Patent CA-2109739-C (CA)
Inventor: DIXON WILLIAM L
IPC: G02C13/00
Filed: 1993-11-23
Granted: 2000-02-01
Abstract: In accordance with the invention a holder is provided for an eyeglass frame having a pair of lens rims spaced apart by a bridge. A pair of supports are fixed in spaced apart relationship on a base plate and a cradle is journalled between the supports to rock beneath an axis spaced from and parallel to the base plate. A pair of jaws transversely mounted on the cradle in relation to the axis is biased toward closing and has a mouth accessible from above the axis. One or both of the jaws inwardly tapered from the mouth to a narrow passage and outwardly tapered from the narrow passage to a throat. The throat has inwardly extending seats. Thus, when a frame is inserted transversely into the mouth toward the throat with its upper rims against one of the jaws and its lower rims against the other of the jaws, the jaws open against bias to pass the frame through the narrow passage and then close under bias to secure the frame in the throat and on the seats. Preferably, the seats are aligned on the jaws so as to support the frame substantially along a plane parallel to the base plate when the cradle is in a normal angular orientation with respect thereto and to support either of the rims substantially along that plane when the cradle is rocked to left or right angular orientations with respect thereto. The cradle is preferably journalled snugly enough to be frictionally secured in its normal, left or right orientations as desired. A tongue extending from the cradle is biased for reciprocal motion between the jaws and to extend from beneath the throat toward the narrow passage to center the frame transversely across the axis while the frame passes through the narrow passage to the throat.

Abstract: An asynchronous transfer mode (ATM) traffic control framework is based on an integrated usage parameter control (UPC) approach, which approach provides a unified and scalable solution to the issue of quality-of-services (QOS) levels over a range of anticipated services in ATM based networks. The approach is consistent with emerging ATM Forum and CCITT standards. Additionally, a UPC-based call and burst admission control providing the desired QOS over periods of network overload by call/burst admission control and traffic shaping of source stream preferably uses a dual leaky bucket.

Abstract: An apparatus for controlling a piezoelectric transformer is disclosed. A transformer driver supplies the transformer with a driving voltage the frequency of which is controlled by a frequency oscillator. A load current monitor observes a load current flowing through a load such as a fluorescent lamp which is powered by said transformer. A frequency sweep controller controls the frequency oscillator when the transformer is initially energized, so as to execute a downward frequency sweep, wherein the frequency of the driving voltage is swept from a predetermined upper frequency to a predetermined lower frequency. The frequency sweep controller further controls the frequency oscillator, after the transformer has been brought into stable operation, so as to execute a further downward frequency sweep if the load current reduces to a second preset level lower than a first preset level exhibited during the stable operation.

Granted: 2002-05-14
Abstract: A system for determining the shape and dimensions of a surface of an object includes a projector for projecting onto the object a spatially coded pattern of radiation, e.g., light. The system also includes a receiving device capable of imaging the reflected pattern, and a discriminator for determining which portion of the reflected pattern corresponds to which portion of the projected pattern. By this means, a received signal representing less than the complete reflection from the projected pattern can be correlated with a discrete portion of the scanned object.  The procedure is repeated to obtain enough reliable data to generate a reasonably reliable surface profile.  The resulting set of received signals and correlations are used to calculate the shape and dimensions of the object.

Filed: 1996-02-05
Granted: 2000-10-31
Abstract: A hot water extraction process for extracting bitumen from tar sands is taught using a conditioning agent containing an alkali metal bicarbonate and an alkali metal carbonate. A source of calcium and/or magnesium ions can also be added. The conditioning agent replaces the caustic soda agent previously used intar sand extraction. The use of the alkali metal bicarbonate and carbonate substantially eliminates the production of sludge in tar sand extraction and maintains or improves bitumen recovery. The process allows for hot conditioning agent solution to be recycled to the process by use of a recycle storage tank.

Title: Terrain elevation database convergence model
Inventor: GJULLIN ROBERT M
IPC: G06F17/30
Filed: 1995-01-17
Granted: 2006-03-07
Abstract: A convergence model is shown and described for accommodating variation in data post spacing in a digital terrain elevation database (DTED) based on longitude and latitude address values for data posts. Under such a database structure, data posts lying along lines of latitude vary in spacing according to latitude, and converge at the poles with zero spacing therebetween. To scan a circular region of data posts relative to a given data post, e.g., a threat installation this variation in data post spacing is considered by appropriately scaling sample step spacing along radials traversed in executing a radial spoke scan pattern. In this manner, a circular region of data posts surrounding a given data post may be sampled using simple, dedicated hardware despite this variation in data post spacing.

Abstract: A reinforced structural member (10) comprising a solid structural member (12) of recycled plastic having a reinforcing bar (16) inserted therein, extending inwardly from one surface (12a).  A notch (14) is formed in the solid structural member (12) extending inwardly with respect to the surface (12a) against which force is to be exerted.  An untensioned reinforcing bar (16) formed of a material having characteristics of resilience and compressibility different from that of the structural member (12) is inserted and locked into the notch (14). The reinforcing bar (16) is complementary in shape to the notch (14), and is held in place by the density of the solid structural member (12) and fasteners such as screws.  In this way, two dissimilar materials, neither of which alone has sufficient strength, rigidity, or "memory" can be combined to create a durable, inexpensive set of components which substantially exceed the mechanical qualities of either material by itself.
