Abstract:
A system and method for the automatic selection printer operating parameters using a preprinted bar code image on a portion of a selected print medium or a separate sheet of bar code parameters and commands. The bar code image specified characteristics of the selected print medium. A bar code scanner operates in conjunction with a bar code printer and scans the bar code image. The system automatically selects printer operating parameters, such as print speed, print head pressure, and burn duration to configure the printer for optimal operation with the selected print medium. The bar codes can also be used for test and service, label design, data entry, or work in process.
Abstract:
An integrated photonics module may include a selective fold mirror configured to pass at least a portion of emitted light toward the MEMS scanner and reflect scanned light through to a field of view. The selective fold mirror may use beam polarization to select beam passing and reflection. The integrated photonics module may include a beam rotator such as a quarter-wave plate to convert the polarization of the emitted light to a different polarization adapted for passage through the fold mirror. The integrated photonics module may include one or more light detectors.
Abstract:
A method and apparatus for convenient and easy access to product- and shipment-related information and/or transactions is disclosed. A radio frequency tag reader is used to read a radio frequency tag having a structured data format. The end device parses one or more particular data entities from the data read. The radio frequency tag reader accesses a URL having at least a portion in common with one or more of the parsed data entities and displays associated web page content or processes an associated transaction. The radio frequency tag reader may sequentially substitute a series of most probable non-common URL portions to locate associated content if the first tried URL does not result in a valid response. Alternatively, a server may provide such search functionality.

The selective fold mirror may use beam polarization to select beam passing and reflection. The integrated photonics module may include a beam rotator such as a quarter-wave plate to convert the polarization of the emitted light to a different polarization adapted for passage through the fold mirror. The integrated photonics module may include one or more light detectors.
Abstract:
An endoscope system and method includes an endoscope tip coupled to a endoscope console for providing images of anatomical features imaged using the endoscope system. The system also includes a calibration device having known optical properties. The calibration device is imaged using the endoscope system, and data corresponding to the image is obtained. This data are compared to data corresponding to the known optical properties of the calibration device. Based on this comparison, calibration data corresponding to imaging errors of the endoscope system are obtained. The calibration data are used to calibrate the endoscope system.
Abstract:
Methods and apparatuses for selecting and displaying an image with the best focus are disclosed. In one aspect, a method of displaying a captured image includes capturing a plurality of images of a field of view (FOV) using an image capture device, selecting one of the images having the best focus, and displaying the selected image on the image capture device. In another aspect, a method of displaying a captured image includes capturing a plurality of images of a FOV, dividing each of the images into a plurality of regions, and comparing corresponding regions from each of the images. The regions having the best focus are selected. A composite image is constructed formed from the regions with the best focus and the composite image is displayed. Image capture devices configured to effect the above methods are also disclosed.
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.

According to embodiments, scanned beam source may include a first beam shaping optical element aligned to receive a composite beam of light carrying a plurality of wavelength components and a second beam shaping optical element aligned to receive the composite beam of light from the first beam shaping optical element and configured to modify the first plurality of wavelength components of the composite beam to a plurality of dimensions proportional to wavelength. The first beam shaping optic may be, for example, a top-hat converter. The second beam-shaping optic may be, for example, a polarization-sensitive clipping aperture, a wavelength-dependent clipping aperture, and/or an achromatic corrector.
