Patent CA-2118151-A1 (CA)
Inventor: MAHONEY JAMES V
IPC: G06V30/10
Filed: 1994-10-14
Abstract: To group items in an array, gap data are obtained indicating gaps between items. The gap data are used to obtain threshold data, which are then used to obtain grouping data. The gaps could, for example, be distances between items in a two-dimensional array or differences between values at which items occur in a one-dimensional array. The threshold data indicate a threshold. The threshold would produce a number of groups of the items that is stable across a range of thresholds, and the range of thresholds meets a criterion for largeness of a range. The criterion can require, for example, that the range be larger than the stable range of thresholds of any other number in a set of numbers of groups. The threshold can be obtained iteratively by applying a candidate threshold for each iteration. The candidate thresholds can be incremented, and the iterations can be counted to find a number of groups meeting the criterion. Or the candidate thresholds can be increased by differences between gaps, and a running sum of threshold ranges can be used to find a number of groups meeting the criterion. The threshold can also be obtained directly by finding the largest difference between gap extents and obtaining a threshold within the largest difference. Many types of grouping can be performed, including spatial clustering, segmentation of partially bounded regions, segmentation by local width, and global and local similarity grouping.

Title: Rotary piston pump
Inventor: RAPPENHOENER HANS RICHARD
IPC: F01C1/352
Filed: 1992-12-05
Abstract: Summary The present invention concerns a rotary piston pump for pumping and/or metering media which are capable of flowing or chamber (4) having a cylindrical inner circumferential surface (6) in which at least one inlet (8) and at least one outlet (10) open and a rotary piston which rotates within the cylinder chamber (4), of which at least one region of its outer circumferential area (22) cooperates with and is sealed against the inner circumferential surface (6) of the cylinder chamber (4) and is regionally separated from the inner circumferential surface (6) by a radial stroke distance.  On rotation (arrow 70) of the rotary piston (20), in each case a working chamber (24) which increases in size is formed in the region of the inlet (8) in order to draw in the medium and then on further rotation in the area of the outlet (10) becomes smaller in order to discharge the medium again.  In each case, the working chamber (24) is blocked off during its enlargement or reduction in volume by at least one separating slide (26) upstream of the inlet (8) or downstream of the outlet (10), viewed in the direction of rotation of rotary piston (20), the separating slides being displaced back and forth (arrow 32) in an essentially radial direction to the axis of rotation (34) inside pump housing (2) in such a way that it cooperates with and is sealed against the outer circumferential surface (22) of rotary piston (20).  The displacement of the separating slide (26) is performed automatically by means of a drive device (30) synchronized with rotary piston (20).

Title: Water turbine
Inventor: LAEMTHONGSAWAD PRASERT
IPC: F03B7/00
Filed: 1994-10-20
Abstract: WATER TURBINE        ABSTRACT   The contents of this invention are composed of a turbine which has turbine impellers fixed around the outside of a steel frame. The apertures between each impeller were invented to have a basketlike shape by using iron sheet welded to cover both sides of each aperture. The aperture between the impellers will transform the baskets's shape between each impeller. The use of the baskets are for water storage inside the baskets. The method of how to spin the turbine will start from pumping the water with the water pump from the invented storage well. The water will be pumped up and flow along the pipe then flow into the baskets. When the baskets are filled with water, the water will be stored. The weight of the water will imbalance the turbine and then it will spin. After that the water in the baskets will run off. When the baskets rotate to the end of the lower curved wall water stoppers which are located at the mouths of the baskets, the mouths of the baskets will over turn and water will run off until the baskets are empty. The empty baskets will rotate up to receive the water again. This circulation is continued unceasingly.

Title: Oscillation Polarization Mode Selective Semiconductor Laser, Light Source Apparatus and Optical Communication System Using the Laser
Inventor: ONO TAKEO
IPC: H01S5/12
Filed: 1994-12-05
Abstract: A distributed feedback semiconductor laser selectively performs one of two oscillations in different polarization modes having different polarization planes.  The laser includes a subtrate, a light waveguide formed on the substrate, which at least partially includes an active layer, a a diffraction grating formed around the waveguide, and an injecting unit for injecting a modulation current into a portion of the waveguide.  The waveguide and the grating are constructed such that oscillation wavelengths of the polarization modes are different from each other and minimum values of threshold gain in the polarization modes near the Bragg wavelength are approximately equal to each other. The semiconductor laser can be driven by a minute modulation current and prevents degradation of response characteristics due to dynamic wavelength fluctuation in a high-frequency range when used in optical communication systems in which the switching of polarization mode is performed.
