Patent number: 8834383Abstract: The invention concerns an apparatus, system, wearable apparatus and concomitant processing system to detect instants in time at which a cyclically pulsating object within the body of an individual is temporarily quiescent, such an object being the heart, an artery or the lungs. The essence of the invention is the use of a doppler radar motion sensor, normally used for vehicular speed detection or the detection of building occupancy. The doppler radar motion sensor is arranged to transmit electromagnetic signal towards the object and receive reflected electromagnetic signal from the object, and the apparatus is further arranged to identify the instants in time at which the reflected signal indicates the object is temporarily quiescent. The invention is particularly suitable for ambulatory monitoring of the heart.Type: GrantFiled: August 28, 2007Date of Patent: September 16, 2014Assignee: Koninklijke Philips N.V.Inventors: Jens Muehlsteff, Jeroen Adrianus Johannes Thijs, Robert Pinter

Patent number: 8559913Abstract: The invention relates to an emergency response system. The emergency response system (10) comprises a central station (4) for receiving information about emergencies, whereby position information of a victim is provided and stored in a look-up table (6) of the central station (4). The central station addresses a list (7) of publicly available actuatable emergency response devices and selects a suitable device. The central station (4) transmits a trigger signal by means of a suitable communication network (3) to the selected remote actuatable emergency response device (14), which comprises communication means (13) for activating the signaling means (15) upon receipt of the trigger signal. Also, the actuatable emergency response device (14) comprises storage means (11) arranged to store the position information of the emergency response device and the provided position information of the victim.Type: GrantFiled: December 16, 2004Date of Patent: October 15, 2013Assignee: Koninklijke Philips N.V.Inventors: Jeroen Adrianus Johannes Thijs, Guido Muesch, Jens Muehlsteff, Robert Pinter

Patent number: 8559589Abstract: The invention relates to a waveguide (24) for focusing electromagnetic energy on an area of interest, said waveguide (24) comprising outer walls forming a channel with a width (w) and a height (h) for the propagation of the electromagnetic waves. In order to be able to focus the EM waves on an area of interest, i.e. the chest of a patient (20), so that influences which other moving objects in the environment have on the waves, are shielded away, the channel is provided with a first opening and a second opening wherein said walls are non-metal hollow walls filled with an electrically conductive liquid. The waveguide (24) can be used for example with a computed tomography system (12) CT with a rotating gantry (16) and a patient table (18). The waveguide (24) will not produce artefacts in the CT image by scattering the X-ray, like a metal wall would do it. Nevertheless the conductive liquid makes the construction work as a waveguide for EM waves.Type: GrantFiled: March 12, 2009Date of Patent: October 15, 2013Assignee: Koninklijke Philips N.V.Inventors: Robert Pinter, Jens Muehlsteff, Jeroen Adrianus Johannes Thijs

Patent number: 8428699Abstract: An apparatus measures properties of an object such as a heart in a patient (2). The apparatus includes an antenna (3, 4) for sending and/or receiving electromagnetic waves to and/or from the object (2) for measuring a property of the object. The antenna (3, 4) includes an electrically conductive element for functioning as an electrode for measuring a further property of the object. The electromagnetic waves are reflected by the object, causing a Doppler shift. The apparatus uses this shift to provide mechanical information about the object and uses the electrode to provide electrical information about the object, such as an electrocardiogram.Type: GrantFiled: December 16, 2008Date of Patent: April 23, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Robert Pinter, Jeroen Adrianus Johannes Thijs, Jens Muehlsteff
