Abstract

A microprocessor based device for monitoring a location and recording the time and date of each event involving the presence of an object such as a deer at the monitored location. A transmitter of an infrared beam may be mounted on a tree on one side of a trail in alignment with an infrared receiver mounted on a tree on the opposite side of the trail. When an object breaks the beam, the time and date of the event are recorded in memory, and the time and date of each event may be retrieved from memory and displayed in chronological order on an LCD display on the face panel of the receiver. Alternatively, a portable printer may be used to obtain a printed record of recorded events. Optionally, a camera may be aimed at the monitored location and automatically activated to photograph the animals present at the monitored location. The electronics incorporates various power conserving features to provide long life for the batteries so that extended operation is possible in remote areas.

Claims

1. Apparatus for recording the movement of large game animals past a preselected location, said apparatus comprising:

means for directionally transmitting infrared energy in a path intersecting said preselected location and in a series of discrete bursts each including a selected number of infrared pulses and each being transmitted at a selected time following the immediately preceding burst;

infrared sensitive receiving means adapted for placement along said path to detect the bursts of infrared energy that are transmitted past said preselected location;

means associated with said receiving means for providing an electrical signal indicative of the presence of an animal at said preselected location whenever a predetermined number of bursts in succession are not detected by said receiving means;

means for storing data representative of the time and date of each signal provided by said signal providing means; and

means for retrieving said data.

2. Apparatus as set forth in claim 1, including means for varying said predetermined number of bursts.

3. Apparatus as set forth in claim 1, including means for varying the number of pulses in each burst.

4. Apparatus as set forth in claim 1, including means for varying the time between each burst and the next succeeding burst.

5. Apparatus as set forth in claim 1, wherein said data retrieving means comprises means for displaying the time and date of each signal in chronological order.

6. Apparatus as set forth in claim 1, wherein said data retrieving means includes means for printing a printed record of the time and date of each signal with the times and dates arranged in the chronological order of the signals.

7. Apparatus as set forth in claim 1, including:

a camera adapted to be focused on said preselected location; and

means for activating said camera to photograph said preselected location in response to generation of a signal by said signal generating means.

8. Apparatus as set forth in claim 7, including means for disabling said camera to prevent it from photographing during selected times and enabling the camera to permit it to photograph during other selected times.

9. Apparatus as set forth in claim 4, wherien said receiving means includes means for detecting the time between successive bursts and automatically adjusting to a new time between bursts when the time between bursts is varied.
