System of automatic operability control and fault diagnostics of electronics

System comprises a unit being controlled which consists of a controlled unit identifier, a set of software-controlled sources of input test signals, a set of response signal parameters' meters, a computer, a replaceable adapter including an adapter identifier; the identifier inputs are connected to the outputs of supplementary test channels at software-controlled sources of input test signals, and the identifier outputs are connected to the inputs of the supplementary channels of the response signal parameters' meters.

Method for controlling condition of multivariate object

Invention refers to the sphere of measurement technologies and can be used to control and analyse the condition of complex multivariate objects being the elements of the connection systems and automation. The result is achieved by the identification of abnormal changes of condition's characteristics of one of the complex of identical elements of multivariate objects during in functioning by setting the standard values and allowed deflections of the characteristics of the elements' condition of the multivariate object, measuring current values of the parametres under control, calculating the current values of the characteristics of the elements' condition of the multivariate object and comparing them with the given standard values and allowed deflections.

Multimode device and method of mobile communication, involving receivers operating simultaneously

Invention concerns communication technology. To achieve the objective, the device includes two separate receivers related to two different radio communication technologies, and multimode channel selection circuit. First and second receivers are simultaneously receiving first signal via first channel and second signal via second channel respectively. Then multimode channel selection circuit obtains information on first cell selection from the first signal and information on second cell selection from the second signal, and further selects appropriate channel to be set, according to the first and second cell selection information. The method involves receiving first and second signals via simultaneously operating receivers, obtaining information on the first and second cell selection, and selection of appropriate channel to be set, according to the first and second cell selection information.
