The apparatus senses the absolute elevation and azimuth of a device, such as a gun in an arcade target shooting game. The gun is fixed to a shaft which is pivotable about horizontal and vertical axes and which is connected by two linkage assemblies, respectively, to two rotatably mounted encoder plates for rotating them, respectively, in response to pivoting of the gun about the two axes. Each plate has a plurality of apertures arranged in seven concentric rings in accordance with the Gray code, the arcs respectively intercepting seven light beams which are directed to seven photodetectors. At different rotational positions of the plate, different ones of the detectors will sense light. The apertures are arranged to produce discrete coded indications of each one-degree increment of movement of the gun over a range of about 90.degree..

An adapter includes a program-controlled microprocessor provided with input means adapted to be coupled to the output of a trackball-type position control device, output terminals and selection means for selectively conditioning the processor for operation in either of two modes. In one mode the adapter converts the trackball output signals to a form which can be inputed to a port adapted for use with a switch-type joystick and yet includes both speed and direction information. In the other mode the adapter converts the trackball output signals to a form which can be inputed to a port adapted for use with a trackball device. A ladder network is connected to the adapter output terminals in its second mode for converting the output signals to a form which can be inputed to a port adapted for use with a proportional type joystick.

Pick-up means convert mechanical vibrations into an electrical signal at a corresponding frequency. The pick-up means is attached to a portion of the vehicle, which is mechanically coupled to the hubcap or wheel cover. A circuit responds to the electrical signal to provide an operating signal to generate an alarm.

An electronic door lock has a lockbolt operable between locked and unlocked positions by an electrically energizable bolt mover which is responsive to an electronic locking circuit and an electronic unlocking circuit. A switch actuates the electronic unlocking when the door is to be opened. A control circuit, also responsive to the switch, generates a control signal which is time-delayed by at least a predetermined interval after the actuation of the unlocking circuit. The locking circuit responds to the control signal by energizing the bolt mover so as to move the lockbolt to the locked position, thereby causing the door to be automatically locked after at least the predetermined interval following the unlocking of the door.
