Abstract: A disclosed vehicle wheel assembly includes a plurality of wheels, a plurality of rotary drive modules each having a respective rotation axis, and a plurality of rotatable arms, wherein each arm is arranged to extend radially from a rotation axis of a respective rotary drive module to couple the respective rotary drive module to a respective wheel. Each rotary drive module is operable to drive rotation of a respective rotatable arm about the rotation axis of the drive module, to thereby rotate a respective wheel about the rotation axis. A control module can sense stepped terrain, and control each rotary drive module to enable a vehicle to travel over the stepped terrain.

Abstract: A vehicle ramp assembly as disclosed includes a ramp for supporting one or more wheels of a vehicle and providing a bridge over stepped terrain on which the wheels of the vehicle can travel. The ramp can move among a first configuration where the ramp is stowed in the ramp assembly, a second configuration where the ramp extends from the ramp assembly, and a third configuration where the ramp is supports the vehicle wheels as it travels over stepped terrain. A drive mechanism for the ramp, and a carriage coupling the drive mechanism to the ramp enable rotation of the ramp. A secondary actuation system enables linear movement of the carriage along the ramp. A control module can drive the carriage around a curvilinear loop, such that the ramp is driven in a cycle from the first configuration to the second configuration to the third configuration to the first configuration.

Abstract: An ultrasound waveguide that is attachable to an ultrasound probe so as to identify a target area on a target object. The ultrasound waveguide has an ultrasound transducer coupling signal to be transmitted through a guide means. The ultrasound waveguide also has a positioning means for positioning the guide means in relation to the target area on the target object. The guide means is provided with a channel that provides a discontinuity within the guide means that causes a discontinuity in the ultrasound signal emitted by the probe. The presence of this discontinuity allow for proper alignment of the ultrasound waveguide with the target object.

Abstract: A system, method, and computer readable medium for providing professional and administrative services to clients (102) via computer, comprising first computing means (103) by which potential clients (101) obtain access to register with the system; second computing means (104),partitioned into a plurality of privated areas, wherein each private area is dedicated to a single client (102), other clients (102) not being granted access to said private area; and third computing means (106) to which the provider (105) of services has access but the clients (102) do not have access. The services may be the formation and organization of a corporation. The invention is most fully described in conjunction with the formation and organization of a Bermuda corporation.
