Abstract: Data  is  transferred  from  a  host  system  to  a  subsystem connected to the host by a system bus in an efficient manner using one or more virtual first in first out (FIFO) registers in host memory and a corresponding set of virtual FIFOs located in the subsystem memory.  A transmission controller controls the transfer of data from the host FIFOs to the subsystem  FIFOs  while  the  subsystem processor  reads  and processes data from the subsystem FIFO. By accumulating data in the host FIFOs before transfer to the subsystem, overhead associated with starting and stopping data transfers over the system bus is substantially reduced.

Title: Key telephone apparatus
Inventor: HARA MASAHIKO
IPC: H04M3/38
Filed: 1994-09-28
Abstract: One of the internal key telephone sets coupled to a key telephone apparatus capable of automatic call distribution operates as a supervisor and other operate as agents.      Under the automatic call distribution, the statuses of the agents and their number are stored in a memory. The stored statuses of the agents are informed to the supervisor.      Each key telephone set has a display unit. When one of the key telephone sets operates as the supervisor, the informed statuses and their number are displayed on the display unit of the supervisor. With identification data of a specific agent, the status of the specific agent is displayed on the display unit of the supervisor. To operate one of the key telephone sets as the supervisor and other the agents, first, a password is entered from one of the key telephone sets. The input password is compared with a first reference password for the supervisor and with a second reference password for the agents. When the input password is equivalent to the first password, the telephone set is registered as the supervisor. On the other hand, when equivalent to the second password, the telephone set is registered as the agent.

Title: Fuzzy logic adaptive defrost control
Inventor: SZYNAL JOSEPH M
IPC: F25D21/00
Filed: 1995-05-17
Abstract: The defrosting of a heat transfer unit of a temperature conditioning system is controlled by initiating a defrost operation when a predetermined amount of frost has accumulated on the unit during a period between defrost operations. A known desired defrost time period is required to defrost the unit when it has the predetermined amount of accumulated frost thereon. The time required to actually defrost the unit during a first defrost operation is measured to form a first defrost time. The time required to actually defrost the unit during a second defrost operation is measured, the second defrost operation is the next defrost operation following the first defrost time and forms a second defrost time. The frost accumulating period is modified in response to said first defrost time and said second defrost time.

Abstract: A fitting (10) for attachment to a tube (12) by swaging comprises a cylindrical sleeve (16) having a tapered outer surface (30) and an inner surface (20) for receiving the tube (12). A cylindrical swaging ring (22) having a tapered inner surface (50) engages the tapered outer surface (30) of the sleeve (16) such that axial movement of the ring (22) in a forward direction with respect to sleeve (16) causes the ring (22) to apply a radial force to the sleeve (16) to swage it to the tube (12). The swaging ring (22) is locked onto the sleeve (16) both before and after swaging by one or more protrusions (66, 76) on the outer surface of the sleeve (16) which cooperatively engage an annular groove (78) in the swaging ring (22). The location of the protrusions (66, 76) and groove in relation to the tapered surfaces (50, 30) of the swaging ring (22) and sleeve (16) is especially configured to provide smooth axial loading during swaging and increase tube (12) retention capabilities at the conclusion of the swaging operation.

Abstract: A method of determining the acoustic propagation velocity of an earth formation penetrated by a wellbore by processing signals from an array acoustic wellbore logging tool. The tool includes a transmitter and a plurality of receivers axially spaced apart from the transmitter. The method includes the steps of combining signals generated by ones of the receivers in response to acoustic energy propagated through the wellbore from the transmitter, to generate a synthesized signal corresponding to another one of the receivers. The step of combining includes time shifting signals from the ones of the receivers by an amount corresponding to a predetermined velocity for each propagation mode and the axial distance between the ones of receivers and the other receiver. The synthesized signal is compared to the signal generated at the other receiver in response to the acoustic energy to determine a degree of correspondence between the synthesized signal and the received signal. The values of velocity for each propagation mode are varied, a signal is again synthesized and compared to the measured signal, and these steps are repeated until the degree of correspondencereaches a maximum. The values of velocity at which the degree of correspondence is a maximum are determined to be the acoustic propagation velocities of the earth formation for each of the different modes of propagation. In a preferred embodiment of the invention, the step of comparing includes generating an object function of the difference between the synthesized signal and the received signal. The object function is minimized by the Levenberger-Marquardt algorithm to determine the values of velocity for each propagation mode.
