Abstract: In a communication system, a network has nodes each connected in a star relationship to a number of end units that include means for assuming one of an idle, active, or on-line state and for requesting the node to which it is connected to change it from the idle to the active and the active to the on-line state, and for releasing the on-line state on the basis of data at the end unit. The nodes for change the state of an end unit from the idle to the active and from the active to the on-line mode on the basis of available communication time.      According to an embodiment of the invention, the nodes change the states to the on-line state on the basis of policy preferences for the type of traffic, and specifically to grant priority to stream traffic over batch traffic.

Abstract: A method for preparing cathode material for use in lithium secondary batteries comprising the steps of: (a) mixing first and second reactants in a appropriate stoichiometric ratio to form a reaction mixture, wherein the first reactant is represented by LixMO2, M is either Ni or Co, and x is a variable from 0.25 to 1.1, and the second reactant is V2O3, V2O5, or NH4VO3; and (b) sintering the mixture in air at temperatures between 650°C ~ 700°C for 1 ~ 2 hours to obtain a cathode material represented by LiMVO4. The first reactant can be obtained by an aqueous-phase reaction by mixing a first aqueous solution, which contains M(NO3)2.6H2O, and a second aqueous, which contains LiOH.H2O, Li2O, Li2CO3, or Li(CH3COO), to form a precursory aqueous solution, and drying the precursory aqueous solution. Very high purity cathode materials can be obtained at a substantially reduced reaction time and substantially reduced reaction temperature, both of which will contribute to reduced production cost. The lithium secondary batteries so prepared can provide discharge voltages between 4.5 ~ 4.9 volts.

Title: Code division multiplex signal receiving method
Inventor: MIKI YOSHINORI
IPC: H04B1/69
Filed: 1995-04-21
Granted: 1998-12-15
Abstract: A determinant expressing the relation between the sequence of symbol vectors b(k) transmitted from L communicators through code division multiplexing and the sequence of compressed-back output vectors y(k) of received signals taking the cross correlation of the spread-spectrum sequence of the sequence of the vectors b(k) into account is limited within the range of from k-g to k+g where k is the symbol timing and g is the symbol time. The compressed-back outputs of the received signals within the limited range are inputted to a shift register having 2g+1 stages. A partial correlation matrix calculating section (26) calculates partial correlation matrixes Rk+h (1), Rk+h (0), and Rk+h (-1) with respect to h=-g,..., g at every symbol interval within the limited range.  An inverse correlation matrix calculating section (27) produces the correlation matrix Rk for the spread-spectrum sequences which respectively corresponds to the L communicators from the partial correlation matrixes and calculates the inverse correlation matrix Rk-1 of the correlation matrix Rk. A  multiplier (25) produces an estimated sequence of symbol vectors by calculating the product of the inverse correlation matrix Rk-1 and the sequence Yk of the compressed-back outputs y(k) from the register (24).

Abstract: The present invention relates to an echo canceler for training an echo path estimation without providing a hindrance to a speech.  The echo canceler of the present invention includes a pseudo noise generator for generating a certain pseudo noise.  This pseudo noise is forcibly supplied to a transmission line for transmitting a far-end talker's voice.          Here, in the case where the far-end talker's transmitting speech level is faint or the far-end talker is in a speechless condition, a certain correlation is established between the pseudo noise and a signal of the transmission line for transmitting the near-end talker's voice.  Based on such a correlation as just mentioned, a coefficient for generating an echo replica is calculated.  Therefore, a training for estimating an echo path is performed based on the pseudo noise and without depending on the far-end talker's voice, thereby enabling to generate an appropriate echo replica.

Abstract: An improved method and system for storage of geographic data on physical storage media. The geographic data are stored in a manner that facilitates and enhances use and access of the data by various navigation application functions in navigation systems that use the data. The geographic data includes a parcelization that separates the geographic data into parcels having less than or equal to a maximum parcel size but having at least a desired fill percentage. The parcelization method also provides for a division arrangement that facilitates addressing and identification of the parcels. According to a further aspect, thegeographic data includes special nodal entities that are used to collapse complex intersections, such as roundabouts, cloverleaves, and divided highways, into simpler data representations. The special nodal entities are associated with road segment data entities and used in a route calculation program in place of regular node entities. Further, the geographic data include a normalized attribute array that includes reoccurring combinations of certain selected attributes of the geographic data. Indices to the array are included in place of data corresponding to the selected attributes. When a navigation application program requests data, an entry in the normalized attribute table pointed to by an index in the data is used to return the requested data in the particular combination of attributes from the normalized attribute array. The geographic data is compiled by a method that facilitates access to the data on a physical medium. According to the compilation method, data files to be stored on the medium are organized into parcels. The data records within the data files are identified by the parcel in which they are located. An arrangement of all the data files on the medium is determined and a parcel identification related to the medium is assigned to each parcel. Cross references between data records areupdated to include the assigned parcel identifications and the parcels are stored on the medium.
