Rao et al. [140] described a study using a commercial pH sensitive radio-telemetry capsule (RTC) to evaluate small bowel and colonic transit time in athletes with gastrointestinal symptoms. The RTC (type 7006 Remote Control Systems, London, UK) consists of a glass electrode with an integral reference cap and battery. RF transmissions from the capsule are detected by a solid-state receiver worn on the belt of the patient. The recorder samples the pH from the capsule at 6 second intervals for a period of 24 hours. They used pH changes as an indication of the pH capsule s movement. A sharp rise in pH from around pH 2 to pH 6 indicates that the capsule has moved into the duodenum from the stomach. Then the pH progressively rises to a plateau around pH 8, which indicates that the capsule has moved into the terminal ileum. Another commercially available wireless pH sensor (Bravo) from Medtronic Inc. has been used to measure esophageal pH for a period of 48 hours and it will be discussed later.

Five continuous ambient air monitoring stations are indicated in Figure 6. At one minute intervals data on these parameters are transmitted by radio telemetry or land line to a minicomputer in the Operations Laboratory. Data manipulation is performed by the minicomputer and all data are transmitted to a large computer in Edmonton on a daily basis. In addition to these five stations, the monitoring network contains 40 static ("Candle") stations. The location of these stations are also given in Figure 6. The static stations have been in operation since May, 1977, one year before start-up, and provide monthly information on total sulphation and hydrogen sulphide. All data collected from the network are summarized in a prescribed format and submitted to Alberta Environment on a monthly and yearly basis. 

Remote control units (RCUs). These components are used to implement basic control functions such as PID control. Some RCUs may be configured to acquire or supply set points to single-loop controllers. Radio telemetry (wireless) may be installed to communicate with MUX units located at great distances.

Vaginal electrodes have been used in studies of reproductive function by Burr et al (1935), Rock et al (1937), and Parsons et al (1958). Techniques reported to date are rather crude and the subject must be essentially immobile. It is suggested that a conforming cylinder or pessary electrode be used in conjunction with a radio telemetry system. Such a system for studies of ovarian function is being developed by Ferris and Weeks (University of Wyoming). With this system, the subject will have complete mobility.

In some situations it is possible to mount probes on the impeller or shaft itself. In these situations, the signal from the probe has to be transmitted either by radio-telemetry equipment or through slip rings on the shaft. 

Generally, there are three types of instruments used to detect ordnance cesium vapor magnetometers, radio telemetry (common metal detectors), and pulse induction units. For many years, none could reliably distinguish between metal debris and ordnance items. Even size is difficult to tell because the signal is faint on a smaller, closer object and faint on a larger, deeper object.
