Abstract: A retractable neck pillow has multiple retractable elements sequentially connected along a retracting direction. Each retractable element is made of a flexible material, is tubular, and is capable of retracting along the retracting direction. Two ends of the retractable neck pillow can be pushed by a user to shorten for storage. The retractable neck pillow is convenient in usage and is easy to be stored.

Abstract: A pillow has a supporting structure, a cushion, multiple flexible sensors, and a controlling unit. The supporting structure has a supporting plate. The supporting plate has multiple supporting elements disposed at intervals. Each of the supporting elements is sheet-like. Each of the supporting elements is independently deformable by being independently pressed and independently restoring. The cushion is elastic and is supported by the supporting structure. Each of the flexible sensors is mounted to a corresponding one of the multiple supporting elements. The controlling unit is electrically connected to the multiple flexible sensors. When a user rests his head on the pillow, the user may press the flexible sensors to control a controlled device such as a speaker or a projector.

Abstract: A pillow has an independent-supporting structure, a headrest cushion, and a supporting cushion. The independent-supporting structure has a supporting plate. The supporting plate has multiple supporting elements disposed at intervals. Each one of the multiple supporting elements is elongated and is able to be independently pressed, to independently restore, and to be independently deformed. The multiple supporting elements are parallelly disposed and apart from one another. The headrest cushion is resilient and is supported by the supporting plate for supporting a head of a human. The supporting cushion is resilient and is disposed below the multiple supporting elements for supporting. When a user rests his head on the pillow, each supporting element is deformed independently to provide independent support to the cervical spine of the user.

Abstract: A stress analysis system for performing analysis of a force exerted on a test object is provided, wherein the test object is defined to have a plurality of predetermined areas at different positions thereof. The stress analysis system includes: an analysis module, and at least two stress bearing modules separate from each other, each of which is located at one of the predetermined areas. Each of the stress bearing modules includes a supporting strip component and a feature sensor, wherein the supporting strip component is able to produce a stressed feature in at least one spatial dimension when being subjected to the force, and the feature sensor is able to sense a stress state of the corresponding predetermined area of the test object in at least one spatial dimension, such that the stress analysis system can accurately analyze the stress state of the test object.

Abstract: A pillow has a supporting structure and a cushion. The supporting structure is made of composite materials and is pre-stressed and resiliently bended. The cushion is resilient and covers the supporting structure. With the supporting structure and the cushion, the pillow provides two-stage resilient support. When a user rests his head on the pillow, the cushion is compressed easily at first, and then the supporting structure being resiliently bended provides sufficient support to the cervical spine of the user, making the cervical spine of the user rest in natural relaxation when the user rests on the pillow.

Abstract: A molding machine, which is operable to mold plastic granules into a plastic piece, includes a machine body, a platform, a heater, and a pressing unit. The platform is installed at the machine body and defines a molding cavity to receive the plastic granules. The heater is installed at the machine body adjacent to the platform. The pressing unit is installed at the machine body and disposed above the platform. The pressing unit includes a pressure cylinder, a telescopic rod driven by the pressure cylinder to extend downward and retract upward, and a pressing plate coupled to the telescopic rod and disposed to correspond in position with the molding cavity, and driven by the pressure cylinder to move relative to the platform.
