A device for processing image data relating to bar codes is described. In one embodiment a bar code verification device is provided having an ergonomic form factor characterized by a domed hand held trigger and a viewing window. The verification device may be disposed in a network that includes a host processor system and other bar code reading devices which may include other bar code verification devices. Processing circuitry for processing image signals corresponding to printed bar codes may be partially disposed within the hand held verification device and partially disposed within a host processor system spaced apart from and associated with the hand held verification device. The hand held verification device may be in wireless communication with the host processor system to which it is associated. The bar code verification system may include signal enhancement modules which interpolate constructed pixel values from actual pixel values and which correct for signal degradation resulting from high frequency spatial sampling.

Device and system for processing image data representing bar codes

An optical reader, which is operable in a 'host commands' mode and a 'host routines' mode. In the &#x201c;host commands&#x201d; mode, the reader receives and executes a script routine module from a host. In the &#x201c;host routines&#x201d; mode, the reader receives a script routine Module identifier from the host, and the reader, in turn, executes a selected one of a plurality of reader-stored script routine modules based on the identifier.

Customizable optical reader

A method of operating an indicia reader network comprising the steps of: reading an information bearing indicia of an item with a hand held indicia reader having a first wireless transceiver and generating therefrom an encrypted data message in accordance with a FIPS standard; transmitting the encrypted data message from the indicia reader to a base unit having a second wireless transceiver; decrypting the data message within the base; and transmitting the decrypted data message to a host device, wherein the network is configured so that the indicia reader and the base unit have a linking mode in which a base address of the base unit is sent to the indicia reader, and a reader address is sent to the indicia reader and a request to link is sent to the base unit by way of an encrypted wireless communication between the second wireless transceiver and the first wireless transceiver.

Secure wireless indicia reader

A retail store network comprising a cash register, server, and hand held optical reader for reading a bar code symbol of an item and generating a decoded out bar code data message. The hand held bar code reader has an electrical connector and a wireless transceiver. The optical reader can be used with a base unit also having an electrical connector and a wireless transceiver. The network is configured so that the hand held bar code reader and the base unit have one linking mode in which the address of the base unit is sent to the hand held bar code reader through their respective electrical connectors. The linking process is completed by way of wireless communication, including the transmission of the address of the hand held bar code reader to the base unit. The hand held bar code reader further comprises circuitry to allow the optical reader to also operate in a linking mode where it can link with other devices that it cannot physically mate its electrical connector with, but can initiate the linking and complete the process wirelessly.

Method and system for linking a wireless hand held optical reader with a base unit or other wireless device

An indicia decoding device can have an image sensor and a laser diode assembly configured to project laser light onto a substrate. When a trigger signal is received by the indicia decoding device, the device can calculate a delay and enable the laser diode assembly if a delay threshold is satisfied. The indicia decoding device, in one embodiment, can include a hand held housing and an imaging module carrying the image sensor.

Long range optical reader

Device and system for verifying quality of bar codes

An optical reader in one embodiment can include a substrate defining an opening and solder pads coupled to the substrate proximate the opening. A laser diode including first, second, and third electrical leads can also be coupled to the substrate. First, second and third solder pads can be provided on the substrate and the first, second, and third electrical leads of the laser diode can be coupled to the first, second, and third solder pads. An optical reader in another embodiment can include a substrate having a first surface and a second surface. A laser diode assembly configured to emit a laser beam can be coupled to the first surface and an illumination assembly that can include light emitting diodes can be coupled to the second surface.

A hand held unit is disclosed, the unit including a tracking signal generator and an access authorization signal generator, each signal generator being separately and independently actuatable by a user.
