Patent number: 11933892Abstract: An ultrasound imaging system has an array of ultrasound transducers comprising a set of sub-arrays of transducers. Each transducer (100) has an analogue buffer (106). Each sub-array of transducers has a signal path (102, 104) from within the array of ultrasound transducers to outside the array of ultrasound transducers which comprises one or more hops between the buffers (106). To reduce the signal line length from inside the array of ultrasound transducers to the periphery, at least some multiple hops between buffers (106) are provided. Each buffer hop introduces a delay, but prevents signal degradation so that a large number of analog signals can be transmitted across the large area ASIC of the transducer array.Type: GrantFiled: January 20, 2017Date of Patent: March 19, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: David Andrew Fish, Gerardus Johannus Jacobus Maria Arnoldussen, Sotir Filipov Ouzounov, Emil Dimitrov Totev

Patent number: 11139426Abstract: An active matrix array of electroactive polymer actuators is provided, each electroactive polymer actuator having a switching arrangement. The switching arrangement comprises a first circuit (90) connected to a first terminal of the electroactive polymer actuator, for selectively driving the first terminal of the electroactive polymer actuator to ground or connecting it to an open circuit. A second circuit (92) is connected to a second terminal of the electroactive polymer actuator, for selectively driving the second terminal of the electroactive polymer actuator to ground or connecting it to an open circuit. Furthermore, a pull-up component (50) is permanently connected between a drive voltage and the first terminal of the electroactive polymer generator. By controlling both terminals of the electroactive polymer actuator, it is possible to reduce static power consumption, at least when no voltage is to be stored across the electroactive polymer actuator.Type: GrantFiled: December 9, 2016Date of Patent: October 5, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Mark Thomas Johnson, David Andrew Fish

Patent number: 11139425Abstract: An active matrix array of electroactive polymer actuators (36) is provided, each electroactive polymer actuator (36) having a switching arrangement (34). The switching arrangement comprises an input which is connected to a respective data line (30) and an output which is connected to a first terminal of the associated electroactive polymer actuator (36), wherein a second terminal of each electroactive polymer actuator is connected to a control line (110).

Patent number: 10711769Abstract: An actuator device comprises an active matrix array of rows and columns of electroactive polymer actuators, each electroactive polymer actuator having a switching circuit. The switching circuit has a drive transistor and a capacitor arrangement. The capacitor arrangement is charged to a voltage derived from a drive voltage for the electroactive polymer actuator combined with a voltage derived from the drive transistor threshold voltage. During this programming of the capacitor arrangement, the EAP actuator is isolated from any current flowing. The switching circuit enables compensation for age-related changes in the threshold voltage. Thus, a low performance (i.e. with poor threshold voltage stability) transistor may be used, with measurement of the threshold voltage of the current-providing TFT once per frame time (or once per multiple frame times) to compensate for the aging effect.Type: GrantFiled: September 22, 2017Date of Patent: July 14, 2020Assignee: Koninklijke Philips N.V.Inventors: Mark Thomas Johnson, David Andrew Fish
