Title: Signal Recognition Arrangement Using Cadence Tables
Inventor: ROYBAL LARRY JOHN
IPC: H04M1/00
Filed: 1996-10-31
Abstract: A call classifier (300, 500) for recognizing cadenced signals (100-103) is based on data tables (110, 111) whose contents define the cadences of the signals that need to be recognized. Consequently, the call classifier may be adapted forrecognizing the cadenced signals of various signaling schemes that are used in various countries or telecommunication systems, simply by reprogramming the datacontents of the data tables. Each cadenced signal comprises a different pattern of interleaved signal-on (P) intervals and signal-off (S) intervals. A separate cadence timing table-pair (200-204) corresponds to each sequential S/P interval-pair. Each table-pair includes a P table (210) and an S table (211) each having a plurality of entries (220, 221) each corresponding to a different duration of the corresponding P interval and S interval, respectively, and identifying those signals which have the corresponding P interval and S interval duration, respectively, as candidates for a received signal. The durations of sequential ones of the P and S intervals of the cadence pattern of the received signal are measured (303, 304) and applied (305,306) as pointers to sequential ones of the cadence timing table-pairs to select the corresponding table entries. The selected table entries are ANDed (307) with each other until only one candidate remains in the result (308). The one candidate identifies the received signal. Because reception of a signal can begin anywherewithin the signal's cadence pattern, the table-pairs are initially used (500) to identify when the end of one and the beginning of another instance of the cadence pattern has been received.

Title: Stimulateur cardiaque permettant de verifier la capture auriculaire

IPC: A61N1/365
Filed: 1996-12-17
Abstract: L'invention concerne un stimulateur cardiaque permettant de vérifier la capture auriculaire par un impulsion de stimulation cardiaque auriculaire. Un signal auriculaire est envoyé via une électrode placée dans l'oreillette pendant un certain laps de temps commençant avant la génération de l'impulsion de stimulation et se terminant après la fin de cette dernière. Le signal capté est analysé en détectant si une onde P s'est produite avant la génération de l'impulsion de stimulation cardiaque de telle sorte que cette dernière ait été produite pendant une période réfractaire. En l'absence d'onde P, la pente du signal de forme d'onde détecté est déterminée dans un intervalle de temps sélectionné commençant à un moment sélectionnée après la génération de l'impulsion de stimulation. Un signal d'état de capture est généré qui indique une non capture lors de la détection d'une onde P ou indique une capture en l'absence de composante d'onde P et lorsque la pente déterminée du signal de forme d'onde détecté dépasse un seuil de pente présélectionné délimitant l'état de capture de celui de non capture.
