Abstract: A subterranean formation is tested in a minifrac type of test to determine the fracture parameters. Fluid is injected to generate a fracture and then the pressure of the fluid is monitored over a period of time, and from its decline a fluid leak-off exponent is established. From this, fracture parameters are determined.

Abstract: It is known for motors to be controlled in the so-called chopper mode using a voltage of constant amplitude, whose pulse width is modulated. The polarity of in each case one motor winding is reversed for braking or for reversing the rotation direction. It has been found that, in many other applications, for example in the case of a capstan motor of a video recorder, the braking takes place too quickly. The object is to create a method which uses the chopper mode and enables a defined braking effect for the motor. Intermittent polarity reversal of the the winding is carried out at time intervals which are separated by pauses and whose duration is dependent on the respectively desired braking effect. Especially for the capstan motor in a video recorder. <IMAGE>

Abstract: A novel method and system are disclosed for handling transport overhead on a ring network. The system (Fig. 5a) includes a ring network having a plurality of network elements (NE0, NE4, NE2, NE3, NE6 and NE5) communicating a signal along the network. In one embodiment, a method (Fig. 6a) is provided for restoring transport overhead along the ring network. This method includes designating a first of the plurality of network elements as a master network element and inserting a first transport overhead break on the ring network by the master network element (Fig. 5b, 40). The method further includes detecting a failure of the signal by a second network element (Fig. 6a, step 46) and inserting a second transport overhead break on the ring network by the second network element in response to the detection of a failure (Fig. 6a, step 48). Finally, the method includes removing the second transport overhead break under the direction of said master network element (Fig. 6a, steps 60, 66, 70, 78-86). 
     Another method of restoring transport overhead is disclosed which also includes the steps of designating a first of the plurality of network elements as a master network element and detecting a failure of the signal by a second network element. In addition, the method includes the step of transmitting a count (K1 byte) to the master network element by the second network element in response to the step of detecting a failure. In addition, the count is incremented each time it passes through a network element other than the first and second network elements. Finally, the count is received by the master network element.

Abstract: After a number of optical fibers (20) are inserted into a tubular member (10) of a shape memory alloy, the tubular member is returned to its memorized shape by heating to reduce a cross-sectional area of a reception space (11) of the tubular member, thereby uniting the optical fibers received in the tubular member. In a modified form of the invention, a number of optical fibers (20) are inserted into a reception space (11K) between two tubular members (10K₁, 10K₂) at least one of which is made of a shape memory alloy, and then the one tubular member is heated to be returned to its memorized shape to reduce a cross-sectional area of the reception space between the two tubular members, thereby uniting the optical fibers. In another modified form of the invention, a number of optical fibers (20) are inserted into a reception space (41) formed between an inner periphery of a tubular member (40) and a partition plate (45) of a shape memory alloy, and then the partition plate is heated to be returned to its memorized shape to reduce a cross-sectional area of the reception space, thereby uniting the optical fibers.

Abstract: A circuit automatically changes the gain in a PLL for driving a motor of the type having a motor speed signal that indicates the speed of motor rotation. The circuit includes a phase detector for sensing a phase difference between the motor speed signal and a reference frequency and for producing an output signal of duration proportional to the sensed phase difference. A counter counts clock pulses throughout the duration of the output signal, and a motor driving circuit drives the motor in response to the count reached by the counter. A source of clock pulses provides clock signals at first and second frequencies, the second frequency being lower than the first frequency, and a lock range sense circuit produces a sense signal output that indicates when the PLL is within a predetermined phase difference range. A circuit responsive to the sense signal output selectively applies the first frequency to clock the counter when the PLL is within the predetermined phase difference range, and to apply the second frequency to clock the counter when the PLL is operating outside of the predetermined phase difference range.

Abstract: A host computer including a posted write cache for a disk drive system where the posted write cache includes battery backup to protect against potential loss of data in case of a power failure, and also including means for performing a method for determining if live data is present in the posted write cache upon power-up. The posted write cache is further mirrored and parity-checked to assure data validity. Performance increase is achieved since during normal operation data is written to the much faster cache and a completion indication is returned, and the data is flushed to the slower disk drive system at a more opportune time. Batteries provide power to the posted write cache in the event of a power failure. Upon subsequent power-up, a cache signature previously written in the posted write cache indicates that live data still resides in the posted write cache. If the cache signature is not present and the batteries are not fully discharged, a normal power up condition exists. If the cache signature is not present and the batteries are fully discharged, then the user is warned of possible data loss. A configuration identification code assures a proper correspondence between the posted write cache board and the disk drive system. A mirror test executed to verify data validity. Temporary and permanent error conditions are monitored so that posted write operations are only enabled when error-free operation is assured.

Abstract: A method and system generate performance data relating to the efficiency of an organization and include the steps of and instructions for describing a plurality of performance variables associated with the organization. The performance variables describe measurable properties of the organization. The invention further maps each of the performance variables to a normalized performance variable mapping that has a neutral value and at least one inflection point of the performance variable within a normalized range of values. Each inflection point describes effects of the normalized performance variable in changing from a positive influence to a negative influence on the organization's efficiency. Then the invention assigns a weighting factor to each of the normalized performance variables to produce a plurality of weighted normalized performance variables. The method and system calculate the efficiency of the organization as a function of the plurality of weighted normalized performance variables. The method and system further include the use and maintenance of instruction tables for identifying interactions among the various performance variables.
