An electronic device designed to activate a municipal mechanical fire siren upon the receipt of fire from any one of a plurality of inputs, where said fire siren is used to alert fire personnel of an emergency. In addition, through the use of a built in 24 hour clock, the device can operate the siren at noon each day, as a means of automatic testing. The gain time of the siren cycle and the number of cycles per alarm can be preset by the user.

The invention concerns a method and an apparatus for time-staggered generation of identifying signals by programmable automation components (AK1, AK2) with a system time recorder (SZ). A user (A) or an automation component (AK1, AK2) or a user program (AP) can register a time-staggered identifying signal (K) with an event manager (EV). The event manager (EV) controls a system time counter (SZ) and signals waiting events (E1-E3) back to the user (A) or the automation component (AK1, AK2) or the u...

A timed switching circuit includes timer means for timing an event, timer means for timing the length of an alarm signal, and timer means for timing delays prior to and immediately after an event is timed. The circuit also includes an appliance control/indicator means for controlling an appliance in response to a timed event and indicating the operational state thereof.

A protective alarm system for a vehicle or the like wherein a protective switch initiates operation of a circuit combining two timing effects : effecting time delaying of an alarm device, and determining the duration of the alarm. Once initiated by the protective switch, the alarm is actuated after a predetermined delay and for a predetermined duration despite any action on the switch such as a periodical opening and closing. Circuitry operated by a key switch defeats instantaneously actuation o...

Apparatus is disclosed for controlling and monitoring the operation of load means that cyclically operate a load device, such as the dosage supply means of a clinical analyzing system. The load means includes a load motor the operation of which is initiated by an actuating switch that is operated by synchronously-driven program means to initially energize the load motor, whereupon a self-latching holding switch is operated from a first condition to a second condition to maintain the load motor e...

A system for controlling the operation of an appliance of the type having a plurality of machine functions to be activated and deactivated in accordance with a control strategy includes a plurality of selectable cycles each made up of a series of events and an array of user actuatable membrane switching devices for selecting at least one cycle of operation for the appliance. The array of membrane switching devices also allow the user to program an optional event within the selected cycle and to ...

An electronic control system, as for instance a microcomputer in a microwave oven, is automatically reset when a signal, normally provided by the microcomputer within some normal interval relative to some reference, fails to occur. A reset command signal is generated and resets the microcomputer to some initial point from which normal operation may begin or resume and at which certain output loads may be rendered inoperative. A display device associated with the appliance is repetitively scanned...

Disclosed is an apparatus for realizing an alarm function using a mobile terminal and a charging device for charging the mobile terminal. The mobile terminal includes a controller for generating an alarm control signal a predetermined time period ahead of a predetermined alarm time, and a first interface for transmitting the alarm control signal to the charging device. The charging device includes a second interface for receiving the alarm control signal from the mobile terminal, and a lamp driv...

A welt seaming lace assembly, for forming welted seams for upholstered furniture, formed of a thin, flexible, thermoplastic core covered with an open braided mesh formed of thread, and a heat reactable adhesive coating the thread and core, and a thin, thermoplastic, outer covering, including an integral sewing flange, hot extruded around the adhesive coated mesh covered core. The adhesive coating is applied hot to momentarily soften the core for both adhesively bonding to and partially embedding...

When a switch for manually terminating an informing operation of a call informing device is not depressed during an informing operation, the informing operation is automatically halted after a first set time of a first timer. After a second period of time T, determined by a second timer, elapses from the start of the informing operation, the informing operation is repeated for the first set time of the first timer. After the second period of time T elapses from the start of the second informing ...
