摘要： A laser bar code symbol scanner embodying a narrow band-pass optical filtering system of novel construction. A first optical filter element is installed over the light transmission aperture of the scanner housing, and has wavelength selective properties which transmit only light having wavelengths from slightly below a predetermined wavelength in the visible band of the electromagnetic spectrum (e.g., greater than slightly below 670 nanometers). A second optical filter element is installed within the housing, along the focused laser return light path between the light focusing element and the light detecting element, and transmits only light having wavelengths from slightly above the predetermined wavelength (e.g., less than slightly above 670 nanometers). Collectively, the first and second optical filter elements cooperate to form a narrow wavelength band-pass filtering system centered about the predetermined wavelength, providing improved signal-to-noise ratio. As a result of the present invention, aesthetically unappealing electro-optical components mounted within the scanner housing are hidden from plain view, while the optical filtering elements of the system can be easily and inexpensively manufactures and used without compromising the signal-to-noise ratio performance of the laser scanner.

摘要： A laser bar code symbol scanner employing a narrow band-pass optical filtering system of novel construction is disclosed. A first optical filtering element is installed in the light transmission aperture of a bar code scanner housing. A second optical filtering element is installed inside the scanner housing near the light detecting element. The first and second optical filtering elements have wavelength selective properties such that taken together they cooperate to form a narrow wavelength band-pass optical filtering system which allows only transmission of light at and around a certain predetermined wavelength into the photodetector element. The present invention also hides aesthetically unappealing electro-optical components mounted in the scanner housing from plain view and the optical filtering elements of the system can be easily and inexpensively manufactured without compromising the performance of the scanner.

摘要： A novel optical filtering system for a laser bar code scanner having narrow band-pass characteristics is disclosed. The optical filtering system has two different optical filtering elements which are disposed in a scanner housing in a spatially separate relationship. One of the optical filtering elements is positioned inside of the scanner housing in front of and close to the light detection element. The other optical filtering element is positioned in the light transmission aperture of the scanner housing and forms the scanning window. The optical filtering characteristics of the scanning window obscure the internal components of the scanner from plain view making the scanner appear more aesthetically pleasing. Together the optical filtering element cooperate to form a narrow-band pass filter to provide for better light collection and scanning.

摘要： Method and apparatus for automatically reading bar code symbols using a reading device containing a laser beam configured to provide a scan field. The method involves automatically detecting the presence of a bar code within the scan field by flickering the laser beam. In automatic response to the detection of a bar code, the automatic bar code symbol reading device generates a laser beam scanning pattern and reads the detected bar code by producing scan data signals from the detected bar code and thereafter collecting and analyzing these data signals. Further aspects of the present invention relate to hand-holdable data collection devices adapted for use with the automatic bar code symbol reading device to form a portable symbol reading system characterized by versatility and simplicity of use.

摘要： The invention is a method and apparatus for automatically reading bar code symbols. One aspect of the present invention concerns a method of reading bar code symbols using an automatic hand-holdable bar code symbol reading device. In general, the automatic bar code symbol reading device comprises a hand-holdable housing containing operative elements which provide an object detection field and a scan field each defined external to the housing. The method involves automatically detecting the presence of an object within the object detection field by sensing object sensing energy reflected off the object. In a preferred embodiment, the object sensing energy is IR radiation produced from an object sensing energy source disposed within the housing. In automatic response to the detection of the object within the object detection field, the hand-holdable device detects the presence of a bar code within the scan field using a laser beam produced within the housing. Then, in automatic response to the detection of a bar code in the scan field, the automatic hand-holdable bar code symbol reading device reads the detected bar code in the scan field by producing scan data signals from the detected bar code and thereafter collecting and analyzing the same. Another aspect of the present invention concerns a hand-holdable data collection device adapted for use with the automatic bar bode symbol reading device to form a portable symbol reading system characterized by versatility and simplicity of use.

摘要： A laser beam experimentation kit, including an accessory device for modulating the intensity of the visible laser beam produced as output from a laser pointer. The accessory device comprises a printed circuit(PC) board of physically thin construction, which is adapted for slidable insertion between the conductive tip portion and the conductive housing portion of a pen-clip actuatable laser pointer. A pair of conductive pads are formed on the upper and lower surfaces of the PC board. An input signal jack is mounted on PC board for the purpose of receiving a mated plug connector that is connected to a flexible cable carrying an electrical input signal. An electronic circuit and a battery power source are also mounted on the upper surface of the PC board. The function of the electronic circuit is to respond to a predetermined signal characteristic (e.g., the amplitude, frequency or phase) of the input signal supplied to the input signal jack, and to provide a variable load between the pair of conductive pads formed on the PC board. In this way, when the PC board is slidably inserted between the conductive tip portion and the conductive housing portion of the pen-like housing of the laser pointer, the pair of conductive pads on the PC board automatically establish electrical contact therewith without problems of alignment or the like.

In this way, when the PC board is slidably inserted between the conductive tip portion and the conductive housing portion of the pen-like housing of the laser pointer, the pair of conductive pads on the PC board automatically establish electrical contact therewith without problems of alignment or the like. During joint operation of the laser pointer and the accessory device, the impedance of the variable load varies in response to variations in the predetermined signal characteristic of the electrical input signal. Such variations in the impedance of the variable load automatically modify the flow of electrical current through the laser diode in the laser pointer and thus modulates the intensity of the laser beam in accordance therewith.

摘要： A novel bar code scanner includes a mounting/conveying mechanism that is wearable on or mounted to the body of a user, and/or that is adapted for conveying the scanner from place to place. The bar code scanner also includes a housing, an aperture, an object detection mechanism, a scan data producing mechanism, an optical energy producing mechanism, an optical detector, a bar code symbol detection circuit, a programmed microprocessor, and system control circuitry. Optionally, the aforementioned components may be provided in the form of a two-piece system that includes a scanning engine coupled to a remote unit over a wired or wireless, or wired and wireless, communications link.
