Abstract: A bullet jacket, and method of making a bullet jacket are disclosed, wherein bullets placed therein will, when fired, expand at low velocities, while maintaining high weight retention at higher velocities. The bullet jacket is preferably made of a copper based material, and comprises a solid base portion and an upper end portion defining a cavity therein, in which a bullet core material is located. The walls of the cavity decrease in width away from the base and curve inwardly to form an ogive shape. The length of the cavity section of the bullet jacket is between 58 to 61 percent of the total length of the bullet jacket, and the total weight of the solid base portion of the bullet jacket is between 48 to 52 percent of the total weight of the bullet jacket. The bullet core is made by using conventional means to seat and enclose the bullet core within the bullet jacket of the present invention. In manufacturing the bullet jacket, the jacket mouth or lip thickness is made to be between .025 to .060 of an inch. Four to 6 cuts are used to cut the jacket lip to a minimum depth of .015 inch to a maximum depth of .450 inch.

Title: Personal activity sensor and locator device
Inventor: WEGNER JUERGEN WERNER
IPC: A62B33/00
Filed: 2005-08-08
Granted: 2009-02-24
Abstract: A rescue device has a motion detector and a transceiver that operates either to transmit a locating signal, which can be tracked by others, or to receive and track a locating signal transmitted by another. A control logic circuit suppresses transmission of the locating signal by the transceiver unless a motion signal, generated by the motion detector responsive to the user's movement, indicates that the user has not moved for a predetermined time interval. Thus, the rescue device can transmit the locating signal when the user is motionless, providing notice that the user is immobile and aiding others in locating the user. When the receiver is operating, it guides the user in locating the source of a transmitted locating signal to aid the user in locating an immobilized person or a building exit. An override can be provided to allow transmission of the locating signal regardless of movement.
