摘要： A collapsible infant bathtub in the present invention is made of a base, a headrest, a footrest and pressing devices. On each end of the headrest and footrest is respectively provided with a slider to receive each head end and foot end of the base. When being pulled outward along each skirt of the base, each slider will touch the slant surface of the button of each pressing device to force each button to shrink inside for each slider to pass on, and then each button will protrude outward the hole of each slider and stop each slider so as to prevent the headrest and footrest from being wholly pulled outward. On the bottom of each slider is provided with a catching member so as to stop against each stopping block of the base to firmly secure the headrest and footrest. After each button being pressed to shrink inward, each slider can be pushed inward along each skirt of the base to a secured position so as to collapse the infant bathtub for storage or carriage.

摘要： A reverse-prevent structure for a baby walker includes several slide-preventing strips, a moving wheel and a reverse-preventing wheel. The characteristic of the present invention lies in the reverse-preventing wheel, which is composed by an inner tray and an outer casing. The inner tray is fixed and has an inwardly protrudent annulus. The annulus is provided with a angle-shaped hollow for a movable catch block to be placed in. The movable catch block is provided to interact with the ratchets encircling the inner wall of the outer casing. When the outer casing is rolling forward, the ratchets successively slide over the movable catch block, and the outer casing can advance smoothly. If the outer casing rolls in the reverse direction, one of the ratchets will be stopped by the movable catch block immediately, and the catch portion of the movable catch block will be caught in the notch between two ratchets. Therefore, the outer casing as well as the reverse-preventing wheel will be prevented from rolling in the direction.

摘要： The present disclosure relates to a method and an apparatus for clock distribution in network. The method performed by a first clock distribution apparatus may comprise: determining (S101) whether the first clock distribution apparatus is in a first state; generating (S102) information indicating a remaining time duration for the first clock distribution apparatus keeping a preconfigured accuracy, when the first clock distribution apparatus is in the first state, and transmitting (S103) the information indicating the remaining time duration. According to embodiments of the present disclosure, the downstream apparatus may obtain more information for selecting an upstream clock source.

摘要： The present disclosure provides a method (200) for synchronization source selection. The method (200) includes: detecting (210) a transition of a Quality Level, QL, of a synchronization source candidate from a first level to a second level; starting (220) a timer in response to the transition; and refraining (230) from selecting the synchronization source candidate as a synchronization source before expiry of the timer.
