An electrical discharge weapon configured as a lightweight, slim profile gun-shaped weapon which is less than one inch thick along the cartridge receiving chamber so that it can be readily placed in a police officer's uniform pocket or in a slim-line holster for easy deployment. All of the major internal components, including battery and transformer, are positioned above or behind the trigger aperture so that even with the dart cartridge in the chamber, the weapon's center of gravity is through the hand so that it is balanced and easily aimed at the target. The invention employs a specially configured chamber to receive a unique cartridge with widely separated darts. As a result, the electrodes may be also widely separated so that current will not jump the electrode gap even when the impacted darts leave a substantial gap to a suspect's skin. Thus, the present invention is more likely to be effective against suspect's wearing thick outerwear. The spent cartridge may be expelled by a spring-activated release for quick ejection and rapid reload. A bottom rail permits connection of another non-lethal device such as a mace canister for use as a secondary weapon or the attachment of tactical lighting or laser aiming devices. A push-on/push-off trigger switch is combined with a mechanical safety device to assure weapon effectiveness and safety for the police officer. Quick disconnect battery clip allows for rapid battery replacement.

An emitter layer is provided in stripes in a direction orthogonal to an effective gate trench region connected to a gate electrode and a dummy trench region isolated from the gate electrode. A width of the emitter layer is determined to satisfy a predetermined relational expression so as not to cause latch-up in an underlying P base layer. In the predetermined relational expression, an upper limit value of the width W of the emitter layer is (3500/Rspb)·Wso·exp(decimation ratio), where Rspb is a sheet resistance of the P base layer immediately below the emitter layer, Wso is an interval between the trenches, and the decimation ratio is a ratio of the number of the effective gate trench region to the total number of the trench regions. Variations in saturation current in a trench IGBT can be suppressed, and a tolerance of an Reverse Bias Safe Operation Area can be improved.

The present invention pertains to the construction of a manually operated trigger sprayer in which the sprayer housing has a reduced diameter dimension liquid discharge passage to increase the velocity of liquid flow through the liquid discharge passage, and in which the nozzle assembly has a novel configuration that securely attaches the nozzle assembly to the sprayer housing to prevent the increased velocity of liquid flow through the sprayer housing liquid discharge passage from dislodging the nozzle assembly from the sprayer housing. The novel construction of the sprayer housing and the nozzle assembly includes a resilient crossbar provided on the sprayer housing that crosses over the liquid discharge passage and a pair of resilient flanges on the nozzle assembly that engage over opposite sides of the sprayer assembly crossbar and securely attaching the nozzle assembly to the sprayer housing.

A method is provided for improving the wiping capabilities of a windshield wiper by causing the windshield wiper blade to vibrate or oscillate in a direction parallel to the longitudinal centerline of the blade during a windshield wiper sweep. The vibrating mode causes less wear on the blade due to windshield abrasion since the blade edge does not contact the same eroded point on the windshield all the time. Secondly, any debris that is caught underneath the blade is quickly ejected due to the vibrating action. In one embodiment, an electromechanical vibrating unit is secured at one or more positions to the blade, with the actuator being driven by a 12-volt source and provided with a quickie disconnect at the center of the blade support structure. The vibrating actuator may be an electromechanically drive off-centered weight, a vibrating linear actuator, an ultrasonic vibrator, or a vibrator in the form of a piezoelectric crystal, with the primary mode of oscillation translating the blade along its centerline. The result is that debris underneath the blade is thrown out, including leaf stems, leaves and particulate matter, with the periodic translation of the blade providing more uniform water removal during the wiping operation to provide clearer visibility through the windshield regardless of the amount of water on the windshield, whether it be from a sporadic sprinkle or a torrential downpour. Wiper life is extended since the blade edge's position on the windshield is constantly varied during wiper sweeps.

A water purification system performs a water purification process through physical sterilization, and at least includes a compression device and a decompression device. Water is converted into a high-pressure liquid through the compression device, and then is converted into a high-speed fluid by controlling the cross-sectional area of a spout of the decompression device, thus generating physical effects such as pressure drop and shear stress, so as to damage cell walls of bacteria in the liquid to die-off the bacteria. Therefore, purified water is obtained.
