A laser level assembly is provided. Various methods of managing communications between laser levels and detectors are provided. In one or more methods, upon receiving a selection of a communication channel the laser level emits a laser with certain characteristics, such as by adjusting the rotation speed, rotational direction, and/or emitting the laser in a repeating on/off pattern.

A posture estimation method includes calculating a posture change amount of an object based on an output of an angular velocity sensor, predicting posture information of the object by using the posture change amount, adjusting error information in a manner of determining whether or not the output of the angular velocity sensor is within an effective range and, when it is determined that the output of the angular velocity sensor is not within the effective range, increasing a posture error component in error information and reducing a correlation component between the posture error component and an error component other than the posture error component in the error information, and correcting the predicted posture information of the object based on the error information.

An expandable level includes a pair of extension bodies, with at least one of the extension bodies carrying a level indicator. Each extension body includes a carriage with a carriage cavity, the carriage cavities aligned with each other and having a pair of exterior top surfaces separated by the carriage cavity. A rail is slidably received in both carriage cavities and has a body surface that remains substantially flush with the exterior top surfaces when the pair of extension bodies are adjacent one another and when the pair of extension bodies are spaced apart from one another.
