Deterrent device accessory

Abstract

Accessories for a deterrent device having an accessory mounting projecting from a support by a mounting projection distance along a mounting projection axis are provided. In one aspect, an accessory has an electronics module having an electronic system and a mounting portion adapted to engage to the accessory mounting with the mounting portion extending along the mounting projection axis by an accessory lateral projection distance when engaged to the accessory mounting and with the mounting portion positioning the electronics module so that the electronics module to extends along an axis parallel to the orthogonal axis by a lateral extent and is positioned by the mounting adjacent to the accessory mounting with the mounting portion having an accessory mounting projection distance is less than the projection mounting projection distance.

What is claimed is: 
     
         1 . An accessory for a deterrent device having an accessory mounting projecting from a support by a mounting projection distance along a mounting projection axis; the accessory comprising:
 an electronics module having an electronic system;   a mounting portion adapted to engage to the accessory mounting with the mounting portion extending along the mounting projection axis by an accessory lateral projection distance when engaged to the accessory mounting and with the mounting portion positioning the electronics module so that the electronics module to extends along an axis parallel to the orthogonal axis by a lateral extent and is positioned by the mounting adjacent to the accessory mounting;   wherein the mounting portion has an accessory mounting projection distance is less than the projection mounting projection distance.   
     
     
         2 . The accessory of  claim 1 , wherein the lateral projection distance is smaller than 75% of the lateral projection distance. 
     
     
         3 . The accessory of  claim 1 , wherein the lateral projection distance is smaller than about 33% of the lateral projection distance. 
     
     
         4 . The accessory of  claim 1 , wherein the electronic system emits a beam of low divergence light and wherein the electronic system is positioned along the orthogonal axis within the first extent to reduce an extent of parallax between the discharge axis of the deterrent device and the beam. 
     
     
         5 . The accessory of  claim 1 , wherein a surface of the support is directed at least in part away from the direction along which accessory mount extends from support along the projection axis and wherein the mounting positions the electronics module at least in part adjacent to the surface. 
     
     
         6 . The accessory of  claim 1 , wherein a surface of the support to which the accessory mount is joined is directed at least in part away from the direction along which accessory mount extends from support, wherein the electronics module extends along an axis parallel to the projection axis by a maximum extent that is greater than the combination of the mounting projection distance and the accessory lateral projection distance an and wherein the mounting positions the electronics module at least in part adjacent to the surface. 
     
     
         7 . The accessory of  claim 1 , wherein the mounting portion includes at least a part of a sensing system of the electronic system adapted to detect the presence of a portion of a human body proximate to an outer surface of the mounting portion. 
     
     
         8 . The accessory of  claim 1 , wherein the mounting portion includes at least a part of an external interface system of the electronic system that can be sensed by a user. 
     
     
         9 . The accessory of  claim 1 , wherein the deterrent device comprises a firearm that discharges projectiles through a barrel orthogonal to the projection axis and the wherein the mounting is shaped to enable heated air to flow through the mounting.
