Patent CA-2240850-A1 (CA)
Inventor: O'REGAN PATRICK J
IPC: A61B17/12
Filed: 1997-03-05
Abstract: An elastic band ligation device for treatment of hemorrhoids permits a doctor to band hemorrhoidal tissue without an assistant and does not have to be attached to an aspirator. The device has the capability of suctioning tissue into a tubular member before banding. A plastic inner tubular member retains a stretched elastic band over a front end of an inner tubular member which extends for a sufficient length for insertion into the rectum of a patient. A plunger in the tubular member may be slid backwards to draw a suction in the tubular member to draw tissue in through the front end. A plastic outer pusher sleeve fits over the tubular member and is adapted to push the elastic band off the front end of the tubular member to capture the hemorrhoidal tissue drawn into the tubular member.

Title: Means for and methods of real time detection of fraud, lack of credit, and the like, in the ss#7 system network
Inventor: KARRAS ERNEST
IPC: H04M7/06
Filed: 1998-06-18
Abstract: Service observing equipment monitors, detects, decodes correlates and generates Call Records and Report Summaries from digital and audio information on an individual call basis on either ANSI or CCITT Signaling System #7 systems controlled by data packets transmitted along high speed data links separated from the telecommunication audio channels. The equipment simultaneously responds to in-band signals such as Automatic Number Identification (ANI) digits and/or Customer Entered digits transmitted over the audio channels. A Call's decoded content is stored as correlated data until the end of a monitored call. Then the stored data is custom formatted into a Call Record and transmitted or printed out to enable study of how trouble free the telecommunication network is performing, detect fraud or credit violations and/or validate billing situations. An integral ZIP System simultaneously monitors the stored call data and is ready at all times during the call to generate interim ZIP Records to let the telephone system or recipient take corrective action while a call is in progress. Examples of such corrective actions are to trace the switching route and troubleshoot defective call setups before termination, to trap on Hot number, long-duration and/or duplicate credit card calls to prematurely terminate service and prevent fraud, to trace annoyance or malicious call and tape conversations, to eliminate abuse of pre-paid billing credit and the like.

Patent CA-2253642-A1 (CA)
Title: Cryptosporidium detection method
Inventor: ROCHELLE PAUL A
IPC: C12Q1/68
Filed: 1997-05-08
Abstract: The subject invention provides processes and kits for detecting encysted forms of protozoa, particularly Cryptosporidium and Giardia, that are viable and infectious. To determine viability, cysts or oocysts are heated to a temperature that induces transcription of heat shock protein (HSP) genes.  Alternatively, to determine infectivity the encysted forms are inoculated onto susceptible cell cultures. The viability or infectivity of the encysted forms can be determined by synthesizing a cDNA from an induced HSP RNA template using a primer that is specific for particular genus or species of protozoa, followed by enzymatic amplification of the cDNA. Alternatively, infectivity can be determined by amplifying HSP DNA from infected cells using a primer pair that is specific for a particular genus or species of protozoa. Amplified HSP DNA can be detected using probes that are specific for a protozoan species of interest, such as the human pathogens C. parvum and G. lamblia. Moreover, both Cryptosporidium and Giardia can be detected simultaneously by using two primer pairs in a multiplex amplification reaction.

Title: Safety apparatus for horizontal lifeline
Inventor: OSTROBROD MEYER
IPC: A62B35/04
Filed: 1998-12-15
Abstract: A safety apparatus is capable of tensioning a horizontal lifeline while providing an adjustable shock absorber and a gauge or indicator for indicating the amount of tension on the lifeline. A housing is adapted to be secured to an anchor point through an anchoring line. The free end of a horizontal lifeline passes over a pulley within the housing and around a number of rollers which are adapted to maintain the lifeline in secure contact with the pulley. A lever is utilized to rotate the pulley in order to tension the lifeline. The lever, however, is interconnected to the pulley through an adjustable disk brake which can be preset to a desired force. When the tension on the lifeline reaches its desired level, the brake slips and the lever can freely rotate. A second series of disk brakes connected to the pulley function as a shock absorber. In the event of a fall, the initial force on the horizontal lifeline exceeds the braking force of the shock absorber brakes and the pulley can rotate through a limited number of turns. Eventually, however, the shock absorber brake slows the fall and eventually stops the same. The amount of tension on the shock absorber brake can also be adjusted to thereby control the amount of shock being absorbed. An additional brake mechanism prevents the lifeline from freely being drawn from the housing in the event of a complete failure of the mechanism thereof.

Ce système illumine ou fait apparaître des pièces ou "trames" des représentations présentées dans le tunnel de telle manière que les passagers d'un véhicule en déplacement, tel une rame de métro, voient un effet d'animation apparent. Dans une des réalisations de ce système, des lumières stroboscopiques couplées aux rames ou sises dans le tunnel lui-même sont projetées de manière proportionnelle à la vitesse du véhicule afin d'illuminer par séquences des portions d'illustration fixes. Pour éviter une distorsion de l'image, deux circuits de commande séparés sont utilisés pour déclencher les impulsions stroboscopiques pour les portions d'illustration adjacentes. Ce système permet également de changer de représentation à distance, de manière à présenter différentes séquences. Dans une autre réalisation, un dispositif à défilement rotatif contenant des portions d'une pluralité de séquences de représentations différentes permet de sélectionner à distance les pièces à présenter. Dans une autre version, les images sont affichées électroniquement par un système de projection coulissant ou un écran plat DEL relié par câble ou par satellite à un terminal de télécommande pour le changement des affichages. Dans une des réalisation, une bande son accompagne l'affichage lors du passage de la rame. Lorsque les observateurs passent une certaine section de la représentation ils entendent une bande son associée à cette section particulière. Une autre version comporte des rangées successives de lumières DEL montées sur la surface de mur située en face de la rame, chaque lumière étant couplée à un système de commande actionnant la lumière pendant une période prescrite. La combinaison de flashs de lumière et du train en mouvement est utilisée pour présenter des messages ou des images aux spectateurs en transit.

Title: Method and apparatus for adapting non-cellular private radio systems to be compatible with cellular mobile phones
Inventor: HAARTSEN JACOBUS CORNELIS
IPC: H04W48/10
Filed: 1997-08-22
Abstract: The air interface of a private radio system (10) is adapted to be compatible with the air interface of a cellular mobile network (20). The private radio system's beacon channel (BCH) includes a dual-burst type of frequency correction channel (FCCH) and synchronization channel (SCH). The burst formats of these two channels (FB, SB) are defined according to the frequency correction channel and synchronization channel burst formats used in the cellular mobile network (20). An information message carried in the private synchronization channel (SCH) includes status and identity information related to the private radio system. An access request channel (ARCH) is defined for the private radio system, which enables a mobile terminal to request access to the private radio system. The protocol of the private radio system's access request channel (in the uplink) is similar to the protocol of the celular network's access grant channel (AGCH) used in the downlink. Alternatively, the protocol of the cellular network's synchronization channel (SCH) in the downlink can be used for the private radio system's access request channel (ARCH) (in the uplink). Consequently, the mobile terminal (26) can be used as a private cordless phone.

Title: Prestressed compressor mount installation apparatus and associated methods
Inventor: RASMUSSEN RONALD J
IPC: F16M5/00
Filed: 1999-03-04
Abstract: An elastomeric compressor mount has a hollow convex cylindrical head portion which must be passed upwardly through a substantially smaller diameter circular opening in a support foot portion of the compressor. To facilitate the passage of the mount head portion through the support foot opening a specially designed clamping tool is provided which has an arcuate support portion and a clamping portion that may be pivoted toward and away from a concave side surface of the support portion. With these two tool portions pivoted toward each other they are inserted downwardly through the compressor foot opening, opened, and then clamped exteriorly onto the mount head portion in a manner deforming it to a generally U-shaped configuration as viewed along the axis of the mount. The deformed mount head portion, and the still clamped together tool portions are then pulled upwardly through the compressor foot opening, the free ends of the deformed, generally U-shaped mount head portion being pushed toward one another by side edge portions of the foot opening as the head portion passes upwardly through the opening.      After the deformed mount head portion is positioned above the top side of the compressor foot, the tool is released to permit the mount head portion to spring back to its original annular configuration and overlie an annular top side surface portion of the compressor foot.

Title: Handover arrangement for mobile station moving across the boundary of wireless cell-site stations of adjacent pbxs
Inventor: ITAGAKI YOSHIO
IPC: H04M3/00
Filed: 1999-04-15
Abstract: In a PBX network, a global database is provided in each PBX node for storing shared data for verification of authorized mobile stations when accessing the network via a wireless cell-site station. During a wireless mode, a mobile station monitors the strength of its downlink signal from a first cell-site station of a first PBX node. If it falls below a threshold, the mobile station begins a scan across the spectrum. If a strong signal is detected, it stops the scan and transmits a handover request message to a second cell-site station transmitting that strong signal. The second node receives the message via the second cell-site station to establish the mobile's verification. If the mobile station is an authorized user, the second node transmits a handover grant message to the second cell-site station, transmits a command message to the first node for a switchover to a link between the first and second nodes, and connects the link to the second cell-site station.
