Title: Method for the design of multifocal optical elements
Inventor: RUBINSTEIN JACOB
IPC: G02C7/02
Filed: 2000-02-08
Abstract: A method for designing a surface of a multifocal optical element, such as a progressive spectacle lens, includes the steps of partitioning a region into triangles, (~i) defining a set of functions, each representing a portion of the surface (li) over one of the triangles (~i), and optimizing the functions.  A further embodiment includes the steps of partitioning a region into polygons (200), and defining a set of functions, each representing a portion of the surface over one of the polygons (202). Continuity constraints for values of the functions and values for the first derivatives of the functions at boundaries of the polygons are dictated. Continuity constraints for values of the second derivatives of the functions at boundaries of the polygons are not required. The functions are optimized subject to the dictated continuity constraints.

Title: Two-axis ball-based cursor control with tactile feedback
Inventor: YU YAT SHUN DAMIEN
IPC: G06F3/0354
Filed: 2001-01-29
Abstract: A two-axis ball-based cursor control apparatus with tactile feeling is provided, which includes a housing; a spherical ball contained partially within the housing and having a plurality of recesses distributed about its outer surface; two pairs of spring biased sensor mechanisms each including a probe, a spring, and a transducer;  and a means for processing the signals received from the sensor mechanisms. Each of the four probes is positioned so that it rests within one of the recesses on the spherical ball when the ball is stationary. As the ball is rotated, the probes are pushed up and out of the recesses by the ball, causing the corresponding springs to alternately compress and decompress, before the probes come to rest in adjacent recesses. Each transducer generates an electrical signal corresponding to the rate of compression and decompression in the corresponding spring. The signal processing means then translates the signals from each of the transducers into movement of a cursor on an electronic display screen which corresponds to the rotation of the spherical ball about each of its axes.

Title: Gas and energy generation system
Inventor: GORDON RAYMOND H
IPC: F23G5/00
Filed: 2001-03-07
Abstract: This invention was developed to change a faulty system of using landfills for waste or just moving it from place to place without solving a growing problem. This invention takes any waste material and processes it all by combining several known technologies that work in concert to process the entire waste into usable commodities.      The energy derived from municipal solid waste that includes almost every combustible material there is and a certain amount of non-combustibles. The combustibles are converted to gases and the ash residue, that is composed of ash, carbon and non-combustibles, is diverted to a separate chamber where it is vitrilized with a plasma torch and the molten material is poured into molds to make unleachable flag stones or it can be crushed into filler material for asphalt, concrete or used as road bed material.      The gases are burned at a high temperature, which destroys all the smoke and other pollutants. The heat derived therefrom is channeled through a heat exchanger and steam boiler to power a turbine that in turn drives a generator or alternator to generate electricity. The electricity powers the fans, pumps, compressors and motors for the material handling throughout the entire system. The waste heat from the turbine is diverted to the thermophilic digesters that stimulates the production of enzymes to digest sewage leaving only irrigation water or in cases where water is scarce it too can be treated and recycled or made potable.      The Thermophilic digester uses the waste heat from the turbine and any fumes that are emitted by the sewage digester are drawn into the after burner of the gas generator or that smelly air can first be used to aerate the sewage to provide oxygen to enhance bacterial action. It is injected into perforated pipes in the sewage tanks where it not only aerates the sludge but simultaneously, convectively circulates the said sludge, eliminating the need of a mechanical paddle system.      In the event the waste contains any heavy metals it is melted in the plasma oven and becomes imbedded in unleachable flagstones, asphalt or concrete.      The invention provides a safe and economic method to recycle waste to energy without polluting the air, land or groundwater's.

Title: Intracavity frequency-doubled diode-pumped laser
Inventor: BEILSCHMIDT RENE
IPC: H01S3/081
Filed: 2000-09-09
Abstract: The invention relates to an intracavity frequency-doubled diode-pumped laser . The aim of the invention is to provide a simple and inexpensive means with which interfering capacity variations of the laser radiation produced by mea ns of the non-linear optical crystal at the beginning of the capacity adjustmen t can be avoided while at the same time preventing capacity-reducing elements in the resonator and thermal effects from having negative effects on the laser behavior. To this end, the laser contains a solid body as the laser-active medium which has a temperature gradient that is substantially parallel to th e resonator axis. The laser radiation of a laser fundamental wave length is converted to a laser radiation of another wave length by means of a non-line ar optical crystal with a lower effectiveness than required for obtaining the maximum capacity of the converted laser radiation. The inventive laser is especially useful for medical purposes, for example in the field of ophthalmology for coagulating the retina, but also in the field of dermatolo gy.
