Service components are published externally as normal web services and can thus be employed by webbased applications. In order to improve reusability and testability of service components, the concept of composition pattern is also proposed, which presents the relationships among service components. The relationships and relationship compositions have a rigorous semantic, so that composite components can be validated at the configuration stage. The composition patterns support to integrate service components of various levels of granularity. Experience indicates that the application assembly can effectively be conducted by understanding, selecting, and reusing components easily.展开更多

This web-based boot includes boot body, lifting device and support to support the feet and the lifting device to fix on the boot body. The support uses the lifting device to connect to the bottom of the boot body, and through the lifting device function, it can have lifting displacement to the boot bottom. The workers put foot fixed on the support, so as to make the inflating lifting boots walk along with the workers. The adjusting lifting device can make support member move far or near the bottom direction of boot body. The workers can lift higher or lower along with the support. The workers can adjust the lifting device according to specific work height, without using or moving ladder or stool, to save time and improve the work efficiency.展开更多
