Abstract: Six steps of varying height are provided adjacent to one another in an integrated unit resting upon and surrounded by a floor surface. The height of each step in relation to its adjacent steps, and in relation to the floor, is determined such that by stepping between any chosen pair of adjacent steps, or by stepping between the floor and any given single step, step height differentials of approximately 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and optionally 26 inches are all made available to the user.

Abstract: A Bulk Mail Container (BMC) unloader uses a simple crossed four bar-linkage to move a predetermined point on a BMC unloader in a substantially straight line while the overall BMC unloader rotates about that predetermined point so as to upend the BMC container. This takes advantage of the crossed four-bar's substantially straight-line motion over a limited range of its motion, as well as the rotational motion of the particular unloader link disclosed herein. This is advantageous for unloading. In use, a BMC container is simply rolled into the BMC unloader, and the entire combination of the BMC container and BMC unloader is then actuated to produce substantially straight line motion along a suitably selected “center” point of the BMC unloader while the overall combination rotates about the center point so as to upend the BMC for unloading.

Abstract: A fishing lure comprising a crankbait or similar body member to which both a spinner and a hook are attached, provides the crankbait with a realistic swimming motion. In particular, the spinning of the spinner, coupled with its positioning on the crankbait, imparts an oscillating, swimming-like motion to the crankbait, which greatly enhances the luring of fish. This is in addition to the benefits already derived by virtue of the spinning of the spinner.

Abstract: A microelectromechanical power relay uses mercury, or a similar liquid metal with high surface tension, as a flexible non-degrading contact mechanism. The basic systematic requirements for the micro-relay include large current carrying capacity, high speed, use of control voltages readily available in the given application, and an acceptable hold-off voltage. The preferred embodiment of the present invention includes the novel configuration of a liquid metal current carrying switching device.

Abstract: A telescopic firearm scope/sight which is fully integrated with a compact digital camera, and which has size, shape and weight characteristics that are substantially the same as those of a conventional, camera-less telescopic scope, is used to photograph a target proximate the instant at which the target is fired upon. To configure the weapon for photography and firing, the scope is simply placed on the firearm in the same manner as a conventional scope, and the firearm is then fired in the conventional manner. Photographs are recorded, alternatively, in response to the sound of, or the recoil from, the firearm firing. An alternative embodiment eliminates the telescopic sight, but maintains all of the digital photography components, and is particularly useful for smaller-scale firearms such as pistols.

Abstract: A pleated microwave oven liner comprising a plurality of liner pleats, is expandable in the preferred embodiment from initial dimensions of approximately 6 inches in height by 11 inches in width, to final dimensions as large as approximately 15 inches in height by 21 inches in width, by ⅛ inch increments. This microwave oven liner, by virtue of its resizability (scalability), can be used to protect a wide range of sizes of microwave oven from spills and spatters associated with the microwave cooking and heating process.

Abstract: A method and apparatus for unified overlay dialing enables simplified telephone dialing to occur within a standard overlay area and eliminates disruption dealing with area code saturation. Each three-digit area code within an overlay area is associated with a single-digit suffix, with the parent area code obtaining the suffix “0”. Intra-overlay area dialing then proceeds on the basis of a seven digit number plus a one-digit suffix, rather than a full 10 or 1+10-digit number. For dialing to the parent area code from within the overlay area, the suffix may be omitted entirely, and the expiration of a suitable timing delay causes the seven digit number provided to be dialed into the original (parent) area code. This method can be implemented in connection with a telephone company central office switch, a modified custom calling service or be made accessible to individual telephone subscribers using computerized customer premises equipment.

Abstract: An improved optical pressure sensor determines the pressure of the fluid to be monitored by the deflection of a diaphragm in the pressure chamber of the sensor which has an inlet from the measured vessel. The deflection of the diaphragm is determined by monitoring the interference of diode light reflected from the diaphragm and a silicon grating structure superimposed over the diaphragm, at critical positions. Intensity detectors are placed at critical positions such as the specific orders of the diffraction grating to measure the interference intensity of the reflected light. The interferometric accuracy with which the pressure measurement is made with the present invention far exceeds that obtained with optical pressure sensors described in the prior art.

Abstract: An improved microsystems testing and characterization system which allows the system user to identify specific structures, and thereby to initiate an automated testing sequence to be applied to that structure or a series of structures. The integrated control system that governs the present invention automates the power supply to the device, the precision motion control of all components, the sensor operation, data processing and data presentation. Therefore operation is autonomous once the microstructure is in place and the testing sequence is specified. The integrated testing system can be used to perform tests on an entire wafer or on a single die.

Abstract: A device, system and method permitting on-line explosives-based cleaning and deslagging of a fuel burning facility such as a boiler, furnace, incinerator, or scrubber. A coolant, such as ordinary water, is delivered to the explosives to prevent them from detonating due to the heat of the on-line facility. Thus, controlled, appropriately-timed detonation can be initiated as desired, and boiler scale and slag is removed without the need to shut down or cool down the facility.

Abstract: An improved tunable diode laser is capable of fast digital line selection over a broad wavelength spectrum, and uses no moving parts. A focusing element, such as a mirror or a lens, used in combination with a micromirror array serves as the retroreflector in a typical Littman-Metcalf laser cavity. This configuration provides arbitrary, simultaneous, and/or sequential line selection capability over a very broad wavelength range. The use of an individually-controllable micromirror array eliminates the high precision mechanical motion of a grating element and improves the overall durability and ruggedness of the device. The present invention can be integrated into any diode laser and has significant application in spectroscopy.

The improvement/refinement method repeatedly searching, for consecutive sets of active target elements to be refined or improved, an associated submesh and set of terminal edges, the searching process not modifying the mesh data structure; then according to the point insertion method chosen, selection of the point or the points to be inserted between the midpoints of the terminal edges modified by some boundary considerations; inserting the selected point or points in the initial mesh; and then proceeding to the succeeding set of active target elements until an user-defined stopping criterion is achieved.

Abstract: To preserve flowers and provide aromatherapy, low temperature paraffin is heated to a liquid state of approximately 130 degrees Fahrenheit. A floral nutrient and preservative such as sugar is then added to the low temperature paraffin. Optionally, scents and/or color dyes are also added. The heads of flowers to be preserved are then dipped in this paraffin mixture for one to three seconds and thereafter allowed to dry. The flower can then be used immediately, or optionally hung upside down for one to three weeks prior to use to further improve shelf life.

Abstract: An apparatus and method disclosed herein can be utilized in all DMA-based optical systems, such as imaging and projection devices, in order to improve light efficiency and brightness by a significant factor and maintain good contrast. This feature is especially important in night vision systems and other low light applications. A means is provided of masking a designated area of light collected by the system objective lens in order to eliminate light collected from “flat” or “off” state micromirrors that would degrade the image quality produced. The masked objective lens, with a larger aperture, enhances the light collection from micromirrors in the “on” state only.
