Abstract: A direct digital frequency synthesizer and a synthesizing method thereof. The direct digital frequency synthesizer uses a hybrid digital to analog converter, which matches output data of a phase accumulator to a sine wave amplitude using a hybrid DAC, including a non-linear DAC and a linear DAC. The non-linear DAC outputs a direct base point current using some bits of output data of a phase accumulator, causing the linear DAC to output a gradient current based on gradient information generated using other bits of the output data of the phase accumulator. These currents are summed for the analog output.

Abstract: An instrumentation delivery unit which supports hand-held dental instruments. In one example first and second housing members form a sealed chamber. When the members are separated, access is permitted to the interior of the chamber, e.g., for maintenance purposes. A first portal suitable for connection to a vacuum line provides a partial vacuum in the chamber, and second portals provide connection via second vacuum lines between the chamber and dental devices to operate the devices. The housing includes hand piece holders each of an initial diametric size for receiving hand pieces up to a maximum diametric dimension, with one of the hand piece holders formed along two adjoining ones of the housing members. The adjoining housing members secure inserts between one another to provide a second diametric size smaller than the initial diametric size to thereby selectably accommodate hand pieces having a smaller diametric dimensions.

Abstract: Silicon Carbide (SiC) probe designs for extreme temperature and pressure sensing uses a single crystal SiC optical chip encased in a sintered SiC material probe. The SiC chip may be protected for high temperature only use or exposed for both temperature and pressure sensing. Hybrid signal processing techniques allow fault-tolerant extreme temperature sensing. Wavelength peak-to-peak (or null-to-null) collective spectrum spread measurement to detect wavelength peak/null shift measurement forms a coarse-fine temperature measurement using broadband spectrum monitoring. The SiC probe frontend acts as a stable emissivity Black-body radiator and monitoring the shift in radiation spectrum enables a pyrometer. This application combines all-SiC pyrometry with thick SiC etalon laser interferometry within a free-spectral range to form a coarse-fine temperature measurement sensor.

Abstract: A tape drive for use in for example a transfer printing apparatus to drive a printer ribbon. The printer ribbon is mounted on two spools each of which is driven by a respective stepper motor.
