Abstract: A transport vehicle for transporting payloads is provided. The transport vehicle includes primary and secondary chassis, and first and second sets of wheels for supporting the respective primary and secondary chassis. A guide arrangement is mounted on the primary chassis and the secondary chassis is slidably mounted on the guide arrangement. The primary and secondary chassis are parallel and spaced apart from each other. A payload lifting arrangement is positioned on a top surface of the secondary chassis to lift a payload. When a weight of the payload is below or equal to a threshold weight, the weight is distributed across the second set of wheels by way of the suspension arrangement. When the weight of the payload exceeds the threshold weight, the weight is distributed across the first and second sets of wheels by way of the guide arrangement and the suspension arrangement, respectively.

Abstract: A memory device includes an electrical line operably coupled to a plurality of memory cells, and a switchable impedance driver operably coupled to the electrical line. An electronic circuit includes a first driver having a first output impedance, and a second driver having a second output impedance that is less than the first output impedance. The first driver and the second driver are operably coupled in parallel to an output of the electronic circuit. The electronic circuit includes logic circuitry to enable the second driver during switching of a digital output of the driver. A method includes driving an output with both the first driver and the second driver when an input switches between logic levels, and disabling the second driver when the output reaches a desired logic level following the switch between logic levels of the input.

Abstract: Apparatus for playing a quiz game of skill playable by remotely located participants simultaneously logged in and competing against each other, said game including inserted advertising comprising: a network structure for allowing multiple players to engage in a quiz game using an electrical or electronic network for data exchange; and a control system for establishing a virtual universe for said quiz game that can be accessed by any of said multiple players via an electrical or electronic network, said control system being operative for providing quiz questions and inserted advertisement for each of said multiple players; said control system including: text means for receiving a text input from each one of said multiple players, said text input being in response to the quiz question which is in the form of a multiple choice question.
