3results about How to "Simple and intuitive operation" patented technology

This invention discloses a weak force sensor based on a teardrop-shaped micro / nano optical fiber and its fabrication method. The sensor comprises a biconical micro / nano optical fiber, a single-conical optical fiber, a quartz capillary tube, and a PDMS microsphere. The biconical micro / nano optical fiber is symmetrically bent, with the central waist region fiber forming a teardrop-shaped ring. The two ends of the teardrop-shaped micro / nano optical fiber ring are sequentially connected to portions of the waist region fiber, a transition region fiber, and a standard fiber. This invention utilizes the sensitive self-sensing capability of micro / nano optical fibers to achieve integrated signal input and output, greatly simplifying the measurement feedback mechanism of the sensing system and reducing overall cost. Furthermore, it is simple and intuitive to operate, reducing the technical requirements for operators. In terms of sensor fabrication, the main raw materials are standard optical fiber and quartz capillary tube, both of which are extremely low-cost. Therefore, this micro / nano optical fiber sensor exhibits significant cost-effectiveness.

The utility model relates to a one-button type getting-up and lying system of an electric bed, which is convenient to operate and suitable for weak or elderly people to use. The bed body is composed of three sets of bed plates, namely an upper body bed plate, a fixed bed plate and a leg bed plate, and the three sets of bed plates can move independently and are fixed to a base. The two groups of lifting devices respectively control the lifting of the upper body bed board and the leg bed board, and the actions are managed by the control system. A memory is built in the control system, a getting-up process is recorded and matched with a handheld remote control device, and the process can be started by pressing down a getting-up key. The process comprises the following steps: firstly, raising the leg bed board to 20-35 centimeters; then, the upper body bed plate is started, and the back is lifted to the highest position; and finally, the leg bed plate descends to be flush with the bed surface. The whole process can be automatically completed through one key, and convenience, rapidness and safety are achieved.
