  • Patent number: 7239204
    Abstract: An amplifier circuit includes first (7A) and second (7B) operational amplifiers connected in a parallel configuration. A first terminal (12) of a first input resistor (5) is coupled to one input of both of the first (7A) and second (7B) amplifiers. A first terminal (15) of a second input resistor (6) is coupled to another input of both of the first (7A) and second (7B) amplifiers. A differential input voltage is applied between the second terminals of the first and second input resistors. The output signals of the first (7A) and second (7B) operational amplifiers are combined to produce an output signal (11AB) representative of feedback currents produced in the first (5) and second (6) input resistors. Upper and lower common mode input voltage ranges associated with the differential input voltage extend substantially above and below the upper and lower supply voltages, respectively, of the amplifier circuit.

  • Patent number: 7238623
    Abstract: The present invention provides a system (100) for aligning a dispensing apparatus (110) utilized within a semiconductor deposition chamber (102). A stationary reference apparatus (106) is disposed along the bottom of the deposition chamber. A self-alignment support system (122), comprising one or more support components (124), is intercoupled between the dispensing apparatus and a deposition system exterior component (112). The self-alignment support system is adapted to facilitate and secure repositioning of the dispensing apparatus responsive to pressure applied to the dispensing surface (114) thereof. A non-yielding offset component (126) is placed upon a first surface (108) of the stationary reference apparatus. The dispensing surface of the dispensing apparatus is engaged with the offset component, and pressure is applied to the dispensing apparatus via the offset component until a desired alignment is achieved.

  • Patent number: 7240120
    Abstract: A media player coupled to a network contains a processor, non-volatile memory, volatile memory, a driver, and input and output ports. The media player receives a media file over the network that contains an encoded media stream and a universal decoder. The player's processor converts or translates (or otherwise generates) the universal decoder into a player-specific decoder which may differ from the universal decoder. A library of routines stored in the non-volatile memory is used to create the player-specific decoder. The media stream downloaded to the media player may comprise audio, video, or any other desired type of media. In this manner, each media player can generate a decoder that differs, not only from the universal decoder, but may also differ from other media players thereby alleviating the burden on the media source from having to download the encoded media with a decoder specific to the target media player.

  • Patent number: 7240189
    Abstract: A fast resume of a computer from a low power mode to a normal operating mode captures a power down message from the operating system of the computer to devices connected thereto. In response to the captured message, the device manager is instructed to remove the device from the operating system. The computer is powered down with the device removed. The system is later powered up with the device removed, allowing for faster resume to normal operation. After the computer has returned to normal operation, the device manager reinstates the removed device. The program to capture the power down message can be above the device driver in the driver stock or be an application running in the user mode of the operating system.

  • Patent number: 7239436
    Abstract: A method for aligning consecutive scan lines of a mirror based visual system produced by the bi-directional scan of a resonant mirror is disclosed. The actual position for the mirror is determined or measured by any suitable method. The measured position of the mirror is used to generate a first trigger signal to start a scan line in a first direction at a selected location and to generate a trigger to start a scan line in the reverse direction at a second location.

  • Patent number: 7239664
    Abstract: A method selects the data rate for pulse code modulation upstream transmission by determining an approximate transmit power before the upstream transmission reaches a transmit equalizer based on a recorder power output and a distance halfway between an outermost constellation point and a point following the outermost point. The determined approximate transmit power is multiplied by the power of the transmit equalizer to determine a post-equalizer transmit value. A data rate is selected which is less than a predetermined regulatory limit.

  • Patent number: 7240344
    Abstract: An improved method is provided for performing register allocation in a compiler. This method determines the allocation of a plurality R of registers of a processor for use during the execution of a software program. The register allocation process is treated as a graph-coloring problem, such that an interference graph is constructed for the software program, the graph is simplified, and an R-coloring the interference graph to the extent possible is attempted. Then, spill code is inserted in the software program each for each uncolored node of the graph, a new interference graph is constructed, and the process is repeated. During the simplification process, nodes with degree greater than or equal to R are removed from the graph in an order dictated by a spill cost metric. During the coloring process, these same nodes are reinserted in the graph in an order dictated by reapplying the spill cost metric.

  • Patent number: 7239437
    Abstract: Apparatus and methods for removing jitter and stabilizing the feed back system of a torsional hinged device with minimal changes to the system. The stabilization is accomplished by spatially isolating the pivoting mirror structure from all drive, support and packaging structures to reduce air drag. The mirror structures may be further stabilized by tailoring the drive mechanism and the position of the mechanism to produce substantially pure rotational drive torque on the mirror.

  • Patent number: 7240277
    Abstract: A memory system or a digital signal processor (DSP) includes single-bit-error detection hardware in its level two (L2) memory controller to mitigate the effects of soft errors. Error detection hardware detects erroneous data that is fetched by the central processing unit and signals the central processing unit. The parity is generated and checked only for whole memory line accesses. This technique is especially useful for cache memory. The central processing unit can query the memory controller as to the specific location that generated the error and decide the next course of action based on the type of data affected.

  • Patent number: 7237081
    Abstract: A digital system is provided with a secure mode (3rd level of privilege) built in a non-invasive way on a processor system that includes a processor core, instruction and data caches, a write buffer and a memory management unit. A secure execution mode is thus provided on a platform where the only trusted software is the code stored in ROM. In particular the OS is not trusted, all native applications are not trusted. A secure execution mode is provided that allows virtual addressing when a memory management unit (MMU) is enabled. The secure execution mode allows instruction and data cache to be enabled. A secure execution mode is provided that allows all the system interruptions to be unmasked. The secure mode is entered through a unique entry point. The secure execution mode can be dynamically entered and exited with full hardware assessment of the entry/exit conditions. A specific set of entry conditions is monitored that account for caches, write buffer and MMU being enabled.
