Abstract: A storage phosphor reader. The reader comprises a first roller pair, a cylindrical scan platen, a guide member, and a holding member. The first roller pair transport a storage phosphor medium along a path in a first direction. The cylindrical scan platen supports the medium as it is scanned by a scanner. The guide member is disposed intermediate the first roller pair and the scan platen for guiding the medium to the scan platen. The holding member is disposed downstream of the scan platen for contacting the medium after it is scanned.

Abstract: An apparatus for the recovery of a halogen or pseudohalogens from a halide compound in solution; wherein the apparatus includes an electrochemical cell including, an electrode assembly including at least a first and second electrodes in communication with a controller for providing a current to at least two of the electrodes; wherein, upon delivery of a predetermined voltage, the halide compound is oxidised at one or more of the electrodes to form a halogen corresponding to the halide in solution whereupon the halogen is deposited on said one or more electrode upon completion of oxidation.

Abstract: Conventionally, multiple session discs are provided with backward going pointers (P). It is now disclosed that it is possible to navigate a multiple session disc without the provision of such pointers (P). A multiple session optical disc which also acts to copy protect audio data has a first audio session (40) and a second data session (60). The data session (60) has a Lead-In (LI), a program area (32), and a Lead-Out (LO). It also has a primary volume descriptor (50) containing control data identifying the files within the data session but there is no pointer from the Lead-Out (LO) of the session (60) to any part of the program area (32). The audio session (40) has a program area (32) extending between the Lead-in (LI) and the Lead-Out (LO). To copy protect the audio information, the audio data (40) is hidden from a data reader. For example, the Lead-In (LI) to the audio session (40) and the Lead-In (LI) to the data session (60) may each erroneously identify the data in the audio session as data.

Abstract: A radiation detector having glass emitting photons by scintillation in response to incident neutrons and/or electromagnetic radiation of at least about 1 keV, and a system associated with the glass for detecting the presence of photons emitted by scintillation. The glass ceramic material is a fluoride glass matrix having nanocrystalline particles distributed therein substantially all of which are in a phase that scintillates with average diameters of less than about 100 nm in a fluorozirconate matrix. Various metals are disclosed for the ceramic particles and methods of manufacture are also disclosed.

Abstract: A method and apparatus for enabling a licensed end user to record digital data as described is particularly useful to the music industry as it enables them to make audio data available over the internet but to retain control of the uses to which that audio data can be put. Thus, upon completing a financial transaction to pay for the required audio tracks, the end user is enabled to download and decrypt encrypted music tracks and to play them on the end user's personal computer. The end user can also be allowed to burn a CD including the downloaded music tracks. However, the end user is only enabled to decrypt and record the music tracks onto the CD if the music tracks are recorded together with copy protection.

Abstract: A method for copy protecting a record carrier is disclosed, in which method the copy protected record carriers are provided with a pattern of logical errors which cannot be corrected by the error correcting rules predefined for said record carrier. The pattern of logical errors represents access control information. The logical errors are generated during decoding the bit sequence read from the record carrier. Bit errors may be positioned in the bit sequence so as to counteract de-interleaving which is part of an error decoding process in a reading device and accumulate in error words which are uncorrectable. Also a method for detecting access control information and a retrieval arrangement are disclosed, which retrieval arrangement serves to detect the access control information by selecting at least one error location, but not all error locations on the record carrier, and verifying the presence of an error by reading the selected error location via the reading means.

Abstract: A distributed virtual multiprocessor having a plurality of nodes coupled to one another by a network. A first node of the distributed virtual multiprocessor page faults in response to an instruction that indicates a memory reference at a virtual address. The first node indexes a first address translation data structure maintained therein to obtain an intermediate address that corresponds to the virtual address, then transmits the intermediate address to a second node of the distributed virtual multiprocessor to request a copy of a memory page that corresponds to the intermediate address. The first node receives a copy of the memory page that corresponds to the intermediate address from the second node, stores the copy of the memory page at a physical address, then loads a second address translation data structure with translation information that indicates a translation of the virtual address to the physical address.

Abstract: A method and system allows a service provider to provide Intranet services remotely by assigning private virtual servers to customers. Each customer addresses transmissions to one or more private virtual servers using private addresses from the customer's private Intranet. The addresses of different private virtual servers do not have to be unique and may overlap. Customers exchange privately-addressed transmissions with the service provider using tunnels to traverse the local or regional network connecting the customer with the service provider. The service provider routes the transmissions to the relevant private virtual server belonging to the customer that sent the transmission. The service provider also routes privately-addressed transmissions back to individual customers using tunnels.

Abstract: It is proposed to copy protect data files for transmission by incorporating DSV data patterns, that is, data patterns which are difficult to encode without causing DSV problems, in the data files. The data in five audio streams and two video streams is placed, by way of encoders (10) and a multiplexer (12) into a stream of blocks of encoded data in the MPEG file format (14). In this format, blocks of video data V are arranged alternately with blocks of audio data A and padding stream blocks P. DSV data patterns (16) are incorporated into the MPEG file (14) by way of an encoder (18) to produce the copy protected data file (15). The DSV data patterns (16) are incorporated into locations within the MPEG file which have no data content such as padding stream blocks P and/or into unused audio data blocks A.

Abstract: According to this invention, a conventional pair of golf gloves is provided with pads across the palm portions thereof which abut the grip portion of a golf club shaft to automatically align the shaft for proper gripping. The guide pads are so positioned across the palm portions of the gloves that when the golf club head is sole on the ground and the upper and lower gripping hands of a golfer wearing the gloves receive the grip portion of the club shaft across the palms of the glove and against the pads, the shaft will lie diagonally across the roots of the fingers and when the hands are closed around the shaft with the guide pads cradling the grip portion of the golf club distal from the golf club head, an automatic proper gripping of the golf club will be insured. The guide pads are substantially parallel to the transverse creases of the hand, lying diagonally across the roots of the fingers. The pad on the first glove spans substantially the entire palm of the hand.

Abstract: A method and apparatus for dynamically shifting between switching and routing packets efficiently to provide high packet throughput. The present invention provides a method for transmitting packets between an upstream node and a downstream node in a network that utilizes flow classification and labelling to redirect flows. The method includes the steps of establishing default virtual channels between the upstream node and the downstream node, receiving a packet at the downstream node, performing a flow classification at the downstream node on the packet to determine whether the packet belongs to a specified flow that should be redirected in the upstream node, selecting a free label at the downstream node, and informing the upstream node that future packets belonging to the specified flow should be sent with the selected free label attached.
