YAXING LIU. Use of the Thin-Strut FDTD Formalism For the Design of Coils In Biomedical Telemetry Applications. (Under the direction of Dr. Gianluca Lazzi.) For many years, inductively coupled telemetry systems have been designed and used for transcutaneous energy transfer in biomedical applications. But most of these designs are mainly based on steady state circuit analysis. To our knowledge, n...

We propose a notation for specifying event stream abstractions for use in spacecraft telemetry processing. Our work is motivated by the need to quickly process streams with millions of events generated by the Curiosity rover on Mars. The approach builds a hierarchy of event abstractions for telemetry visualization and querying to aid human comprehension. Such abstractions can also be used as in...

With the increasing importance of networked systems for telemetry, there is a need for efficient routing algorithms in aeronautical environments. Unlike traditional mobile networks, the highly dynamic nature of airborne networks results in extremely short-lived paths, especially for multi-hop scenarios thereby necessitating domain-specific protocols. In this paper, we present the detailed desig...

Typical airborne test platforms use multiple telemetry transmit antennas in a top and bottom configuration in order to mitigate signal shadowing during maneuvers on high dynamic platforms. While mitigating one problem, this also creates a co-channel interference problem as the same signal, time delayed with differing amplitude, is sent to both antennas. Space-Time Coding (STC) was developed wit...

The flight software for the on-board Apollo Primary Guidance, Navigation and Control System provides attitude and trajectory control, recursive navigation, targetting, inertial subsystem moding and alignment, prelaunch checkout, crew interaction and telemetry processing for each spacecraft. To develop and flightqualify this complex software package, an all-digital, instruction-by-instruction si...

The System Dynamics Characterization and Controls Laboratory of Sun Microsystems has developed novel continuous system telemetry technology for proactive fault monitoring and “electronic prognostics” capabilities for all types of executing computing platforms. Central to the goal of designing and evaluating prognostic and control systems for enterprise computing platforms is first the ability t...

Blood pressure (BP) was analyzed invasively using the telemetry system in unanesthetized, unrestrained healthy adult mongrel cats. After surgical implantation of a telemetry transmitter, BP was transiently elevated due to the invasive nature of the surgery, but it was gradually decreased. BP was largely stabilized seven to ten days postsurgery. Once BP was settled, systolic, diastolic and mean ...

In this work we show the design and implementation of an efficient telemetry subsystem for Wireless Sensor Networks inside the Vehicle Equipment Bay (VEB) of the ARIANE 5. The telemetry subsystem is utilizing infrared data communication and consists of various smart sensor chips such as temperature sensor, humidity sensor, visible light intensity sensor, infrared light sensor, acceleration sens...

Using the telemetry system, we measured the blood pressure (BP) invasively in seven adult mongrels while unanesthetized and unbound. Post-operative BP after implanting the telemetry BP transmitter showed temporarily high values due to the invasive nature of the surgery. It was, however, observed that BP gradually decreased thereafter, and showed settled trends from the eighth day post-operative...
