Abstract: A system and method for embedding data transmission in a web page, enabling communication between a user and a representative includes requesting a web page which includes at least one nondisplay space object and at least one display space object which is configured to transmit data to and from a backend server without the necessity of refreshing the current page, redirection to another web page, or posting to another web page. The web page is rendered and includes at least one display space and at least one nondisplay space according to the display space object and the at least one nondisplay space object. The display space object may connect with the backend server to form a persistent communication channel to enable real-time communication, and/or it may transmit data through invisible HTTP/HTTPS requests, or both. A persistent communication channel may be initiated by the display space object, triggered by the end user, or initiated by the backend representative.

Abstract: A technique for assessing the progression of multilateral dysfunction, e.g. bilateral diseases is described. The process consists of two stages: firstly, a ‘health measure’ is computed for each of the features of the multi-lateral dysfunction. One example is in terms of the progression of Parkinson's disease by applying it to the uptake of imaging agent in the two striata of the brain, which can be viewed using SPECT imaging. In this example, a characteristic graph for each striatum is matched to a family of such graphs in order to quantify the state of each striatum as a health measure. Then the lower health measure is plotted against the higher health measure. This point is then projected onto a previously computed disease progression trajectory which is used to assign a percentage to the progression of the disease, from 0% normal to 100% extreme progression of the disease. In addition to the disease progression percentage, the technique also provides a confidence measure of the accuracy of this estimation.

Abstract: A method for producing a device for piercing a body surface is disclosed. A sheet (200) is provided having opposite first and second faces. A plurality of microprojections (304) and openings (302) are formed through the first and second faces of the sheet (200). The first face of the sheet (200) is positioned adjacent a die (402) having a plurality of cavities (404) corresponding to the plurality of microprojections (304) of the sheet (200) in such a way that each of the microprojections (304) of the sheet (200) is positioned adjacent a corresponding cavity (404) of the die (402). An elastomeric material (410) is then forced against a second face of the sheet (200) and into the cavities (404) of the die (402) to deflect the microprojections (304) of the sheet (200) into the cavities (404) of the die (402).

Abstract: A fuel tank comprising two or more sections bonded together with an adhesive which bonds to low energy surface materials and has fuel barrier properties.

Abstract: The disclosed invention is a means of transporting personal items such as those commonly taken to do shopping, and storing them in an easily accessible manner to a shopping cart or stroller handle. The device can also include a second side for children riding in the child's seat of a shopping cart, thereby allowing storage for items of entertainment to the child or even a pillow for their comfort during the shopping excursion. The device is comprised of one or more flaps, at least some of the flaps including pockets that are capable of distinctively storing items that would be necessary to a shopper or child, whichever the case may be. The invention includes a pliable portion that is capable of flexing around and fastening to the handle of a shopping cart or stroller and in doing so creating accessible pockets that are exclusive to each the child and the shopper.

Abstract: A receiver for orthogonal frequency division multiplexed signals includes means (14) for calculating the (discrete) Fourier Transform of the received signal, and means (20) for calculating the phase error due to local oscillator errors.

Abstract: A tooling assembly for a continuous extrusion apparatus includes a die top positioned in a shoe arranged to be urged into contact with a rotating wheel having a circumferential groove. An abutment body is positioned as a sliding fit in a recess provided in the die top and is formed with a spine arranged to project into the circumferential groove and with shoulders flanking the spine arranged to co-act with the cylindrical surface of the wheel adjacent an abutment face. The abutment face lies in a plane inclined slightly to an axial plane through the wheel and the faces on the abutment body seating on faces of the recess are aligned such that forces arising during extrusion act to urge the abutment body into the recess.

Abstract: An operator assembly for a casement window that includes a frame and a pane carrying sash. The operator assembly is mounted to the frame and an elongated arm connects the operator assembly and the sash. Movement of the arm moves the sash relative to the frame for opening and closing the window. The operator arm includes a pivotally mounted and linerally moveable handle which is moveable between a first and second position. A ratchet-type gearing system is provided to connect the handle and operator arm and to effect movement of the operator arm in response to movement of the handle. A selector associated with the handle and gearing system is provided to effect and control the direction of sash movement in response to the movements by the handle. A locking system is provided to engage the gearing system to prevent movement of the gearing system due to loads on the sash that are transmitted to the gearing system through the sash and operator arm.

The valve spool slides in the bore under the influence of gravity between a first position in non-inverted flight wherein one land seats on one of the valve seats to seal the top drain and a second position in inverted flight wherein the other land seats on the other valve seat to seal the bottom drain.

Abstract: A method and apparatus for measuring the viscoelastic characteristics of a sample of a viscous liquid or gel contained within a closed can or other cylindrical vessel. The can and sample are subjected to torsional oscillation about a vertical axis by an oscillation source through an elastic coupling member, the oscillation source operating either (i) at a fixed, predetermined frequency or (ii) at the resonant frequency of the can and sample. Measurements are made of the amplitude of oscillation of the can and sample and of either (i) the angular phase difference between the oscillation of the can and sample and those of the source or (ii) the resonant frequency of the can and sample. The measured data may be used either to compare the sample with a standard material or to calculate viscoelastic moduli of the sample.

Abstract: Sequential/interlace scan conversion of NTSC or PAL color television signals is effected by an encoder the output of which is connected to the input of scan conversion apparatus. Controllable phase shift means is included in either the color signal input or the subcarrier input of the encoder and is adapted to vary the phase of the modulated subcarrier for each line of the received color signal by an essentially integral number of quarter cycles in dependence upon the line number. The control is such that the conversion apparatus provides an encoded output signal with the color subcarrier in PAL or NTSC format. The invention can also be used in converting between different types of interlace systems.
