Abstract: An electronic position sensor assembly and engine control system (10) in which two sensing elements (13, 14) in a dual sensor (12) provide separate, independent position signals (A, B) related to multi-cylinder engine cycle position by sensing the angular position of a engine-rotated slotted wheel (11). The sensing elements provide identical sensing signals shifted from each other by a predetermined angular amount (d). In response to the simultaneous providing of a pulse by both sensing elements, a first reference signal (at 22) identifying a reference cylinder is provided for controlling electronic distribution of spark timing and/or fuel injection signals to engine cylinders (17-20). In response to a selected one of the sensing elements producing a pulse which has a predetermined longer duration than a preceding produced pulse, a second reference signal (after 50) is produced indicative of top-dead center engine cylinder cycle position for one of the cylinders. In response to detecting a fault in the position signal produced by the one selected sensing element, a switch (27) selects the other of the sensing elements for utilization in producing the second reference signal, and a substitute   reference signal circuit (40) provides a substitute first reference signal. A less expensive and more reliable engine position sensor assembly and engine control system is provided since proper system operation is maintained despite a fault in one of the position signals.

Abstract: A disk drive system provides all required synchronization, positioning, validation, and data functions within each disk sector. All of these functions are provided within two zones, a header section and a data section. The header section includes a preamble, a synchronization character and an address field, as well as servo information for track following. The data section of each sector includes a data preamble, a data synchronization character, a bad sector bit map, the data and data redundancy information. The header section of at least one sector in a track includes a short DC-erase field, a transitionless segment which is used in synchronization. To synchronize a read/write head to the disk, the system first detects the DC-erase field. The system next searches for the header preamble and synchronization character. If it finds them within predetermined times, it then looks for a valid sector address to complete the synchronization. If the system does not detect the preamble and synchronization character within the predetermined times, it looks for another DC-erase field and continues the synchronization process. After the preamble and synchronization character are found, the desired sector is located by reading the addresses of the succeeding sectors.

Abstract: Method and apparatus for the production of metal granules from a molten metal are disclosed. A molten metal stream (19) is directed against an impact element (8) located above the surface of water in a water tank. The impact of the molten metal upon the impact element causes the molten metal to disintegrate into drops (20) which spread out radially from the impact element. The drops fall down into the water below the impact element in an annular region a certain radial distance from the impact element. The radial distance is varied by varying the velocity of the molten metal stream relative to the impact element at the instant of impact, and/or by varying the height of the impact element above the water surface, in order to substantially continuously vary the radius of the annular region in which the molten metal drops hit the water surface. 
     By using the method and apparatus of the present invention it is possible to granulate metals and metal alloys having a low sinking rate in water and a high enthalpy.

Abstract: A time interval data processing circuit uses a pipelined hardware data processor to perform the conversion of incoming time stamp data into time interval results. These results can be further processed into a hardware accumulated histogram or can be compared against limits to determine if a time interval trigger condition has occurred. 
     In the first stage of the pipeline, the processing circuit subtracts the two time stamps from the current and the previous event to determine the time interval between events being measured. The second stage checks the measurement result against minimum and maximum limits and determines which bin the measurement belongs in. The limit testing determines if the measurement fits the histogram limits and also yields the data required to perform measurement triggering on time intervals. The third stage of the pipeline increments the appropriate histogram bin in RAM. The first and third stages of the pipeline are themselves pipelined in substages. 
     To facilitate pipelining in storing the histogram results, the circuit uses dual port RAMs to achieve a fast data accumulation rate. When histogramming, the stored bin data must be incremented each time a new measurement occurs. The third pipeline stage read, increment, write operation is pipelined in substages by adding a latch in the data incrementing loop for the Dual Port RAM. The latch also provides a way of avoiding access conflicts when the same bin is incremented repeatedly.

Abstract: An adaptive polarization combining system (100) automatically adjusts the polarization of a polarization diverse antenna (101) to match that of the incoming RF signal, thereby maximizing the received signal-to-noise ratio. Signals from the orthogonally polarized ports (A, B) of the antenna (101) are passed through a variable combiner circuit (50) which is adjusted to maximize the combined signal at a single output port (64). Sample signals (A′, B′) from each antenna port (A, B) are pro­vided to a calibration circuit (150) which obtains phase and amplitude information from the two orthogonally polarized received signals and uses this information to control the combiner circuit phase shifters (52, 54, 58, 60) to adapt the combiner circuit (50) to the polarization of the received signals. Therefore, the combining system (100) can rapidly adapt electronically to polarization changes in the received signals.
