Abstract:
A method for lateral chain modification of aryl main chain polymers with aromatic ketones or aldehydes containing tertiary basic N-groups is described. The modification can be accomplished via addition of an aromatic carboxylic acid or an acid derivative containing a tertiary amine moiety to a metallized polymer. The tertiary amines on the modified polymer can be converted to quaternary amines with halogen alkanes. Modification of the aryl main chain polymers with aromatic groups containing sulphonic acid radicals is also described. The polymers formed can be crosslinked and prepared for use in a wide variety of membrane technologies including ion exchange, dialysis, reverse osmosis, nanofiltration.
Abstract:
A method and apparatus for calibrating the output signal of a linear position detector without accessing the interior of the detector housing is provided. According to one exemplary embodiment, a magnet is selectively movable toward and away from the exterior of the electronics housing, and a sensor is provided within the housing for sensing the presence of the magnet. According to this embodiment, the linear position detector is calibrated by setting a movable marker at the desired position and pushing the magnet toward the housing. The sensor then detects the presence of the magnet, and a processor saves the position of the marker as a reference point. All future positions of the marker can then be scaled based upon the reference point. Thus, the linear position detector can be calibrated without the need for opening the electronics housing and potentially exposing the electronics components to moisture, contaminants, and/or static electricity. Preferably, the magnet is connected to a push button on a base, and the base includes an attachment mechanism, such as a clip for example, to attach the base to the position detector.
Abstract:
A scanning apparatus for use in a scanning optical system comprises a laser transmitter to produce a transmitter beam. This transmitter beam is deviated by a beam scanner, e.g. a tiltable mirror, to produce a pattern of a scanning beam. There are bearings which define first and second axes of rotation perpendicular to each other and intersecting each other in an intersecting point for allowing the beam scanner to scan. In front of the beam scanner is a window of transparent material in the shape of a spherical cap so as to define a central axis and a central point. The central axis intersects the intersecting point of the two other axes, and this common intersecting point coincides preferably with the central point of the sphere of the window.
Abstract:
A system for recording an object space has a opto-electronic distance sensor which uses a signal propagation time method, and a transmitter for transmitting optical, signals, as well as a receiver (E) for receiving optical signals, reflected by objects located in the target space. The system comprises a scanner for deflecting optical axes of the transmitter and receiver (S and E). The optical axes of the transmitter and receiver (S and E) for example, are substantially parallel. An evaluation system determines distance values from the propagation time or phase position of the transmittal optical signals, and the space coordinates of the individual data elements result from the distance values and the beam deflection implemented by the scanner. The system comprises a rotary measurement head mounted on a pillow block, and a mirror system fixed relative to the measurement head, which deflects beams axially incident on the hollow shaft in the radial direction and vice versa. The radiation from stationary transmitter (S) can be introduced in the axial direction relative to the hollow shaft and can be transmitted in the radial direction through the mirror system. The radiation reflected by the targets located in the object space, can be deflected by the mirror system in the direction of the axis of the hollow shaft and be supplied to the receiver (E), which is also stationary.
Abstract:
A laser-based target detection system applicable to search and rescue operations takes into account a plurality of optical attributes in the energy delivered to, and received from, a target-containing area. In addition to analyzing the returned optical signature for sufficient energy reflected by a potential target at a primary laser wavelength, the system also senses the target's effect on a supplemental optical attribute. Only when sufficient amplitude at the primary wavelength is detected in conjunction with a substantial effect on the supplemental optical attribute is a valid target confirmed. The supplemental optical attribute can be amplitude at a wavelength other than the primary wavelength, with the system looking for a high degree of attenuation at the non-primary wavelength, or polarization. with the system preferably looking for change of orientation in the return optical signature. The system includes scan head chassis (102) for transmitting energy to a target-containing area, electronic chassis (104) for processing the received optical energy, laser pulse drive (106), and laser cooler (108).
