Abstract: Method of processing primary game outcomes in order to determine a prize in an auxiliary game comprising: establishing a first class of outcomes associated with a credit event, a second class of outcomes associated with a no-credit event, a third class of outcomes associated with a non-event hold and a fourth class of outcomes associated with a tradable event in the auxiliary game; monitoring the credit events over a predetermined number of past events in said auxiliary game and awarding at least one prize when at least one of the predetermined numbers or configurations of credits occur. The method further allows the player to exchange tradable events for credit or no-credit events. This invention allows a plurality of primary games to share a common auxiliary game and balances, for each primary games, the chances of winning a prize in the auxiliary game.

Abstract: The contact lens has a fused construction with improved comfort, reduced optical distortions, such as halos, reduced discontinuities, and improved mechanical stability. The lens has an inside portion extending from a periphery of the lens over a concave side of the lens, and a second central exterior portion fused to the first portion. A central zone provides a first optic power and a first concentric band providing a second optic power. A central interface between the first and second portions has a curvature substantially the same as a curvature of the concave side. The second portion forms a junction with the first portion on a convex side of the lens substantially outside of a field of view of a user's eye. A transition profile between the junction and the central interface determines, along with the first and the second indices of refraction, the second optic power.

Abstract: A method for playing a poker game along with an auxiliary game, which depends on the poker game outcomes, is provided. The outcomes of the poker game are divided in three categories: credit events, no-credit events and non-event holds. Depending on their categories, outcomes influence the auxiliary game in different ways. The preferred way the auxiliary game works is by monitoring credit and no-credit events with a time window having neither a beginning nor an end; the amount of information monitored being constant. When a predetermined number of credits is accumulated within the monitoring window, an auxiliary prize is awarded. The invention also provides ways to display the information monitored by the auxiliary game so that this information is easy for players to understand and to follow. Accordingly, the invention provides an enhanced play experience that maintains excitement.

Abstract: Two variations of a continuous-time instantaneous companding filter are integrated in a 25 GHz bipolar process. Their −3 dB frequencies are tunable in the ranges of 1-30 MHz and 30-100 MHz. The dc gains are controllable up to 10 dB. The measured dynamic ranges for a 1% total harmonic distorsion are 62.5 dB and 50 dB, for the 30 MHz and 100 MHz filters respectively. At maximum cutoff frequencies, the filters dissipate 6.5 mW from a 1.2 V supply. The filters are simple, common-mode interference-resistant, class AB log-domain integrators, suitable for implementation in low-cost bipolar processes. They are suitable for realizing low-voltage filters with reasonable linearity and signal-to-noise ratio. ALL-NPN low distortion input and output interface stages can be added to the integrators. The filters can be used to realized high-frequency programmable filters.

Abstract: For analyzing micro-organisms and other high-molecular weight species, a sample of the substance to be analyzed is prepared, placed in a pyrolyzer where it is pyrolyzed with a selected temperature program to provide pyrolyzed product of a high-dalton mass range. The product is ionized using metastable atoms which results in efficient ionization with little fragmentation. The metastable atoms are generated using a generator that provides a beam of metastable atoms which is basically free from ions. The ionized product is then analyzed using a high acquisition rate mass analyzer, such as a time-of-flight (TOF) analyzer.

Abstract: The present invention comprises an apparatus and a method of microscopy, for measuring depth dependent profiles of optical absorption, photoluminescence and light scattering in thin films on length scales of a few micrometers to a several millimeters. The principles of this invention are also directly extendable to imaging absorption and scattering at other wavelengths, and the scattering of electrons, and neutrons in thin films on the same or shorter length scales. In the optical range, this depth profile information is recovered by the direct recording of micrometer scale images of a light beam propagating along the depth axis of the material under study. The recording is implemented using a crossed beam microscope apparatus in which a collimated optical beam from a light source is propagated through the material under test.
