Abstract: An infrared imaging composition contains two essential components, namely an infrared absorbing compound, and a phenolic resin that is either mixed or reacted with an o-diazonaphthoquinone derivative. These compositions are useful in photosensitive elements such as lithographic printing plates that can be adapted to direct-to-plate imaging procedures.

Abstract: A system having a computer, test control logic, an electrostatic discharge unit and a high voltage probe unit is provided for performing multiple, random, asynchronous electrostatic discharge testing of machines. The test control logic includes multiple, asynchronous, random, firing logic for controlling the states of a plurality of output lines which send control signals from the computer to the electrostatic discharge unit and the high voltage probe unit. The test control logic allows a user a preference of testing modes through an interactive input graph. The user may specify either a run time experiment or a specific probability of test coverage test.

Abstract: A portable personal security device of compact size capable of being carried in a pocket or purse or the like, has a pistol-like configuration with a handgrip portion and a barrel portion. The device includes a noxious chemical which may be discharged to fend off an attack by an assailant, and an audible alarm which may be sounded to attract attention and/or to discourage an attacker. Further, a light is provided on the device so that it can be used as a flashlight. A plurality of finger-receiving openings are formed in the handgrip portion to effect a secure grip on the device and make it difficult to dislodge from the hand of the user. These openings also assist in quickly and properly orienting the device. An actuator for energizing the light, the chemical discharge and the audible alarm includes structure which enables sequential activation of these devices.

Abstract: A modular, interactive gaming system which may be reconfigured to play a variety of participatory games. The system includes a plurality of interconnectable modules which may be combined to define passageways and gaming rooms in a variety of living game board configurations. Sensors and sensory signal generators are disposed in the passageways and gaming rooms which are in communication via a cable network with a control computer which directs the play of the game in accord with a program resident therein. The combination of modular units and a programmable computer permits great flexibility in game design and play.

Abstract: An amusement system for use by one or more participants includes weapons which may be carried, aimed and triggered by the participants to fire objects, such as paint balls, or electromagnetic energy, such as laser light. The participants wear sensors which generate signals upon participant being "hit" by an emission. The system includes a structure having a series of elongated passageways. Each passageway is divided by a central wall into a pair of trackways which lead from common entrance area at one end to a gaming area at the opposite end. Viewing areas in which the activities of the participants in the gaming area may be observed are disposed adjacent to the gaming area. Sensors are disposed along the passageways and in the gaming areas to detect the positions and activities of the participants to provide the signals to a central computer.
