Title: Anti-theft apparatus and method for altering the display output of a stolen electronic device
Inventor: MCCARTHY SHAUN
IPC: G06F21/84
Filed: 1996-02-23
Abstract: This application describes a means for inhibiting the theft of an electronic device. The electronic device generally comprises a processor unit and a display device for displaying operational output from the processor unit, and the invention resides in including within the electronic device a receiver unit adapted to receive remotely transmitted signals and capable of causing the processor unit to at least partially obscure or change the output on the display device after such a signal has been received. The electronic device can be any device that produces a visible output. In preferred forms of the invention, the obscuring of the display output is by overprinting a message informing you that the device is stolen, and more preferred versions include a unique identification code in that message. This enables the authorities to identify the true owner of the article. The receiver unit can be the receiver of a radio pager, for example. Thus, on noticing the theft of the device the owner alerts a service provider who activates the receiver unit.

Title: Latch and release perforating gun connector
Inventor: HENKE JOSEPH A
IPC: E21B43/116
Filed: 1997-08-08
Abstract: A perforating gun connector is provided for downhole use in oil and gas fields.  The perforating gun connector includes a stinger and a stinger receptacle.  The stinger is adapted to be stabbed into the stinger receptacle.   A loaded engaging member movable between a running position before the stinger is stabbed into the stinger receptacle and a latched position when the stinger is stabbed into the stinger receptacle to latch the stinger and the stinger receptacle together.   A release member retains the loaded engaging member in the running position.  When the stinger is stabbed into the stinger receptacle and a set force is applied to the stinger and stinger receptacle, the release member releases the loaded engaging member to move to the latched position and latch the stinger and the stinger receptacle together.  According to a second aspect of the invention, the perforating gun connector is releasable, further including a releasable stop member to stop the engaging member in the latched position.   When the stop member is released, the engaging member moves to a released position such that the stinger and stinger receptacle are separable.   According to a third aspect of the invention, a  perforating  gun  connector  is  provided  with  an  internal explosive  transfer  system  for  transferring  the  detonation signal from one perforating gun,  through the perforating gun connector, and to the next perforating gun.  In addition, a method of connecting a first perforating gun section to a second perforating gun section is provided.
