    Abstract: Planar hergestellte Struktur (201, 401, 501, 601) zur Verwendung in einem zugehörigen Markierungsgerät, das aus mehreren Markierungsgerätearten zur Erzeugung von Markierungen auf einem zugehörigen Substrat ausgewählt ist, wobei die hergestellte Struktur umfasst:ein Substrat (206),einen selbsthebenden Federfinger (200) mit einem nicht angehobenen Ankerbereich (208), der an dem Substrat angebracht ist, und einem Auslösebereich (202), der sich über dem Substrat (206) erstreckt, wobei der Auslösebereich (202) ein zum Rand des nicht angehobenen Ankerbereichs (208) zugewandtes Ende (212) und ein abgewandtes Ende aufweist, wobei das abgewandte Ende eine Spitze (202T) umfasst, die ausgebildet ist, als ein elektrostatischer Feldkonzentrator zu dienen, um die elektrostatische Extraktion von Markierungsfluiden aus einem Reservoir mit Markierungsfluiden des zugehörigen Markierungsgeräts in Richtung einer zu markierenden Oberfläche zu ermöglichen.

    Abstract: A level control mechanism is provided for a biofluid drop ejection device which ejects biofluid drops in small volumes. The biofluid drop device includes a drop ejection mechanism having a transducer (16) which generates energy used to emit the biofluid drops. A reagent cartridge (12) or biofluid holding area holds a biofluid, isolated from the drop ejection mechanism to avoid contamination between the biofluid drop ejection mechanism and the reagent cartridge. The reagent cartridge is connected to the drop ejection mechanism such that upon operation of the mechanism, the biofluid is emitted in controlled biofluid drops. A level sensor is positioned to sense a height of the biofluid within the cartridge. Upon sensing the height of the biofluid below a certain level, an adjustment is made to the height by providing at least one of additional biofluid to the cartridge, and raising the level of the entire reagent cartridge.

    Abstract: A multiple-ejector system for printing arrays of biofluids include a tooling plate having a plurality of sets of tooling pins extending outward from the surface of the tooling plate. A printed circuit board is provided having pairs of power connection pins and ground return pins extending from a surface of the circuit board. A plurality of biofluid drop ejection units are provided and include alignment grooves and at least a transducer. Each of the plurality of biofluid drop ejection units are connected to a corresponding one of a set of tooling pins by connection of the tooling pins and alignment grooves. The power connection pins of the pairs are in operational connection with respective transducers and the ground return connection pins of the pairs are in operational connection with a body portion of the drop ejection units. The different drop ejection units will contain different biofluids which are to be emitted onto a substrate. Verification of drop ejection units containing biofluids, may be obtained in one embodiment through the use of an optical scanner. Detection of drops at defined locations provides a verification that validates a properly formed spot is present on a substrate, and is in the correct position.

    Abstract: In a large area display system, multiple persons may work together with multiple input devices for supplying and receiving information in an interactive system with a single large area display. The large area display system comprises a screen (20) wherein computer generated information is projected upon one side of the screen, and users interact with the computer (29) from the opposite side of the the screen (20). Data coordinates for an input device corresponding to a pseudo image sensed by the receiving subsystem electronics are provided to the controlling computer (29). The input data coordinates from the pseudo image are normalized for variations due to frequency dependence and electronic drift. The normalized data coordinates are looked up in a calibration table to account for distortion in the pseudo image detection electronics. Screen coordinates corresponding to pixel locations on the large area screen (20) are found by interpolation from the data from the calibration table. The calibration table is prepared off-line, based on a bicubic spline interpolating function which is then compressed using a delta compression scheme. During on-line operation of the system, screen coordinates are looked-up directly from the compressed table. The screen coordinates are then jitter smoothed to provide a smooth path of response closely conforming to original input locations. The jitter smoothing method uses an exponential function based on the magnitude of the change in the position of the input.

    Abstract: An input device for simultaneously entering position and function information into an electronic system having a viewing surface upon which is displayed information generated by the electronic system. A light pen is provided for projecting a light spot onto the viewing surface for indicating the position of a location marker thereon and for indicating a function to be performed. The optical output of the light pen is modified to represent the selected function. A sensor receives the light spot and, in conjunction with discrimination electronics, determines the location of the centroid of the light spot relative to the viewing surface, and determines the function to be performed.
