Abstract: An inertia switch capable of detecting the arrival of stress waves from any direction in the plane of the mounting surface is disclosed. In a preferred embodiment, a plurality of conductive spheres are held in a plurality of corresponding recesses by spring arms. A pair of interconnected conductors on each recess surface form, with the conductive spheres, an electrical circuit which is broken if any of the spheres is moved outwardly of its recess against the spring by any impact or stress wave in the structure. Provisions are included for adjusting the switch sensitivity by adjusting the spring preload on the spheres.

Abstract: A receiver totally implanted within a living body is inductively coupled by two associated receiving coils to a physically unattached external transmitter which transmits two signals of different frequencies to the receiver via two associated transmitting coils. One of the signals from the transmitter provides the implanted receiver with precise control or stimulating signals which are demodulated and processed in a signal processor network in the receiver and then used by the body for stimulation of a nerve, for example, while the other signal provides the receiver with a continuous wave power signal which is rectified in the receiver to provide a source of electrical operating power for the receiver circuitry without need for an implanted battery.

Abstract: A system of storing digital data on multitrack magnetic records (tape or disc) with extremely high-packing density is described. The input data is encoded into unique four-tert, trilevel zero average format words. Because of the zero average property of the words, an alphabet of 18 zero average words is possible. A parity generator operative on a modulo 18 basis forms a parity word from the input data. This parity word is selected from the available alphabet of ternary words and is recorded in ternary form on one of the tracks in parallel with the ternary words for which it forms a parity check. On playback, the words are decoded and outputs are obtained indicating whether or not the words in each track are valid or invalid. A corrected word generator operative on a modulo 18 basis derives the corrected word and logic is provided for substituting a corrected word for the one of the playback data words which is indicated as being invalid.

Abstract: This invention relates to an expandable truss paraboloidal antenna structure in which the truss structure of the reflector comprises hinged struts that form interconnecting, hinged, triangular truss modules that are aligned in two geometric planes with the struts terminating at junctions on the inner and outer surfaces of the paraboloidal shaped structure. The combination of hinge struts is packaged in a compact unit and then is deployed by being automatically unfolded outwardly by spring means in certain of the hinges.

Abstract: A system for storage on a magnetic record medium (tape or disc) of data with an extremely high packing density is described. Binary input information is encoded into a ternary signal for recording. That ternary signal has spectral properties which facilitate recording with extremely high bit packing density. The ternary signal also contains timing information. On playback the signal is decoded into binary-coded ternary form. Timing information with respect to words of ternary data, as well as the individual terts which make up the words, is also derived. The system includes means for synchronizing the reproduced data in accordance with the timing information derived from the data itself, as well as with an external clock, and decodes the data into the original binary form.
