Abstract: A telemetry system with a matrixed telemetry switch unit array and a method for determining the switch position of a telemetry switch unit. The switch units include steering diodes and parallel signal paths each with unique resistance values. The signal paths correspond to switch positions and are closed when the switch unit is in the corresponding switch position. A signal source is electrically connected to an input current path and output current path of the array with a corresponding telemetry switch unit coupled into the signal path. A plurality of sensing signals are applied through the array and the resultant signals are measured. The switch position is determined from the resultant signals indicating the resistance value of the switch signal path currently coupled into the array signal path while accounting for the voltage drop of the steering diodes.

Abstract: Electric installation specially created for being built into an agricultural tractor for the purpose of providing an electric power source that may be used by any tool associated thereto to perform a specific task. The invented circuit extends from an alternator that takes energy from the tractor and feeds an external electric circuit including at least one output plug or connector. The alternator may take energy from the tractor's engine through a drive pulley, or from the tractor's power take-up. The invention envisages the use of two alternators, one for the tractor installation and another for the external output circuit, both with built-in voltage regulator, wherein the external output circuit includes electronic converters (capable of generating different output voltages) placed before the external contactors and plugs.

Abstract: A fully monolithic cross-point switch matrix overcomes the isolation problems between unconnected ports of the prior art. An Isolation Enhancement Network (IEN) is connected between each of the input and output transmission lines at each of the cross-points. The switch matrix is comprised of a tiled interconnection of M×N of the 1×1 switch/IEN (SIEN) cells, where N and M are the number of input and output ports respectively. Each of the SIEN cells can be independently configured into one of two operating modes, connected or unconnected. The switching element is configured to provide a high isolation path between the input and output lines in the unconnected mode of operation. In this case, a small fraction of the input signal injected at the input port appears at the output port. This output signal is comprised of two components.
