Systems, methods, and other embodiments described herein relate to guiding a user travelling along a path. In one embodiment, a method includes predicting, by a processor, a behavior of a user based on at least sensor data received by the processor. The user is travelling on a pedestrian path. The method further includes, in response to a predicted behavior, controlling a guide, by the processor, to output the guide along the pedestrian path to direct the user.

This invention relates to the field of industrial safety monitoring equipment technology, and discloses an automatic overheat detection and alarm device for thermal power plants based on the principle of thermal expansion. The device includes a housing and a bimetallic strip. A vertical rod is slidably connected to the middle of the housing, and a horizontal plate is fixedly connected to the top of the vertical rod. An engaging assembly is disposed inside the housing, and the bimetallic strip is located in the middle of the engaging assembly. The bottom of the vertical rod contacts the top of the bimetallic strip. A visual warning assembly is disposed in the middle of the vertical rod, and an auditory warning assembly is disposed on the rear inner wall of the housing. The bimetallic strip deforms due to heat, pushing the vertical rod upwards, which causes a stop block to release the lock on the spring-loaded gear set, thereby releasing the stored energy of the spring to drive a hammer to continuously strike the warning bell. Simultaneously, a warning sign at the top of the vertical rod extends out of the housing, providing continuous audible and visual signals when overheating occurs, ensuring timely detection of hazards in the noisy environment of a thermal power plant.

The utility model discloses a central water outlet high-pressure pump with a pressure maintaining device for a machine tool, which relates to the technical field of high-pressure pumps and comprises a high-pressure pump body, a pressure relief pipe and a rotating shaft extending to the outer side of the pressure relief pipe, an impeller is mounted on the portion, located on the outer side of the pressure relief pipe, of the rotating shaft, and an elastic connecting assembly is mounted at the top end of the rotating shaft. A clicker is mounted at a pipe orifice on one side, close to the rotating shaft, of the pressure relief pipe. Through the arrangement of the impeller, a worker can know the pressure relief condition by observing the rotating speed of the impeller, through the arrangement of the elastic connecting assembly and the clicker, when the pressure relief amount of the high-pressure pump body is out of a preset range, airflow enables the impeller to rotate at a high speed, and the rotating shaft drives the elastic connecting assembly to rotate at a high speed; the elastic connecting assembly extends under the action of overlarge centrifugal force, the elongated elastic connecting assembly knocks the clicker to make a sound and give a noise alarm in the rotating process, even if sensor equipment in the prior art breaks down, the elastic connecting assembly can be matched with the clicker to give an alarm, and the alarm effect is more stable and reliable.
