摘要： The invention is embodied in improvements in calculating discrete Fourier transform (DFT) using recursive digital filtering in a method for determining the velocity of a target located in a medium for vibratory energy. In the method a transmitter electrical signal of prescribed frequency is generated. Coherent vibratory energy, the frequency of which is in fixed relationship with said prescribed frequency, is transmitted into the medium and is directed toward the target. The transmitting is done in recurring pulses of prescribed duration. During range gate intervals each of prescribed duration, the transmitted coherent vibratory energy is received from the medium after its interaction with the target. The vibratory energy which is received during the range gate intervals is converted to a receiver electrical signal. The transmitter and receiver electrical signals are mixed together to obtain a demodulated electrical signal through heterodyning or homodyning. The demodulated electrical signal is digitized and then digitally filtered on a recursive basis to separate it into digitized spectral components in accordance with a discrete Fourier transform procedure. Squaring the absolute value of each of the digitized spectral components generates digital electric signals descriptive of the power spectrum of the interaction of the vibratory energy with said target. After performing a comparative analysis of the digital electric signals descriptive of that power spectrum, the velocity of the target is calculated from the results of the comparative analysis.

摘要： A manually-operated rotary switch apparatus utilizes a rotatable magnet for establishing the dual-polarity outputs of each of a pair of magnetic field sensors, oriented substantially perpendicular to each other. The dual-polarity voltages are processed to approximate the arc tangent of the angle of the knob-rotatable magnetic member, with respect to a reference orientation, to provide digital data output related to the switch position of the manually-rotatable knob.

摘要： An electronic device, such as a digital camera, includes sensors to acquire subject data, such as an electro-optical image, as well as additional sensors to acquire meta-data such as temperature, humidity, the identification of the subject data, and the data and time. The electronic device further includes an image evaluator, to determine the best steganographic method to use to combine the meta-data and the subject data, and a steganographic engine, to combine the meta-data and the subject data in an undetectable manner. In this way, meta-data can be associated with the subject data when the subject data is acquired and in a manner that attaches the meta-data and the subject data without requiring generating and maintaining two, linked data sets.

摘要： A high resolution analog-to-digital (A/D) converter (14) and a pipelined A/D converter are used in a single system so that unknown offset and gain errors of the pipe-lined A/D converter are determined and corrected. Each stage of the pipelined A/D converter includes a flash A/D converter (16), a corresponding digital-to-analog (D/A) converter (18), and a differential amplifier (20) so that, in each stage the output voltage of the D/A converter is subtracted from a sample of the analog input voltage, to constitute the input signal for the next stage. The flash A/D converter of each stage addresses digital words in memory (22) which, when summed by an adder chain (24), constitute the output signal of the system. The flash A/D converter output signals are also supplied to corresponding stages of a shift register (28 or 28') which accumulates the memory address bits. A comparator and finite state machine (26) receives the memory address bits from the shift register and iteratively compares the digital output signals of the pipelined A/D converter and the high resolution A/D converter and corrects the words in memory addressed by the flash A/D converters to improve resolution of the system.
