    Abstract: PROBLEM TO BE SOLVED: To intuitively locate articles. SOLUTION: An object locator system generates an audio signal, as if it is emanating from the object, as a user varies angular orientation and distance from an object or site to be located within an area. A computer linked to an access transceiver receives transmissions from a user wearing a headset including a transceiver and electronic compass. The compass provides a signal indicative of the user orientation. An access transceiver receives the signal, and calculates the location of the user based on the time difference of arrival of the RF signal and triangulation of the user movement. Based on the angular orientation, as well as horizontal and vertical distance of the object or site relative to the user, the computer maps the location information into sound in the form of pulse amplitude or frequency modulated sound. The audio signal is perceived by the user as emanating from the object or site. COPYRIGHT: (C)2003,JPO

    Abstract: PURPOSE: To provide a symbol scanning system which reads a symbol such as the bar code and suitably changes the pattern of a light beam in response to a feedback signal. CONSTITUTION: A symbol scanning system which suitably changes scanning system parameters containing the pattern and focal point of a light beam so as to improve readability of bar codes is provided with a scanner which directs the light beam toward a symbol at a prescribed position in a certain pattern in response to a coordinate control signal, detects the reflected part of the light beam, and generates the feedback signal corresponding to the detected part of the reflected light beam, a microprocessor 10 which generates a pattern control signal in response to the feedback signal, a pattern generator 20 which generates the coordinate control signal and decides a light beam pattern in response to the pattern control signal, and a signal processing circuit including a drive control unit 40A for adjusting the threshold levels of gains, band widths, and a digitizer.

    Abstract: PURPOSE: To provide a highly practical and reliable and inexpensive hand-carry type scanning device for using a non-laser light source without errors. CONSTITUTION: A light beam is radiated from a light emitting diode so as to read a symbol, a bar code symbol for instance, and reflected light returned from the symbol is received. An optical system inside this scanning device converges the visual field of the light beam 11 and a photosensor 17 to different two planes present at the outside of a housing. A device for image-forming a vision checking window is installed inside the scanning device and the area of the vision checking window is smaller than the one of a scanning spot. The scanning device uses the light emitting diode (LED) 10 as the light source, and since the LED 10 views only the part of the scanning spot viewable through the vision checking window, the scanning spot of the relatively large size (about several millimeters) of the LED 10 is used without sacrificing read performance.

    Abstract: An object locator system (100) generates an audio signal as if emanating from the object (118) as a user (102) varies angular orientation and distance from an object (118) or site to be located within an area. A computer (106) linked to an access transceiver (110,112) receives transmissions from a user (102) wearing a headset (104) including a transceiver (202) and electronic compass (122). The compass (122) provides a signal indicative of the user orientation. An access transceiver (110,112) receives the signal and calculates the location of the user (102) based on the time difference of arrival of the RF signal and triangulation of the user movement. An accelerometer (204) in the headset (104) continuously tracks user movement. The location of the object (118) in a vertical direction is provided by a directory or other reference source stored in the computer (106). Based on the angular orientation, horizontal and vertical distance of the object (118) or site relative to the user (102), the computer (106) maps the location information into sounds in the form of pulse amplitude or frequency modulated sound. The audio signal is perceived by the user (102) as emanating from the object (118) or site.
