  • Patent number: 10187470
    Abstract: The data acquisition unit acquires sensor data according to an acquisition rule stored in the acquisition and processing rule DB. Then the data acquisition unit determines a representative value for each predetermined time interval on acquired data according to the buffer setting information stored in the buffer setting information DB and saves at least a predetermined number of representative values in the buffer provided in the main memory. The processing unit processes the predetermined number of representative values saved in the buffer to determine the processed data according to a processing rule stored in the acquisition and processing rule DB. The data upload unit transmits to the M2M server the processed data determined by the processing unit.

  • Patent number: 10003277
    Abstract: A power converter including a compressor as a load includes a compensation current output (80) allowing compensation current (Ic), which compensates for leakage current (Ia), to flow. A controller (50) receives a detection signal from a rotational speed sensor (55) which senses the rotational speed of the compressor (CM). When the rotational speed has increased to a set rotational speed at which the leakage current (Ia) is lower than or equal to its limiting value (Lmax) (e.g., the limiting value specified under the Electrical Appliances and Materials Safety Act or by the IEC) in a state where the compensation current output (80) is off, the compensation current output (80) is switched from an on state to an off state. This may reduce the leakage current from the compressor with low power loss.

  • Patent number: 9470444
    Abstract: An indoor-unit transmission/reception unit and an outdoor-unit transmission/reception unit are connected via a first signal line, and another indoor-unit transmission/reception unit and another outdoor-unit transmission/reception unit are connected via a second signal line. A first return switch is connected between a first power supply line and the first signal line, and a second return switch is connected between the first power supply line and the second signal line. A first end of a second switch is connected to the first power supply line, and a second end of the second switch is connected to the cathodes of two diodes. The anodes of the first and the second diodes are connected to the first and the second signal lines, respectively. A common end of the second switch is connected to the first end or the second end thereof. An outdoor-power supply unit is fed with electric power from the common end of the second switch and the second power supply line.

  • Publication number: 20160142493
    Abstract: The sensor data collection system includes one or a plurality of sensors; a gateway device capable of collecting, converting, processing, making a threshold determination of, and compressing data from the sensors and transmitting the data to a data collection server at a timing set as needed; and the data collection server that collects the sensor data from the gateway device. The data collection server includes a means that compresses sensor data conversion, processing, threshold determination, compression, and transmission timing settings into a binary and transmits the binary to the gateway device. The gateway device includes a means that executes conversion, processing, threshold determination, and compression with respect to the data collected from the sensors in accordance with the various settings compressed into the binary, and that transmits the sensor data to the data collection server at the set transmission timing.

  • Publication number: 20070037882
    Abstract: In accordance with the invention, a compound with a protective action for nerve cell can be reselected by adding PPAR? agonist to a culture cell system where toxic substances such as thapsigargin, MPP+ and staurosporine are preliminarily allowed to react and reselecting a compound improving the survival rate. The compound selected by such method can be used as an active ingredient of a therapeutic agent for neurodegenerative diseases such as cerebral infarction and Parkinson's disease. Thus, the invention is very useful for research works for creating novel pharmaceutical agent.

  • Patent number: 5295149
    Abstract: A gas laser device, including an a.c. power source for generating a.c. output voltage and a pair of electrodes positioned sandwiching discharge gap through which laser gas circulates. The pair of electrodes are connected to the a.c. power source for applying the a.c. voltage across the electrodes to achieve discharge in the discharge gap such as to create a positive column region and boundary layer regions, thereby to generate laser light. The positive column region is created in the discharge gap and a.c. power injected therein contributes to laser excitation. The boundary layer regions is created in a vicinity of one of the pair of electrodes, respectively and a.c. power injected therein does not contribute to laser excitation. A frequency of the a.c. power source is set to at least 700 kHz and an a.c. output voltage of the a.c. power source is set at a level such that a voltage in the positive column region is larger than a burden voltage in the boundary layer regions.
