Abstract: A piece of exercise equipment includes an electronic game of chance connected thereto. A switch or other device may also be connected to the combination system to operate the electronic game of change when the piece of exercise equipment is in use. The combination system also includes a controller which detects a combined action of playing the electronic game of chance and using the exercise equipment. The system electronically connects the gambling device to the piece of exercise equipment and detects when an operator is using both the exercise equipment and the electronic game of chance simultaneously.

Abstract: A frequency agile signal generator provided for emulating a communication signal of predetermined frequency and modulation characteristics including frequency hopping. The signal generator includes a digital controller such as a microprocessor or microcomputer for generating digital command signals specifying the desired characteristics of the output signal. In response to the digital command signals, a base digital frequency signal representing the desired base or center frequency of the output signal is generated by a number controlled oscillator in response to a digital frequency control signal. The digital command signals also control the generation of an analog modulation signal having desired modulation characteristics.
