Abstract: An input device includes a control surface for a color correction system. The control surface includes a housing with an upwardly facing control panel. The control panel has a proximal edge which is nearest a user and a distal edge that is furthest from a user in normal use. The control panel includes a plurality of controls. The plurality of controls includes: a plurality of trackballs, wherein each trackball comprises a ball and a control ring, said ball cooperating with at least one encoder to generate a multi-dimensional control signal based on motion of the ball, and said control ring cooperating with at least one encoder to generate a one dimensional control signal based on the rotational motion of the ring, wherein the ball of said trackball is mounted concentrically with said control ring; a plurality of control buttons; and a plurality of knobs coupled to respective rotary encoders.

Abstract: Techniques for power-density-based clock cell spacing and resulting integrated circuits (ICs) are disclosed herein. In one example, the techniques determine power-usage density for different types of clock cells, as power-usage density relates to heat and IR droop. With the power-usage density for each type of clock cell determined, the techniques assign a keep-out region for each type of clock cell that is not fixed for all types of clock cells. These regions are instead based on the heat and IR droop corresponding to estimated power-usage density for each type of clock cell. Clock cells are then placed in a layout of an IC. The resulting IC has clock cells spaced sufficiently to reduce heat and IR droop while concurrently having excellent timing closure and performance.

Abstract: A flip-flop is provided that includes a master latch clocked according to a first delay during a normal mode of operation and clocked by a smaller second delay during a scan mode of operation.

Abstract: Disclosed is an inrush current control circuit for controlling current into a high-current circuit block. The inrush current control circuit comprises a number of distributed switches and a digital control circuit coupled to at least one of the distributed switches. The digital control circuit is configured to switch a first group of the distributed switches in response to an enable/disable signal. The digital control circuit is further configured to switch a second group of the distributed switches after a first programmable delay. According to one embodiment, a method comprises switching a first group of distributed switches by a digital control circuit of an inrush current control circuit in response to an enable/disable signal, and switching a second group of the distributed switches by the digital control circuit after a first programmable delay, thereby resulting in regulation of a flow of an inrush current.

Abstract: A rugged, releasably attachable or interchangeable optical alignment system well suited for use as with pistol sights includes a sight body carrying a leaf spring locking member adapted to releasably engage a pistol's indentation. The sight body's leaf spring member is inserted into the pistol in a side opening transverse receiving notch with a pinned end of the leaf spring locking member sliding transversely over the pistol indentation's end wall open segment (at the side of the pistol). The user slides the sight base toward the bore's central axis to its fullest transverse extent, whereupon the leaf spring member's first end abuts the indentation's closed end wall. At this moment, the leaf spring locking member's free distal second end springs down and releasably engages and abuts the indentation's end wall, thus releasably locking the sight base to the pistol.
