Abstract: A data processing system and method for generating a representation of an electronic document, for indexing the electronic document, for navigating the electronic document using its representation and for displaying the electronic document on an output device. The system and method are used with electronic documents having descriptive markup which describes the content or meaning of the document rather than its appearance. Such documents may be represented by a tree. Each markup element defines a node or element in a tree. The tree is represented by providing a unique identifier for each element and for accessing a descriptor of the element. An element descriptor preferably includes indications of the parent, first child, last child, left sibling, right sibling, type name and text location for the element. The document representation is used to facilitate navigation of the text for constructing navigational aids such as table of contents and full text indexing.

Abstract: A method of formatting digital data and a method of decoding the formatted digital data. User selectable format parameters vary the dimensions and other attributes of spots and the cells containing those spots as well as other features which the formatting process formats into a pattern. A method of encoding the formatted digital data using these format parameters allows for encoding a substrate optimally for any given printer or scanner. One embodiment provides for markers to facilitate determination of cell locations. In one embodiment the decoding process achieves a pyramid gain of knowledge by locating a landmark (801), which is located in a known position relative to a metasector (802), which contains information about the encoding process used to encode the main body of data (803), which the decoding process decodes to recover the original digital data. Further embodiments include encryption, transmission by facsimile, inclusion of human readable information, and automatic launches of computer files.

Abstract: A DS-CDMA transmission method capable of improving the accuracy of channel estimation using pilot symbols by eliminating cross-correlation between pilot symbols inserted into code channels in CDMA multiplexing carrying out fast signal transmission. In each frame assembler, the pilot symbols, which are used for channel estimation for coherent detection, are inserted into coded information data on code channels at fixed intervals, and then the data is modulated by the modulator. The modulated data symbols in each code channel from the modulator are spread by the spreading modulator, the pilot symbols are spread using a spreading code, whereas the information symbols are spread using different spreading codes assigned to respective code channels. The spread signals of the code channels are summed up by the adder to be transmitted.

Abstract: A cassette adapter for coupling audio signals from an external source to a cassette player for reproduction by the cassette player. The adapter is user-configurable for use in cassette players of the side-load and front-load type. Additionally, the user-configurability of the adapter overcomes problems inherent in prior art adapters, such as the tendency for the fraying and cutting of the connections between the prior art adapters and the sources of the audio signals. The adapter includes a cassette-shaped housing, a record head disposed in the housing in a position substantially adjacent to a playback head of the cassette player when the adapter is inserted in the cassette player, a connector detachably connectable to a complementary connector, the connector positioned along a peripheral wall of the housing, and a conductive circuit coupled to the record head and the connector.

Abstract: A CDMA communication method capable of providing a multi-rate user with high quality transmission using a spreading sequence selected from sequences which consist of multilayer sequences arranged in a hierarchical tree structure. A higher level sequence C.sub.16 (1) and its inverted sequence C.sub.16 (1) are included in its lower level sequences {C.sub.32 (1), C.sub.32 (2)} and {C.sub.64 (1), C.sub.64 (2), C.sub.64 (3), C.sub.64 (4)}, for example, and a sequence from a higher level is selected to transmit a higher rate data: The C.sub.16 (1) is used to transmit data whose peak rate is twice the peak rate of the data transmitted using its lower level sequences {C.sub.32 (1), C.sub.32 (2)}, and four times (=2.sup.2) that of the data transmitted using the sequences {C.sub.64 (1), C.sub.64 (2), C.sub.64 (3), C.sub.64 (4)}. The C.sub.16 (l), however, cannot be selected if any one of its lower level sequences {C.sub.32 (1), C.sub.32 (2)} and {C.sub.64 (1), C.sub.64 (2), C.sub.64 (3), C.sub.

Abstract: The invention disclosed herein provides toy objects such as action figures, robots, vehicles, creatures, etc., with apparatus for playing a shooting game controlled by one or more human players. Each toy object includes either a energy emitter, a energy sensor, or both. The toy objects are manipulatable by the players to face the emitters and the sensors in directions to hit other objects with radiated energy or avoid being hit with radiated energy from other objects. In the preferred embodiment, the emitter radiates infrared light and the sensor detects infrared light, and are operated from a backpack movably attached to an action figure. Control of radiating and detecting infrared light is similar to the control in a currently popular "laser" shooting games available from Toymax Inc. under the trademark "Laser Challenge".

Abstract: A spread spectrum portable telephone apparatus operates with long wait times and with little battery depletion while waiting. A mobile unit receiver receives and detects radio signals, analog-to-digital (AD) converts the detected reception signals, waveform-shapes the converted signals, despreads and decodes the waveform-shaped signals with a spread signal, frame-resolves the decoded signals, and extracts reception date from the frame-resolved signals. A data receiver is included which has, for both a pager channel and a communications channel, a narrow band AD converter circuit, a narrow band reception filter for waveform-shaping the AD converted signals, and a correlator which despreads and decodes the waveform-shaped signal using a spread code generated by a low speed spread code generator circuit. When waiting, calls to the apparatus are waited for with the power turned on only to the paging channel data receiver.

The refrigerating system has a separator vessel, a recuperative heat exchanger, and a heat-regulating valve controlled by the coolant pressure and temperature at the cooling skirt inlet, and also fitted in series with the separator vessel in the line connecting the condenser inlet to the evaporator. The separator vessel is connected by a gas phase to the coolant feed duct.

Abstract: A method and apparatus for creating, storing, identifying, transferring, managing and searching databases of information related to subjective works, such as art, music, film, dance, theater or other fields generally recognized as requiring subjective human judgment by an "expert" to make subjective, objective, or mixed decisions regarding value, interest, and relationships one to another. The invention may be embodied in a general purpose digital computer programmed to host routines operating by deterministic logic, fuzzy logic, or both. A user may input information related to the nature or type of item requested and receive identification of a subjective match for the item. The routines may utilize a thesaurus and processes for relaxing search requirements to assure a match. In one embodiment, an expert system resident in a computer may create, manage and rapidly search databases of subjectively characterized items, such as art works, music, or real estate, for example, by unique characteristics.

Abstract: Enabling reception quality to be improved and the capacity in terms of the number of simultaneous users in a cell to be increased, and speeding up the establishment of spreading code synchronization and the convergence of weighted coefficients, by feedback controlling weighted coefficients such that desired signal power to interference power ratio (SIR) becomes maximum. A coherent adaptive diversity configuration is employed to which absolute coherent detection is applicable. Adaptively feeding weighted coefficients back to diversity branches makes it possible to reduce the influence of the interference power from other users, and thus to increase the capacity in terms of the number of simultaneous users in the cell. Furthermore, the direction that provides the maximum received SIR is determined while rotating antennas in a state of having directivity with a predetermined angle range.

Abstract: A device for shifting data in a cascade multiplexer shifter allows the shifter to be used in a full-length mode or in a split mode where the shifter is divided into two equal halves with upper and lower half fields thereof respectively receiving individual data numbers. Each data number is thereafter simultaneously shifted right or shifted left a given shift amount to effect a dual right or dual left shift function.

Abstract: Bar codes, comprised of black and white stripes, are shown to be a finite topic, and the optimum bar code methodology is binary coded binary, BCB. Binary digits are utilized to represent bar coded messages and each binary digit is immediately complemented, forming two independent but binarily complemented messages in one bar code symbol. BCB represents given information in less space than, e.g., Interleaved 2 of 5 and Code 39, while using the same x width (the width of a module), and BCB is far more versatile and is easier and less expensive to print and scan. BCB avoids misreads more reliably and achieves a dramatically higher first time read rate through use of error correcting bar codes.

Abstract: A concrete circuit configuration is proposed of a multiplex transmitter for loading a standard ATM cell with multiplexed micro-frames which are each shorter than the standard ATM cell. The input micro-frames are delivered to a distributor 504 in the input order through an interface 503. The distributor 504 distributes the input micro-frames using distributing information input. The distributing information accords with the service condition of each connection or micro-frame. An extracting circuit 506 selects buffers in accordance with predetermined buffer selection logic. A cell cancellation monitor circuit 508 relinquishes micro-frames exceeding cell tolerable time periods T2-1-T2-m. A multiplexing processor 507 transfers the cell or a idle cell to a sender 511 in accordance with the cell transfer timing of the sender 511.
