A flexible CNC-multiposition measuring installation, which represents a combination of components from the coordinate measuring technique with elements from the multiposition measuring technique and the counter testing technique, which are joinable with each other in a common measuring installation. Such CNC-multiposition measuring installation are, in particular, adapted for the integration thereof into a manufacturing or production process.

Flexible CNC-multiposition measuring installation

To permit external programming of the decoding of outputs from a binary counter, a polarized power supply is connected, selectively, through a plurality of control gates to the counter, the control gates having transfer switch characteristics and, in dependence on their connection to the specific polarity of the power supply, provide decoded outputs representative of specific count states of the counter to enable further AND-function gates in accordance with the decoded outputs and thereby permit selection of selected loads if other inputs to the AND-function gates are also enabled.

Externally controllable binary interrogation and decoding circuit,

A plurality of receivers which can be respectively addressed by addressing pulses provide reply pulses on a separate reply signal bus indicative of a single digit, or multi-digit binary response condition. To permit extended indication, the central station includes a holding stage which holds the output received from the reply receivers for the duration of a selection cycle during which the plurality of loads can be addressed, for example during a predetermined counted number of such cycles or during a predetermined counted number of pulses to permit averaging-type instruments to respond to said number of pulses --if present--or to permit extended indication of single digit binary output--if present.

Remote control addressing and reply indicating system

A central station is connected to a ring bus system to which a number of separately addressable loads are connected through specific load receivers. The central station has a switching system by operation of selected switches of which, specific loads can be addressed. The ring bus system has a power line or bus, a clock line or bus, and a control line or bus. The clock line provides clock pulses during a selection cycle, and upon coincidence of a clock pulse with a pulse on the control bus, a specific load associated with a predetermined numbered pulse on the clock line can be addressed by sensing coincidence of the pulse on the control line and on the clock line. To separate selection cycles, a control signal is transmitted which may form a pause of clock pulses on the clock line. This control signal, in accordance with the invention, is represented by a series of pulses transmitted on a line other than the clock line, for example on the control bus. It is generated by a pulse generator in the central station to supply a predetermined number of such pulses on the control line only. The receivers have suitable receiver counters which respond to these pulses. Logic circuitry can distinguish between the selection pulses, which will have coincidence on the clock bus and on the control bus, and clock pulses which will appear only on the clock bus. The synchronization pulses are of a predetermined number which will appear only on the control bus so that the respective function synchronization counters in the central station and in the receiver will be synchronized anew for each selection cycle by digital evaluation of the function synchronization pulses.

Remote control system for selective load switching, specifically for

To mount control switches for convenient operation by the operator of motor vehicles, a cantilevered, free standing multi-faceted elongated hollow box like structure is secured to the steering post housing so that it is located between the steering wheel and the dashboard, spaced from the dashboard. A plurality of touch-sensitive switches are located on the surfaces of the structure defined by the facets thereof. The structure includes printed, or integrated circuits to which the switches are connected which, in turn, are attached to a cable which is separably connected to the cabling of the vehicle. Preferably, discrete switch functions, such as headlight energization, windshield wiper controls, and the like are mounted on discrete, different surfaces of the box like structures, whereas similar functions with different control effects, such as windshield wiper speed can be mounted on the same surface, so that erroneous operation of a switch will not initiate an erroneous function, but at best only an erroneous mode of operation of the selected function.

Switchbox and control unit assembly for automotive vehicles

Two surface electrodes are applied to an insulating substrate. The surface electrodes are totally surrounded by a metallic shield which is electrically floating, one of the electrodes being an emitter electrode emitting ac radiation and the other a receiving electrode. A portion of the emitted field is conducted by the shield. Upon approach, or touching of the shield by a grounded body, for example by the hand of a user, the field distribution within the shield will change and the radiation received by the receiving electrode will likewise change. In accordance with the present invention, an integrated circuit (IC) evaluation circuit is located beneath the metallic shield on the insulating substrate, the surface electrodes as well as external terminals passing through the insulated substrate being connected to the IC. Preferably, the shield is a plastic cap which is metallized, formed with snap tongs to snap over the insulated substrate.

Proximity switch and circuit system

A central station generates grouped clock pulses in recurring selection cycles, separated from each other by an extended control pulse (or pulse gap); particular loads are associated with particular counts of a central counter in the central station. The separate counts of the counters are connectable to a control bus of a combined power bus, clock bus and control bus cable system which passes by all the loads associated with the power supply. At the loads, receiving counter step in synchronism with the pulses occurring during the selection cycle. Specific loads are assigned specific count numbers and when coincidence between the count, as stepped by the counter and a pulse on the control bus, (as controlled by a switch setting at the central station) occurs, switching function, such as connection, or disconnection is effected at the load. An additional answer back line may be included in the cabling system, likewise connected upon stepping of the counter and recognition of the specific count associated with any receiver, connecting the receiving reply signal generator for example a sensor or transducer to an indicator at the central station, specific indicators being associated with specific switches at the central station.

Combined on-board remote control energy supply distribution and

The inductance of a coil wound on one end of an elongated rectangular core with an elongated central window is caused to vary by the displacement of a conducting plate or ring arrangement lengthwise of the core. The other end of the core may also be wound with a coil to produce a differential type of transducer. The elongated core may be bent around into a circle in order to provide a transducer for rotational displacement. Additional ferromagnetic bodies in fixed relation to the core or to the short-circuiting rings can be used to modify the translation characteristic.

Inductive transducer for rectilinear or rotational displacement

A leakage field capacitor has two adjacently located surface electrodes placed on an essentially plane support surface. A signal source is connected to one of the electrodes, so that this electrode, which may then be termed the transmitting electrode, will provide an electrical field which is sensed by the other, receiving electrode, which is connected to an evaluation circuit which evaluates disturbance of the field generated by the transmitting electrode. A metallic shield which is electrically floating i.e., is galvanically isolated with respect to the electrodes is connected to the signal source as well as to the evaluation circuit in such a manner as to draw off a portion of the field generated by the transmitting electrode when a mass connected to a terminal of the electrodes -- for example ground of chassis -- approaches the shield to cause an increase in leakage field being drawn off by the shield and thereby provide a positive signal indication; the grounded mass may, for example, be the finger of a user operating a switch.
