Patent number: 9644684Abstract: A bearing arrangement having a bearing mounted in a housing, wherein a grease lubricant is present within the housing for lubricating the bearing, a support frame at least partly made of an electrically insulating material, arranged in a space within the housing that lies axially between the bearing and a housing seal. The support frame includes at least one electrode pair having first and second electrodes arranged to enable grease lubricant to contact therewith. A capacitance meter provided for measuring a capacitance between the first and second electrodes. The support frame provides a radially oriented surface and a plurality of ribs that extend in a radially inward direction, the ribs having sufficient circumferential spacing to enable grease to flow between adjacent ribs. One of the first and second electrodes is provided on the radially oriented surface of the support frame or on a rib surface that faces an adjacent rib.Type: GrantFiled: March 28, 2016Date of Patent: May 9, 2017Assignee: AKTIEBOLAGET SKFInventors: Jeroen Bongaerts, Florin Tatar

Patent number: 9631971Abstract: A photoacoustic probe and photoacoustic device implementing the photoacoustic probe may reduce an artifact caused by an ultrasonic wave generated in the photoacoustic probe without mounting a separate device. The photoacoustic probe and photoacoustic device implementing the photoacoustic probe may reduce an artifact by changing a configuration or a structure provided in the photoacoustic probe. The photoacoustic probe may receive a photoacoustic signal generated from an inner material of an object absorbing light of a predetermined wavelength and may include a piezoelectric module to convert the photoacoustic signal into an electric signal, and an object contact unit disposed on the front surface of the piezoelectric module, the object contact unit contacting the object and not absorbing the light of a predetermined wavelength.Type: GrantFiled: December 27, 2013Date of Patent: April 25, 2017Assignees: SAMSUNG MEDISON CO., LTD., SAMSUNG ELECTRONICS CO., LTD.Inventors: Jung Taek Oh, Jung Ho Kim, Jong Kyu Jung

Patent number: 9556913Abstract: A bearing arrangement is provided having a bearing mounted in a housing, wherein a grease lubricant is present within the housing for lubricating the bearing. The arrangement further provides a support frame made of an electrically insulating material, arranged in a space within the housing between the bearing and a housing seal. The support frame is provided with at least one electrode pair having first and second electrodes arranged such that a portion of the grease lubricant is located between the first and second electrodes. A capacitance meter is provided for measuring a capacitance between the first and second electrodes. The first and second electrodes of the at least one electrode pair are provided on a radially oriented surface of the support frame, which surface is arranged such that the grease is able to move in an axial direction over the surface.Type: GrantFiled: March 28, 2016Date of Patent: January 31, 2017Assignee: AKTIEBOLAGET SKFInventors: Jeroen Bongaerts, Florin Tatar

Patent number: 9459202Abstract: A collision-computing system detects and amplifies the energy associated with a feature signal to determine occurrences or absence of events, such as ultrasonic and/or geophysical events, or to determine presence and/or concentrations of substances such as blood glucose, toxic chemicals, etc., in a noisy, high-clutter environment or sample. To this end, a conditioned feature, obtained by modulating a carrier kernel with a feature signal, is collided with a Zyoton—a waveform that without a collision can travel substantially unperturbed in a propagation medium over a specified distance. The conditioned feature and the Zyoton are particularly constructed to be co-dependent in terms of their respective dispersion velocities and the divergence of a waveform resulting from the collision. The collision operation can transfer at least a portion of the feature energy to the resulting waveform, and the transferred energy can be amplified in successive collisions for detecting/measuring events/substances.Type: GrantFiled: January 12, 2016Date of Patent: October 4, 2016Assignee: Zyomed Corp.Inventors: Sandeep Gulati, Timothy L. Ruchti, William Van Antwerp, John L. Smith
