A seat air-conditioning device includes: a blower; a first ventilation path through which air is drawn in by the blower from a first inlet in a seat base of a seat on which a person sits; a second ventilation path through which the drawn air is discharged from a first outlet in the seat; a third ventilation path that is different from the second ventilation path and through which the drawn air is discharged from a second outlet in the seat; and an outlet ventilation path selection switch that is between the blower and the first and second outlets and selects at least one of the second and third ventilation path to which the drawn air is to be led. The first inlet is vertically below the first outlet and the second outlet.

An on-vehicle device that is to be mounted in a vehicle includes: an electrical component including a sensor; a power supply module including a power receiving antenna and a power supply circuit configured to convert radio waves for power feeding received by the power receiving antenna into electric power and supply the electric power to the electrical component; and a line member having flexibility and electrically connecting the electrical component to the power supply module.

A vehicle seat includes a seat cushion and a seatback. The vehicle seat has a plate-shaped pressure-receiving member configured to receive a load from an occupant seated on the vehicle seat and a radio wave sensor fixed to the pressure-receiving member. The radio wave sensor is configured to acquire information about the occupant by emitting radio waves toward the occupant and detecting the radio waves reflected off the occupant. The pressure-receiving member includes a plurality of first ribs that protrudes from a backside of the pressure-receiving member, which is a side facing away from the occupant, in a direction away from the occupant, and a plurality of second ribs that protrudes from the backside in a direction away from the occupant, the plurality of second ribs crossing the plurality of first ribs. The radio wave sensor includes at least one fixing part that is fixed to the pressure-receiving member. The at least one fixing part includes a first fixing part that is fixed to a surrounded area that is surrounded by the plurality of first ribs and the plurality of second ribs on the backside.

The invention relates to an apparatus for measuring pressure and/or humidity, and to a method for measuring pressure and/or humidity. The apparatus comprises at least one sensor for measuring pressure and/or humidity, wherein the sensor comprises at least one capacitor comprising at least two electrodes that are arranged, in particular, in a horizontal direction along and on an, in particular, flexible support material relative to one another. At least one dielectric layer is arranged between the electrodes. The invention is characterised in that at least one at least partially liquid-permeable and/or liquid-absorbing moisture layer is arranged at least in some places on a side, facing away from a support material, of at least one electrode and/or the dielectric layer. The at least one electrode and/or the dielectric layer are thus then arranged between the support material and the moisture layer in a transverse direction. In this way, a capacitance is at least partially changed by the liquid at least partially hitting the dielectric layer, wherein a processing unit is designed and provided to measure and/or store this change, so as to create a capacitive moisture sensor.

An airflow sensing seat comprises a seat body (1), an airbag (2), a sensing assembly (3), and a micro control unit (4). The airbag (2) is provided in the seat body (1). A deformable support structure (21) is provided in the airbag (2). The support structure (21) is used to maintain an appropriate amount of gas in the airbag (2). A transmission mechanism (5) is provided between the airbag (2) and the sensing assembly (3). The transmission mechanism (5) is used to transmit gas disturbance in the airbag (2) to the sensing assembly (3). The sensing assembly (3) is used to generate a corresponding analog electrical signal according to the gas disturbance. The sensing assembly (3) is electrically connected to the micro control unit (4). The sensing assembly (3) transmits the analog electrical signal to the micro control unit (4). The micro control unit (4) is used to perform analysis and computation on the analog electrical signal so as to acquire a biological signal of a user. The invention also relates to a method for adjusting a smart seat. The airflow sensing seat and an adjustment method therefor obviate the need to embed other electronic pressure sensing assemblies in the seat body, thereby avoiding damage to an electronic pressure sensing assembly due to frequent pressing thereon. In addition, the airbag does not need to be inflated during testing, thereby reducing costs.

A child transportation system is disclosed. The system includes a seating component and various other modules. The system can check whether a seating component is located in a vehicle, whether the seating component is a proper component given the weight and height of the child in the seat, that the seating component is properly secured in the vehicle, and that the system is operating correctly. The system can monitor various conditions of the seat and the environment, and can provide alarms to users when cheks are not completed or dangerous environmental conditions are present, or when a child is left behind in a vehicle.

A detection device includes a first sensor configured to transmit a first electromagnetic wave to a first range and receive the first electromagnetic wave reflected in the first range, a second sensor configured to transmit a second electromagnetic wave to a second range different from the first range and receive the second electromagnetic wave reflected in the second range, and a processor configured to calculate information on an object reflecting the first electromagnetic wave and the second electromagnetic wave based on a first signal output from the first sensor and a second signal output from the second sensor.

A blood alcohol level sensing system for a vehicle is steering wheel with infrared sensors that are able to detect variations in body chemistry from contact with the palms of the hands to determine if a driver is either alcohol impaired or impaired from certain medical conditions that might affect driving. The system has a digital readout that may be located on the dashboard of the vehicle, and the readout may also be transmitted to a cell phone. In the event of an exceedance of a predetermined set point, an interlock will interrupt the start circuit of the vehicle to prevent it from starting.

A seating system for a vehicle includes a vehicle seat, a first Doppler radar sensor positioned within the seatback and aligned with the heart of a person sitting in the seat, a second Doppler radar sensor positioned within the seatback and offset from alignment with the heart, and a controller. The first sensor transmits a signal toward the heart and receives a first reflected signal as modulated by heart movement and by a random motion of the person. The second sensor transmits a signal toward an anatomical location of the person offset from the heart and receives a second reflected signal as modulated by the random motion of the person. The controller generates a biometric signal corresponding to the heart movement, without random motion artifacts, based on a difference between the reflected signals whereby the biometric signal is indicative of cardiac information of the person.

A seating system for a vehicle includes a vehicle seat, individually selectable and controllable electromagnetic coils individually positioned at respective locations within the seat corresponding to anatomical locations of a person sitting in the vehicle seat, and a controller. The electromagnetic coils to generate electromagnetic fields when activated. The controller to individually activate a subset of the electromagnetic coils to deliver electromagnetic energy to the anatomical locations of the person corresponding to the respective locations within the vehicle seat of the activated electromagnetic coils.
