Abstract: A system (100) and method for creating three dimensional images using probe molecules is disclosed and described. A sample is mounted on a stage (160). The sample has a plurality of probe molecules. The sample is illuminated with light, causing the probe molecules to luminesce. The probe luminescence can be split into at least four paths corresponding to at least four detection planes corresponding to object planes in the sample. The at least four detection planes are detected via a camera (155). Object planes in corresponding recorded regions of interest are recorded in the camera (155). A signal from the regions of interest is combined into a three dimensional image.

Abstract: A method for minimizing message collision in a device is presented. Two or more overlapping real-time streaming simplex audio messages are received. One of the audio messages is forwarded to be reproduced while the other is stored. Forwarding of the delayed audio message is delayed such that overlapping reproduction of the audio messages is minimized. Reproduction is delayed until a predetermined clock time expires or is dependent on one or more of: the length of the second audio message or the amount of overlap of the first and second audio messages.

Abstract: When, according to the invention, a cleaning head is provided with a hysteresis coupling (9, 11) between the turbine (3) and the gear in the gear housing (13), the gear will remain separated from the turbine and not be subjected to liquid impact. The hysteresis coupling (9, 11) may be adjusted using electromagnets (9) as an inductor, which allows control/regulation of the rotating movements of the cleaning head to achieve the best possible cleaning pattern.

Abstract: A detector circuit is to be used for measuring current by means of substantially identically wound ring core transformers, in which magnetomotive forces are induced by a main current. The magnetomotive forces are counteracted by magnetomotive forces induced by a compensating current. Two of the ring core transformers (2, 3) are magnetized in antiphase by means of a modulation signal. The detector circuit includes optionally a synchronous rectifier for providing an adjusting signal for the compensating current. According to the invention means are provided for compensating for possible differences between the two ring core transformers for the modulation signal. These means include a cornmon winding surrounding the two ring cores (2, 3), said common winding detecting a possible error signal used in a negative feedback loop which automatically seeks to establish an equilibrium.

Abstract: The invention provides a catheter, which can be introduced into the coronary arteries over two or more wires. The catheter can be used for coronary, as well as for peripheral angioplasty, in particular near bifurcations. The catheter is of the rapid-exchange or over-the-wire type. The catheter allows procedures, in which two or more wires are introduced into the different branches of a bifurcation prior to positioning a stent proximal to the bifurcation. The wires are fully functional through the interior passage of the stent after its positioning. The procedure allows angioplasty of the distal vessels of the bifurcation without training or repositioning of the wires. The catheter thus avoids the problem of wire trapping between the stent and the artery wall.

In one aspect, the present invention relates to impairment of the gamma-aminobutyric acid (GABA) receptors in parasitic nematodes, for the purpose of crop protection and/or soil treatment. The invention includes mutated nematode GABA receptor subunits, nematode GABA neuromuscular junction receptor complexes, nucleic acids which encode the mutated and functional receptor complexes, antibodies which selectively bind the GABA receptor complexes and/or subunits, and assays for compounds which adversely affect nematode GABA neuromuscular junction receptor function. The present invention therefore relates broadly to recombinant DNA technology, molecular biology tools, and crop protection and/or soil treatment.

Abstract: The measurement of large DC and AC currents, are measured by a zero-flux current transformer. Two identically wound toroidal cores in which the magnetic flux induced by a primary current is neutralized by a counter-flux induced by a compensation current is passed through a compensation winding (14) common to both cores and having many turns. The compensation current is adjusted by means of an amplifier so that the mean flux in the cores is zero. The intensity of the compensation current is measured by the voltage drop across a measuring resistor.

Abstract: A systemic fungicide and method of application to trees subject to the Dutch elm disease fungus and other fungus diseases wherein the fungicide material used is a water-soluble derivative of methyl-2-benzimidazole carbamate (BCM) and the method of introduction is a positive pressure root injection method. Examples of the water-soluble derivatives are chloride, sulphate, phosphate, nitrate, and sodio derivatives of BCM. The injection method is achieved by severing one or more roots below ground level and applying the fungicide solution to the severed root end under pressure via suitable tubulation.
