Abstract: Monoclonal antibody reagents that recognize the SARS-coronavirus (SARS-HCoV) are needed urgently. In this report we describe the development and immunochemical characterisation of mAbs against the SARS-HCoV based upon their specificity, binding requirements, and biological activity. Initial screening by ELISA, using highly purified virus as the coating antigen, resulted in the selection of seventeen mAbs. Five mAbs exhibited Western immunoblot reactivity with the denatured spike protein, of which two demonstrated the ability to neutralize SARS-HCoV in vitro. Another four Western immunoblot-negative mAbs also neutralize the virus. These antibodies will be useful for the development of diagnostic tests, pathogenicity and vaccine studies.

Abstract: A system of supplying power between portable devices includes a power providing portable device and a power receiving portable device. The power providing portable device includes a rechargeable battery, a voltage regulator, a voltage selector, and an output port. The voltage regulator is used for regulating output voltage from the rechargeable battery according to the voltage selector and transmitting the power via the output port to the power receiving portable device. The power receiving portable device includes an input port for receiving power from the providing device and transmitting power to a rechargeable battery of the receiving device. A portable device used in the system for either receiving or supplying power is also disclosed in the invention.

Abstract: A mouse includes a left button, a right button, a touch sensing unit and a processing unit. The left button and the right button generate click signals in response to click operations. The touch sensing device generates touch positional signals when the left or right button is touched. The processing unit is used to receive the touch positional signals, calculate y-coordinate values of all points in the touched areas; select two significant points respectively from the left touched area and the right touched area; compare the y-coordinate values of the two significant points to generate a comparison result; confirm a current operated mode; if the confirmed operated mode is a left handed operation, send a control signal with a left-button identifier to a computer configured therewith; if the confirmed operated mode is a right handed operation, send a control signal with a right-button identifier to the computer configured therewith.

Abstract: An LED light source model has a substrate, at least one bare LED chip, a preformed phosphor lamina with at least one inner opening, and an optical light collecting element. The substrate has a top face, a bottom face and at least one chip mounting area defined on the top face. The frame is mounted on the top face and the inner opening corresponds to the chip mounting area. The bare LED chip is mounted in the chip mounting area. The preformed phosphor lamina is mounted over the bare LED chip and mounted in the corresponding inner opening. The optical light collecting element is mounted on the top face to collect the light from each preformed phosphor lamina to increase the light intensity. Each preformed phosphor lamina is preformed to ensure that two opposite faces are flat, so the light intensity from all of the bare LED chips is even.

Abstract: An LED light source model has a substrate, at least one bare LED chip, a transparent layer and an optical light collecting element. The substrate has a top face, a bottom face and at least one chip cup defined on the top face. The at least one LED chip is mounted in the at least one chip cup. The transparent layer is formed on the top face to seal the at least one chip cup. The optical light collecting element is mounted on the top face to collect the light from each chip cup to increase the light intensity. A plurality of fins or recesses are formed or defined on the bottom face to increase a heat dissipation area. When each bare LED chip is in operation mode, heat from the bare LED chip will be conducted to the bottom face and then dissipate to the ambient air quickly.

Abstract: A technique for managing a web page having at least one URL supporting search engine preferred Universal Resource Locator (URL) links through URL mapping and shadow page support is provided. Because a search engine crawler typically does not want to crawl through dynamic URLs, a search engine friendly page would typically contain static URLs. Support is provided for obtaining the web page containing the at least one URL link and determining the at least one URL link to be of a dynamic format then converting the dynamic format of the at least one URL link into a static format. Next, a shadow page of the web page is created, containing the static format link, and placed in the shadow page repository. A web application server may then enabled to provide a URL mapping function to convert such a static URL to a desired dynamic format, based on a provided mapping file. Web administrators or developers may then define an entry in such a mapping file for each URL key that needs to be mapped.

Abstract: The present invention provides an intelligent and efficient system (600) and/or method (600) for automatic notification and/or enforcement of legal traffic speed limits and stops, comprising roads, streets, highways, construction zones, accident sites, and anywhere needed (400) installed at appropriate advanced locations with information tags (101) written with information including the according speed limit and/or stop information and vehicles (500) installed or built-in with information readers (201) capable of wirelessly and automatically reading information from the information tags (101) while the vehicles (500) travel. The read and other on-the-road information is displayed on visual displays (302) inside vehicles (500) and/or is voiced via audio devices (303) inside vehicles (500) for automatically notifying the vehicle drivers.

Abstract: This invention relates to a process for preparing a patterned layer of aligned carbon nanotubes on a substrate including: applying a photoresist layer to at least a portion of a surface of a substrate capable of supporting nanotube growth, masking a region of said photoresist layer to provide a masked portion and an unmasked portion, subjecting said unmasked portion to electromagnetic radiation of a wavelength and intensity sufficient to transform the unmasked portion while leaving the masked portion substantially untransformed, said transformed portion exhibiting solubility characteristics different to said untransformed portion, developing said photoresist layer by contacting with a solvent for a time and under conditions sufficient to dissolve one of said transformed and untransformed portions of the photoresist, leaving the other portion attached to said substrate, synthesising a layer of aligned carbon nanotubes on regions of said substrate to which said remaining photoresist portion is not attached to p

Abstract: An adjustable jet flame utility lighter includes a hand operative adjustable button rotatably mounted on a casing of the lighter for controlling the flow of gas through a gas emitting nozzle and a holding means mounted on the casing for holding a depressed pusher button in such a manner the lighter is kept in an ignition position. The holding means includes a guiding through channel provided at a bottom of the casing aligning with the pusher button and a holding element movably held with the guiding through channel in such a manner the holding element is arranged to mount on a ceiling of the pusher button so as to retain the lighter in the ignition position. At the same time when the lighter is in use, a user is able to adjust the size of the torching flame by rotating the hand operative adjustable button.

Abstract: A piezoelectric lighter incorporates with a safety device which includes a pusher cap slidably mounted on a pusher cavity of a casing in a vertically movable manner and attached to a top end of a piezoelectric unit; a locking member fitting on an upper portion of the casing, wherein the locking member having a stopper latch locking up the pusher cap for blocking the pusher cap in a vertical manner. The safety device further includes a resilient unit, which is articulated on an axle mounted on the upper portion of the casing, normally urging and retaining the locking member locking up the pusher cap so as to block any downwardly movement of the pusher cap and thus prevent the ignition operation of the piezoelectric unit. Thereby, in order to ignite the piezoelectric lighter, the locking member must be pressed transversely inward to move the latch of the locking member out of the edge of the cap body of the pusher cap.
