Programmable Display Switch

1. Field of the Invention

This invention relates to an apparatus for controlling and managing the control of devices and communicating the function or device being controlled to the user.

2. Description of Related/Prior Art

In existing switch technologies the function of the switch is often predetermined and an associated label affixed to the switch that represents its function.

For example, in an aircraft environment, this would amount to hundreds of different part numbers being created, maintained, spared and then certified by the Federal Aviation Administration as safe.

There remains, therefore, a need fur a programmable switch that is capable of duplicating the functionality of many other switches, while providing sufficient flexibility to convey its purpose to the user.

Accordingly, several objects and advantages of our invention are:

• Our programmable display switch (PDS) provides a minimum of one user programmable relay that allows for controlling other devices. The programmable features include but are not limited to: latched or momentary operation. If momentary then the duration is also programmable. Our PDS includes a user programmable visual display element such as an Organic Light Emitting Diode (OLED) display panel. This display panel is user programmed with different graphics that represent the state of the associated relay.
• Our PDS allows for graphics displayed on the visual display panel to be changed by the user even after the PDS has been installed into the target application.
• Further objects and advantages of our invention will become apparent from a consideration of the drawings and ensuing description.

The invention, a programmable display switch, provides users with a simple means of controlling other devices and for customizing how that control is initiated.

A display panel is connected to a display controller where the user downloads the desired switch state images. When the user wants to change the state of the switch they touch the PDS and switch sensor will detect the touch and change the state of the switch as per the user programming.

For example, if the PDS is being used as a heater control, the ON image may be one of a heater with radiating lines coming from it while the OFF image is one with no lines.

• If the heater is currently off, the image could be the current OFF state, in which case when the user touched the PDS the image would change to ON and the relay(s) would either open or close or be latched or momentarily change state depending upon the user program and the requirement of the device being controlled. If at some later date the user no longer liked the heater image with lines they could simply load a new image into the PDS without removing it from its currently installed position.
