Abstract

A projectile impact simulation device comprising a housing, a mounting attachment, at least two high-voltage pins, and a shock zone. The housing has a circuit board electrically coupled to high-voltage receptacles that are configured to receive a first end of a high-voltage pin. The housing also has a back surface configured to rest adjacent to a user when the user wears the device. The mounting attachment is coupled to the back surface and configured to couple the device to the user. The high-voltage pins are embedded within the housing and configured to couple with the high-voltage receptacles. Two contact pads exposed on the back surface each have an electrical contact coupled with the high-voltage pins. When a voltage differential is applied across the contact pads, the device is configured to cause an electric arc in the shock zone. When the device is worn by a user, the electric arc shocks the user.

Dependent claims

A projectile impact simulation device, comprising:

a front housing having a circuit board and at least two conductive, high-voltage receptacles each electrically coupled to the circuit board and configured to receive a first end of a high-voltage pin therein;
a rear housing coupled to the front housing and having a back surface distal to the front housing, the back surface configured to rest adjacent to the body of a user when the user wears the projectile impact simulation device;
a mounting attachment coupled to the back surface of the rear housing and configured to directly couple the projectile impact simulation device to the user or an article of clothing worn by the user;
at least two high-voltage pins embedded within the rear housing and configured to mateably couple with the at least two high-voltage receptacles, each of the at least two high-voltage pins having a head with a convex contact surface;
and
a shock zone on the back surface of the rear housing comprising the area between at least two contact pads, the at least two contact pads exposed on the back surface of the rear housing and each of the at least two contact pads having an electrical contact extending into the rear housing, each electrical contact comprising a first portion extending in a first direction and a second portion extending from the first portion in a second direction different from the first direction such that when the second portion contacts the convex contact surface of a corresponding high-voltage pin of the at least two high-voltage pins, the electrical contact is configured to flex and exert a pushing force against the convex contact surface of the head of the corresponding high-voltage pin to maintain contact with the convex contact surface of the head of the corresponding high-voltage pin;
wherein when a voltage differential is applied across the at least two high-voltage pins, the voltage differential is carried to the at least two contact pads and wherein the projectile impact simulation device is configured to deliver a maximum shock having an average current of less than 500 milliamps (mA) through plurality of charge pulses in the shock zone to the at least two contact pads;
and
wherein when the projectile impact simulation device is worn by the user, the projectile impact simulation device is configured to deliver an electric shock to the user through any clothing positioned between the projectile impact simulation device and skin of the user as a simulation of a projectile impact.
