Patent number: 7236101Abstract: A warning system for making known the presence of an emergency vehicle. A transmitter is mounted in an emergency vehicle that outputs a digital UHF/LMS signal that is detectable within a range. A receiver responds to the digital UHF/LMS signal from the transmitter and is mounted, most preferably to a dashboard of a motor vehicle. The receiver detects from the digital signal the type of emergency vehicle from which the digital signal is originating. In one embodiment the digital signal also includes a unique identifier for the transmitter rather than simply a generic discipline identifier such as police, fire, emergency etc. A visual indicator mounted to the motor vehicle is activated in response to the digital signal from the transmitter to warn a motorist in the motor vehicle of a presence of the emergency vehicle within the range of the transmitter and to warn the transmitting vehicle of the presence of other emergency vehicles within receiving range.Type: GrantFiled: March 25, 2004Date of Patent: June 26, 2007Inventor: Richard T.

Patent number: 7230546Abstract: An apparatus and method for generating incursion alerts in response to incursion events detected by incursion detector units, attached to safety icons such as traffic cones and signage. The incursion detector units are activated by automatic activation sensors and remain activated for a period of time. Alerts are generated in response to impacts detected at the safety icons by an incursion detector and transmitted to one or more incursion receiver units which annunciate the alert with audio, lights, or tactile output to warn personnel of possibly impending danger. Alert signals are preferably repeated by other incursion detectors wherein the distance and conditions over which the alert signals may be communicated is extended. A validation circuit and tilt sensor filter out not incursion events such as wind tipping. The incursion detectors may generate area alerts, or personal alerts and can transmit operational status and alerts to discrete groups of receivers.Type: GrantFiled: January 6, 2005Date of Patent: June 12, 2007Inventors: Craig Nelson, Robert Bos

Patent number: 6965203Abstract: Disclosed is a method and circuit for repetitively firing a flash lamp. The method utilizes a power supply having a periodic voltage signal. The method times the discharge of the flash lamp to occur when the power supply signal is below the flash lamp self extinguishing voltage such that the flash lamp de-ionizes while the power supply signal remains below the self extinguishing voltage, thus preventing afterglow. The circuit utilizes a means for detecting when the voltage of the power supply voltage signal falls below the self extinguishing voltage to trigger the flash lamp. An additional embodiment adds a means for interrupting current flow in the flash lamp before the voltage across a storage capacitor falls below said self extinguishing voltage. The method and circuit may be extrapolated for use with other electromechanical devices.Type: GrantFiled: September 17, 2003Date of Patent: November 15, 2005Assignee: Synaptic Tan, Inc.Inventors: David G.

Patent number: 6714140Abstract: Signal light having first and second identical electrical cells, each having the necessary capacity to last for a standard operating cycle. The cells are electrically connected by means of a bistable switch to an electronic control circuit in stable alternative and nonalternating fashion until they are individually depleted. The electronic control circuit has one output connected to one corresponding signal light and another two outputs connected to individual light indicators which are light emitting diodes respectively assigned to the first and second electrical cells and activated by the electronic control circuit when the latter detects a depletion of the electrical energy of same.Type: GrantFiled: January 23, 2001Date of Patent: March 30, 2004Assignee: Celaya, Emparanza Y Galdos, S.A. (CEGASA)Inventor: Jesús María Eguiluz Fernandez

Publication number: 20040056777Abstract: The invention describes an optical signal transmitter device, in which a specific, predetermined emission characteristic or light density distribution is achieved solely by the arrangement of two or more light elements on a base plate. This means that there is no longer any need for complicated optical structures in order to produce the predetermined light distribution. The invention furthermore describes an optical signal transmitter device that uses a convex condenser in order to improve the light gathering characteristic.Type: ApplicationFiled: June 23, 2003Publication date: March 25, 2004Inventor: Simon Blumel

Patent number: 6707389Abstract: 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.Type: GrantFiled: September 24, 2002Date of Patent: March 16, 2004Assignee: 911EP, Inc.Inventor: John C. Pederson
