Title: Hemostasis cannula
Inventor: OSBORNE THOMAS A
IPC: A61M25/01
Filed: 1996-10-24
Granted: 2007-03-13
Abstract: This invention is a hemostasis cannula comprising a housing (10) having a passage (11) therethrough size to receive a catheter (57), and a valve body (1) (1') (1") mounted in the passage (11). The valve body (1) (1') (1") includes an opening (2) (3) (102) (103) (112) (113) (2') (3') (2") (3") therethrough which forms a seal around a catheter (57) enclosed within the cannula. In one embodiment, an internal ring (8") of pliable material lines at least a portion of the interior of the opening (3 '). The valve body (1) (1') (1") is compressed within the cannula housing (10). When the catheter (57) is removed, the valve body (1) (1') (1") closes thus blocking airflow into the patient's blo od vessel and also blocking blood flow out of the patient's blood vessel. The cannula housing (10) also includes a side port (45) for introducing fluids into the patient's blood vessel.

Abstract: An AC-DC power supply system for receiving a three phase mains supply and outputting a transformed DC supply. The power supply unit has a rectifier circuit (30) providing an output to a three phase inverter circuit (40) to generate a pseudo AC three phase output of higher frequency than the AC supplied to the rectifier circuit (30). A  three phase transformer (60) receives the pseudo AC three phase output and transforms the output to a three phase rectifier circuit (70) to generate the output DC supply. The inverter circuit (40) provides a three leg bridge structure with each leg having a switching device one of which is used to provide a phase reference whereas the other two legs control the relative phase shift on each leg to reduce the phase shift relative to the phase reference on one leg and increase the phase shift relative to the phase reference on the other leg.

Abstract: A technique and apparatus for developing AGC voltage in a receiver capable of receiving VSB signals that do not have the average magnitudes of the data symbol levels and the sync symbol levels related so as to produce the same average level. One technique eliminates the sync symbols from determination of the AGC voltage. A preferred technique corrects for the different symbol levels (56, 58 and 60) of the sync by multiplexing (54) in an offset at the proper time or multiplying the sync symbols by a compensating factor.

Abstract: A dielectric filter includes electrodes formed on both principal surfaces of a dielectric substrate wherein each electrode has a plurality of openings which are formed so that the locations of the plurality of openings formed in one electrode disposed on one principal surface of the dielectric substrate correspond to the locations of the openings formed in the other electrode disposed on the other principal surface of the dielectric substrate.  The dielectric substrate is disposed between upper and lower conductive cases.  A non-electrode coupling part is formed between openings thereby coupling resonators with each other or coupling a resonator with input/output means.  Thus, the invention provides a resonator which can be easily coupled to another resonator or input/output means and also provides a filter having a wide-band characteristic.

Title: Method for indicating that a text message is present in a message central module of a mobile radiotelephone network
Inventor: SCOTTO DI CARLO VINCENZO
IPC: H04L12/54
Filed: 1997-09-29
Granted: 2006-11-07
Abstract: The invention concerns a method for indicating the availability of a text message in a mobile radiotelephone network (PLMN) when the recipient is registered as a subscriber both in a mobile radiotelephone network (PLMN) and in another telecommunications network (PISN).   According to the invention, the accessibility of the subscriber in the other telecommunications network (PISN) is stored in the data base allocated to the subscriber in the mobile radiotelephone network (PLMN). The central messaging module (NZM) transmits a notice on the availability of a text message for the subscriber to a control module (SM) of the other telecommunications network (PISN). This control module (SM) displays then an information on a terminal (KE2) allocated to the subscriber in the other telecommunications network (PISN) indicating the availability of a text message in the central messaging module (NZM) of the mobile radiotelephone network (PLMN).

Abstract: A fault indicator contained within a protective equipment closure of the type used to house pad-mounted components of a power distribution system detects the occurrence of a fault current in a monitored conductor and provides a light indication thereof. The fault indicator includes a circuit monitoring module, having an integral fault indicator flag module, and a remote fault indicator light module. A status-indicating flag is rotatably mounted in the integral fault indicator flag module. The flag is positioned in either a reset indicating position or a fault indicating position by a magnetic pole piece, which is magnetized in one magnetic direction or the other by momentary application of a current in one direction or the other to an actuator winding on the pole piece. A magnetically actuated reed switch in an auxiliary magnetic circuit comprising an auxiliary pole piece magnetized by the actuator winding and a bias magnet magnetically aligned to oppose the reset magnetic orientation and reenforce the trip magnetic orientation of the magnetic pole piece closes upon occurrence of the fault current to connect an internal battery to an LED contained within the remote fault indicator light module so that the LED is visible from the exterior of the protective equipment enclosure. The light indication of the fault occurrence may be reset automatically by a timed reset circuit, which includes a timing capacitor, or manually by a manual reset circuit, which includes a magnetically actuated switch housed in the remote light module and connected across the timing capacitor.

Title: Headland stop for agricultural planter
Inventor: HUNDEBY DAVID R
IPC: A01B73/00
Filed: 1999-11-10
Granted: 2008-10-28
Abstract: An agricultural planter is provided with hydraulically operated devices to effect the folding and unfolding of the planter support structure between operative and transport configurations. The planter includes a laterally extending tool bar that is pivoted about a transverse axis to forwardly roll the tool bar between a lowered field operating position and a raised transport position. The transverse pivot axis is located such that the first component of the pivotal movement of the tool bar from the field operating position is generally vertical, while a second component of the pivotal movement of the tool bar approaching the transport position is generally horizontal and forwardly of the first component. The headland position corresponds to a position in which the tool bar is raised sufficiently to move the planting units mounted thereon out of the ground to facilitate the turning of the implement at the end of the field. A sensor senses the positioning of the tool bar at the headland position and activates a valve in the hydraulic circuit to stop the operation of the tool bar actuators pivotally rotating the tool bar. A bypass, in the form of a solenoid that when selectively energized will override the signal of the sensor, selectively permits the tool bar to be raised the entire way to the transport position.

Title: Method and system for determining position of a cellular mobile terminal
Inventor: LUNDQVIST PATRIK
IPC: H04B7/26
Filed: 1998-09-11
Granted: 2008-08-19
Abstract: A method and system are disclosed by which a round--trip calculation is used to determine the distance between a mobile radio station (MS) and a radio base station (BS) using the apparent uplink and downlink signal propagation air-times (e.g., T-up and T-down). As such, no absolute time reference is required. The MS and BS report to a service node in the mobile network the local departure and arrival times of the uplink and downlink signals, and calculate the apparent air-times, T-up and T-down. The distance, D, between the MS and BS can be calculated as D = c(T-up + T-down)/2, where "c" equals the speed of light. The distances, D1, D2 and D3, to at least three base stations whose locations are known, can be used in a triangulation algorithm to determine the MS's position.
