Vessel azimuth control apparatus and azimuth control method

The objective is to obtain an azimuth control apparatus and an azimuth control method that require no excessive memory capacity and calculation time for information processing and can cope with a disturbance by adaptively adjusting a control gain while calculating changing vessel parameters online. The vessel azimuth control apparatus has an azimuth control unit that outputs a steering-angle command signal for making a vessel turn to an azimuth to which the vessel should travel, based on an azimuth command signal generated by an azimuth command generation unit, a yaw-angle signal, and a yaw-angular-velocity signal, a steering-angle control unit that controls a rudder based on the steering-angle command signal, and a control gain adjustment unit that calculates respective frequency responses of the yaw-angle signal and the yaw-angular-velocity signal to a steering-angle signal outputted by a steering-angle detection unit and then adjusts a control gain of the azimuth control unit.

An elevator safety control device realizing suppression in increase in cost and labor hour of installation and maintenance without deteriorating safety of normal safety control functions even when a plurality of safety control functions are provided. The elevator safety control device includes an independence assurance unit assuring independence of a safety control function. The independence assurance unit assures independence of each of the safety control functions by monitoring whether or not the safety control function accesses a memory other than a permitted region. When the independence assurance unit detects an access to the memory other than the permitted region by a predetermined safety control function, the elevator safety control device stops a car.

Elevator safety control device

There is provided a contents' relationship visualizing apparatus including a usage history acquiring unit for acquiring usage histories of multiple contents, a users' set specifying unit for specifying a content's users' set indicating users utilizing each content by use of the contents' usage histories, a similarity calculating unit for calculating a similarity between the specified users' sets by use of a similarity index, and a network creating unit for creating a network indicating a relationship between the contents by use of the calculated similarity between the users' sets.

Contents' relationship visualizing apparatus, contents' relationship visualizing method and its program

Each of a master node and a slave node has a safety data processing unit and a high reliability communication unit. At the time of transmission, the safety data processing unit creates a safety data packet including data about safety and the high reliability communication unit creates a communication data packet including the safety data packet and transmits the communication data packet a predetermined number of times. At the time of reception, the high reliability communication unit acquires and outputs a safety data packet by determining one of one or more communication data packets having the same contents which it has received properly as an effective packet, and the safety data processing unit analyzes a state concerning the safety of a system on the basis of the data about safety acquired from the safety data packet.

An information processing apparatus includes a network structure generation unit that generates a network structure showing relations formed between registered users at a predetermined time based on user information containing attribute information showing attributes of the registered user registered with a social networking service (SNS) and registration time information showing a registration time of the registered user, and relation information containing relation formation information showing a relation formed between the registered users on the SNS, and relation formation time information showing a relation formation time, a network image generation unit that generates a network image representing the generated network structure with the registered user as a node and a relation formed between the registered users as an edge, and a network image display unit that chronologically displays the generated network images at a plurality of the predetermined times. Accordingly, a change of SNS operation conditions can efficiently be grasped.

Information processing apparatus, information processing method and program for generating and displaying network structures

A memory diagnosis apparatus include an intra-word testing unit that tests for a coupling fault in each bit in each word in a memory, an inter-word testing unit that tests for a coupling fault between words in each sub-array each being plural words in the memory, and an inter-block testing unit that tests for a coupling fault between sub-arrays in the memory.

Memory diagnosis apparatus

In an elevator control apparatus, the presence/absence of an abnormality in an elevator is monitored by an abnormality monitoring portion. The abnormality monitoring portion makes a determination on the presence/absence of an abnormality in the elevator based on information from a sensor, and outputs a signal for stopping a car upon detecting an abnormality. The history of information on the result of determination by the abnormality monitoring portion is recorded in a history information recording portion.
