Device and method for alerting hunters
First Claim
1. A safety device adapted to be carried by a hunter when hunting game to detect the presence of other hunters carrying like devices and to alert the other hunters of the presence of the hunter within a predetermined range, said device comprising:
- transmitter means for transmitting a signal to be received by like devices carried by the other hunters, said transmitter means including means for modulating the transmitted signal to encode the transmitted signal with identification data;
receiver means for detecting signals transmitted from like devices carried by the other hunters while the other hunters are within the predetermined range, including means for decoding encoded signals; and
indicator means responsive to the detection of the signal transmitted from like devices for warning the hunter of the presence of the other hunters within the predetermined range, said indicator means being adapted to warm the hunter in a manner that is imperceptible to the hunted game.

Abstract
A hunter alert device (9) for use by hunters when hunting wild game consists of transmitter means (21), receiver means (22), an antenna (11), a transceiver controller (20), and an indicator means (12). The device (9) operates by intermittently transmitting a modulated radio frequency signal through antenna (11) and listening for radio frequency signals transmitting from alert devices worn by other hunters. When a signal is detected, the receiver means (22) determines whether the signal is within a predetermined range of the hunter and, if so, activates the indicator means (12) to warn the hunter.

14. A hunter safety system for use by hunters when hunting game to detect the presence of other hunters within a predetermined range and to alert the other hunters of a hunter'"'"'s presence within the predetermine range, said system comprising:
-
a hunter alert device to be carried by each hunter while hunting game in an area potentially having other hunters, each of said hunter alert devices including; transmitter means for sending a radio signal encoded with identification data for identifying a hunter in an omni-directional pattern to be received by like hunter alert devices carried by the other hunters; receiver means for detecting the radio signal sent by like hunter alert devices carried by the other hunters while the other hunters are within the predetermined range; and indicator means responsive to the detection of the radio signal by the receiver means for warning the hunter of the presence of the other hunter within the predetermined range, said indicator means adapted tow arm the hunter in a manner imperceptible to the hunted game.

15. A method for detecting the presence of hunters within a predetermined range of each other while the hunters hunt for game, said method comprising the steps of:
-
transmitting an electromagnetic signal from each hunter in an omni-directional pattern to be received by the other hunters; receiving the transmitted electromagnetic signals from the other hunters while the other hunters are within the predetermined range; pulse modulating the electromagnetic signal to encode identification data for identifying a hunter associated with the electromagnetic signal; and indicating to each hunter upon reception of the electromagnetic signal that another hunter is within the predetermined range, said indicating step adapted to be performed in a manner that is imperceptible to the hunted game.
