Abstract: Improved fixed receiver devices including both transmit and receive circuitry and operating on battery power are disclosed. An example transmitter/receiver location device includes a network interface to enable transmission and receipt of messages via a first communication medium and transmission and receipt of messages via a second communication medium. The example device includes a battery to provide power to the device, the battery to have a battery level and to be chargeable. The example device includes a memory to store instructions and data. The example device includes a processor to at least: process a beacon message received via the network interface; generate an information message for a location server based on location information from the beacon message and status information based on the battery level for the device; and adjust an operating state of the device based on the battery level.

Abstract: A reversible motor mount that can be attached to the gunnel on either side of a canoe is disclosed. The mount has a movable piece with a bracket to which said motor is clamped. The movable piece is locked in a first position when the motor mount is mounted on one side of the canoe and is locked in a second position when the motor mount is mounted on the other side of the canoe. No matter which side of the canoe said mount is attached to, and the movable piece is moved and locked in the appropriate position, and said motor is clamped to said bracket, the propulsion force from said motor when it is in operation will be downward and rearward.
