Abstract: A home position indicator that enhances the functionality of an incremental encoder with characteristics of an absolute encoder includes a target flag having a plurality of marks. In one embodiment, pairs of adjacent marks of the plurality of marks define sections between each adjacent pair of marks of the plurality of marks. Each section has a width, wherein one of the sections has a width greater than a width of another of the sections. A sensor sequentially senses two adjacent marks of said plurality of marks to determine a width of the section defined between the two adjacent marks.

Abstract: As an autonomously guided industrial vehicle travels through a facility images of the adjacent environment are acquired, by either a still camera or a video camera. An image file containing a plurality of the images is stored onboard the vehicle. During that travel, the location of the vehicle is determined. Upon occurrence of a predefined incident, such as encountering an obstacle or impacting an object, an incident message is transmitted wirelessly from the vehicle to a remote management computer. The incident message contains an indication of the type of incident, an indication of a location of the vehicle, and the plurality of the images. The remote management computer responds to the incident message by providing a notification about the incident to one or more persons. The contents of the incident message enables the person notified to take corrective action.
