Title: Tire shredding machine and method of using the same
Inventor: CRAMER NEAL R
IPC: B02C18/22
Filed: 2000-05-16
Granted: 2005-02-22
Abstract: A tire shredding machine which does not require the massive amount of machinery required for existing tire shredders and which is safe and simple to use is disclosed. The tire shredding machine (10) of the present invention essentially includes a housing (12) with a safety hood (30), several wheels (14, 16a, 16b, 18a, 18b, 20a, 20b, 34, 38) and guide elements or wings (22a, 22b). In order to shred a tire (42), the tire (42) is cut in half and each half is fed into the machine (10) one at a time. The safety hood (30) remains in an open position until the tire (42) is fed into the machine (10). Once the tire (42) is in the machine (10), the hood (30) is placed into a closed position, a switch is activated, and the wheels (14, 34) pull the half of the tire (42) into the machine (10). The tire (42) contacts the guide elements (22a, 22b) which, in turn, spread out or flatten the tire (42) so that the tire (42) may be fed into a grinder (38) which shreds the tire (42).

Abstract: A communications manager provides communication services for an activity-based collaboration system, in which data change requests comprising deltas are communicated over a network between network-capable devices. The communications manager is operable on a local network capable device for sending locally-generated deltas over the network to at least one remote network-capable device and for receiving remotely-generated deltas over the network from the at least one remote network-capable device. The communications manager can send the deltas via unicasting, muticasting, or broadcasting techniques. The communications manager is responsive to network connection status information indicating that the remote network-capable device is connected to the network for sending the local deltas directly to an address for the remote network-capable device. A presence mechanism maintains and distributes, on request, the network connection status information, which it acquires from each of the network-capable devices. The communications manager is also responsive to the network connection status information indicating that the remote network-capable device is disconnected from the network for sending the local deltas to an address of a relay. The relay stores deltas until the relay is notified that the remote network-capable device has reconnected to the network, and then the relay sends the deltas to the reconnected remote network-capable device.

Inventor: FURUKAWA JUN
IPC: H04L9/28
Filed: 2002-05-07
Granted: 2007-07-17
Abstract: The present invention provides a certified shuffle--decrypting system, which does not require shuffled encrypted texts to be output, and in which the amounts of calculation and certificates are minimized to allow efficient processing, and the certified shuffle-decrypting system generates shuffle-decryption certificates certifying that multiple encrypted texts have been shuffle-decrypted correctly, and verifies, based on the shuffle-decryption certificates, whether or not the shuffle-decryption has taken place correctly. This system comprises: a certified shuffle--decryption device for shuffle-decrypting the multiple encrypted texts to generate the shuffle-decrypted texts, and for generating the shuffle-decryption certificates; and a shuffle-decryption verification device for verifying whether or not the shuffle-decryption has taken place correctly, by referring to the generated shuffle-decrypted texts and the shuffle-decryption certificates for the shuffle-decrypted texts. The certified shuffle-decryption device: decrypts, with the secret keys, the shuffled encrypted texts obtained by shuffling the order of the encrypted texts and encrypting them with public keys, thereby generating the shuffle decrypted texts; generates responses as a reference for the certifications; generates certificates certifying, based on the responses, the validities of the shuffling of order, the encryption and the decryption for obtaining the shuffle decrypted texts; and outputs the generated certificates and the responses as shuffle-decryption certificates.

Abstract: Oligonucleotide building processes are monitored by means of an oligonucleotide probe which in one embodiment is labelled at one end with a chemiluminescent label and at the other end with a quencher molecule. The conformation of the oligonucleotide probe changes according to whether the probe hybridises with a substantially complementary nucleic acid sequence. In the non-hybridised state the chemiluminescent label is sufficiently close proximity to the quencher that the chemiluminescent emission is substantially attenuated, but in the hybridised state the separation is such that there is little or no attenuation. Particular probes and emitter/quencher pairs are disclosed.

Title: Generating scanning spot locations for laser eye surgery
Inventor: YEE KINGMAN
IPC: A61F9/01
Filed: 2001-03-14
Granted: 2011-05-17
Abstract: Scanning spot locations are generated for ablating tissue using a scanning laser beam (104) over a treatment region by fitting a target function representing a desired lens profile of scanning spots in a particular treatment pattern. Symmetry effects are utilized to simplify the process for determining the scanning spot locations. In some embodiments, the basis function is a two-dimensional function representing a two-dimensional section of a three-dimensional treatment profile which has symmetry a with respect to the two-dimensional section extending along the treatment pattern. For example, the treatment pattern is generally straight for myopic and hyperopic cylinders, and is generally circular for myopia and hyperopia. The target function and the basis function may be discrete for implementation in a software algorithm (20), and be fitted using a least square fit. The fit produces ablation depths for discrete scanning spots which are used to calculate the number of pulses at each reference position along the two-dimensional section. The pulses are distributed along the treatment pattern to produce the desired overlapping effect.

Title: Electronic scoring dart board
Inventor: STEWART MARK F
IPC: A63F9/24
Filed: 2003-01-24
Granted: 2010-07-06
Abstract: A target for use with a projectile has a web defining a target face and has a depth. The web also defines one or more segments within the web that open toward the target face. One or more cups are mounted for sliding within the web and substantially fill the target face of one or more segments of the web. Each of the cups has one or more resilient cushions, between each cup and the back board. Each cushion has one or more electroconductive areas. The back board has an array of switch contacts on a pad forming an electrical switch. The projectile impacts a cup at the target face with sufficient force to cause the cup for that insert to slide within the web and have the electroconductive area of the one or more cushion contact the switch contacts on the pad beneath that cup, resulting in closing of the electrical switch defined by the switch contact. The one or more resilient cushions beneath that cup return the cup substantially to its original position.

Abstract: A sleeve (22) enables attachment of an optic fiber (14) to a multi-integrate d optic chip (10) in optical communication therewith, and maintains alignment of the fiber at its end adjacent the chip. The sleeve includes a symmetrically- shaped cavity (26) bounded by termini (30, 32) which are respectively dispos ed to fit onto the chip and to accept the fiber. An adhesive (46) within the cavity symmetrically bonds the fiber to the chip. The adhesive curs symmetrically in the cavity, to eliminate undersired motion of the fiber fro m its preferred alignment position vis-a-vis the chip connection point (12) or to provide a repeatable motion to achieve the optimum alignment position of the fiber with respect to the chip. The sleeve controls, defines and confine s the index matching adhesive and/or fluid between fiber end (44) and connecti on point (12) by defining the areas and volume actually in contact with the adhesive or fluid. Symmetry is preserved over the effects of gravity and wicking which heretofore have prevented a very symmetrical pigtail which is necessary for performance and repeatability. >
