  • Publication number: 20240074549
    Abstract: A watchband can comfortably secure an electronic device to a wrist of a user. The watchband can include a base having a contact surface opposite an engagement surface, contact loops on the contact surface for contacting a user, and engagement loops on the engagement surface for engaging hooks. The hooks can be provided on the engagement surface, opposite some of the contact loops. Edge sections of the base can wrap around a central section to define an end of the base. A tab can extend from an end of the base to facilitate attachment, adjustment, and/or removal of the watch band. The tab can further help maintain the assembled parts in place to enhance durability of the watchband.

  • Patent number: 11644094
    Abstract: A power unit includes a prime mover and a belt continuously variable transmission. The belt continuously variable transmission includes a drive pulley, a driven pulley, a belt wound around the drive pulley and the driven pulley, and a housing forming an accommodation space in which the belt is disposed. The belt continuously variable transmission changes a speed of rotation produced by drive power output from the prime mover. The power unit further includes a temperature sensor configured to detect a temperature of the belt or a temperature corresponding to the temperature of the belt.

  • Patent number: 11535099
    Abstract: [Technical problem] To provide a power transmission mechanism for a four-wheel drive vehicle in which a prime mover is disposed at a low position to lower the center of gravity of the vehicle while a driving path from a transmission to a front wheel differential mechanism is also shortened. [Solutions] In a power transmission mechanism for a four-wheel drive vehicle, the power of a prime mover is transmitted to a front wheel differential mechanism which is disposed in front of the prime mover, and to a rear wheel differential mechanism which is disposed behind a transmission, through the transmission which is disposed behind the prime mover. The transmission comprises a front and rear wheel drive shaft that extends along the longitudinal direction of the vehicle body. The transmission is arranged separately from the prime mover and a rear axle drive device. The rear end portion of the front and rear wheel drive shaft is connected to an input shaft of the rear wheel differential mechanism.

  • Patent number: 11312235
    Abstract: A drive switching mechanism of a utility vehicle includes: a two-wheel drive and four-wheel drive switching device that switches between two-wheel drive and four-wheel drive of the utility vehicle; and a control unit that controls the drive switching mechanism. The two-wheel drive and four-wheel drive switching device switches between two-wheel drive and four-wheel drive by using a first clutch. The control unit permits the two-wheel drive and four-wheel drive switching device to switch from two-wheel drive to four-wheel drive when a rotation difference of the first clutch becomes equal to or smaller than a predetermined value.
