| 20100182601 | OFFSET ILLUMINATION APERTURE FOR OPTICAL NAVIGATION INPUT DEVICE - An optical navigation input device with an offset imaging aperture. The optical navigation input device includes a light source, an illumination aperture structure, and an image sensor. The light source directs a light beam toward a substantially specular illumination surface. Scattered light reflects off of a surface reflection feature along a scattered light path which is offset from a specular reflection path. The illumination aperture structure at least partially defines an illumination aperture interposed between the light source and the illumination surface. The illumination aperture produces a diffraction pattern that includes a diffraction discontinuity which is substantially free from diffracted light within a sector area outside of the light beam. The image sensor is disposed within the scattered light path at a location corresponding to the diffraction discontinuity. The image sensor receives the scattered light from the surface reflection feature and generates a navigation image of the surface reflection feature. | 07-22-2010 |

The flex circuit, printed circuit or printed circuit board terminals are spaced apart from, or placed in physical contact with, corresponding ones of the touchscreen electrode terminals, but are not soldered or otherwise physically attached to the touchscreen electrode terminals by conventional electrical connection bonding materials or agents such as anisotropic conductive film or solder. The flex circuit, printed circuit or printed circuit board terminals are positioned with respect to the touchscreen electrode terminals such that the flex circuit, printed circuit or printed circuit board terminals are spaced part from, or in physical contact with, the touchscreen electrode terminals by gaps ranging between about 0.0 mm and about 1 mm. The gaps are sufficiently small to permit capacitive coupling of drive and sense signals provided by the touchscreen electrode terminals to the flex circuit, printed circuit or printed circuit board terminals. | 05-03-2012 |

| 20080214258 | Wins of Restricted Credits in a Gaming Machine - Disclosed is a gaming system and method designed or configured to provide wins of restricted credits. Restricted credits may be awarded according to the same or a different pay table than cashable credits on the same machine or at the same gaming property. Where separate pay tables are used for restricted and cashable credits, the invention may be implemented with a machine that accepts and pays only restricted credit according to a single, fixed internal payout schedule (“pay table”). Alternatively, the invention may be implemented with a machine that pays restricted credit according to one fixed internal pay table and cashable credit according to another fixed internal pay table. Or, a machine may pay restricted credit according to an external pay table provided by a host system to which the machine is connected. | 09-04-2008 |
| 20090036190 | Game Result Graphical Verification on Remote Clients - Methods an apparatus are described for verifying a game of chance is displayed correctly on a remote client. The verification may include storing game history information associated with a game of chance presented at a remote client. The server can provide a game outcome associated with the game of chance, and the game outcome can be presented visually on the remote client. A sample game outcome can be generated on a remote client and a user may be asked one or more questions about the sample game outcome to verify that the sample game outcome is correctly displayed on the remote client. In addition, the remote client can then generate a hash of the 1 game outcome and send the hash to the server. The server can store the client-generated hash and game history. If a dispute arises, this client-generated hash can be compared to a server-generated hash. A comparison of these hashes can be used to verify that the correct outcome was displayed on the remote client. | 02-05-2009 |
| 20090054149 | MULTIPLE MONETARY TYPE GAMING MACHINE WITH CASH CONVERSION FUNCTIONALITY - A gaming machine connected in a gaming network or operating as a stand-alone machine, is capable of accepting two or more currencies for wager game play.
