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.

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.

The digital video referencing frame image is compressed block by block by applying lossless compression algorithm to pixel components with full length, or 1 bit, 2 bits, 3 bits or 4 bits LSB bits truncation. If a sub-block has high complexity which results in more than 3 bits error for most pixel components, a transfer algorithm with quantization and VLC coding is applied to compress this sub-block. Should the complexity is higher than a threshold or at least one sub-block having error of more than 3 bits for most pixel components, truncating 1 LSB bit of sub-block with simple pattern to save more bits to be allocate to code the sub-block with highest complex pattern.

A conference bridge is provided for managing a conference between media signal sources generating media data packets conveying encoded media information and encoding type information. The media signal sources, in order to enter a conference, generate link messages including respective supported encoding types and transmit the link messages to the conference bridge. The conference bridge receives the link messages and processes them to derive a first common encoding type supported all media signal sources in the conference and a second encoding type supported a subset of media signal sources in the conference. The conference bridge generates link message reply signals conveying the first encoding type and the second encoding type the subset of media signal sources and conveying at least the first encoding type to the media signal sources other than the subset of all media signal sources. Each media signal source is responsive to the link message reply signal to render active at least the first encoding type and selectively render active the second encoding type.

A system (100) to enable the transfer of Internet protocol (IP) format data (12, 14) over a point-to-multipoint passive optical network (PON, 16) is illustrated in FIG. 2. An exchange (102) is connected to a plurality of outstations (104-108) via an optical communication resource (24, 26-38) including a passive optical splitter (22) providing isolation to individual outstations. Media access control of the plurality of outstations is administered by the exchange (102), with collision detection logic (112) in the exchange determining collision (158) of Internet protocol (IP) encoded data communicated thereto through the PON (16). The IP encoded data realises a transport mechanism through the PON. Each of the plurality of outstations (104-108) and the exchange (102) is adapted to pass data in an IP format to and from the optical communication resource such that IP encoded data is transported, in use, directly between the outstation and the exchange.

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 s_i 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 s_i yields z, and, if n>1, for all i=1 . . . n−1, the value of s_i corresponds to a range of the i^th 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 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.

The present invention provides an antenna-array-based multiple-input multiple-output orthogonal-frequency-division-multiplexing (MIMO-OFDM) system and a pre-coding and feedback method used in the same. The present invention uses QR decompositions of the MIMO channel matrixes to parameterize the channel state information (CSI) of every OFDM frequency band. In addition, the present invention feeds back the information related to θ and φ in the Givens rotation matrixes of the partial frequency bands and then uses an interpolation method to generate θ and φ in the Givens rotation matrixes of all the frequency bands, which further is able to represent the CSI of all the frequency bands. In this way, the present invention has advantages of low complexity and low feedback rate requirement.

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).

Machine-readable light-colored or invisible, but luminescent, postage-evidencing symbology and dark, readable other postage information are printed, preferably in a single print operation, to provide large amounts of information without diminishing read rates. The resulting combination image can be printed independent of substrate material to enable the provision of a high information density without obscuring any one component. 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.
