Patent number: 11877786Abstract: An energy application apparatus applies energy to an object. An energy application unit applies energy to the object, wherein the energy application unit is adapted to use electrical current for applying the energy. A current measuring unit measures the electrical current used by the energy application unit and provides a signal being indicative of whether the energy is applied to the object based on the measured electrical current. The signal can be used by, for instance, a monitoring unit and/or a display unit for using and/or indicating the information whether energy is actually applied or not, without requiring a direct communication between the energy application unit and the monitoring unit and/or the display unit.Type: GrantFiled: December 18, 2020Date of Patent: January 23, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Franciscus Paulus Maria Budzelaar, Godefridus Antonius Harks, Steven Antonie Willem Fokkenrood

Patent number: 10226226Abstract: The invention relates to a filtering apparatus (15) for filtering an ultrasound signal, which is influenced by an electrical unit and comprises a first part including information about an object (4) from which the ultrasound signal has been received and a second part not comprising information about the object. A correction signal determination unit (17) determines a correction signal being indicative of the influence of the electrical unit on the ultrasound signal from the second part of the ultrasound signal and a correction unit (18) corrects the first part of the ultrasound signal based on the determined correction signal for filtering the influence of the electrical unit out of the ultrasound signal. Since the correction signal is indicative of the influence of the electrical unit, wherein the correction signal is used for correcting the ultrasound signal, unwanted interference visible in the unfiltered ultrasound signal can be filtered out.Type: GrantFiled: November 14, 2011Date of Patent: March 12, 2019Assignee: Koninklijke Philips N.V.Inventors: Steven Antonie Willem Fokkenrood, Franciscus Paulus Maria Budzelaar, Nanad Mihajlovic, Erik Godefridus Antonius Harks, Szabolcs Deladi

Patent number: 10188458Abstract: The invention relates to an inductive disturbance reduction device (18) for reducing an inductive disturbance of a signal like an ultrasound signal to be transmitted via first connection conductors (25, 26) of an electrical connector (11), which is caused when ablation current flows through a second connection conductor (24) of the electrical connector. The inductive disturbance reduction device is adapted to induce a voltage, which at least partly compensates a voltage induced in the electrical connector, in order to reduce the inductive disturbance in the signals to be transmitted via the first connection conductors of the electrical connector. Since the inductive disturbance is reduced, a high quality electrical connection can be provided, without necessarily using, for instance, a technically relatively complex and expensive coaxial connector. The inductive disturbance reduction device may be integrated, for instance, in a part of the electrical connector or in a cable.Type: GrantFiled: April 24, 2014Date of Patent: January 29, 2019Assignee: Koninklijke Philips N.V.Inventors: Franciscus Paulus Maria Budzelaar, Szabolcs Deladi

Patent number: 9669208Abstract: The present invention regards a probe for deep brain stimulation (DBS), with high overall impedance, but low overall resistance. This is achieved since the probe comprises a structure comprising at least two interconnected spirals, wherein said two spirals have different direction of rotation. A system for deep brain stimulation comprising the probe, a power source and an electrode is also disclosed.Type: GrantFiled: November 9, 2009Date of Patent: June 6, 2017Assignee: Medtronic Bakken Research Center B.V.Inventors: Dirk Willem Harberts, Ke Wang, Franciscus Paulus Maria Budzelaar, Hubert Cecile Francois Martens

Patent number: 9662170Abstract: The invention relates to a sensing apparatus for sensing an object. The sensing apparatus comprises an ultrasound unit (11) for ultrasonically sensing the object (4), an electrical energy application unit (9) for applying electrical energy to the object (4), and an ultrasound unit shielding element (16) for electrically shielding the ultrasound unit (11), wherein the ultrasound unit shielding element (16) is electrically connected to the electrical energy application unit (9). Since the ultrasound unit shielding element electrically shields the ultrasound unit, the ultrasound sensing of the object is less influenced by a capacitive coupling of the application of electrical energy, in particular, of an RF signal which may be used for applying the electrical energy, into the ultrasound sensing. A further reduction of this influence is achieved by electrically connecting the ultrasound unit shielding element to the electrical energy application unit.Type: GrantFiled: November 3, 2011Date of Patent: May 30, 2017Assignee: Koninklijke Philips N.V.Inventors: Franciscus Paulus Maria Budzelaar, Nenad Mihajlovic, Antonius Johannes Josephus Rademakers, Cornelius Antonius Nicholaas Maria Van Der Vleuten

The cell comprises a first storage electrode (24), a second storage electrode (22), a first target area electrode (28), a second target area electrode (30), a first type of particle (32) and a second type of particles (33), said second type of particles being of opposite polarity to the first type of particles. An area (31) extending between the target area electrodes (28, 30) is a target area. The method comprises a reset phase (110), wherein said first and second type of particle are reset to determined reset positions, a first write phase (120), wherein the first type of particles are moved to and/or from the storage electrodes and change in amount in said target area (31), a second write phase (140) similar to the first write phase but for the second type of particles, and a spread phase (150) so that the particles in said target area (31) distribute and mix.Type: GrantFiled: November 27, 2007Date of Patent: April 25, 2017Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Martinus Hermanus Wilhelmus Maria Van Delden, Sander Jurgen Roosendaal, Patrick John Baesjou, Alwin Rogier Martijn Verschueren, Franciscus Paulus Maria Budzelaar

Patent number: 9421359Abstract: The invention relates to a probe for an implantable electro-stimulation device. The probe (20) has a distal end (12) and a proximal end (13), and moreover comprises: one or more electrodes (11) a shield (21) of conducting material covering a major part of the probe, said shield extending from the vicinity of at least one of the one or more electrodes (11) towards the proximal end (13) or towards the distal end (12) of the probe (20); and a layer (22a, 22b) of insulating material covering part of the shield (21) in the vicinity of the at least one of the one or more electrodes. The shield protects wires (14), extending from electrodes to the proximal end of the probe, from undesired interference of external RF fields. The exposed part of the shield not covered by the layer of insulating material serves as a return electrode for the electrostimulation signal path.Type: GrantFiled: October 7, 2009Date of Patent: August 23, 2016Assignee: MEDTRONIC BAKKEN RESEARCH CENTER B.V.Inventors: Ke Wang, Hubert Cecile Francois Martens, Franciscus Paulus Maria Budzelaar, Dirk Willem Harberts, Michael Marcel Jose Decre, Jeroen Jacob Arnold Tol
