NetAcquire Pub Sub Example Code

For the ultimate in publish/subscribe drag-and-drop display without programming, see MissionView.

NetAcquire Publish/Subscribe in combination with NetAcquire server decommutation provides the ability to develop entire telemetry applications using drag-and-drop with little or no programming. This example describes how easy it is to combine these NetAcquire system components and to utilize them within a Java application. The example uses WebGain VisualCaf, a popular Java development environment.

The NetAcquire server decommutation component provides an efficient, configurable, decommutation capability to incoming telemetry data streams. One aspect of configuring the decommutation component relates to providing a decommutation “map.” The NetAcquire Java “Telemetry Map Editor” applet is used to configure decommutation maps. This is where individual telemetry measurements are specified (see NetAcquire Decommutation). With NetAcquire Publish/Subscribe all active decommutation map telemetry measurements are automatically available to subscribing clients. In this example the telemetry measurement named “Solar Panel” is configured in the “Test1” telemetry decommutation map.

The example applet is constructed in a similar way as the Drag-and-Drop Example. However, in this example the “SubscriptionVIBAdapter” JavaBean is used instead of the “SubscriptionDataEventAdapter” JavaBean. This JavaBean is used to connect NetAcquire Publish/Subscribe subscriptions to third-party JavaBean display widgets. The icon just below the grid panel in the Form Designer represents the Subscription object. The “SubscriptionName” property is used to specify the “Solar Panel” telemetry measurement that is to be displayed.

The Meter widget is used to display values from the Solar Panel telemetry measurement. Incoming subscription values for this measurement will be represented by the Meter.

The VisualCaf Interaction Wizard is used to connect the Subscription object to the Meter object. The first wizard dialog box identifies the types of events that the Subscription object can send (a ValueChanged event).

The next wizard dialog box is used to specify the action to take after sending this event. In this example the event is sent to the Meter component’s “valueChanged()” method.

After the Interaction Wizard completes a line connects the source component to the destination component indicating the interaction relationship.

This represents an end-to-end NetAcquire Publish/Subscribe telemetry application. When it is run “Solar Panel” telemetry measurement values will be displayed in the Meter.

Preston Hauck

President, Chief Technology Officer

Preston Hauck founded NetAcquire in 1993 with the goal of providing computer communications and processing systems that seamlessly operate with real-time performance over distributed networks.

During the early years of NetAcquire, Preston took a hands-on role in developing new products. He remains enthusiastically involved in helping customers solve complex real-world challenges.

As the company grew, Preston leveraged his information systems background to create tools that could automate business processes, increasing company efficiency, responsiveness, and scalability. In his current role, Preston oversees new product direction, manages company growth,works directly with clients and the engineering team on projects that call for his applications design expertise.

Prior to founding NetAcquire, Preston served as vice president of software engineering for Microstar Laboratories, a provider of PC-based test and measurement products. During his tenure, he helped the company grow tenfold in both revenue and employees. Preston developed an innovative real-time operating system from the ground-up, plus a data processing engine that powered all of Microstar's products for more than two decades.

Preston holds a bachelor's degree in computer science, graduating first in his class in 1984 from the University of British Columbia.  He was granted a U.S. patent for developing a novel approach to initialize one processor from another in a multi-processor system. He has published a number of papers on real-time computer systems and regularly teaches networked telemetry processing classes.

Preston was born in Canada. After many years living in Washington State, he proudly became a naturalized U.S. citizen in 2003. He enjoys traveling, reading, photography, basketball, skiing, and movies with his wife Colleen and their two children.

John Bono

Engineering Vice President

John Bono, a Seattle area native, graduated summa cum laude with a Bachelor of Science in Electrical Engineering from the University of Washington.  John started his career with Boeing Aerospace Company, working in a variety of roles. He received personal recognition from Boeing’s CEO for his contributions to 767 avionics.  John designed hardware and firmware for a Mil-Std-1553 bus interface and was the hardware lead and system designer for a B-1B flight simulator’s computer generated imagery display.  After Boeing, John joined Advanced Technology Laboratories (ATL) as a signal processing engineer. He was promoted to the role of ultrasound system architect before becoming the software and systems lead for an image storage and network transport system. During John’s tenure at ATL, he received a Technical Fellow award, became a member of the Senior Technical Staff, and had a role in ATL’s achievement of ISO 9001 certification.  

When John joined the rapidly growing NetAcquire Corporation in 2001, his “big company” experience was leveraged to enhance configuration management and quality systems and processes. He soon became the Management Representative for the company’s AS 9100 certification efforts.  

Today, John is involved in the system, hardware, and firmware design of virtually every system NetAcquire ships.  While the majority of these systems are customer-specified configurations of NetAcquire COTS hardware and software modules, many other systems are rack-sized, challenging configurations involving complex interchanges of information in all forms.  The NetAcquire motto of “connect anything to anything” is John’s daily mission; he knows that, when applied to real-time systems, there will be a continuous stream of interesting problems to solve and challenges to conquer to best meet the needs of his customers and their mission critical projects around the world.

Steve Proudlock

Sales Vice President

For many NetAcquire customers, Steve is the initial face and voice of the company. While he has a desk at the company headquarters in Kirkland, Washington, quite often he’s in the air, flying to meet customers, discuss projects and set solutions into motion.

Steve joined NetAcquire in the summer of 2001. He sees his principal role as being the customer’s advocate. Steve thrives on opportunities to work on-site with NetAcquire customers to see first-hand the tasks and challenges they face.

In 2002, Steve joined the volunteer organizing committee for the International Telemetering Conference; he serves on the committee to this day. Steve also supports and participates in the meetings and industry standards efforts of several Range Commanders Council (RCC) committees.

Steve is an Army Veteran, having served in locations around the world in military law enforcement and personal protection roles. After graduating Pre Law from Central Washington University, he began a sales career in retail consumer electronics. The career choice was inspired by his favorite uncle, Ken Cartwright, a career tire salesman at Sears. Ken taught Steve the foundation principles of professional salesmanship: “Say what you are going to do, and then do it,” and “Get to know someone by showing sincere interest and earning their trust”.  

Steve’s Microsoft and Cisco certifications help him better understand the technical aspects of test range telemetry. While Steve is well versed in all aspects of NetAcquire technology today, he still learns something new on a daily basis from his colleagues.

Steve is a Seattle area native who enthusiastically gives his time and resources to a local charity dedicated to supporting foster children and their families.
