Title: Procedure for quantification of coefficients
Inventor: CROCITTI VALERIE
IPC: G06T9/00
Filed: 1995-06-20
Granted: 2007-02-06
Abstract: The disclosure concerns a procedure for quantification of coefficients in a variable data rate image compression system, in the form of blocks and macro-blocks, said system including means of transformation of blocks of pixels into blocks of coefficients, means of quantification of these coefficients, means of storage of coded information before transmission, and means of regulation of means of quantification as a function of the state of the means of storage. The procedure is such that each image being divided into groups of blocks, at least when a so-called current image must be coded in inter mode, a quantifier is determined at the start of the current image, said quantifier being corrected by a correction coefficient recalculated before the quantification of at least one of said groups, said coefficient being a function of the difference between, first, the number of bits produced for all the groups of blocks previously coded and, secondly, a prediction of this number of bits, said prediction being based on the distribution of the bits during the coding of at least one image preceding the current image. The invention is applicable notably in the field of image compression at low data transmission rates.

Title: Laser with readily exchangeable wavelength selective feedback element
Inventor: KASHYAP RAMAN
IPC: H04B10/43
Filed: 1994-03-18
Granted: 1999-10-05
Abstract: A laser having two feedback elements (17, 11), at least one which (11) is wavelength selective, is provided with a demountable optical connector (3, 13) located between the gain medium of the laser and the wavelength selective feedback element (11). An optical waveguide (3, 13) is utilised to direct optical radiation between the demountable optical connector (3, 13) and the wavelength selective feedback element (11). The demountable optical connector for example a mechanical fibre connector (3, 13), allows the wavelength selective feedback element, for example a fibre grating, to be exchanged cheaply, simply and quickly, and thus allows the wavelength of operation of the laser to be altered.

Title: Method and system for managing telecommunications such as telephone calls
Inventor: WOLFF RICHARD SAUL
IPC: H04M3/436
Filed: 1994-02-17
Granted: 1998-11-03
Abstract: A method and system for managing telephone calls includes a personal telephone manager (PTM) (12) and uses out-of-band, wireless, two-way signaling, messaging and alerting to screen, control, route and respond to incoming telephone calls and to communicate called party text messages in auditory form to the caller. Using an out-of-band signaling/messaging path (16), the PIM (12) frees the called party from the need to maintain telephone network connectivity, from having to inform others of his/her current location, and from having to subscribe to and use cellular telephone service. Two-way wireless data messaging to a portable computer (18) equipped with radio transceivers is also provided. This feature enables the system to provide a set of real-time options including: call screening by the called party based on information identifying the caller's telephone number, call redirection to a wireline or wireless telephone number as specified by the called party; call redirection to a third party or to a voice mail system; or the return of a text message specified by the called party to the caller in auditory form.

Title: Dual level tilting tray package sorting apparatus
Inventor: BONNET HENRI
IPC: B65G23/10
Filed: 1994-11-09
Granted: 2001-08-21
Abstract: An automatic system (10) for sorting items, such as small parcels, into groups bound for different geographical locations is described. The system uses tilting trays (60, 90) arranged at multiple levels, with all the trays being mounted on carriages (14) travelling on a single monorail (12). The trays are tilted at the proper output chutes by cam roller mechanisms which are appropriately inserted into the path of cams on the trays under the coordination of a digital controller. A simple drive mechanism (16) moves the carriages (14) along the monorail (12) using a drive roller which presses against the carriages. The carriages may be linked by a pliable linkage assembly (150) that does not include mechanical hinges or like mechanisms. The system is easy to repair and operates at low noise levels.

Granted: 2009-07-07
Abstract: Prosaposin and peptide derivatives derived therefrom will promote neurite outgrowth in vitro. A peptide consensus sequence was determined by comparing the active neurite outgrowth-inducing saposin C peptide sequence with that of various hematopoietic and neuropoietic cytokines. These cytokine-derived peptides will promote the sam e processes as their corresponding cytokines. In addition, prosaposin and saposin C promote increased nerve cell myelination ex vivo.</ SDOAB>

Abstract: Coupling between two side circuits and a phantom circuit in a quaded cable (200) is compensated for at the receiving end of a transmission system.  Known signals are separately transmitted on each circuit and coupling between each circuit is estimated based on a measured signal received at the receiving end of the quaded cable for initialization.  During data transmission, received data signals are modified in accordance with the initially determined coupling to produce estimated transmitted data signals.  Reestimation of the coupling between each circuit is performed during data transmission by storing (303) N received data signals and N estimated transmitted data signals on each circuit.  The coupling between circuits is determined as a function of the covariance of the N received signals and covariance of the N estimated transmitted signals on each circuit.  The reestimated coupling is used to modify (302) subsequent received data signals on each circuit.

Abstract: A  local  information  extracting  portion  11  extracts  a plurality of ridge line candidate images for each of local regions into which an  image has been divided.   A first ridge  line candidate image selecting portion 12 selects a first ridge line candidate image that has high likelihood of a ridge line for each local region.  A connectivity evaluating portion 13 evaluates the connectivity of first ridge line candidate images between each local region.   A clustering portion 14 clusters local regions corresponding  to  the  evaluated  result  of  the  connectivity evaluating portion 13 and generates a local region group.   A cluster evaluating portion 15 determines an initial local region group that is a local region group having high likelihood of a ridge line.  A ridge line image restoring portion 16 outputs a first ridge line candidate image for each local region that is included in the initial local region group.   In addition, the ridge line image restoring portion 16 outputs an optimum ridge line candidate image for each local region that is not included in the initial local region group as the extracted result of a ridge line.

Abstract: A protocol appropriate for smartcard purchase applications such as those that might be completed between a terminal or ATM and a users personal card is disclosed.  The protocol provides a signature scheme which allows the card to authenticate the terminal without unnecessary signature verification which is an computationally intense operation for the smart card. The only signature verification required is that of the terminal identification (as signed by the certifying authority, or CA, which is essential to any such protocol). In the preferred embodiment, the protocol provides the card and terminal from fraudulent attacks from impostor devices, either a card or terminal.

Abstract: A curtain bottom tensioning assembly comprised primarily of a resilient memb er (50) extending across the bottom of the door (10). The resilient member (50)  is directly or indirectly coupled to a guide extension (100) extending beyon d the leading edge of the door (10) and engaging vertical guide members (20, 3 0) to guide the door (10) in a vertical plane. The guide extensions (100) also engage the vertical guide members (20, 30) to restrict the guide extensions (100) from moving horizontally toward the curtain (10). The coupling between  these horizontally restricted guide extensions (100) and the resilient membe r (50) places a tension on the resilient member (50). The resilient member (50 ) is thus stretchedacross the bottom of the door or curtain (10), and serves a s a bottom bar that also substantially conforms to or deflects around an obstruction, thus preventing or minimizing damage to the door (10), the bott om bar and the obstruction.
