Abstract: An electric utility vehicle with a frame, at least one drive motor mounted to the frame through a suspension assembly, a wheel mounted to the motor, and a steering assembly for steering the vehicle, wherein the steering assembly may be interchangeably reconfigured into a side driver configuration and a center driver configuration. The drive motor may be mounted at any one of four wheel positions. The suspension assembly may be interchangeably reconfigured as an independent A-arm suspension assembly and a trailing arm suspension assembly. The vehicle may include a controller coupled to the motor for independently supplying electrical power to each of two drive motors, such that during a turn an outside motor is supplied with more power than an inside motor. The controller may supply electrical power the drive motor according to a selected acceleration profile of at least two acceleration profiles.

Abstract: A four-wheel electric vehicle includes wheels having electric hub or geared, series wound induction drive motors mounted on one or more wheels. The vehicle requires no outside power transmission devices, such as differential gears or drive axles, to rotate the wheels. The vehicle includes a vehicle body adapted to accommodate seating for at least one adult person. The vehicle body is composed of several modular panels that may be releasably attached to one another to configure the vehicle for multiple applications. In one embodiment, the vehicle is a golf cart. In another embodiment, the vehicle is a multipurpose utility cart.

Abstract: An animal station is disclosed having a housing defining an interior with first and second openings formed through the housing in air flow communication with the interior. A first filter medium (a prefilter) is disposed to filter particulate matter from air flowing through the first opening and a second filter medium (a HEPA filter) is disposed to filter particulate matter from air flowing through the second opening. The second filter medium is selected to filter particulate matter finer than that filtered by the first filter medium. At least one movable animal cage rack is provided disposed adjacent either of the first and second openings. The rack has an interior providing air flow communication between ambient air and the adjacent opening when the rack is positioned adjacent the housing. A blower is provided for drawing air through an inlet and forcing the air through an outlet.
