摘要： A platform-type wheelchair lift for mounting in the stairwell of a vehicle, such as a bus or train. The wheelchair lift includes a platform frame that is movable from a retracted position in which it is stowed underneath the vehicle to an extended position in which it extends out from the side or back of the vehicle. A wheelchair platform is movably coupled to the platform frame by a parallelogram linkage that allows the wheelchair platform to move between a lowered and a raised position. The wheelchair platform includes foldable outer and inner wheelchair barriers that prevent a wheelchair from moving off of the wheelchair platform during operation of the wheelchair lift. The wheelchair platform also includes a mechanical platform interlock mechanism. The platform interlock mechanism is moveable between an unlocked and a locked position. The platform interlock mechanism is in an unlocked position when no weight is placed on the wheelchair platform. In the unlocked position, the platform interlock mechanism allows the outer barrier to move between an upright barrier position, and a retracted position in which the barrier lies adjacent an upper surface of the wheelchair platform. When a weight such as a person or wheelchair is located on the wheelchair platform, the platform interlock mechanism moves into a locked position in which the outer barrier is prevented from moving between the upright position and the retracted position.

摘要： A system for targeting information on a computer network. The system involves categorizing a plurality of address pointers according to the content designated by the address pointer. The system further involves reading the address pointer which designates the content received by the user and determining which category or categories, if any, the address pointer is within. Information packets, such as advertisements, are targeted to selected categories. Once the category of an address pointer has been determined, an information packet targeted to that category is selected and transmitted to the user.

摘要： A method and system for suppressing or otherwise controlling the display of unrequested content while transitioning between first content and second content available over a communications system, such as the Internet, is disclosed. The system includes a browser device in communication with a host server and adapted to establish communication with a plurality of publishers to receive and display electronically published content, responsive to user inputs. The host server includes software with a controller and an override. Upon display of first content from a publisher and selection of second content, the controller is adapted to selectively display a default transition having intermediate content to the user prior to displaying the second content. The override is in communication with the controller and is adapted to direct the display of a defined transition to the user upon actuation, and thereby suppress the display of the default transition if the default transition is different from the defined transition.

摘要： A ramp assembly (20) having a frame attachable to a vehicle having a floor is disclosed. The ramp assembly further includes a platform coupled to a portion of the frame, a ramp having a weight, and a reciprocating mechanism disposed between the ramp and the platform coupled to a portion of the frame. The ramp assembly also includes a reciprocating mechanism disposed between the ramp and the platform for reciprocating the ramp between a deployed position and a stowed position in response to a load. The reciprocating mechanism counterbalancing the weight of the ramp during actuation of the ramp between the deployed and stowed positions to reduce the load required to reciprocate the ramp between the deployed and stowed positions.
