20090054116 | Method and apparatus for scent dispensing - A scent dispenser is integratable into a portable device, such as a mobile handset. The scent dispenser has a vibrating element configured to vibrate in an ultrasound frequency range for dispensing a scent material. Scent dispensing can be in response to an incoming signal received by a mobile handset, but scent dispensing can also be controlled by a user. The scent material is stored in a compartment having a channel with a valve and the vibrating element can be used to open the valve for replenishing the scent material when the vibration is in a low frequency range such as 1-10 Hz. The vibrating element can also be used to produce audio signals. Thus, the scent dispenser can also be integrated with a sound producing unit in a mobile electronic device. | 02-26-2009 |
20100162527 | Method and apparatus for a hinge - In accordance with an example embodiment of the present invention, there is provided an apparatus including a first body, a second body, and a joint member, the joint member having supported therein a first shaft and a second shaft, the first shaft connected to the first body and the second shaft connected to the second body, wherein the joint member is configured to cause or to allow a change in a separation distance between the first shaft and the second shaft upon a rotational movement of the first body relative to the second body. | 07-01-2010 |

20080294386 | Method and Device For Interference Suppression in Electromagnetic Multi-Channel Measurement - The present invention recognises and eliminates from a biomagnetic measurement signal interferences whose source is disposed in the direct vicinity of an object being measured. The invention utilises the SSS method that can be used to separate from one another the signals associated with the internal and external sources of a set of measurement sensors by calculating two series developments. The sources to be examined in the invention and disposed in the so-called intermediate space produce a component to both of the developments, and can, therefore, be detected by means of an analysis to be performed in a time domain. This division into components can be made using the Principal Component Analysis (PCA), the Independent Component Analysis (ICA) or the Singular Value Decomposition. Finally, the clarified interferences in the intermediate space can be eliminated from the measured signal using, for example, the linear algebraic orthogonal projection. | 11-27-2008 |
20090069661 | METHOD FOR SEPARATING MULTICHANNEL SIGNALS PRODUCED BY AC AND DC SOURCES FROM ONE ANOTHER - The present invention relates to a novel manner of measuring DC fields using a multi-channel MEG or MKG measuring instrument; and on the other hand, to a manner of eliminating from the measurement result the interference signals caused by the DC currents. The invention combines the monitoring system of a testee's movement and the method for motion correction of the measured signals so that the signals produced by the DC currents of a moving testee's are visible in the final measurement result as a static signal component in a conventional MEG or MKG measurement. In that case, in the measurement, it is not necessary to beforehand prepare oneself for measuring the DC fields. | 03-12-2009 |
20090184709 | Method for Interference Suppression in a Measuring Device - The present invention describes a method enabling one to shield a device that measures weak biomagnetic signals from strong magnetic interference fields. The measurement sensors are provided with a feedback compensation loop, the difference signal of which is obtained from the measurement sensors themselves. As the actuator of the feedback function, one or more coils are responsible for eliminating, the external interference fields in the region of the sensors. Difference signals can be generated as a linear combination from the signals of two or more sensors. In the control logic, the SSS method can be used to numerically separate the biomagnetic signal being measured from the signals produced by the sources—compensation coils and interference sources—disposed outside the measurement region. The interference suppression can be enhanced by placing the assembly of sensors and the actuators within a magnetically shielding room. | 07-23-2009 |

20140343882 | METHOD AND DEVICE FOR RECOGNIZING AND REMOVING UNDESIRED ARTIFACTS IN MULTICHANNEL MAGNETIC FIELD OR ELECTRIC POTENTIAL MEASUREMENTS - The present invention introduces a method, device and a computer program for removing artifacts present in individual channels of a multichannel measurement device. At first, a basis is generated defining an n-dimensional subspace of the N-dimensional signal space, where n is smaller than N, where using in the definition of the n-dimensional basis a physical model of a Signal Space Separation method, or a statistical model based on the statistics of recorded N-dimensional signals. Thereafter, a combined (n+m)-dimensional basis is formed by adding m signal vectors to the n-dimensional basis, each of these m signal vectors representing a signal present only in a single channel of the N-channel device. After this the recorded N-dimensional signal vector is decomposed into n+m components in the combined basis, and finally, components corresponding to the m added vectors in the combined basis are subtracted from the recorded N-dimensional signal vector. | 11-20-2014 |
