Patent CA-2190940-A1 (CA)
Title: Radio range finder
Inventor: COVELEY MICHAEL
IPC: G01S13/84
Filed: 1995-05-31
Abstract: A radio range finding system (10) includes a radio range finder (12) and a plurality of remote mobile transponders (14). The radio range finder (12) transmits a signal modulated with an address code identifying a particular mobile transponder. When a mobile transponder receives the modulated signal (Ms) transmitted by the radio range finder and the modulated signal has been modulated with an address code that corresponds to the address assigned to that mobile transponder, the mobile transponder transponds a return signal (Rs) to the radio range finder. A receiver (32) in the radio range finder conveys the received signal to a mixer (30) which also receives an internal carrier signal identical to the modulated signal output by transmitter (20).  The output of the mixer is then filtered and demodulated to yield an output signal proportional to the distance between the mobile transponder (14) and the radio range finder (12).

Title: Hydraulic disconnection device
Inventor: BAKKE STIG
IPC: E21B17/06
Filed: 1995-06-01
Abstract: A hydraulically or pneumatically releasable disconnecting device (1), through which a liquid can flow, and wherein two end pieces (2,3) are connected in that an expandable lacking ring (20) in normal position engages grooves (23) in a locking sleeve (10). An axially displaceable locking sleeve (6) surrounds the locking ring (20) with one end thereof and prevents the locking ring (20) from expanding and disengage the grooves (23). The locking sleeve (6) is fixed with shear pins (7). When the disconnecting device (1) is to be released, a sealing body (14) is placed in a seat (13) in a piston sleeve (12), preventing flow of liquid therethrough. Hydraulic force acting against the sealing body (14) and the piston sleeve (12), urges the piston sleeve (12) against the safety sleeve (6) such that the shear pins (7) are broken, Thus, the safety sleeve (6) is displaced such that it can no longer surround the locking ring (20). The grooves (23) are provided with inclined flanks, and the axial force against the locking ring (20) gives a resultant radial force causing the locking ring (20) to expand and disengage the grooves (23) in the lacking sleeve (10).

Title: Draw tape machines and methods
Inventor: SELLE PAUL A
IPC: B31B19/90
Filed: 1996-12-11
Abstract: This invention pertains to draw tape equipment, and methods for incorporating draw tapes into plastic and like bags. In general, a continuous plastic web is slit at a slitting station to form layers, and respective free edges. The web then passes to a hole forming station where holes are formed in the top and bottom layers adjacent the free edges. After holes are punched, edge regions of the top and bottom layers are separated from each other, followed by forming of hems in the separated layers at hem forming stations arranged in parallel with each other. Concurrent with forming of the hems, continuous draw tapes are fed to the hem forming stations and the hems are formed about the draw tapes. The formed hems, with the draw tapes incorporated therein, optionally pass through transverse stretching apparatus and/or through electrostatic pinning apparatus and/or through first temperature control stations where the temperature of the plastic web is controlled to a desired temperature before hem sealing. The formed hems are then sealed to the main bodies of the respective top and bottom layers. The sealed hems optionally pass through second temperature control stations to cool the web. The edge regions of the layers are then rejoined, in face-to-face relationship with each other.

Abstract: On propose une méthode et un système permettant de déterminer un débit de transmission réel d'une communication codée transmise à un débit parmi une pluralité de débits de transmission. Une communication codée est décodée à la pluralité de débits de transmission pour générer des signaux décodés et des paramètres de décodage qui indiquent la fiabilité des signaux décodés. Un ou plusieurs débits de transmission candidats sont identifiés en fonction desdits paramètres de fiabilité de décodage. S'il existe seulement un débit de transmission candidat, le débit de transmission réel est défini comme ce débit de transmission candidat. S'il existe plus d'un débit de transmission candidat, les signaux décodés sont de nouveau codés aux débits de transmission candidats auxquels ils ont été décodés. Les bits de la communication sont alors comparés avec les bits des signaux de nouveau codés pour chaque débit de transmission candidat afin de déterminer le débit de transmission réel. On présente en outre une méthode et un système permettant de déterminer des valeurs de seuil à comparer avec les paramètres de fiabilité de décodage, afin d'identifier les débits de transmission candidats. On présente en outre une méthode et un système qui déterminent ces valeurs de seuil en fonction de conditions de réception détectées, notamment l'intensité relative des signaux de composant multivoie et la puissance de réception totale dans la communication.

Abstract: The invention relates to a method and an apparatus for creating facial images, more particularly to a composite picture system and method utilising a library of basic facial components. In typical composite picture systems, the process of creating facial images includes the steps of selecting various facial components, herein designated as basic morphological elements, from a library and assembling them. The novel method comprises the introduction of a component calibration step allowing the different basic morphological elements of a facial image to be merged into a single synthetic facial image with proportional components. A universal skin tone, created using a set of filters on the original images, is also used. to reduce the contrasts between the individual basic morphological elements. In addition, each basic morphological element is encoded and uniquely describes each facial image. The use of the encoding facilitates the transmission of such images requiring only the code to be sent. The invention further provides a computer readable medium comprising a library of basic morphological elements and a program element that direct a computer to implement the composite picture process.
