To an error detection circuit in a decoder, data is supplied which contains an ECC parity sent from a player side of a disk into a decode system. Syndromes for P- and Q-corrections are calculated based on the data contained in the ECC parity. It is, therefore, possible to detect an error with high accuracy.

The aircraft applicable ground fault circuit interrupter interrupts a circuit when a current imbalance is sensed. The circuit interrupter includes a power supply, a sensor for sensing a current imbalance at the line side of the circuit, a logic controller, and a power controller. The power supply provides power to the sensor, logic controller, and the power controller. The logic controller receives input from the sensor, and the power controller receives input from the logic controller, and inte...

The present invention relates to the improved aerodynamic design of a pair of blade profiles valid over a wide range of flow regime. The so formed blades, pertain to high pressure, intermediate pressure and first few stages of low pressure cylinders of axial steam turbines.The invented blades cover a wide range of stagger angles; pitch/chord ratios; inlet flow angles and outlet Mach numbers.

A midplane has a first side to which contact ends of a first differential connector are connected and a second side opposite the first side to which contact ends of a second differential connector are connected. The midplane includes a plurality of vias extending from the first side to the second side, with the vias providing first signal launches on the first side and second signal launches on the second side. The first signal launches are provided in a plurality of rows, with each row having f...

A recyclable electric junction box applicable to automotive vehicles, of the type comprising at least one casing housing a series of circuits inside materialized in one or more printed circuit boards with a series of electroconducting tracks on at least one of its sides, and with a series of components assembled on said plates, welded on said tracks and responsible for carrying out at least one power stage and one signal stage.

A monitoring transducer positioning apparatus, for retention to the body of a patient, comprising an inverted generally cup-shaped holder to receive and position the transducer, first structure associated with the holder to retain it to the patient's body, and second structure on the holder to urge the transducer toward the patient's body, relative to the holder.

A remote control system applicable to the driving and steering mechanism of miniature racing cars, or the like, comprising two direct current motors M2 and M3 (FIG. 5) located within the car, one of said motors positively connected to the drive shaft of the car and the other positively connected to its steering mechanism; and a remote control unit (FIGS. 6, 7 and 8) free from mechanical connection to the car, said control unit comprising a steering control wheel 9 having means associated therewi...

A safety locking mechanism for automobiles wherein the key turning with the lock rotor controls the switch of the vehicle circuitry through a rod coaxially carried by the rotor. The latter releases the bolt of actual locking means for a predetermined angular setting of the key which releases a yielding stop and allows thereby a spring to urge the bolt into its locking position. Another spring urges the rotor back into its normal position for which the engine is operative as soon as the starter h...

Multi-stage networks are used for data stream permutations involving merging and demultiplexing--providing arbitrary data unit time-space interchange that can be used to solve a range of problems particularly in the field of digital data communications, particularly in digital data communication involving advanced networks for exchanging data in packets, cells, or other data units.

A data access method uses variable mask data and shift amount to write data into or read data from a data storage zone. The mask data and shift amount are determined according to starting and end data bit addresses in a bit range of the data to be read or written. Therefore, the data access method is applicable to various platforms with various byte endians.
