摘要:
A paperboard product having at least one layer of bleached or semi-bleached pulp and having improved smoothness and reduced bulk loss. For paperboard having sizing without pigment, the smoothness on the printed side, measured by the Parker test is better (lower) than 6.5 when measured using a pressure of 10 kgf/cm2 while the smoothness measured by the Hagerty/Sheffield test is not below 280 Sheffield units. For paperboard having sizing with pigment, the Parker smoothness is less than 5.0 and the Hagerty/Sheffield smoothness is not less than 180 Sheffield units. The web is finished by applying temperature and moisture gradients, then smoothing the web surface using extended nip calendering. The surface temperature of the calendering roll is maintained at 250-400° F. Prior to entering the extended nip, the web surface is moisturized using steam showers. The nipload applied in the heated extended nip is preferably between 300 to 2,500 pli.
摘要:
A multilayer linerboard product having a top layer made up of bleached/unbleached virgin or recycled pulp and at least one bottom layer made up of unbleached pulp. The external surface of the top layer has reduced gloss mottle and improved printing properties. In particular, the top surface of the multilayer linerboard has a Parker smoothness less than 6.5 and a Hagerty/Sheffield smoothness in the range of 240 to 280. Print voids on a flexo printed product are less than 0.20% (by area) as measured by image analysis. These improvements are achieved in an extended nip calender section having a heated calender roll, a backing roll or shoe and a conformable belt. Preferably, the nip width is 1 to 25 cm. The temperature of the surface of the heated calender roll is preferably maintained in the range of 300 to 500° F. The nipload between the heated calender roll and the conformable belt is preferably maintained in the range of 500 to 2,500 pli.

摘要:
Methods and systems for coauthoring in a drawing tool are described. One computer-implemented method includes displaying a first user name of a first user in association with a first shape on a drawing, and receiving an indication that a second user is collaborating on the drawing. The method includes receiving an indication that the second user has modified a second shape on the drawing. The method also includes, in response to the indication that the second user has modified the second shape, displaying a second user name of the second user in association with the second shape on the drawing. The methods and systems can also include, in some cases, periodic sharing of metadata among coauthors, to indicate edits made by other coauthors.
摘要:
A system and method for automatically changing the operation of a mobile device in response to a presence of information is described. In some examples, the system determines an information capture device is proximate to text, automatically changes operation of the capture device to a certain mode, captures the text, and performs an action associated with the captured text.
摘要:
A method is provided for determining optimum positions in a region for a plurality of sensors that are capable of detecting occurrence of a hazard in the region. The hazard may be a chemical, biological, and/or radiological hazard in solid, liquid or gas form. A “simulation cache” is provided that stores data representing interaction of the hazard with sensors at each of the plurality of candidate locations in the region for each of the plurality of sensor types. Data is then retrieved from the simulation cache as needed for evaluation a particular candidate sensor solution comprising one or more sensors of one or more sensor types at corresponding ones of the candidate locations. An optimization algorithm may be used to select a candidate sensor solution. The data that is retrieved from the simulation cache for a selected candidate sensor solution is evaluated with respect to certain performance criteria. The simulation cache greatly reduces the time required to generate an optimum sensor layout because it separates the hazard modeling and sensor performance modeling from the optimization algorithm. By capturing this data at one time for storage in the simulation cache, it is not necessary to re-run the hazard simulations for each candidate sensor location generated by the optimization algorithm.
摘要:
A Non-Dispersive InfraRed gas sensor has the LED radiation source and photodiode detector side by side in a dome shaped gas chamber. The mirror coated inner surface of the dome reflects light from the LED to the photodiode. The reflecting surface in one embodiment has a plurality of semi-toroidal sub surfaces, such that radiation originating from a point on the LED is unfocussed as it converges on the photodiode. The LED and photodiode may be mounted on a bridge printed circuit board extending along the diameter of the dome housing. The bridge height is adjustable during assembly to optimise the radiation's incidence onto the photodiode.

A chimeric Shiga toxoid according to the invention contains an enzymatically-inactivated StxA subunit and a native StxB subunit. This hybrid Shiga toxoid induces the production of broadly cross-reactive species of antibodies against Shiga toxin following immunization. The StxA subunit is modified so that it is enzymatically inactive. The invention thus encompasses the Shiga toxoid or fragments thereof and the nucleic acid sequence of the Shiga toxoid or fragments thereof. The invention further encompasses the production of a Shiga toxoid, the production of antibodies using the Shiga toxoid and methods of productions, and an immunogenic composition containing the Shiga toxoid.

The present invention is directed to a mixture of at least two different alkylated phenolphthalein ester compounds. Specifically, the present invention is directed to a mixture of at least two different compounds of formula I: wherein R1 represents a straight chain alkyl group having 1 to 11 carbon atoms; R2 represents a hydrogen atom or a group of the formula C(O)R4 where R4 is a hydrogen atom or a straight chain alkyl group having 1 to 11 carbon atoms; X2-X5 independently represent hydrogen; X6-X13 is same or different, and represents hydrogen or a straight or branched chain alkyl group having 1 to 12 carbon atoms. It further relates to a marker composition containing said mixtures dissolved in a solvent.
摘要:
A circuit testing and control approach involves configurable switch control for automatically detecting and routing test signals along a plurality of test circuit paths. According to an example embodiment of the present invention, graphical user interface (GUI) (240) includes stored computer-executable code that, when executed, causes a micro-computer circuit to send configuration signals to a microcontroller (220). A configurable circuit (215) coupled to the microcontroller is then configured by the microcontroller, in response to the configuration signals, for routing test signals using controllable switches. In one implementation, the configurable circuit includes circuits on inter-connectable circuit boards (210, 250, 260), with sense nodes for detecting the presence of an inter-connectable circuit board coupled to another. In response to the detected presence (or lack thereof), the controllable switches control the routing of the test signals between the inter-connectable circuit boards. The configuration signals are used for one or more of actively controlling the microcontroller, programming the microcontroller (e.g., storing program code therein) or requesting data from the microcontroller. With these approaches, automatic switching of test signal paths, on an individual circuit and in connection with other circuits, is achieved without necessarily physically accessing the configurable circuit.
