Abstract: A replaceable battery module for a battery-powered device includes a protective conductive canister sized to receive an electric storage battery. A conductive contact extends through an aperture of the canister for contacting a first terminal of the battery. A second terminal of the battery is electrically contacted by the canister. A preferred configuration of the canister and contact allow both of the terminals of the battery to be accessed from one end of the battery module. A seal is positioned between the canister and the contact for electrically insulating them and for sealing the aperture to prevent leakage of the battery beyond the battery module. A socket for electrically contacting the battery module is formed by a power input terminal assembly mounted within a battery-receiving cavity of a battery-powered device.

Abstract: A telescopic sight is provided that includes an integral mounting bar for connection to a barrel of a firearm and integral auxiliary equipment mounting features for mounting auxiliary equipment onto the telescopic sight. The auxiliary equipment mounting features facilitate the mounting of multiple devices that allows for quickly alternating between different aiming devices or to simultaneously use multiple aiming devices. Clamp assemblies cooperate with the mounting bar to secure the telescopic sight to the firearm and provide adjustment of the height position of the telescopic sight. The clamp blocks are adapted to fit onto a mounting rail of a firearm. The mounting features are universal and require no post-mounting adjustment to accurately align the auxiliary equipment.
