There is provided a notification system that, when a user misplaces luggage or a mobile terminal on a seat, promptly notifies the user of the misplaced luggage or the misplaced mobile terminal. A notification system 1 includes a seat S; a luggage detection unit 31 that detects a presence of luggage on the seat or in the vicinity of the seat, the luggage being held by a user; a seating detection unit 32 that detects whether or not the user is seated on the seat; a notification unit 33 that notifies the user of presence or absence information of the luggage; and a control unit 20 that is connected to and controls the luggage detection unit and the notification unit. When the luggage detection unit detects the luggage after an elapse of a predetermined time from when the seating detection unit has detected that the user has left the seat, the control unit causes the notification unit to notify the user that the luggage has been detected.

To provide a sensor unit that can be easily attached to and detached from a seat in which a seated occupant is seated, and a seat equipped with a sensor unit. A sensor unit includes a sensor module including a biological sensor that detects a biological signal of a seated occupant, and a wireless communication unit that is connected to the biological sensor to wirelessly transmit the detected biological signal to an outside; and a sensor holder that holds the sensor module. The sensor holder includes a seat attachment portion detachably attached to an attached portion that is provided in a front surface of a seat cushion at a position at which the seated occupant is abuttable against the attached portion.

The present invention provides a deformation detection sensor which combines a magnetic resin dispersing a magnetic filler in a resin with a magnetic sensor, of which stability of detection property is highly enhanced.

The present invention thus provides a deformation detection sensor which comprises: a cushion pad which comprises a magnetic resin, in which a magnetic filler is contained, and a polymer foam in which the magnetic resin is included, and a magnetic sensor that detects a magnetic change caused by a deformation of the cushion pad, wherein the magnetic resin has an elastic modulus of 0.1 to 10 MPa, and a production thereof.

A method of integrating a device in upholstery of a foam seat element, including the steps of: placing the device in a plastic bag or surrounding it with a plastic film; placing the assembly in an injection mold; and injecting foam to form the seat element in one piece.

A process is provided that uses a sensor system incorporated into the passenger cabin of a vehicle to detect children and/or pets left unattended and who are therefore at risk of serious injury or death due to heat stroke. If an unattended child or pet is detected, a variety of alerts are issued over time, the escalating nature of the alerts intended to insure a rapid response. After the system has operated long enough to insure that no child or pet has been left behind, the sensor system is automatically placed into a standby mode. In standby mode the sensor system may either be turned completely off in order to minimize off-line power consumption or it may be incorporated into an on-board security system.

A car seat pressure sensor device with wireless communication includes a wireless transmitter and a pressure sensor assembly. The wireless transmitter is configured for wirelessly communicating with a portable electronic device via a wireless signal. The pressure sensor assembly includes at least one pressure sensor and is interconnected with the wireless transmitter. The pressure sensor assembly is operable to turn on or off the wireless signal from the wireless transmitter. The pressure sensor device is configured to turn on the wireless signal from the wireless transmitter for communication with the portable electronic device when the pressure sensor assembly senses a certain weight, and turn off the wireless signal from the wireless transmitter for communication with the portable electronic device when the pressure sensor assembly does not sense the certain weight.

An infant anti-abandonment system and method includes an electrical communication network installed OEM into a vehicle, a transmitter coupled to the electrical communication network including, a plurality of weight detection sensors installed in the vehicle seats and at least one child car-seat, a wireless link between the electrical communication network and the plurality of weight detection sensors, a timer and an alarm. The infant anti-abandonment system and method is useful for alerting as to child-occupancy in an unattended vehicle.

A seating structure includes a base, a seat, a backrest connected to the seat, and an electronic circuit supported by the base. The seat or the backrest includes a carrier and a suspension material secured to the carrier and spanning across an opening formed by the carrier. The suspension material includes a plurality of electrostatic discharge fibers. The electronic circuit is coupled to the electrostatic discharge fibers. The electronic circuit includes an electronic processor and a sensor. The sensor is configured to generate an output signal indicative of an electrical parameter of one of the electrostatic discharge fibers. The electronic processor is configured to apply a drive signal to one of the plurality of electrostatic discharge fibers, receive the output signal from the sensor, and determine a state of the seating structure based on the output signal from the sensor.

The present invention provides a deformation detection sensor which combines a magnetic resin dispersing a magnetic filler in a resin with a magnetic sensor, of which stability of detection property is highly enhanced. The present invention thus provides a deformation detection sensor which comprises: a magnetic resin-containing polymer foam which comprises a magnetic resin, in which a magnetic filler is contained, and a polymer foam in which the magnetic resin is included, and a magnetic sensor that detects a magnetic change caused by a deformation of the magnetic resin-containing polymer foam, wherein the magnetic resin has a convex portion on either a surface facing the magnetic sensor or a surface facing opposite to the magnetic sensor, and its production method.

It is provided a massage device for a vehicle seat having at least one massage element, which moves a contact surface of the vehicle seat by means of an electromechanical actuator for the purpose of massaging a person in the vehicle seat. The massage element has a spring element, whereof the shape can be altered with respect to the contact surface of the vehicle seat by a restoring element containing the electromechanical actuator.
