Abstract: Compression screw systems for stabilizing and/or compressing bones of the extremities, characterized by a compression screw component and a hook component. The hook component is received on the compression screw component in any rotational position relative to the compression screw component in order to orient the hook component relative to a bone or bones requiring stabilization and/or compression. The hook component includes an anti-rotation feature, while a configured flange thereof provides a hook that extends about and overhangs a part of the bone. The compression screw component and the hook component may include cooperating structures that allow the hook component to attach to the compression screw component or allow the compression screw component to self-orientate with respect to the hook component upon compressing engagement of the compression screw head with the hook component. The configured flange of the hook component may terminate with a single, double or multiple tined prong.

Abstract: A safety mechanism for a firearm consisting of a specialized scanning mechanism built into the firearm's trigger. The scanner is programmed to read the unique fingerprints of a given individual. The device is also capable of holding the programmed print information for more than one person, so that multiple people would he able to use the firearm. However, usage is limited to only those persons whose hand prints have been prestored in the scanner. The scanner mechanism is connected to the firearm's safety lock. The safety is prevented from being released without proper authorization from the scanner. When a person grips the weapon and places his finger on the trigger, the pressure of the finger on the trigger activates the scanner, and the scanner reads the fingerprint to determine if the scanned fingerprint matches one of the pre-stored fingerprint images. If the individual is an authorized user, the scanner transmits a signal to the safety, releasing this device and activating the firearm for use.
