Publication number: 20160176676Abstract: A cable system A includes a cable 3 for connecting a base device 1 and a travelling body 2, a reel device 10 mounted on the travelling body 2, a motor controller 40 for controlling a motor 15 of the reel device 10, and a rotary encoder 16 (rotation sensor) for detecting rotation of a reel 12. The motor controller 40 basically makes the motor 15 free, when the reel 12 is rotating in an unreeling direction, and basically applies a rotational torque in a reeling direction to the reel 12, when the reel 12 is rotating in the reeling direction. Furthermore, even if the reel 12 is rotating in the unreeling direction, if an unreeling speed of the cable 3 exceeds a travelling speed of the travelling body 2, the rotational torque in the reeling direction is applied to the reel 12. Slackening of the cable 3 is thereby prevented.Type: ApplicationFiled: June 26, 2014Publication date: June 23, 2016Inventors: Shingo Tsukui, Seiji Oomura, Hidekazu Iwaki

Patent number: 9086499Abstract: A method and apparatus for tracking target objects includes a network of unidirectional sensors which correspond to nodes on the network. The sensors identify the presence of a target object, determine a first criteria for the relationship of the target object to the sensors and send a message to sensors neighboring the sensor. The message includes a unique identification of the target object and the first criteria. The sensors are ranked to determine which of the sensors should head a cluster of sensors for tracking the target object. Clusters are propagated and fragmented as the target object moves through a field of sensors.Type: GrantFiled: September 23, 2008Date of Patent: July 21, 2015Assignee: Purdue Research FoundationInventors: Henry Ponti Medeiros, Johnny Park, Avinash Kak, Hidekazu Iwaki
