A preferred embodiment of a method and apparatus for detection and disablement of an unidentified aerial vehicle (UAV) includes arrays of antenna elements receiving in two modalities (for instance radio frequency (RF) and acoustic modalities, or RF and optical modalities). Signal processing of outputs from multiple antenna arrays locates a potential UAV at specific coordinates within a volume of space under surveillance, and automatically aims video surveillance and a short-range projectile launcher at the UAV, and may automatically fire the projectile launcher to down the UAV.

A scanner for providing a possibility of detecting a surface relief of an object includes a projector configured to guide a light beam in an illumination line over the surface relief to obtain an illuminated location on the surface relief, the projector being further configured to output a projection signal from which a position of the light beam in the illumination line is derivable. Additionally, the scanner includes a collector having a collector micro mirror stimulatable to oscillate in two dimensions and a point-shaped light detector, the collector micro mirror being oscillatingly arranged in a first direction of the illumination line and in a second direction differing from the first direction such that a reflection of the illuminated location within a scan area of the micro scanner mirror is imagable by it onto the point-shaped light detector, and the collector being configured to output a detection signal from which a position of the illuminated location in the first and second directions is derivable.

In an internal combustion engine, an NO_x selective reduction catalyst (15) is arranged in the engine exhaust passage and a urea aqueous solution stored in a urea aqueous solution tank (20) is fed to the NO_x selective reduction catalyst (15) where the NO_x is selectively reduced. Opening and closing of the urea aqueous solution refill port (40) of the urea aqueous solution tank (20) are detected and it is judged if the urea aqueous solution is refilled in the urea aqueous solution tank (20). When it is judged that the NO_x purification rate has fallen to an allowable level or less at the time of engine operation right after the urea aqueous solution is refilled in the urea aqueous solution tank (20), it is judged that the refilled urea aqueous solution is abnormal.

There is provided a liquid tank having a liquid remaining amount sensing module that makes it possible to reliably determine that the amount of ink has reached a predetermined value, in spite of its simple and compact configuration.

A housing of the ink tank is composed of a transparent resin. Infrared light from an external light emitting section is incident on the optical reflector. The reflected light is received by a light receiving section and then, the quantity of light is measured.

A magnetic position detection apparatus includes a substrate, a magnet, a bridge circuit including first through fourth magneto-electric converting elements formed on the substrate, and a detection circuit. A substrate surface is substantially perpendicular to a magnet magnetization direction. The second and third magneto-electric converting elements are, when viewed along the magnet magnetization direction, disposed to be on or in the vicinity of a straight line passing through a center point of a magnetic pole of the magnet and parallel to a straight line perpendicular to both the magnet magnetization direction and the magnetic mobile object. The first and fourth magneto-electric converting elements are disposed so that, when not opposed to the magnetic mobile object, a component of a substrate of a magnetic field to be applied thereto is substantially same as that of a magnetic field to be applied to the second and third magneto-electric converting elements.

A device for identifying the presence of a specific target molecule or biomarker by the detection of a change in an electrical property includes a measurement sensor 8 comprising a semiconducting sensor structure 12 capable of conjugating with the biomarker, thus giving rise to the said change in electrical property, and an electrode system 3, 4 for conducting a signal from the device. According to the invention there is a further such sensor 9, of substantially identical form but having its sensor structure 14 already conjugated with the biomarker, or otherwise capped, e.g. using a further oligonucleotide strand, so as to act as an internal reference. When a biological sample, e.g. saliva, is applied to the electrodes, the reference enables the discounting of all environmental effects other than the biomarker. The invention provides a simple, cheap and accurate text for one or more biomarkers that can be used in the field without complex equipment.

A process for detecting electrostatic charges on a wafer surface during the fabrication of semiconductor devices after the wafer is subject to a de-ionized water rinsing step to remove particles and other impurities from a wafer surface. This process includes the steps of: (a) positioning an insulation layer above a wafer surface on which electrostatic charge densities are to be scanned; (b) using a movable probe to measure voltages at various locations at the insulating layer; (c) collecting the measured voltage distribution; and (d) examining the collected voltage distribution to identify areas on the wafer surface correspondingly to high electrostatic charge density. Because high precision and high resolution scanning can be made with this method, trouble-shooting diagnosis to be expeditiously performed with minimum interruptions to the semiconductor fabrication operation.

In a load driving circuit, a detection current Is (=Io/N), 1/N of a driving current Io, flows in a detection resistor, where N indicates a shunt ratio between a current (=driving current Io) that flows in an output source (S1) and a current (=detection current Is) that flows in a detection source (S2). The shunt ratio is determined by a cell ratio between the output source (S1) and the detection source (S2).
