Title: Method and ticket for game of chance
Inventor: TENENBAUM HARVEY
IPC: B42D15/00
Filed: 1999-09-28
Abstract: A method of operating a computer system to provide a game of chance for players, based on a horse race in which horses are assigned post positions, in which a ticket is provided having two columns, one for horse post positions and the second containing a number of rows, each containing entry locations for all possible finishing positions. The player marks in each row one finishing position for each horse, a different finishing position for each row, thus producing a player data set, before post positions are assigned to the horses. The player data sets are entered in a central computer. Horse post positions are then drawn and a post position data set is entered in the computer. After the race is run, an outcome data set is entered in the computer and is compared with a combination of the player data set and the post position data set to see whether any player data sets correspond to the outcome data set.

Title: Photonic network node
Inventor: GRAVES ALAN F
IPC: H04B10/2507
Filed: 2000-05-30
Abstract: An all optical network node, also known as a photonic node provides a gateway function for multi-vendor and multi-carrier interworking. The basis of this gateway function is the photonic node as 'master' performance monitor and impairment compensator. Performance monitoring in a photonic node supports network wide performance and fault management, and the triggering of network wide protection and restoration options. The photonic node also supports detection and isolation of photonic node specific faults and mis-connects, triggering protection switching to redundant modules where applicable.      Advantageously, the performance monitoring drives photonic node output channel power level compensation, and potentially, dispersion compensation. This compensation facilitates a common, transparent, 'zero-impairment', optical gateway space capable of concatenating multi-vendor line systems, and interconnecting multi-carrier networks. A photonic node also includes interfacing with, and leveraging the legacy and electro-optics world. For example, when a photonic is in close proximity to electro-optics systems, network and node monitoring of optical channels can be at least partly done by electro-optic systems.

Title: N x m optical switch
Inventor: IYER RAJIV
IPC: G02B26/08
Filed: 2000-06-16
Abstract: An optical switch is disclosed having 4-ports. The switch consists of a first GRIN lens having 2 ports (1 and 3) adjacent its outwardly facing end face, on opposite sides of an optical axis of the lens. A second GRIN lens is disposed to receive light from the first GRIN lens and has two ports (2 and 4) adjacent its outer end face, on opposite sides of an optical axis. In a first state, a first port (1) from the first GRIN lens couples light with port (2) of the second GRIN lens, and a second port (3) of the first GRIN lens simultaneously couples light with another port (4) of the second GRIN lens. A  movable optical element, that when disposed in the path between first and second GRIN  lens, provides only a single connection between a port of the first GRIN lens (1) and a port of the second GRIN lens (4) while preventing light from coupling between the other two ports (2 and 3). Hence a 1 1/2 x 2 optical switch is disclosed. Furthermore, the optical switch is disclosed having multiple input and output ports. The switch consists of a first GRIN lens having 2 ports adjacent its outwardly facing end face. A second GRIN  lens is disposed to receive light from the first GRIN lens and has two ports adjacent its outer end face. In a first state, a first port from the first GRIN lens couples light with a first output port of the second GRIN lens. In a second state, a movable optical element in the form of a light transmissive wedge having a reflective surface, is disposed in the path between first and second GRIN lens, providing a connection between a port of the first GRIN lens and a second port of the second GRIN lens. In a third connect state, the reflective surface of the wedge connects a port of the first GRIN lens and an output port in the same first GRIN lens. Hence an N x M optical switch is disclosed.
