  • Patent number: 11642959
    Abstract: A transfer for a four wheel drive vehicle includes first and second distribution mechanisms that respectively include first and second clutches configured to be controlled to a half-engaged state. The first and second distribution mechanisms distribute a portion of power outputted from a power source to a second transmission mechanism respectively through the first and second clutches. A first difference is different from a second difference. The first difference is a difference between a gear ratio from an input shaft of the first clutch to a first driving wheel and a gear ratio from an output shaft of the first clutch to a second driving wheel. The second difference is a difference between a gear ratio from an input shaft of the second clutch to the first driving wheel and a gear ratio from an output shaft of the second clutch to the second driving wheel.

  • Patent number: 10785071
    Abstract: A wireless communication apparatus includes components below. An equalization unit performs equalization processing on a part of a received signal corresponding to a first range and a part of the received signal corresponding to a second range. The first range includes detection target data. The second range is outside the first range. A replica generation unit decomposes the second range, on which equalization processing has been performed, into a plurality of signal components, and reproduces the part of the received signal corresponding to the second range for each of the signal components to generate a replica of an interference component. An interference cancellation unit cancels the interference component from the part of the received signal corresponding to the first range by using the replica. A data extraction unit extracts the detection target data from the received signal.

  • Publication number: 20080300101
    Abstract: The present invention provides a system for providing an improved compact power transfer unit for use in motor vehicles having a front wheel drive transverse based engine and transaxle, and, more particularly, to a power transfer unit for use with a transaxle arrangement capable of providing all-wheel drive or four-wheel drive. The present invention discloses a planetary gear utilizing a fixed ring gear, the planetary gear capable of selectively engaging a low range output from the power transfer unit for propelling the vehicle when driven in off-road conditions requiring higher torque and slower speeds. The vehicle driver can selectively engage a normal, high range where torque flows through the planetary gear directly to the drive shaft with no gear reductions, or the driver may selectively engage the low range where the torque flowing into the planetary gear is redirected and reduced thereby providing higher torque with reduced speed.

The fast cell search method disclosed detects the “class indices” with simple processing. In a system deployment that uniquely maps sequences of certain class indices along with a circular shift amount in time domain to certain cells/cell IDs, the identification of a sequence index, and its circular shift will therefore provide an identification of the cell ID.
