Filed: 1993-09-17
Granted: 1999-12-14
Abstract: A teat unit for use for a disposable package comprising an upwardly extending teat part, and intermediate cover plate and a downwardly extending insertion part. The cover plate has the same extent as the area of the package side on which the teat unit is placed, and the insertion part is provided with holding means, adapted to hold the opening rim in direct sealing engagement at the downwardly facing side of the cover plate. This provides a teat unit which ensures that a baby's mouth will not contact said package side which may be contaminated by bacteria.
Patent CA-2172011-C (CA)
Title: Subtitle encoding/decoding method and apparatus
Inventor: TSUKAGOSHI IKUO
IPC: H04N19/152
Filed: 1996-03-18
Granted: 2006-02-07
Abstract: Encoding and decoding of subtitle data is performed in real time. A buffer regulates a flow rate of the subtitle data to ensure that the appropriate subtitles are superimposed with the correct video picture. In encoding, subtitles are generated in correspondence to a video picture. The subtitles are separately encoded and multiplexed with the video picture for transmission. Upon decoding, the subtitles are selected at a time which corresponds to the display of the corresponding video picture. Since the subtitles are processed separately from the video data, the subtitles may be manipulated with great control; thus providing more flexibility in encoding and decoding.

Title: Hand and arm strength testing apparatus to be used in a constable selection process
Inventor: GLEDHILL NORM
IPC: A61B5/16
Filed: 1996-09-27
Granted: 1999-11-30
Abstract: A hand grip and arm strength testing apparatus is used as part of a pursuit and restraint circuit in a constable selection process.  The apparatus which simulates the action required to move an uncooperative individual's arms to a handcuffing position comprises a support structure with a pair of moveable arms each of which is biased to a widespread position relative to the other arm. Each of the arms has a handle with a lock which is biased to a locking position and which locks against movement of the arm on which the handle is provided.  The lock is moveable to an unlocking position by hand grip pressure sufficient to overcome the bias on the handle lock whereby the arm is then swingable inwardly from its widespread position when sufficient arm strength is applied to, and overcomes, the bias on the arm.

Granted: 2001-09-11
Abstract: La présente invention permet d'évaluer et de commander avec précision la fonction de transfert système d'un système imageur (408) en procédant par élimination des interférences imputables aux composantes pseudonymes. La saisie de l'image se fait au moyen d'une primitive d'image (406) caractérisée par une structure à un seul axe orientée selon un angle spécifique (701, 702) par rapport aux axes primaires d'une structure d'échantillonnage. Pour évaluer avec précision la fonction de transfert système, le procédé consiste à calculer (53) une représentation des fréquences en deux dimensions. Le procédé consiste ensuite, grâce à une transposition de fréquence (53) le long de l'axe perpendiculaire à l'axe de la primitive d'image (406), à faire une séparation entre d'une part les composantes de la représentation pour lesquelles il existe des composantes pseudonymes et d'autre part les composantes de la représentation pour lesquelles il n'existe pas de composante pseudonyme. Cette évaluation précise de la fonction (58) de transfert système rend possible une commande précise de la fonction de transfert système.

Granted: 2001-10-30
Abstract: A method and apparatus for processing dropped  calls. If. during an established call between two communication devices, a telecommunication network node determines that a communication link to one of the devices has been dropped, the node determines the cause of the dropped communication link and sends a status message to the non-dropped communication device. If a reconnection attempt is appropriate, the node attempts to reconnect to the dropped device. If a reconnection  is not appropriate, or if the reconnection attempt is unsuccessful, the non-dropped communication device is connected to a voice mail node. If the reconnection attempt is successful, the call between the two communication devices is re-established.

Title: Dual valve fitting for enabling quick measurement of pressure
Inventor: LI WEI
IPC: F16L37/28
Filed: 1998-03-26
Granted: 2004-06-22
Abstract: A dual valve fitting enables quick measurement of pressure contained within a housing. The fitting includes a valve body, a valve retainer, first and second sealing rings and a biasing mechanism. The valve body defines a flow passage within which is situated the valve retainer. The valve body is designed at its protuberant end to mate with a female coupler of a quick connect device and at its threaded end to screw into a threaded bore of the housing. The valve retainer defines around itself first and second annular recesses each of which spaced apart from the other to match the spacing of outer and inner annular valve seats formed in the flow passage. Forming a first valve, the first sealing ring retains in the first annular recess so as to be seatable against the outer valve seat. Forming a second valve, the second sealing ring retains in the second annular recess so as to be seatable against the inner valve seat. The valve retainer is biased within the flow passage so that the first and second sealing rings seat against the outer and inner valve seats, respectively, thereby rendering the first and second valves normally closed. Mating the female coupler to the protuberant end of the fitting causes the valve retainer to move inwardly against the biasing mechanism so as to open both the first and second valves thereby allowing flow from the housing through the flow passage and into the female coupler.
