Abstract: A mouse for controlling a cursor movement speed based on a pressure is provided, which has a simple structure and a fast adjustment speed and can control the cursor movement speed based on the pressure of the mouse. The mouse includes a microprocessor, a pressure detection unit, a movement detection unit and a button detection unit. The pressure detection unit, the movement detection unit and the button detection unit are signal-connected to the microprocessor, respectively. When the movement detection unit detects a movement signal of the mouse, data sent by the mouse is adjusted based on the pressure detected by the pressure detection unit to change the cursor movement speed. The new mouse belongs to the technical field of computer peripherals.

Abstract: An alarm apparatus includes a mobile terminal, a plurality of streetlamps, a server, and a management center. The mobile terminal includes a microprocessor, a display screen, a first GPS positioning module, a battery, an emergency call button, a first GPRS communication module, a first wireless communication module, a first camera, a loudspeaker, and a microphone. The streetlamp includes a central processor, a power supply, a second camera, a mobile device, a second GPS positioning module, a second wireless communication module, and a second GPRS communication module. The caller sends a distress signal to the streetlamp. The streetlamp is automatically illuminated and the direction of the camera is adjusted to the escape direction of the suspect. All streetlamps located on the escape route of the suspect are turned on to capture the escape route of the suspect. The streetlamp sends the information to the management center by means of the server.
