Abstract: A clock alarm deactivation system for a clock with an alarm switch for turning on an alarm device at a preset time. The alarm device can be deactivated by manually operating in sequence a series of pushbutton switches. Each pushbutton switch in the sequence is randomly selected and is identified by an individual indicator light. When setting the clock alarm, the user adjusts a selector control that will select the number of pushbutton switches that the user will be required to push in sequence in order to totally deactivate the alarm device. When the clock alarm sounds at the preset time, simultaneously the first pushbutton switch randomly selected is activated and its identifying indicator light is turned on. After the user pushes the first-activated pushbutton switch the alarm is temporarily silenced and the device will randomly select the second pushbutton switch in the sequence and turn on its respective indicator light.

Abstract: An alarm clock with an alarm system which can be deactivated by means of either a local or remote manually operated push button switch which must be held in a depressed condition for a predetermined period of time in order to effectively deactivate the clock alarm. Means is provided to adjust the length of required switch hold-down time. An indicator is provided for showing the completion of the required hold-down period. In the case of remote deactivation, wherein the user must walk to the location of the push button switch, a radio link is employed to couple the remotely located switch with the locally positioned clock alarm system and to provide the desired alarm deactivation. The completion of the hold down period is signalled either by visual indicating means or by audible sounding means.

Abstract: An alarm clock with a local alarm system including a movement-operated switch, a relay with normally closed contacts, and an audible alarm device connected to the power lines through the movement-operated switch and said relay contacts. Said relay is energized by a circuit including a switch closed by lifting an operating knob, or in an alternative form, by lifting the entire clock. The system includes time delay relay latching means to prevent immediately latching the alarm circuit open but requiring the user to maintain the lifting force for a predetermined delay period, sufficient to produce wakefulness of the user, after which the alarm circuit is latched open. A signal lamp shows the delay period to be in effect until the delay period has been completed, thereby requiring the user to manually maintain the lifting force until the lamp becomes extinguished.

Abstract: An alarm clock with a local alarm system including a movement-operated switch, a normally-closed key-operated switch and an audible alarm device connected in series across the power lines. The switch-operating key may be remotely located so as to require the user to leave his bed in order to obtain the key, insert it in the key-operated switch, and turn the key so as to shut off the alarm. The system may include a time delay latching arrangement to prevent immediate latching the key switch open and to require the user to hold the key turned for a predetermined delay period, sufficient to produce wakefulness of the user. A signal lamp shows the delay period to be in effect until the period has been completed, thereby requiring the user to manually hold the key-operated switch open until the lamp becomes extinguished.

Abstract: An alarm clock system consisting of a clock with a local alarm circuit and provided with a remotely located turn-off control device actuated by a push button switch. The local alarm system, in response to an electrical signal produced by the clock at a preset time, generates a first sound in the form of a continuous tone lasting for 40 seconds, followed by a strident pulsating sound for another 40 seconds. To turn off the alarm, the user must get out of bed, walk to the remote location, and then depress the switch push button and hold it for a predetermined time, such as 12 seconds. Actuation of the push button switch causes the remote control component to generate and transmit a radio signal, which is detected by a radio receiver in the alarm clock local component. Also, an indicating lamp on the remote component is energized and goes off after 12 seconds of continuous depression of the push button.
