  • Patent number: 10777909
    Abstract: Provided is a loop antenna array that can easily create a magnetic field distribution which enables the boundary of a communication area to be clearly set. 2n loop antennae are provided adjacently to one another, where n is a natural number. The directions of currents in adjacent ones of the loop antennae are opposite to each other. For example, in a loop antenna array, two loop antennae are disposed adjacently to each other on an insulator substrate. First feed points energize one loop antenna and second feed points energize the other loop antenna.

The method further includes receiving an input query that specifies a set of fragrance notes to be used to generate the new formulation. The method also includes choosing one of the input formulations which includes the set of fragrance notes to be used to generate the new formulation. The method additionally includes clustering the constituent topics of the chosen one of the input formulations based on a similarity metric. The method further includes generating the new formulation as a response to the input query by selecting, from the input formulations, materials for each of the clustered ones of the constituent topics.

The loop antenna includes a main loop 1 which is an open loop connected to a signal source 5 or a reception circuit; and an amplification loop 2 which is a closed loop having the same shape as the main loop 1. The main loop 1 and the amplification loop 2 are arranged on a same surface of a flat substrate formed of an insulator. A first capacitance is connected to the main loop 1, and a second capacitance is connected to the amplification loop.

  • Publication number: 20200113490
    Abstract: A measurement unit is attached to a measurement target person and measures an acceleration. A body motion calculation unit obtains the magnitude of a body motion of the measurement target person based on the acceleration measured by the measurement unit. An activity state determination unit time-serially obtains an activity state representing whether the measurement target person is in a first state or a second state, based on a posture decided by a posture decision unit and the magnitude of the body motion calculated by the body motion calculation unit. If the activity state after continues for a predetermined time defined in advance, an activity state correction unit determines that the transition of the activity state obtained by the activity state determination unit has been done. A time correction unit returns the transition time of the activity state determined by the activity state correction unit.

  • Patent number: 10454172
    Abstract: A main loop is an open loop that is wound on a bar-shaped rod formed of a magnetic body or an insulation body and that has terminals T and T that couple a signal source or a receiving circuit to the main loop. The number of turns is 1 or more. An amplifying loop is wound on a part of the rod that is different from the part on which the main loop is wound. The main loop and the amplifying loop are thus spaced from each other. The amplifying loop is a closed loop including no terminals. The number of turns is 1 or more. The number of turns may be the same as or different from the number of turns of the main loop.

  • Publication number: 20190188999
    Abstract: In a sensor relay apparatus (10), a communication control unit (13) receives sensor data from a sensor terminal (ST) via a terminal module (11) when a transmission data amount related to the sensor data to be transmitted from the sensor terminal (ST) is equal to or greater than a determination threshold. This can reduce the overhead time taken at the time of the transmission of the sensor data.

  • Patent number: 7606399
    Abstract: A sensor cell includes a sensor electrode (101) formed on a substrate (100), a signal output unit (16) which outputs a signal corresponding to a capacitance (Cf) formed between the sensor electrode and the surface of a finger (3), a high-sensitivity electrode (103) formed on the substrate so as to be insulated and isolated from the sensor electrode, and a potential controller (14) which controls the potential of the finger surface via a capacitance (Cc) formed between the high-sensitivity electrode and the finger surface by controlling the potential of the high-sensitivity electrode. In this arrangement, when the resistance of the finger is high, the potential of the finger surface can be controlled so as not to fluctuate with the potential change of the sensor electrode.
