An automated ganged louver assembly is adjusted in orientation by an actuator in the louver header that suspends or supports the louver rotation mechanism. The actuator is energized in response to a determination of solar elevation, which is optionally from a light sensor output via a controller. The light sensor employs an optical element to detect at least one of the sun elevation and azimuth, as well as general exterior light levels. The solar elevation and azimuth can also be determined by calculations from the window orientation and latitude. The optical elements and the controller are coupled to at least one of the louvers or the louver header to provide a self contained system that does not require exterior power or controls, unless desired.

A stackable communications apparatus comprises modules to be powered on in a sequence. Each of the modules comprises components that perform an individual function or group of functions of the apparatus, each module in the plurality of modules comprising an individual chassis stackable with at least another individual chassis of at least another module in the plurality of modules. The modules comprise at least two modules establishing surface contacts by stacking. The surface contacts maintain, without physical cabling, power connection between the at least two modules. A preceding module in the sequence determines, via a power controller in communication with a power controller of a next module, a power requirement of the next module. The power controller of the preceding module in the sequence enables power to the next module if a remaining power from the preceding module is greater than the power requirements of the next module.

Stackable communications system

An audio system that comprises an audio server and individual speaker clients may be connected. Individual speaker clients may or may not be the same physical configuration. When the audio server detects each speaker client, the audio server configures each speaker to a particular purpose. This allows remote configurable speakers to be used for different features. Other audio devices may also be connected to the audio server.

A multimedia mobile personalization system provides a remote control that detects a user's electronic tag, e.g. an RFID tag. The remote control notifies a multimedia device of the user's identity. The multimedia devices tailors it operations to the user's preferences stored locally. Multimedia content such as broadcast or recorded television programs, music play lists, and the like could be sorted, displayed, or restricted, depending on the user identifier.

A multimedia mobile personalization system allows a user to record and play multimedia content on a set top box at a location other than his home using the user's preferences from his home DVR.

A multimedia signal processing system utilizes an easily manipulated, low-cost storage and display system that allows the user to view a television program and instantly review previous scenes within the program. The invention also allows the user to store selected programs while simultaneously watching or reviewing another. A versatile system architecture enables providing the invention in multiple configurations, each adapted to receive input signals from a different source. At the highest level, the system includes an input section and an output section. Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. Thus, several configurations are provided, each one requiring only minor system board modifications. The system architecture thus simplifies the design and manufacturing challenge presented by producing units to serve different markets, such as digital satellite, digital cable and analog cable.

A method and apparatus describes a stackable communications system. A system is modularized and stacked in various configurations. The interconnections between the modules may be by close proximity inductively coupled wireless Ethernet connections or a physical connection mechanism. Each module detects the power requirement of modules installed next to it. When a new module is installed, the module below determines the power requirements of the new module and whether adequate power is available. If adequate power is available, the new module is powered. An audio system that comprises an audio server and individual speaker clients may also be connected. Individual speaker clients may be the same physical configuration. When the audio server detects each speaker client, the audio server configures each speaker to a particular purpose. This allows the same type of speakers to be used for different features. Other audio devices may also be connected to the audio server.

A system for synchronization of data processing in a data processing system including multiple command queues is disclosed. The disclosed data processing system includes one or more processing engines associated with one or more command queues. The use of multiple command queues supports multiple priority levels, such that commands in higher priority queues may preempt commands in lower priority queues. Data processing is synchronized by queue commands that allow a processing engine to queue commands on the command queue of any processing engine in the data processing system, including its own. Multiple data dependencies are resolved by conditional queue commands and event counters that queue a command only when all of the conditions precedent to execution of a particular data processing command are satisfied. The hardware queuing of the disclosed invention advantageously synchronizes data processing with minimal software supervision and with minimal latency.

Distributed control and synchronization of multiple data processors

A system and method for coding colors and storing compensation factors used in converting colors from one color space to another color space. A color is converted from a first color space to a second color space using a color space converter. If one or more components of the second color is invalid in the second color space, a constant hue algorithm is used to create a compensated color which is valid in the second colors space. Specifically, a compensation determinator determines a compensation factor which is used in a compensation adjuster along with a constant hue algorithm to create the compensated color triplet. As a result of the constant hue algorithm, one of the color components of the compensated triplet is either zero or saturated. All except two bits of the storage space for the zero or saturated compensated color component are used to store the compensation factor. The other two bits are used to identify whether the color is zero or saturated and to identify the color component used to store the compensation factor. A color coding scheme is employed to identify valid colors from compensated colors and to identify the component used to store the compensation factor. An odd parity (and even, zero parity) is enforced across the LSBs for valid colors, and an even, non-zero parity is enforced across the LSBs for compensated colors. In addition, a value of zero for the LSB of a compensated color component identifies it as the component storing the compensation factor. In another embodiment, two bits of the alpha channel are used to code whether the color is valid, and to identify which color component in the associated triplet contains the compensation factor.
