Abstract: A holiday ornament is attachable to a relatively soft candle in such a fashion that it is firmly held to the candle until the candle burns down far enough to permit the ornament to fall off. A metal strip is welded to the back of the ornament. The two opposite ends of the strip are bent upwardly, away from the soldered portion and disposed at an angle of approximately 10-15° so that, when pushed into the candle, the soft wax exerts a force on the two pins in order to keep it in place during normal use. The structure of the pins keeps the ornament in the vertical position until the candle has burned down at least half way, at which point the ornament falls off for lack of support. Thereafter, the ornament can be removed and placed on a holiday item, such as a Christmas Tree, wreath, etc.

Abstract: An electrical connector terminal includes a planar wire connecting portion formed to connect with an outside wire lead, the connecting portion defining a first plane. A shoulder portion of the terminal has a planar first section extending from a first side of the connecting portion, and the first section defines a second plane that is normal to the first plane of the connecting portion so that the terminal is held stable when mounted on a wiring board and the first section of the shoulder portion is restrained by an outside part located out of the first plane of the wire connecting portion. An elongated mounting portion or tail is formed to fit axially in a terminal opening in the wiring board. The tail is joined to a free end of the first section of the shoulder portion remote from the wire connecting portion, and the second plane of the first section includes the axis of the mounting portion.

Abstract: In order to extend the available spectral range and to optimize spectral resolution while retaining a compact spectrometer setup, two diffraction gratings are operated with congruent focal curves in a Paschen-Runge geometry. The spectrometer features only one entrance slit and allows an adequate adaptation of the covered spectral range to the demands of analytical spectrometry. Apart from photomultiplier tubes commercial solid-state linear array sensors placed tangential at the Rowland circle are used for simultaneous detection of the spectrum. By employing angular cut cylindrical mirrors the radiation is deflected by 90% upward or downward in an alternating series. In this way two effects are achieved, an almost complete detection of the spectrum firstly and secondly a gain of intensity by focusing of radiation perpendicular to the plane of dispersion.

Abstract: A programmable apparatus for laser beam shaping including a preprogrammable mircomirror array produces a spatial energy distribution suitable for accurately and rapidly marking, machining and processing materials. The preprogrammed micromirror array redistributes the laser output beam energy to produce a desired two-dimensional machining pattern on a work piece. The energy pattern created by the preprogrammed micromirror array is changeable between successive pulses of the laser to create accurate, complex three-dimensional machined shapes in a work piece not easily achieved by conventional machining systems. A special application of this invention is laser beam shaping to produce a uniform spatial energy distribution, i.e. homogenizing the beam from a laser with non-uniform energy distribution. Continuous adjustment of beam shaping is provided to maintain beam homogenization in accordance with changes in laser beam output energy profile.

Abstract: A laser machining device is capable of simultaneously machining two- or three dimentional patterns on the surface of a workpiece. A micromirror array positioned within a laser cavity generates a patterned plurality of laser beamlets which can be homogenized and deflected by a second micromirror array onto the surface of a workpiece to create a two-dimensional pattern. Alternatively, the second micromirror array can deflect laser beamlets of unequal energy density to produce a three-dimensional pattern.

Abstract: A microwave antenna is described, capable of simultaneous maximum gain communication with N≧2 satellites in geo-stationary orbit. The orbiting satellites are positioned offset relative to each other at a specific azimuth angle(s) &phgr;. The microwave antenna has radiating elements that are divided into N groups (1a, 1b; 1a′, 1b′; 1a″, 1b″ 1c″) of radiating elements. The antenna is characterized by the fact that each of the N groups of radiating elements is organized in a plane, with the planes arranged at specific angles relative to one another corresponding to the respective azimuth offset angle of the satellite to be communicated with, such that the surface normal (FN) of the planes, once the microwave antenna is oriented, point in the direction of the respective satellites.

Abstract: A surgically implantable radioactive wrap is positioned around the wall of a body vessel, duct or passageway to maintain patency of these structures by mitigating overexuberant cellular proliferation. Such excessive cellular growth may occur as the result of a disease process or following a trauma or an intentional surgical or intravascular intervention. The device provides for delivery of ionizing radiation to a localized target tissue site. Integral design features provide for the shielding of non-targeted tissues and for the attachment of the device to the target tissue structure. A radiation attenuation element serves to absorb extraneous low-energy electrons incidentally emitted by the treatment source and provides for a more uniform radiation dose distribution through the full thickness of the target tissues. The wrap can be easily applied with minimal handling and with limited radiation exposure to operating personnel.

Abstract: In a semiconductor p-i-n photodiode an undoped absorption region (10) is epitaxially grown between two highly doped regions (14, 16). In prior art lattice matched InGaAs p-i-n photodiodes current epitaxial structures use low InP cap (16) doping (n˜2.5−6×1016/cm3), and nominally undoped (not intentionally doped, n˜1×1013−5×1014/cm3) InGaAs absorption regions (10). The shunt resistances of p-i-n photodiodes according to the present invention with intentional doping between n˜5×1017/cm3 and 1×1014/cm3, in the InGaAs absorption region (52, 60) are significantly increased over that of a standard structure (non-intentionally doped).

A camera-based feedback loop can be employed to fine-tune the optical blending by digitally altering the image source.

Abstract: A method for making accurate and precise customized corrections to the surface of an optical lens is described. An electronic correction contour is generated from a measured refractive correction for a patient, and transferred to the surface of the lens by ablation etching with one or more laser pulses. After each of the laser pulses, the refractive properties of the lens are measured and compared to the electronic contour correction derived from a patient's refractive correction. The ablation etching is terminated in localized areas where the refractive properties match the electronic correction contour. End point detection includes monitoring refractive qualities of the lens during the recontouring process, modifying the pattern through changes in the laser pulses.

The invention is realized with a typical high-speed cable having a connector provided with a dissipative medium and at least one conductive pad. Static electricity on the jacket material of the cable induces a charge in the cable wires, which is bled to the pads via the dissipative medium. The charge on the pad is then grounded prior to or as the cable is connected to a cable jack.
