摘要:
A light emitting diode (LED) warning signal light, the warning signal light comprising an array of light sources configured on a light support and in electrical communication with a controller and a power supply, battery, or other electrical source. The warning signal light provides various colored light signals for independent use or use by an emergency vehicle. These light signals may include a stationary light, strobe light, revolving light, and an oscillating light. Additionally, the warning signal light may be capable of displaying symbols, reverse characters, or arrows. Preferably, rotating and oscillating light signals are produced by sequentially illuminating columns of LED's on a stationary light support. However, the warning signal light may also be rotated or oscillated via mechanical means. The warning signal light may also be transportable for easy connection to a stand such as a tripod for electrical connection to a power supply as a stand-alone warning signal.

A method provides for real-time asset location tracking. An asset in a wide area network, be it a utilities network or a communication network, registers itself with a network management center. The registration process includes identification of a physical location of the asset usable for mapping and tracking the asset.

A wireless communication device (32) within a wireless on-call communication system (10) includes a device receiver (92) for receiving an on-call message (36), a device processor (98) coupled to the device receiver (92) for processing the on-call message (36); a device memory (100) coupled to the device processor (98) for storing the on-call message (36); and an on-call application (108) coupled to the device processor (98) having an on-call schedule (80) for defining an active time period (126) and an inactive time period (128). The device processor (98) processes the on-call message (36) during the active time period (126) and discards the on-call message (36) during the inactive time period (128).

A light emitting diode (LED) warning signal light, the warning signal light comprising a plurality of light sources constructed and arranged with a reflector or culminator, the LED light source being in electrical communication with a controller and a power supply, battery, or other electrical source. The warning signal light provides various colored light signals for independent use or use on an emergency vehicle. The warning light signals may include a strobe light, revolving light, an alternating light, a flashing light, a modulated light, a pulsating light, an oscillating light or any combination thereof. The controller may further be adapted to regulate or modulate the power intensity exposed to the illuminated LED's to create a variable intensity light signal.

A radio communication device enables a message received to be displayed by flexible format. The selective-calling receiver as a receiver comprises a radio section for demodulating the selective-calling signal with it received, a calling number storage section for storing therein a plurality of self-selective-calling numbers, an agreement detector for detecting whether or not demodulated selective-calling signal agrees with which one of the plurality of self-selective-calling signal, a memory for storing therein a plurality of calling separation information for separating whether message information following to self-selective-calling number and selective-calling number agreeing to be detected agree with which one of the plurality of self-selective-calling numbers, a indicator for displaying the message information, and a display measure for permitting message information within the memory to display on the indicator, wherein the display measure permits the message information to display on the indicator in accordance with prescribed display format determined beforehand in every selective-calling number.

An LED array warning light system comprises a plurality of struts in a generally conical configuration. Each strut has an upper and lower edge and an inner and an outer edge. A plurality of light emitting diodes are affixed one above the other to an edge of each strut. A top disk with radial slots receives and is affixed to an upper edge of an associated strut. A bottom disk has radial slots which receive and are affixed to a lower edge of an associated strut. The disks are sized whereby the LED's are at an angle of between 3 and 25 from the axis.

A radio paging receiver with a message display function according to the present invention can display and memorize two or more messages. The radio paging receiver with a message display function comprises a message control unit. The message control unit includes first and second character tables and a message memory. The first and second character tables are for displaying the messages with first and second character types, respectively. The messages stored in the message memory are displayed on the display window in either one of a multiple message display mode or a single message display mode. The message control unit displays the reception messages with the characters of either the first or second character type when the multiple message display mode is selected. When the single message display mode is selected, then only one of the messages is displayed on the window with the characters of the other of the first or second character type.
摘要:
A light emitting diode signal with reduced susceptibility to the “sun phantom” effect. A single printed circuit board populated with both the power supply circuitry and the light emitting diodes is located at an increased distance from the front cover which is angled to direct extraneous light away from the viewers position. A snap together housing reduces overall cost and assembly time. Light from the light emitting diodes distributed across the single printed circuit board to project an overlapping light pattern is collimated by a multiple collimating zone optical element which creates a uniform display aspect without discernable individual points of light.
