Abstract: In a case where an actual parking technique of a driver in a parking condition is different from a parking technique shown by a parking technique model generated in a same parking condition, a parking assist apparatus outputs a question to the user about whether or not assistance for the parking operation is desired to park the vehicle. In a case where the driver accepts the assistance for the parking operation, the parking assist apparatus provide the assistance for the parking operation to park the vehicle. Thus, useless parking assistance that the driver does not desire can be prevented, and parking assistance that is truly desired by the driver can be executed.

Abstract: Some structures and methods to reduce power consumption in devices can be implemented largely by reusing existing bulk CMOS process flows and manufacturing technology, allowing the semiconductor industry as well as the broader electronics industry to avoid a costly and risky switch to alternative technologies. Some of the structures and methods relate to a Deeply Depleted Channel (DDC) design, allowing CMOS based devices to have a reduced sigma VT compared to conventional bulk CMOS and can allow the threshold voltage VT of FETs having dopants in the channel region to be set much more precisely. The DDC design also can have a strong body effect compared to conventional bulk CMOS transistors, which can allow for significant dynamic control of power consumption in DDC transistors. Additional structures, configurations, and methods presented herein can be used alone or in conjunction with the DDC to yield additional and different benefits.
