Abstract: Methods and apparatuses involving biocompatible structures for tissue engineering and organ replacement and, more specifically, biocompatible structures formed by three-dimensional fabrication, are described. In some embodiments, the biocompatible structures are scaffolds for cells that can be used as tissue engineering templates and/or as artificial organs. The structures may be three-dimensional and can mimic the shapes and dimensions of tissues and/or organs, including the microarchitecture and porosities of the tissues and organs. Pores in the structure may allow delivery of molecules across the structure, and may facilitate cell migration and/or generation of connective tissue between the structure and its host environment. Structures of the invention can be implanted into a mammal and/or may be used ex vivo as bioartificial assist devices.

Abstract: A power switch apparatus is disclosed wherein the switch apparatus is applicable in an electronic product comprising a switch device capable of being switched between ON and OFF conditions. The power switch apparatus comprises an active element and a flexible arm. The active element installed inside the electronic product comprises a first connector and is coupled to the switch device. The ON and OFF conditions of the switch device correspond to the different positions of the active element. The flexible arm comprises a second connector and a contactor. The second connector is used to clip with the first connector at the ON condition. The electronic product is configured such that the contactor is not covered and remains accessible. The movement of the contactor is able to transform the shape of the flexible arm and to release the clipping relation between the first connector and the second connector.

Abstract: A wireless communication apparatus integrates a flat speaker (33) onto a liquid crystal display (12) or a rotational shield (3) of the apparatus.
