Abstract

A portable data collection device (10) adapted to be mounted to a shopping cart (18) is disclosed. The device includes a housing (12) having a clamping assembly (80, 82, 84, and 86) for releasably clamping the housing to a pushing bar (16) of a shopping cart (18). The housing (12) defines an interior region supporting device electronics. The device further includes an interactive touch sensitive visual display screen (110, 112) and a retractable, tethered dataform reader (22) releasable mounted on the housing (12). When mounted on the housing (12), an imaging assembly (42) and an illumination assembly (44) of the reader (22) are continuously actuated to read a dataform presented to the reader. When removed from the housing, (12) the reader (22) is actuated by depressing a trigger (40) on the reader. The device also includes a magnetic stripe reading assembly (60), a printer (62) and communications circuitry (118) including a radio communicator module. A locator provides position information of the portable collection device (10) relative to a distribution facility via data interchange with a plurality of transceivers (166, 168). Information selectively obtained from the transceivers (166, 168) allows for selective retrieval and display of information on the visual display screen (110, 112) which is keyed to product type or location of the portable collection device (110).

Claims

1. A distribution facility product data information display system comprising:

a base unit including

base communicator means adapted for interchange of remote data with at least one associated portable data terminal, the remote data including at least one of query data and product data,

means for receiving position data representative of a relative position of the at least one associated portable data terminal relative to an associated product distribution facility, and

base processor means, including data storage, for generating response data in response to at least one of query data and position data; and

each associated portable data terminal, including

remote communicator means adapted for remote data interchange with at least the base unit,

remote processor means for communicating query data to the base unit, and

user interface adapted for selectively receiving data.

2. The consumer product data information display system of claim 1 further including a means for selectively generating query data in accordance with indicia disposed on an associated product.

3. The consumer product data information display system of claim 1 further comprising means for generating the position data in accordance with at least one of transponder data communicated from each of the at least one associated portable data terminal, and coordinate data associated with a plurality of spatially separated access points.

4. The consumer product data information display system of claim 2 wherein the means for selectively generating query data includes a bar code reader.

5. The consumer product data information display system of claim 2 wherein the means for selectively generating query data includes a touch panel.

6. The consumer product data information display system of claim 2 wherein the means for receiving position data includes a plurality of transducers disposed throughout the distribution facility, each transducer being selectively placed in data communication with each associated portable data terminal in accordance with a relative proximity therebetween.

7. The consumer product data information display system of claim 6 wherein the product data is comprised of hypertext mark-up language, and wherein in the user interface includes a graphical video display terminal adapted for selectively displaying a graphical representation of the product data via a web browser application.

8. The consumer product data information display system of claim 6 further comprising means for fixedly securing the at least one associated portable data terminal to an associated shopping cart.

9. A method of consumer product data information display comprising the steps of:

selectively receiving queries into at least one portable data terminal;

generating position data representative of a relative position of the at least one portable data terminal relative to a distribution facility;

receiving queries, into a base unit, from the at least one portable data terminal;

selectively accessing product data from a data storage in accordance with at least one of received query data and position data;

communicating product data accessed as a result of received query data from the base unit to the at least one portable data terminal associated with such query data; and

selectively displaying product data on a video display of the at least one portable data terminal.

10. The method of consumer product data information display of claim 9, further comprising the step of selectively forming queries in accordance with product indicia.

11. The method of consumer product data information display of claim 10 wherein the step of selectively forming queries includes the step of accessing product indicia via at least one of a bar code reader and a touch panel.
