Methods and systems for the manufacture of layered three-dimensional forms
ActiveUS20050017394A1Lower potentialEasy to controlConfectionerySweetmeatsParticulatesBiological activation
New methods and systems for manufacturing a three-dimensional form, comprising steps of providing a plurality of particulates; contacting the particulates with an activation agent; contacting particulates having the activation agent with a binder material that is activatable by the activation agent; at least partially hardening the binder for forming a layer of the three-dimensional form; and repeating these steps to form the remainder of the three-dimensional form. Following sequential application of all required layers and binder material to make the form, the unbound particles are appropriately removed (and optionally re-used), to result in the desired three-dimensional form. The invention also contemplates a novel method for preparing a form, where unbound particulates free of binder material are re-claimed.

Optical device utilizing optical waveguides and mechanical light-switches
InactiveUS6650822B1High refractive indexReduction factorCoupling light guidesOptical waveguide light guidePhotovoltaic detectorsPhotodetector
An optical device consists of one or more optical waveguides and mechanical light switches 30. When a light switch 30 is turned on, it extracts light beam 62a from a waveguide core 20 and redirect the light beam 62b into free space, it redirects an incoming light beam 80 from free space and injects the light beam 80a into the waveguide core 20, or it performs both functions at the same time, depending on specific applications. On and off states of a light switch 30 are achieved by pulling the light switch 30 into a close vicinity of the waveguide core 20 and by pushing the light switch 30 away from the waveguide core 20, respectively. An interactive fiat-panel display can be built based on this invention. A plurality of parallel channel waveguides forms a display panel. An array of light beams 62a, injected from an array light source 60, propagates along waveguide cores 20 until reaches a location where a light switch 30 is turned on. At this location, the light switch 30 redirects the light beams towards a viewer. An image is produced when the light switches 30 are turned on sequentially while the light-intensity distribution on the array light source 60 is synchronically updated. The panel display is capable of responding to an input optical signal by detecting an incoming light beam 80 from a light pen 100. An array of photodetectors 81 is used to identify the location of the incoming light beam 80 on the display panel and a computer is used to execute a corresponding action accordingly.

A packer device, with a commercial name called “Frac Disc” includes an interior packer mandrel and radially surrounding cone, slip and seal system that seals and engages the surrounding casing or other tubular member. The cones expand the slip system and the slips compress and expand the seal system, simultaneously. The slip system provides a means for supporting the seal system when pressure is applied from above or below the packer. The close proximity of the seal and slip system in combination with a separating packer body provides for a very short packer, or a “minimum material packer”, that offers lower cost, higher performance, and if required, faster mill-out.

Decomposing a value range of the respective syntax elements into a sequence of n partitions with coding the components of z laying within the respective partitions separately with at least one by VCL coding and with at least one by PIPE or entropy coding is used to greatly increase the compression efficiency at a moderate coding overhead since the coding scheme used may be better adapted to the syntax element statistics. Accordingly, syntax elements are decomposed into a respective number n of source symbols si with i=1 . . . n, the respective number n of source symbols depending on as to which of a sequence of n partitions into which a value range of the respective syntax elements is sub-divided, a value z of the respective syntax elements falls into, so that a sum of values of the respective number of source symbols si yields z, and, if n>1, for all i=1 . . . n−1, the value of si corresponds to a range of the ith partition.

The present teachings pertain to methods, compositions, reaction mixtures, and kits for mapping a low complexity sequence to a locus in a genome. In some embodiments, the low complexity sequence can be used to determine the methylation profile of a target nucleic acid. A strand-replacing reaction results in a product containing a first strand and a second strand, which can be connected together with a stem-loop adapter to form a single strand. A sequencing reaction can compare the two strands of the product, allowing the experimentalist to both map the sequence to a locus in a reference genome, as well as ascertain the methylation profile of the original target nucleic acid.

Encoding and decoding of digital data using cues derivable at a decoder
ActiveUS20050031219A1Substantial design leewayReduce complexityCharacter and pattern recognitionTelevision systemsDigital dataEncoder decoder
Encoding digital data by using cues at a decoder. An encoder selects an index to indicate a target codeword from the complete space of all codewords to a decoder. The index identifies a group or a set of codewords that contain the target codeword. The sets are represented by a bit-length that is smaller than the code word bit-length thus achieving compression. Two or more codewords in such a set are separated by a predetermined distance and all such sets of codewords considered together form the complete space of all codewords. The encoder sends syntax information, including the index, to specify the decoding. The decoder then uses a set of candidate cues in a comparison operation to determine the target codeword from the indexed set. Processing complexity can be allocated among the encoder, decoder and other possible devices as, for example, in a digital network.

A coder codes an information signal. A rate controller controls a coding rate of the coder in accordance with complexity of the information signal. The rate controller controls a coding amount per unit time in the coding process so that an average value of the coding amount can be approximate to an average rate. The coded data is temporarily memorized in a temporary memory unit and processed by an information processing unit such as a recorder and a transmitter. The information processing unit measures an information processing rate in processing the information. The rate controller adjusts the average rate so that the average rate is lower than the information processing rate measured by the information processing unit, or the rate controller compares a threshold value of a used amount of the temporary memory unit which is previously set and an actually used amount of the temporary memory unit and reduces the average rate when the used amount exceeds the threshold value. Thereby, the rate control can be properly executed while the coding amount in accordance with the complexity of the information signal is allocated.

Techniques are disclosed for optimizing results output by a natural language processing system. For example, a method comprises optimizing one or more parameters of a natural language processing system so as to improve a measure of quality of an output of the natural language processing system for a first type of data processed by the natural language processing system while maintaining a given measure of quality of an output of the natural language processing system for a second type of data processed by the natural language processing system. For example, the first type of data may have a substantive complexity that is greater than that of the second type of data. Thus, when the natural language processing system is a machine translation system, use of a conditional value at risk metric for the translation quality provides for a high quality output of the machine translation system for data of a high substantive complexity (for sophisticated users) while maintaining an average quality output for average data (for average users).

The postage-evidencing symbology is printed in large-format and can include redundant information within an IBI image or between an IBI and visible dark image for a variety of practical purposes. In a preferred form, the images are printed using conventional ink jet printers using water-based inks. In one embodiment of this type, the images are printed with a conventional two-cartridge color ink jet printer by printing postage-evidencing symbology with a single-color ink and printing the visible dark image as a composite dark color from a standard multi-color cartridge.
