Title: Conversion of internal processor register commands to i/o space addresses
Inventor: STAMM REBECCA L
IPC: F02B75/02
Filed: 1991-06-27
Abstract: CONVERSION OF INTERNAL PROCESSOR REGISTER      COMMANDS TO I/O SPACE ADDRESSES                  ABSTRACT OF THE DISCLOSURE       A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. Macroinstruction pipelining is employed (instead of microinstruction pipelining), with queueing between units of the CPU to allow flexibility in instruction execution times.  A wide bandwidth is available for memory access; fetching 64-bit data blocks on each cycle.  A hierarchical cache arrangement has an improved method of cache set selection, increasing the likelihood of a cache hit.  A writeback cache is used (instead of writethrough) and writeback is allowed to proceed even though other accesses are suppressed due to queues being full.  A branch prediction method employs a branch history table which records the taken vs. not-taken history of branch opcodes recently used, and uses an empirical algorithm to predict which way the next occurrence of this branch will go, based upon the history table.  A floating point processor function is integrated on-chip, with enhanced speed due to a bypass technique; a trial mini-rounding is done on low-order bits of the result, and if correct, the last stage of the floating point processor can be bypassed, saving one cycle of latency.  For CAL type instructions, a method for determining which registers need to be saved is executed in a minimum number of cycles, examining groups of register mask bits at one time.  Internal processor registers are accessed with short (byte width) addresses instead of full physical addresses as used for memory and I/O references, but off-chip processor registers are memory-mapped and accessed by the same busses using the same controls as the memory and I/O.  If a non-recoverable error detected by ECC     circuits in the cache, an error transition mode is entered wherein the cache operates under limited access rules, allowing a maximum of access by the system for data blocks owned by the cache, but yet minimizing changes to the cache data so that diagnostics may be run. Separate queues are provided for the return data from memory and cache invalidates, yet the order or bus transactions is maintained by a pointer arrangement.  The bus protocol used by the CPU to communicate with the system bus is of the pended type, with transactions on the bus identified by an ID field specifying the originator, and arbitration for bus grant goes one simultaneously with address/data transactions on the bus.

IPC: E21B47/10

Abstract: Gas influx into a wellborer called a "kick", is detected by different, yet complementary methods during active drilling of the borehole.  The first method is based upon the existence of standing wave patterns generated by pressure oscillations of the drilling rig mud pumps.  Such standing wave patterns form time sequences of maxima and minima as a gas slug moves upwardly in the annulus. The time between such peaks of such oscillations is measured and forms the basis for generation of one kick signal. A continuous increase in the phase between annulus and drill string standing waves forms the basis for another standing wave kick signal.  The second method uses acoustic signals from a downhole source near the bottom of the borehole which are transmitted at different speeds in the annulus mud and in the interior drill string mud, where the annulus mud may be gas cut.  A difference in arrival time between the signals is determined, and if large enough, causes a second kick signal to be generated. A third method may be used where at least two drilling pumps are used i the drilling system.  Such method determines the total travel time, from standpipe to drill string and up the annulus, of a beat frequency pressure wave caused by slightly different frequencies of the two pumps.  An alarm signal is generated if the total travel time is greater than a computed threshold.

Title: Quick-response accelerometer
Inventor: BEHR LEONARD W
IPC: H01H35/14
Filed: 1991-07-30
Abstract: ABSTRACT    An acceleration sensor comprises a tube formed of an electrically-conductive, nonmagnetic material; an annular magnetically-permeable element, such as a iron washer, encircling a longitudinal portion of the tube; a magnetic sensing mass in the tube which magnetically interacts with the washer so as to be magnetically biased towards a first or "rest" position in the tube characterized in that a  longitudinal portion of the sensing mass  is situated within the portion of the tube encircled by the washer, the sensing mass being displaced from its rest position in the tube towards a second position therein in response to an accelerating force exceeding the magnetic bias thereon; and a switch operated by the sensing mass when the sensing mass is displaced to its second position in the tube.  The instant accelerometer features a low threshold magnetic bias of the sensing mass to provide a quickened sensing mass response to acceleration inputs of short duration; and a magnetic bias which increases in a substantially linear manner with increasing sensing mass displacement from its rest position towards its second position within the tube.

Abstract: An ultrasonic sensor for use in an ultrasonic micro spectrometer includes a concave surface transducer having a concave ultrasonic wave transmitting/receiving surface and a plane transducer having a plane transmitting/receiving surface.  The concave surface transducer is capable of transmitting converging ultrasonic waves toward a specimen, wherein the waves are reflected from the surface of the specimen and are received by the plane transducer which outputs electric signals corresponding to the intensity of the reflected ultrasonic waves. Based on a signal output from the ultrasonic sensor, a spectroanalyzer forms a distribution of spectral intensity indicating the intensity of the reflected wave as a function of frequency.  A tracking generator further forms a distribution of spectral phase indicating the spectral phase of the reflected waves as a function of frequency.  Either the distribution of spectral intensity or of spectral phase can effectively be analyzed for evaluating elastic characteristics and structure of a specimen.
