Abstract: An optical interrogation system is described herein that can interrogate a label-independent-detection (LID) biosensor and monitor a biological event on top of the biosensor without suffering from problematical parasitic reflections and/or problematical pixelation effects. In one embodiment, the optical interrogation system is capable of interrogating a biosensor and using a low pass filter algorithm to digitally remove problematic parasitic reflections contained in the spectrum of an optical resonance which makes it easier to determine whether or not a biological event occurred on the biosensor. In another embodiment, the optical interrogation system is capable of interrogating a biosensor and using an oversampling/smoothing algorithm to reduce oscillations in the estimated location of an optical resonance caused by the problematical pixelation effect which makes it easier to determine whether or not a biological event occurred on the biosensor.

Abstract: A pagewidth inkjet printer is provided having a pagewidth printhead which has a plurality of printhead modules mounted end to end on a carrier to extend across a pagewidth with each printhead module incorporating a plurality of inkjet nozzles and the nozzles of at least one of the printhead modules being rotationally displaced relative to the carrier, and a printer controller for communicating ink dot data to the inkjet nozzles in accordance with a cumulative correction factor for each printhead module. The printer controller measures the amount of rotational displacement of the rotationally displaced printhead module to determine the cumulative correction factor to at least partially compensate for the rotational displacement.

Abstract: An aboveground fueling facility includes one or more vertical fuel supply tanks, each of which is positioned on a reinforced mounting pad on a fueling island that also includes one or more fuel dispensers.

Each of the vertical fuel supply tanks may have more than one compartment so as to permit different grades of fuel to be dispensed by the dispensers, including mixtures. Fueling lanes are defined between the vertical fuel supply tanks for permitting vehicular access to the fuel dispensers. A canopy for sheltering the fueling lanes is structurally supported by the vertical fuel supply tanks, and informational signage is provided on the canopy for providing information such as fuel pricing to the consumer.

Abstract: An optical reader system and method are described herein that can detect a lateral and/or angular misalignment of one or more biosensors so that the biosensors can be properly re-located after being removed from and then reinserted into the optical reader system. In one embodiment, the biosensors are incorporated within the wells of a microplate.

Abstract: In a virtual machine environment, a method and apparatus for the use of multiple heaps to retain persistent data and transient data wherein the multiple heaps enables a single virtual machine to be easily resettable, thus avoiding the need to terminate and start a new Virtual Machine as well as enabling a single virtual machine to retain data and objects across multiple applications, thus avoiding the computing resource overhead of relinking, reloading, reverifying, and recompiling classes. The memory hierarchy includes a System Heap, a Middleware Heap and a Transient Heap. The use of three heaps enables garbage collection to be selectively targeted to one heap at a time in between applications, thus avoiding this overhead during the life of an application.

Abstract: A printer architecture and memory card is described. The architecture can include an integrated circuit and a memory card. The memory card can include print swaths and bit-maps of thumbnail images associated with the print swaths. The thumbnail images can be displayed on the hand-held printer. A print swath associated with the selected thumbnail image can be printed.

Abstract: A printhead is provided having elongate printhead modules arranged to aggregately extend across a pagewidth and controllers for processing print data into dot data and for controlling the printhead modules in accordance with the dot data. Each printhead module has plural rows of ink ejection nozzles. The nozzle rows of at least one of the printhead modules are longer than the nozzle rows of the other printhead modules. The controllers control ink ejection of the nozzles of the printhead modules in accordance with the dot data. At least one of the controllers is arranged to control all of the printhead modules and at least one other of the controllers is arranged to control only one of the printhead modules.

Abstract: A printer is provided having a printhead of first and second elongate printhead modules and first and second printer controllers configured to receive print data and process the print data to output dot data to the printhead. The printhead modules are parallel to each other, are disposed end to end on either side of a join region, and are of different lengths. The first printer controller is arranged to output dot data to both the first and second printhead modules and the second printer controller is arranged to output dot data only to the second printhead module. One or more of the printhead modules has at least one row of print nozzles and at least two shift registers for shifting in the dot data to at least one row. Each print nozzle obtains the dot data from an element of one of the shift registers.

Abstract: A vent cannula includes a tubular base having a primary longitudinal passage therein with a primary distal tip for insertion into a body vessel. The base has a tubular junction interconnected and extending at an acute angle having a secondary passage therein communicating with the primary passage. A flexible tube is slidably retained within the secondary passage. The flexible tube has a flexible distal portion with a flexible distal tip thereon, a flexible proximal portion with a side port therein and with a proximal handle. The flexible tube is initially positioned at a “first position” wherein the flexible distal tip is within the secondary passage; and is slideable to a “second position” wherein the side port of the flexible proximal portion is at the junction of the primary and secondary passages, and the flexible distal tip is inserted into the primary passage and extended from the primary distal tip to thereby extend the functional tip of the cannula.
