Abstract

A system for storing, accessing and displaying HTML-encoded documents relating to an object being worked upon in a work environment by a human operator. The human operator wears a body-wearable http-enabled client system equipped with a code symbol reader programmed to read a URL-encoded symbol on the object pointing to a HTML-encoded document stored on one or more http-enabled information servers. The http-enabled client system is connected to the information network by a two-way wireless telecommunication link. The code symbol reader is programmed for reading the URL-encoded symbol affixed to the object and automatically produces symbol character data representative of the read code symbol and the URL encoded therewithin. The http-enabled client system also includes a network accessing mechanism and a display device. The network accessing mechanism is programmed for automatically accessing one or more of the HTML-encoded documents from one or more of the http-enabled information servers in response to symbol character data being produced by the code symbol reader. The display device is operably connected to the network accessing mechanism, for visually displaying HTML-encoded documents accessed from the http-enabled information servers in response to symbol character data being produced by the code symbol reader. As a result of the present invention, the human operator is enabled to freely review the HTML-encoded documents displayed on the display device while working with the object in diverse work environments involving, for example, inventory management, assembly-line and/or plant inspection, and craft or vehicle inspection and/or repair.

Claims

1. A system for storing, accessing and displaying HTML-encoded documents relating to an object being worked upon by a human operator in a work environment, said system comprising:

(1) one or more http-enabled information servers connected to an information network supporting the TCP/IP standard, and storing one or more HTML-encoded documents related to said object being worked upon by said human operator in said work environment, each said HTML-encoded document being stored within one said http-enabled information server at a location specified by a uniform resource locator (URL) encoded within the structure of a code symbol affixed to said object; and

(2) said body-wearable http-enabled client system operably connected to said information network by a two-way wireless telecommunication link, and including

(a) a body-wearable housing mountable to the arm of said human operator,

(b) a code symbol reader, disposed within said body-wearable housing, programmed for reading said code symbol affixed to said object and automatically producing symbol character data representative of said read code symbol and the URL encoded therewithin;

(c) network accessing means programmed for automatically accessing said HTML-encoded documents from one or more of said http-enabled information servers in response to said symbol character data being produced by said code symbol reader; and

(d) display means operably connected to said network accessing means, for visually displaying said one or more HTML-encoded documents accessed by said network accessing means from said one or more http-enabled information servers in response to said symbol character data being produced by said code symbol reader;

whereby said human operator is enabled to review said one or more HTML-encoded documents displayed on said display means while working with said object in said work environment.

2. The system of claim 1, wherein said code symbol reader is a device selected from the group consisting of a laser scanning bar code symbol reader, a CCD bar code symbol reader, and a wand-type bar code symbol reader, and a magnetic-stripe reader.

3. The system of claim 1, which further comprises information entry means, associated with said body-wearable housing, for entering information into said body-wearable http-enabled client system.

4. The system of claim 3, wherein said information entry means comprises a keypad.

5. The system of claim of claim 1, wherein said network accessing means comprises:

computing means for executing computer programs, including an Internet browser program; and

an Internet browser program executable by said computing means and supporting the client-side of the HTTP standard so that said network accessing means can access said HTML-encoded documents from said one or more http-enabled information servers.

6. The system of claim 1, wherein said two-way wireless telecommunication link comprises a first modem operably connected to said body-wearable http-enabled client system and a second modem operably connected to said information network.

7. The system of claim 1, wherein said code symbol reader is an automatic laser scanning bar code symbol reader.

8. The system of claim 1, wherein said display means is a visual display device supportable upon the head of said human operator.
