Abstract: Actuation of the firing mechanism of a firearm is prevented until grip pattern sensing means on the handgrip of the firearm supply to a microprocessor signals corresponding to a grip pattern stored in a programmed simulated neural network memory. All of these components are contained within the firearm. Programming of the neural network memory is accomplished by using a host computer with a simulated neural network to train that network to recognize a particular grip pattern using grip pattern signals generated by the grip pattern sensing means as the sensing means is repeatedly gripped for the person for whom the firearm is to be programmed.

Abstract: An economical method for converting video images into binary form and then storing the binary representations onto disks designed for binary data. A single image will fit onto a single track of the disk. A new method of modulating analog video signals and converting them to binary signals is disclosed. The converted images are then stored in binary form on disks designed for personal computers. A directory of stored images can be maintained on a separate disk under the control of a personal computer. The disk for storing the video images is under the control of a microprocessor.
