Abstract: A multi-antenna system for harvesting energy and transmitting data includes an energy storing unit, antenna transmission units, and a load unit. Each antenna transmission unit includes an antenna module, a splitting module, an energy generation module, and a data processing module. The splitting module splits a wireless signal received by the antenna module into a first splitting signal and a second splitting signal and transmits the first splitting signal to an energy generation module to convert the first splitting signal into electrical energy stored in an energy storing unit and provided to the data processing module. The energy storing unit provides the electrical energy for the load unit. The data processing module receives one of the second splitting signals, converts it into a control signal, and transmits the control signal to the load unit. The load unit operates according to the control signal.

Abstract: A dual-processor system includes a power supply, a temporary memory, a non-volatile memory and two processors. The non-volatile memory stores an initialization program code, a first configuration file corresponding to a first operating system, and a second configuration file corresponding to a second operating system. Compared to the first operating system, the second operating system has a shorter interrupt latency and a shorter thread switching latency. After the power supply starts to supply power, the first processor executes the initialization program code to perform operations of initializing the temporary memory, loading the second configuration file into the temporary memory, notifying the second processor to fetch the second configuration file from the temporary buffer, loading the first configuration rile into the temporary memory and establishing the first operating system according to the first configuration file.

Abstract: A crutch includes a main frame mainly constructed of two spaced posts, wherein each post defines multiple positioning holes. A handgrip includes a main piece and two fasteners. The main piece defines two receiving spaces at its two ends for receiving the posts of the main frame. Each fastener has a positioning stud, a first portion, and a second portion. The first and second portions enclose one post of the main frame and can be operated to move between a first position and a second position. When each fastener is moved to the first position, the positioning stud is inserted into one of the positioning holes, while the first portion is engaged with the main piece. When the fastener is moved to the second position, the positioning stud is clear of the positioning hole, while the fastener is unable to leave the post.
