  • Patent number: 10842585
    Abstract: A model of a body part, e.g., liver, of which the internal structure can be observed easily; and others. In a liver model according to the present invention, the liver parenchyma is formed in the form of a frame to make it possible to observe the portal, veins, a tumor and others in the inside of the frame 31a easily. In addition, the liver model can be handled easily by gripping a gripping part provided at the lower end surface of the inferior vena cava, and the tumor is integrated with the liver model by means of a joint part. The liver model can be manufactured from a model material using a 3D printer on the basis of three-dimensional shape data for model manufacturing purposes, which are produced using an information processing device.

  • Publication number: 20200225349
    Abstract: A lidar 1 is provided with: a scanner 55 which emits an outgoing light Lo; a dark reference reflective member 7 which is arranged in a predetermined emitting direction and which absorbs the outgoing light Lo; an APD 41 which receives the return light Lr that is the outgoing light Lo reflected by an object; and a DSP 16. The DSP 16 estimates at least a receiver noise on the basis of the output signal of the APD 41 in the dark reference period Td when the dark reference reflective member 7 is irradiated with the outgoing light Lo. Then, on the basis of the estimated receiver noise, the DSP 16 applies a filtering to the output signal of the APD 41.

  • Publication number: 20200150236
    Abstract: A lidar 1 is provided with an APD 41 and a DSP 16. The APD 41 receives a return light Lr that is an outgoing light Lo radiated by a scanner 55 and thereafter reflected by an object. The DSP 16 includes a shot noise estimation unit 77 and a voltage control unit 78. The shot noise estimation unit 77 estimates, on the basis of the output signal from the APD 41, information associated with background light amount that is the sun light reflected by the object and thereafter received by the APD 41. The voltage control unit 78 determines, on the basis of the information associated with the estimated background light amount, the voltage to be applied to the APD 41 in order to control the gain M of the APD 41.

  • Patent number: 10544777
    Abstract: A method of controlling a floating-body wind turbine power generating apparatus including a wind turbine generator disposed on a floating body includes a pitch-angle increasing step of increasing a pitch angle of a blade of the wind turbine generator when the wind turbine generator is stopped, so that an aerodynamic braking force is applied to a rotor of the wind turbine generator. In the pitch-angle increasing step, a first change rate of the pitch angle of the blade in a first period during which the wind turbine generator is in an inclining motion toward an upwind side from a vertical direction due to sway of the floating body, is smaller than a second change rate of the pitch angle of the blade in a second period during which the wind turbine generator is in an inclining motion toward a downwind side from the vertical direction due to the sway of the floating body.

  • Publication number: 20190250250
    Abstract: A LIDAR 1 includes: a scanner 55 that emits outgoing light Lo while changing the outgoing direction thereof; a reflection member 8 that is arranged in a first outgoing direction and reflects the outgoing light Lo; an absorption member 7 that is arranged in a second outgoing direction and absorbs the outgoing light Lo; an APD 41 that receives return light Lr; and a DSP16. The DSP 16 generates replica u representing a component reflected by the absorption member 7 on the basis of output signals of the APD 41 obtained at each time when the outgoing light Lo is emitted in the first outgoing direction and in the second outgoing direction.

  • Publication number: 20190049582
    Abstract: On the basis of a segment signal Sseg outputted by a core unit 1, a signal processing unit 2 of a LIDAR unit 100 generates a polar coordinate space frame Fp indicating the received light intensity of laser light with respect to each scan angle that indicates the outgoing direction of the laser light and its corresponding target distance Ltag. Then, the signal processing unit 2 converts the polar coordinate space frames Fp into an orthogonal coordinate space frame Fo and outputs it to a display control unit 3. Further, for an outgoing direction of the laser light in which the segment signal Sseg outputted by the core unit 1 indicates a received light intensity equal to or larger than a threshold Apth, the signal processing unit 2 generates the measurement point information Ip and outputs it to a point group processing unit 5.

  • Patent number: 9628372
    Abstract: A data communication apparatus forms a mesh network together with at least one gateway includes a frame generating unit and a frame transferring unit. The frame generating unit generates a meter data frame to transmit to a gateway. The meter data frame is a frame including meter data. The frame transferring unit transfers the meter data frame received from another data communication apparatus. The meter data frame is addressed to the gateway. The frame generating unit transmits the meter data frame to which number of alternate routing that indicates number of allowable transmission attempts from a data communication apparatus adjacent to a destination gateway of the meter data frame to the gateway is added. The frame transferring unit changes the number of alternate routing added thereto to a value smaller by 1 than a value that has been set and transits the meter data frame to another data communication apparatus.

  • Patent number: 9521075
    Abstract: A communication device is included in an ad hoc network in a reactive routing scheme. The communication device includes a receiving unit, a selecting unit, and a transfer control unit. The receiving unit receives a route request frame including overall quality information on routes through which the route request frame has passed. The selecting unit selects a route request frame to be transferred to another communication device based on the quality information, from the route request frames received by the receiving unit through a plurality of routes. The transfer control unit transfers the route request frame selected by the selecting unit to the another communication device, and discards the route request frame when a quality value indicated by the quality information of the route request frame is smaller than a predetermined reference value.
