Abstract

A programmable graphical display switch that provides users with a simple way of controlling other devices and for customizing how that control is initiated and communicated to the user.

Description

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.

BACKGROUND

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 for 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.

DETAILED DESCRIPTION

Accordingly, several objects and advantages of our invention are as follows. 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 way 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 the 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.

FIG. 1 illustrates the block diagram of the Programmable Display Switch.

A chassis 120 houses a power supply 124, a Display 121, a Display Control and Switch Sensor circuit 122, a control logic circuit 125, one or more relays 123, a programming port 127 and optionally an ambient light sensor 125 and also optionally an audio feedback circuit 126.

The user loads images into a Display Control and Switch Sensor 122 via a programming port 127. The Display Control and Switch Sensor stores the on state and off state images within its memory. While not being touched the Display 121 will show an image that represents its state. Once touched, the Display Control and Switch Sensor will detect the touch and cause the image on the Display 121 to change to its opposite state. Further, the Switch Sensor 122 will command the Control Logic Circuit 125 to change the state of the relay(s) 123 as per the user programming. Power supply 124 provides power to the internal components of the PDS. Ambient light sensor 125 is optional and can adjust the image according to current lighting conditions. Audio Feedback circuit 126 is also optional and can provide the user with audio feedback when the switch is activated.

User programming of the control logic circuit 127 to control the relay(s) 123 can be either latched ON, latched OFF, or momentary. If momentary, then this can further be programmed as to the specific duration.

In some embodiments, the PDS is delivered as a common part number for a switch that can be used in a variety of installations with the image shown on the programmable display and the programmable way of controlling other devices customized for the specific application.

In some embodiments, the invention comprises a switch, comprising: (a) a programmable display, and (b) one or more programmable way of controlling other devices. In some embodiments, the switch is further designed wherein the programmable parameters of the way of controlling other devices can be programmed with the apparatus already installed. In some embodiments, the switch is further designed wherein the programmable display images can be loaded with the switch already installed.
