摘要:
A computer method of creating a super-resolved grayscale image from lower-resolution images using an L1 norm data fidelity penalty term to enforce similarities between low and a high-resolution image estimates is provided. A spatial penalty term encourages sharp edges in the high-resolution image, the data fidelity penalty term is applied to space invariant point spread function, translational, affine, projective and dense motion models including fusing the lower-resolution images, to estimate a blurred higher-resolution image and then a deblurred image. The data fidelity penalty term uses the L1 norm in a likelihood fidelity term for motion estimation errors. The spatial penalty term uses bilateral-TV regularization with an image having horizontal and vertical pixel-shift terms, and a scalar weight between 0 and 1. The penalty terms create an overall cost function having steepest descent optimization applied for minimization. Direct image operator effects replace matrices for speed and efficiency.

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.

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.

An optical reader, which is operable in a “host commands” mode and a “host routines” mode. In the “host commands” mode, the reader receives and executes a script routine module from a host. In the “host routines” 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.

A system for converting a collection of data to a structured, printable and navigable document includes: an analyzer and a layout unit. The analyzer is coupled to receive a data collection source such as a web page associated with a wiki and other user parameters, and generates a representation of content associated with the data collection source. The output of the analyzer is coupled to an input of the layout unit to provide the representation of content. The layout unit is also coupled to receive a style sheet or other user preferences. The linearizer of the layout unit retrieves the necessary content using the representation of content. The retrieved content is then formatted by the layout selector of the layout unit to generate a paginated document and metadata. This output can then be printed on any conventional printer or manipulated and interacted with using applications or a web browser.

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.
摘要:
An easily deployed barrier 400, shade or shield intended for agricultural or horticultural protection against hail, birds, sunlight, and the like is comprised of open-weave fabric 401 held over the items 402 to be protected so that it tends to assume a rectangular outline when in the fully spread out position and tends to become a slanted parallelogram outline when in the fully closed or contracted position. The shape of the barrier is altered by pulling either cord 411 or cord 410 along one edge along the direction of the length of the cloth. Accessories including supports 403, deposited-load release mechanisms 422, cross-cables 412 for stability, and deployment means 415, 419 are also described. The barriers may be deployed automatically. Barriers of this type can cover large areas such as an entire orchard.
摘要:
A frangible clip which gives way at a loading less than the limits of supporting structures is used in bulk to secure panels of porous cloth to supporting cables. The porous cloth is that used in agriculture for shade, wind, rain, hall, or snow protection of plants or animals. The clips are installed to form loops which slide along support cables and which pass through the structure of the cloth and around a preferred soft-sheathed hem cable which strengthens all edges of the cloth. A panel of porous cloth may be held stretched out by anchoring hem cables at a first corner, passed around anchored pulleys at each adjacent corner, and tensioning them onto an anchor at the far corner. The anchors may be attached to the support cables or to poles or ground structures. These improvements are useful in minimising storm damage.
