Patent number: 10426360Abstract: A portable pulse measuring device having a lighting configuration having at least three elements selected from a light-emitting source for emitting radiant energy through a human body tissue and a light detector for detecting the intensity of said radiant energy after propagation through the human body tissue and for providing input signals representative of the propagation. The lighting configuration includes at least one light-emitting source and at least one light detector. A processor is provided for determining pulse rate in response to processing the input signals. The elements in the lighting configuration are arranged in the portable pulse measuring device in a configuration where the light-emitting sources in the lighting configuration are asymmetrically disposed in relation to the light detectors in the lighting configuration.Type: GrantFiled: May 15, 2014Date of Patent: October 1, 2019Assignee: PULSEON OYInventors: Jari Nousiainen, Ilkka Korhonen

Patent number: 8463370Abstract: The invention relates to a method for monitoring a condition of a patient under anesthesia or sedation, whereupon one, two, three or more signals are acquired, and the signal(s) represent(s) cardiovascular and/or combined electrical biopotential on skull activity of the patient. From said signal or signals are derived or calculated at least two parameter values related to a quantity like waveform amplitude, waveform periodicity, waveform morphology, waveform variability, energy, power, signal complexity and frequency content. A predetermined mathematical index for probability of patient comfort is used, in which function said parameters are variables, and successively changing probability index values of said mathematical index is calculated.Type: GrantFiled: March 20, 2008Date of Patent: June 11, 2013Assignee: Instrumentarium CorporationInventors: Ilkka Korhonen, Marcus Johannis Van Gils, Markku Paloheimo, Arvi Yli-Hankala, Matti Veli Tapani Huiku

Patent number: 7407486Abstract: The invention concerns a method and an apparatus for monitoring a condition of a patient under anesthesia or sedation. For this purpose there is a sensor for acquiring a signal that represents peripheral cardiovascular flow in the patient. Successive heart beat pulses are detected and predetermined pulse wave parameters are measured repeatedly in said signal, and predefined pulse wave parameters within said heart beat pulses are measured, too. At first, said predetermined pulse wave parameters in a number of successive heart beat pulses are compared in respect to possible occurrence of a substantial alteration. At second, if the alteration is noticed, a statistical reference value is calculated by deriving values from at least said predefined pulse wave parameters, and the change(s) between at least one predefined pulse wave parameter and said reference value is quantified. The results and/or intermediate results are finally displayed and/or recorded.Type: GrantFiled: October 14, 2002Date of Patent: August 5, 2008Assignee: GE Healthcare Finland OyInventors: Matti Veli Tapani Huiku, Ilkka Korhonen, Marcus Johannis Van Gils, Mikko Oskari Jousi, Jyrki Mika Petteri Lötjönen

Patent number: 4717957Abstract: The invention relates to a video compression method to be employed in connection with the conditional replenishment transmission and receiving method. In the transmitter there are detected such areas of the image that are changed with respect to the previous image, and the picture information representing the occurred changes, along with the addresses of the respective picture areas, is sent into the transmission channel. In the receiver there is reconstructed the new image on the basis of the previous image and the picture information representing the occurred changes.Type: GrantFiled: August 13, 1986Date of Patent: January 5, 1988Assignee: Valtion teknillinen tutkimuskeskusInventors: Harry Santamaki, Juha Leppanen, Pontti Haikonen, Ilkka Korhonen
