Abstract: An injection device (10) includes a lower housing (18), a sleeve (32) supported by the lower housing, and a syringe spring (34) received within the sleeve. The spring supports a syringe (12). A needle guard (26) is proximally slidable relative to the lower housing from a first position, concealing the syringe needle (12b), to a second position. A needle guard spring (27) biases the needle guard distally relative to the lower housing. An upper housing (16) is distally slidable relative to the lower housing from a pre-use position to a dispensed position. Movement of the needle guard from the first position to the second position extends the distal tip of the needle distally beyond the needle guard by a first distance. Subsequent distal movement of the upper housing relative to the lower housing from the pre-use position toward the dispensed position advances the distal tip of the needle distally further beyond the needle guard by a second distance.

Abstract: An electronic weapon has an installed deployment unit from which an electrode is launched. The electrode is tethered to the deployment unit by a wire or filament. According to various aspects of the present invention, a wire-tethered electrode for launching from a weapon, for impacting clothing of a human target, and for conducting a stimulus signal through the target to inhibit locomotion by the target includes an insulated wire, a spear, and a body. The wire mechanically couples the electrode to the weapon. The spear lodges in the clothing. The body has an interior. The interior confines the wire against the spear so that the stimulus signal ionizes air in a gap between an uninsulated end of the wire and the spear, and ionizes air between the barb and tissue of the target to facilitate conducting the stimulus signal through the spear and through the target.

Abstract: An electronic weapon has an installed deployment unit from which an electrode, tethered by a filament, is launched. According to various aspects of the present invention, the deployment unit includes a housing, two filaments stored in the housing prior to launching, and two electrodes, each coupled to the end of one of the filaments. A propellant in the housing launches the electrodes responsive to the launch device. In operation, an end portion of each filament experiences a tensile stress during launching. The tensile stress follows a nonlinear path along a surface of an undulation of an interior of the respective electrode.

Abstract: An electronic weapon has an installed deployment unit from which an electrode, tethered by a filament, is launched, according to various aspects of the present invention. The electronic weapon provides a stimulus signal through a target to inhibit locomotion by the target. The electrode includes a body and a spear. The body has an interior. The spear has a tang. During assembly of the electrode, the filament is positioned in the interior. The tang is positioned in the interior over the filament. The tang is then mechanically coupled to the body, securing the filament in the interior. After assembly, applying a force along the filament results in friction between the filament and the interior. The interior of the body may include an undulation.

Abstract: A modular air conditioning system comprises a self-contained refrigeration power cell and a remotely located heat exchanger coupled by a low-pressure refrigerant circuit. The refrigeration power cell comprises a compressor, a condenser, an expansion device, and an evaporator, which are serially coupled to form a high-pressure closed refrigeration circuit. The low-pressure circuit thermally interfaces with the condenser to remove heat from the high-pressure circuit. This heat exchanger is adapted to mount in proximity to or be integrated with the radiator. Alternatively, this circuit thermally interfaces with the evaporator to remove heat from the low-pressure refrigerant. This heat exchanger is adapted to mount in the cabin of the vehicle. When the low-pressure circuit thermally interfaces with the evaporator, the low-pressure circuit may further include a cool box for storing items to be refrigerated. Preferably, the cool box and heat exchanger may each be operated either alone, or in combination.
