Abstract:
A method and a machine for balancing vehicle wheels with weights (18), the method comprising stages of: using a video camera (5, 6, 206) to frame a portion of a surface of a hub (101) of a wheel on which a weight (18) is to be applied, locating, in images of the hub (101) taken by the camera (5, 6, 206), at least a balancing plane (E1, E2) which is perpendicular to a rotation axis (A) of the wheel, piloting at least a pick-up device (8, 9, 209) such as to direct the at least a pick-up device (8, 9, 209) onto a point (P1, P2) of the hub (101) belonging to the balancing plane (E1, E2), detecting, by means of the pick-up device (8, 9, 209) characteristic geometric parameters of the hub (101) at the balancing plane (E1, E2), measuring an imbalance of the wheel, calculating, by means of an electronic calculator (4, 204) an entity of at least a weight (18) to be applied to the hub (101) at the balancing plane (E1, E2), and also calculating an angular position (T1, T2) of the weight (18) in the balancing plane (E1, E2).
Abstract:
A portable device for the quality control of vegetal products comprising a power supply (7) intended for powering a circular crown of lighting lamps (41) at the centre of which there is arranged the receiving objective of a spectrometer (45) provided with means (431) adapted for resting on the product to be checked, said spectrometer (45) being associated to a microprocessor (11) which provides the measurement data on display means (12); according to the invention, the lamps (41) are permanently powered, and in stand-by, at a reduced voltage (70), lower than the nominal voltage (71) delivered by the power supply (7), and instantaneously at the nominal voltage (71 supplied by the power supply (7) through a power circuit (8) whose activation is commanded and controlled by the microprocessor (11) in response to an activation signal generated by a button (10).
Abstract:
A borescope includes a housing extending from a first end toward a second end, the housing including a first transparent viewing section extending circumferentially around a longitudinal axis of the housing and defining an exterior of a portion of the housing; a first imaging assembly configured to rotate about the longitudinal axis of the housing, and also pivot relative to the longitudinal axis of the housing; and a second imaging assembly disposed within the housing, the second imaging assembly being configured to rotate about the longitudinal axis of the housing, wherein the second imaging assembly is configured to visualize a field of view exterior of the housing through the first transparent viewing section.
Abstract:
A method and system for inspecting a manufactured part at an inspection station are provided. A supported part is rotated about a measurement axis so that the part moves at predetermined angular increments during at least one rotational scan. A backside beam of collimated radiation is directed at and is occluded by the supported part at each of a first plurality of consecutive increments of movement to create a stream of unobstructed portions of the backside beam in rapid succession passing by and not blocked by the supported part. A frontside beam of radiation is directed at and is reflected by the supported part at each of a second plurality of consecutive increments of movement to create a stream of reflected portions of the frontside beam in rapid succession. The streams of reflected and unobstructed portions are detected at the inspection station to obtain electrical signals which are processed.
Abstract:
A mechanism and method for precisely arranging two or more optical elements, such as those incorporated into photoelastic modulators (PEMs), at a specific angular orientation. The method includes supporting one optical element in an annular mounting member that has an optic axis, and supporting other optical elements in other annular mounting members that have optic axes, and concentrically stacking together the two or more mounting members about a central axis in a manner such that one mounting member may be rotated relative to the others about the central axis and such that the optic axes of the mounting members define an optics angle, and rotating one mounting member relative to the others to define the specific angular orientation of the optical elements.
Abstract:
A method of protecting a sensor for use in an environment, includes providing a protective enclosure formed in a plurality of sections, at least a first section of the plurality of sections being movable relative to a second section of the plurality of sections so that the protective enclosure can be placed around at least a portion of the sensor; placing the first section adjacent the sensor while the first section and the second section are in an open state; and moving the second section to place the first section and the second section in a closed state in which the first section and the second section encompass the at least a portion of the sensor.
Abstract:
Techniques for measuring light absorption of liquid samples are described herein. According to one embodiment, an apparatus includes an upper arm having a first measuring surface and a lower arm having a second measuring surface coupled to the lower arm via a hinge. The upper arm is capable of swinging via the hinge. One of the measuring surfaces is coupled to a light source while the other is coupled to a detector. The apparatus further includes an actuator configured to position the upper arm into a first measuring position. The first measuring surface of the upper arm and the second measuring surface of the lower arm are spaced approximately to contact and sandwich a liquid sample in between to form an optical path, such that light generated from the light source is received and detected through the light path by the detector for measuring light absorption by the liquid sample. Other methods and apparatuses are also described.
