashion which is easily transported, and the simple design enables quick assembly, both desirable features unavailable in existing cage designs.

Abstract: Apparatus includes a mounting member having a bore which closely receives the shaft and a counterbore in which two elastic O-rings separated by an annular element are received. A first compression member threadably engages the mounting member to apply axial pressure to the O-rings, which are radially compressed against the shaft by bevelled annular surfaces which capture the O-rings. This provides an environmental seal effective for a vacuum while still permitting axial and rotational movement of the shaft. Apparatus further includes a ball member fixed to the mounting member and received against an O-ring in a socket member. A second compression member threadably engaging the socket member to urge the ball member against the seal to provide additional sealing while permitting pivotal movement of the shaft.

Abstract: A sealed shaft for use in an evacuated chamber in which the shaft can be moved by control from outside the chamber while maintaining the seal around the shaft.

Abstract: An improved method is provided for the visual inspection of printed circuit boards to determine the continuity or discontinuity of the circuits. In the method the circuit boards are treated in an electrolytic bath to cause an electrochemical change in the color of the continuous circuits versus the discontinuous circuits.

Abstract: An improved method of assembling components on printed circuit boards whereby trimmed component leads are placed into holes in the printed circuit board, and an extrudable, non-flowing, heat resistant, completely water soluble mixture is applied over and around the components to keep them in place. The components are then soldered to the board and the extrudable mixture washed away with water. The mixture is made from a solid polyalkylene glycol, an alkali metal soap, glycerine and water.
