20110118017 | Electronic Gaming Device with a Light-effect Arrangement - The present invention is a gaming machine such as a slot machine having a housing with a light-effect arrangement for creation of light effects. The gaming machine has at least one reflector arranged on the housing such that the reflector is positioned with respect to a remote light source to reflect a light beam from the remote light source at least partly towards the front of the housing. The housing may include a light source, which may be a strip of LED lights that emits a light beam. This arrangement is particularly beneficial in modern gaming devices. A higher degree of design freedom relative to light source arrangement is achieved through the use of reflectors and the light source. | 05-19-2011 |
20120190429 | GAMING SYSTEM AND METHOD OF USE - A gaming system and method involving a fixed bonus code and dynamic game code wherein one or more players playing multiple designated electronic gaming machines attempt to match a dynamic game code to the bonus code to win a fixed jackpot or progressive jackpot. The game code symbols adjust randomly (i.e., change) responsive to each play of a corresponding electronic gaming machine. Once a game code symbol matches a corresponding bonus code symbol, the game code symbol locks up such that the matching game code symbol cannot adjust again until the jackpot is won based on each game code symbol matching a corresponding bonus code symbol. Different electronic gaming machines may be re-assigned to drive different game code symbols as needed. | 07-26-2012 |
20130175756 | DEVICE FOR INSERTING BANK NOTES INTO A BANK NOTE PROCESSING DEVICE - A device for inserting bank notes into a bank note processing device. The bank note processing device has a main body, a support surface for supporting a bank note to be inserted on a flat side, and at least one lateral positioning edge for laterally positioning the slot on the bank note processing device and/or for connecting the slot to the bank processing device in an accurately fitting manner. The device for inserting bank notes into a bank note processing device is characterized by a setting mechanism for variably setting the position of the positioning edge transversely to the insertion direction of the bank note through the slot. | 07-11-2013 |
20150027848 | DEVICE FOR INSERTING BANK NOTES INTO A BILL ACCEPTOR - A device for inserting bank notes into a bank note processing device. The bank note processing device has a main body, a support surface for supporting a bank note to be inserted on a flat side, and at least one lateral positioning edge for laterally positioning the slot on the bank note processing device and/or for connecting the slot to the bank processing device in an accurately fitting manner. The device for inserting bank notes into a bank note processing device is characterized by a setting mechanism for variably setting the position of the positioning edge transversely to the insertion direction of the bank note through the slot. | 01-29-2015 |

20080205780 | LOSSLESS EMBEDDING OF DATA IN DIGITAL OBJECTS - Current methods of embedding hidden data in an image inevitably distort the original image by noise. This distortion cannot generally be removed completely because of quantization, bit-replacement, or truncation at the grayscales 0 and 255. The distortion, though often small, may make the original image unacceptable for medical applications, or for military and law enforcement applications where an image must be inspected under unusual viewing conditions (e.g., after filtering or extreme zoom). The present invention provides high-capacity embedding of data that is lossless (or distortion-free) because, after embedded information is extracted from a cover image, we revert to an exact copy of the original image before the embedding took place. This new technique is a powerful tool for a variety of tasks, including lossless robust watermarking, lossless authentication with fragile watermarks, and steganalysis. The technique is applicable to raw, uncompressed formats (e.g., BMP, PCX, PGM, RAS, etc.), lossy image formats (JPEG, JPEG2000, wavelet), and palette formats (GIF, PNG). | 08-28-2008 |
20090154809 | Method and apparatus for identifying an imaging device - A new technique for identifying whether images are derived from a common imager, e.g., a camera, or other imaging device such as a scanner, based on the device's measured or inferred reference noise pattern, a unique stochastic characteristic of all common digital imaging sensors, including CCD, CMOS (Foveon™ X3), and JFET. The measured or inferred noise pattern of two images may be extracted and then cross correlated, with a high correlation being consistent with a common imager. Various preprocessing techniques may be used to improve tolerance to various types of image transform. It is also possible to perform the analysis without explicit separation of inferred image and inferred noise. | 06-18-2009 |
20090257671 | Method and apparatus for identifying an imaging device - A new technique for identifying from images a camera, or other imaging device such as a scanner, is based on the device's reference noise pattern, a unique stochastic characteristic of all common digital imaging sensors, including CCD, CMOS (Foveon™ X3), and JFET. First, one determines from images the sensor's reference pattern noise, which uniquely identifies each sensor. To identify the sensor from a given image, the presence or absence of the reference pattern noise in the image under examination is established using a correlation detector or other means. | 10-15-2009 |
20120230536 | DETERMINING WHETHER OR NOT A DIGITAL IMAGE HAS BEEN TAMPERED WITH - Apparatus and method to verify the integrity of a digital image (i.e., deciding whether or not the entire image or just a portion has been tampered with, and/or finding the doctored area in the image). One first determines the imaging sensor's reference pattern noise, which serves as a unique fingerprint that identifies the imaging sensor that captured the image. To verify the integrity of the content in a region of the image, a correlation detector determines the presence or absence of the imaging sensor's reference pattern noise in that region, thereby verifying whether or not the image has integrity. The correlation detector can also find automatically one or more regions in the image that were tampered with. | 09-13-2012 |
