摘要:
An external battery pack for protecting against a battery fire or battery explosion, said battery pack connectable to an emergency locator transmitter (ELT) typically mounted in an aircraft. The external replaceable battery pack has a protective metal enclosure and a removable metal cover. The box includes an aluminum honeycomb grid core mesh with passages, each sized to receive a single battery and a pair of printed circuit boards on top and bottom to receive battery power, voltage and current, from multiple batteries for use with an ELT. By using smaller and more batteries together, the possibility of a catastrophic failure is greatly eliminated or reduced in that a smaller battery have a lesser fire or explosion potential. The batteries are isolated from each other from excessive heat or destruction by explosion.

A protective metal enclosure box for lithium batteries that includes batteries subject to fire and explosion comprising a rigid metal covered box that includes an aluminum honeycomb grid core mesh that can receive multiple individual batteries spaced apart from each other and protected from each other thermally and from explosion. The protective battery pack box includes a pair of printed circuit boards for interacting with the batteries for transmitting voltage and amperage outside of said battery pack.

An emergency position indicating radio beacon that includes a waterproof rigid housing, antenna, a retention carriage strap securely mounted around its exterior periphery on a spool in a storage position. In an emergency the user can unwind the retention carriage strap and form an adjustable loop in the strap using hook and loop fasteners to firmly attach the strap connected to the EPIRB housing to the user's arm that allows a user to transport the radio beacon with the retention carriage strap in a hands-free configuration.

摘要:
A communication device (10) in a clam shaped housing includes a camera (12) incorporated within a first portion (18) of the clam-shaped housing and a lens (14) incorporated within a second portion (19) of the clam-shaped housing. The camera and the lens can substantially align when the first portion pivots relative to the second portion. The lens can be an afocal converter lens that changes an effective focal length of a lens of the camera from among a wide angle, a telephoto, and a macro lens. The communication device can have at least one among a main display (15) on a flip portion of the communication device or an auxiliary display (16) on an opposing side (21) to enable viewing without the lens when the communication device is an open position and the auxiliary display can enable viewing with the lens when the communication device is in a closed position.
