A water skier alert system is used with a boat towing a water skier via a rope and tow bar handle secured thereto. A radio receiver is adapted to be positioned on the boat towing the water skier for receiving wireless radio signals transmitted from the tow bar handle in response to a skier down condition or water skier actuation of a desired water skier condition. A display is operative with the receiver and has indicia on the display that are actuated by the wireless transmitter signals and indicative of the skier down condition and each of desired water skier conditions. The tow bar handle includes at least one battery and a pressure sensor positioned at the grip portion and sensitive to hand and/or finger pressure exerted by a water skier. Control actuators are positioned along the grip portion and indicate a desired water skier condition. A wireless radio transmitter generates wireless signals indicative of a skier down condition when pressure is no longer exerted on the pressure sensor and desired water skier conditions after water skier actuation of the control actuators.

An asynchronous device, comprising: an address input buffer for receiving an input address bus and generating logic true and logic complement signals of each address input signal of the input address bus, wherein a signal transition appearing on a logic true signal is separated in time from a signal transition appearing on a corresponding logic complement signal; and decode logic for receiving the logic true and logic complement signals of the address input buffer and asserting at least one of a plurality of decode output signals based upon a value of the logic true and logic complement signals; control circuitry responsive to the logic true and logic complement signals for generating a control signal having a logic value based upon the presence of transitions appearing on the logic true and logic complement signals, the control circuitry having a pull-up or pull-down device coupled to the control signal and providing a first impedance level initially when in a logic state indicative of an absence of the transitions, and a second impedance level a predetermined period of time thereafter when in the logic state indicative of an absence of the transitions; and circuitry for performing an operation responsive to a decode output signal bein
