摘要： A computer implemented method and apparatus for mounting a user removable media in a computer system includes acquiring a media identifier input and a function identifier input from a user of the computer system. The media identifier input identifies the user removable media, and the function identifier input specifies a mounting operation to be performed on the user removable media. The media identifier and the function identifier inputs are processed to access a system media interface of the computer system, for example, by converting the media identifier input to a physical path of the user removable media in the computer system, and determining if the physical path of the media identifier input is valid within the computer system. A simulated media event is generated to mount the user removable media in the computer system. If desired, a determination may be made whether the user has valid permission to control the user removable media identified by the media identifier input. This may be performed by reading a media permission level associated with the user removable media identified by the media identifier input, reading a user permission level associated with the user, and comparing the media permission level to the user permission level.

摘要： The invention provides an under aircraft load carrying and release device with possibility of orientation of the load with respect to the aircraft by using an eccentric and of fixing on fixed supports by raising the hooks. The device comprises a mechanism with three roller escapements, one for each hook and a third one for releasing a tripping spring, the rollers and the loaded articulations being mounted on ball or needle bearings and thus allowing heavy loads to be released by means of an electromagnet of small volume and low consumption.

摘要： A multiphase stepper motor is used to position the printhead of a thermal printer. Movement of the printhead is controlled by sequentially enabling adjacent phases of the stepper motor. While enabled, the current flowing in any phase is controlled by a switching regulator. During those periods when the switching regulator is turned off, the decaying current in an enabled phase flows through a flyback diode, the power loss associated with the flyback diode circuit being very small. Accordingly, the decay of current in the inductive phase winding is primarily controlled by the losses of the winding itself. When a phase is disabled, however, and the next phase enabled by the enabling means of the controller, it is desired that the inductive current in the disabled phase rapidly decay to zero. This is accomplished by a circuit in the decaying current path and in series with the flyback diode, this circuit being switchable to a high loss condition during the decaying phase of the inductive current. In the preferred embodiment, this circuit is configured so as to maintain the voltage across the disabled winding substantially constant during the period of current decay. Accordingly, the current decays to zero in a linear fashion.
