Granted: 2005-02-22
Abstract: The supply circuit for discharge lamps (L) comprises an inverter (3) for generating a supply voltage at a specified switching frequency (f c) for a load circuit (15) comprising at least one lamp (L) and a resonant circuit (23, 25) in series with the electrodes (17, 19) of the said lamp. Associated with the load circuit is a control circuit (41) for turning off the supply to the load circuit in case of defective operation of the lamp (L). The control circuit (41) comprises a band-pass filter (35) centred on the switching frequency (f c) of the inverter and whose input signal is dependent on the voltage at a point (P) of the load circuit; the output signal from the filter is sent to control means (37, 39) associated with the said inverter (3) so as to turn off the supply to the load circuit in case of defective operation.
Patent CA-2247174-C (CA)

Abstract: A lock-up control device is provided to control engaging force of a lock-up clutch, which shares engine output with a torque converter to transmit it toward an input shaft of a transmission of a car. Now, target driving force is produced based on accelerator pedal opening and car velocity. Then, required torque is produced based on a gear ratio and the target driving force. Target engine speed is produced based on the required torque, wherein the target engine speed is set to avoid occurrence of abnormal sounds and abnormal vibrations. Thus, the lock-up clutch is controlled in such a way that real engine speed does not become lower than the target engine speed in case of a gear change corresponding to a shift-up operation, for example. Basically, the lock-up clutch is controlled to have engaging force, which is made as maximal as possible to improve fuel efficiency. In other words, the lock-up clutch is controlled to be as tightly as possible. Or, the lock-up clutch which is initially set at a tight state is turned off just after the gear change start timing if it is predicted that the real engine speed after the gear change will become lower than the target engine speed.

Title: Automatic call-work director
Inventor: BATTLE CALVIN W
IPC: H04Q3/64
Filed: 1997-08-04
Granted: 2003-05-13
Abstract: The capability of communications systems is improved in completing call requests by using automatic methods to enable a user of a call station withi n a cluster to be available to receive calls under terms that protect the user 's availability to do work other than answering calls. When a call is received (301), an assignment of a call station to handle the received call (301) is first attempted from among call stations associated with "first rights" interrupted clusters (302). If a call station in a "first rights" interrupte d cluster (302) is not available, an assignment is then attempted from among call stations associated with "rotating rights" interrupted clusters (303). If a call station in an interrupted cluster (302, 303) is not available, lists (304, 305) of available uninterrupted clusters are formed and used to determine an available call station, such that the received call (301) can b e forwarded to the available call station (306).

Abstract: Disclosed is an adjustable static umbrella with a static mast (2) to whi ch an arm (10) is secured by means of a hinge (12) allowing for the arm to be either adjusted into a use position or collapsed into a rest position and to be tipped about the hinge (12) tilting axle (14) perpendicular to the mast axis. The hinge (12) has a toggle head (80) and a pair of shells (82, 82') symmetrically inverted one to each other, encompassing the toggle head (80) therein and rotatably mounted about the tilting axle (14), while the pair of hinge shells (82, 82' ) is provided with a length guide perpendicular to the tilting axle (14), in whic h the arm (10) is inserted. A locking device (90) includes a tilting hinge (92) parallel to the tilting axle (14) and a fastening device (94) allowing for the hinge shells to be pressed one against the other and against the toggle head (80) so that , when said fastening device in the length guide (84) is pulled, the arm canno t be displaced, while the hinge shells (82, 82') encompassing the toggle head cannot be twisted due to pairs of interactive contact surfaces. Releasing the locki ng device (94) loosens the arm (10) length guide (84), thereby enabling adjustment of the arm, in the area of a tilt angle (.alpha.) limited by two end-stops (116, 116', 118, 120), between a rest position and a use position.

Granted: 2008-07-08
Abstract: An operative element mover (22) is used as a part of an ultrasound imaging or other catheter system (2) including a hollow sheath (6) and a case (16) housing a rotary driver (10). A drive cable or other connecting member (8) is disposed within the sheath with a transducer (24) at its distal end (26) and its proximal end (12) coupled to the rotary driver. The rotary driver rotates the transducer about the longitudinal axis (14) of the sheath. A hemostasis valve (50) anchors the sheath to the patient where the sheath enters the patient. The transducer mover (22) is used to move the drive cable along the longitudinal axis and includes a body (38) fixedly mountable to and dismountable from the case and a movable anchor post (40). The anchor post is clipped to the sheath and is moved by a sheath anchor drive (46) to translate the sheath from or toward the case. This causes the transducer to move within the sheath in a proximal or distal longitudinal direction (52).

Abstract: La présente invention concerne un essai et un nécessaire de détection de la résistance phénotypique d'un rétrovirus prélevé dans un échantillon biologique à un médicament inhibiteur de transcriptase inverse. Cet essai repose sur une analyse directe de la susceptibilité d'une transcriptase inverse rétrovirale à l'inhibition par un médicament inhibiteur de transcriptase inverse. L'activité enzymatique de la transcriptase inverse se calcule en mesurant le produit d'ADN obtenu lorsqu'on met à incuber une matrice d'ARN et une première amorce d'ADN complémentaire en provenance d'une région appropriée du génome du virus de l'encéphalomyocardite, l'incubation se faisant avec un échantillon biologique contenant une transcriptase inverse, et ce, en présence du médicament par rapport auquel on cherche à déterminer la résistance. Le mélange d'incubation est mis à réagir dans des conditions telles que la matrice d'ARN et l'amorce d'ADN donneront lieu à une renaturation d'acide nucléique et où le brin d'ADN se synthétisera sous forme d'une extension prenant sur l'amorce d'ADN si la transcriptase inverse de l'échantillon est résistante au médicament et n'est pas inhibée par le médicament. L'amplification du produit d'ADN se fait en utilisant, d'une part une seconde amorce d'ADN complémentaire provenant du génome du virus de l'encéphalomyocardite, et d'autre part des réactifs appropriés d'amplification en chaîne par polymérase, dans les conditions adéquates. La détection du produit amplifié se fait selon les procédés habituels bien connus des praticiens. La détection d'ADN amplifié constitue une indication de la résistance au médicament employé dans l'essai.
