Patent number: 9687277Abstract: An implantation system for treatment of a defective curvature of the spinal column comprises an elongated element, a first bone fixation element being fixedly attached to said elongated element, a second bone fixation element, and guiding structure through which the second bone fixation element is slidably and contactingly connected to the elongated element. The elongated element has bending resilience and/or torsional resilience for applying corrective force action to the spinal column. A special arrangement of the guiding structure provides automatical adjustment of the corrective force action in dependence of growth of the spinal column. The system allows for good flexibility of the spine and for a natural healthy growth of the spine, while it avoids re-operations and implant adjustments.Type: GrantFiled: May 16, 2012Date of Patent: June 27, 2017Assignees: Stichting voor de Technische Wetenschappen, Universiteit TwenteInventors: Martijn Wessels, Edsko Evert Geert Hekman, Gijsbertus Jacobus Verkerke

Publication number: 20160087824Abstract: A phase-domain delta-sigma (??) modulator in a phase digitizer determines a demodulated phase error based on a phase-modulated frequency signal, in which a carrier frequency is modulated with a fundamental frequency and an associated phase, and a selected one of a set of reference signals, where the demodulated phase error represents a difference between the phase and a reference phase of the selected one of the set of reference signals. Moreover, a digital filter in the phase-domain ?? modulator filters the demodulated phase error. Furthermore, a latch in the phase-domain ?? modulator provides a bit stream by sampling one or more bits of the filtered demodulated phase error, where an average value of the bit stream represents the phase. Next, control logic in the phase-domain ?? modulator selects the one of the set of reference signals.Type: ApplicationFiled: February 24, 2015Publication date: March 24, 2016Applicant: Stichting voor de Technische WetenschappenInventors: Kofi A.

Patent number: 8896474Abstract: An analog-to-digital converter (ADC) is described. This ADC converts an analog signal into a digital value using a two-pass digitization process. In a first operation, coarse digitization is performed by an averaging converter based on a set of references. Then, in a second operation, fine digitization is performed by either another averaging converter or the same averaging converter based on a subset of the set of references that is progressively closer to an instantaneous value of the analog signal. For example, the coarse digitization may be performed by a low-resolution ADC stage and the fine digitization may be performed by a sigma-delta ADC, such as a single-bit sigma-delta ADC. Moreover, the other averaging converter may use dynamic element matching to shuffle reference elements used to generate the subset. In this way, the ADC may provide high resolution with reduced nonlinearity and quantization noise.Type: GrantFiled: February 11, 2013Date of Patent: November 25, 2014Assignee: Stichting voor de Technische WetenschappenInventors: Kofi A.
