Title: Automatic fault recovery in a packet network
Inventor: FITE FRANKLIN D JR
IPC: H04L12/56
Filed: 1990-11-02
Granted: 1996-11-19
Abstract: A transmission is disclosed for recovering from faults in transmission equipment or facilities forming so-called virtual circuits for transmitting packets in a network. Faults are detected in transmission paths associated with a network node and an individual fault indication message is generated for each network facility that has at least one virtual circuit affected by the fault. Each fault indication message includes the identity of each virtual circuit on the associated network facility affected by the fault. The message is transmitted in-band on at least one of the affected virtual circuits on the associated network facility. If affected virtual circuits are terminated in the node, they are switched to alternate virtual circuits. Otherwise, the fault indication messages are transmitted over the identified facilities to other unknown nodes. A node receiving a fault indication message determines which virtual circuits identified in the message are terminated in the node and which virtual circuits pass through the node. The virtual circuits that are terminated in the node are switched to alternate virtual circuits. For virtual circuits passing through the node, the network facilities associated with them are identified and a new fault indication message is generated for each of the identified facilities. Each of the generated fault indication messages is transmitted in-band on at least one virtual circuit on the, respective, identified network facility. (FIG. 2)

Title: Distributed multilevel computer security system and method
Inventor: BARLOW DOUGLAS C
IPC: G06F21/20
Filed: 1991-06-07
Granted: 1995-12-26
Abstract: A  computer  network  has  a  number  of  computers  coupled thereto at distinct nodes.   A trust realm table defines which computers are members of predefined trust realms. All the members of each predefined trust realm enforce a common  set  of  security  protocols  for  protecting  the confidentiality of data.  Each computer that is a member of a trust realm enforces a predefined security policy, and also defines a security level for each set of data stored in the computer.   Thus,  each message has an associated label  denoting  how to  enforce  the  computer's  security policy with respect to the message.  A trust realm service program prepares a specified message for transmission to a specified other computer system.   To do this it uses the trust realm table to verify that both the computer system and the specified computer system are members of at least one common trust realm,  and then selects one of those common trust realms.   The message  is transmitted as a protocol data unit, which includes a sealed version of the message, authenticated identifiers for the sending system and user, the message's label, and an identifier for the selected trust realm.   Received protocol data units are processed by validating each  of the  components  of the received protocol data unit before accepting the sealed message in the protocol data unit as authentic.  Further, the label in the received protocol data unit is used by the receiving computer to determine what predefined security policy is to be enforced with respect to the message.

Title: Signal processing system of optical fiber gyro
Inventor: WASHIMI KOUICHI
IPC: G01C19/72
Filed: 1991-08-14
Granted: 1996-02-27
Abstract: A signal processing system of an optical fiber gyro comprises a light emitting element for generating a monochromatic light, a fiber coil, a branching element for dividing the monochromatic light into clockwise and counterclockwise lights, for transmitting the clockwise and counterclockwise lights to opposite ends of the fiber coil, respectively, and for uniting again the clockwise and counterclockwise lights into a coherent light, a light receiving element for detecting an intensity of the coherent light, and an auxiliary light receiving element for monitoring an output of the light emitting element.  When the light emitting element output is less than a predetermined value, a power for driving the light emitting element is controlled so that a direct current component or even times higher harmonics component of a sensor signal obtained from the light receiving element becomes constant.  When, on the other hand, the light emitting element output has reached the predetermined value, the light emitting element output is controlled by a monitoring signal of the auxiliary light receiving element so that it does not exceed the predetermined value.

Title: Countertop can crusher
Inventor: BENSON JOHN D
IPC: B30B9/30
Filed: 1991-11-15
Granted: 2003-09-23
Abstract: An apparatus for crushing workpieces includes a drive mechanism having a gear reduction train and a moveable rack member which is centered above a compression plate for even, linear force transmission. Force is transmitted to the rack member on two opposite sides thereof by a pair of pinions which engage apposite rows of rack teeth. The compression plate is integral with a pair of opposite guide sleeves, which are mounted for sliding movement with respect to vertically extending guideposts.      A'crimper mechanism is mounted to the compression plate for crimping the workpiece prior to compression. The combination of the improved drive train, which prevents jamming of the apparatus due to uneven force transmission, and the crimper mechanism allows a relatively small motor to be used in the unit, which increases its portability, economy and affordability. An additional aspect of the invention involves an overload sensor arrangement, which causes the apparatus to reverse in mid-stroke if too much compressive force is being generated between the compression plate and the workpiece. A door interlock switch arrangement makes the apparatus safer for use by children or other persons.
