Title: System and method of rendering curves
Inventor: BALLARD DEAN D
IPC: G09G5/20
Filed: 1994-05-03
Abstract: A system and method of rendering a curve using data look-up tables for rasterizing the curve. The curve is subdivided so that it is approximated by a series of straight line segments of approximately equal length, with no line segment exceeds two pixels in length. The system subdivides any line segment that crosses horizontal axis of two adjacent horizontal scan rows. If the line segment does not cross the horizontal axis of a scan row, the pixel does not require detailed analysis. If the line segment does cross the horizontal axis of a particular horizontal scan row, the system uses look-up tables to determine the distance from the center point of the pixel in winch the line segment crosses the horizontal axis to the point at which the line segment crosses the horizontal axis. The system uses three indices as pointers to the data look-up table containing the desired data. The three indices are themselves pointers to separate index tables in which the multiplication calculations required for the data look-up table have been precalculated and are incorporated into the values stored in the index tables. The index tables also incorporate a reduction in resolution from 1/64 to 1/8 pixel resolution. The index tables are also nonlinear to allow more data entries in areas where the round off error resulting from the resolution reduction are greatest. If the line segment crosses the horizontal axis to the left of the center of a pixel, the logic state for the pixel is changed. The system can be implemented on any computer and operates with any raster scan graphics display unit.

IPC: A47G19/22
Filed: 1993-06-07
Abstract: An integral beverage can closure embodiment (50) having a sealed position for sealing the contents of an opened beverage can (30) and a dispensing position for dispensing the contents is disclosed. A resilient cap (52) with a skirt (54) closely fits over the can rim. The cap defines a tongue (56) that folds over a hinge (82) and is inserted in a slot (60) of the skirt.

IPC: H02G3/20
Filed: 1994-12-13
Abstract: An electrical  junction  box to be  used when supporting  a relatively heavy hanging load from the underside of a joist/beam at an installation site.  In one embodiment a slotted pancake dish internally supports an arcuately displaceable bracket both of which have coincident slots through which to receive fasteners by which the load is to be supported.   A removably disposed lead box in which electrical leads are received extends normally upright to the plane of the pancake dish and is adapted to be positioned thereon off center in communication with an opening through the dish.  A partially circular shell section can optionally be utilized by being removably secured on the pancake dish opposite the lead box so as to cooperate with the lead box when utilized in forming an externally appearing cylindrical cannister-like configuration.  A second bracket vertically depending within the sleeve of the shell section is securable at its top portion to a joist/beam and at its lower portion receives the pancake dish and load via bolts secured thereto.  The second bracket provides for angular adjustment so as to compensatingly accommodate various beam pitches.  Indicia along the exterior of the shell provides guidance in cuttingly removing portions of the shell in correlation to the pitch of the beam in order to receive the beam intervening between the shell and lead box while affording axially vertical orientation of the cylinder.          In another embodiment, a pancake dish and electrical lead box are integrally joined as a unit for direct joist mounting or can be utilized with the second bracket as before.  An optional horizontal support plate is disclosed for use in combination with the second bracket for supporting the load.

Patent CA-2139904-A1 (CA)
Inventor: YAMASHITA KAZUO
IPC: H03B1/04
Filed: 1995-01-10
Abstract: The time constant determined by a high-speed time constant circuit (32) is suitable for high-speed pulling of an output frequency (f0), and the time constant determined by the low-speed time constant circuit (33, 34) is suitable for stabilization of the output frequency (f0) at a corresponding value and suppression of a spurious output frequency.       When the output frequency (f0) is switched from (f a) to (f b), for example, the output frequency (f0) is switched by setting the frequency division ratio (n) in the state in which the switch (S a) is ON, while the switch (S b) is OFF.      Simultaneously, the switch (S a) is turned off, and after the output frequency (f0) is stabilized, the switch (S b) is turned on. The speed of switching the output frequency (f0) is heightened and a spurious output frequency after switching the frequency is suppressed without using an A/D converter or a D/A/ converter having high accuracy.
