摘要:
A method of dispensing a product item is disclosed. The product item has packaging. On the packaging are a number of coded data portions. Each coded data portion encodes an identity of the product item and a part of a signature. A sensing device senses one or more coded data portions and generate indicating data indicative of: the identity of the product item; a signature part; and a signature part identifier. A processor receiving the indicating data from the sensing device then determines a determined signature part and authenticates the product item by comparing the received signature part and the determined signature part. Further, a criterion for dispensing the product item is determined and the product item is caused to be dispensed based on the criterion being satisfied.

An image sensing and printing digital camera device includes a housing defining a slot for receiving a printed instruction card having printed thereon an array of dots representing a programming script, the housing further storing therein a roll of print media; an area image sensor for sensing an image and generating pixel data representing the image; a linear image sensor for scanning the array of dots on the card and converting the array of dots into a data signal; a microcontroller provided in the housing, the microcontroller for decoding the data signal into the programming script and applying the programming script on the pixel data; and a printing mechanism for printing the pixel data, having applied thereto the programming script, on the roll of print media. The microcontroller integrates on a single chip a VLIW processor, a printhead interface, and an output buffer effecting communication between the VLIW processor and the printhead interface
摘要:
A process for decoding coded data is provided. The coded data has a plurality of layouts which each have order n (at least two) rotational symmetry and encode a codeword of a sequence of n symbols distributed at n locations about a center of rotational symmetry of the respective layout such that decoding the symbols at each of the n orientations of the layout produces n representations of the codeword. Each representation is a different cyclic shift of the codeword and is indicative of the degree of rotation of the layout. The process involves, at the computer system, identifying a layout from an image including the coded data, decoding the identified layout to determine a codeword representation, and determining a degree of rotation of the layout from the determined representation.

A system is provided having a sensing device for sensing data encoded by a plurality of marks at predetermined positions within a region. The data encoded by each mark is indicative of a functional attribute of that mark's predetermined position. The sensing device is configured to transmit, to a computer system, the sensed data such that the computer system causes execution of a function related to the functional attribute of the sensed data.

A sensing device is provided with an image sensor for capturing images of coded data disposed on a surface, a framestore for storing frames of the captured image as image data, subsampling means for subsampling the stored image date to generate subsampled image data, and an image processor for processing the subsampled image data to generate interaction data based on the sensed coded data and indicative of interaction of the sensing device with the surface. The image processor is integrated on a monolithic integrated circuit, the monolithic integrated circuit including a first subsampled framestore for storing the subsampled image data based on image data from the framestore.

An electronic pen having a retractable nib for interacting with a surface. The pen comprises a slidably movable cartridge having a nib for contacting the surface, a retraction mechanism for retracting the cartridge, an actuator coupled to the retraction mechanism, a force sensor providing a reaction to an axial force transmitted from the cartridge, and a processor configured for generating force data indicative of a force detected by the force sensor. The retraction mechanism comprises a barrel for receiving the cartridge, which is adapted for seating the cartridge in either an extended position or a retracted position, whereby the axial force from the cartridge is transmitted to the barrel in the extended position. A biasing mechanism biases the cartridge towards the extended or retracted positions.

A method of searching a database containing documents with handwritten annotations stored in association with document content is disclosed. The method receives as inputs a handwritten annotation as a handwritten search input and a content element as a content search input. A search is then performed of the database for handwritten annotations in a document matching the handwritten search input and less than a given physical distance from document content equal to the content search input in the document.

A test module for performing a genetic diagnostic assay, the test module having an outer casing dimensioned for hand-held portability, the outer casing having a receptacle for a biological sample containing target nucleic acid sequences, an array of chambers containing probes for hybridization with the target nucleic acid sequences to form probe-target hybrids, a flow-path extending from the inlet to the probes, and, a reagent reservoir containing a reagent for addition to the sample in the flow-path upstream of the probes, wherein, each of the chambers contains less than 270 picograms of probe and the reagent reservoir has a volume less than 1000,000,000 cubic microns.
摘要:
A handheld inkjet printer is disclosed. The printer has a housing, a printhead fixedly mounted in the housing, and a capping device mounted external to the housing. The capping device has an arm, a capping leg extending transversely from the arm and an elastomeric pad affixed to the capping leg and in capping engagement with the printhead. The arm has a resilient portion deformable towards the housing upon receipt of a force. The housing defines a fulcrum with the arm and the leg being positioned on opposite sides of the fulcrum. Deformation of the arm towards the housing causes displacement of the capping leg, which in turn causes the elastomeric pad to move out of capping engagement with the printhead.

A method of displaying hyperlinked information using a handheld display device. The method includes the steps of: imaging an area of a printed substrate and generating image data using an image sensor; determining interaction data using the image data; retrieving display data using an identified page description, the display data including a hyperlink associated with the printed content; displaying, on an opaque touch-sensitive display screen of the handheld display device, display information based on the display data and including the hyperlink; interacting with the displayed hyperlink; retrieving hyperlinked information; and displaying the hyperlinked information. The opaque touch-sensitive display screen has real-time virtual transparency through the screen to the printed content from a user's perspective to provide a virtual window to the printed content.
