Patent number: 11974848Abstract: A sensor circuit that is capable of sensing of neural action potentials is disclosed. The circuit can be designed to minimize power dissipation and total silicon area so that it can be incorporated into a massively parallel sensor array and ultimately implanted in the body (e.g. into the brain) in a safe manner. The circuit can also be designed to be tunable such that it can be optimized in silico prior to fabrication, and can be optimized through the use of controllable current sources after fabrication.Type: GrantFiled: October 2, 2019Date of Patent: May 7, 2024Assignees: CAELESTE CVBA, PARADROMICS, INC.Inventors: Matthew R. Angle, Robert Edgington, Aamir Ahmed Khan, Bart Dierickx, Peng Gao, Amir Babaiefishani, Ahmed Abdelmoneem, Bert Luyssaert, Jean Pierre Vermeiren

Patent number: 8064063Abstract: A device (100) for assisting in optical characterisation of a sample fluid. The device can comprise a substrate (102) with at least one measurement reservoir (104) adapted for filling with the fluid (106) in a filling direction. The device (100) thereby is adapted for receiving an illumination beam (108) for illuminating the fluid (106) in the at least one measurement reservoir (104). The at least one measurement reservoir is adapted for varying the rate of change of an optical path length of the illumination beam in the fluid. The measurement reservoir properties are adapted for providing information of an optical path length of the illumination beam in the fluid at a plurality of moments during the filling with the fluid. Furthermore a corresponding optical characterisation device is described. The invention also relates to a corresponding method.Type: GrantFiled: July 20, 2007Date of Patent: November 22, 2011Assignee: Trinean NVInventors: Kris Naessens, Ronny Bockstaele, Bert Luyssaert, Roeland Baets

Patent number: 7864317Abstract: An optical characterisation system is described for characterising optical material. The system typically comprises a diffractive element (104), a detector (106) and an optical element (102). The optical element (102) thereby typically is adapted for receiving an illumination beam, which may be an illumination response of the material. The optical element (102) typically has a refractive surface for refractively collimating the illumination beam on the diffractive element (104) and a reflective surface for reflecting the diffracted illumination beam on the detector (106). The optical element (102) furthermore is adapted for cooperating with the diffractive element (104) and the detector (106) being positioned at a same side of the optical element (102) opposite to the receiving side for receiving the illumination beam.Type: GrantFiled: July 20, 2007Date of Patent: January 4, 2011Assignee: Trinean NVInventors: Ronny Bockstaele, Bert Luyssaert, Kris Naessens

Patent number: 7445390Abstract: A method is described for providing a predetermined optical path in an optical module, the predetermined optical path being defined by predetermined optical characteristics for the optical module. a modifiable optical element is provided at a predetermined position in the optical module, thus generating an initial optical path of the optical module. The modifiable optical element comprising at least one optical interface in the initial optical path. An optical signal is detected from a radiation beam on the initial optical path of the optical module. The optical interface of the modifiable optical element is then physically modified to generate at least one modified optical interface of the modifiable optical element. The physical modification takes into account the detected optical signal so as to obtain substantially the predetermined optical characteristics for the optical module.Type: GrantFiled: September 20, 2006Date of Patent: November 4, 2008Assignees: Interuniversitair Microelektronica Centrum (IMEC), Universiteit Gent (RUG)Inventors: Bert Luyssaert, Kris Naessens, Ronny Bockstaele
