Disclosed is system for monitoring data changes during a data replication process. The system includes a modeling module configured to select tables and fields to be monitored during execution of the data replication process, a trigger module configured to track changes of data being generated during execution of a program by inserting triggers into a destination system at the start of a program execution and then dropping the trigger at the end of program execution, a snapshot module configured to track changes of data being generated during execution of a program by generating a snapshot of data at the beginning and the end of program execution, and a report module configured to generate a report indicating changes in data based on the changes in data indicated by the triggers and based on the changes in data indicated by the snapshots of data.

System and method are disclosed for synchronization of a transmitting device and a receiving device that communicate with each other via pulse modulation. The synchronization technique entails the transmitting device sending one or more quasi-periodic pulse sequences to the receiving device. A quasi-periodic pulse sequence is based on a substantially periodic pulse sequence, and may include some non-periodic pulses or not include some periodic pulses. The transmitting device may transmit frames each including a preamble that comprises one or more quasi-periodic pulse sequences, and a data payload that may comprise data. The receiving device receives the signal, generates samples of the signal, and detects the quasi-periodic pulse sequences in the received signal by analyzing samples based on a sample associated with a pulse and the period associated with the substantially periodic pulse sequence. The receiving device is further able to detect frames based on the detection of the sequence, and extract data therefrom.

Systems and methods of managing memory devices provide for reduced power consumption and better thermal management through enhanced memory throttling. In one embodiment a memory unit includes a memory device and a temperature measurement module coupled to the memory device. The temperature measurement device measures the internal temperature of the memory device. Memory throttling can therefore be implemented based on more accurate measurements and with a much shorter response time.

A coating is described for an airfoil blade component. The coating comprises a cermet material and has, when applied to the rotor blade, a compressive residual stress greater than about 60 ksi. In another embodiment, the compressive residual stress of the coating is in the range of approximately 90-110 ksi.

A method of wireless communication is disclosed that includes receiving a plurality of samples from a transmission of a known sequence; identifying a peak position in the known sequence based on a correlation of the plurality of samples and the known sequence; and adjusting the identified peak position based on an offset. An apparatus for performing the method is also disclosed herein.

A system for supporting a shroud used in an engine has a shroud positioned radially outboard of a rotor, which shroud has a plurality of circumferentially spaced slots; a forward support ring for supporting the shroud; the forward support ring having a plurality of spaced apart first tabs on a first side for functioning as anti-rotation devices; the forward support ring having a plurality of spaced apart second tabs on a second side; and the second tabs engaging the slots in the shroud and circumferentially supporting the shroud.
摘要:
An apparatus for data communication that receives a plurality of pulses from a remote communications device, determines a pulse puncturing rate based on the pulses, and punctures or discards subsequent pulses based on the pulse puncturing rate. During intervals when punctured pulses are expected, the apparatus operates in a lower power consumption mode for the purpose of conserving power. In another aspect, a receiving apparatus determines the pulse puncturing rate based on received pulses, and transmits the pulse puncturing rate information to a transmitting apparatus. In response, the transmitting apparatus sends a subset of the pulses it would have transmitted based on the pulse puncturing rate. Because the receiving apparatus receives fewer pulses (e.g., a subset), the receiving apparatus may operate in a lower power consumption mode for longer periods in order to conserve power. Similarly, because the transmitting apparatus sends fewer pulses, it may also operate in a lower power consumption mode for longer periods.
摘要:
A reverse flow combustor has an inlet end. A flowpath extends downstream from the inlet end through a turn. The turn directs the flowpath radially inward and reversing an axial flow direction. A large exit duct (LED) is along the turn. A small exit duct (SED) is along the turn and joined by a joint to a mounting structure to resist separation in a first axial direction. The joint comprises: a first surface on the SED facing partially radially inward; and a mounting feature engaging the first surface.
摘要:
A shroud suitable for use in combination with an adjacent rotor blade includes a leading portion comprising a first thickness, and a trailing portion adjacent to the leading portion and comprising a second thickness, wherein the second thickness is less than the first thickness so that stiffness in the leading portion is greater than in the trailing portion and radial expansion by thermal growth of the leading portion of the shroud is constrained.
