Alarm clock
First Claim
1. An alarm clock connectible to electrical A.C. power lines, the alarm clock comprising:
- a housing;
display means, mounted in the housing, for displaying time of day and preset alarm time information;
clock means, mounted in the housing, for generating and supplying time of day information to the display means, and for generating an alarm signal when the time of day corresponds to a preset alarm time;
means, mounted on the housing and input to the clock means, for setting time of day and alarm time information and for de-energizing the alarm signal;
a first electrical outlet, mounted in the housing, for supplying electrical power to a first external electrically operated device electrically connectible to the first outlet;
receiver means, mounted in the housing, for receiving and detecting power line carrier signals transmitted on the electrical A.C. power lines to the alarm clock from a to more device in response to the occurrence of an input stimuli detected by the remote device; and
means, responsive to the clock means and the receiver means, for applying electrical power to the first outlet at one alternatingly on and off frequency in response to the generation of the alarm signal and at another distinct on and off sequence in response to the detection of the power line carrier signals by the receiver means.

Abstract
An alarm clock controls the supply of electrical power to a first outlet mounted on the clock housing and receiving a plug-in external electrical device to periodically change the state of the electrical device in response to an alarm time signal. A second controllable outlet is also mounted on the housing for receiving a second plug-in external electrical device. Selectible steady or pulse power is provided to the second outlet. A receiver detects power line carrier signals on the incoming electrical power lines generated by a remote device in response to the occurrence of a sound producing event or other signal. The receiver causes the clock to supply power to either or both outlets depending on the position of a function switch in response to a detected power line carrier signal. An audible sound generator provides an audible alarm tone in response to an alarm signal. Frequency and volume controls selectively vary the frequency and volume of the audible alarm tone. A test button activates the outlets and audible sound generators to test proper operation and desired settings of the alarm clock.
