Abstract: A training aid is a figure that has an inflatable three-dimensional headless body, an inflatable three-dimensional head, and a way to removably attach the head to the top of the body. The body has a torso, legs terminating in feet, and arms. The feet may be filled with a liquid or a solid particulate material such as water or sand, which is the sole support for the figure.

Abstract: A security system has a wall mounted assembly for installation adjacent an entry door and includes a motion detector for sensing intruders, an alarm for sounding a warning, an alarm circuit, a radio receiver responsive to two codes, and an electric door striker. A portable miniature transmitter has two transmission codes to activate the receiver, one for toggling the alarm circuit between armed and disarmed condition and for releasing the door upon disarming the alarm circuit. When the circuit is armed the motion detector is able to activate the alarm. The second transmission code activates the alarm if the circuit is armed. Remote self contained motion detector and transmitter units for use in other rooms use the second code to activate the alarm when motion is detected by those units.
