Abstract: A method of providing ride-through capability in a chiller/refrigeration system employs a variable speed drive with an active converter stage, a DC link stage and an inverter stage for providing variable frequency and voltage to power at least one motor. An induction motor is coupled to the output of the inverter stage for driving a compressor in the chiller/refrigeration system. The ride-through method comprises operating the active converter to regulate the DC link voltage of the DC link stage to a predetermined voltage level until the current through the active converter equals a predetermined current limit, then transferring regulation of the DC link to the inverter upon reaching the current limit of the converter. The compressor is unloaded, and the power flow through the inverter is reversed to maintain the voltage level of the DC link stage.

Abstract: Power is controlled by increasing the power level of a wireless transmission if a number of packet errors in a short observation window exceeds a first threshold. Power is controlled by decreasing the power level of the wireless transmission if a number of packet errors in a long observation window falls below a second threshold. In various embodiments, power is controlled based on packet error rate using both open and closed loop feedback to manage power at an increased level of granularity.

Abstract: A compact optical tracking system for magnetic tape is disclosed which is independent of the magnetic format and head structure which can generate a position error signal without encoding on the servo track. A plurality of optical servo modules is arranged in a linear array. Each optical servo module contains an optical beam source, preferably a laser, an optical beam interference composite hologram for producing a predetermined pattern on a target and at least one detector for detecting an optical beam reflection. A position correction signal is generated by one or all of the optical servo modules for re-positioning a magnetic head, which reduces the error in the correction signal from tape degradation and dimensional changes. Reference grating may be added to provide further position calibration prior to the tape being positioned over the head.

Abstract: Structures having low-k multilayered dielectric diffusion barrier layer having at least one low-k sublayer and at least one air barrier sublayer are described herein. The multilayered dielectric diffusion barrier layer are diffusion barriers to metal and barriers to air permeation. Methods and compositions relating to the generation of the structures are also described. The advantages of utilizing these low-k multilayered dielectric diffusion barrier layer is a gain in chip performance through a reduction in capacitance between conducting metal features and an increase in reliability as the multilayered dielectric diffusion barrier layer are impermeable to air and prevent metal diffusion.

Abstract: A signal recording/playback apparatus includes a recording data converter. The recording data converter converts on a data pattern having a large influence on adjacent tracks on an optical disk, and outputs the converted data to an optical pickup. Specifically, by performing a data converting process in which, for a data pattern having a predetermined length of at least consecutive bits having identical values, part of the bits is inverted based on a conversion table, the recording data converter compensates a recording operation. Alternatively, instead of inverting the bits, by controlling the output power and pulse width of a laser, the recording operation is compensated. The signal recording/playback apparatus includes a played-back data converter. In the data playback mode of the signal recording/playback apparatus, the data converted by the recording data converter is identified and decoded into the original data by the played-back data converter. The played-back data converter outputs the original data.

Abstract: A user may utilize a prototyping environment to create a sequence of motion control, machine vision, and/or data acquisition (DAQ) operations, e.g., without needing to write or construct code in any programming language. For example, the environment may provide a graphical user interface (GUI) enabling the user to develop/prototype the sequence at a high level, by selecting from and configuring a sequence of operations using the GUI. The prototyping environment may provide an application programming interface (API) which enables an external caller program to invoke execution of a particular sequence by the prototyping environment.

Abstract: An optical alignment device holds fiber collimators in place with extremely good mechanical and environmental stability. The device includes a ball with a hole traversing the ball, an upper clamping block with a first inner concave spherical surface and a lower clamping block with a second inner concave spherical surface. The hole includes a shape that can accommodate or contact an optical component whose alignment is to be controlled. The ball, together with the enclosed optical component is firmly held between the first and second inner concave surfaces of the clamping blocks, which are tightened against the ball with screws. When firmly clamped within the concave surfaces, the ball is prevented from accidental movement but can still rotate about any axis to align the optical component. Once alignment is achieved, the optical component and the ball are secured in place by epoxy, glue, solder or other suitable adhesive.
