Method and apparatus for measuring contraction characteristics of engineered heart tissue constructs
Patent number: 10172712Abstract: The invention is directed to a novel method for measuring contraction characteristics of engineered heart tissue constructs (16) which is based on the mechanical coupling of the construct (16) to a support element (8) which comprises or is mechanically coupled to a piezoelectric element (10). An apparatus (1) for carrying out the method of the invention is also provided.Type: GrantFiled: March 25, 2014Date of Patent: January 8, 2019Assignees: Universitätsklinikum Hamburg-Eppendorf, Technische Universität Hamburg-HarburgInventors: Thomas Eschenhagen, Ingra Mannhardt, Jörg Müller, Christoph Warncke, Jördis Weiser -
Patent number: 9702975Abstract: The present invention relates to a lidar measurement system for the detection of the presence and/or motion of particles and/or objects in a space region remote from the lidar measurement system and comprising an interferometer arrangement, as well as to a corresponding method using such a measurement system. The interferometer arrangement comprises a continuous wave laser source (2), a photodetector arrangement (7), and optical components which are adapted to split light (23) emitted by the continuous wave laser source (2), to guide it along a first optical path constituting a measurement branch (4) and along a second optical path, which is separate from the first optical path and constitutes a reference branch (5), and to eventually have it incident in a spatially coherently superimposed manner onto the photodetector arrangement (7).Type: GrantFiled: November 11, 2013Date of Patent: July 11, 2017Assignee: Technische Universität Hamburg-HarburgInventors: Ernst Brinkmeyer, Thomas Waterholter

Patent number: 9494027Abstract: Control device (100) controlling a drilling operation and methods by which the dynamics of the continuum in question can be divided into superimposed waves, of which the wave traveling in the direction of the actuator and/or drive (10) is compensated by the actuator. This prevents reflection of the energy on the actuator. By using two sensors (30, 40) the wave traveling towards the actuator (10) and the wave traveling away from the actuator (10) can be calculated separately from one another, so that both the parameters of the wave traveling toward the actuator and the parameters of the wave traveling away from the actuator can be determined in order to be able to perform a control of the driving device of the drill string (20) on this basis.Type: GrantFiled: September 21, 2011Date of Patent: November 15, 2016Assignees: TECHNISCHE UNIVERSITAT HAMBURG-HARBURG, TUTECH INNOVATION GMBHInventors: Michael Steidl, Edwin Kreuzer
