Abstract: A child safety seat includes an inner member, an outer member, and a support frame. The inner member has a seat part and a backrest part that extends upwardly from a rear end and lateral ends of the seat part. The outer member has a rear portion that is disposed behind the backrest part of the inner member, and a front portion that extends from a periphery of the rear portion and that is coupled to the inner member. The support frame includes a first subframe unit that is disposed behind and adjacent to the inner member and that is connected to the outer member, and a second subframe unit that extends between the inner and outer members from the first subframe unit.

Abstract: A caster includes a housing, a rotating member, and a caster. The housing defines an accommodation space having an open bottom end. The rotating member is disposed within the housing, and is rotatable between first and second angular positions. The caster is co-rotatable with the rotating member. One of the housing and the rotating member has first and second engaging portions. The other one of the housing and the rotating member has a third engaging portion, which engages the first engaging portion so that the caster is unfolded and disposed outwardly of the housing when the rotating member is at the first angular position and which engages the second engaging portion so that the caster is folded and disposed at a folded position and within the accommodation space when the rotating member is at the second angular position.

Abstract: An electronic device comprises a printed circuit board, a heat sink and a plurality of locking devices securing the heat sink to the printed circuit board. Each locking device comprises a shaft, a knob and an elastic member. The shaft has a plurality of outer teeth protruding outwardly from an outer surface of a top end thereof. The outer teeth are arranged along an axial direction of the shaft. The knob has an inner tooth meshing with the outer teeth of the shaft. The elastic member is compressed between a bottom of the knob and the heat sink. A length of the elastic changes when the inner tooth of the knob meshes with different outer teeth along the axial direction of the shaft to adjust a pressure of the locking device on the heat sink.

Abstract: When a safety belt storage assembly's storage is mounted to a main body of a child seat, the storage of the safety belt storage assembly may be selectively configured between an opened state and a closed state. When the storage of the safety belt storage assembly is configured at the opened state, a safety belt set stored within the housing can be taken out and further used to fasten the child seat to an adult chair. The opened state storage further prevents the child seat from mounting on a frame body. When the safety belt set is stored in the housing, the storage of the safety belt storage assembly can be configured to the closed state and the child seat is allowed to be mounted to the frame body.

Abstract: A child chair includes a seat and a frame. The seat is detachably mounted on the frame by using an engaging assembly. The engaging assembly includes an engaging device and a coupling device. The engaging device is movably mounted on the seat. The coupling device is mounted on the frame and coupled with the engaging device on the seat. The engaging device is cooperated with the coupling device between a locking position and a release position relative to the seat.

Abstract: A top frame unit of a baby crib includes a plurality of three-way couplers and a plurality of top frame rods. Each coupler includes a root part and first, second and third tube parts that extend in different directions from the root part. The root part is formed with a cap-receiving recess that is in spatial communication with the first tube part. Each top frame rod includes a rod body that has opposite first and second rod ends, and an anchor cap that is mounted on the first rod end of the rod body. Each top frame rod is extended removably through the first tube part of one of the couplers such that the anchor cap thereof is disposed removably in the cap-receiving recess, and such that the second rod end of the rod body is extendible removably into the second tube part of another one of the couplers.

Abstract: A bottom frame assembly for a baby crib includes pairs of first and second bottom frame rods, and a hub unit that includes stationary and rotary seats. The stationary seat is connected to the first bottom frame rods at diametrically opposite positions of the stationary seat. The rotary seat is mounted rotatably on the stationary seat, and is connected to the second bottom frame rods at diametrically opposite positions of the rotary seat. By adjusting the angular orientation of the rotary seat relative to the stationary seat, the angles formed between adjacent ones of the first and second bottom frame rods can be varied so that the bottom frame assembly can suit the specified length-to-width ratio of the baby crib.

Abstract: A fastener system is implemented to assemble a fabric element with a frame structure of a nursery device for supporting a baby occupant. The fastener system includes a first connecting structure joined with the fabric element and configured to complementarily mate with a second connecting structure having a protrusion extending along a support beam of the frame structure. The first connecting structure includes a flat affixing portion joined with an edge of the fabric element, and an engaging catch linked with the affixing portion through a joint portion. The second connecting structure complementarily mates within the engaging catch of the first connecting structure to fasten the fabric element with the support beam.

Abstract: Provided is a method and system for supporting IMS VCC based on an MIH. In a method of supporting a multimedia service for an MIH-based VCC, neighbor network information is obtained from an MIH server periodically or according to an event trigger and scanning the neighbor network. The capacity of at least one more candidate networks is detected from the scanning results to prepare a handover. A target network is determined among the candidate networks to reserve resources and a handover command event is generated to perform a domain transfer. The handover is completed after the performing of the domain transfer.

Abstract: A mini-size universal hydraulic excavator capable of performing independently many operating processes, such as digging, pushing, grabbing, drilling and chipping, having essentially three main sections, namely, a chassis carrying traveling device pivotally connected with an earth-moving means, a complete swivel upper carriage provided with a power generator and a driver's seat, and an excavating arm having a boom, a bucket arm, and a bucket. A hydraulic chipper can be connected to the main machine without the necessity of removal of the bucket and the earth-moving means, so that chipping and site clearing can be carried on simultaneously solely by one single machine. A backhoe bucket carrying a scraper employs a multi-bar linkage mechanism having a bucket body, a scraper, and a bucket arm so that the bucket can have sufficient bucket capacity in a relatively greater excavating revolving angle range.
