摘要： The present invention relates to a detecting device for detecting a blood count parameter in a blood vessel. The detecting device comprises a signal generator, which is designed to generate a calibration measurement signal, wherein the calibration measurement signal comprises a superimposition of a first excitation signal and a second excitation signal, wherein the first excitation signal has a higher frequency than the second excitation signal and/or the second excitation signal is a direct signal and/or wherein the second excitation signal has a higher power than the first excitation signal; a transceiver arrangement which is designed to emit the calibration measurement signal towards the blood vessel and to receive a first system response signal in response to the emission of the calibration signal; wherein the transceiver arrangement is designed to emit a third excitation signal directed towards the blood vessel and to receive a second system response signal in response to the emission of the third excitation signal; and a processor which is designed to link the first system response signal and the second system response signal in order to obtain a measurement signal for determining the blood count parameter.

摘要： A security check method includes: pre-creating at least four concurrently operating threads, one thread being responsible for movement control and data acquisition, one thread being responsible for imaging processing, one thread being responsible for interface displaying, and one thread being responsible for target detection and recognition; then the four concurrently operating threads divide original echo data of a human body to be checked into data of a plurality of adjacent overlapped azimuthal segments during data processing and perform individual processing on the data of each azimuthal segment. The security check system includes a thread creating unit, a first thread parallel unit, a second thread parallel unit, a third thread parallel unit, a fourth thread parallel unit, and a thread loop control unit. Because subsequent data processing is not required to be performed after the acquisition of all data is completed, the time for a security check process is reduced.

摘要： An automated medical diagnostic system includes antennas, transmitter, receiver, and a processor-based device or system. Excitations signals are transmitted into bodily tissue at each of a plurality of discrete frequencies (e.g., steps of 1 MHz from 300 MHz to 2500 MHz) or unequal steps. The response signals are received and analyzed against the excitation signals at each of a number of the frequencies, for example determining gain/loss due to passage through bodily tissue. The results are analyzed for patterns indicative of a presence or absence of an abnormal condition, and results presented.

摘要： Radiometric systems may comprise a radiometer, an antenna and a processor communicatively coupled together. The processor may provide a contact-focused output based on filtering or other processing of a raw radiometric output signal. The contact-focused output may facilitate determination of whether contact has been achieved and/or assessment of contact. A miniaturized reflectometer may be configured to determine an amount of reflected power from the antenna. The processor may be configured to determine a reflection coefficient of the reflected power determined by the reflectometer and to identify tissue type based on the reflection coefficient. Systems and methods for facilitating deeper temperature measurements of a radiometer are described.
