An improved external visual indicator such as a candle is provided for a gaming machine having lights such as LEDs which are programmable via a processor of the gaming machine. The reprogrammability of the illumination sequence and colors of the candle may provide for the promotion of bonusing and to aid in the servicing of gaming machines. Any assortment of colors of LEDs and combinations thereof may be provided and programmed via the processor of the gaming machine.

A warning beacon includes a transparent housing, having a triangular shape suggestive of a warning sign, the housing having a front face, a back face, and side edges. A mounting plate is disposed within the housing between the front and back faces, and a plurality of LEDs are supported by the mounting plate, and oriented to provide light in at least a forward direction through the front face.

An altimeter has four display panels each being a matrix array of light-emitting diodes. An energizing unit energizes selected diodes to produce a representation of a number in each panel indicative of the value of the input. A knob on the altimeter selects input signals from a barometric source or a radar source. When barometric signals are selected, the altitude is represented in the panels by bright numbers against a dark background. When radar signals are selected, the energizing unit changes the format of energization of the display to represent altitude by dark numbers against a bright background. Other formats are also possible.

A status indicator ( 301 ) in a communication device ( 102 ), such as a cellular telephone, is controlled to visually indicate a plurality of status information during a single indication period ( 602 ). During the indication period ( 602 ), the status indicator ( 301 ) is powered-on for a first predetermined time period (t 1 ) to indicate, for example, no service, in-service or roaming status of the cellular telephone, and powered-on for a second predetermined time period (t 3 ) to indicate, for example, message waiting status of the cellular telephone.

Plural status indication control method suitable for use in a communication device

An electronic display including a first light emitting diode emitting a first color when biased in the forward direction, a second light emitting diode emitting a second color when biased in the forward direction, and means to selectively bias one of the first and the second light emitting diodes in the forward direction so the electronic display emits one of the first and the second colors.

Electronic display having segments wherein each segment is capable of selectively illuminating two colors

An indicating system for a radio receiver is formed of an indicator and associated control circuitry. The indicator is comprised of two emitting diodes wired in parallel and in reverse polarity, and encapsulated in a translucent package. Each diode in an indicator emits light of a visibly distinct wavelength when energized. The control circuitry causes a change in polarity of bias voltage applied to the indicator, and, in so doing a change in color of the indicator. With appropriate control circuitry, the color of the indicator indicates whether the receiver is tuned to an AM or FM station, or whether the station is broadcasting in mono or stereo. The indicator can be mounted to the dial pointer causing a change in pointer color with a change in receiver function. Additionally, the amount of current through the light emitting diodes and thus the intensity of emitted light may be varied in accordance with a parameter variation as, for example, accuracy of receiver tuning.
