Systems, devices, and techniques are provided for occupancy assessment of a vehicle. For one or more occupants of the vehicle, the occupancy assessment establishes position and/or identity for some or all of the occupant(s).

A biological sensor is provided with at least two sensors for detecting vibrations, and is configured so that the at least two sensors form layers. One of the at least two sensors is a first sensor used to acquire biological information, and one is a second sensor used to remove noise. A first cushion material for reducing vibrations is disposed between the first sensor and the second sensor. The first cushion material is integrally laminated with the first sensor and the second sensor. This facilitates accurate detection of biological information.

A vehicle seating system is described that can detect and optionally quantify a drowsiness state and/or and emotional state of a seat occupant in the vehicle. A seat is mounted in a vehicle and houses a wireless electromagnetic sensing system at least partially integrated into the seat. These sensed signals can be used to determine the occupant's state. When the state exceeds a threshold, then wireless stimulation emitters output a stimulation signal to the occupant to alter the emotion state or drowsiness state to move the occupant to below the threshold and to a calm state or an alert state. The system can also use additional physiological sensor to measure at least one of a heart rate, a respiration rate, or both of the occupant to be used with the electromagnetic sensing at the seat.

A method for monitoring a passenger compartment of a vehicle. The passenger compartment has at least one RFID transponder. A readout signal for reading out the RFID transponder is emitted in the method. In response to the emitting, a response signal of the RFID transponder is measured in order to obtain a measured value. Using the measured value, a degree of obscuration that represents an obscuration of the RFID transponder is ascertained in order to monitor the passenger compartment.

A passenger seat occupancy alert system for a vehicle is disclosed herein. The passenger seat occupancy alert system for a vehicle includes at least one sensor, a detection means, an in-vehicle display device, a speaker, and a controller. The passenger seat occupancy alert system is useful for sensing passenger occupancy of a vehicle and producing an alert.

A method of adjusting a vehicle seat includes detecting one of a current position of a vehicle occupant in a vehicle seat with one of a pressure sensitive fabric, a sound transmitter and transducer, and an electromagnetic field transmitter and transducer. A comfortable position is determined of the vehicle occupant. The vehicle seat is adjusted from the current position to the comfortable position. A vehicle seat assembly is also disclosed.

Systems, devices, and techniques are provided for occupancy assessment of a vehicle. For one or more occupants of the vehicle, the occupancy assessment establishes position and/or identity for some or all of the occupant(s).

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.

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.
