A cellular radio communication system is provided for transmitting data over a plurality of transmission links. The system includes means for generating a modulated signal by applying a constant amplitude envelope modulation scheme to data to be transmitted across poor quality transmission links and amplifier means for non-linearly amplifying the modulated signal. The system can additionally include means for generating a second modulated signal by applying an amplitude dependent modulation scheme to data to be transmitted across higher quality transmission links and amplifier means for linearly amplifying the second modulated signal. Using a constant amplitude envelope modulation scheme, such as GMSK or MLCAM for poorer quality links means that for these links signals can be amplifier non-linearly at higher gains.

Method and apparatus for detecting possible interference in a neurological signal received from a monitoring element of a medical device system. The monitoring element monitors a condition or a symptom of a nervous system disorder being treated and provides a neurological signal to the medical device system for purposes of providing closed-loop feedback control. The system analyzes various parameters of the received signal by taking instantaneous measurements of data points in moving window and thereby determining whether the signal is of poor quality. If the signal is of determined poor quality, it is removed from consideration in the closed-loop feedback control system until it is determined that the signal quality has sufficiently been restored.

A retaining element system is provided that improves face stability in poorer quality soils that are not suited to conventional soil nailing. The method includes inserting retaining elements substantially vertically into an earthen mass to shore the face of an excavation. The earthen mass can be any material or combination of materials, such as soil, clay or rock that requires excavation for the installation of a shoring wall.

A communications system is tested to simulate a realistic conversation. A first measurement device make a call, through the system it is testing, to a second measurement device and the two devices converse using predetermined speech generated dynamically by each device in response to the signals received from the other, to simulate aspects of conversation over non-perfect communications system link. The progress of the conversation will therefore take different courses according to the quality of the link. For example, if an expected signal is detected by one device, it transmits an appropriate predetermined response to the other device. However, if the expected signal is corrupted, or not received at all, different predetermined responses (or no response at all) are transmitted to the other device. This in turn may cause the other device to repeat the original signal. Because all the responses, including those to poor quality signals, are predetermined, each device can readily determine the quality of the signals received, because each signal received by one device form the other must be one of a limited number of possible responses to the last transmission made by the one device to the other. The devices perform measurements on the sounds they receive from each other, and monitor the progress of the conversation to compute parameters describing aspects of the received signal quality.

The characteristic of the heavy oil obtained by hydrotreating after the mild catalytic conversion of the poor-quality raw oil is significantly improved, thereby significantly increasing light oil, reducing dry gas, reducing the yield of oil slurry and realizing the high-efficient utilization of petroleum resources.
