Abstract: Latching components of a padlock are driven by a motor (48) between latched and released position. An encoder element (80) with associated optical elements (88, 90) provides position information to a control circuit. The control circuit correlates the position information with the signal directing power to the motor (48) so that the motor (48) is precisely controlled for moving the latching elements between release and latch. If the motor jams (sensed by overcurrent), it is operated briefly in alternating directions to try and dislodge the grit or ice causing the jam. The padlock shackle (24) is latched into place by balls (94) which are driven in recesses in the shackle legs (24). The use of plural balls (94) on at least one side helps isolate the drive motor (48) and gears (42) from grit that may enter through the padlock's top shackle holes.

Abstract: A fire detection system (100) combines a CO2 gas detector (14) with a smoke detector (2). Logic circuitry (400) 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 (810) 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 (222, 233) disables a local air conditioning system thereby helping to isolate and control any existing fire.

Abstract: A wireless alarm system (10) employs two-way transceivers (32, 60) in a network of smoke detectors (16), a base station (12), and other sensors. A keypad (14) is not needed because the system is reset by pressing a Test/Silence button (66) built into every detector or sensor. A siren is also eliminated because a sounder (64) in every detector sounds an alarm when any sensor is triggered. This is possible because every detector includes a transceiver that can receive alarm messages from any other detector. AC power wiring is also eliminated because the base station and sensors are battery powered. Only a telephone connection (48) is needed if the system is to be monitored. In apartments or dormitory installations, smoke detectors in one apartment relay alarm messages to the next apartment, and onto the next, and so on, to a centralized base station for the entire facility. The centralized base station can be located in an apartment manager's office for immediate notification of an alarm, improper smoke detector operation, low or missing battery indications, and dirty smoke detector indications. The two-way wireless alarm system can save many lives in apartments, where smoke detectors batteries are often depleted or removed.

Abstract: Security systems (10) are provided in which a plurality of different lock devices (19, 21, 20, 22) are all responsive to a single key (12). Outdoor lock devices (19, 21, 20, 22) which may not be used for a period of years are unlocked by the key (12) in cooperation with a manually-applied unlocking force (74). A key nest (22) is provided which can controllably apply an unlocking signal to any electronically-controlled device.
