Inventor: PERRY DEREK I
IPC: A01K23/00
Filed: 1999-08-04
Abstract: This device is a tool for collecting, bagging and easy disposal of canine and feline faeces in the garden, on walks, in the house or other buildings. It has a broomlike handle, a wire ring at the lower end for holding open a plastic bags, which has a string tied neck, the string being held temporarily by a clip on the handle.   The user secures the bag on the wire ring by first putting the bag in the centre of the ring, then wrapping the string threaded neck of the bag over and under the ring, pulling the string lightly so that the bag is held on the ring, then hooking the string on the handle's hook. When required the user places the bag at the end of the device under the defecating animal, when the animal has finished, the operator removes the string from the clip on the handle and tightens the neck of the bag, by pulling the string away from the handle and out beyond the wire ring, thus closing the neck of the bag with the waste matter in it, simultaneously freeing the bag from the ring Alternatively if not with the animal at the time of defecation the operator may, with a quick scooping action, lift the faeces from the ground or floor into the bag.  Removal of the bags proceeds in the same manner as in the paragraph last above.   The object then, in either case, is to remove the waste in an appropriate manner to a disposal system, and to re-fit the wire ring with another bag.

Title: Database access system
Inventor: CSASZAR ANDRAS
IPC: G06F21/84
Filed: 1998-04-21
Abstract: A system for organizing access to a database that is distributed over an electronic network includes a system site on a dedicated server. A list of addresses to approved database sites on an electronic network stored on the system site is accessed by a user with a browser application. Reference cards permit the user to search and review the list of approved sites. In a first preferred embodiment, a request for access to a database site is made to the dedicated server. Access is denied for a non-approved site. An approved database is retrieved by the dedicated server. Each database link to an approved site is modified from direct to indirect to require all future access to be directed through the dedicated server. Links not in the list of approved sites will have their access denied. In a second, equally preferred embodiment, code defining a database location is removed at the dedicated server to de-activate links to non-approved database sites. The words representing the de-activated links are bleached of any indicia that represent the previous electronic network link. In a third embodiment of the invention, a framed screen display overrides the browser application display to prevent a user from defining a location for independent access to the electronic network. The only access to the electronic network is provided through the dedicated server and the user is thereby restricted to accessing the approved sites.

Title: High-performance electro-optic intensity modulator using polymeric waveguides and grating modulation
Inventor: SUN DE-GUI
IPC: G02F1/065
Filed: 2000-03-02
Abstract: A high-performance electro-optic intensity modulator using two polymeric waveguides having a high extinction-ratio modulation process is implemented by the coupling-out effect of induced grating modulation. The two waveguides can be either single-mode or multi-mode, even highly multimode. The inducing of a modulated grating-coupler in a waveguide channel makes the coupling between two waveguides become unidirectional and the coupling efficiency can be achieved to a very high value in theory. The two waveguide channels in this intensity modulator may have large dimensions, so the device can support either single-mod or multi-mode operation. The electro-optic waveguide intensity modulator may be used either as a single optical modulator/switch or as a waveguide modulator/switch array for fiber-optic communication.

Title: Support arm
Inventor: HANSEN HENNING
IPC: B08B15/00
Filed: 1998-09-02
Abstract: A support arm has a support structure and an arm structure connected to the support structure through a pivotal connection for pivoting about a horizontal axis. A device is provided for adjusting the elevation of the arm structure by pivoting it about the horizontal axis. A  support base is connected to the arm structure through a pivotal connection for pivoting relative to the arm structure about an axis that is parallel to the horizontal axis. A support member is connected to the support base through a pivotal connection for pivoting about a vertical pivot axis, and auxiliary structure such as an air extraction arm may be connected to the support member. A linkage between the support base and the support structure maintains the pivot axis of the support base parallel to a vertical axis as the elevation of the ann structure is adjusted, and avoids the auxiliary structure from swinging under the influence of gravity to a neutral position different from that desired by an operator.

Patent CA-2321304-A1 (CA)
Inventor: CARLSSON GORAN
IPC: H04W36/30
Filed: 1999-02-12
Abstract: A method and apparatus for providing continuous verification of a mobile station for handoff operations in a cellular telecommunication system is described. In an embodiment of the present invention, a mobile station (MS) has an established wireless connection with a first base station (BS1). A  second base station (BS2) receives the uplink transmissions sent to BS1 from the MS as soon as it comes into receiving range. BS2 immediately initiates a verification procedure on the MS to determine whether a satisfactory connection can be made. The verification step is initiated by the second base station before a handoff procedure is initiated thereby reducing the amount of signaling between the MSC and associated base stations. Since the verification is initiated earlier, it occurs over a relatively longer period of time resulting in improved handoff reliability.
