Abstract: A curved-surface cassette/gel system is disclosed in which the walls of a cassette and the major surfaces of a slab-shaped electrophoresis gel in the cassette coact to substantially exclude liquid or gas from between either wall and the major surfaces of the gel. Exclusion is accomplished by exerting a normal force at all points on the walls of the cassette and at all points on the major surfaces of the gel. A curvature may be present in at least one wall of the cassette and in at least one major surface of the cassette. A cassette headpiece may be divided by septa which form an edge seal with the slab gel. The spaces formed between the septa function as wells into which sample materials may be placed.

Abstract: A radio position determination and message transfer system is implemented using a pair of satellites in geostationary orbit for relaying interrogation and reply signals between a ground station and a user-carried transceiver. The user position is calculated based on the arrival times of reply signals received at the ground station via the two satellites, the known transmission time of the interrogation signal from the ground station, and the user's elevation on the surface of the earth. The elevation is derived from a stored terrain map providing local terrain elevations at a plurality of points on the earth's surface. The stored terrain map allows accurate position fixes to be obtained for surface users regardless of the deviation of the local terrain from the spherical or ellipsoidal model of the earth's surface.
