摘要:
The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. The deposited powder bed is heated to about 50° C. to about 170° C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

Techniques for automatically comparing one or more objects determined from digital media content (e.g., an image, audio information, video information) to one or more objects specified by a machine readable identifier to determine if an object determined from the media content matches an object specified by the machine readable identifier. One or more actions may be initiated upon determining that an object determined from the media content matches an object specified by the machine readable identifier. Information identifying the action to be initiated may also be encapsulated by the machine readable identifier.

The disclosure includes a system and method for distinguishing between items of similar appearance that vary in size. An image recognition application receives an image including a plurality of items, identifies each item in the image, generates a region of interest for each identified item in the image, determines a dimension of the region of interest for each identified item in pixels, determines a plurality of pixel-to-physical dimension ratios for each identified item, identifies a selected pixel-to-physical dimension ratio among the plurality of pixel-to-physical dimension ratios, and determines a stock keeping unit identifier of each identified item in the image based on the selected pixel-to-physical dimension ratio and the dimension of the region of interest for each identified item.

A method for sequencing products on a retail shelf, or other objects, recognized in an image of the retail shelf includes detecting products in the received image and calculating a final sequence position for each detected product. The final sequence position is calculated by generating a region of interest for each detected product in the received image, generating a plurality of unique raster numbers for each region of interest using a raster number equation by varying parameters of the raster number equation based on pixel coordinates of each region of interest, determining a plurality of sequence positions for each region of interest using the plurality of unique raster numbers, and determining the final sequence position for each region of interest using the plurality of sequence positions for each region of interest. The disclosure also includes systems for implementing the method.

A user interface for a portable computing device provides two modes of operation. In a first mode, an inbox of all documents accessible by the portable computing device are presented. Each of the items in the inbox is selectable, and if selected, the user interface transitions to a second document presentation mode. In the document presentation mode, the user may annotate the document and upon providing a single input (selecting a submit button), the system automatically forwards the document (including the annotations) to the next state in the workflow. If the user transitions back to the inbox mode from the document presentation mode, no action is taken on the document but the strokes are stored with the document on the portable computing device.

An image forming apparatus, a process cartridge, and a developing unit includes a developer carrying member to carry developer, first and second rotary members arranged in parallel to each other and configured to rotate to agitate and convey the developer, and an enclosure having an inside space to contain the developer, the inside space being divided by a partition with communication openings formed therein at opposite ends thereof into a first chamber configured to maintain the developer above a first level and to hold the first rotary member therein which supplies the developer to the developer carrying member while agitating and conveying the developer, and a second chamber configured to communicate with the first chamber through the communication openings, to maintain the developer at a second level lower than the first level, and to hold the second rotary member therein which circulates the developer with the first chamber through the communication openings.
摘要:
A smart display detection system is disclosed. The smart display system is configured to allow mobile users to connect with display screens through mobile device cameras. The system can detect the display screens within images captured by the mobile device camera in real time by matching the camera query image with screen images dynamically updated from the display devices. A synchronized time-stamped matching strategy is applied to achieve high performance in detecting the screens playing motion intensive video contents and an aggressive feature selection method is applied to minimize the system uploading bandwidth. The system can accurately find display screens playing either static or dynamic content within an image captured on a mobile device.
摘要:
A system and a method for updating an electronic paper display are disclosed. A memory includes a waveform table and a transition matrix including multiple pixels, each representing a pixel of the electronic paper display. A page transition display system is coupled to the memory and identifies waveforms from the waveform table associated with multiple transition matrix pixels by processing multiple transition matrix pixels in parallel. For example, the page transition display system loads multiple transition matrix pixels into a register and accesses the waveform table using the contents of the register. Using the identified waveforms, the page transition display system generates control signals used to modify the electronic paper device.

Embodiments digitize radiology films into DICOM format. Radiology films typically include an array of captured images laid out in a grid pattern. To comply with DICOM format, the scanned image of a radiology film is segmented into sub-images and text is extracted from the sub-images to generate DICOM metadata. The sub-images and extracted text metadata are then combined to generate a DICOM-compliant multi-image file.
