Title: Transmitter for qam encoded data
Inventor: DENT PAUL W
IPC: H04L27/20
Filed: 1997-05-19
Abstract: Quadrature Amplitude Modulated signals are generated from data bits by using a first Quadrature Phase Shift Keying (QPSK) modulator for encoding a first pair of the data bits into one of four carrier signal phases, thereby producing a first QPSK signal. A second QPSK modulator encodes a second pair of the data bits into one of four carrier signal phases, thereby producing a second QPSK signal. The first QPSK signal is amplified to a first power level, and the second QPSK signal is amplified to a second power level. The first and second amplified signals are then combined to produce a signal in which four data bits are encoded. In another aspect of the invention, a new type of modulation, called Offset Quadrature Phase Shift Keying (OQPSK), is used in place of the first and second QPSK modulators, so that an Offset Quadrature Amplitude Modulation (OQAM) transmitter is formed.

Abstract: Un système d'implant cochléaire implantable autoajustable (46) comprend une partie implant (50) et une partie externe (53). Le système comporte un dispositif et un moyen permettant de déterminer de manière objective des paramètres psycho-physiques sélectionnés tels que le seuil de stimulation, le niveau de confort et la résolution de sonorité, utilisée par la portion implant comprenant un stimulateur cochléaire implantable (ICS), lorsqu'il assure sa fonction de stimulation. L'entrée au système est une stimulation électrique. Les sorties du système comprennent un réflexe de l'oreille moyenne (MER) et des potentiels évoqués tels qu'un potentiel d'action composé (CAP) le long des chemins auditifs/cérébraux, tous deux sont détectés au moyen d'outils et de techniques de mesures objectives. Selon un mode de réalisation, le procédé d'ajustement utilise le réflexe MER pour déterminer la valeur seuil grossière puis, en utilisant cette valeur seuil grossière comme point de départ, il a recours aux potentiels invoqués afin de déterminer une valeur seuil fine ou plus précise, afin d'entrer à zéro à un niveau désiré. Une telle méthode du zéro est appliquée de préférence à l'aide d'un circuit implanté (par exemple un circuit faisant partie de ICS) et utilisant une électrode implantée dans l'oreille moyenne (54) et une électrode cochléaire (56) ainsi qu'un circuit d'amplification (58, 64), de filtration (60, 66) et de traitement (62, 68, 67) afin de déterminer respectivement la réponse MER et les potentiels invoqués. Un autre mode de réalisation consiste à utiliser la présence ou l'absence de MER afin de régler l'intensité et la stimulation électrique en continu et automatiquement, ce qui évite au patient d'avoir à effectuer des réglages manuels lents et fastidieux de la commande de sonorité d'un processeur de la parole utilisé avec le ICS.

Title: Arrangement for use in a system with a range of dental screws, and the range of dental screws
Inventor: HANSSEN HALVAR
IPC: A61C8/00
Filed: 1997-08-25
Abstract: In a system with a range of dental screws (2), the screws are tightened by means of one and the same screw tightener (1). The screws are of different types and have different constructions. Each screw has an internal recess (4) via which the cooperation with the screw tightener is afforded. Each recess has elements extending inwards towards the centre axis of the screw, and the screw tightener has parts which can cooperate with the elements. The bearing capacity function is effected by the conicity of the said parts, while the driving function between tightener and screw is effected by means of axially extending elements and parts. The driving and the bearing capacity are in this case mechanically separated.      The invention may also be seen as a range of dental screws.

Title: Speaker verification method
Inventor: VAN KOMMER ROBERT
IPC: G10L17/00
Filed: 1996-10-15
Abstract: Method for enabling a user of a system to obtain access to one or more services, for example for enabling a caller to access some information on a remote server. The method comprises the following steps: the system first prompts the caller to identify himself by entering a subscriber code (121). A speaker verification is then made using a voice comparison between the caller's voice and a voice reference (123) associated with the subscriber the caller claims to be. Access to the requested services is given if the outcome of said voice comparison is positive; if the system does not store a sufficiently good voice reference to verify the identity of the subscriber the user claim to be with a predetermined degree of reliability, the caller is prompted to enter a confidential PIN code (122). If the PIN code entered is correct, access to the requested services is given and a new voice reference is stored.

Title: Transporting user data over a-bis and a-interfaces within a mobile telecommunications network
Inventor: GALYAS PETER
IPC: H04B7/26
Filed: 1997-10-28
Abstract: A synchronization frame is first formated and transmitted in accordance with the Global System for Mobile (GSM) 08.60 specification. After an initial synchronization procedure is accomplished between a transcoder/rate adaptor (TRAU) (40) and a particular base transceiver station (BTS) (50) serving a mobile station (60), a modified GSM 08.60 frame is thereafter used to transport greater user data payload across the established communications link. The modified frame replaces the synchronization bits included in the GSM 08.60 formatted data frame with user data to increase data payload from the conventional 13.5 Kbit/s to a more desirable 14.4 Kbit/s without altering the standardized 16 Kbit/s transmission rate supported by the IWF and the BTS  (50).
Patent CA-2274846-A1 (CA)
Inventor: PAUL PATRICK J
IPC: A61N1/37
Filed: 1997-12-11
Abstract: An implantable cardiac stimulator (10) for detecting capture or adjusting the strength or duration of pacing pulses by using an evoked response detector (41) and periodically tuning (334) the evoked response detector. When the electric evoked response detector is to be tuned, capture is verified by detecting the mechanical evoked response, as the magnitude of the stimulating pulse is adjusted to isolate the threshold as detected by the mechanical response detector (42). At the same time, the electrical evoked response is also monitored. The difference between the detected electrical signal following capture as detected by the mechanical response detector and the signal following non-capture is used to tune the electrical evoked response detection apparatus and algorithm. The energy of the pacing pulse can then be optimized (232) by adjusting both strength and duration. A very small safety margin is needed since capture is continuously monitored by the electrical evoked response apparatus and a safety pulse is immediately applied if capture is lost. The safety pulse can be applied in the same cardiac cycle so that the heart beat remains controlled.

Title: Method for securing over-the-air communication in a wireless system
Inventor: PATEL SARVAR
IPC: H04L29/06
Filed: 1999-07-20
Abstract: In the method for securing over-the-air communication in wireless system, a mobile sends a system access request and dummy data associated with the system access request to a network. The network sends a first data stream including a first data portion to the mobile in response to the system access request and the dummy data. The mobile extracts the first data portion from the first bit stream, and sends a second bit stream to the network. The second bit stream includes a second data portion. The mobile and the network both generate a key based on the first data portion and the second data portion, and establish a first encrypted and authenticated communication channel in cooperation using the key. The mobile then transfers authorizing information to the network over the fist encrypted and authenticated communication channel. If accepted, a second encrypted and authenticated communication channel is established. The network then sends sensitive information such as the root or A-key to the mobile over the second encrypted and authenticated communication channel.
