Patent number: 9778470Abstract: A multi-view display is switchable between single view and multi-view modes, and uses lenticular arrangement over a display panel which includes birefringent electro-optic material adjacent to a non-switchable optically transparent layer. The non-switchable optically transparent layer has a refractive index substantially equal to the extra ordinary refractive index of the birefringent electro-optic material. In the single view mode, the birefringent electro-optic material defines a non-switched state, and the polarization of the light from the display panel and incident on the lenticular arrangement is linear and aligned with the optical axis of the birefringent electro-optic material at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.Type: GrantFiled: September 19, 2011Date of Patent: October 3, 2017Assignee: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Fetze Pijlman, Jan Van Der Horst

Patent number: 9730677Abstract: A matrix array ultrasound probe passively dissipates heat developed by the matrix array transducer and beamformer ASIC away from the distal end of the probe. The heat developed in the transducer stack is coupled to a metallic frame inside the handle of probe. A metallic heatspreader is thermally coupled to the probe frame to convey heat away from the frame. The heatspreader surrounds the inside of the probe handle and has an outer surface which is thermally coupled to the inner surface of the probe housing. Heat is thereby coupled evenly from the heatspreader into the housing without the development of hotspots in the housing which could be uncomfortable to the hand of the sonographer.Type: GrantFiled: May 11, 2012Date of Patent: August 15, 2017Assignee: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Richard Edward Davidsen, Steven Russell Freeman, Bernard Joseph Savord

Patent number: 9702969Abstract: An ultrasonic diagnostic imaging system produces audio Doppler from detected Doppler signals. The Doppler signals are detected in a band of frequencies which corresponds to the velocity of blood flow signals, and Doppler information is displayed based on the detected band of frequencies. The audio Doppler system produces Doppler audio in a frequency band which is shifted in pitch from the detected band of frequencies. The operator of the ultrasound system is provided with a user control by which the degree of pitch shifting can be controlled. The ultrasound system displays Doppler blood flow velocities referenced to a transmit Doppler frequency f0, with the audio Doppler being shifted in pitch from the frequencies corresponding to the blood flow velocities.Type: GrantFiled: April 19, 2010Date of Patent: July 11, 2017Assignee: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: David Hope Simpson, David Clark, Anup Agarwal

Patent number: 9689941Abstract: Coil elements (18) generate a B1 excitation field in an examination region (14), which B1 excitation field is distorted by patient loading (e.g., wavelength effects). Passive shimming elements (22, 24) are disposed between the coil elements and the subject in order to improve the B1 field uniformity. In one embodiment, passive shimming elements include one or more dielectric rods (55) disposed below the subject which generate no substantial MR proton signal and which have a permittivity of at least 100 and preferably greater than 500. In another embodiment, tubes (24) adjacent each coil element are supplied with a dielectric liquid, a thickness of the dielectric liquid between the coil element and the subject adjusting a phase of the B1 field generated by the coil element. Active B1 shimming may be combined with passive shimming elements (22, 24) to effect an improved RF field homogeneity result.Type: GrantFiled: December 5, 2011Date of Patent: June 27, 2017Assignee: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Zhiyong Zhai, Michael Andrew Morich, Paul Royston Harvey, Miha Fuderer

Patent number: 9677873Abstract: An apparatus, method and computer program for measuring a distance using a self-mixing interference (SMI) unit that generates an SMI signal. The SMI unit comprises a laser emitting a first laser beam directed to an object and wherein the SMI signal depends on an interference of the first laser beam and a second laser beam reflected by the object. A peak width determination unit determines a peak width of the SMI signal, and a distance determination unit determines a distance between the object and the SMI unit depending on the determined peak width of the SMI signal. Since the distance is determined depending on the peak width of the SMI signal, without requiring a laser driving current modulation, advanced electronics for modulating the driving current of the laser are not needed. This reduces the technical efforts needed for determining the distance.Type: GrantFiled: July 19, 2011Date of Patent: June 13, 2017Assignee: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Alexander Marc Van Der Lee, Mark Carpaij

Patent number: 9541618Abstract: A state space feedback controller operates in the digital domain for the regulation of the current supply to MRI gradient coils from a multiple-bridge PWM power amplifier. The P1-controller includes an integration part (for the integration of the difference between the demand current and the measured gradient coil current) and a subsequent P-controlled system which in turn includes a delay compensator/stabilizer and a plant. The delay compensator/stabilizer includes a multi-path feedback loop by means of which its digital output signal is fed back through delay blocks, on the one hand, and through filter units, on the other hand. The filter units model the transfer functions of a gradient coil output filter for the gradient coil voltage and the output current of the amplifier inverter units, respectively. In the plant, a filter unit, which models the gradient coil transfer function, is connected in series to a delay chain for the delay of the measurement value of the gradient coil current.Type: GrantFiled: December 15, 2011Date of Patent: January 10, 2017Assignee: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Thomas Scheel, Christian Hattrup
