Abstract:
Apparatuses and methods for scanned beam imagers and scanned beam endoscopes having a positionable light collector are disclosed. In one aspect, a scanned beam imager includes a scanned beam source operable to scan a beam across a FOV and a light collector structured to collect light affected by the FOV. The light collector is positionable relative to the beam scanned by the scanned beam source. Scanned beam endoscopes and methods of performing endoscopy are also disclosed that implement the above teachings.
Abstract:
A portable end device, such as a bar code scanner, may be equipped with auxiliary interfaces. The auxiliary interfaces may be easily added to the end device as a replaceable cover, such as a replaceable battery door. A signal path conducts signals to and from the replaceable cover. One auxiliary interface is a Bluetooth radio. Data integrity protocols may be selected to guarantee delivery and guarantee no duplicate deliveries. Host pairing algorithms may provide standard or strong pairing with a host computer. Ergonomic interface features allow a user to control and monitor the operation of the end device and the data link with minimal hardware cost and battery life impact. Host software programs provide data routing, automatic reestablishment of the data link, and other functions. The system is adaptable to a wide array of use environments through the selection of timer parameters in the end device.
Abstract:
A system comprising a linerless pressure sensitive label stock and a printer for printing on linerless pressure sensitive label stock exhibit reduced tendency for exposed adhesive to stick to printer components. The linerless pressure sensitive label stock has a plurality of regions that are substantially non-tacky formed along the length of the label stock web. In one embodiment, the non-tacky regions are formed by printing an adhesive deadening agent over the pressure sensitive adhesive. In another embodiment, the adhesive is printed in a pattern having non-tacky regions. Optional perforations in the non-tacky regions aid separation of printed regions from the rest of the web. Various means of web position sensing allow the printer to track the positions of the substantially non-tacky regions. After printing, the web of linerless pressure sensitive label stock is moved to positions where it is unlikely to stick to printer components.

Abstract:
A MEMS scanning device includes more than one type of actuation. In one approach capacitive and magnetic drives combine to move a portion of the device along a common path. In one such structure, the capacitive drive comes from interleaved combs. In another approach, a comb drive combines with a pair of planar electrodes to produce rotation of a central body relative to a substrate. In an optical scanning application, the central body is a mirror. In a biaxial structure, a gimbal ring carries the central body. The gimbal ring may be driven by more than one type of actuation to produce motion about an axis orthogonal to that of the central body. In another aspect, a MEMS scanning device is constructed with a reduced footprint.
Abstract:
A radio replacement using RFID technology in an RF-enabled device is provided. The RF-enabled handheld, portable, or otherwise mobile device is equipped with an RFID tag having read and write capability. Data exchange occurs between the RFID tag and a network of RFID interrogators placed to provide adequate coverage of the area over which the device might move. As a result of replacing a full functioning transmitting/receiving radio with an RFID tag, the cost of the RF-enabled device could be significantly reduced, its battery life could be extended, and it could operate in a frequency band that does not require FCC approval. Additionally, this invention could provide tracking and access control using the RFID tag and interrogators.
Abstract:
A system for storing and retrieving data comprises a memory device, such as a radio frequency tag, having a memory for storing the data, a first identifier stored in the memory, and a machine-readable symbol associated with the memory device. At least a portion of the machine-readable symbol encodes a second identifier logically associable with the first identifier. The machine-readable symbol may be printed on an RF tag, or may be carried by a container that also carries an RF tag. The machine-readable symbol is composed of characters from a machine-readable symbology, and includes a flag character that indicates the existence of a memory device corresponding to the machine-readable symbol. A reader for reading the machine-readable symbol and the memory device conserves power by determining from the flag character whether a memory device is associated with the symbol, prior to operating a memory device reader section of the reader. The reader reads the machine-readable symbol to obtain a symbol identifier, and successively reads each of a number of memory devices to obtain a memory device identifier until a memory device identifier corresponding to the symbol identifier is found. Alternatively, the reader may successively read each of the number of memory devices to obtain each of the memory device identifiers, read the machine-readable symbol to obtain a symbol identifier, and match the symbol identifier to one of the memory device identifiers.
Abstract:
A data carrier reader is capable of executing a number of different reading methods. A method for reading single RFID tags can store read data to a buffer for eventual transmission to a host, and can suppress redundant data. Still another method associates data read from an RFID tag with a particular object or item using a data coded in a machine-readable symbol. In a further method, the machine-readable symbol is automatically read when the RFID tag is within a predetermined proximity of the reader. In each method, the data carrier reader provides the user a consistent and intuitive output to identify the successful and unsuccessful operations such as reading an RFID tag or machine-readable symbol.
