Abstract: A system for displaying multiple colors individually or in combination with one another. The system may emit red, green and blue light from light emitting diodes and may additionally provide white light to brighten the color provided by the red, green and blue light emitting diodes. The white light source may also be used to increase the power efficiency of the system, thus increasing the lifetime of the system for displaying multiple colors. The white light source may be used to backlight the color provided by the red, green and blue light emitted by the light emitting diodes, or may also be used as an additional light source to the light provided by the red, green and blue light emitting diodes.

Abstract: Methods and apparatuses are disclosed that provide increased control of backlit keys for a keyboard. Some embodiments may include controllers within the keyboard that are capable of dynamically programming illumination of the keyboard based upon interaction, where each key of the keyboard may be individually programmed in a dynamic manner. For example, a spell checking function may be executing on a computer system, and as the user types various words, the keyboard may dynamically program the illumination of keyboard controllers such that the next letter of the word being typed is illuminated by the keyboard. Also, different keyboard illumination schemes may be generated based upon mouse movements by the user and/or based upon which application is currently executing.

Abstract: Methods and apparatuses are disclosed that provide user interface behaviors for input devices with individually controlled illuminated input elements. Some embodiments may include receiving a request for input device lighting from a program, determining illumination information for light sources coupled to input elements of an input device based on the request, and dynamically controlling illumination of the light sources based on the illumination information. The illumination information may include brightness, color, and/or duration. The input device may constitute a keyboard with individually controlled illuminated keys. In some embodiments, the illumination may present information related to the program, functionality of input elements, and/or notifications.

Abstract: Systems and methods may provide user control of a computer system via one or more sensors. Also, systems and methods may provide automated response of a computer system to information acquired via one or more sensors. The sensor(s) may be configured to measure distance, depth proximity and/or presence. In particular, the sensor(s) may be configured to measure a relative location, distance, presence, movements and/or gestures of one or more users of the computer system.

For example, various contexts and/or operations of the computer system, at the operating system level and/or the application level, may be controlled, automatically and/or at a user's direction, based on information acquired by the sensor(s).

Such a computer system may be substantially or even entirely externally wire-free. Methods of image processing may involve a computer system with an integrated projector output.

Abstract: An interconnect structure includes in a first layer a clock line and a ground line running substantially parallel to the clock line, and a plurality of conductive regions lying in a second layer parallel to the first layer. The ground line is coupled to a source of ground potential. The conductive regions are aligned with the clock line and are disposed around a signal line routed in the second layer across the clock line. The conductive regions are electrically connected to the ground line, thereby forming a shield for the clock line that helps prevent clock signals propagated on the clock line from electromagnetically coupling with other signal lines. In one embodiment, a clock distribution network includes conductive regions (501, 503, 505 . . . ) in the metal layer below the clock line layer and two parallel ground lines (201, 203) in the same metal layer as the clock line (101).

Abstract: Disclosed is a system for automatically generating tables of buffer data which can be used during integrated circuit design to select appropriate buffers for signal distribution networks. The generated buffer data may be used by automated place and route systems to generate signal distribution networks having minimal skew. In the table, incrementally varying network features or criteria are provided (in the form of a table or list for example). Examples of such features include the length of a line connecting an L4 buffer to one or more L5 buffers and the number of L5 buffers driven by a single L4 buffer. For each incremental value of the network feature or features, one or more buffer types is specified. These buffer types have been previously modeled in the environment of the incremental value of the network features and found to meet certain criteria necessary to minimize skew.

Abstract: Disclosed is an automated method for adjusting wire lengths between connected circuit elements of an integrated circuit. The method includes the following steps: (1) receiving a value specifying a wire length that must be provided between terminals of two integrated circuit elements in the integrated circuit design; (2) defining a routing region in which the wire can be routed; and (3) automatically specifying a wire route including a serpentine section within the routing region for connecting the terminals. The serpentine section will include one or more legs sized to ensure that the wire route has the specified wire length. Specifically disclosed is the application of this method to size wiring between two clock buffers in separate and adjacent stages of a clock distribution network. The two clock buffers may be provided in third and fourth stages of the clock distribution network.
