Abstract: A video game/simulator system in a personal computer (PC) with game port and keyboard port includes a joystick includes a base and a joystick handle pivotally mounted on the base for two-dimensional movement. The joystick controller is connectable to both the game port of the personal computer and to the keyboard port via a second, throttle controller. The throttle and joystick controller inputs are reconfigurable to work with different video game/simulator programs by downloading a new set of keycodes from the personal computer via the keyboard port to a microcontroller and nonvolatile memory in the throttle controller. The throttle and joystick controller have variable inputs which can be input to the PC in either analog or digital form. The digital inputs can be calibrated by changing their corresponding keycodes. A multi-stage trigger switch is hingedly mounted on the joystick for actuation by a user's index finger.

Abstract: A process for treating high strength BOD containing liquors includes the step of mildly mixing and contacting the liquors with anaerobic bacteria and a powdered adsorbent support medium to remove a substantial portion of the organic matter and generate a methane fuel gas. Use of the powdered support medium at 0.1-20 g/l enables high removal of BOD in short treatment times, rapid clarification of treated liquors, and increased adsorbability of liquor color.In a subsequent decolorizing embodiment, digested and clarified liquors are contacted with reduced concentrations of powdered color adsorbent to produce a treated liquor low in dissolved organic matter and color.The spent streams of powdered adsorbent support medium-biomass and/or powdered color adsorbent are preferably regenerated and reused.
