Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is a Continuation of U.S. patent application Ser. No. 16/198,508, filed 21 Nov. 2018, entitled “ARCHERY PROJECTILE LOCATION FACILITY,” which claims the benefit of U.S. Provisional Application No. 62/621,089, filed 24 Jan. 2018, which are hereby incorporated by reference in their entirety.

FIELD OF THE PRESENT DISCLOSURE

The present disclosure generally relates to archery projectiles. More particularly, the present disclosure relates to locating archery projectiles after a flight has been initiated.

BACKGROUND OF THE PRESENT DISCLOSURE

Many archery projectiles are lost after flight and are not recovered. For example, archery projectiles that miss an intended target may be lost in forests, shrubs, and/or grass.
Many game animals are targeted by hunters using archery projectiles. Many of these game animals are injured after being impacted by an archery projectile. However, some of the injured game animals may not be recovered by the hunters. Many existing archery projectile tracking systems may not be adaptable to assist in the tracking of an injured animal when the projectile completely passes through the animal or is damaged from animal movement.
Many existing disclosures on archery projectile tracking systems are based on the intended use of the Global Positioning System (GPS) for location. However, many GPS receivers are too large to be inserted into a hollow arrow shaft. In addition, a transmitter co-located with a GPS receiver may not be able to establish a connection with a remote receiver to transfer GPS based location information when signal transmissions are blocked by terrain and/or dense vegetation. Many existing archery projectile tracking systems are configured to emit radio signals. However, radio signals emitted at a single power level may limit the effective range of a directional receiver. For example, an emitter transmitting a high-powered signal may overload the front end of the directional receiver preventing the determination of a direction of the emitter when the distance to the emitter is a short distance. For example, an emitter transmitting a low-powered signal may not be detected by the front end of the direction receiver preventing the determination of a direction of the emitter when the distance to the emitter is a long distance. Many existing archery projectile tracking systems are configured to emit analog signals. Transmission of multiple analog signals in a single hunting zone may cause confusion to the users of one or more receivers.
Many existing archery projectile tracking systems may not be adapted easily to a plurality of third-party arrow shafts and/or a plurality of third-party broadheads. Employment of many existing archery projectile tracking systems may negatively impact the trajectory and/or the kinetic energy of archery projectiles during flight, especially over ranges required in many hunting situations. Employment of many existing archery projectile tracking systems may negatively impact the penetration depth into a target game animal.
What is needed is an improved archery projectile location facility.

The signal code field 278 may comprise a signal code. The signal code may be received in the data frame (e.g. 1400) transmitted from the elongated body (e.g. 20).

According to an embodiment, a directional receiver (e.g. 30) may be adapted to communicate information to one or more remote computing devices (e.g. 36). The information may be communicated through employment of at least one data frame (e.g. 2000). For example, a first data frame may comprise the following data:

- 001 BL063 PW045 IX1 M0 TA+28.0 ID0093006A400F44554E45
  The first field (001) may represent frame information (e.g. 210). “001” may, for example, indicate good frame integrity. The second field (BL063) may represent energy status information (e.g. 276). “BL063” may, for example, indicate 63 percent remaining battery life. The third field (PW045) may represent power information (e.g. 220). “PW045” may, for example, indicate a power level measured by the directional receiver (e.g. 30). The fourth field (IX1) may represent a signal code. “IX1” may, for example, indicate a first signal code. The fifth field (M0) may represent movement information. “M0” may, for example, indicate zero movement at an elongated body (e.g. 20). The sixth field (TA+28.0) may represent temperature information. “TA+28.0” may, for example, indicate a temperature of 28 degrees Celsius at the elongated body (e.g. 20). The seventh field (ID0093006A400F44554E45) may represent a signal ID. “ID0093006A400F44554E45” may, for example, indicate a signal designator. For example, a second data frame may comprise the following data:
- 001 BL063 PW026 IX2 M0 TA+28.0 ID0093006A400F44554E45
  In this example, only the third field (PW026) and the fourth field (IX2) differ from the first data frame. In the second data frame, “PW026” may, for example, indicate a lower power level than the “PW045” from the first data frame. In the second data frame, “IX2” may, for example, indicate a second signal code. Therefore, the data from the first data frame and the data from the second data frame may indicate that the first signal code was transmitted at a higher power level from the elongated body (e.g. 20) than the second signal code. Although these examples illustrate two data frames from two distinct signal codes, persons of ordinary skill in the art will recognize that additional data frames including additional distinct signal codes may be transmitted at distinct power levels by an elongated body (e.g. 20) and received by a directional receiver (e.g. 30). For example, four data frames may be transmitted in succession by the elongated body (e.g. 20), each of the four data frames including a distinct signal code and transmitted at a distinct power level. A first data frame may, for example, be transmitted at a maximum power. A second data frame may, for example, be transmitted at 50 percent of the maximum power. A third data frame may, for example, be transmitted at 25 percent of the maximum power. A forth data frame may, for example, be transmitted at 5 percent of the maximum power.

According to an embodiment, a directional receiver (e.g. 30) may be adapted to select data frames including one of a plurality of signal codes. Selection may be based on power information. For example, the directional receiver (e.g. 30) may be adapted to select data frames corresponding to the signal code received at the lowest power level as measured by the directional receiver (e.g. 30) as long as good frame integrity is maintained.
