At least one transmitting message transmitted via at least one enterprise service bus by a plurality of application programs is intercepted. The at least one transmitting message includes at least one request message. The at least one request message is obtained by filtering the at least one transmitting message. A client and a server of each of the at least one request message are obtained. A checksum of each of the at least one request message is calculated to obtain a message identification of each of the at least one request message.

Abstract: A technique generates application-level dependencies in one or more virtual machines (VMs). An intercepting module in a VM monitor intercepts a guest operation system (OS) at TCP send and close related operations. An introspecting module in the VM monitor performs VM introspection for TCP connection and thread information by checking running thread and processing socket kernel objects. It generates an application trajectory and exports application dependencies from the application trajectory for a selected application.

Abstract: A portable fragrance disperser adapted for use with a fragrance cartridge includes a housing, a fan unit, and an air guide assembly. The housing is formed with a component containing space, and has a fragrance inlet, a fragrance outlet and an air inlet, all of which are in fluid communication with the component containing space. The fragrance inlet is adapted to engage the fragrance cartridge. The fan unit is mounted in the component containing space, and is operable so as to mix air flowing into the housing via the air inlet with the scent of the fragrant material coming from the fragrance inlet to result in a fragrant air stream that is released at the fragrance outlet. The air guide assembly includes a guide tube coupled to the housing at the fragrance outlet for guiding flow of the fragrant air stream released from the housing.

Abstract: A computer casing includes a case body and a heat-dissipating device. The case body has a side wall formed with a series of expansion slots. The heat-dissipating device is adapted for dissipating heat generated by a component inside the case body, and includes an impeller housing and a fan impeller. The impeller housing is mounted on the side wall inside the case body such that the impeller housing is juxtaposed with one of the expansion slots. The impeller housing is formed with an air inlet and an air outlet. The fan impeller is mounted in the impeller housing, and is operable so as to generate air currents that flow from the air inlet through the air outlet for cooling the component in the case body.

Abstract: A heat-dissipating device is adapted for use with a portable computer that includes a host module and a display module connected pivotally to the host module. The heat-dissipating device includes a support member and a fan unit. The support member includes a box body having a bottom wall and a peripheral wall that extends upwardly from a periphery of the bottom wall. The box body is formed with an air inlet and an air outlet. The peripheral wall is adapted to support the host module of the portable computer thereon. The fan unit is mounted on the box body, and is operable so as to draw air into the box body through the air inlet and so as to discharge the air in the box body through the air outlet.

Abstract: A heat-dissipating device is used to dissipate heat generated by a component in a computer casing, and includes a flexible tubular conduit and a fan unit. The tubular conduit is adapted to be disposed in the computer casing, and has a first end adapted to be connected to the computer casing such that the first end of the tubular conduit is registered with and communicates fluidly with a vent hole in the computer casing, and a second end opposite to the first end. The fan unit is mounted on the second end of the tubular conduit, and is adapted to be mounted in the computer casing such that the fan unit confronts the component in the computer casing. The fan unit is operable so as to generate air currents that flow through the tubular conduit for cooling the component in the computer casing.

A rotor includes a rotor shaft extending into the mounting tube. First and second bearings are sleeved on the rotor shaft, and each has an abutment plate, and a peripheral flange that extends axially from the abutment plate, that slidably contacts the inner wall surface of the mounting tube, and that cooperates with the rotor shaft and the abutment plate to define a lubricant-receiving reservoir thereamong. Two annular bearing-covering caps are sleeved on the rotor shaft to sealingly cover the lubricant-receiving reservoirs in the first and second bearings.
