摘要： Driverless vehicles move in one direction along elongated, lengthwise adjacent radiators that are energized with command signals to which the vehicles respond. The radiators are grouped in lengthwise adjacent blocks. A radiator just in front of each block boundary and another just behind it are energizable alternatively through a bistable switch device. A vehicle crossing a block boundary generates a control signal which actuates the switch device for that boundary, transferring energization from the radiator just behind the boundary to the one just ahead of it, so the vehicle can advance into the block in front of the boundary. Boundary crossing also actuates the switch device for the boundary behind the vehicle, to enable a following vehicle to approach the block the first vehicle is leaving.

摘要： A target has pairs of penetrable electrical conductive sheetlike elements that are flatwise opposed and spaced apart a distance to be transiently electrically connected by a penetrating projectile. Each pair corresponds to an annular scoring zone. Elements for radially outer scoring zones are on a permanent front sheet-like structure; those for inner ones are on a readily replaceable sheet-like structure installed behind the front one. To accommodate possible misalignment of the sheet-like structures the radially innermost elements on the front structure partially radially overlap the radially outermost ones on the rear one. Such overlapping elements cooperate for one scoring zone, and corresponding ones of them on the two structures are electrically interconnected.

摘要： In a remote control system wherein control commands are sent as telegrams, each containing a fixed number of binary bits, transmission of each telegram is required to span a time interval divisible into equal periods, the number of such periods being equal to the number of bits in a telegram, and each bit pulse being required to persist for a predetermined portion of the duration of its period. Preferably the last pulse of each telegram has a longer duration than the others. The long last pulse is utilized for telegram framing as well as for authenticating received telegrams.
