Title: Methods and apparatus for an electrode balloon
Inventor: MORNINGSTAR RANDY L
IPC: A61B18/16
Filed: 1999-02-17
Abstract: A flexible support (10) for a thin electrically conductive electrode (11) having an edge (16) around its major surfaces (13 and 14). One or more circumferential frames (15) on the support capture the edge (12) of the electrode (11) by an under cut (16) on the frame (15). A membrane (17) is integral with the one or more frames (15) to extend and be coextensive with each. The membrane (17) is thin to allow expansion in deference to each frame (15). The one or more frames (15) and the membrane (17) form a balloon (17) with interior and exterior surfaces (20 and 21) with an inflation port (22) therethrough. A method of making the support (10) for the electrode (11) has a mold cavity (30) to shape the support (10 on an unpolished surface finish to enhance release of the support (10).

Title: Full term development of animals from enucleated oocytes reconstituted with adult somatic cell nuclei
Inventor: YANAGIMACHI RYUZO
IPC: C12N5/10
Filed: 1999-01-20
Abstract: Animals are produced following injection of adult somatic cell nuclei into enucleated oocytes. The invention provides a method for cloning an animal by directly inserting at least a portion of an adult somatic cell nucleus into a recipient enucleated oocyte. Preferably, the nucleus is inserted by microinjection and, more preferably, by piezo electrically-actuated microinjection. The oocyte is activated prior to, during, or up to about 6 hours after insertion of the nucleus, by electroactivation or exposure to a chemical activating agent, such as Sr2+. The activated renucleated oocyte is allowed to develop into an embryo and is transplanted to a host surrogate mother to develop into a live offspring.

Title: Wheelchair and link assembly for use with a wheelchair
Inventor: FREUND EDWARD F
IPC: A61G5/10
Filed: 1999-02-22
Abstract: A wheelchair (10) includes side frame assemblies (12), seat frame bars (16), a cross-brace assembly (14), and link assemblies (44) for connecting the crossbrace assembly (14) to the side frame assemblies (12). The link assemblies (44) include an upper link assembly and lower link assembly attaching to each side frame assembly (12) and the cross-brace member (38). The link assemblies (44) enable the user to adjust the cross-brace member (38) relative to the side frame assemblies (12) at any one of a plurality of substantially horizontally spaced adjustment points (84). The adjustment points lack any substantial vertical adjustments. The horizontal points may be spaced a predetermined distance apart to enable a user to incrementally adjust the spacing between the side frame assemblies (12). Varying the spacing between the side frame assemblies (12) does not affect the height of the seat frame bars (16). The link assemblies (44) are interchangeable from one side frame assembly (12) to the other.

Inventor: BOULAY ANDRE ERIC
IPC: H04W4/02
Filed: 2000-09-19
Abstract: The present invention is an improvement over US patent no. 5.895.436 to Savoie et al. That patent discloses a vehicle tracking method and system using the cellular network infrastructure. A cellular transceiver is installed in a vehicle which requires tracking, and operates on a continuously stand-by mode, to remain accessible to the cellular security provider. The cellular transceiver is turned on to an active mode when tracking of the vehicle is initiated. The general location of the stolen vehicle can be determined by paging the cellular transceiver located in the stolen vehicle to identify one or more cell sites located near the stolen vehicle. The information is then relayed to a tracking vehicle which makes use of a radio direction finder to obtain an accurate bearing on the location of the stolen vehicle.     In another embodiment, the tracking vehicle which is provided with a radio direction finder can determine using a global positioning system receiver its location with respect to one or more cell sites identified as being close to the stolen vehicle such that the tracking vehicle can quickly travel to the area identified by the selected cell sites. One of the main issues of that patent is conserving the integrity and security of the on-board system. In fact, the on-board system must be hidden from view, so as to prevent a potential thief from disarming the system.      However, a problem with using such a system is that the cellular provider must, in order for the vehicle to be tracked, provide information relating to location of cell sites, and must also give access to other proprietary information.  Some cellular providers do not wish such information to be revealed. Furthermore, the

Title: Apparatus and methods for prediction of scour related information in soils
Inventor: BRIAUD JEAN-LOUIS
IPC: E02B3/00
Filed: 1999-03-12
Abstract: Methods are described for measurement and prediction of site specific scour around a structure obstructing a flow. Representative soil samples are collected from an area proximate the structure location and tests are conducted on the samples to determine the erosion rate and hydraulic shear stress imposed. The maximum shear stress and initial scour rates around the structure are also obtained. Next, the maximum depth of scour is calculated, and the depth of scour versus time curve for the structure is then predicted. In a preferred embodiment, the methods described are used to predict a scour depth versus time curve around a cylindrical bridge support standing in the way of a constant velocity flow and founded in a uniform cohesive soil. An erosion function apparatus is also described which can be used to test representative samples of soil in the area where a structure is located.
