An information processing device includes a location information obtaining unit that, from each of a plurality of imaging devices which is used in a mobile object and which searches for an object, obtains location information indicating the current location of the imaging device; and a deciding unit that, based on the location information of each of the plurality of imaging devices, decides on the imaging device to be used in searching for the object.

Provided are a digital find security system, method, and program which can reliably make a report to an employee closest to an event point and allow the employee to more promptly rush to the scene. In a digital find security system (100), a control unit (110) refers to facility layout information stored in a layout information storage unit (114A), and calculates moving distances between a suspicious person and respective mobile terminal devices close to a position of the suspicious person on the facility layout. Then, the control unit (110) corrects moving distances extracted for the respective employees by adding correction coefficients and converts these into moving time distances, and transmits information regarding the suspicious person to a mobile terminal device (30) at the shortest moving time distance to the position of the suspicious person.

A physical condition change detection device for detecting a change in physical condition of a subject includes a body-surface-side biological information detection unit that is configured to detect a variation in biological information obtained from a body surface of the subject and that is to face the body surface of the subject and an outside thermal variation detection unit that faces away from the body-surface-side biological information detection unit and that is configured to detect a thermal variation in an outside area separated from the body surface of the subject. The physical condition change detection device further includes a transmit unit configured to provide control to transmit detection data of the body-surface-side biological information detection unit and the outside thermal variation detection unit to the outside at every given time.

A face authentication system including a storage to store a face image of each of a plurality of persons who are permitted to enter in advance and information on a zone; an image processing unit to detect a face of at least one person in an image captured by at least one camera having identification information, and generate a face cut-out image of the at least one person; a zone determination unit to determine a zone where a person in the face cut-out image is captured; a collation unit to collate the face cut-out image with the face image of each of the plurality of persons; and an output control unit to, when it is determined that there is not a face of a person appearing in the face cut-out image, superimpose a detection frame indicating a face of a person who is not permitted to enter the zone.

A robot detects, through a sensor, the location and movement direction of a user and an object near the user, sets a nearby ground area in front at the feet of the user according to the detected location and movement direction of the user, controls an illumination device in the robot to irradiate the nearby ground area with light while driving at least one pair of legs or wheels of the robot to cause the robot to accompany the user, specifies the type and the location of the detected object, and if the object is a dangerous object and is located ahead of the user, controls the illumination device to irradiate a danger area including at least a portion of the dangerous object with light in addition to irradiating the nearby ground area with light.

Disclosed are a monitor subject monitoring apparatus, a monitor subject monitoring method, and a monitor subject monitoring system configured to determine a first body state of a subject, based on an image data of the subject, and to determine a second body state of the subject, based on physiological data of the subject, wherein the subject monitoring apparatus, the subject monitoring method and the subject monitoring system are operable, when it is determined that one of the first and second body states of the subject is not abnormal, to re-perform a corresponding one of the determinations, and then determine whether or not a notification indicating that the subject is in an abnormal state should be issued, based on a result of the re-performed determination about the one of the first and second body states.

A method of locating a short circuit in a system including a set of components electrically connected in a loop, such as a fire protection system. It is iteratively determined in which location of a set of possible locations a short circuit is located. Each iteration involves determining in which of two subsets of a set of remaining locations the short circuit is located, and eliminating from the set of remaining locations the subset in which the short circuit is determined not to be located.

The invention relates to a bus system (1) comprising a control unit (2) and at least one bus node (3.1, 3.2, 3.3). The control unit (2) is allocated at least two data communication interfaces (2.1, 2.2) which are respectively designed to transmit and receive data. The at least one bus node (3.1, 3.2, 3.3) comprises a bus coupler having at least two data communication interfaces (3.11, 3.12; 3.21, 3.22; 3.31, 3.32) respectively designed to transmit and receive data. The control unit (2) and the at least one bus node (3.1, 3.2, 3.3) are respectively connected together via their data communication interfaces and corresponding two-point connections (8) to form a ring topology. The bus coupler of the at least one bus node is designed to directly and without delay transmit, and thus forward, data received at one of its at least two communication interfaces via its other data communication interface.
