ABSTRACT:
The clock device has a hollow housing bearing readily viewable adjacent first, second and illuminatable display panels, the first panel bearing the hour indicator and an inverted V indicating zero, four dots indicating ones and two horizontal bars each indicating five, the second panel being the tens of minutes indicator and bearing four dots and one horizontal bar, while the fifth panel is the minutes indicator and bears an inverted V, four dots and one horizontal bar. A power supply such as electrical house current or a battery is disposed in the housing, connected to a clock timing mechanism and a signal generator which is, in turn, connected to symbol-illuminating incandescent bulbs, liquid crystal display components and/or light emitting diodes in the panels. The device can also include a similar temperature measuring and display mechanism, with separate fourth, fifth and sixth display panels bearing mayan symbols, and + and - symbols, with switches to cause the device to alternately or simultaneously display the time and temperature. Alternatively, the temperature display can be made on the first three panels.
