Abstract: A robotic vehicle, such as an autonomous mobile robot (AMR), is provided, comprising a chassis, a navigation system, and a load engagement portion, a plurality of sensors, including an object detection sensor, and a load interaction system. The AMR is configured to perform a load drop and a load pickup within a zone without using predetermined load pick up and drop off locations within the zone. The AMR can determine where to place a load within the zone based on proximity to another object or physical structure within the zone. A location of the zone on the AMR's route can be trained, but pickup and drop locations within the zone can be untrained and undefined in advance.

Abstract: Provided are a resource management system and method, which can be implemented in the context of autonomously navigating vehicles, such as autonomous mobile robots (AMRs). A route and a graph network are provided, wherein the graph network comprises interconnected nodes representing resources in an environment. The resources include shared spaces and non-shared spaces accessible by the vehicle navigating the route. A resource manager module analyzes the route based on the graph network to determine one or more sets of related shared spaces on the route; applies an ordering algorithm to generate a hierarchy associated with each set of related shared spaces; and, for each set of related shared spaces, generates a set of behaviors to be executed by the vehicle to request access to the set of related shared spaces based on the associated hierarchy.

Abstract: An indicator tab comprising a thermochromic material is mounted in thermal contact with an electrical component in an enclosure. An observation port in a cover of the enclosure is juxtaposed with the indicator tab enabling visual observation of the thermochromic material indicating a temperature of the component. Each indicator tab comprises a visible portion on one end of an arm where the thermochromic material is located and a fastening portion on the other end thermally contacting the component. The indicator tab is composed of a material having a high thermal conductivity to efficiently conduct heat toward the visible portion. In an enclosure where the components are close together, the arm may be composed of a high electrical resistivity material to avoid creating a short circuit with other components. Alternately, in an enclosure where the components are not closely positioned, the arm may be composed of a metallic material.

Abstract: An agitation system including a motor that is capable of measuring the torque output of the motor required to mix a suspension. The motor is attached to an agitator which is placed in a suspension to be measured. The agitator is placed in the suspension and the agitation system is turned on for a period of time. This period determined by the type of agitator used and the characteristics of the suspension. When the suspension is well mixed and the torque measurement on the agitator becomes stable, the agitation system is stopped. The suspension is allowed to sit without agitation for a period of time and the agitation system is started again. After a period of time the agitation system is started and the amount of torque needed to begin turning the agitator is measured.

Abstract: To reduce the amount of additional coding required each time end users request new email notifications, based on a combination of specific field values, a new process for end-user email notifications is used to provide the user or database owner/administrator the ability to create these specific rules more easily. Each time an update is done in the master work flow document, the new process cycles through the filter rules and will provide the relevant email to the end-user. Other embodiments or examples are also discussed.

Abstract: A method for the manufacture of a three-dimensional object includes the steps of forming a mixture that contains a binder and a least one of aluminum or a first aluminum-base alloy into a green composite, removing the binder from said green composite, forming a porous perform structure, reacting the aluminum or first aluminum base alloy with nitrogen to form a rigid and continuous skeleton and infiltrating the porous structure with molten aluminum or second aluminum base alloy to form the three-dimensional object with near theoretical density. The green composite may be formed by an additive process such as computer aided rapid prototyping, for example, selective laser sintering. The method facilitates the rapid manufacture of aluminum components by an inexpensive technique that provides high dimensional stability and high density.
