This invention presents a kind of ion guide device comprising multiple layers of stretched wire electrodes crossing in space. These wire electrodes are distributed along a defined ion guiding axis in the ion guide device. Each layer of wire electrodes contains at least two wire electrodes with some distance away from the guiding axis, and rotates with an angle relative to wire electrodes on neighboring layer.

Systems and methods for immobilizing a target such as a human or animal with a stimulus signal coupled to the target via electrodes provide the stimulus signal in accordance with a strike stage, a hold stage, and a rest stage. Systems include a launch device and separate projectile, where the projectile includes a battery, a waveform generator, and electrodes. The strike stage and hold stage may include pulses at a pulse repetition rate, for example, from 10 to 20 pulses per second, each pulse delivering a predetermined amount of charge, for example, about 100 microcoulombs at less than about 500 volts peak. The hold stage may continue immobilization at a lesser expenditure of energy compared to the strike stage. Because the strike stage and hold stage may immobilize by interfering with skeletal muscle control by the target's nervous system, a rest stage may allow the target to take a breath.

The invention discloses a hard reinforced concrete revetment slope biological repairing method, which is characterized by comprising the steps of: roughing a concrete revetment and constructing drainage ditches at set intervals; digging a water collecting tank on one side of the cross of the revetment and a road, reserving an opening at the joint of the drainage ditch and the water collecting tank, and constructing a watertight concrete overflow bank; filling gravels in the water collecting tank and the drainage ditches; and welding earthwork grids by high-density polyethylene stripes on the protection slope, laying gravel cushion coats in the earthwork grids, and finally pouring biological slurry.

Systems and methods for immobilizing a target such as a human or animal with a stimulus signal coupled to the target via numerous electrodes select particular electrodes to use for the stimulus signal. Subsets of electrodes may be tested by applying a test signal and monitoring the energy or charge delivered during a prescribed time. If the delivered energy or charge using a particular subset of electrodes as indicated by monitoring test pulse amplitude suitably compares to a limit, then the particular subset is selected for applying the stimulus signal. A first stimulus signal may be applied to a first subset of electrodes to prompt movement of the target toward an electrode that, when better coupled to the target as a consequence of movement of the target will provide a more effective subset of electrodes for further stimulus. For example, a projectile with closely spaced electrodes may stimulate a burning sensation to attract the target to impale the target's hand on a rear facing electrode of the projectile. Use of the rear facing electrode and one or more of the closely spaced electrodes may provide a more effective stimulus circuit through tissue of the target.
