A modular laser objective for use with a microscope is provided. A mounting modular body permits the modular objective to be releasably mounted to the turret of a microscope. The objective has an optical axis that permits an image beam to be emitted through the objective toward the eyepiece of a microscope. The modular body supports a mirror positioned at an angle to the optical axis of the objective. A modular laser assembly is mounted on the modular body on a first side of the mirror for directing a laser beam toward the mirror so that the energy is reflected off the mirror and through the objective in a direction that is substantially aligned with the optical axis of the objective. A modular indicator assembly is received in the modular body and includes a source of light positioned with the light incident on the other side of the mirror to reflect a beam of light in a direction opposite to the direction of the laser beam to provide an optical representation at the eyepiece of a microscope or on a camera of the position on the target of the laser beam being emitted by the objective.

A method and apparatus for detecting a channel jammed by narrowband jamming interference in a block oriented digital transmission system such as an orthogonal frequency division multiplexing (OFDM) or discrete multi-tone (DMT) system. A spectrum of a received data bearing signal is examined to identify areas of the spectrum that are likely corrupted by a narrowband jamming interference. The method identifies jammed channels by applying a boxcar filter, in order to identify narrow peaks in the spectrum that are substantially larger in magnitude than adjacent channels. Channels identified as jammed or affected by a jamming signal, are listed in a jam mask used for screening out corrupted channels during data transmission.

The present invention relates generally to the provision of robust telecommunication to and from remote areas without reliably operating infrastructure such as electrical distribution power grid, telephone networks, and the like using a novel combination of equipment with a reduced data set and transmission protocols. The invention may be used in remote areas by lightly trained personnel or may be connected to remote unmanned sensors, and permits the collection of data from the field and the communication of signals back to the field.

A method for calculating and displaying the isothermal contours of the energy produced by a laser in a sample includes applying a laser beam to the focal point of a sample. The region near the focal point is divided into cylinders coaxial with the beam. The maximum temperature reached during the laser pulse of at least three points at arbitrary distances from the focal point is derived. The temperatures calculated are plotted as a function of distance from the focal point sufficient to generate isothermal contours. A computer display is then generated of the isothermal contours corresponding to the temperature calculations.

A lighting apparatus includes a first source of monochromatic light, a second source of white light, and a third source of polychromatic light. The light from the three sources combine to produce a resultant color of light from the apparatus. The intensities of the light emitted by the first, second and third sources are independently controlled by a controller to produce a desired resultant color of light. Varying the amount of electric current applied to each such light source by substantially an equal amounts to changes the luminance of the combined light with out affecting the resultant color. The lighting apparatus can be operated to replicate a Planckian radiator with a color rendering index of at least 80 throughout a substantial portion of the visible light spectrum produced by the lighting apparatus.

A power converter for converting DC to AC power or DC to DC power includes an input circuit, a transformer, an output circuit, and a controller. The input circuit receives DC input power and creates high frequency pulses. The transformer transforms the high frequency pulses into at least two sets of transformed pulses, the sets of transformed pulses having alternating and opposite polarity. The transformer includes a primary winding and a secondary winding, where the primary winding is connected to the input circuit. The output circuit includes a plurality of switches for providing a full wave rectified or DC output, where the output circuit is connected to the secondary winding. The controller controls the switches to provide a continuous current path through the output circuit thus minimizing voltage spikes and ripple, and greatly reducing the cost and complexity of the output circuit usually required to handle these spikes and ripple. In addition, this provides for lagging currents typical of an inductive load and provides for clean zero crossing of the AC output wave.
