IPC: B01D63/02
Filed: 1999-11-30
Abstract: An apparatus for carrying out liquid-liquid mi-cro extraction or liquid-liquid-liquid micro extraction with high enrichment comprises: a) a container for a sample solution having volume Vs with dissolved substance, analyte, to be analysed, b) a second con-tainer arranged in the first container, preferably a dis-posable container, having permeable membrane walls, for an acceptor solution, having volume Va, wherein 1) Vs:Va >= 50 and 2) about 1 µl <= Va <= 50 µl, c) stir-ring means, preferably a magnetic bar. The method is applicable for liquid-liquid micro extraction (LLME) and liquid-liquid-liquid micro extraction (LLLME) with high enrichment. In the latter case, a liquid im-miscible with the sample solution and the acceptor solution is immobilised in the wall of the container for the acceptor solution. There is also described a disposable device for use in liquid-liquid micro ex-traction in the form of a sponge body having defined pore volume for absorption of an immobilised accep-tor solution for an analyte from a volume of a sample solution.

IPC: A61F2/82
Filed: 2001-09-05
Abstract: A method and system for delivering a therapeutic agent directly to the heart employing minimally invasive techniques and concepts. In particular. the delivery of vascular endothelial growth factors (VEGF) is performed endovascularly or endoxopically to a region of a patient's heart treated with transmyocardial revascularization (TMR). A system is provided for inducing cardioplegic arrest. An aortic occlusion device has an inflatable balloon which occludes the ascending aorta when inflated.  Cardioplegic fluid may be infused through a lumen of the aortic occlusion device to stop the heart while the patient's circulatory system is supported on cardiopulmonary bypass_ A side-firing fiberoptic laser is introduced through the aortic occlusion device in the endovascular technique to perform TMR. Subsequently, a therapeutic agent delivery catheter is directed into one of the coronary arteries to deliver and dissipate the VEGF      into the surrounding vascular plexus to promote angiogenesis stimulation. Alternatively, a therapeutic agent delivery material saturated or coated with VEGF could be sutured to the epicardial surface of the heart, using thoracoxopic techniques. ~~~~~ ~~~~~  ~~~~~ ~~~~~                 TMR treated site.

IPC: H04B7/185
Filed: 2001-12-14
Abstract: An efficient method for providing both dedicated and simulcast services over a common wireless infrastructure is described. The services can be available to a single terminal as well as to a multiplicity of terminals simultaneously. The method uses time division multiplexing and orthogonal frequency division multiple access for simulcasting information and transmitting dedicated message information from a plurality of base stations forming a cellular pattern over the same wireless frequency channel. The method comprises the steps of constructing frames for transmission by the plurality of base stations comprising control information, simulcast information and dedicated message information within predetermined time slots of the frames and allocating the simulcast information and the dedicated message information to time slots of the same frame predetermined by the control information of the frame. The underlying modulation technology used is OFDM and thereby the channel delay-dispersion is minimized.

The method also includes the step of determining a first group (g1) of beams which covers the first location of the UT at a second time t2, where g1 <  n and time t2 is later in time than time t1. A page is then sent from the gateway to the UT on a channel, such as a paging channel, of at least one beam of the first group of beams. In one embodiment, the page is sent on the paging channel of each of the first group of beams.

Title: Motor-operated jack for vehicles
Inventor: SHIM JONG-UK
IPC: B66F3/10
Filed: 2002-05-13
Abstract: A motor-operated jack for vehicles is disclosed. In the motor-operated jack of this invention, a lifting unit consists of a spiral lifting ram having an internal thread limitedly formed at a lower portion of the spiral lifting ram, thus reducing its frictional resistance. A pin is held in a horizontal groove formed at the tap end of a primary screw. This pin is slightly projected into two longitudinal holes symmetrically formed at the top portion of a secondary screw. A coil spring, a spring cover and a snap ring are sequentially laid on the top of the pin such that the snap ring is seated in an annular groove formed on the inner surface of the top wall of the secondary screw, thus allowing the coil spring to bias the pin. This second screw is thus prevented from being raised along with the spiral lifting ram. A support ram, having a top support and an external thread, is movably fitted in a gap between the secondary screw and the spiral lifting ram while engaging with an internal thread of the spiral lifting ram at the external thread, thus allowing a user to control the moving stroke of the lifting unit as desired.
