US Classification:

250205, 2502211, 250223 R, 186 59

Abstract:

A self-calibrating photoelectric control system for use in a checkstand to control the starting and stopping of a conveyer belt utilized to move products closer to a checkout clerk. The self-calibrating photoelectric control system including a light source for emitting a light beam having an intensity, a photoelectric sensor for receiving light from the light source and for generating an output signal when the received light is equal to or greater than a light-state threshold of the photoelectric sensor; and a calibration circuit for automatically calibrating the sensitivity of the photoelectric control system to partial beam breaks after occurrence of any one of a plurality of predefined events. The calibration circuit is operative for performing a calibration process which adjusts the intensity of the light beam emitted by the light source such that the intensity is slightly greater than the light-state threshold of the photoelectric sensor. By repeatedly performing the calibration process at selected times, the present invention optimizes the detection of objects that partially block the light beam, and thereby greatly enhances the system's ability to detect translucent and low-profile products.

Appl. No.:

10/715849

Inventors:

Robert Warner - New Port Richey FL, US

International Classification:

B66B013/26

US Classification:

187317000

Abstract:

An elevator door closure control system and method are provided and include an elevator light screen signal detector module having first and second electrical connectors, a signal detection element configured to detect a carrier wave control signal and output a signal in response thereto, and a switch configured to change from a first state to a second state (or vice versa) in response to a signal detection element output signal or a control signal from a controller. The electrical connectors permit connection of the module to a light screen receiver array output and an elevator door controller input so as to place the switch in series with the receiver array output. The switch second state causes, in one aspect, the elevator doors to remain open for a preset time or until the light source array detects the arrival of an appliance, person, or object in its beam path(s).

Appl. No.:

8/631882

Inventors:

Robert A. Warner - Oldsmar FL
Grant L. Smith - Lutz FL

Assignee:

Tri-Tronics Company, Inc. - Tampa FL

International Classification:

G01J 132
H01J 4014

US Classification:

250205

Abstract:

The disclosed invention is a photoelectric sensor that is capable of resolving difficult low contrast sensing tasks by adjustment of the sensor's light source intensity, so as to prevent dark state saturation and extend the overall dynamic range of the sensor. The photosensor utilizes an enhanced dynamic (EDR. TM. ) control circuit that combines the light source and offset adjustment of the DC amplifier circuit in a closed loop configuration. This connection provides an automatic reduction in the light source intensity as required to avoid saturation. Further, this is accomplished without sacrificing amplifier gain, so that the dynamic operating range of the photosensor is extended to include proper operation at very bright light levels. The EDR control circuit also includes an indicator circuit that is connected to the light intensity control circuit. The indicator circuit provides the user an indication of where in the overall dynamic range of the photosensor the offset adjustment of the DC amplifier has been set.

Appl. No.:

6/627853

Inventors:

Robert A. Warner - Clearwater FL

Assignee:

Tri-Tronics Company, Inc. - Tampa FL

International Classification:

G09G 300

US Classification:

340753

Abstract:

A photoelectric sensing system, the adjustment of which is facilitated by the incorporation therein of a contrast indicator with a display in the form of an array of light emitting diodes (LEDs) controlled by a driver circuit which is arranged for successive illumination of the LEDs, preferably on a one-to-one basis. This bargraph type instrument is also effective in photoelectric sensing tasks involving variations of the detected light between "light" and "dark" at a rapid rate, in which case the range of LEDs between these two extremes appears dimly lit at a steady glow.
