Abstract: In a reconfigurable communications system, circuit status bits are stored in a first matrix of rows associated respectively with predefined network configurations and columns associated respectively with predefined circuit configurations. Destination status codes are stored in a second matrix of rows associated respectively with the circuit configurations and columns associated respectively with switching nodes of the system. Each circuit configuration comprises one or more transmission links and each circuit status bit stored in each column of the first matrix pattern indicates the presence or absence of the circuit configuration associated with that column. Each destination status code indicates the presence or absence of transmission links from each switching node to possible destination nodes. In response to a manual command, the circuit status bits stored in one of the rows of the first matrix are respectively multiplied with the destination status codes stored in each column of the second matrix, and the multiplied binary values are summed so that network configuration data is derived with respect to a desired network configuration, which is then transmitted to the switching nodes to reconfigure the system.

Abstract: A method and apparatus for implementing a thermodynamic cycle. A heated gaseous working stream including a low boiling point component and a higher boiling point component is expanded to transform the energy of the stream into useable form and to provide an expanded working stream.  The expanded working stream is then split into two streams, one of which is expanded further to obtain further energy, resulting in a spent stream, the other of which is extracted.  The spent stream is fed into a distillation/condensation subsystem, which converts the spent stream into a lean stream that is lean with respect to the low boiling point and a rich stream that is enriched with respect to the low boiling point component. The lean stream and the rich stream are then combined in a regenerating subsystem with the portion of the expanded stream that was extracted to provide the working stream, which is then efficiently heated in a heater to provide the heated gaseous working stream that is expanded.

Title: Envelope dispenser door mechanism for automated teller machine
Inventor: RAMACHANDRAN NATARAJAN
IPC: G07D11/00
Filed: 1995-09-15
Granted: 1999-01-12
Abstract: An envelope dispenser (50) for use in an automated teller machine includes a lockable access door (14). The door includes a slot (20), integral with its first face (16). The door is locked by the engagement of a first member (36) in a first notch portion (24) of the slot. The door is unlocked by an actuator (46) which upon the receipt of an electrical signal moves the first member into a central portion (28) of the slot. In this position the door may be manually moved to a fully open position by a user. In the open position the actuator urges the first member into a second notch portion (26), which releasably holds the door in the open position. In the open position envelopes stored in the machine may be accessed. From the open position the door can either be manually closed or automatically closed by the cessation of the electrical signal which enables a spring (44) to move the first member to the central portion of the slot. Once the door is returned in the closed position and the actuator de-energized, the first member returns to the first notch portion again locking the door.

Abstract: An active-fixation medical electrical lead having an improved turning tool. In particular, the lead has a fixation helix attached to a coiled conductor, the coiled conductor is attached at the opposite end ~o a connector assembly. The coiled conductor is covered by an insulative sheath between the fixation helix and the connector assembly. Mating with the connector assembly is the improved turning tool. The turning tool features essentially three components: housing, roller assembly and header.      Housing is shaped so as to frictionally couple with a sealing ring of the connector assembly while permitting a connector pin of the connector assembly to extend therethrough and into roller assembly.     Through such a combination the roller assembly may be rotated relative to housing thereby causing connector pin to rotate relative to sealing ring and thus extend or retract a fixation helix. Header further permits a stylet to be guided through turning tool and remain within lead while in use. Ultimately such a device permits a physician to extend as well as retract a helix with only one hand.

Title: Additional heating system
Inventor: HUMBURG MICHAEL
IPC: F01P3/20
Filed: 1995-09-29
Granted: 2004-09-14
Abstract: The invention relates to the arrangement of an additional heater for the coolant circuit of an internal combustion engine of a motor vehicle, which coolant circuit comprises, on the one hand, a cooling circuit including the coolant/air radiator and, on the other hand, a heating circuit including the coolant/air heat exchanger for heating the passenger compartment. The technical problem with coolant circuits of modern engines, in particular diesel engines, consists, inter alia, in the fact that too little heat is available for the heating - consequently so-called additional heaters are used, e.g. fuel heaters. It is proposed to arrange the additional heater, which is configured as a fuel heater with a burner part and a heat exchanger part, directly on the coolant/air radiator of the vehicle or to integrate it into the radiator. This arrangement has the advantage that the burner with its fuel and exhaust gas lines is located outside the passenger compartment of the motor vehicle and thus does not adversely affect comfort and safety in the passenger compartment. Additionally, the flow-related inclusion of the additional heater in the coolant circuit is simpler and more cost-effective.

Abstract: A system (10) for reading package information includes an imaging system (12) and a label decoding system (14). The imaging system (12) captures an image of a package surface (34) that includes a machine readable code such as a bar code (36) and an alphanumeric destination address (38). The label decoding system (14) locates and decodes the machine readable code and uses  OCR techniques to read the destination address (38). The destination address is validated by comparing the decoded address to a database of valid addresses. If the decoded address is invalid, an image of the destination address is displayed on a workstation (30) and an operator enters the correct address. The system (10) forms a unified package record by combining the decoded bar code data and the correct destination address data. The unified package record is used for subsequently sorting and tracking the package (20) and is stored in a database and applied to a label that is affixed to the package (20).
