activity timer means for receiving therein either a first count or a second count;
analyzing means arranged to analyze the activity and sensor identification data in signals received by the processing means from the first and second sensor means to determine the origin of the signals and the particular monitored activities, said analyzing means being operative for each signal identifying the first sensor means and specifying the occurrence of the first associated activity to cause a first count to be placed in the activity timer means, and operative for each signal identifying the first sensor means and specifying the occurrence of the second associated activity or for each signal identifying the second sensor means to cause a second count to be placed in the activity timer means; and
means operative if after a first count has been caused to be placed in the activity timer means as a result of the occurrence of the first activity monitored by the first sensor means and before the occurrence of the second activity monitored by the first sensor means the second sensor means monitors the occurrence of its associated activity and produces a corresponding signal to prevent a second count from being placed in the activity timer means to replace the first count caused to be placed therein as a result of the occurrence of the first activity monitored by the first sensor means.

Abstract
Apparatus for a monitoring and signalling system such as a home health car system includes a first sensor operative to monitor the entry and exit of an individual from a room (such as a bathroom), and other sensors operative to monitor usage of appliances such as lamps, televisions, refrigerators and telephones. Each sensor, upon monitoring an associated activity, produces and applies a signal to a microprocessor and causes an activity timer in the microprocessor to be set to either a first time period of about 1-2 hours (for an entry into the room) or a second time period of about 8-10 hours (for an exit from the room or for use of an appliance). The activity timer cycles through its associated time period and initiates an alarm sequence at the expiration of the time period for indicating a lack of activity. Thus, if an individual who has entered the room does not exit within the 1-2 hour period, or an appliance is not used for a period of 8-10 hours, an alarm sequence is initiated. In accordance with the present invention, the microprocessor operates to examine signals from the sensors and once the activity timer has been set to the 1-2 hour period by virtue of a first individual entering the room to prevent the timer from being set to the 8-10 hour period by virtue of use of an appliance by another individual while the first individual is in the room.
