Granted: 1999-05-11
Abstract: In an electric circuit supplying AC line current to a load (30,31) from an AC source (26) of given frequency providing repetitive cycles, arc detection is provided by sensing cycle to cycle changes in the AC line current. The AC line current is sampled with a harmonic notch filter (72) at a plurality of n phases 0l through 0n during each of a plurality of m cycles of the AC source (26), to provide a plurality of currents In,m, where n is the phase and m is the cycle. The differences (In,m)-(In,m-x), where x is a designated number of cycles, provide a plurality of current difference signals. The absolute values of these current difference signals ID are accumulated in a synchronous summer (94) over the m cycles. An arc indicative signal is generated in response to given conditions and given combinations of conditions (116) of the cumulative absolute current difference signals ID. Cycle to cycle changes in AC line voltage are also sensed with a harmonic notch filter (146), and the arc indicative signal is disarmed in response to a given voltage condition. In further embodiments, subcycle changes are sensed.

Filed: 1994-09-08
Granted: 2000-05-02
Abstract: A rope clamping device for releasably clamping a rope in a substantially loop-shaped configuration adjacent to an end section thereof. The rope clamping device has a base member and a closure member hingely connected together. The base member and the closure member both have an elongated configuration and share a common longitudinal extent. The base member has a channel extending longitudinally therethrough. An abutment shoulder extends radially inside the channel. The base member also has a groove on its top surface. The closure member has a set of rope gripping elements projecting from its lower surface. The rope is adapted to be first tied into a knot adjacent to the end section and threaded though the channel with the knot abutting against the abutment shoulder. The rope is then adapted to be formed into a loop adjacent to the knot and a rope segment is adapted to be rested inside the groove.      In order to releasably lock the rope in the loop configuration, the closure member is then pivoted until the base member abuts against the closure member with the rope gripping means, preventing longitudinal displacement of the rope segment inside the groove.

Abstract: Un procédé et un appareil permettent d'optimiser la performance d'un simulateur cardiaque sensible aux fréquences. On obtient ainsi un stimulateur cardiaque capable d'obtenir et d'enregistrer des informations sur la fonction cardiaque d'un patient et sur le fonctionnement du stimulateur cardiaque pendant un bref exercice. Les données ainsi recueillies concernent des informations sur le nombre d'événements cardiaques pendant chaque durée de deux secondes de l'exercice, ainsi que le pourcentage d'événements rythmés pendant chaque intervalle de deux secondes. Des données qui traduisent la sortie du capteur de l'activité du stimulateur cardiaque sont également recueillies pendant chaque intervalle de deux secondes de l'examen. En outre, des données sur l'intervalle atrioventriculaire de chaque cycle cardiaque pendant l'examen sont recueillies. Ces données sont analysées pour déterminer si elles traduisent des intervalles atrioventriculaires de rythme auriculaire en sens ventriculaire ou de sens auriculaire en sens ventriculaire. Ce stimulateur cardiaque est utilisé avec une unité extérieure de programmation/traitement de données qui reçoit les données enregistrées après la fin de l'exercice de test. Les données sont traitées et présentées sur l'écran du programmeur d'une manière qui permet au médecin de les assimiler aisément et d'observer les effets de changements hypothétiques de la programmation de la réponse aux fréquences du stimulateur cardiaque. En outre, le médecin peut observer les profils d'adaptation au rythme atrioventriculaire associés à la performance atrioventriculaire réelle du patient et comparer ces données avec un profil atrioventriculaire typique d'un coeur sain.

Title: Linear prediction coefficient generation during frame erasure or packet loss
Inventor: CHEN JUIN-HWEY
IPC: G10L19/04
Filed: 1995-02-13
Granted: 1998-10-06
Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech. During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only. This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Title: Method for preparation and transplantation of volute grafts and surgical instrument therefor
Inventor: HUGHES STEPHEN E
IPC: A61F9/007
Filed: 1993-09-10
Granted: 2003-11-25
Abstract: A method of transplant-ing a graft in the subretinal area of a host eye comprises prepar-ing the graft by harvesting from the donor tissue a population of cells in a manner that main-tains the population of cells in the same organization and cel-lular polarity as is present in normal tissue of that type. The population of cells are of a sheet-like from and are assem-bled with a relatively thin flex-ible pliable carrier composed of a non-toxic flexible compo-sition which substantially dis-solves at body temperature to form a graft. The graft is suf-ficiently flexible and pliable to be coiled to form a volute (76) without disturbing the organi-zation and polarity of the cells. The method further comprises coiling the graft to form a vo-lute (76) with the convolutions of the volute (76) free of one another for subsequent uncoiling of the graft substantially to its original sheet-like form. An incision is made in the host eye for insertion of the volute (76). The incision in the eye is smaller than the incision that would be required for insertion of the graft in its uncoiled sheet-like form.  The volute is inserted one end first into the host eye through the incision and transported to a position between the retina and the underlying tissue. The volute (76) uncoils after its insertion to lie in sheet-like form between the retina and underlying tissue of the host eye. The incision is then closed.
