Abstract: The present invention includes a guided microwave spectroscopy system (1) that eliminates the need for an automatic gain control feature by providing multiple signal processing paths having differing fixed voltage gains. An emitted signal which exits a test chamber (2) containing a material under test is simultaneously amplified by at least a first fixed gain amplifier (4) and a second fixed gain amplifier (7). The output signal of each amplifier is separately digitized and then normalized for further digital signal processing by a computer (13) in order to determine parameters of the material under test which may have variable microwave radiation characteristics that are a function of the frequency of the signal emitted into the test chamber. During the signal processing step a system clock (121) causes the computer to sample only an integral number of complete output signal cycles. A calibration protocol (136-154) is conducted based on laboratory samples of each potential material to be processed by the system (1).

Abstract: A method for monitoring the shape of teeth including: producing a three-dimensional digital model of at least one portion of an arch of the patient or “initial reference model”; acquiring at least one two-dimensional image of the arches, referred to as “updated image”, under actual acquisition conditions; analysing each updated image and producing an updated map relating to a piece of discriminating information; optionally determining rough virtual acquisition conditions that approximate the actual acquisition conditions; searching each updated image for a final reference model corresponding to the shape of the teeth, and optionally to the positioning of the teeth, during the acquisition of the updated image; and comparing the shapes of the initial reference model and of the reference model obtained at the end of the preceding steps, referred to as “final reference model”, in order to determine the deformation and/or the movement of teeth between steps a) and b).

Abstract: Apparatus and methods are described, for detecting the surface topography of a portion of a curved surface of an object. A beam of light is directed toward the surface from a broad angle of incidence with respect to an optical axis of a camera. Light reflected from the surface is received by the camera, via a narrow-angle aperture. One or more darkened regions in the received light are detected, and the surface topography of portion of the surface is detected at least partially in response to the detected darkened regions. Other applications are also described.

Abstract: In some aspects, a device for apportioning granular samples includes a sample feeder defining a conduit, the conduit including a first opening to receive the granular samples and a second opening. The device includes a shuttle operably coupled to the sample feeder to receive the granular samples from the conduit via the second opening. The shuttle is configured to apportion the granular samples to incrementally enter a sample chamber to be analyzed. The device includes an outlet conduit fluidly coupled to the sample chamber and configured to permit the sample chamber to be evacuated.
