Patent number: 9641164Abstract: A quadrature LC tank based digitally controlled ring oscillator (DCO). The oscillator structure incorporates a plurality of stages, each stage including a buffer and a series LC tank. Four stages are coupled together to create a 360 degree phase shift around a loop. The oscillation frequency of the oscillator is the same as the resonant frequency of each LC tank, therefore it avoids quality factor degradation of LC tanks found in the prior art. In one example embodiment, class-D amplifiers are used to drive each of the LC tanks. Capacitor banks before at the input and output of the buffers provide coarse and fine tuning of the frequency of oscillation. The high efficiency exhibited by these amplifiers results in very good phase noise performance of this oscillator. The oscillator utilizes a startup circuit to launch oscillation upon power on.Type: GrantFiled: November 19, 2014Date of Patent: May 2, 2017Assignee: Technische Universiteit DelftInventors: Massoud Tohidian, Robert Bogdan Staszewski, Ali Fotowat Ahmady, Seyed Amir Reza Ahmadi Mehr, Mahmoud Kamarei, Fabien Ndagijimana

Publication number: 20160347658Abstract: The invention provides a process for the production of a cementious material. The process comprises mixing cement starting materials and a particulate healing agent to provide the cementious material. The healing agent comprises coated particles, wherein the coated particles comprise bacterial material and additive. The bacterial material is selected from the group consisting of a bacterium, a lyophilized bacterium and a bacterial spore of a bacterium. The present invention solves these problems, as (substantially leakage-proof) tablets containing the actual healing agent may neither interfere with either the workability of the liquid mixture (“cementious material”) nor negatively affect properties of either mixture or final material (hardened concrete), even when applied in large quantities. During crack formation in cementious based constructions, the particles also crack, and healing agent is released.Type: ApplicationFiled: November 14, 2014Publication date: December 1, 2016Applicant: Technische Universiteit DelftInventor: Hendrik Marius JONKERS
