Abstract: A system for a lattice mesh comprises an interface and a processor. The interface is configured to receive a request to join a publish group from a client. The processor is configured to determine a group key; determine whether the client is allowed access to a topic of the publish group; in response to the client being allowed access to the topic of the publish group, provide the group key to the client; publish a group message including metadata; determine whether it is time to rotate the group key; and in response to it being time to rotate the group key, determine a new group key.

Abstract: A system for display and interaction includes an interface and a processor. The interface is configured to receive data from one or more sensors. The processor is configured to convert the data to a common synthetic data space; provide the common synthetic data space for display; and receive a command associated with an object represented in the common synthetic data space. In some embodiments, the processor is coupled to a memory that stores instructions for the processor.

Abstract: A system for a lattice mesh comprises an interface and a processor. The interface is configured to receive a request to register from a host, wherein the request to register includes a key and a set of asset IDs that the host wishes to claim. The processor is configured to sign the key to generate a resource authority (RA) certificate signed key with an RA certificate; update an asset database with the RA certificate signed key; distribute the RA certificate signed host public key through the network; and provide the host with the RA certificate signed key. In some embodiments, the system further comprises a memory that is coupled to the processor and configured to provide the processor with instructions.

Abstract: The control of flexible systems is often difficult due to the exact frequencies of the elastic modes being hard to identify. These flexible modes may change over time, or vary between units of the same system. The variation in the modal dynamics may cause a degradation in performance or even instabilities unless compensated for by the control scheme. Controllers designed for these types of systems use notch filters for mode suppression. However variation in the parameters of the flexible modes may cause the need for wide notch filters. An adaptive scheme is proposed which uses an online estimator based on plant parameterization. The scheme may not use probe signals and may not rely on exact parameter identification of the unknown parameters. Instead it may continuously update itself to cancel the effect of the flexible modes by been able to identify the effect of the modal dynamics on the performance of the system.

Abstract: A graphical user interface for a floral merchandising system. The graphical user interface includes a selection bar having one or more floral product tabs, each floral product tab representing one of a number of floral products. The graphical user interface further includes one or more user-selectable item buttons, each item button corresponding to one of the number of floral products, and one or more windows for displaying information about one of the number of floral products according to a user selection.

Abstract: A unified transport and display mechanism is particularly suited for transporting and displaying buckets and items within buckets. The items include, but are not limited to, flowers or other plant specimens. The mechanism includes a container and a lid for covering the container. The lid includes one or more perforated areas, the removal of which forms one or more corresponding apertures. Each aperture is sized and adapted for receiving an item such as a bucket in a display mode. When received, the bucket extends into the aperture at a level below a top surface of the lid, and partially extends above the lid top surface to allow visual access to the items.
