Title: Toilet paper roll dispenser
Inventor: HOO KONG MICHELE RENEE
IPC: A47K10/38
Filed: 2001-05-24
Abstract: A dispenser for toilet paper rolls each having a hollow tube core section on which paper is rolled, comprises an upstanding elongated container defined by a peripheral wall and a base portion at a bottom end thereof. A removable cover portion is at an open top end of the elongated container. The peripheral wall has an aperture defined therein. The elongated container comprises a circular shaft extending axially therein adapted for receiving paper rolls stacked one on another such that the paper rolls can rotate thereabout. An abutment plate is disposed in the elongated container on a biasing spring and is free to translate longitudinally on the circular shaft in the elongated container. The abutment plate is adapted for receiving a bottommost paper roll of the stacked paper rolls thereon. The biasing spring is calibrated to support the stack of paper rolls through the abutment plate such as to align an uppermost paper roll opposite the aperture in the peripheral wall, wherein the uppermost paper roll is in a dispensing position. The biasing spring gradually moves the abutment plate upward as paper is dispensed from the uppermost paper roll and weight of the stacked paper rolls diminishes such that a subsequent paper roll gradually reaches the dispensing position.

Abstract: An immunoassay for selectively measuring human C-peptide as well as a kit therefor is disclosed. In the method, human C-peptide contained in a sample, a first anti-human C-peptide antibody, and a second anti-human C-peptide antibody which is immobilized on a solid support are reacted to form an immune complex among these three components. The formed immune complex is separated from the non-reacted antibodies and sample; and then the separated immune complex is quantified. The first antibody recognizes an epitope existing in the region from 1st to 10th amino acid residue from the N-terminal of the human C-peptide, and the second antibody recognizes an epitope existing in the region from 1st to 16th amino acid residue from the N-terminal of human C-peptide; with the proviso that the first and second antibodies do not recognize the same epitope so that they can simultaneously bind to said human C-peptide.

IPC: G02B1/10
Filed: 1999-11-19
Abstract: A coated optical lens includes a lens element and a coating on the surface of the lens element. The coating exhibits a substantially balanced reflectance from the centre to a radius proximate the edge of the lens element. The term "substantially balanced reflectance" means that where the thickness of the coating varies across the surface of the lens, the lightness, hue and chroma of the reflectance vary in a balanced manner such that variations in visual appearance are either imperceptible or generally acceptable to an observer.  For example, variations in chromatic attributes, such as hue, from the centre to the edge of the lens may be balanced by a reduction in lightness from the centre to the edge. Preferably, the lens element includes a surface of high curvature upon which the balanced reflectance coating is deposited.

Title: M x n optical matrix switch
Inventor: AO ERIC RONG
IPC: G02B6/35
Filed: 2001-08-23
Abstract: An M x N optical switch in which the focal lengths of the collimating lenses are adjusted so that the waists of the Gaussian beams exiting the collimating lenses are focused on reflecting elements, which are positioned along a diagonal of the array of reflecting elements. This arrangement increases the number of beams that are symmetrical about the waist position, which increases the coupling efficiency. The best possible arrangement occurs when all of the waists are equal in diameter, thereby ensuring that for every output port the distances from the waists to the focusing lens are identical.

Abstract: The invention is directed to a method for cell selection in a cellular telecommunication system. According to the invention, cell identification information is attached as a parameter to an RRC message initiating the state change of the mobile station to the cell-connected state. Advantageously, the network selects a cell to be suggested as the cell for use by the mobile station in the cell-connected state, and the network indicates said cell by attaching cell identification information as a parameter to said RRC message. Consequently, the mobile station may make the final selection of the cell, and indicate the selected cell to the network by attaching cell identification information as a parameter to a second RRC message, such as the response message to the RRC  message initiating the state change.

Title: Recombinant eggs and gene cloning and expression vectors based on avian adenoviruses
Inventor: BLYDEN ELUEMUNO R
IPC: A61P31/20
Filed: 2000-09-15
Abstract: We describe a new technology for producing eggs containing recombinant proteins based on the novel use of avian adenoviruses (AAV). Adenovirus infected embryonated eggs are used as the host organism. The proteins synthesized are isolated in high amounts per egg and purified excluding time - consuming steps of purification. As far as is known, the mechanisms of translation and post-translational modification of proteins in avian species  fully resembles those of other higher eukaryotes such as humans, veterinary animals, and plants. In contrast with bacterial, yeast and plant host system s for producing recombinant proteins, avian embryos allow isolation of protein s in biologically active form free of endotoxins. The combination of high productivity and possibility of obtaining proteins in native form makes the system a unique choice for biotechnology, much more favorable than other hos ts currently being used for this purpose.

Title: Method and system for frame and protocol classification
Inventor: HEDDES MARCO
IPC: H04L12/56
Filed: 2000-12-21
Abstract: A system and method of frame protocol classification and processing in a system for data processing (e.g., switching or routing data packets or frames). The present invention includes analyzing a portion of the frame according to predetermined tests, then storing key characteristics of the packet for use in subsequent processing of the frame. The key characteristics for the frame (or input information unit) include the type of layer 3 protocol used in the frame, the layer 2 encapsulation technique, the starting instruction address, flags indicating whether the frame uses a virtual local area network, and the identity of the data flow to which the frame belongs. Much of the analysis is preferably done using hardware so that it can be completed quickly and in a uniform time period. The stored characteristics of the frame are then used by the network processing complex in its processing of the frame. The processor is preconditioned with a starting instruction address and the location of the beginning of the layer 3 header as well as flags for the type of frame. That is, the instruction address or code entry point is used by the processor to start processing for a frame at the right place, based on the type of frame. Additional instruction addresses can be stacked and used sequentially at branches to avoid additional tests and branching instructions. Additionally, frames comprising a data flow can be processed and forwarded in the same order in which they are received.

Abstract: Method and systems for assessing wide area performance of a crop variety usi ng a linear mixed model that incorporates geologic statistical components and includes parameters for fixed effects, random effects and covariance (J20). A wide area database is constructed that includes covariate data, spatial coordinates of testing locations of one or more crop varieties, geographic areas in which the testing location reside, and performance trait values of one or more crop varieties (H25, H30). The parameters for the fixed effects,  random effects and covariances are estimated by fitting the linear mixed mod el with data in the wide area database. Long term expected performance of the crop variety may be estimated using the parameter estimates. Average performance of the crop variety for a given time period may be predicted usi ng the parameter estimates.
