Title: Standing stem log harvesting system
Inventor: JARMAN PHILIP S
IPC: A01G23/08
Filed: 1999-08-17
Granted: 2001-02-27
Abstract: A method of standing-stem log harvesting including the steps of preparing a tree for harvesting and then harvesting the same.      A tree is prepared for harvesting by topping the tree, cutting the tree part way through the trunk near ground level with two cuts lying in generally the same plane to leave holding wood between the resulting two generally parallel cut edges, and driving support wedges or the like into both said cuts to stabilize the tree trunk. The holding wood and the wedges maintain the trunk stable and upright until it is harvested, but the holding wood is readily frangible in response to a generally horizontal pivoting force applied to the trunk near the top thereof in a direction generally perpendicular to the cut edges.      For harvesting, the prepared tree is gripped near the top thereof, and a generally horizontal force is applied to the trunk at the point of gripping in a direction generally perpendicular to the cut edges, thereby breaking the holding wood. The severed log is then hoisted and removed to a selected drop site.      Apparatus for practising the standing-stem log harvesting method includes a helicopter and a grapple suspended generally under the center of gravity of the helicopter for gripping and hoisting the tree trunk.

Title: A method and system for environmental sensing and control within a computer system
Inventor: AHRENS GEORGE H
IPC: G06F11/30
Filed: 1999-09-23
Granted: 2005-04-12
Abstract: In accordance with the method and system of the present invention, a local processor utilizes registers arranged in a fault/mask/cache fashion for environmental control and sensing within a data processing system. The local processor continuously reads input data from a variety of environmental sensors in order to determine if a threshold level has been reached and a fault condition exists. Cache registers allow the local processor to store/pass detailed sensor information to system firmware within system processor(s). The local processor sets a fault bit within a fault register designed to cause an interrupt to the system level firmware if any of its bits are non-zero, indicating that a fault condition has occurred. A mask register is designed to allow the interaction of both the local processor and system processor(s) when an interrupt is being serviced and help keeps track of which interrupts are being serviced and which are yet to be serviced in the case of multiple interrupt sources. The system firmware will service the interrupt and set the mask bit. The action will signal the local processor that the system has acknowledged the interrupt and will take the appropriate action. The local processor may now post another fault, exactly like the first fault, by clearing the mask bit and causing a subsequent interrupt to the system. The fault, mask, cache, and both local and system processor(s) work together to provide a positive interlock for synchronizing their actions with each other.

Abstract: L'invention concerne une bobine mère à enroulement uniforme de tissu ouaté volumineux, dont l'uniformité de poids en feuilles, d'étirement dans le sens de production et de volume, est supérieure à l'uniformité correspondante de bobines mères enroulées selon les procédés de bobinage classiques. Le procédé consiste à acheminer la feuille de tissu sur une courroie de transfert (18) relativement imperméable à l'air qui traverse un intervalle sans portée entre deux rouleaux porteurs. La feuille (15) est ensuite transférée de cette courroie vers la bobine mère (25), au stade où ladite bobine est appuyée contre la courroie de transfert de feuille en un point de l'intervalle sans portée, moyennant quoi la déviation résultante est détectée. En réponse, il est possible de commander le changement de position du mandrin de la bobine mère, afin de maintenir la déviation susmentionnée dans des limites prédéterminées. On contrôle la tension de la feuille via la vitesse différentielle préétablie entre la surface située le plus à l'extérieur sur la bobine mère et la courroie de transfert.

Title: Force discrimination assay
Inventor: LEE GIL U
IPC: C12Q1/6816
Filed: 1999-01-20
Granted: 2010-05-18
Abstract: A sensor for a selected target species has (1) a substrate which has been chemically modified by attachment of substrate modifiers; (2) one or more magnetically active beads which have been chemically modified by attachment of bead modifiers, where these bead modifiers will have a binding affinity for the substrate modifiers in the presence of the target species, and a measurably different binding affinity for the substrate modifiers in the absence of the target species; (3) an adjustable source of a magnetic field for exerting a force on the beads; and (4) an imaging system, for observing and counting beads bound to said substrate. In a preferred embodiment, the invention further has a system for identifying clusters of beads, and for removing the effect of such clusters from measurements of the target analyte. As with other assays, the sensor relies on the ability of certain molecules to bind with specific target (analyte) molecules.  By coating the beads and the substrate with appropriate molecules, the beads will (or will not) bind specifically to the substrate in the presence (or absence) of the target molecule. When a magnetic field is applied to the substrate, the magnetic beads will be pulled away from the substrate. If the beads are specifically bound to the substrate, however, the beads will be retained on the substrate, indicating the presence (or absence) of the target species.

Abstract: An optical coherent processor or correlator for processing an input image produced by an imaging device illuminated by a coherent light source utilizes an optical key for preventing unauthorized use of the processor. The principle underlying processing apparatus and method according to the invention uses an optical lock in combination with an encoded software key superimposed on a filter image. The optical lock, which is preferably in hardware form, consists of a first optical mask implementing a locking mask function that is preferably complex (phase and/or amplitude), which first optical mask is included in the optical path of the processor. The mask is fixed during assembly of the processor or correlator and a unique pattern is encoded thereon. The software key consists of a pattern defined by a key mask function that is displayed preferably using a spatial light modulator as part of a second optical mask included on the processor optical path. The key mask function is designed to compensate for the wave-front distortion generated by the locking mask function of the first optical mask. Therefore, an optical processor or correlator provided with its unique hardware lock cannot generates useful correlation, unless a corresponding unique software key is used.

Abstract: A phase control circuit sets the phase of a sampling clock signal for A/D conversion of a video signal in order. A binarizing circuit binarizes an analog video signal. A first counter circuit counts the changes of the output signal of the binarizing circuit. An A/D converting circuit digitizes the input signal. A  second counter circuit counts the changes of the most significant bit of the A/D  converting circuit. A subtracting circuit subtracts one from the other of the output signals of the two counter circuits. By changing the phase of the sampling clock signal of the A/D conversion in order within one period, the subtraction results are found, and this process is repeated for one or more periods. Thus the phase of the optimum sampling clock is set according to the subtraction results.

Abstract: A fiber-optic current sensor has a reflection interferometer having a fiber-optic supply lead (2) and a coil-shaped optical sensor fiber (1), the sensor fiber (1) being connected with a first end to the fiber-optic supply lead (2), and being provided at a second, free end with a reflector (10). The fiber-optic supply lead (2) has two fiber arms (20, 21), which interconnect a detector-side and a sensor-side polarization-maintaining coupler (7, 8). A phase modulator (9) for modulating differential phases of two polarized waves propagating in the supply lead fiber (2) is arranged in one of these two fiber arms (20, 21), in which it modulates the differential phase of two waves polarized parallel to one another. Moreover, a means for changing the direction (80) of polarization is present in one of the two fiber arms (20), such that optical waves with orthogonally linear polarizations propagate in a segment (22) of the supply lead fiber (2) adjoining the sensor-side coupler (8). As a result, the advantages of the reflection interferometer can be combined with those of a Sagnac interferometer.

Granted: 2007-09-25
Abstract: A system and method for parallelizing applications of script-driven software tools. Scripts in the software tool scripting (1) language are automatically analyzed (2) in order to produce a specification for a parallel computation (3) plus a set of "script fragments", the combination of which is functionally equivalent to the original script. The computational specification plus the script fragments (4) are then executed by a parallel runtime system (5), which causes multiple instances of the original software tool (6) and/or supplemental programs (7) to be run as parallel processes. The resulting processes will read input data (8) and produce output data (9), performing the same computation as was specified by the original script. The combination of the analyzer (2), runtime (5), original software tool, and supplemental programs will, for a given script and input data, produce the same output data as the original software tool alone, but has the capability of using multiple processors in parallel for substantial improvements in overall "throughput". The invention includes computer program embodiments of an automatic script analyzer.
