Abstract: Methods and apparatus for the flexible provision of control data within large data structures. In one exemplary embodiment, DisplayPort is modified from its existing 8B/10B line coding to 128B/130B (or 128B/132B). In one embodiment, the 128B/130B (or 128B/132B) block includes: sixteen (16) eight (8) bit command or data symbols and a two (2) bit (or four (4) bit) synchronization header. The synchronization header may provide a fixed reference to the next command symbol (for example, the symbol immediately following the synchronization header). In one variant, each command symbol is split into a first and a second portion, where the first portion identifies a control function (control symbol), and the second portion provides a reference to the next command symbol.

Abstract: An emergency shower system attaches to a water pipe behind a wall and a valve mounted to the pipe. A frame is mounted to the wall around the valve, and a panel connected to the frame for covering an opening in the wall. The panel has an opening, and a plate is mounted to the panel to close the panel opening. A handle is mounted to the plate. A linkage is pivotally connected to the plate and to the valve. Vertical movement of the handle and plate are translated to rotational movement by the linkage to operate the valve. The handle only moves vertically at a constant distance from the wall. An eye/face wash station may be included. The eye/face wash station includes a pull down tray with spray nozzles. The nozzles are connected to another valve which is opened by the rotation of the pull down tray.

Abstract: Various methods and apparatuses that multiply the effects of feedback current on an amplifier. In an embodiment, a buffer circuit controls the transition rate on an output pad of the buffer circuit. An amplifier has an input terminal and an output terminal. The output terminal couples to the output pad. A feedback component couples feedback current from the output pad to the input terminal. A current mirror multiplies the effects of the feedback current on the input terminal without increasing the feedback current through the feedback component.

Abstract: A vehicle has a pair of opposite drive wheels driven by a dual path hydrostatic transmission. Steering and speed/direction controls are effected by changing the displacement and/or direction of fluid flow through the pair of reversible, variable displacement pumps that are respectively coupled to fixed displacement ground wheel drive motors. The control mechanism for accomplishing steering and/or speed/direction control includes a steering rack that is caused to pivot about a fixed post in response to steering wheel movement. A first crank arm is coupled for pivoting in concert with the rack and a second crank arm is coupled for pivoting in concert with a pivot plate about a second axis, the pivot plate having a pair of connection points respectively coupled to control arms of the pair of pumps by a pair of pump control rods. The pivotal motion of the steering rack is transmitted to the pivot plate by a tie-rod coupled between the first and second crank arms.

Abstract: A method and apparatus for reducing leakage currents in a high voltage tolerant I/O buffer. An I/O buffer designed to tolerate high external voltages by blocking such voltages at a passgate in a p-output path that uses a device between a p-driver gate node and a p-gate node of the passgate to ensure that the p-transistor of the passgate is turned on when the p-driver is driving the pad high. A second device isolates the p-gate node of the passgate from the pad until a pad voltage reaches a predetermined level. Once the pad voltage reaches the predetermined level, the device drives the voltage at the p-gate node of the passgate to that of the pad. Maintaining the p-transistor of the passgate on while the p-driver is driving the pad high allows a rapid hard shut-off of the p-driver as the I/O buffer tri-states the pad.

Abstract: The present invention provides an output buffer having a self back-bias compensating circuit that adapts the effective output transistor size to overcome current-reducing threshold voltage shifts caused by connection of the output n-wells to a high voltage. More particularly, this invention provides a circuit configuration in which bias level detection is used to switch in additional PFET legs under high back bias conditions. The extra driver legs are disabled under zero back bias. This compensates for the effect that different voltage switching environments have on PFET performance.

Abstract: A self-propelled windrower includes an engine compartment containing an engine-driven fan for pulling cooling air through a screen covering a circular air inlet leading into the compartment. The fan also is coupled for creating a suction in an air duct extending diametrically across the air inlet, the duct in turn being coupled to the center of a channel-like vacuum wand mounted for sweeping the exterior of the screen and removing airborne debris collected by the screen. Provided for rotatably supporting a drive shaft for the wand is a bearing support member including a cylindrical portion having an end fixed to a mounting plate secured to the air duct, the cylindrical portion having an interior end section receiving an outer race of a roller bearing having an inner race receiving and being fixed to the wand drive shaft. An electric drive motor is located within said compartment and mounted to said air duct at a side thereof remote from said screen.

Abstract: A steering and ground speed control mechanism of a vehicle equipped with a dual-path hydrostatic drive system includes a pivot plate fixed to a vertical pivot post at a location between and equidistant from a pair of locations respectively linked to a pair of pump displacement control arms of a pair of pumps respectively coupled for delivering fluid to right- and left-hand drive motors coupled to right- and left-hand ground wheels. A train of elements for transferring steering inputs from a steering wheel to the pivot plate includes a timed belt and sprocket set with one of the sprockets being fixed to the pivot post and the other mounted to a fixed post together with a quadrant-shaped steering rack for pivotal movement about the fixed post in concert with the rack. Pivoting the pivot plate in opposite directions from a centered position causes different displacements of the pumps and, hence, in the two drive motors being driven at different speeds.
