  • Patent number: 11744469
    Abstract: In order to enable the measurement of thermal property information about a subject, this thermal diffusion coefficient measuring device, which is used by contacting the surface of a living body, is provided with: a biological information sensor comprising a temperature sensor and a heat flux sensor; and a heating/cooling control means. The temperature sensor is provided at a position contacting the surface of the living body, and operates so as to detect skin temperature. The heat flux sensor is provided at a position contacting the surface of the living body, while being adjacent to the temperature sensor, and operates so as to detect heat flux on the surface of the living body. The heating/cooling control means enables the measurement of the temperature diffusion coefficient of a thermal resistance component that is present between the biological information sensor and a deep inner portion of the living body.

  • Patent number: 11105376
    Abstract: In order to determine information about the generation of heat in a bearing (10) in a simple manner, a bearing (10) includes an outer ring (12) secured to a securing member, and an inner ring (11) provided on the inside of the outer ring (12) and secured to a shaft that rotates in the circumferential direction relative to the securing member. A thermal flow sensor (14) is provided as a coating on a securing-side surface that includes the outer ring (12), and generates a thermoelectromotive force including information about frictional heat generated with the rotation of the shaft.

  • Publication number: 20200042580
    Abstract: The invention enhances a user's ability to locate pertinent information in a sea of less relevant information. The invention enhances known artificial intelligence techniques by allowing a user to characterize select portions of information through a user interface which mimics manual workflows but has the added value of learning from those actions to improves system-wide performance.

  • Patent number: 7062027
    Abstract: An SCP is provided with a pattern notifying unit. The pattern notifying unit is configured so that, on the occasion of providing a service utilizing ISUP interwork between a first leg defined between an originating switching center and a forwarding MSC and a second leg defined between forwarding MSC and a receiving MSC, it notifies the forwarding MSC of an interwork pattern number corresponding to a category of the service. The forwarding MSC according to the present invention performs processes such as “abandon and then generate” and “transmit” to parameters with reference to an interwork pattern corresponding to the interwork pattern number provided.

  • Patent number: 6626268
    Abstract: In an opening and closing apparatus for an elevator door, a light-emitter and a light-detector are disposed in safety shoes disposed on doorstop edges of each of two abutting elevator doors. The light-emitter emits a reflection detection beam toward a landing side obliquely, relative to an opening and closing direction of the elevator doors. The reflection detection beam reflected by an obstruction on the landing enters the light-detector. When the reflection detection beam enters the light-detector, a reflection detection signal is output by a reflection detector portion and the direction of operation of the elevator doors is reversed to an opening direction.
