Abstract: An indicia reader comprising: a light source configured for transmitting light onto information bearing indicia (IBI); a light receive circuit comprising a photodetector for converting light reflected from an IBI into photodetector output signals representative of the IBI; a trigger actuated by an operator for activating the indicia reader; a speaker for broadcasting audible voice messages; at least one processor for: decoding IBI information derived from photodetector output signals; controlling the light source and light receive circuit; determining if reader performance is suboptimal and the cause for the suboptimal performance; sending a message to the speaker broadcast the message to notify the operator the cause for the suboptimal performance; and, a housing configured for hand held operation for supporting the light source, light receive circuit, processor, trigger and speaker.

Abstract: 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.

Abstract: The present invention relates to an apparatus packaging components of an optical reading device which may include illumination optical elements, receive optical elements, and signal processing elements. In one embodiment a single circuit board can carry multiple elements such as an image sensor together with illumination elements. In one embodiment, a control circuit can be provided that is coupled to a light source and an image sensor.

Abstract: An optical reader can include an image sensor. In one embodiment an optical reader can be configured to have different operating modes, the different operating modes optimizing the reader for reading different indicia. In another embodiment an optical reader can comprise a multiple color emitting light source. In another embodiment an optical reader can be provided in a specialized form factor including an enlarged head portion and an elongated body portion extending from the head portion.

Abstract: A transaction terminal (10) having a touch screen (20) disposed in a recess (30) in the terminal housing (12) includes an adaptor (25) for facilitating use of the touch screen by persons that are vision-impaired, hearing-impaired or dexterity-challenged. The adaptor (25) is selectively positionable in operative engagement with the touch screen (20). The adaptor (25) includes an insert (50) and a keypad (60, 160, 260). The insert (50) is supported on terminal housing (12) with deck (52) disposed over and in spaced relationship to the touch screen. The deck (52) has at least one discrete opening therethrough. The keypad includes at least one key juxtaposed relative to said least one discrete opening in said deck of the insert. Upon depression of the key, contact is made with a selected portion of the touch screen (20).

Abstract: A point of sale transaction terminal that has a signature capture pad mounted within a platen that is recessed within the top surface of the terminal housing. A screen protector is mounted over the signature pad and is registered thereon so that the protector covers the signature pad. A bezel is mounted upon said platen within the recess of the housing so that the bezel surrounds the periphery of the protector and the capture pad. A latching mechanism is located beneath the bezel which serves to removably secure the bezel to the platen. An access port is provided in said housing that allows restricted access to the latching mechanism for unlatching the bezel.

Abstract: The present invention is a bar code verification device 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.

Abstract: The invention is a transaction terminal having an encryption mode apparatus comprising a secure information entry circuit and a secure mode indicator. The secure information entry circuit is operable to execute an encryption routine including steps that involve application of an encryption algorithm. Further included in the secure mode information entry circuit is cryptographic firmware which adapts the secure information entry circuit so that an encryption mode signal is caused to change state when an encryption routine is called. The indicator of the encryption mode apparatus is made responsive to the encryption mode signal so that the indicator indicates to a user as to whether data entered into the terminal will be encrypted by the terminal.

Abstract: According to the invention, a multilayered image sensor is back mounted to a plate, and the plate in turn, is installed in a holding pocket of a device. In that the scheme takes advantage of a high controllability of a mounting plate's thickness, the mounting scheme provides a tight control of holding forces with which an image sensor is secured in an imaging device. In that the scheme provides for back mounting of image sensor on a planar surface, the mounting system provides tight control of an imaging assembly's pixel plane to fixed point in space distance.
