Abstract: A detector for detecting the removal and/or insertion of a weapon out of and/or into a holster. The detector may transmit a message each time the weapon is removed from the holster. A recording system may receive the message and determine whether or not it will begin recording the data it captures. A detector may detect the change in a magnitude of an inductance and/or an impedance of a circuit to detect insertion and removal of the weapon into and out of the holster. The holster is configured to couple to the detector to position the detector to detect insertion and removal of the weapon. An adhesive tape may couple a detector to a holster.

Abstract: A system and method for improving an actual installed rotation of a prosthesis, particularly prostheses having a preferred rotation with respect to a frame of reference of a patient.

Abstract: A method and system to use compressed fluids to generate electrical energy or an equivalent useful form of energy. A first embodiment uses pressurized air that can be stored to selectively and directly generate energy as required. A second embodiment uses a pressurized working fluid that can be stored to selectively and directly generate energy as required. A third embodiment uses at least one compressible floor module to compress at least one working fluid that can be stored to selectively and directly generate energy as required. The working fluid in various embodiments of the invention can be air, steam, oxygen, hydrogen, nitrogen, commercially available Freons, carbon dioxide, methane, ethane, propane, butane, various types of natural gas, ammonia, an equivalent type of gas, or an appropriate liquid.
