Event occurrence time and frequency detection and recording apparatus
First Claim
1. An apparatus for detecting and recording the time and frequency of the presence of an animal at a surveillance site comprising:
- a weatherproof housing;
an electric power source mounted in the housing for supplying electric power to the apparatus;
a central processing means mounted in the housing and operating a control program;
infrared sensor means, mounted in the housing and having a field of view in the form of a planar pie-shaped sector extending radially outward from the housing and input to the central processing means, for sensing the presence of an animal at the surveillance site within the entire field of view of the sensor means;
memory means, mounted in the housing and coupled to the central processing means, for data and control program storage;
a clock mounted in the housing and coupled to the central processing means, the clock providing continuous clock pulses;
display means, mounted in the housing and coupled to the central processing means, for displaying the date, time and number of separate presences of an animal sensed by the sensor means in a predetermined time period; and
the central processing means being responsive to the control program and to the input of start date and start time data from the input means for storing the start date and start time data in the memory means, and responsive to the presence of an animal sensed by the sensor means to store in the memory means the data and time of the detected presence of an animal and responsive to the input means for recalling from the memory means and sucessively outputting to the display means for visual display the data and time of the detected presence of an animal at the surveillance site;
wherein said central processing means establishes sucessive time periods, each having a predetermined time interval, starting from the initial start date and start time of detecting and recording and said central processing means includes means responsive only the presence of an animal sensed by the sensor means for storing in the memory means the date and start time of only the time period in which at least one animal was detected.

Abstract
An apparatus for detecting and recording the time and frequency of occurrence of events at a predetermined surveillance site includes a sensor providing successive output signals corresponding to successive detections of an event occurrence at the surveillance site. The output signals from the sensor are input to a central processing unit operating a control program stored in a memory which stores in the memory the date, time and number of occurrences of events at the surveillance site. The apparatus also includes a keyboard for inputting start date and start time information and for initiating the operation of sensing of events and the recall of stored date, time and event occurrence number information for display on a digital display mounted on the apparatus. All of the operative components of the apparatus are powered by a d.c. electric power source and are contained in a waterproof housing mountable at a predetermined surveillance site.
