A visual indicator for the stage can be calculated based on the distances between at least two gates in the stage. The visual indicator can then be displayed. The visual indicator can be a color and the relative distance can be indicated by brightness, hue or saturation, etc. Alternatively, the visual indicator can be a pattern and the relative distance between at least two gates can be indicated by darkness of the pattern.

Abstract: A system and method for reducing timing errors in automated test equipment (ATE) offering increased data rates for the testing of higher-speed integrated circuits. Embodiments provide an effective mechanism for increasing the data rate of an ATE system by delegating processing tasks to multiple test components, where the resulting data rate of the system may approach the sum of the data rates of the individual components. Each component is able to perform data-dependent timing error correction on data processed by the component, where the timing error may result from data processed by another component in the system. Embodiments enable timing error correction by making the component performing the correction aware of the data (e.g., processed by another component) causing the error. The data may be shared between components using existing timing interfaces, thereby saving the cost associated with the design, verification and manufacturing of new and/or additional hardware.

Abstract: Methods and apparatus are provided for improved phase linearity in a multi-phase based clock/timing recovery system. Averaging and interpolation techniques improve phase linearity in a multi-phase clock system. A multi-phase output clock is generated in accordance with one aspect of the invention by generating a plurality of clocks each having a substantially similar frequency and a different phase; applying each of the plurality of clocks to at least one corresponding amplifier such as a differential pair circuit; and summing an output of the corresponding amplifiers to generate the multi-phase output clock. A multiple-stage averaging operation can provide further linearity improvements.

Abstract: The present invention is directed towards systems and methods for dynamically deploying and executing an acceleration program on a client to improve the performance and delivery of remotely accessed applications. The acceleration program of the present invention is automatically installed and executed on a client in a manner transparent to and seamless with the operation of the client. An appliance may intercept a request of the client to establish a communication session or connection with a server, and transmit the acceleration program to the client. In some cases, the appliance determines whether the application being accessed by the client can be accelerated and only provides the acceleration program if the application can be accelerated. Upon receipt of the acceleration program, the client automatically performs a silent installation of the acceleration program and executes the acceleration program upon completion of the installation.

Abstract: Molds and processes that permit high-speed, mass production of retaining wall blocks having patterned or other processed front faces, as well as retaining wall blocks formed by such processes. The invention permits the front face of the block to be impressed with a pattern or otherwise directly processed, to allow the formation of pre-determined block front faces, while at the same time facilitating high-speed, high-volume production of blocks. A mirror image of the desired pattern can be created on a stripper shoe by selecting a desired three-dimensional surface from a naturally occurring or man made object and digitally scanning the selected three-dimensional pattern to create scanned data. The scanned data can then be used to machine a face of the stripper shoe that is the mirror image of the selected pattern.

Abstract: Provided herein are methods and systems to screen for subjects at risk for retinal-associated eye diseases or to monitor the progression/regression thereof. Generally, the method comprises simultaneously or sequentially displaying to a potentially at-risk individual targets of parallel and nonparallel lines, obtaining an orientation discrimination threshold based on the subject's selections and correlating an increase in the threshold compared to that of a normal control or to a previous threshold measured for the subject as indicative of risk for a retinal-associated eye disease or a progression of the eye disease. Also provided are program storage devices and computer program products effective to store instructions or source code to perform the methods.

Abstract: An electrically programmable and erasable non-volatile semiconductor memory such as a flash memory is designed into a configuration in which, when a cutoff of the power supply occurs in the course of a write or erase operation carried out on a memory cell employed in the non-volatile semiconductor memory, the operation currently being executed is discontinued and a write-back operation is carried out to change a threshold voltage of the memory cell in the reversed direction. In addition, the configuration also allows the number of charge-pump stages in an internal power-supply configuration to be changed in accordance with the level of a power-supply voltage so as to make the write-back operation correctly executable. As a result, no memory cells are put in deplete state even in the event of a power-supply cutoff in the course of a write or erase operation.

The input shaft extends in a longitudinal direction. The drive unit comprises a power-split device, of which the input member is connected to the input element and of which the output members are connectable to driveshafts of the axle. The axle is oriented in a direction transverse to the longitudinal direction. The input member and the output members of the power-split device are mounted rotatably about axes parallel to the longitudinal direction. An angle drive is arranged in each case between the output members of the power-split device and the driveshafts.

Abstract: A method of determining a useful skew for a circuit design includes computing a slack value for each sequential cell in the circuit design, identifying modifiable sequential cells in the circuit design, and computing a target delay for each modifiable sequential cell. One or more sequential cells are discarded based on the slack values. A target slack value for each remaining sequential cell is determined. The remaining cells are sorted based on the target slack values to determine a minimum target slack value, and a delay for each cell is determined based on the minimum target slack value.

Abstract: A method for communication includes configuring a plurality of ring nodes to communicate over a communication network that includes two or more overlapping communication rings, each ring including two unidirectional ringlets in mutually-opposite directions. A data packet including one or more header fields is accepted at an ingress ring node. An egress ring node to which the data packet is to be forwarded by the ingress ring node is determined. A subset of the rings including one or more common rings that are connected to both the ingress and egress ring nodes is identified. A ringlet of a ring among the one or more common rings is selected responsively to a respective value of at least one of the header fields of the packet. The data packet is forwarded from the ingress ring node to the egress ring node over the selected ringlet.
