Abstract: A radio position determation and message transfer system is implemented using a pair of satellites in geostationary orbit for replaying interrogation and replay signals between a ground station and a user-carried transceiver. The user portion is calculated based on the arrival times of replay 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 of the earth's surface. The stored terrain map allows accurate position fixed 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.

Abstract: A junction block is composed of an upper casing accommodating a bus bar distribution board and a lower casing forming an integral connector housing for accommodating a mating connector. The bus bar has integral tabs extending rectangularly to the bus bar and into the connector housing through respective holes formed in the bottom wall of the connector housing. There is provided a deflecting barrier member in the shape of an elongate rectangular bar adjacent an opening which has necessarily been formed in the bottom wall of the connector housing as finished by plastic moulding. In case any water or water drops should creep into the connector housing via the opening in its bottom wall, they are prevented from reaching the tab base zone by the deflecting barrier member which serves to conduct creeping water or water drops downwardly or in the discharge direction. Hence, it will be avoided to cause short circuits or leakage currents to occur between the adjoining bus bars or terminals of the connector.

Abstract: A releasable connector for electric circuits is composed of a male connector housing and a female connector housing adapted to be fittable in each other. One of the connector housings is provided with a resilient short-circuit member while the other is provided with an insulator member. When the two parts are released from each other, the short-circuit member is resiliently urged against the upper surfaces of the terminals in the one connector housing so as to make a short circuit between the terminals. When the two housings are coupled together, the insulator member in the other connector housing wedges in between the short-circuit member and the terminals in the one connector housing so as to break the short circuit made therebetween.
