Abstract: Simplified and insensitive to ambient condition mechanical bi-directional fiber-optic switch that can work in fire and explosion hazardous environment. The switch houses a sensitive element—a length of single-mode optic fiber and a bending device, which being activated provides specific bending of the optic fiber that introduces high attenuation of an optic signal so completely terminating light signal transmission. The switch can be configured as single on/off switch or multi-channel one.

Abstract: A fiber optic polarimetric strain sensor and associated data acquisition system capable of all-optical measurements of physical parameters, such as structural strain, gas and liquid pressure, acceleration and vibration, gas and liquid flow rate, and force without fire and explosion hazards associated with conventional strain gage technologies, such as resistance foil strain gages. The polarimetric strain sensor houses a sensitive element—a length of single-mode optic fiber—changing polarization of a single-mode optical signal running in the fiber under some mechanical effects, specifically twisting and radial compressing. A multi-channel time division multiplexing data acquisition system indicates the polarization state deviation caused by the strain, so allow measuring the parameters. The invention may be embodied for measurements of any phenomenon that can be transformed in stress on an optical fiber.

The interrogator attached to a small arm, such as a rifle, includes a FO laser diode and FO receiver, which are connected to FO graded-index lens attached to sight of the small arm via a single-mode optic fiber, an electronic unit positioned in any convenient place of the small arm, and an alarm LED attached to the sight together with the lens. The transponder, which “a friendly target”—a soldier—is equipped with, contains a set of transmitter-receiver unit and an electronic unit that are mounted on a harness attached to soldier's helmet. This IFF system, when a friendly soldier is targeted, starts visual alarm signal for the shooter and sound signal for the “friendly target” so preventing “friendly fire”.

Abstract: Novel class dynamoelectric machines utilizing “tangential induction” phenomenon—the specific e.m.f. induction, which appears in tangential conductors—is introduced. Alternating-current dynamoelectric machines of this invention house an axially-polarized multi-polar permanent magnet rotor and stator winding having tangentially arranged semi-ring conductors. The rotating permanent-magnet rotor induces current in tangential semi-ring conductors, which, according to Ampere law, could not produce a resistance moment applied to the rotor because the vector of conductor-field velocity is directed along the conductor, and, therefore, such vector orientation does not produce any tangential force. The invention has been successfully embodied in number of “tangential-induction dynamoelectric machines” including multi-phase ones. These dynamoelectric machines can be inverted and work as alternating-current asynchronic electric motors.
