Abstract: A technique and device provides absolute skin dosimetry in real time at multiple tissue depths simultaneously. The device uses a phoswich detector which has multiple scintillators embedded at different depths within a non-scintillating material. A digital pulse processor connected to the phoswich detector measures a differential distribution (dN/dH) of count rate N as function of pulse height H for signals from each of the multiple scintillators. A digital processor computes in real time from the differential count-rate distribution for each of multiple scintillators an estimate of an ionizing radiation dose delivered to each of multiple depths of skin tissue corresponding to the multiple scintillators embedded at multiple corresponding depths within the non-scintillating material.

Abstract: A phoswich radiation detector for simultaneous spectroscopy of beta rays and gamma rays includes three scintillators with different decay time characteristics. Two of the three scintillators are used for beta detection and the third scintillator is used for gamma detection. A pulse induced by an interaction of radiation with the detector is digitally analyzed to classify the type of event as beta, gamma, or unknown. A pulse is classified as a beta event if the pulse originated from just the first scintillator alone or from just the first and the second scintillator. A pulse from just the third scintillator is recorded as gamma event. Other pulses are rejected as unknown events.

Abstract: A hydraulic control system for controlling expansion and contraction of a cylinder. The cylinder comprises an extension chamber and a contraction chamber. The hydraulic control system comprises a first servovalve comprising a first pressure supply port and a first pressure discharge port and adapted to selectively communicate the expansion chamber with the first pressure supply port and with the first pressure discharge port. A second servovalve, comprising a second pressure supply port and a second pressure discharge port, is adapted to selectively communicate the contraction chamber with the second pressure supply port and with the second pressure discharge port.
