Title: Driver circuitry providing weighted sum signals and modulation of edge rate and voltage swing
Inventor: SOMASEKHAR DINESH
IPC: G06F13/40
Filed: 2007-12-19
Abstract: An interface circuit 200, suitable for inter-chip or intra-chip communication, contains edge detection circuitry 206, providing a short pulse at a rising and falling edge of a data signal, and driver circuitry 208 comprising a plurality of drivers, e.g. tri-state drivers, coupled in parallel. Driver circuitry provides a weighted sum signal and the drivers may be used to selectively adjust the amount of driver current provided onto a connection. Edge rate or voltage swing of the weighted sum signal can be determined by the number of drivers that are turned on. Component 214 receives an inverted data signal and modulates swing and edge rate of a leading edge signal; component 212 modulates the trailing edge. The weighted sum signal may be a sum of return-to-zero (RZ) and non-return-to-zero (NRZ) components of the data signal and can be recovered using an inverter. Interface circuit 200 may be used when stacking dies (102, 104, fig. 1).

Title: Brake dragging detection means
Inventor: CAHILL ERIC D
IPC: B60T17/22
Filed: 2009-12-17
Abstract: Whether a brake is dragging is determined based on post-takeoff spindown data. Spindown is the natural deceleration of the wheels after takeoff. The method comprises measuring spindown of a wheel to obtain spindown data. The spindown data is compared with a spindown envelope, and notification is provided if the spindown data indicates a wheel is spinning down outside a spindown envelope. The spindown envelope may be based at least in part on past data, may be empirical data, may be based on real time spindown from other wheels or may be based on gear retract braking. The spindown data may be determined to be outside the spindown envelope based on at least one of wheel energy, wheel velocity, wheel distance, wheel acceleration or wheel jerk rate.

Abstract: 484,351. Delivering material from hoppers. SIMON, Ltd., H., and BRIAN. J. C. April 9, 1937. No. 10118, [Class 78 (i)] Hoppers, of the kind in which one or more rotating arms c sweep the material from an upper chamber b through one or more holes in the base to a lower chamber d also provided with rotating arms f delivering to a shoot g, are fitted with a pivoted flap i which automatically regulates delivery from b in accordance with the height of material in d, thus preventing clogging due to bridging in the chamber d. Clogging in the region of the outlet e causes pressure on the hanging tail-piece k of the flap and swings it counterclockwise against the action of the counterweight m thus raising the flap to cover the exit from the chamber b to a greater or lesser extent. Where multiple exits are provided from chamber b a separate flap may be fitted to each exit.
