Bridging data distributed service (DDS) domains in a networked system based on discovery data is provided. Each DDS domain includes DDS software applications capable of publishing data and subscribing to data. A DDS domain bridge is communicatively coupled with the DDS software applications of both DDS domains. The DDS domain bridge monitors discovery data provided by the DDS software applications for a topic name, a topic type, and/or QoS properties. The DDS domain bridge includes creation rules and enabling rules controlling input/output DDS dataflow objects. Based on the state of the DDS dataflow objects set by the rules, uni- or bi-directional DDS dataflow is established between the input and output DDS dataflow objects enabling data propagation between DDS software applications of DDS domains.

A method for reducing a number of copies required to send a data sample with a Data Distribution Service (DDS) type in a system using an Object Management Group (OMG) Data Distribution Service (DDS) and a Real-Time Publish Subscribe (RTPS) protocol is provided. Key to the invention is the definition/creation of a memory representation of the data samples for the DDS type that is equal to the network representation of the data samples for the DDS type. Sending of data samples to the DataReader is accomplished without making a serialization copy of the data samples, and for the receiving the data samples from the DataWriter is accomplished without making a deserialization copy of the data samples. Further, a method is provided for accessing to a network representation of data samples with a DDS type in a system using an OMG DDS and a RTPS protocol.

A bidirectional conversion method is provided between a memory representation and a network representation of data samples associated with a DDS type in a system using an Object Management Group DDS and a Real-Time Publish Subscribe (RTPS) protocol that is more potent, maintainable, and with a smaller footprint. A first conversion recipe is generated using a type description and a language binding information that transforms any data sample associated with the type description from a first memory representation to a network representation, and this first conversion recipe is generated only once. A second conversion recipe is generated using a type description and language binding information that transforms any data sample associated with the type description from the network representation to a second memory representation, and this second conversion recipe is generated only once. Both generated first and second conversion recipes are then executed on all data samples.

Adaptive tuning techniques are provided for data communications in an Object Management Group (OMG) Real-Time Publish Subscribe (RTPS) Protocol operable over a communication network to provide good throughput/latency tradeoff as well as efficient bandwidth utilization. With this invention, latency under high throughput conditions can be reduced several times compared with the latency obtained with traditional non-adaptive approaches.

A method of and device for generating an identifiable signal to facilitate an order picking process are disclosed. The method and device can be used on an order picking station having containers with items to be picked. In some embodiments, the station has multiple shelves having signal generating devices coupled with each of the containers on the shelves. The device takes the information of the items to be picked and generate identifiable signals, such that the device provides visual effects to facilitate workers' picking and gathering efficiency.
