Patent CA-2153442-A1 (CA)
Inventor: MUNROE STEVEN JAY
IPC: G06F12/02
Filed: 1995-07-07
Abstract: An object pointer data structure for efficiently combining an object identifier and an object address for use in object-oriented programming systems.  An object address is a value that allows a client application or process to conduct high-performance operations on an object in the client's local virtual address space.  An object identifier is a value that can be used to uniquely identify an object for the lifetime of that object across some defined domain, such as an entire universe of computer systems.  The data structure of this invention defines an object pointer that is larger than the object address but smaller than the combination of the object identifier and object address. The truncated object pointer structure preserves all information from both object address and object identifier by forcing a portion of the local object address in each address space to be equal to a portion of the invariant object identifier.  A local pointer mapping table may be used for efficiency in assigning local addresses to restored objects in each process.

Abstract: Procédé et dispositif de mesure de la température et du niveau du bain d'électrolyse fondu, ou électrolyte, dans une cuve de production d'aluminium par électrolyse, selon le procédé Hall-Héroult, de l'alumine dissoute dans ledit électrolyte en contact avec les anodes carbonées et reposant sur la nappe de métal liquide formée sur le substrat cathodique et dont la surface au contact de l'air à la partie supérieure de la cuve est recouverte d'une croûte de bain solidifié, comportant l'immersion périodique dans l'électrolyte à une profondeur déterminée d'une sonde de température qui est retirée de l'électrolyte avant d'avoir atteint la température d'équilibre puis la détermination de cette température par extrapolation à partir des acquisitions intermédiaires de température à l'aide d'un programme de calcul préétabli. Parallèlement, on mesure le niveau de l'électrolyte HT dans la cuve à partir d'un point de cote de référence par enregistrement de la variation de potentiel entre le substrat cathodique et la sonde, dont la position est déterminée par un potentiomètre et dont le potentiel augmente brusquement lorsque l'extrémité inférieure de la sonde, ou pointerolle, entre en contact avec l'électrolyte. On détermine de façon similaire le niveau de métal HM à l'interface électrolyte/métal liquide d'où l'on déduit l'épaisseur de l'électrolyte HB = HT - HM.

Title: Plants having modified response to ethylene
Inventor: MEYEROWITZ ELLIOTT M
IPC: A01H5/00
Filed: 1994-06-30
Abstract: The invention includes transformed plants having at least one cell trans-formed with a modified ETR nucleic acid.  Such plants have a phenotype char-acterized by a decrease in the response of at least one transformed plant cell to ethylene as compared to a plant not containing the transformed plant cell. Tis-sue and/or temporal specificity for expression of the modified ETR nucleic acid is controlled by selecting appropriate expression regulation sequences to target the location and/or time of expression of the transformed nucleic acid.  The plants are made by transforming at least one plant cell with an appropriate modified ETR nucleic acid, regenerating plants from one or more of the transformed plant cells and selecting at least one plant having the desired phenotype.

Title: Dither signal remover for dithered ring laser gyro
Inventor: KILLPATRICK JOSEPH E
IPC: G01C19/66
Filed: 1994-09-30
Abstract: A sampling method and apparatus for sampling a dither signal (22) includes the step of sensing a number of peak amplitudes P1, P2, P3... Pn each of the number of peak amplitudes having corresponding times t1, t2, t3... tn while simultaneously sensing a number of ring laser gyro output angles at each of the corresponding times t1, t2, t3... tn. A value of the gyro net output, .DELTA., is calculated as .DELTA.=(n-n-1)-(.alpha.n-.alpha.n-1)K, where K is a correction factor. Alternatively, the stripped gyro angle output may be calculated as g=n-.alpha.nK. Where g is substantially equivalent to the sum of all of the changes in the stripped gyro angle, that is the sum of all .DELTA.'s. The correction may include corrections for gain, phase angle, nonlinearity, temperature bias and scale factors.

Filed: 1996-02-21
Abstract: A speech signal coding apparatus includes a dividing section for dividing a speech signal into units of sub-frames.  A spectrum parameter sectioncalculates a spectrum parameter for each sub-frame. An error signal generating section generates a perceptual  sensitivity   weighted  error signal from a reproduction signal and the speech signal for a sub-frame.  An adaptive code book is referred to based on the perceptual sensitivity weighted error signal sothat an adaptive code vector and a pitch period is selected.  Also, an excitation code book is referred to based on the perceptual sensitivity weighted error signal so that an excitation code vector is selected.  In a gain code vector section having a gain code book which stores gain code vectors, a gain code book is referred to based on the perceptual sensitivity weighted error signal, so that again code vector is selected.  Gains are determined from the selected gain code vector in units of time intervals shorter than the sub-frame, and a reproductionsignal is generated by weighting the adaptive code vector and excitation code vector with the determined gains within units of the time intervals.

Patent CA-2172642-A1 (CA)
Inventor: CANNIFF RONALD JAY
IPC: H04M1/65
Filed: 1996-03-26
Abstract: This tone detector which is suited for dual tone multifrequency (DTMF) digit detection, separates the pairs of tones into a low frequency and high frequency group in which the other frequency group is attenuated by filtering.  The amplitude of the low and high frequency groups serve as separate variable threshold reference signals.  Individual tones are bandpass filtered with their corresponding outputs converted into an amplitude signal.  The amplitude of the individually bandpass filtered tone signals are compared against the corresponding low or high frequency variable threshold signal for a determination of whether a tone is present. Preferably, additional validation steps are applied to the preliminary tone decisions to provide improved digit detection accuracy, especially in the presence of other signals such as speech.

Title: Illuminated vaginal speculum
Inventor: DICKIE ROBERT G
IPC: A61B1/32
Filed: 1994-11-10
Abstract: A single use, disposable, vaginal speculum uses a chemically fluorescent light tube (54) to provide built-in illumination for the body cavity being examined with the speculum. An integrally molded light tube holder has two opposing walls (50, 51) between which the light tube is inserted. Ridges (55, 56, 57, 58) on the inner surfaces of the opposing wails serve to guide the light tube into position in the speculum and to firmly grasp the light tube so as to prevent dislodgement during the examination. An integral stop member (53) is molded into the light tube holder to terminate the insertion of the light tube into the holder in precisely the position required to properly position the light tube.

Patent CA-2181882-A1 (CA)
Inventor: MUELLER JUERGEN
IPC: B66B5/14
Filed: 1996-07-23
Abstract: In this equipment for the production of the load in a lift cage (3), a motor (4) drives a drive pulley (5), over which a hoist cable (6) is guided. A carrying frame (7) is arranged at one end of the hoist cable (6) and a counterweight (8) is arranged at the other end of the hoist cable (6). The lift cage (3) rests on spring elements (9), which bear on the carrying frame (7). A belt (12), which is guided by way of a first deflecting roller (10) and a second deflecting roller (11), is coupled mechanically with the lift cage (3). The movement of the lift cage (3) is transmitted to the belt (12), which drives a pulse generator (13) coupled to the first deflecting roller (10).    In the case of changes in load, the spring elements (9) are compressed to a greater or lesser extent according to their characteristic, whereby the lift cage (3) moves relative to the carrying frame (7), which is in tum detected by the pulse generator (13) and translated into a travel signal (SL). From this, an evaluating unit (18) determines a load magnitude which influences a motor current (IW).
