Abstract: Disclosed are sweetened consumables and methods of forming said sweetened consumables that comprise certain sweeteners and a compound of formula (1), wherein R1 is selected from the group consisting of OH and OCH3, and R2 is selected from the group consisting of H and OH, R1 and R2 comprise at least one OH group, and when R1 is OH then R2 is H (trilobatin), and when R1 is OCH3 then R2 is OH (HDG), in a concentration near its sweetness detection threshold. The sweeteners include sucrose, fructose, glucose, high fructose corn syrup, corn syrup, xylose, arabinose, rhamnose, erythritol, xylitol, mannitol, sorbitol, inositol, acesulfame potassium, aspartame, neotame, sucralose, saccharine, or combinations thereof.

Abstract: A head mounted display can include a frame, an eyepiece, an image injection device, a sensor array, a reflector, and an off-axis optical element. The frame can be configured to be supported on the head of the user. The eyepiece can be coupled to the frame and configured to be disposed in front of an eye of the user. The eyepiece can include a plurality of layers. The image injection device can be configured to provide image content to the eyepiece for viewing by the user. The sensor array can be integrated in or one the eyepiece. The reflector can be disposed in or on the eyepiece and configured to reflect light received from an object for imaging by the sensor array. The off-axis optical element can be disposed in or one the eyepiece. The off-axis optical element can be configured to receive light reflected from the reflector and direct at least a portion of the light toward the sensor array.

Abstract: According to examples, an apparatus may include a processor and a memory on which is stored machine readable instructions executable by the processor to detect edges of a scanned object image. The instructions may also cause the processor to determine, based on the detected edges, that a feed skew has occurred on the scanned object image. In addition, based on a determination that the feed skew has occurred, the instructions may cause the processor to identify curved edges of the scanned object image, de-curve the identified curved edges through horizontal scanline scaling of the scanned object image to form a de-curved image, and produce a corrected image through vertical scanline scaling of the de-curved image.

Abstract: A technique includes acquiring data representing a first image produced by electronically scanning a page against a background. The first image contains a non-uniform background content due at least in part to a variation introduced by the background being non-uniform. The technique includes extracting an image of the page from the first image, wherein the extraction includes characterizing the background content of the first image; identifying candidate pixels associated with the page based at least in part on the characterized background content; and based at least in part on the identified candidate pixels and a model for a boundary of the page, determining the boundary of the page.

Abstract: Recognizing a command may include monitoring a tangible reference with a depth sensor, maintaining a virtual reference approximately on calibrated three dimensional coordinates of the tangible reference, maintaining a touch space adjacent the virtual reference, and recognizing a command when a predetermined object enters the touch space.

Abstract: A method for implementing gesture based human interfaces includes segmenting data generated by an IR camera of an active area and detecting objects in an active area. The objects are distinguished as either island objects or peninsula objects and a human hand is identified from among the peninsula objects. The motion of the human hand is tracked as a function of time and a gesture made by the human hand is recognized.

Abstract: A scanning device of one embodiment of the invention is disclosed that includes a scanning mechanism and a removable storage media mechanism disposed within a housing of the scanning device. The scanning mechanism is to scan image data from scannable media. The removable storage media mechanism is receptive to a removable storage medium on which the image data scanned from the scannable media is stored.

Abstract: A system and method for removing optical iridescent artifacts in an image includes scanning an article having a transparent and reflective surface to create the image, identifying potential optical iridescent artifacts in the image resulting from the scan using a search pattern on the image of the article, confirming through a color analysis operation that the potential optical iridescent artifacts discovered along the search pattern are optical iridescent artifacts and not printed on the article and removing the confirmed iridescent artifacts from the image.

Abstract: A method of inhibiting printing of counterfeit legal tender is such as to analyze acquired digital image data to detect a presence of data indicative of predetermined fibers in an image represented by the image data. This method further includes one of modifying or preventing printing of a image in accordance with an outcome of the analysis of the image data.

Abstract: A method of processing a color digital image file provides a “metallic,” or a “sepia,” or an “antiqued” image file. The resulting image files may be viewed, for example, on a computer monitor, or may be printed out in hard copy form using a black-and-white or color printer. A color photocopy machine which has a digital image output may be used to produce the original image file, and such a color photocopier (if it will accept digital image files), may also be used to produce the output hard copy printouts of processed image files. Thus, such a digital photocopier may be configured internally to also process image files, and may be employed to selectively process images copied on the machine into the user's choice of a metallic, a sepia, or an antiqued image on the output hardcopy of the color photocopier.
