Abstract: A vehicle seat includes; a pair of frame members, the frame members forming a frame of at least one of a seat cushion and a seat back and being disposed at positions surrounding a seat region supporting an occupant with an interval therebetween; and a cloth spring member bridged between the frame members to cover the seat region. The cloth spring member has a shorter length in a bridging direction at least on one end side of the frame member in a longitudinal direction of the frame member than in a center portion of the frame member in the longitudinal direction; and the cloth spring member has elasticity.

Abstract: A control method for a vehicle includes: predicting a position of an eye point of an occupant after a state of a vehicle seat is changed based on amount of adjustment of an adjusting mechanism due to change in state of the vehicle seat; determining whether or not the predicted position of the eye point is located within a measurement range of a camera member installed to a steering member; and if it is determined that the predicted position of the eye point is not located within the measurement range of the camera member, moving the measurement range of the camera member toward the predicted position of the eye point synchronously with the steering member.

Abstract: Provided is a display unit that includes a first display section and a second display section. The first display section is configured to perform picture display and transmissive display. The picture display is based on a picture signal and performed on pixels in a partial region corresponding to a partial image part in a frame image represented by the picture signal, and the transmissive display is performed on pixels in a region other than the partial region. The second display section is provided behind the first display section, and configured to perform dummy display and transmissive display. The dummy display is performed on pixels in the partial region to display a dummy image that is one of a uniform image and a non-uniform image, and the transmissive display is performed on pixels in the region other than the partial region.

Abstract: A control method for a vehicle includes: predicting a position of an eye point of an occupant after a state of a vehicle seat is changed, based on amount of adjustment of an adjusting mechanism due to change in state of the vehicle seat; determining whether or not a display light reflected on a wind shield is passing through a predicted position of the eye point; and if it is determined that the display light reflected on the wind shield is not passing through the predicted position of the eye point, automatically operating a head-up display system or the adjusting mechanism so as to move one of a traveling path of the display light reflected on the wind shield and the eye point of the occupant toward the other.

Abstract: If relocation of a table with a high reference frequency is made possible, the database management method and system are arranged to improve performance according to the number of increased nodes and accumulate a reference frequency of each external storage unit allocated to each database management node. A data storage area for storing the table with a high reference frequency, located in the external storage unit, is specified as a shared data area to be referenced by plural nodes. The system is controlled to cause the nodes to refer to the shared table stored in the shared data area on any timing in parallel. This prevents load from being concentrated onto the node allocated to the data area.

Abstract: A parallel database management system with a database divided into a plurality of external memory units is disclosed. A control CPU, upon receipt of a request for access to the database, decides whether the access request is for storing or searching a record. For a record storage request, the control CPU determines an external memory unit to store the record using a hash function. In the case of a record search request, on the other hand, all the external memory units are searched in parallel without using the hash function thereby to obtain the desired record. The hash function is altered upon addition of an external memory unit.
