Title: Data hiding method and data extracting method
Inventor: TEZUKA SHU
IPC: G06F21/62
Filed: 1997-11-12
Abstract: To hide message information into media information in frequency space. With this, it is the objective of the present invention to provide a data hiding method which has high resistance to removal or change of message information embedded into media information and which continues to effectively maintain hidden message information even when signal processing is performed by employing a frequency filter. In order to hide message information (m) into media information (M), the frequency transform of the message information (m) and the media information (M) are performed, and frequency spectra f1 and f2 are obtained. Next, from the frequency spectrum f2 of the message information (m), a region containing feature frequency components representative of the features of the message information (m) in real space is extracted as the base region B. Then, n copies of the base region B are generated, and in frequency space, the n copies are dispersedly arranged. Also, by making the frequency components other than that equal to zero, a frequency spectrum f3 is generated as intermediate information. Finally, the frequency spectrum f3 and the frequency spectrum f, are added, and by performing the inverse frequency transform of the result, the message information (m) can be hidden into the media information (M).

Title: Optical data storage
Inventor: NORDAL PER-ERIK
IPC: G11B7/24085
Filed: 1996-05-22
Abstract: A data carrying medium comprises a fluorescent layer with data carrying structures. The fluorescent layer includes fluorescent dye molecules embedded in a polymer base material. By employing a laser beam in order to create the data carrying structures, these obtain a lower fluorescence in relation to the fluorescence from a corresponding region of the virgin, fluorescent layer when the data carrying structure is irradiated with fluorescence exciting radiation. By modulating the laser beam several bits can be stored in each data carrying structure, with the result that the value of a stored datum corresponds to the value of a specific level in a multilevel code. The stored data are read by means of fluorecence excitation of the fluorescent dye molecules in the data carrying structure. The fluorescence is detected in a detector device, the intensity of the detected fluorescence corresponding to the value of the stored datum. In this fashion 1-10 bits can be stored in a data carrying structure smaller than 0.25 µm2. This is a substantial increase in the data density compared to previously known optical data storage media.

Title: Integration of link generation, cross-author user navigation, and reuse identification in authoring process
Inventor: SOBIESIAK RICHARD
IPC: G06F17/30
Filed: 1998-02-13
Abstract: A process for professional authoring of information about structured domains by which authors, as an integral part of the authoring  process,  provide  the  data  needed  to  (1)  enable intelligent user navigation between the work of different authors without the need for predefined links;  (2) enable searches for information  based  on  user  context;  and  (3)  identify  reuse candidates before information is written and, therefore, minimize duplication. Authors develop concept maps to reflect the structure of the domain rather than the structure of the documentation; define the user context to which a concept map applies; resolve topic intersections between concept maps; define query attributes for articles to be developed; and resolve article intersections identified by means of intersecting query attributes. Computer programs support concept map development, the identification and analysis of topic and article intersections, and association of the data for exploitation in a user interface.

Title: Dispositif d'administration de medicaments
Inventor: GROSS JOSEPH
IPC: A61M37/00
Filed: 1996-08-30
Abstract: La présente invention concerne un dispositif (10) d'administration de médicaments constitué d'un réservoir contenu dans un boîtier (11) et d'un organe permettant de faire sortir le médicament du réservoir. Le dispositif est équipé d'un mécanisme de remplissage sur lequel est monté un récipient (19) à médicament fermé de façon étanche par un bouchon (25) pénétrable. Le mécanisme comporte un alésage interne (20) accueillant une tige interne (21) de laquelle dépasse une aiguille (22). Cette aiguille (22) est creuse et en communication avec le réservoir. Pour remplir le réservoir, le procédé consiste à enfoncer le récipient (19) dans l'alésage (20), ce qui provoque la percée du bouchon (25) par l'aiguille (22), la poussée du bouchon contre la tige (21) entraînant un effet de piston poussant le médicament hors du récipient (19) au fur et à mesure de l'enfoncement du récipient (19) dans l'alésage (20) et de son déplacement par rapport au bouchon (25). Il est ainsi possible de remplir le réservoir d'un médicament stérile qui reste stable une fois stocké dans le récipient (19), le remplissage s'effectuant simplement sans utilisation de seringue. Un autre avantage provient de l'aiguille d'administration montée sur le pourtour de la surface inférieure du boîtier. En effet, cette configuration permet de disposer l'organe d'entraînement contre la peau, ce qui garantit une plus grande stabilité thermique et un fonctionnement plus facilement prévisible du dispositif.

Title: Method for reducing the offset voltage of a hall device
Inventor: MAIER CHRISTOPH
IPC: H01L43/06
Filed: 1997-09-09
Abstract: The method serves for dynamically compensating the offset voltage of a Hall device. The Hall device can have either a platelike structure with at least two contact pairs (AC, BD), or any other arrangement deriveable by conformal mapping. The contact pairs (AC, BD) are angled by e.g. 90°. Each pair is supplied with a periodically alternating current whereby the phase shift of the supply currents corresponds to the spatial phase shift of the contact pairs and is e.g. 90°. Superposition of the supplied currents results in a continuously spinning current vector in the Hall device. By measuring simultaneously the voltages (V AC, V BD) between corresponding terminals, a signal (V HO) consisting of the Hall voltage and a periodic offset voltage can be isolated.     The offset voltage (V O) is eliminated by averaging the signal over at least one period.

Title: Method and apparatus for playing a poker-like game
Inventor: NUCIFORA PATRICK M
IPC: A63F3/00
Filed: 1998-07-09
Abstract: When played as a casino table game, the poker-type game of the present invention consists of a dealer and from one to six players and is playedwith a standard 52 card deck. After each player places an ante wager, the dealer deals three cards face down to each player. Each player then either foldsand loses his bet or stays by placing a second wagering bet. A fourth face down card is then dealt to each player who either folds or places an additional raisebet. A fifth face-up card is then dealt to each remaining player. Losing hands are locked-up and winning hands are paid by the dealer according to the odds listed in a payout table. The object of the game is for a player to form a five card poker hand that has the highest possible poker hand ranking. The electronic version of the game is played in essentially the same manner except that only one hand is dealt. After the player inserts a coin or otherwise places his ante wager, three cards are dealt face up. The player then decides whether to fold or place a second wager for a fourth card. Again, the player decides whether to fold or place a double raise wager for his fifth card. If, after receiving the fifth card, the player has a winning hand, he is paid based on a payout table or he is determined to be a loser and all wages are forfeited.
