Title: Speech encoding device, speech decoding device, and method thereof
Inventor: OSHIKIRI MASAHIRO
IPC: G10L19/02
Filed: 2008-02-29
Abstract: Disclosed is an encoding device which can accurately specify a band having a large error among all the bands by using a small calculation amount. The device includes: a first position identification unit (201) which uses a first layer error conversion coefficient indicating an error of decoding signal for an input signal so as to search for a band having a large error in a relatively wide bandwidth in all the bands of the input signal and generates first position information indicating the identified band; a second position identification unit (202) which searches for a target frequency band having a large error in a relatively narrow bandwidth in the band identified by the first position identification unit (201) and generates second position information indicating the identified target frequency band; and an encoding unit (203) which encodes a first layer decoding error conversion coefficient contained in the target frequency band. The first position information, the second position information, and the encoding unit are transmitted to a communication partner.

IPC: B05D1/12
Filed: 2008-06-30
Abstract: The present invention refers to a method for preparing a superhydrophobic surface on a solid substrate comprising the steps of (a) providing a solvent in the form of a pressurized fluid in a vessel, wherein the fluid exhibits a decrease in solvency power with decreasing pressure; (b) adding a hydrophobic substance to the solvent as a solute, which substance is soluble with the pressurized fluid and has the ability to crystallize/precipitate after expansion of the fluid, thereby obtaining a solution of the solvent and the solute in the vessel; (c) having at least one orifice opened on the vessel, thereby causing the pressurized solution to flow out of the vessel and depressurize in ambient air or in an expansion chamber having a lower pressure than within the vessel, the solute thereby forming particles; and (d) depositing the particles on the substrate in order to obtain a superhydrophobic surface.  Hereby, a pressurized fluid which expands rapidly as a result of depressurization is used to prepare the superhydrophobic surface, thereby facilitating the preparation of the surface. Moreover, the invention refers to an arrangement for preparing a superhydrophobic surface on a substrate, a superhydrophobic film prepared by the method of the invention, and a substrate having deposited thereon the superhydrophobic firm.

Patent CA-2699831-A1 (CA)
Inventor: BASTOS RIBEIRO RENATO
IPC: F03B7/00
Filed: 2008-10-03
Abstract: The present disclosure relates to an apparatus and associated methods for generating energy by capturing and taking benefit of the energy generated by any quantity of air surfacing inside water.  The apparatus includes a frame structure (102) to which is rotatably mounted an upper drive wheel (104), a lower wheel (106), and a vertical fluid column container (108). An endless chain (110) of gas capsule elements (112) is mounted on the upper and lower wheels (106, 108). This endless chain (110) passes vertically up into and through the fluid column container (108) through a seal port (118) in the bottom of the container (108). As the endless chain (110) of gas capsule elements (102) passes vertically through the fluid (109) in the container (108), fluid pressure on the elements (110) due to the height of the column of fluid in the container (108) produces a net bouyant force upward on the elements (112), causing them to rise, generating kinetic energy that turns the wheels (106,108).

Abstract: The present invention relates to 11.beta.-fluoro-3-acetoxyestra-3,5-dien-17-one as a suitable intermediate in the preparation of 11-fluoro-subtituted steroids and to the process for preparation thereof. For this purpose, 11.alpha.-hydroxyestra-4-ene-3,17-dione is reacted with 1 to 3 equivalents of n-nonafluorobutanesulfonyl fluoride and 3 to 5 equivalents of diazabicycloundecene (DBU) at -40 to -20°C in an organic aprotic solvent and, after an aqueous workup, reacted with 5 to 10 equivalents of acetic anhydride and 0.01 to 1 equivalent of a strong acid. The desired product precipitates spontaneously out of the reaction solution and is obtained in a very high purity by filtration. The process is notable for the very high yield, avoidance of a chromatographic purification of the product, a reduced proportion of wastes and significantly increased process throughput. The process according to the invention is therefore especially suitable for preparing 11.beta.-fluoro-3-acetoxyestra-3,5-dien-17-one on a large industrial scale.

Title: Preamble design for a wireless signal
Inventor: KHANDEKAR AAMOD
IPC: H04L5/00
Filed: 2008-11-10
Abstract: Providing for base station (BS) acquisition in semi-planned or unplanned wireless access networks is described herein. By way of example, a signal preamble can be dynamically allocated to wireless signal resources, such that the preamble is scheduled to different resource(s) across different cycles of the signal. Dynamic allocation can be pseudo-random, based on collision feedback, or determined by a suitable algorithm to mitigate collisions from a dominant interferer. In addition, dynamic scheduling can be particular to a type of BS to significantly reduce collisions from BSs of disparate types. In at least one aspect, a preamble resource can be subdivided into multiple frequency sub-carrier tiles. Control channel information can be transmitted on each tile of a group of such tiles, further mitigating effects of a dominant interferer on a subset of the tile group.

Abstract: The present invention is made to provide an information distribution system capable of securely storing digitized personal information in an encrypted state in a storage section and securely transferring/disclosing the stored digitized information only to a particular third person via a network. Communication of the information is securely performed in the encrypted state between information terminals connected to the communication network (between a client and a server or between peer-to-peer client terminals). An information terminal which has created information encrypts the original information by a common key generated upon communication and stores the information in a secure storage of one of the information terminals connected to the communication network while maintaining the encrypted state.  Further, the system creates a mechanism for authenticating a person having a particular authority for viewing the encrypted information and index information having an encrypted common key and link information indicating the location of the information for supply to a user.
