Title: System and method for simulating user interference received by subscriber units in a spread spectrum communication network
Inventor: SOLIMAN SAMIR S
IPC: H04W52/34
Filed: 1995-07-05
Abstract: A method and apparatus for simulating signal interference within a communication system, such wireless or cellular communication systems. The communication system is preferably of a type in which code division multiple access (CDMA) spread spectrum communication signals are used. The method for simulating signal interference power received by a base station receiver includes estimating a first composite signal power corresponding to the sum of signal power transmitted by a first set of simulated users located in a first cell. An estimate is also made of a first normalized date rate for transmission of the composite signal. A first interference signal is then generated at a power level determined on the basis of the first composite signal power and normalized data rate. In a preferred implementation, the first interference signal power is adjusted in accordance with an average power fluctuation arising as a consequence of closed loop power control. Further, a second composite signal power is determined by estimating the sum of signal power transmitted by a second set of simulated users located outside of the first cell. A similar estimate is made of a second normalized data rate at which this signal power is transmitted by the second set of simulated users. This allows the generation of a second interference signal based on the second composite signal power and normalized data rate. Generation of the first interference signal will typically involve synthesis of electrical noise over a predetermined frequency band. The power of the electrical noise is then adjusted in accordance with the product of the first composite signal power and the first normalized data rate.

Title: Paintings

Granted: 1990-06-13
Abstract: Basic pictorial content is provided on a uniform dark (e.g. black) coloured varnish surface of a support board 10 by application of a lighter (e.g. white) coloured base layer 12. It is important that the surface of the board 10 should be embossed so as to have a grained appearance, preferably resembling leather. Translucent colour washes 20,30,40 50(e.g. red, blue, yellow) are subsequently applied over all or only part of the board surface for the purpose of colouring in the plain base layer in any manner desired by the end user. No great care is required in application of these colour washes; it is expected that they will overlap onto the remaining dark varnish coating, but due to the dark, glossy and grained nature of this area the regions covered by the washes and particularly their edges are not visible. Moreover, as the surface is glossy and does not immediately absorb the wash errors can readily be put right.

Title: Method for preparing tinted contact lens
Inventor: FORD JAMES D
IPC: C09B5/44
Filed: 1993-10-26
Abstract: An improved method is disclosed for imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is a water-soluble halotriazine dye. The dye is reacted with a hydrophilic monomer to prepare a reactive dye containing predominantly monofunctionality. The monomer is then subjected to polymerization in the presence of a homogeneous solution of the reactive dye in the monomer under conditions to yield the hydrophilic polymer from which the lens is formed. The dye becomes bonded to the polymer during polymerization. The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens. Furthermore, the lens does not need to be washed with aqueous base to bond the dye to the lens.
