A system and method for performing pilot tone based timing recovery in a communication system using the discrete multi-tone (DMT) modulation. In DMT modulation, interference is introduced to the phase of the pilot tone in the transmitter due to the cyclic prefix. Broadly, a receiver is configured to detect and apply a phase offset to the pilot tone in a phase locked-loop upon recognition of far-end signal segments during transceiver initialization. The output of the phase locked-loop is then used to control the timing of the analog-to-digital (A/D) and digital-to-analog (D/A) conversions. In alternative embodiments, the receiver is configured to detect and remove the cyclic prefix from the far-end signal either prior to, or after, time-domain equalization. In a similar manner, the resulting signal stream is applied to the input of the timing recovery phase locked-loop (PLL). The output of the PLL is used to control the timing of the A/D and D/A converters. In a further alternative embodiment, a phase error on the pilot tone is estimated in the frequency domain. The phase error is then applied to the input of a modified timing recovery PLL to reduce phase interference on the pilot tone.

The invention relates to a designing method for a guidance law applicable to the vertical recovery phase of a rocket. The designing method comprises the following steps: acquiring the full-distance standard trajectory of the rocket; according to the full-distance standard trajectory, acquiring the latitude and longitude of a target point, the motion parameters of the rocket at the starting point of an aerodynamic deceleration phase, and the latitude and longitude of a point below the rocket, and constructing an auxiliary coordinate system; based on the auxiliary coordinate system, additionallysetting terminal angular constraints on the basis of a proportional guidance process so as to obtain a biased proportional guidance law; and applying the biased proportional guidance law in the aerodynamic deceleration phase and applying the biased proportional guidance law with an additional main power deceleration algorithm in a vertical descending phase. The improved biased proportional guidance method in the invention can effectively solve problems in guidance control under the condition of multiple constraints by location, velocity and attitude during rocket recovery; the guidance law for a vertical landing phase employs aerodynamic deceleration and tail-phase short-time main-power deceleration, so no impact is exerted on the carrying capacity of the rocket in an in-orbit flying phase; and at the same time, proportional guidance has better adaptability to various non-guidance deviations.

Systems and methods are presented that enable a legged robot to maintain its balance when subjected to an unexpected force. In the reflex phase, the robot withstands the immediate effect of the force by yielding to it. In one embodiment, during the reflex phase, the control system determines an instruction that will cause the robot to perform a movement that generates a negative rate of change of the robot's angular momentum at its centroid in a magnitude large enough to compensate for the destabilizing effect of the force. In the recovery phase, the robot recovers its posture after having moved during the reflex phase. In one embodiment, the robot returns to a statically stable upright posture that maximizes the robot's potential energy. In one embodiment, during the recovery phase, the control system determines an instruction that will cause the robot to perform a movement that increases its potential energy.

The invention comprises a charged particle cancer therapy system or synchrotron system using a single power supply electrically connected to a plurality of magnet sections to provide a uniform current to a plurality of magnets at a given period in time. Optionally, one or more switches introduce a corresponding one or more resistors into a circuit linking the power supply to a magnet or an inductor during an applied power recovery phase between acceleration cycles of the synchrotron, which reduces time of reduction in power from an active applied power to a power suitable for use with a subsequent injection of charged particles into the synchrotron.

The two forces used are gravity and the atmospheric pressure. Gravity initiates the power phase by causing the water to fall from the elevated sealed water tank 10 to turn the turbine 32. The water lowers to 33.95 feet above ground level within the sealed water tank 10. A vacuum forms above the water. The water flows from the turbine into the elevated open water tank 46 to the level whereby its water outlet valve 26B opens. This affords a passage back into the elevated sealed water tank 10, through the check valve 40 and the manual shut-off valve 42. This initiates the recovery phase. The atmospheric pressure of 14.7 psi on the elevated open water tank 46 forces the water back into the sealed water tank 10 to relieve the vacuum. This pressure is capable to move the water up to 33.95 feet. Here it has only to move it up to 26.95 feet, realizing a 20.6 percent reserve force. With the water level again attaining maximum height in the sealed water tank 10, it is again released to repeat the cycle.

A high-frequency DC to DC converter comprising n transient converter circuits (1, 2 . . . n) operating in parallel. The converter has constant transfer characteristics, and the transient converter circuits are operated phase-shifted by 360°/n and with interleaved duty cycles, which results in a continuous energy transfer through the circuit. The circuit is also soft-switched, with very low switching losses. In particular, the active semiconductors only switch off a relatively small magnetization current, during a recovery phase which can last as long as (n−1)/n of the switching phase period.

A method for monitoring the depth of anesthesia is provided for detecting the conscious state of one being anesthetized in the recovery phase or induction phase of anesthesia course in order to facilitate an anesthesiologist to predict exactly the dosage of an anesthetic required. At first, an original electroencephalogram (EEG) is taken from one being tested. Then, the original electroencephalogram is analyzed by approximate entropy to obtain its approximate entropy value. Next, the approximate entropy value is multiplied by 1000/17, and the corrected value is assumed as the predicted value of depth of anesthesia. The predicted value of depth of anesthesia represents degree of the conscious state or the depth of anesthesia for the one being tested. The higher the predicted depth of anesthesia value, the more conscious the one being tested is, i.e., in a shallower depth of anesthesia. On the other hand, the lower the predicted depth of anesthesia value, the less conscious the one being tested is, i.e., in a deeper depth of anesthesia.
