Abstract: An air management system for a vehicle having a supply tank, a system controller integrated with the supply tank, a first pneumatic circuit pneumatically connected to the system controller, and a second pneumatic circuit pneumatically connected to the system controller. The system controller adjusts independently air pressure of the first pneumatic circuit and the second pneumatic circuit without establishing pneumatic communication between the first and second pneumatic circuits. The system controller establishes pneumatic communication between the first and second pneumatic circuits when the system controller is not adjusting independently the air pressure of the first pneumatic circuit and the second pneumatic circuit.

The first pneumatic circuit includes a first leveling valve configured to adjust independently the height of a first side of the vehicle. The second pneumatic circuit includes a second leveling valve configured to adjust independently the height of a second side of the vehicle. The first and second leveling valves are configured to establish pneumatic communication between the first and second pneumatic circuits when the first leveling valve is not independently adjusting the height of the first side of the vehicle and the second leveling valve is not independently adjusting the height of the second side of the vehicle.

Abstract: A power system includes an input node connected to a power source of a vehicle, an output node connected to a load of the vehicle, a super capacitor connected to the output node, a battery connected to a first node, and a contactor coupled between the battery and the super capacitor. The contactor is configured to be turned on to charge the super capacitor with power from the battery in a fast charge mode.

Abstract: In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.

Abstract: Systems, methods, and computer-readable media for simulating the course of an event or for collecting data for the simulation are provided. A processing unit can receive attributes of synthetic populations and corresponding forecasts of progress of an event, e.g., an epidemic. The processing unit can determine a disease model based on the forecasts and historical data of the event. The disease model can be associated with at least one attribute of each of the synthetic populations. The processing unit can determine a forecast of the progress of the event based on the received forecasts and weights associated with user accounts. In some examples, the processing unit can receive the attributes, present via a user interface a plurality of candidate forecasts of an epidemic, and receive via the user interface a forecast, e.g., rankings or data, of the epidemic with respect to the synthetic population indicated by the attributes.

Abstract: An interactive exercise apparatus engages a user's mind and body. The apparatus comprises an exercise mechanism, a steering mechanism, and a control mechanism for manipulation by the user to achieve exercise, to indicate a direction of motion, and to interact with virtual objects in a simulated environment. The exercise mechanism can be, for example, the steps of a stair climbing simulator or the pedals of a bicycle, preferably a recumbent bicycle. A simulated environment (e.g., an interactive simulated three-dimensional environment or an interactive simulated three-dimensional fluid environment) is generated by a computer and displayed on a display system for the user. In one embodiment, the simulated environment comprises an enclosed space representing a game field. In this embodiment, an interactive competitive ball game is played using networked exercise apparatus.
