Abstract: A vehicle proximity warning system includes a first device carried by a first vehicle and comprising a first transceiver and a first warning device, and a second device carried by a second vehicle and comprising a second transceiver and a second warning device. The first device determines proximity of the first vehicle relative to the second vehicle and generates a warning signal with the first warning device when the proximity is within a first predetermined distance. The second device determines proximity of the second vehicle relative to the first vehicle and generates a warning signal with the second warning device when the proximity is within a second predetermined distance.

Abstract: Systems and methods for presenting incident information provided by video devices and electronic weapons. Information may be selected for presentation by a machine or a human operator. Information from video devices and/or electronic weapons may be temporally aligned (e.g., synchronized) for presenting events that occurred in a temporally related manner. Information for aligning may be collected by a server and/or a video device.

Abstract: An electronic weapon with an installed deployment unit, from which at least one tethered electrode is launched, provides a stimulus current through a target to inhibit locomotion by the target. The wire tether, also called a filament, conducts the stimulus current. The one or more electrodes, according to various aspects of the present invention, perform one or more of the following functions in any combination: binding the filament to the electrode, deploying the filament from the deployment unit, coupling the electrode to the target, and distributing a current density with respect to a region of target tissue and/or a volume of target tissue. For an electrode that includes a body and a spear, the spear may be implemented with conductive rings or with materials that include integrated conductive and insulative substances (e.g., conductive fibers in insulative composite material). Relatively high electric field flux density at a tip of the spear may be reduced or avoided by practice of the invention.

Abstract: An apparatus, according to various aspects of the present invention, produces contractions in skeletal muscles of a target to impede locomotion by the target. The apparatus is used with a provided deployment unit that deploys an electrode away from the apparatus. The electrode conducts a current through the target. The apparatus includes a terminal; a producing sub-system for producing an electric arc to warn the target without conducting a current through the target; a conducting sub-system for conducting the current in series through the terminal and through the target; an initiating sub-system for initiating deployment of the electrode; and an operator interface. The operator interface facilitates selecting one or more cartridges of a set of cartridges to provide a stimulus signal to a target and/or display an arc.

Abstract: An apparatus interferes with voluntary locomotion of a target by conducting a current through the target. The apparatus includes a current delivery circuit, a detector, and a processor. The current delivery circuit delivers the current in accordance with a goal for causing pain or skeletal muscle contractions that interfere with voluntary locomotion by the target. The detector detects the current delivered through the target to provide a result. The processor adjusts the goal in accordance with a binary search in response to the result.

Abstract: An electronic weapon may be used with a unit for deployment to cause skeletal muscle contractions in a human or animal target. The unit for deployment when electrically coupled to the electronic weapon, may include at least two electrodes, an indicator, and a propellant for deploying the electrodes to enable delivery, through the target, of a stimulus current to incapacitate the target by causing contractions of the skeletal muscles of the target. The indicator indicates, to the electronic weapon, indicia of a first property of the unit for deployment prior to operating the propellant, and indicia of a second property of the unit for deployment after operating the propellant. Another unit for deployment includes at least two electrodes, an indicator, and a stimulus signal generator, coupled to the electrodes to enable delivery, through the target, of a stimulus current to incapacitate the target by causing contractions of the skeletal muscles of the target.

Abstract: An apparatus for interfering with locomotion of a target by conducting a current through a load that includes an ionizable path. The apparatus includes, according to various aspects of the present invention, an energy source, an ionization detector, a charge detector, a controller, and a pulse generator.

For each pulse of the plurality, the pulse generator receives the respective quantity of energy from the energy source, provides in response to the quantity of energy a respective voltage to ionize the ionization path, and provides the current through the load. The charge detector detects a charge provided through the load. The processor sets the voltage for charging for a next pulse in response to the charge detected by the charge detector.
