Abstract: A gaming machine haptic feedback footrest, a host gaming machine, and processes of operation are provide to create haptic feedback. The haptic device is mounted along a lower front face of the cabinet and extends toward a player area in front of the cabinet. The haptic device includes a vibration plate positioned to tilt facing upward and toward the player area as a footrest. A base is provided with a suspension are mounted on the base carrying the vibrational plate and allowing vibrational movement thereof. One or more voice coil vibrating devices mechanically coupled to the vibrational plate along its lower side. An electronic amplifier electrically connected to the voice coil vibrating devices. A process includes activating the electronic amplifier to feed current to one or more voice coil vibrating devices in the haptic device according to the frequencies and durations, thereby activating the vibrational plate.

Abstract: A circuit is shown for arbitrating between inputs to provide all request inputs with the opportunity to be polled in substantially less time than is the case with known prior art round robin arbiters. This is accomplished by phase delaying the input clock to produce a plurality of different phase clock signals such that multiple arbiter circuits can be polled within a single clock cycle if the first few arbiter circuits do not have a request waiting. With proper speed of operation of arbiter circuits, the phase delay can be of a short enough duration that all of the arbiter circuits can be polled in a single clock cycle. With slower speed arbiter circuits, the total polling time can exceed one clock cycle but still be less than the number of clock cycles of prior art round robin circuits which typically was the number of arbiter circuits times a single clock cycle time duration.
