Electronic devices and methods are provided in which a pressure applied, by a driver, to a seat of a moving object driven by the driver is sensed. A state of the driver is determined based on frequency characteristics with respect to a change in the pressure sensed by the sensor.

A seatback includes a lower frame, an upper frame, and a hinge coupling the lower and upper frames. An actuator is fixed relative to the lower frame, and a cable extends from the actuator to the upper frame. In the event of a collision, the actuator pulls the cable, and the upper frame moves from an upright position to a bent position relative to the lower frame.

A heat flux sensor is installed in such a way that heat flux emanating from a biological object present at a predetermined position is detectable. It is determined whether or not a biological object is present at the predetermined position by comparing sensing results of the heat flux sensor with determination criteria. The determination criteria is preset according to heat flux that can be sensed when a biological object is present at the predetermined position. When the sensing results of the heat flux sensor satisfy the determination criteria, in other words, when the heat flux sensed by the heat flux sensor is the heat flux emanating from a biological object, it is determined that a biological object is present at the predetermined position. Consequently, it is possible to realize accurate detection of a biological object.

Load sensors are disposed on four corners of a seat cushion. An occupant decision section of an occupant detection ECU decides a type of an occupant on a vehicle seat based on loads detected by the load sensors. A CRS changing section that prohibits the occupant decision section from changing a decision to a decision result that an adult is seated in the vehicle seat and changes the decision to a decision result that a child seat is attached on the vehicle seat when an engagement of a tongue plate with a buckle of a seat belt device is detected by a buckle switch and a buckle load calculated by buckle load calculation section is less than a predetermined buckling load threshold in a case where the occupant decision section decides that an adult is seated in the vehicle seat.

A vehicle seat is adapted to be moved relative to a floor of a vehicle. The seat includes a seat bottom that can be moved relative to the floor and a seat back that can be moved relative to the seat bottom.

A vehicle seat includes a seat bottom and a seat back. The seat back is coupled to the seat bottom and arranged to extend in an upward direction away from the seat bottom. The vehicle seat further includes an electronics system.

Provided is a security device, comprising: a sensor that senses a presence in a vehicle and generates a presence signal; an ignition state detection device that detects a state of the vehicle, and generates a status signal; and a rules processor that determines from the presence signal and the status signal whether an alarm or message is to be generated.

A vehicle seat includes a seat bottom adapted to slide along a floor, a seat back coupled to the seat bottom, and powered means for rearranging the vehicle seat by sliding the seat bottom along the floor and/or pivoting the seat back relative to the seat bottom.

Arrangement for controlling a component having multiple states includes a device that generates a signal at a frequency that enables it to be conducted through a human body, and a conductive surface coupled to the device, situated in a position accessible by a part of the human, and which enables proximity or contact of the part of the human to the conductive surface to develop a reactive coupling between the human and the conductive surface. The component has multiple, different states and is controlled by the human to change from a first state to a second state upon completion of an electrical circuit including the component, the conductive surface and the device upon developing reactive coupling between the human and the conductive surface when the device is generating the signal conducted through the human. The component may be a vehicular component such as a door or window.

A passenger restraint device for amusement rides and a method for retaining at least one passenger by means of the restraint device. The device comprises at least one restraint element provided with at least one contact surface intended to be placed in contact with at least one part of the body of a passenger. The restraint element is movable between at least one open position, in which the restraint element is not in contact with the passenger and at least one closed position in which the restraint element is in contact with at least one part of the passenger's body.

The restraint element comprises at least one sensor to detect a contact between the restraint element and at least one part of the body of the passenger, preferably a contact with a passenger's thighs.
