IPC: G06K7/10
Filed: 1992-01-07
Abstract: A laser beam scanner for use in a code reader or the like including more than two optical-path-length changing units inserted in the beam path to change the optical path length of the beam between the beam emitting unit and the scanning unit such that the distance from the scanner to the focal point of the beam can be changed. The optical-path-length changing units are controlled by a control unit which receives an output from a distance measuring unit. The distance measuring unit measures the distance from the laser beam scanner to the object to be scanned and indicates to the control unit to adjust the optical-path-length so that the focal point of the beam is at the same distance as the object to be scanned.

Abstract: A phase difference signal generator (10) responds to two input signals (fv, fr) to generate two phase difference signals (Av, Ar) which rise at a time interval corresponding to the phase difference between the two input signals and fall at the same time. A lagging signal detector (15) detects a lagging one of the two phase difference signals and a pulse generator (17) responds to the detected output from the lagging signal detector (15) to generate an appendage pulse of a width larger than a predetermined width. The appendage pulse (Afr, Afv) is appended, by a pulse appending circuit (16), to each of the two phase difference signals to form an extended phase difference signal (φv, φr). A phase difference detector (14) detects the difference between the two extended phase difference signals and outputs a low-frequency component of the difference as a voltage corresponding to the phase difference between the two input signals.

Abstract: A method and apparatus by which elastic properties of rock formations are determined includes a downhole logging device which has two internal accelerometers mounted within to measure the acceleration of the device. A reference displacement of the device is determined by measuring the acceleration outside the borehole while the device is suspended in air. The output of the accelerometers is measured in the borehole. Integrating the acceleration outputs of these accelerometers twice yields the displacement in the borehole. Changes in the displacement of the device are indicative of various elastic properties of formations surrounding the borehole. Using two accelerometers to determine displacement allows the continuous logging of Young's modulus and other elastic properties of rocks surrounding a well bore. In an alternate embodiment, geophones are used to measure the velocity of the device and their outputs are integrated once to yield displacement.

Abstract: A guide wire (20) for a catheter has a solid tubular portion with a flexible body fixed to its distal end (22). The distal end (22) of the body may be composed of a material more radiopaque than its proximal portion. Optical fibers (24) are disposed within the assembly and terminate in a radiopaque tip at the distal end (22) of the body. The guide wire (20) may have a longitudinal marker wire (32) for providing stiffness and radioscopic tracking characteristics. The guide wire (20) has a proximal end attached to the tube and a distal end (22) that also terminates in the tip. The invention may be maneuvered and positioned in a vascular area like a conventional guide wire. Then, laser energy from a laser light source at a proximal end of the guide wire is conveyed to the vascular area by the optical fibers (24) to ablate an obstruction. A larger catheter may then be slid over the guide wire to continue the ablation operation. Employing polyester tubing for the distal body, the guide wire may be used in peripheral angioplasty applications. Alternatively, the distal body may be implemented with a metal coil and may be used in coronary angioplasty.

Abstract: A self-routing crossbar switch (100) is disclosed. The self-routing crossbar switch (100) interconnects a plurality of processors with a plurality of memory modules. In a self-routing crossbar switch (100) connecting N processors and N memory modules, a processor is connected to each input port (103) and a memory module is connected to each output port(102); each of the N processors can transmit a memory request simultaneously provided that there is no port contention and no bank contention. Port contention occurs if two or more processors attempt to access the same output port of the self-routing crossbar switch (100) at the same time. The memory module consists of several memory banks that are connected in an interleaved manner. If the memory bank is accessed before it is ready to accept a new request, bank contention is said to have occurred. In the proposed invention, the requests directed to a port are first passed through an aligner (116) and a conflict resolution logic (117). There is one aligner (116) associated with each output port. The aligner (116) inputs the requests directed at an output port and aligns them so that at the output of the aligner, all the active requests appear in a consecutive fashion. The conflict resolution logic (117) facilitates to resolve the port and bank contention.

Abstract: An apparatus is presented for economically making crystallized glass products from waste ash produced from the sewage sludge dewatered by organic matters, which is usually regarded to be difficult to process. The melting is performed in two furnaces: the primary melting furnace and the secondary melting furnace. The primary furnace melts waste ash and the primary melt is charged into the secondary melting furnace. The glassy material produced in the secondary melting furnace is charged into a crystallization furnace to convert the glassy material to a crystallized glass product. This basic configuration of the apparatus allows the production of either irregular shaped crystallized products, such as crushed stone like products, or crystallized manufactured products, such as tiles and blocks, depending on the combination of processing equipment and their operating conditions. The apparatus enables the production of crystallized glass products from waste ash feed economically, because of the flexibility and versatility in the design of the apparatus.
