摘要： Methods and apparatus for atmospheric sounding using acoustic chirps are disclosed, the transmitted and echo chirps being compared in a mixer that yields frequency sums and differences. Preferably, the mixing is performed as a complex multiplication in the Fourier domain. In one system (1) a signal generator (5) such as a PC sound card drives a loudspeaker (3) that serves as a transmitter and echo pulses are detedcted by a microphone (4) that serves as a receiver. Chirps transmitted by the loudspeaker (3) travel by different paths (7a and 7b) due to reflection from TILS or thermal inversion layers (2a and 2b) at different altitudes. The transmitted and echo chirp signals are compared in a mixer (6) from which various outputs (8 and 9) can be generated. One output (8) might be the magnitude of the difference between the transmitted and echo chirp tones, instant by instant, which is indicative of the altitudes of the respective TILs. The other output (9) might be the phase shift in an echo tone with transit time, which is indicative of vertical wind velocity at different altitudes. Such sounding methods and apparatus are useful for weather research, prediction of plume dispersal and the design of microwave links to minimize multipath fading.

摘要： A system for carrying out surgery on a bodily structure (e.g., breast and liver) with greater precision, accuracy, comfort and minimal invasiveness. A 3-dimensional tracking and imaging system (1000) is used to obtain an accurate position of an instrument as it is maneuvered by an operator, and to mark a location on the subject bodily structure. The system is particularly advantageous for surgical procedures for biopsying and destroying tumors in bodily structures which are easily deformable.

摘要： A method for carrying out a medical procedure using a 3-D tracking and imaging system (1600). A surgical instrument, such as a catheter, probe, sensor, needle or the like is inserted into a living being, and the position of the surgical instrument is tracked as it moves through a medium in a bodily structure. The location of the surgical instrument relative to its immediate surroundings is displayed to improve a physician's ability to precisely position the surgical instrument. The medical procedures include removal of an obstruction from the circulatory system, a biopsy, amniocentesis, brain surgery, measurement of cervical dilation, evaluation of knee stability, assessment of myocardial contractibility, eye surgery, prostate surgery and trans-myocardial revascularization (TMR). In addition, the method of the present invention also finds use in connection with the generation of 2-D echo planes.

摘要： A system for tracking the position of each of a plurality of labelled objects in a specified environment by determining the transit time of ultrasound signals transmitted from a transmitter on each labelled object, to a plurality of ultrasound receivers positioned at fixed points in or around the specified environment, and computing therefrom the distance of the transmitter from the receivers. The ultrasound transmissions are initiated by radio signals from a master transmitter and each of the objects includes a radio receiver adapted to respond to the radio transmissions to initiate a burst of ultrasound. In order to allow the system to adapt to different numbers of transponder-transmitters and differing demands for service (e.g. frequency of position determination per transponder-transmitter), a coordinating control system is provided for determining the order in which the object mounted transponder-transmitters are to be triggered by the radio transmissions, in response to updatable information relating to the objects and related service demands.

摘要： Techniques and apparatuses are described that implement face authentication anti- spoofing using ultrasound. In particular, a face-authentication system (202) uses ultrasound to distinguish between a real human face and a presentation attack that uses instruments to present a version of a human face. The face-authentication system (202) includes or communicates with an ultrasonic sensor (216), which can detect a presentation attack and notify the face-authentication system (202). In general, the ultrasonic sensor (216) uses power-spectra to evaluate an amount of variance observed over time within at least one receive channel. In this way, the ultrasonic sensor (216) can prevent unauthorized actors from using the presentation attack to gain access to a user's account or information.

摘要： Techniques and apparatuses are described that implement face authentication anti-spoofing using interferometry-based coherence. In particular, a face-authentication system (202) uses ultrasound to distinguish between a real human face and a presentation attack that uses instruments to present a version of a human face. The face-authentication system (202) includes or communicates with an ultrasonic sensor (216), which can detect a presentation attack and notify the face-authentication system (202). In general, the ultrasonic sensor (216) uses interferometry to evaluate an amount of coherence (or similarity) between reflections observed by two or more transducers. In this way, the ultrasonic sensor (216) can prevent unauthorized actors from using the presentation attack to gain access to a user's account or information.
