Abstract: A pseudo noise generator includes a first arbitrary random number generator that generates two groups of first random number signals respectively corresponding to pre-divided Amplitude Probability Distributions, which are obtained by pre-dividing a specified Amplitude Probability Distribution into two parts at a specified level. A second arbitrary random number generator generates two groups of second random number signals respectively defined by a specified Pulse Duration Distribution and a specified Pulse Spacing Distribution at said specified level. One of the two groups of first random number signals are selected in accordance with the specified Pulse Duration Distribution and the specified Pulse Spacing Distribution defined at said specified level. The selected signals are converted, by a D/A converter, to pseudo noise of analog value in accordance with the Amplitude Probability Distribution, the specified Pulse Duration Distribution and the specified Pulse Spacing Distribution at the specified level.

Abstract: The invention refers to the methods and means of conversion of electromagnetic radiation (mainly belonging to the optical range) with the purpose of forming of objects' images (mainly of spatially extended ones) within incoherent light. In an Optical System (OS) the following procedures are being performed: pre-defined distortion of optical motion of rays by means of Amplitude-Phase Mask (APM); optical-electronic conversion of distorted image of object 6 and deduction of the distortions inserted by the APM and by OS. Deduction of distortions is arranged by means of accorded spatial filtration of the distorted image. Distortion of optical motion of rays is accomplished in the direction that is close to the orthogonal one in regards to the distortions brought in by defocusing and by aberrations of the OS. In the meanwhile, the possibility to receive the function of distortions that possesses rotary symmetry is being secured.

Abstract: A device for cleaning jewelry and the like has a housing with an electro-cleaning part and a steam cleaning part. A cleaning bath tank is made of an electrically conductive material. The tank is supported in the electro-cleaning part and can be connected to an electric potential and filled with a conductive fluid that cleans more effectively when heated. The jewelry cleaning device also has an electrical conductor extending into the tank, one that is electrically insulated from the tank and can be connected to an electric potential. There can be placed into the tank an insert with a support surface and conductive engagement means supported so that jewelry engages in an electrically conductive way with the insert.

Abstract: An adjustable utility light for suspension from an object has a nominal width and lateral edges, and both an elongate hollow member with opposing open ends and an axis. A pair of generally elongate gripping members is also present, each with a free gripping end and a hollow member engaging end. The gripping members are slidably and rotatably mounted with regard to associated open ends of the hollow member so as to be able to change the axial distance between the gripping members. An elongate biasing member extends through the hollow member and is attached at opposite ends to the gripping member. The biasing member is generally under tension so as to urge the gripping members towards each other, minimizing the distance between them. It is stretchable upon separation along the axis of the gripping members against its own biasing forces. An elongate lamp is provided with an axial length generally equal to the nominal width of the hollow member.
