  • Publication number: 20200266977
    Abstract: Multiple bit values can be encoded on a single photon in a quantum key distribution (QKD) system using a plurality of sidebands of an optical carrier frequency. Computational and conjugate bases can be defined, and photons decoded based on a selected state from either basis. If n sidebands are available, as many as log2n bits can be encoded on a single photon. Errors in detected bit values due to selection of an incorrect basis state or other errors can be at least partially corrected by bit distillation to identity bit strings for which a transmitter and a receiver record the same values, without insecure transmission of these values.

  • Publication number: 20200252215
    Abstract: Message authenticators for quantum-secured communications facilitate low-latency authentication with assurances of security. Low-latency message authenticators are especially valuable in infrastructure systems where security and latency constraints are difficult to satisfy with conventional non-quantum cryptography. For example, a message transmitter receives a message and derives an authentication tag for the message based at least in part on an authenticator that uses one or more quantum keys. The message transmitter outputs the message and its authentication tag. A message receiver receives a message and authentication tag for the message. The message receiver derives a comparison tag for the message based at least in part on an authenticator that uses one or more quantum keys. The message receiver checks whether the message is authentic based on a comparison of the authentication tag and the comparison tag. In example implementations, the authenticator uses stream-wise cyclic redundancy code operations.

  • Patent number: 5474672
    Abstract: The instant device serves to remove petroleum substances from pumped bilgewater in small boats. Bilgewater under pressure is pumped into a media housing chamber after having first passed into a filter housing chamber containing polyethylene beads that separate the petroleum substances from water. The purified water under pressure is pumped out of the media housing chamber. When petroleum product that is so separated builds up in concentration to a certain critical level, an electrical sensing component is activated serving to notify a person to open a petroleum product outline control valve on the media housing chamber and to close an outflow control valve on outflow piping attached to he media housing chamber in order to permit such petroleum substances to be pumped away into a collecting pan.

  • Patent number: 5191731
    Abstract: A lure body is disclosed as having a slot in communication with a central opening in the lure body to permit attachment of the lure body to a leader or fish line by lateral passage into and through the slot into the opening. The slot width is restricted to prevent all but intentional manipulation of the leader or fish line through the slot in order that the lure body says on the leader or fish line during fishing. The wall surfaces are chamferred to facilitate line entry into the slot.

  • Patent number: 4989361
    Abstract: A length of wire or like material serves to insertably receive the bait selected. One end of the bait holder is shaped for snap on engagement with an elongate main member of a fishing lure while the remaining end of the holder is retained in place by removable engagement with a sleeve. The bait laden holders can be readily attached and removed from the lure.

  • Patent number: 4154575
    Abstract: An apparatus which provides for a constant center distance between all drive components in a hot roll fusing assembly during fusing nip opening/closing. This apparatus includes a roll closure device which utilizes a high mechanical advantage toggle mechanism in conjunction with a cam drive. The toggle mechanism is comprised of a pivot arm pinned to the fuser frame and a force-cell attached to the pivot arm and the shaft through the backup roll. The backup roll is constrained to rotate about the cam shaft. When the cam rotates, it rotates the pivot arm, which in turn drives the backup roll either towards or away from the hot roll while maintaining a constant center distance between the backup roll center line and a center line through the cam shaft. The drive means for the backup roll includes a first gear drivingly coupled thereto which rotates on the same axis and which meshes with a second gear rotating on the same shaft as the cam.

  • Patent number: 4145181
    Abstract: Apparatus in a copier fusing assembly for distributing the wear on a hot roll occasioned by the use of variable length copy sheets. This wear is distributed over the horizontal length of the hot roll by reversing the hot roll, end-for-end. Easy reversal of the hot roll is made possible by utilization of a hot roll subframe which is removably mounted in the copier fuser mainframe. A hot roll handle on the subframe allows for manual removal of the subframe and hot roll from the mainframe and out of the copier where they are reversed and inserted back into the mainframe. Operation of a latch handle moves a sheet detach bar and sheet transport exit-ways away from the downstream side of the fusing nip to facilitate jam clearance.

  • Patent number: 4110068
    Abstract: An electrophotographic copier having a hot roll fuser assembly. This assembly is slidably supported by a pair of rails. When the fuser assembly is locked into its fusing position, within the copier, it is relatively inaccessible for purposes of inspection, cleaning and/or jam clearance. In its withdrawn, inoperative position, a single manually operable jam clearance handle is operator accessible. Manual actuation of this handle, from a folded to an extended position, is effective to move both a sheet peeler or detach bar, and a sheet transport channel away from the fusing nip. When the handle is moved back to its folded position, the sheet detach bar and transport channel are accurately positioned, and locked in an operative position closely adjacent to the downstream side of the fusing nip, so as to aid in release of the sheet from the fusing nip, and to guide the sheet away from this nip.
