Patent CA-2102108-A1 (CA)
Inventor: LAROSA CHRISTOPHER P
IPC: H03D3/00
Filed: 1993-01-21
Abstract: La présente description comporte un exposé sur un procédé de compensation de la distorsion de phase d'un signal reçu. Cette distorsion provient des caractéristiques asymétriques du limiteur de tension (301). La compensation permet d'échantillonner le signal reçu (115) aux croisements du zéro positif et négatif, ce qui réduit le recours à un oscillateur local dans un système de radiotéléphone. On échantillonne en premier lieu la phase du signal reçu aux croisements du zéro positif et négatif, ce qui fournit une valeur de phase correspondante de croisement positif (401) et de croisement négatif (407) concernant le signal reçu. On combine en deuxième lieu ces valeurs de phase de croisement positif et de croisement négatif pour engendrer un premier signal de différence (409). En troisième lieu, on engendre un signal d'erreur estimé (417) en utilisant le premier signal de différence. En quatrième lieu, on combine (419) le signal d'erreur estimé avec les signaux de phase des croisements du zéro positif et négatif pour éliminer en pratique la distorsion asymétrique.

Filed: 1992-07-28
Abstract: A system for reducing periodic noise, which includes a plurality of harmonically related noise signals, comprises an actua-tor (1) for producing a cancelling acoustic signal, a sensor (3) for detecting a residual noise signal, synchronizing signal generat-ing means (7) and processing circuitry (4-1, ... 4-n, 5, 6). The processing circuitry comprises a plurality of tunable harmonically related band pass filters (4-1, ... 4-n), a tuning signal generator (6) and a summer (5) which sums the outputs of the filters (4-1, ... 4-n). The tuning signal generator (b) receives the synchronizing signal from the synchronizing signal generating means (7) and outputs the tuning signals to the band pass filters (4-1, ... 4-n). As the frequency of the synchronizing signal changes, the tuning signal generating means (6) causes the tunable filters (4-1, ... 4-n) to track harmonics of the noise to be cancelled. After summing by the summer (5) and suitable amplification, the outputs from the filters (4-1, ... 4-n) are used to drive the actuator (1) so as to reduce the residual noise detected by the sensor (3). In one embodiment the filters (4-1, ..., 4-n) are implemented by means of switched capacitor filters.

Title: Screw cap for sealing a bottle or the like
Inventor: HERTRAMPF MICHAEL
IPC: B65D41/04
Filed: 1992-06-25
Abstract: A screw cap for sealing a bottleneck or the like with a substantially cylindrical securing section (1) with a female thread (2) which can be screwed on a male thread (7) of a bottleneck (8). The base of the screw cap forms a sealing section (3). In addition, there is a stop to define the posi-tion at which an edge of the bottleneck bears on the securing section. This stop is on the inner wall of the cylindrical securing section and preferably forms a bearing surface (6) in a plane perpendicular to the screw axis. As the bearing surface is on the outside of the bottleneck, the face of the bot-tleneck is free for the abutment of the sealing section or a seal. The stop se-curely establishes a given screw-on distance even when the cap is detached and refitted several times with differing torques and thus ensures that the force with which the sealing section or seal bears on the face of the bottleneck is precisely defined. This also precisely defines the pressure which, when exceeded, results in an increased internal pressure escaping from the bottle.

Title: A method of forming a dental prothesis for mounting in an implant, a method of forming a dental model for use therein, a dental formation mounting arrangement and a range of dental prosthesis mounting cores
Inventor: ASHER GEORGE B
IPC: A61C13/00
Filed: 1993-04-15
Abstract: An arrangement usable as a core for a dental prosthesis or as a transfer jig in forming a model of an alveolar arch with one or more implants (24), comprising a nut (36) which is for fitting in a hexagonal portion of a socket (30) in the implant (24), a ring (35) for fitting over the nut (36) and seating around the mouth of the socket (30), and a post (37) for screwing through the nut (36) and the ring (35) to the implant (24). The ring (35) also has a hexonal bore portion which receives part of the nut (36). Thus the ring (35) is located spatially and angularly relative to the implant (24) without being socketted therein. When a dental impression has been formed with a plurality of the rings (35) embedded therein, or when a subframe for a bridge has been made up on two or more such rings (35) on a model of the alveolar arch made from that impression, it is removed dry first unscrewing the post (37) and withdrawing it and the nut (36). Thus the impression or bridge sub-frame is easily removed despite the probability that the axes of the implants (24) in the alveolar arch are not parallel.

Title: Dual stage rssi handoff trigger
Inventor: WILLHOFF STEVEN J
IPC: H04B17/00
Filed: 1994-03-16
Abstract: An appropriate handoff trigger is determined in a cellular system by maintaining both a long term representation of the received signal strength and a short term measurement of the current signal strength.      The long term representation is used as the initial trigger for a handoff condition. The averaging process removes the effects of short term fades in the signal that may cause a premature handoff decision due to these fluctuations. This initial trigger is then qualified by examining the short term current, value of the signal. The actual handoff trigger is only realized when both values indicate that the handoff threshold has been exceeded. This approach eliminates the occurrence of false handoff triggers caused by the historical bias that may exist from the long term averaging process. The short term signal strengths value is reported as the mobile station's signal for comparisons to the signal strength measured on the adjacent cells. Since this value represents the current measure of the signal, it provides a truer comparison with the current measurements made on the adjacent cells, and virtually eliminates delayed handoff realizations due to the long term average historical bias.

Title: Self propelled apparatus for refilling and compacting ground trenches
Inventor: BARLOW JOHN R
IPC: E02D17/12
Filed: 1994-05-16
Abstract: Refilling and compacting ground trenches dug for the purpose of laying utility lines and the like is often a time consuming job demanding the use of heavy equipment better employed in more productive activities and, of course, the time and cost of a relatively high skilled operator. In addition, the job is often complicated by lack of maneuvering room for such equipment. The present specification discloses a self propelled apparatus which is particularly well adapted for this refilling and compacting such trenches, the apparatus comprising a generally rectangular rigid frame having a pair of elongate side members, the side members incorporating ground en-gaging wheels at each end of each respective side member. At least one pair of axially aligned wheels are driven by conventional hydraulic motors. The center portion of the frame incorpo-rates a substantially centrally located cavity within which cavity is a bored pedestal mounted ring gear. A man sized cab having a pivot mounted to its underside for rotatable engagement within the bore of the pedestal is mounted upon the upper surface of the frame and is free to rotate through 360 degrees upon the frame. The cab further includes a hydraulic motor and pinion gear mounted to the cab's undersurface such that the pinion gear engages the pedestal ring gear. When activated, the cab motor drives the pinion gear which "walks" around the ring gear forcing the cab to rotate about the frame. A conventional vibratory compactor head is mounted to the front of the cab in the vertical plane and is operable both upwards and downwards in the vertical plane by the actions of a hydraulic ram. An internal combustion engine is mounted to the rear of the cab and rotates about the frame in unison with the cab. The engine provides power for the on-board hydraulic and electrical systems. Scraping blades are affixed to each end of each of the frame side members so that, as the frame move along over a centrally aligned trench, the earth piled to either side of the trench is forced into the trench. The compactor head follows behind the blades and compacts the fill into the trench. The cab may be rotated through a full 360 degrees to retrace the first pass over the trench without the need to move the frame off the trench, thus eliminating the need for a relatively large maneuvering space typically required when conventional equip-ment is utilized.

Abstract: In order to obtain an index which generally shows the work burden extent of various works carried out in an automobile assembling factory or the like, for each work content, the maximum muscle contraction ratio is measured after the work has been continued for 5 seconds, the work burden index (L) is calculated from the measured ratio value, and the equivalent work burden in a standard work is calculated from the calculated work burden index (L) for 5 seconds. The work burden index (TVAL) of actual work is calculated from the equivalent work burden and the actual work time. Suitably, a work routine plan is corrected such that the obtained TVAL is normalized with an apparatus comprising means for storing the equivalent work burden for each work content, means for displaying an image of the work content, and means for inputting work content parameter and so forth while watching the displayed image.

Abstract: POINTING DEVICE WITH IMPROVED PIVOT              Abstract of the Disclosure A pivotable trackball-type computer command pointing device for entering commands into a computer has a housing and a ball retained within the housing for generating electrical signals translatable into commands for the computer. A coupling assembly removably attaches to the computer, preferably the keyboard. A knuckle joint assembly pivotally connects the housing to the coupling assembly and includes a pivot blade pivotally received in an elongated recess of a hinge pocket plate to define an axis of rotation within the housing about which the housing is rotatable. Opposing button members each carry actuation teeth which engage a corresponding row of teeth formed in a coupling frame held stationary with respect to the computer by the coupling assembly. When the button members are moved together, the actuation teeth disengage the rows of teeth to permit the housing to be selectively angularly oriented by the user. Alternatively, pawls and corresponding ratchet teeth are used to provide unidirectional orientation of the housing upon depressing one of the two button members. In another alternative embodiment, a brake member having a high coefficient of friction is used to provide a brake to engage the coupling frame. Cams selectively force the brake member against an underside of the coupling frame to lock the housing into a selected angular orientation.
