May 14, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Toa, Xi (Suzhou, CN); Liu, Yong (Suzhou, CN); Smith, Taylor (Charlotte, NC); Wang, Ynjiun Paul (Cupertino, CA), filed on October 24, 2013, was made available online on May 1, 2014.

The patent's assignee is Honeywell International Inc.

News editors obtained the following quote from the background information supplied by the inventors: "Indicia reading terminals fir reading decodable indicia are available in multiple varieties. For example, minimally featured indicia reading terminals devoid of a keyboard and display are common in point of sale applications. Indicia reading terminals devoid of a keyboard and display are available in the recognizable gun style form factor having a handle and trigger button (trigger) that can be actuated by an index finger. Indicia reading terminals having, keyboards and displays are also available. Keyboard and display equipped indicia reading terminals are commonly used in shipping and warehouse applications, and are available in form factors incorporating a display and keyboard. In a keyboard and display equipped indicia reading terminal, a trigger button for actuating the output of decoded messages is typically provided in such locations as to enable actuation by a thumb of an operator. Indicia reading terminals in a form devoid of a keyboard and display or in a keyboard and display equipped form are commonly used in a variety of data collection applications including point of sale applications, shipping applications, warehousing applications, security check point applications, and patient care applications, and personal use, common where keyboard and display equipped indicia reading terminal is provided by a personal mobile telephone having indicia reading functionality. Some indicia reading terminals are adapted to read bar code symbols including one or more of one dimensional (1D) bar codes, stacked 1D bar codes, and two dimensional (2D) bar codes. Other indicia reading terminals are adapted to read OCR characters while still other indicia reading terminals are equipped to read both bar code symbols and OCR characters.

BRIEF DESCRIPTION OF THE DRAWINGS

"The features described herein can be better understood pith reference to the drawings described below. The drawings are not necessarily to scale, emphasis instead generally being placed upon illustrating the principles of the invention. In the drawings, like numerals are used to indicate like parts throughout the various views.

"FIG. 1 is a block diagram of an apparatus for use in decoding a bar code symbol, the apparatus having an image sensor and LED dies mounted directly on a single printed circuit board, in accordance with an aspect of the invention;

"FIG. 2 is a block diagram of an apparatus for use in decoding a bar code symbol, the apparatus having an image sensor, LED dies, and LED drive circuitry mounted directly on a single printed circuit board, in accordance with an aspect of the invention;

"FIG. 3 is a block diagram of an apparatus for use in decoding a bar code symbol, the apparatus having an image sensor, LED dies, LED drive circuitry, and processor circuitry mounted directly on a single printed circuit board, in accordance with an aspect of the invention;

"FIG. 4 is an exploded perspective view of an apparatus for use in decoding a bar code symbol, in accordance with an aspect of the invention;

"FIG. 5 is a block diagram of an apparatus for use in decoding a bar code symbol, the apparatus having multiple elements mounted directly on a single printed circuit board in accordance with an aspect of the invention; and

"FIG. 6 is a perspective view of an apparatus for use in decoding a bar code symbol, in accordance with an aspect of the invention,"

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "According to one aspect an invention for use in decoding a bar code symbol is provided. The apparatus may include an image sensor integrated circuit having a plurality of pixels arranged in a plurality of rows and columns of pixels, timing and control circuitry for controlling an image sensor, gain circuitry for controlling the gain of one or more signals, analog to digital conversion circuitry for conversion of an analog signal to a digital signal, and a plurality of electrode pads on a surface of the image sensor integrated circuit. The apparatus may also include a light source bank. Further, the apparatus may include a single printed circuit board for receiving the image sensor integrated circuit and the light source bank and including a plurality of contact pads disposed on a surface of the printed circuit board. The image sensor integrated circuit may be mounted directly on the single printed circuit board and then wire bonded directly to the printed circuit board to provide electrical input/output and mechanical connections between the image sensor integrated circuit and the printed circuit board. The light source bank may be mounted directly on the single printed circuit board and then wire bonded directly to the printed circuit board to provide electrical input/output and mechanical connections between the light source bank and the printed circuit board. The apparatus may be operative for processing image signals generated by the image sensor integrated circuit for attempting to decode the bar code symbol.

"According to alternative aspects, the apparatus may further comprise a hand held housing encapsulating the image sensor integrated circuit and the light source hank. In one aspect, the light source bank may be an LED die. In a further aspect, light source bank circuitry may be mounted directly to the single printed circuit board and wire bonded directly to the printed circuit board. In another aspect, a processor circuitry may be mounted directly to the single printed circuit board and wire bonded directly to the printed circuit board. In another aspect, the apparatus may include an aimer light source bank positioned on the printed circuit board. The aimer light source bank may be an LED die. The apparatus may include an aimer subsystem electrically connected to the printed circuit board. In another aspect, the processing of image signals generated by the image sensor integrated circuit for attempting to decode the bar code symbol may be performed within the housing. In another aspect, the processing of the image signal generated by the image sensor integrated circuit for attempting to decode the bar code symbol is performed by circuitry external to the housing. In another aspect, the processing of image signals generated by the image sensor integrated circuit for attempting to decode the bar code symbol may be performed by a circuit disposed on the primed circuit board. In an alternative aspect, the processing of image signals generated by the image sensor integrated circuit for attempting to decode the bar code symbol may be performed by a computer external to the housing."
