A touch screen panel includes first and second sense cells on a same layer and coupling patterns that couple adjacent ones of the first sense cells and adjacent ones of the second sense cells to each other, respectively. The coupling patterns do not cross with each other, thereby improving the ability of the coupling patterns to withstand static electricity. A dummy line formed of a same material as the sense cells may be formed between the first and second sense cells, and the dummy line is electrically coupled to a guard ring located in an area outside of a display area of the touch screen panel, making it possible to overcome the effects of static electricity applied to the front surface of the touch screen panel as well as the side surface thereof.

An above-water system provides automatic alerting for possible drowning victims in swimming pools or the like. One or more electro-optical sensors are placed above the pool surface. Sequences of images are digitized and analyzed electronically to determine whether there are humans within the image, and whether such humans are moving in a manner that would suggest drowning. Effects due to glint, refraction, and variations in light, are offset automatically by the system. If a potential drowning incident is detected, the system produces an alarm sound, and / or a warning display, so that an operator can determine whether action must be taken.

A transistor includes one or more channel taps containing a stack consisting at least in part of a semiconductor an interfacial III-VI layered compound and a conductor. The III-VI compound consists primarily of atoms from Groups IIIA-B and from Group VIA of the Periodic Table of the Elements in an approximate 1:1 ratio. These materials may be formed as layers of covalently bonded elements from Groups IIIA-B and covalently bonded Group VIA elements, adjacent and respective planes of which may be bonded by Van der Waals forces (e.g., to form a single bilayer consisting of a single plane of atoms from Groups IIIA-B and a single plane of Group VIA atoms). One particular III-VI material from which the interfacial layer is made, especially for p-channel transistors, is GaSe. Other III-VI compounds, whether pure compounds or alloys of pure compounds, may also be used.

An optical based identification system that is easily deployable and can be used in broad daylight. Fluorescent semiconductor nanocrystals (quantum dots) that fluoresce at specific wavelengths are distributed in a suitable polymer. The resulting mixture can then be applied as paint or on an adhesive label for application to a portion of any equipment or member of a friendly unit. The system also has a corresponding detectional processing unit which may be mounted on ordnance or on any other equipment such as aircraft. The detection unit uses a laser, which when active, causes a laser beam to strike the paint or adhesive able applied to the friendly unit. This causes the quantum dots to fluoresce. The fluorescence of the quantum dots can be detected by the sensor portion of the detection / processing unit. The sensor portion then transmits the data generated by the detected fluorescence to a data processing portion detection / processing unit such as a corresponding signal to the equipment operator or, if the unit is mounted on ordnance that has been launched to the warhead to deactivate the warhead. To overcome the effects of broad daylight on an optical system, the quantum dots can be detected by the sensor portions of the detection / processing unit. The sensor portion then transmits the data generated by the detected fluorescence to a data processing portion which decodes the data. If the decoded data indicates a friendly unit, the detection / processing unit sends a corresponding signal to the equipment operator or, if the unit is mounted on ordnance that has been launched to the warhead to deactivate the warhead. To overcome the effects of broad daylight on an optical system, the quantum dots are engineered to fluoresce at wavelengths corresponding to the absorption lines of the solar spectrum, more commonly known as Fraunhofer lines.

The present invention provides a method and apparatus for optical spectral power monitoring that employ a time-division-multiplexed detection scheme. The optical spectral power monitoring apparatus of the present invention uses a wavelength-dispersing means such as a diffraction grating to separate a multi-wavelength optical signal into multiple spectral channels and an array of beam-manipulating elements positioned to correspond with the spectral channels. The beam-manipulating elements are individually controllable so as to direct the spectral channels into an optical detector in a time-division-multiplexed sequence. The optical spectral power monitoring apparatus may further employ a polarization diversity scheme, thereby becoming polarization insensitive. This enables the apparatus of the present invention to enhance spectral resolution, while providing improved accuracy in optical spectral power detection. Accordingly, a variety of novel optical spectral power monitors can be constructed according to the present invention, that are well suitable for WDM optical networking applications.

This invention teaches a rope that can be electrified. The rope is comprised of an outer sheath and an inner core. The outer sheath includes non-conductive elements braided with one or more conductive elements. The conductive elements are wound in a parallel helical pattern and do not touch each other.
