A touch-sensitive display device includes a display. A transparent plate is provided in front of the display. A tactile sensor senses a touch event. One or more infrared sensors are positioned in front of the transparent plate. The one or more infrared sensors identify a location of the touch event when the tactile sensor detects a touch event.

Infrared touch screen gated by touch force

The present invention discloses a color CRT system that can be easily adapted for installations in either the northern or the southern hemisphere. The CRT is symmetrical with respect to its yamming or set up for the earth's magnetic field so the CRT can be installed in either a normal or an inverted orientation. Likewise the yoke and yoke connector are designed and can be easily installed so the CRT scan starts in the upper left of the CRT in either the normal or inverted installation. The connectors for the neck video card are designed to exit the side of the card so the wires can be routed to the CRT system card in either CRT installation orientation. Finally the anode wire is made with a length and attachment point such that the anode is wireable when the CRT is in the normal or inverted orientation. Also disclosed are visual orientation markings on the CRT, the yoke and yoke connectors and the neck video card connectors so it is easy to visually see when all elements are correctly installed for either the northern or the southern hemisphere installations.

Multi-hemisphere color CRT

The present invention discloses a method and system for controlling a system display from the processor controlling a fiscal printer. The system display is controlled by generating an overlay image in a storage device along with overlay image selector data. The overlay image selector data is used to control modifying circuits that can substitute or otherwise modify, with overlay image data, all or a portion of the system display image generated by application software. Since the fiscal printer hardware and firmware is not a part of the particular application software running on a point of sale device the control function of the fiscal printer need not require modification of application software or hardware.
