Abstract: An elevated hunting blind has a hunting blind housing with a support frame. The elevated hunting blind has a substantially upright position, such that the support frame supports the housing, and a substantially level position, such that the support frame embodies a load-bearing trailer. Wheels may be attached to the support frame, such that when the elevated hunting blind is in the level position, the wheels are in contact with the ground to support the load-bearing trailer. An elongated hinging member has a first end having a trailer tongue suitable for attachment to a tow hitch and a second end rotatably connected to the support frame, so the trailer tongue can maintain constant attachment to the tow hitch on a vehicle in both the upright position and the level position.

Abstract: A master controller for managing items tagged with radio-frequency identification (RFID) tags includes a transceiver to transmit interrogation signals to the RFID tags and to receive response signals from the RFID tags. The master controller may also include a processor to determine the proximity of tagged items based on signal levels of the response signals, and to notify a user when certain ones of the tagged items are in a predetermined relation to a proximity threshold.
