Patent CA-2015228-C (CA)
Title: Adapter for microscope
Inventor: RATHBONE RICHARD RODION
IPC: G02B21/16
Filed: 1990-04-24
Granted: 2000-01-25
Abstract: The present invention concerns an adapter to be coupled to an objective lens of a microscope comprising a body member having a first coupling means at one end thereof to receive an objective lens of a microscope and having a second coupling means at the other end thereof to receive a microscope component. The body member has an axial light path running longitudinally therethrough and has a radial light path which intersects the axial light path. A source of light is disposed in the radial light path. A first filter is disposed in the radial light path downstream of the source of light for passing light at wavelengths which excite fluorescence in a specimen to be examined in a microscope and to remove light at wavelengths where visible fluorescence emission occurs in the specimen. A mirror is disposed in the intersection of the axial light path and radial light path. The mirror passes light through the axial light path and reflects light at excitation wavelengths, but does not reflect light at emission wavelengths. A second filter is disposed in the axial light path and is disposed above the mirror and adjacent the second coupling means. The second filter blocks excitation wavelengths which pass through the mirror. The adapter can easily be attached and detached to a conventional microscope. The adapter can provide fluorescence microscopy capability to a conventional microscope which was not designed for fluorescence microscopy.

Title: Technique for determining signal dispersion characteristics in communications systems
Inventor: CHAO TZY-HONG
IPC: H04L27/38
Filed: 1990-10-11
Granted: 1994-10-04
Abstract: Abstract of the Disclosure The present invention covers the notion of determining signal dispersion characteristics, such as amplitude, phase and delay, by transmitting training sequences. More specifically, each sequence comprises a plurality of predetermined symbols and is transmitted two or more times. Detection of each training sequence is provided by a correlator at the receiver. This detection creates a signal peak for each training sequence at the output of the correlator. Between the peaks, a "quiet zone" is created which permits signal dispersion in this zone to be characterized with respect to amplitude, phase and delay. Two different quiet zones are utilized toresolve ambiguities which arise in determining the aforesaid signal dispersion characteristics.

Title: Integrated hardware generator for area fill, conics and vectors in a graphics rendering processor
Inventor: PEASLEE JOHN M
IPC: G06T11/20
Filed: 1991-09-04
Granted: 1996-06-18
Abstract: An integrated hardware generator (12) for generating digital signals representa-tive of vectors, polygons and conics primitives and area fills therefor. The primitive signals are used in the formation of a final digital output signal read into a bit map memory  (22) of a graphics display processor. Its operation is based on applying one or more of a set of internal subfunctions to generate mathematical solutions for render-ing each geometric shape as a graphics primitive digital signal. The basic building block of the generator (12) is a digital differential analyzer (60) which is adapted to ac-cumulate fractional (subpixel) components of x/y coordinate data and to signal when the accumulation overflows across pixel boundaries. This occurrence enables an in-crement or decrement of the x/y coordinates that indicate the pixel address to be loaded (drawn). The digital differential analyzer (60) forms an independent vector generator and comprises a pair of input differential comparators (62) an arithmetic logic unit (64) and register and counter files (66 and 67). On receipt of a command from a host processor (14) the comparators receive updated x and y data, compares them to the present values which are stored in the register file (66) and forwards the differences to the arithmetic logic unit (64). When either the x or y value exceeds the pixel boundary, the arithmetic logic unit (64) computes the coordinates of the next pixel to be filled and inserts them into the register file (66) to replace the previous values.

Granted: 1996-04-30
Abstract: An arrangement to prevent a premature ignition of an active charge, which is to be ignited by means of an adjustable time-delay fuze and belongs to a projectile that is expended from a firing barrel by means of a propellant charge, is provided which is based on a mechanical and a pyrotechnical safety element.   In so doing,  the ignition path between a first delay element ignited while firing and the active charge of the projectile can be blocked by a barrel probe that can be moved at right angles to the firing direction and that in its position blocking the ignition path can be arrested by an acceleration probe that can be moved counter to the firing direction and, as long as the projectile is located in the firing barrel, by the firing barrel wall.  A second delay element, that can also be ignited while firing and exhibits a shorter delay period than the first delay element, pressurized the barrel probe with gas pressure in the direction of  its end safety position following expiration of its delay period.
