A system and process for broadcast and communication with bi-level or sketch video at extremely low bandwidths is described. Essentially, bi-level and sketch video presents the outlines of the objects in a scene being depicted. Bi-level and sketch video provides a clearer shape, smoother motion, shorter initial latency and cheaper computational cost than do conventional DCT-based video compression methods. This is accomplished by converting each color or gray-scale image frame to bi-level or sketch image frame using adaptive thresholding method, compressing bi-level or sketch image frames into bi-level or sketch video using adaptive context-based arithmetic coding method. Bi-level or sketch video is particularly suitable to such small devices as Pocket PCs and mobile phones that possess small display screen, low bandwidth connection, and light computational power.

A relocatable container inspection device, which is constituted by modularized units, is used for inspecting a container. The device comprises: a first cabin unit including a radiation source for generating a beam of penetration radiation for penetrating the container to be inspected; a second cabin unit including detectors for detecting the beam of penetration radiation penetrating through the container being inspected and producing corresponding radiographic signals, the second cabin unit and the first cabin unit being arranged oppositely in both sides of an inspection passage; a gantry unit bridging the first cabin unit and the second cabin unit to form a portal-shaped frame adapted for straddling the container being inspected; means for moving the frame relative to the container being inspected along the inspection passage, so that the detectors receive the beam of the penetration radiation generated from the radiation resource and passing through the container being inspected, thereby continuously scanning the container and producing the corresponding radiographic signals, wherein the first cabin unit, the second cabin unit and the gantry unit are all individually made as modular units so as to be quickly and easily assembled and disassembled with each other on the inspection site. In the present invention, all of the modularized units of the container inspection device can be easily assembled and disassembled in the work field, and the dimensions of each modular unit are sized to be suitable for road transports and to be facilitate for the device's movement.

A hardcopy printing mechanism and a greeting card feeder retrofit kit therefor, along with a retrofitting method are provided for printing images on a first-sized media, and on both surfaces a second-sized greeting card media without removing the first-sized media from its normal supply tray. The hardcopy device may be an electrophotographic or inkjet printer preferably equipped with a duplexer module which inverts media from a printed first surface to an opposing second surface for printing an image thereon. For a printer having an alignment surface, and a width adjuster to push the first-sized media against the alignment surface, the greeting card feeder includes a biasing member which pushes the card stock against the alignment surface. The retrofit kit includes a supply of pre-scored greeting card stock and a software program with a group of greeting card images for a consumer to select from to print store-bought quality greeting cards.

Devices, systems, and methods for treating and / or determining appropriate prescriptions for one or both eyes of a patient are particularly well-suited for addressing presbyopia, often in combination with concurrent treatments of other vision defects. High-order spherical aberration may be imposed in one or both of a patient's eyes, often as a controlled amount of negative spherical aberration extending across a pupil. A desired presbyopia-mitigating quantity of high-order spherical aberration may be defined by one or more spherical Zernike coefficients, which may be combined with Zernike coefficients generated from a wavefront aberrometer. The resulting prescription can be imposed using refractive surgical techniques such as laser eye surgery, using intraocular lenses and other implanted structures, using contact lenses, using temporary or permanent corneal reshaping techniques, and / or the like.

The present invention provides a driving method of a display device for expressing gray scales with n bits (n is an integer) by dividing one frame into a plurality of subframes. By this driving method, pseudo contours which occur in displaying images by a time gray scale method can be reduced.

The invention provides information to the potential customer about the vehicle for sale, including information relating to other similar vehicles for sale in a particular geographical area that can be accessed at the point of sale, or by the customer at a later time and place. The party offering the product for sale is informed each time the customer accesses the information, thereby indicating the level of interest by the customer.

A liquid crystal display device for displaying video data having a detection circuit for detecting a luminance distribution based on video data which is inputted, the luminance distribution being indicative of generation frequency of gradations in each of divided region which includes a plurality of gradations. The display device includes a determination circuit for determining at least one of a plurality of divided regions of higher generation frequency of gradation than that of other divided regions based on the luminance distribution, a correction circuit for correcting the video data so as to make a luminance characteristic of the at least one of the plurality of divided regions of higher generation frequency of gradation more abrupt than a luminance characteristic of the other divided regions, and a liquid crystal display panel for displaying the corrected video data. A width of the divided region is changeable.

A plasma display panel (PDP) includes a frameless EMI filter supported by a glass substrate for blocking / shielding substantial amounts of electromagnetic waves, with the filter being supported by a side of the substrate opposite a viewer. In certain example embodiments, the PDP filter includes a transparent conductive coating (TCC) for electromagnetic interference (EMI) and near infrared (NIR) blocking without the need for a conductive, peripheral buss bar. Additionally, in certain example embodiments, the need for a conductive frame is reduced or eliminated. The filter has high visible transmission, and is capable of blocking / shielding electromagnetic waves.

An electrode inspection apparatus for spot welding is provided for precisely measuring diameters of a tip of an electrode without reducing availability ratio in a production line, and is particularly useful when inspecting a weld gun having electrodes with a narrow distance therebetween.A CCD camera 91 for imaging the tip of the electrode held to the weld gun is disposed in an inspection apparatus body 6.

The CCD camera 91 is disposed in a side of the mirror 8 with a distance therebetween for imaging the tip of the electrode from a direct front thereof reflected on the mirror 8 by reflection.

The invention includes a method and system to provide a competitive pricing tool so that automobile dealers can more efficiently and effectively price their used vehicles. The system achieves the optimal sales price by obtaining the relevant pricing and mileage of vehicles for sale that are similarly situated to the focus vehicle. Once the information is obtained, the system creates a value ranking for each of the vehicles for sale and for the focus vehicle. The user is then able to revise the focus vehicle pricing to determine the optimal sales price.

A dental instrument and method for imaging the three-dimensional topography of one or more teeth in the oral cavity of an individual is provided. The instrument includes a probe insertable into the oral cavity to receive the image of these surfaces which can then be processed. Combined with the probe is an auxiliary which projects an air stream toward the surface to be imaged by the probe and acts to evaporate and remove from these surfaces a liquid film coating formed by saliva and other fluids present in the oral cavity, to render these surfaces dry and enhance their reflectivity and in doing so, provide clearer images.
