Patent number: 9811212Abstract: Ultrasound is used to detect the proximity of an object and whether the object touches a body of an electronic device. A transducer may produce ultrasonic waves to air and to the device body simultaneously. The transducer is connected to the body, allowing a vibration of the ultrasonic waves to travel in the body. The vibration characteristics, for example the decay, change in the body when the body is touched. The decay may be analyzed to detect the touch. The transducer produces the ultrasonic waves to the airspace in proximity to the electronic device. Waves returning from the airspace, for example, after reflecting back from a proximate object, are analyzed and proximity or a gesture of the object may be detected.Type: GrantFiled: February 25, 2015Date of Patent: November 7, 2017Assignee: Microsoft Technology Licensing, LLCInventor: Petri Jarske

Patent number: 9720546Abstract: A force sensitive surface measures force or pressure applied to the surface. The surface may also detect the touch position. The force sensing surface is calibrated with a stylus having a force measuring element. The stylus measures the force information from force applied on the surface and sends the information to the device with the force sensing surface. The device detects the same force and calibrates the force sensing element according to the information received from the stylus. The device may also detect the position of the touch. As the force information obtained from different portions of the surface may be different, the calibration may be repeated for multiple positions on the force and touch sensitive surface. The calibration may also be used to calibrate a position sensing feature on a force sensing surface having multiple force sensors.Type: GrantFiled: September 15, 2015Date of Patent: August 1, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Lauri Jääskelä, Henri Autio, Pasi Kemppinen, Petri Jarske, Matti Pellikka

Patent number: 7724885Abstract: A method for distinguishing speakers in a conference call of a plurality of participants, in which method speech frames of the conference call are received in a receiving unit, which speech frames include encoded speech parameters. At least one parameter of the received speech frames is examined in an audio codec of the receiving unit, and the speech frames are classified to belong to one of the participants, the classification being carried out according to differences in the examined at least one speech parameter. These functions may be carried out in a speaker identification block, which is applicable in various positions of a teleconferencing processing chain. Finally, a spatialization effect is created in a terminal reproducing the audio signal according to notified differences by placing the participants at distinct positions in an acoustical space of the audio signal.Type: GrantFiled: July 11, 2005Date of Patent: May 25, 2010Assignee: Nokia CorporationInventors: Petri Jarske, Jussi Virolainen

Patent number: 7321911Abstract: Methods, devices and a software product for generating a sinusoidal signal of a desired frequency at a desired sampling rate. If the frequency is higher than the upper limit, a coefficient is determined as a function of the sampling rate and a sample of the first output sample sequence is determined as a linear combination of the coefficient and two previous output samples. The first output sample sequence is decimated by the sampling rate. If the frequency is lower than the lower limit, the coefficient is determined as a function of the sampling rate and the sample of the first output sample sequence is determined as a linear combination of the coefficient and two previous output samples. The first output sample sequence is multiplied so as to generate a second output sample sequence. The second output sample sequence is decimated by the sampling rate.Type: GrantFiled: March 11, 2004Date of Patent: January 22, 2008Assignee: Nokia CorporationInventor: Petri Jarske

Publication number: 20030198258Abstract: The present invention relates to a method for determining the propagation delay of a signal. In the method a burst signal transmitted from one or more access points is received, said signal comprising at least one part containing fixed information. Samples are taken from the received signal to produce a sampled signal (s(n)). The received signal comprises signal components propagated via one or several paths. In the method the sampled signal (s(n)) and the signal corresponding to said fixed information (t(n)) are correlated with each other, wherein the correlation results produced in the correlation are processed by separating at least one signal component from the correlation results. Said signal corresponding to said fixed information (t(n)) is used in the separation.Type: ApplicationFiled: March 7, 2003Publication date: October 23, 2003Applicant: Nokia CorporationInventor: Petri Jarske

Patent number: 6198358Abstract: An oscillator circuit comprises two main transistors (Q1, Q2), between which is provided a positive feedback by connecting each transistor base to the collector of the other transistor via buffer transistors (Q3, Q4). A capacitor (C) is connected between the emitters of the main transistors. The frequency of the oscillator is controlled by two current sources (11, 12), which control the current (I2, I2) flowing through the capacitor (C). Additionally, a compensation current (Icom) is conducted via collector resistors (Rc1, Rc2) of the main transistors such that the current flowing through each resistor is essentially constant and independent of the control current (I1, I2), so the signal amplitude of the oscillator does not change during frequency control.Type: GrantFiled: May 18, 1998Date of Patent: March 6, 2001Inventors: Nikolay Tchamov, Petri Jarske
