Cloning a local environment is described. Cloning a local environment can enable sharing the environment during pair programming. Cloning can have other uses as well. A server or other computer may maintain a clone environment of a first client apart from a second client such that the cloned computing environment, mimicking the environment of the first client, may be maintained on behalf of and used by a second client.

A vehicle is mounted with a drive device provided with a plurality of rotating electrical machines, and a drive unit driving the plurality of rotating electrical machines. A drive control device for the vehicle includes an electrical leak detector detecting electrical leak in the drive device, and a control device. The control device identifies an electrical leak location by receiving a result of the detection made by the electrical leak detector, and determines which rotating electrical machine out of the plurality of rotating electrical machines is allowed to operate when the vehicle is driven next time, in accordance with the electrical leak location, while the vehicle is stopped.

An insulation resistance drop detector includes a pulse generator that applies a pulse signal to a series circuit in which a detecting resistor, a coupling capacitor, and an insulating resistance are serially connected. In a state where the pulse signal is applied to the series circuit, control circuit detects a pulse-like divided voltage occurring at a node by a voltage detecting circuit via a bandpass filter, to thereby sense a drop of an insulation resistance. Further, the control circuit senses a failure of the insulation resistance drop detector itself when the voltage detected by the voltage detecting circuit is maintained at least at a prescribed voltage exceeding a plurality of cycles of the pulse signal. Thus, the insulation resistance drop detector having a failure self-diagnosis function is realized by a simple configuration.

The present invention provides a polarization dependency-free, gain-saturated high function semiconductor optical amplifier and optical module at industrially low cost. The gist of the present invention is to structurally separate the optical signal propagating waveguide from another optical waveguide which serves as a lasing optical cavity for optical amplification in such a manner that the two optical waveguides are formed in the same plane but not parallel to each other.
