An electronic timepiece includes a detection axis calibration unit configured to execute first calibration processing of calibrating an axial direction and second calibration processing of calibrating a direction along a third detection axis, the second calibrating processing being executed after first calibration processing, a mode setting unit configured to set a first measurement mode when second calibration processing is not completed after completion of the first calibration processing, and set a second measurement mode when the second calibration processing is completed, a first azimuth calculation unit configured to calculate an azimuth, based on detected values of a three-axis magnetic sensor in two axial directions, when the first measurement mode is set, and a second azimuth calculation unit configured to calculate an azimuth, based on detected values of the three-axis magnetic sensor in three axial directions and a detected value of a inclination sensor, when the second measurement mode is set.

Systems and methods for modifying display unit operations based on orientation are provided. A controller receives orientation data from an orientation detection device and commands operations of a thermal management system based, at least in part, on the received orientation data. A solar angle relative to the electronic display may be determined based on a location, a date, a time, and the orientation data. Cooling may be modified based on solar angle relative to the electronic display. The orientation data may be used to check installation, determine damage, or position of display unit components.

A position indicator includes a housing and a first electrode and a second electrode disposed on a side of one end of the housing and a signal generating circuit which, in operation, generates a signal supplied to at least the first electrode. A capacitive interaction between the first electrode and a sensor of a position detecting device formed through supply of the signal to the first electrode. The second electrode surrounds the first electrode and the first electrode is partially exposed from the second electrode in an axial direction of the housing. The position indicator includes a signal transmission control circuit that is coupled to the second electrode and that, in operation, controls the second electrode to change the capacitive interaction between the first electrode and the sensor formed through supply of the signal from the signal generating circuit to the first electrode.

A laser level containing a housing, an electronic tilt sensor located in the housing; a controller to which the electronic tilt sensor is connected, and a laser module. The controller is communicable with a first display device and a second display device. The laser line is adapted to project a straight ground laser line on a flat surface. The electronic tilt sensor is adapted to detect a tilt of the laser level and provide a measurement signal to the controller. The controller is adapted to provide a display signal to the first and second display devices to display information about the tilt. By using an electronic tilt sensor, the laser level can provide accurate indicate of the tilt of the device and also allows such tilt information to be processed further.

Disclosed are a control method of a mobile robot, a mobile robot, and a storage medium. The method includes: when distance information obtained by a laser radar has an effective distance change, predicting an inclination angle of a forward road section relative to a current road surface where the mobile robot is currently located; determining a slope of the forward road section based on the inclination angle and a pitch angle; controlling movement of the mobile robot based on the slope and a result of comparison between the slope and a slope threshold preset by the mobile robot; and marking the forward road section as a slope area on a slope map, where the slope map is used to control, based on the slope area when the mobile robot passes by the slope area, the mobile robot to send climbing warning information.

A tilt indicator includes a housing having a face member and a back member. A movable mass member is disposed within the housing between the face member and the back member. A first encoded indicium is disposed on the mass member, and a second encoded indicium is located on the back member. In response to the tilt indicator being subjected to a tilt event exceeding a threshold, the mass member moves from a first position to a second position.
