Abstract: A firearm safety device for a firearm having a trigger and trigger guard. The firearm safety device includes first and second assemblies adapted to be secured to the firearm on opposite sides of the trigger guard to prevent access to and actuation of the trigger. The firearm safety device includes a lip disposed on at least one of the first and second assemblies for overlapping the other assembly when the safety device is secured to the firearm.

Abstract: An adapter assembly for attaching a device, such as a communication device, to a portion of a mask, such as a filter port. The assembly includes an adapter ring that attaches to the mask to effect a seal of the filter port. A mounting assembly attaches to the device and is releasably engageable with the adapter ring to support the device on the mask for rotation relative to the mask without breaking the seal of the filter port. Preferably the adapter ring attaches to the mask with a threaded connection, and the device rotates on the adapter ring with less force in a loosening direction of the threaded connection.

Abstract: A firearm safety device for a firearm having a trigger and trigger guard. The firearm safety device includes a first and second assemblies adapted to be secured to the firearm on opposite sides of the trigger guard to prevent access to and actuation of the trigger. A moveable clamp assembly includes slide member having first and second posts for receiving a portion of the trigger guard therebetween is disposed on the first assembly for slidable movement. A fastener is used to secure the slide member to the first assembly in a position to accommodate the trigger guard thereby preventing further sliding movement. Trigger guards having pins received in the apertures can be used to block access to and actuation of the trigger. An alarm is included which sounds when the firearm is moved or when an improper sequence of keys are pressed in an attempt to unlock the device. The alarm preferably sounds continuously during a first time period and intermittently thereafter.
