Abstract: Methods and apparatuses for controlling gain of a single stage cascode FET amplifier are presented. According to one aspect, a series-connected resistor and capacitor is coupled to a gate of a cascode FET transistor of the amplifier, the capacitor providing a short at frequencies of operation of the amplifier. According to another aspect, values of the resistor can be used to control gain of the amplifier. According to yet another aspect, the resistor is a variable resistor whose value can be controlled/adjusted to provide different gains of the amplifier according to a linear function of the resistor value. An input matching network coupled to an input of the amplifier can be used to compensate for different noise figure degradations from different values of the resistor.

Abstract: The invention provides compositions, methods, and kits for the diagnosis or detection of active, latent, or prior infection with human herpesvirus 8 in a subject sample.

Abstract: This invention provides an apparatus for particle sorting, particle patterning, and methods of using the same. The sorting or patterning is opto-fluidics based, in that particles are applied to individual chambers in the device, detection and/or analysis of the particles is carried out, such that a cell or population whose removal or conveyance is desired is defined, and the cell or population is removed or conveyed via application of an optical force and flow-mediated conveyance or removal of the part.

Abstract: A printing apparatus has been developed that prints inkjet images on a continuous web with a configurable number of distinct ink colors.

Abstract: A zero-latency risk-management system and method useful in, for example, sponsored market access or in-house trades. The zero-latency risk-management system comprises an out-of-band risk monitor computer and a kill-switch. The kill-switch is in-line between order receipt and trade placement, but the out-of-band risk monitor computer operates in parallel with the order processing, thus eliminating latency in the trade. The out-of-band risk computer monitors orders as they flow through the system and updates any risk metrics based on those orders. Kill-switch threshold levels may be set in the risk computer to be, for example, the desired level of risk, minus the maximum amount of risk that a subsequent new order could incur. If the risk computer determines that an order has breached this kill-switch threshold, it activates the kill-switch to prevent additional order entry that could breach the actual threshold.

Abstract: A method of applying a protective coating over ink printed media in a digital printing engine whereby horizontally discharging ink jet nozzles arranged in a vertical array, discharging a protective coating onto the marked surface of media disposed on a belt in vertical disposition. The coated media is then transported vertically to an adjacent source of ultraviolet radiation for curing the protective coating.

Abstract: A method of printing an image on a substrate comprises determining a pile height differential for the image. A clear marking material is added to the image printed on the substrate in response to the determined pile height differential. Adding the clear marking material substantially reduces the pile height differential between two areas of the printed image. The clear marking material may be a clear ink or a clear toner material. The substrate on which the image is printed may comprise a plurality of sheets, a roll or other length of print media. The step of adding clear marking material to the image may include substantially leveling the printed image using the clear marking material. In at least one alternative embodiment, the step of adding clear marking material to the image includes adding at least one patch of clear marking material to the printed image.

Abstract: An inkjet printer has been developed that reduces the effects of show-through by depositing ink onto a cooled print medium. The inkjet printer includes a printhead and a cooler. The printhead is configured to eject ink onto an ink receiving member as the ink receiving member is transported along a portion of a media path through the inkjet printer. The cooler is positioned proximate the media path to cool the ink receiving member prior to the printhead ejecting ink onto the ink receiving member.

Abstract: A system enables ink on an image receiving member to be re-distributed to reduce banding effects in the image. The system includes an ink applicator for applying ink to form an ink image on an image receiving member as it passes by the ink applicator; a plenum chamber for receiving a flow of pressurized fluid from a fluid source, and at least one opening in the plenum chamber to direct the flow of pressurized fluid from the plenum towards the ink image on the image receiving member to re-distribute the ink on the image receiving member.

Abstract: Methods and devices for forming, such as by printing, high quality, high throughput, ultraviolet curable gel ink images on flexible substrates for packaging applications are disclosed. The methods and devices have excellent image quality and do not require pinning of the ink during color printing or nitrogen inerting during curing.

Abstract: A method and system are provided for executing a transaction relating to a first futures contract. The first futures contract involves a tradable asset, such as crude oil or another commodity, and a first contract price and a first settlement price expressed in a first currency, such as U.S. dollars. The first settlement price is updated on a periodic basis, typically daily. The method involves providing a second futures contract having an underlying instrument that includes the first futures contract. The second futures contract includes a second latest possible delivery date and a second contract price and a second settlement price that are denominated in a second currency. The second settlement price is updated periodically. A periodic mark-to-market operation credits or debits a buyer of the second futures contract based on the periodic update to the second settlement price.
