Abstract: This document presents a multiple alert and deterrent device that may be used in underwater environments to present visual and audio signals to alert other divers, and simultaneously generate a voltage that serves as a deterrent to sharks. The activation of all alert and deterrent components occurs simultaneously when a user activates the device. Device activation may occur as the result of a user selection, or may be configured to occur automatically when a user removes the device from a connection to the user's clothing or any equipment associated with the user to which the device is attached.

Abstract: In one embodiment, a method includes receiving, from a decoder connected to a wireless receiver for communication with a remote apparatus, first error data that indicates a current error rate that corresponds to a first inbound data packet received from the remote apparatus. Based in part on the first error data, it is determined whether the remote apparatus should increase a current signal to noise ratio. If so, then a first outbound data packet is sent to an encoder connected to a wireless transmitter. The first outbound data packet includes first link conditioning request data that indicates a current signal to noise ratio for one or more data packets received from the remote apparatus based at least in part on the first error data. The remote apparatus increases signal to noise ratio of transmissions in response to receiving the outbound data packet.
