Abstract: BONE DENSITOMETER Abstract of Disclosure In an x-ray bone densitometer, special calibration techniques are employed to accomodate variations.  In one aspect, a bone-like calibration material is interposed and the system determines the calibration data from rays passing only through flesh. In another aspect, a rotating device carries the calibration material through the beam.  The specific densitometer shown uses an x-ray tube operated at two different voltages to generate a pencil beam, the energy levels of the x-ray photons being a function of the voltage applied.  An integrating detector is timed to integrate the detected signal of the patient-attenuated beam over each pulse, the signals are converted to digital values and a digital computer converts the set of values produced by the raster scan into a representation of the bone density of the patient, Multiple reference detectors with differing absorbers are used by the system to continuously correct for variation in voltage and current of the x-ray tube. Calibration is accomplished by the digital computer on the basis of passing the pencil beam through known bone-representing substance as the densitometer scans portions of the patient having bone and adjacent portions having only flesh.  A set of detected signals affected by the calibration substance in regions having only flesh is compared by the computer with a set of detected signals unaffected by the calibration material.

Title: Sub-ranging a/d converter with flash converter having balanced input
Inventor: FERNANDES JOHN W
IPC: H03M1/14
Filed: 1988-10-03
Granted: 1992-01-28
Abstract: ABSTRACT         A 12-bit sub-ranging A/D converter which operates through four successive sub-ranging cycles with an 8:1 gain change between the cycles.  The residue signal for each cycle is directed to a four-bit flash converter the output of which sets the latches for corresponding bit-current-sources of a DAC.  The flash converter input circuit com-prises identical residue and reference amplifiers driving symmetrical residue  and reference networks for controlling the flash converter comparators.  The DAC output for each cycle is compared with the analog input signal to produce a corresponding new residue signal.  There are 15 bit-current-sources, three for the first cycle, and four for each of the last three cycles.  The MSB of each group of four bit-current sources is an overlap bit having the same current weighting as the LSB of the preceding group.  Setting of the overlap bit makes it possible to develop a correct output for the DAC for each of the 2nd through 4th cycles without altering bits already determined in previous cycles. The converter provides an optional 5th cycle making possi-ble a 14-bit output or an increased yield of 12-bit con-verters.

Abstract: ABSTRACT OF THE INVENTION     A pivotable shaft supports a plurality of conductor elements.          The conductor elements are pivoted into and out of contact with their associated electrical contacts upon rotation of an over center mechanism so as to selectively make or break an electrical connection.  The conductor elements are freely rotatable within the shaft so as to minimize the effects of arcing on these members.  The pivotable shaft is supported in a housing made of non-conductive material such that the electrical contacts and conductor elements are isolated from the surrounding environment to provide an explosion proof switch.
