    Abstract: A fire detection system combines a CO2 gas detector with a smoke detector. Logic circuitry combines the outputs of both detectors to minimize false alarms and provide a rapid response time. In a preferred embodiment the need for periodic cleaning is reduced. In a further preferred embodiment, two alarms indicative of two different types of fires, for example flaming fires and nonflaming fires are available. A map of flaming fire and smoke may be assembled by the system to guide the firefighters. In a yet another preferred embodiment, a tentative fire alarm indication disables a local air conditioning system thereby helping to isolate and control any existing fire.

    Abstract: The latching components of the padlock are driven by a motor between positions for latching and releasing the padlock shackle. Power for the motor is provided by a source carried in an electronic key. An encoder element with associated optical elements provides position information to the control circuit carried inside of the padlock. The control circuit correlates the position information with the signal directing power to the motor so that the motor is precisely controlled for moving the latching elements between release and latch.

    Abstract: Various enhancements are provided to a pushbutton lock to enhance its security. One is the provision of button tips that are mounted on the ends o f the button assemblies and spring-loaded to protrude from the face of the loc k, regardless of whether the underlying button is "in" or "out". By this arrangement, a bystander cannot readily see the button combination by the pattern of depressed buttons. This arrangement also reduces tactile feedback between the underlying button assembly and the externally available button tips, increasing resistance to pick attacks. A further enhancement is the provision of button bars between adjacent pairs of button tips. Whenever any of the button tips is manually depressed, the corresponding button bar is pressed into engagement with, and prevents movement of, a member that must b e moved in order to unlock the lock. This arrangement further increases lock security by preventing an attacker from experimentally pressing buttons and judging the tactile effect thereon in attempted unlockings of the lock.
