Patent CA-2020239-C (CA)
Title: Interconnect fabric providing connectivity between an input and arbitrary output (s) of a group of outputs
Inventor: ENG KAI Y
IPC: H04L12/56
Filed: 1990-06-29
Granted: 1996-12-17
Abstract: This invention is an inventive N input by L output interconnect fabric. In operation, packets comprising an information field and an address are received at the N inputs to the interconnect fabric, and the address in each packet is mapped to a group of outputs, rather than to any particular output. Each packet is then routed to any available one of the interconnect fabric outputs associated with the group to which the packet is mapped. If a number of packets destined for the same group simultaneously arrive at the interconnect fabric inputs and the group to which they are all destined does not comprise enough outputs to accept them, then all packets in excess of the number that the destined group can accept are simply discarded. The probability of lost packets due to such discarded packets is acceptably small. In one exemplary embodiment, the invention can be utilized to build arbitrarily large packet switches.
Patent CA-2024488-C (CA)
Title: Method and apparatus for line power monitoring for uninterruptible power supplies
Inventor: BAXTER RICHARD V JR
IPC: H02H3/50
Filed: 1990-08-31
Granted: 1995-05-02
Abstract: AC line monitoring is provided for uninterruptible power supplies to detect AC power system line faults by comparing the presently received cycle of the AC power line signal with a reference waveform.  The reference waveform is formed of a composite of waveforms from prior cycles which adapts over time to the shape of the AC power line waveform, so that waveforms other than pure sinusoids can be accepted without triggering false fault conditions.  The composite reference waveform may be formed of essentially all samples from prior cycles with exponentially decaying weighting.  An excessive deviation of the current waveform from the reference waveform results in a fault being detected which causes switching of the uninterrupible power supply to provide backup power.  The RMS value of the power line voltage is also estimated on a substantially real time basis, preferably by calculating the RMS value of the reference waveform, to provide a fault condition signal when the estimated RMS value falls below a selected level, which also can be utilized to cause switching of the uninterruptible power supply.

Title: Facsimile device having self-diagnostic function and maintenance and control method thereof
Inventor: FUJII YOSHIHARU
IPC: G03G15/00
Filed: 1990-11-15
Granted: 1995-02-21
Abstract: A facsimile device and a maintenance and control method thereof are disclosed, which enable a reduction in time  load  and  economic  load  incurred  by users  and  a maintenance and control station with respect to maintenance and control of the facsimile device.  The facsimile device includes   a trouble   type   determining   circuit   for determining, when trouble occurs, whether or not the type of trouble can be handled by the users.  A control circuit controls a sending/receiving circuit so that,  when the trouble  type  determining  circuit  determines  that  the trouble  cannot  be  handled  by  the  users,  the  trouble information is sent to a facsimile unit of the maintenance and control station.  Therefore, even when trouble occurs that cannot be handled by the user, the trouble can easily be quickly dealt with, resulting in a reduction in time load and economic load on the user and the maintenance and control station with respect to the maintenance and control of the facsimile device.

Title: Tree seedling planting implement
Inventor: NEAL ARCHIE E
IPC: A01G23/02
Filed: 1991-06-27
Granted: 2001-06-12
Abstract: Disclosed is a seedling planter, particularly useful far tree seedlings, which has a main frame adapted to be hitched behind a pulling vehicle. The main frame is supported above the ground by the hitch and support wheels located near the rear of the planter. The support wheels are preferably mounted on a carriage which is pivotable relative to the frame thereby allowing the force exerted by a set of intermediate packing wheels to be varied. The seedling plantar uses a novel planting assembly which incorporates two primary structural members; a first planting assembly piece or link which is connected to the frame, and a planting arm which is pivotally connected to the first piece. The first piece is movable to vary the height of the pivot axis about which the planting arm rotates. The planting assembly also preferably includes a soil height level detection subsystem. The detected soil height level is used by a height control subsystem to automatically control the downward extension of the first planting assembly piece. The planting arm is thus positioned at a desired predetermined height above the soil as it is rotated into the ground to provide consistent planting depth. The planting arm mounts a seedling holder which clamps the seedlings along the rear edge of the planting arm. The seedling holder has jaws which are opened by interaction with a cam. Extension of the planting arm downwardly causes the seedling to be automatically grasped by the jaws. A  lever arm actuator automatically opens the seedling holder when the planting arm is extended to thereby release the seedling into a short furrow formed in the soil by the extended planting arm. Also described are novel methods.

Title: Sub-micron device fabrication
Inventor: WHITE DONALD LAWRENCE
IPC: G03F1/28
Filed: 1992-02-21
Granted: 1999-02-02
Abstract: Fabrication of integrated circuits - electronic, photonic or hybrid - permits attainment of higher device density. Pattern delineation with smaller design rules than previously associated with delineating radiation of given wavelength is the consequence of use of phase masks. Compared with earlier used, binary valued phase masks, the multiple values of those on which this fabrication depends permits improved effectiveness in lessening of edge-smearing radiation of consequence (of diffraction-scattered delineating radiation at feature edges). Phase masking mayprovide, as well, for feature generation by interference, and for reduced intensity of unwanted image hot spots by diffraction.

Abstract: A unique fluid connector is disclosed that quickly connects a tube within a housing bore, while providing a strong, fluid tight seal.  The tube has axially spaced radially greater diameter upset portions with a sleeve and a locking member trapped between the upset portions.  The locking member includes resilient arms which secure it within the housing bore.  The sleeve has a notch at an inner axial end which abuts the inner upset portion to retain the tube within the bore. An O-ring is positioned axially inwardly of the upset portion.  The sleeve and the inner upset portion both abut the O-ring to provide a fluid tight seal between the tube and the housing.  In a unique method, a tube unit is assembled by forming the outer upset portion on the tube.  The locking member and sleeve are then moved onto the tube.  The inner upset portion is then formed on the tube to secure the locking member and the sleeve on the tube.  An O-ring retaining portion is then formed on the tube, and the O-ring is positioned onto the tube.  The assembled tube unit is then inserted into the housing bore.  Further, a flexible tube may be connected to an outer end of said tube by crimping a metal ferrule radially inwardly.
