Abstract: The mobil base station is disclosed having a computer readable storage medium for information and mobil wireless communication circuitry for performing wireless communication with a user in its broadcast area. In a complimentary configuration, the user has a terminal with a computer readable storage medium for storing information and terminal wireless communication circuitry for cooperating with the mobil wireless communication circuitry to facilitate wireless communication therebetween. The mobil base station performs a wireless transfer of information by moving to the user'sparticular geographical area such that its broadcast area includes the user's terminal. Using the mobil wireless communication circuitry and the terminal wireless communication circuitry, a wireless communication link is established. A transfer of information then occurs between the storage medium of the mobile base station and the storage medium of the terminal via the wireless communication link.

Abstract: Apparatus for forming a cased glass stream that includes at least one pair of aligned orifices coupled to sources of core and casing glass such that glass flows by gravity from the first and second sources through the aligned orifices to form a cased glass stream. The orifices are carried by an orifice housing mounted on a frame for movement into abutment seating engagement of the orifice housing against the core and casing glass delivery mechanisms. The frame in accordance with the present invention includes a gimbal mounting arrangement mounting the orifice housing to the frame so as to be pivotable about a pair of pivot axes that are orthogonal to each other and to the axis of alignment of the orifices. This gimbal mounting arrangement helps accommodate misalignment between the seating surfaces on the orifice housing and the glass delivery mechanisms, and to reduce glass leakage during operation.

Abstract: An easy-open beverage container and opening system therefor includes first and second barrier walls having top edges and upper portions of opposite side edges which matingly face one another and which form an open top therebetween. A bifold membrane with a longitudinal fold is located in the open top. A membrane attachment securely attaches peripheral edges of the bifold membrane to adjacent top edges and upper portions of the opposite side edges such that the bifold membrane closes the open top and the facing top edges of the barrier walls are movable away from one another to expose the longitudinal fold for piercing by a straw. In a preferred embodiment, a side attachment securely attaches facing portions of the peripheral edges of the bifold membrane adjacent the upper portions of the opposite side edges so that the facing upper portions of the opposite side edges are not movable away from one another and thus the facing top edges tend to stay together and protect the bifold membrane. In another preferred embodiment, the opening system further includes a peel seal provided between facing portions of the peripheral edges of the bifold membrane adjacent the top edges of the barrier walls.      The peel seal provides a tamper-evident and sanitary seal for the bifold membrane which is easily broken. For easier opening of the peel seal, a respective pull tab or extension is present adjacent to respective peripheral edges of the bifold membrane adjacent the top edges of the barrier walls.

Abstract: The invention provides a method and system for performing XOR operations without consuming substantial computing resources. A specialized processor is coupled to the same bus as a set of disk drives; the specialized processor reviews data transfers to and from the disk drives and performs XOR operations on data transferred to and from the disk drives without requiring separate transfers. The specialized processor maintains an XOR accumulator which is used for XOR operations, which records the result of XOR operations, and which is read out upon command of the processor. The XOR accumulator includes one set of accumulator registers for each RAID stripe, for a selected set of RAID stripes. A memory (such as a contents-addressable memory) associates one set of accumulator registers with each selected RAID stripe.

Abstract: A watermarking system allowing both sufficiently high quality of watermarked moving pictures and enhanced ease of watermark detection is disclosed. A watermark level of a watermark to be embedded into a picture of data is changed depending on the picture type of a selected block of frequency component data, and then a watermark having the watermark level is inserted into the selected block of frequency component data.      Therefore, a moving-picture can be effectively embedded with a digital watermark without substantially reducing the quality of image and the digital watermark can be detected reliably.
