Abstract: A method for proportional state space based scheduling of gain within a machine includes generating a speed error value and when the speed error value is substantially nonzero producing an implement position difference value representing the amount by which an implement position differs from a position that would provide a desired machine speed. The method then converts the implement position difference value to a desired implement position command and differences the desired implement position command and a position signal indicative of the current implement position to produce an implement difference value.

Abstract: A screwdriver is disclosed including a handle, a shaft, and a gearbox disposed between the handle and the shaft. The gearbox is structured and arranged to cause rotational motion of the shaft at a first rate due to rotational motion imparted on the handle at a second rate. In an embodiment, the first rate is greater than the second rate.

Abstract: Articles of breakdown furniture (e.g., a desk and a TV stand) that can be quickly and easily assembled and disassembled by a user without the need for traditional tools, in a relatively short time, and with minimal assistance. In its disassembled condition, the furniture is advantageously adapted to be packaged and transported in compact shipping containers. A removable top is detachably connected between a pair of opposing sides or legs by locking pins which slide through lock bodies affixed to the detachable top for receipt by respective pin holes formed in the sides. A back panel is connected between the pair of opposing sides by connectors which project from ends of the support panel for removable receipt by slotted brackets affixed to the sides. In the case of the desk, a removable pull-out drawer is located below the removable top to be slidably received by grooves formed along the sides.

Abstract: A drawer front system including an interchangeable front panel adapted to be detachably connected to the face of a drawer without requiring special skill or the use of tools. The interchangeable front panel is ideally selected from a variety of front panels having different aesthetics so that the ornamental appearance of the drawer front can be easily changed to correspond with a change in mood, home or office relocation, or living/working arrangement of a user. A pair of panel mounts (e.g., rails) project outwardly from the face of the drawer. A corresponding pair of mounting recesses (e.g., channels) are formed in the interchangeable front panel to slidably receive respective ones of the panel mounts, whereby the detachable front panel and the drawer face are disposed in face-to-face alignment with the front panel visible to passersby.

Abstract: A method and apparatus for facilitating shipping pick-up services and managing shipping information. A customer may register with a shipping information management system (SIMS) to provide customer preferences and billing information to enable transparent shipping services with the SIMS. When a customer purchases postage electronically, an application on the customer's computer detects postage printing activities and extracts shipping information. The extracted shipping information is transmitted to a SIMS server, from which pick-up instructions are automatically issued to a pick-up service provider. Payment for the pick-up service may be verified at the time the pick-up instruction is issued. The SIMS apparatus may also provide tracking status to customers, as well as shipping information data-mining services to shipping service providers.
