摘要:
The invention provides conductivity control agent comprised of a polymeric material containing hydroxyalkylphosphonium (2-hydoxyethoxycarbonyl)arylsulfonate salts. The conductivity control agents can be used with semi-conductive rolls, belts and other biasable members. The inclusion of the conductivity control agent in the polymeric or polyurethane elastomers extends the electrical life of the polyurethane biasable member in low humidity environments. Additionally, the resistivity of the elastomeric polyurethane or polymer on the biasable member is controlled to a desirable value by adjusting the conductivity control agent level in the polymeric or polyurethane elastomers.

A roller bag having integral thereto a battery and a small alternator geared to recharge the battery when the wheels of the roller bag are rotated. During times of commuting, such as within an airport terminal, between a terminal and a rental car facility, or in route to a hotel, the battery will remained charged and available to the mobile user to provide a reliable source of power. A power terminal is further integrated into the bag providing external access to the battery, which power terminals permit connection to portable electronic devices, and may include retractable cords and programming tips.

In a method of making a gypsum slurry, a polycarboxylate dispersant, a modifier and a hydraulic material comprising stucco are selected for use in the slurry. These components are then combined with water to form a slurry, where the modifier is added to the slurry prior to formation of a slurry phase by the water, the stucco and the dispersant. The modifier has been shown to be less effective when added after the dispersant and stucco have been contacted in an aqueous slurry. In a preferred embodiment, an amount of stucco is obtained and the modifier and dispersant are selected. A predissolved solution of a dispersant and modifier is prepared in water to form a solution prior to the addition of the stucco. After mixing the solution, the stucco is added to form the slurry. Optionally, the slurry is then shaped into a product and allowed to set.

A system and method is provided for an on-demand advertising information vault so that advertisers may establish accounts for distributing advertisements on-line to potential subscribers. The on-demand information vault also provides for consumers to subscribe to advertisements from advertisers based on the consumer's preferences of categories of products or services. An advertiser may also establish rewards for viewing their advertisements for inducing consumers to subscribe to their advertising service. In this way, a consumer may agree to receive only certain types of advertisements and receive remuneration for viewing the advertisements. The vault mechanisms may also provide for protecting the identities of the consumer and advertiser and avoids misusing personal data by others by employing security measures.
摘要:
A method for making an image of an object including depth information comprising the steps of: illuminating the object with a periodic pattern of light from an illuminating arrangement; the illuminating arrangement being such that the pattern is in focus in a focal plane and defocuses progressively away from said focal plane; the object being placed such that different parts of it are at different distances from the focal plane; capturing image data from the thus-illuminated object; analyzing the captured image data to extract depth information based on the extent of defocusing of the pattern; and displaying an image of the object without the pattern and with depth information. Apparatus or carrying out the method, comprising an illuminating arrangement adapted to illuminate the object with a periodic pattern of light; the illuminating arrangement being such that the pattern is in focus in a focal plane and defocuses progressively away from said focal plane; the object being locatable with respect to the illuminating arrangement such that different parts of it are at different distances from the focal plane; image data capturing means adapted to capture image data from the thus illuminated object; data analysis means adapted to analyze captured image data to extract depth information based on the extent of defocusing of the pattern; and image display means for displaying an image of the object without the pattern and with depth information.
摘要:
A sender-specified courtesy notification scheme to delay notification by a receiving device of the receipt of a data message is disclosed. A sender may specify a notification parameter defining a delay and send the parameter in association with the data message to a recipient. The recipient's receiving device evaluates the parameter and notifies in response. Local notification data defined by the recipient may also be evaluated. Received data messages subject to delayed notification may be hidden by the receiving device or quietly displayed (e.g. as per other received messages) until the expiry of the delay. Notification parameters and data can be formulated as one or more rules which may take into account the current location of the receiving device. A notification delay may be ignored in certain situations depending on recent use of the receiving device.

Provided are methods for synthesizing radiotracers, including no carrier added (n.c.a.) tracers suitable as PET scan tracers that contain a 18F—P bond. The radiolabeled products may be synthesized from precursors including phosphorus(V) and/or phosphorus (III) atoms bound to a suitable leaving group or group(s). For example, precursors incorporating a nitrophenoxy leaving group bound to a phosphorus(V) atom tend to exhibit an acceptable combination of stability and reactivity and also tend to allow the precursor compound(s) to be separated more easily from the 18F-labeled products. The methods disclosed herein for producing radiolabeled compounds incorporating a P—18F chemistry may particularly useful radiolabeling oligonucleotides, phospholipids, phosphorilated proteins, sugars and steroids for use as PET radiotracer compounds for medical imaging applications.

A security system in a vehicle extends its protection to installed equipment of the vehicle, such as audio components, navigation systems, and entertainment systems. The installed equipment is armed and disarmed by the security system, preventing the equipment from normal functioning after unauthorized removal. The security system further enables programming, monitoring, and diagnosing of the installed equipment through the security system's remote control, through a configuration and maintenance tool that connects to the security system, or through other items of installed equipment within the vehicle, such as a rear-seat entertainment system.
