Abstract

To prevent false indications of position, a primary sensing panel having a plurality of primary switches such as infrared beam switches or touch switches is operated in conjunction with a manually operable pressure sensitive switch which is attached to a finger of the user by an elastic band or forms part of a probe and only permits position determination when it is in positive contact with the panel. An audible signal may be given at such time. The pressure switch signal may be via wire or radio transmitter on the user's wrist; the transmitter may provide coding to prevent unauthorised use of the panel. <IMAGE>

Description

SPECIFICATION A switching unit This invention relates to a switching unit particularly for touch display switching associated with information displays.
There is an increasing need for, and usage of, transparent overlay switches for message panels such as cathode ray tubes, plasma, liquid crystal display and vacuum fluorescent. Currently, two technologies dominate the field.
a) an array of infrared beams overlaying the display; b) a sandwich of plastics and indium tin oxide layers which conduct when pressed together.
System a) is excellent for non-interference with the display of information but lacks feel and can cause false operation due to unwitting interruption of the beams.
System b) gives more feel but causes large amounts of spurious reflection and worsening of the displayed information.
The biggest problem with the infrared type switch is that it needs no activating force and simply requires the insertion of a finger, or extraneous object, into the matrix of beams for the switch to activate. As the beams are invisible, this can cause many false operations. In ultra-safe areas such as air traffic control, such false operation is totally unacceptable.
Object of the invention It is the main object of this invention to provide a secondary switching unit for use with either of the above systems but with particular reference to the infrared system.
Statement of invention According to the present invention there is provided a secondary switching unit for use with a primary switching panel having a plurality of primary switches, said secondary switching unit comprising a pressure operable switch and means for enabling the pressure operable switch to be manually operated, the pressure operable switch being connected to effect the operation of a selected one of the primary switches when the pressure operable switch is operated by pressure applied to the selected primary switch through the pressure operable switch.
The pressure operable switch may be attached to the end of a finger of the user by a band of elastic material.
The said connection may be by a wire or by the use of a radio transmitter.
Drawing The accompanying drawing is a diagrammatic view of a switching unit in accordance with the invention fitted to the finger of a user.
Specific description The drawing illustrates a secondary switching unit having a pressure operable switch 1 of known construction attached by an elastic bend 2 or the like to the end of the index finger 3 or other finger of the user. The pressure operable switch projects from the pad of the finger and is connected by a wire 4 either directly to whatever unit is being switched or to a radio transmitter for sending a signal to operate such unit. If a transmitter is employed, this is conveniently strapped to the wrist of the user.
In use with an infrared beam system, the finger with attached pressure operable switch 1 is placed in the beams which are in turn software controlled to allow the selection of multiples of choice by moving the finger about. At such time as the definite choice is made, the finger is pressed down activating the pressure operable switch 1 and sending an impulse to the system to indicate choice. By using a small radio transmitter, the signal can be coded so that only authorised personnel can make the required choice. This eliminates the possibility of false operation which is inherent in all other systems. In this manner the use of infrared beams gives the best possible display and the use of the remote pressure operable switch and a secondary switching unit defines a specific choice.
An audible signal may be used to indicate completed action to the operator.
Alternatively to the pressure operable switch being attached to the end of a finger of the user, it may be attached to the end of a probe to be manually operated by the user.

Claims (8)

1. Asecondaryswitching unitfor use with a primary switching panel having a plurality of primary switches, said secondary switching unit comprising a pressure operable switch and means for enabling the pressure operable switch to be manually operated, the pressure operable switch being connected to effect the operation of a selected one of the primary switches when the pressure operable switch is operated by pressure applied to the selected primary switch through the pressure operable switch.
2. A switching unit as claimed in Claim 1, in which the pressure operable switch has an elastic band attached thereto which enables the pressure operable switch to be connected to a finger of the user.
3. A switching unit as claimed in Claim 1, in which the pressure operable switch is fixed to the end of a probe to be manually operated by the user.
4. A switching unit as claimed in Claim 1, in which the pressure operable switch is directly connected by a wire to the primary switching panel so that a selected primary switch is operated when pressure is applied to the said primary switch simultaneously with the actuation of the pressure operable switch.
5. A switching unit as claimed in Claim 1, in which the pressure operable switch is connected by a wire to a radio transmitter for sending a signal to actuate the primary switching panel so that a selected primary switch is operated when pressure is applied to the said primary switch simultaneously with the actuation of the pressure operable switch.
6. A switching unit as claimed in any one of the preceding claims, in which the primary switches operate on the infrared beam system.
7. A switching unit as claimed in any one of Claims 1 to 5, in which the primary switches are pressure sensitive switches.
8. A secondary switching unit substantially as herein described with reference to the accompany- ing drawings.
