Abstract: According to one embodiment, an elevator system includes a camera, a passenger detection module and a controller. The camera is capable of imaging a particular range in a direction from a vicinity of a door of a car to a hall when the car arrives at the hall. The passenger detection module detects presence or absence of a passenger who intends to get into the car by focusing on movement of a movable body within a specific area by using a plurality of time-series continuous images which are captured by the camera. The controller controls an opening/closing operation of the door based on a detection result of the passenger detection module. A width of the area is being set greater than at least a width of the door.

Abstract: It is possible to leave records with which analysis of a cause can be efficiently performed when a trouble occurs in an observation target system and realize reduction in the size of the records at the time of recording. The present invention is proposed as a log recording apparatus. This log recording apparatus is provided with: a cell number storage unit to store a cell number table with cell numbers, each being data for identifying a cell number from a state/event combination; a cell number generation unit acquiring data indicating an event and a state from an observation target system, to determine a cell number corresponding to the event and the state with the use of the cell number table stored in the cell number table storage unit and the data indicating the event and the state; a log data generation unit to generate log data which includes the cell number determined by the cell number generation unit; and a log data recording unit to record the log data generated by the log data generation unit.

Abstract: A counter example analysis support apparatus includes a counter example storage storing the counter example being a transition sequence of state and event that has not satisfied a verification condition as a result of the model checking; comprising: a related item list storage storing a related item list being a list associating a detection event, which is an event for detecting and generating the other-state, and a detected state, which is a state for determining the existence of the generation of the detection event; and a searching unit outputting a possible problem part from the counter example, wherein the searching unit determines whether a state included in the counter example is the detected state, and if the state included in the counter example is the detected state, determines whether a detection event corresponding to the related item list is generated before the detected state transits to a next state.
