Automatic data collection devices such as barcode readers, RFID readers, magnetic stripe readers and the like may be tested using ADC device test executables, modules or processes stored at a variety of network locations. One or more sets of tests or work lists may be defined to facilitate testing. Tests may be identified by name and / or keyword. Keywords may be indicative one or more functionalities tested by the respective ADC device test module.

Methods, systems, and apparatuses for a reader transceiver circuit are described. The reader transceiver circuit incorporates a frequency generator, such as a surface acoustic wave (SAW) oscillator. A reader incorporating the reader transceiver circuit is configured to read a tag at very close range, including while being in contact with the tag. The transceiver can be coupled to various host devices in a variety of ways, including being located in a RFID reader (e.g., mobile or fixed position), a computing device, a barcode reader, etc. The transceiver can be located in an RFID module that is attachable to a host device, can be configured in the host device, or can be configured to communicate with the host device over a distance. The RFID module may include one or more antennas, such as a first antenna configured to receive a magnetic field component of an electromagnetic wave and a second antenna configured to receive an electric field component of an electromagnetic wave. The RFID module may include a detector that is configured to determine if the RFID module is positioned in proximity to an object, such as a RFID tag. The detector may operate as a trigger for the RFID module, to enable or trigger a function of the RFID module.

A barcode-embedding area is obtained in a color image based on expression possibility by the juxtaposed additive color mixture and possibility of reading of pixels separately by a barcode reader (S11), a color image in the barcode-embedding area is expressed by the juxtaposed additive color mixture, and color images for the code area and the background area, which are readable by the barcode reader, are created (S12, S13), a color-image-superimposed barcode image is created by using the color images for the code area and the background area, and the same color-image-superimposed barcode image is embedded in the barcode-embedding area (S14), and the color-image-superimposed barcode image and the original color image are corrected if necessary (S15, S16).

Barcode scanning and digitizing technology incorporated in the tip of a white cane for the blind, which houses barcode reader, sonar, color sensory and audio production mechanisms. Apparatus detects and announces via audio or vibratory output, obstacles, drop-offs, colors or suitable informational barcode sites placed with a plurality of locations or environments for assisting blind or visually impaired users to navigate. In one embodiment, the apparatus combines the white cane with a barcode scanner and decoder with laser depth finding capacity in the cane tip, an sonar technology within the cane housing; and a separate hand-held unit having color and standard UPC barcode scanners, both the cane and the hand-held unit being connected to the audio output device by a hard-wire or wireless connection. The audio production unit can be pocket or purse carried and emits verbal information via respective barcodes suitable for either component or announces color when the respective scanner is used; hand-held color / barcode scanner or cane can be used separately or simultaneously.

A printed barcode including first basic barcode information stored in a first basic mode of printed data storage, and second additional enhanced barcode information stored in a second enhanced mode of printed data storage. The second information is printed, at least partially, as a component of the first information. The first information is adapted to be read by a basic barcode reader. The second information is adapted to be read by an enhanced barcode reader and cannot be read by the basic barcode reader.

Apparatus for reading RFID tags of picked goods as they are loaded onto a picked pallet, and a method of picking and tracking goods using the device. The invention is mounted on a pallet support on a pallet conveyance, and has an RFID interrogator connected to at least one antenna mounted on a vertically movable antenna mount. The interrogator triggers the transponders in the goods and sends the decoded replies to the control unit. An object sensor adjacent to the antenna senses the presence of goods, and a control unit controls the movable antenna mount to raise the antenna mount above the goods. A computer having a display visible to an operator loading the pallet conveyance is used to communicate with the operator, confirming the loaded goods are the correct ones, and tracking inventory loaded on the conveyance. A barcode reader may be located on the antenna mount.

A thrombectomy catheter deployment system which greatly simplifies setup procedures and operation of a thrombectomy catheter includes a stand alone drive unit and a disposable pump / catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump / catheter assembly has a plurality of preconnected components including tubular structure and a thrombectomy catheter connected thereto and is transported into or out of the interior of the drive unit for automatic high pressure pump piston head engagement or disengagement with a reciprocating linear actuator and for automatic engagement or disengagement of an effluent waste tube with a roller pump. A barcode reader senses specific operational data pertaining to an individual pump and provides an interface for operation of the reciprocating linear actuator. A bubble trap incorporated for effective debubbling of saline solution is closely coupled to an insert molded pump having an improved valve arrangement. A spiked bag with large tubing is incorporated for bubble-free transfer of saline.
