Patent CA-2043176-C (CA)
Title: Z-buffer quantization of three-dimensional lines
Inventor: ALBAUGH VIRGIL A
IPC: G06T15/40
Filed: 1991-05-24
Granted: 1995-09-26
Abstract: A method and apparatus is provided which allows a computer  graphics  system  to  accurately  determine  the actual depth value for pixels on a display screen which lie at the same depth as an associated surface.   The associated surface is identified such that the delta z value with respect to the x and y direction along the surface can be calculated.   The present invention then determines whether the line being considered is contained within  a  surface,  or  is  an  edge  lying between,  and adjacent  to  two  surfaces.   If  the  line  is  contained within a surface, the delta z value is initially added to the known endpoints of the line and then successively added,  in the  incremental x or y directions,  to  the pixels selected to represent the line. If the line is an edge,  and includes  selected pixels which lie on both associated surfaces,  a filter is invoked that prevents those pixels corresponding to the surface, other than the surface  first being considered,  from being processed. The pixels being considered are then drawn in the same manner as a line within a surface.  In this manner, the actual z value for each selected pixel can be determined and any hidden line, hidden surface removal problems are eliminated.

Title: Method of coding 32-kb/s audio signals
Inventor: FESSELER PETER
IPC: H04B1/66
Filed: 1992-08-11
Granted: 1998-02-17
Abstract: For audio signals (50 to 7000 Hz), good speech quality is to be achieved at a data rate of 32 kb/s (also for music signal(s), which requires a considerably greater data reduction than hitherto known.            For a further data reduction of the magnitude values of the coefficients obtained by FFT, the absolute threshold of hearing and a relative threshold of hearing known as masking effect are taken into account in fixing the quantization levels. This is followed by a variable quantization.

Title: Three-dimensional maximum a posteriori (map) tracking
Inventor: LO ALLEN K
IPC: G01S7/02
Filed: 1993-03-22
Granted: 1996-08-13
Abstract: An automatic  detection apparatus (20) and method (20a) applies the Short and Toomey algorithmic  processing procedure to a frequency and beam direction windowed and time segmented  set of FFT magnitude detected data, comprising time, frequency and beam direction data, to determine the presence or absence of narrowband lines indicative of target tracks.  This is achieved by storing the time, frequency and beam direction data, and then processing (32, 33) this data using a predetermined three-dimensional maximum  a posteriori procedure whereby individual target tracks associ-ated with each beam direction are concurrently processed, and whereby transitions are made between adjacent beam directions in order to process target tracks having a maxi-mum signal to noise ratio to provide for detection of a target (11).  An output target track is generated  by combining the high signal to noise ratio portions of the processed individual target tracks into a single output target track.  The present invention extends the tracking capabilities that are obtained using the Short and Toomey processing  pro-cedure from two dimensions  to three dimensions, and this added dimension provides spatial tracking in addition to spectral tracking.  The spatial tracking is performed con-currently with the spectral tracking in an array processor.

Abstract: A method for simultaneously correcting excessive radial force variations and excessive  lateral  force variations in a pneumatic tire (10) is provided.  The method  as  represented by the  selected  Figure  1  is characterized by the steps of indexing a tread (12) on the  tire  (10)  into  a  series  of circumferential increments I(n), and obtaining a series of radial force measurements R(n) corresponding to these increments and a   series   of   lateral   force   measurements   L(n) corresponding to these  increments.   A radial  grind component  RSGR(n),  a  first  lateral  grind  component L1SGR(n), and a second lateral grind component L2SGR(n) are generated for each of the increments I(n) by a computer  (32).   These grind components represent the amount of material removal necessary to correct for either excessive radial force variations or excessive lateral  force  variations  in  the  tire.    The  grind components RSGR(n), L1SGR(n), and L2SGR(n)  are used to generate   first   and   second  radial/lateral   grind components R/L1SGR(n) and R/L2SGR(n) which represent the amount of material removal on first and second shoulder regions (121, 122) of the tread (12), respectively, of each increment I(n) necessary to simultaneously correct excessive radial and lateral force variations.  Material is then  removed  for  the  first  and second  shoulder regions (121, 122) of the tread (12) of each increment I(n) according to the value of the corresponding first radial/lateral grind component R/L1SGR(n) and the value of  the  corresponding  second  radial/lateral  grind component R/L2SGR (n), respectively.

Abstract: Magnetic cartography process and apparatus.      According to the invention, measurements are performed by means of mag-netic field sensors placed in "fish" (10) moved in the area to be mapped, gradients are determined on the basis of the difference between the meas-urements supplied by two sensors at the same time, this applying to any pair of sensors, and/or on the basis of the difference between the meas-urements supplied by the same sensor at two different times, this applying to any sensor, which leads to at least one map of gradients which is broken down into a map of regional field gradients and a map of local field gradients. On the basis of the latter, a determination takes place of the geological field relative to the area, or the gradients of said field and then the local field, by adding the geological field to the regional field determined on the basis of its gradients by an inversion and direct calcu-lation method.

Abstract: In order to change a subscriber alert mode of a radio pager from an audible alert mode to an inaudible alert mode, a normally open function switch is depressed while the radio pager operates in the audible alert mode.      The function switch is subsequently depressed. Following this, a timer is set to count up to a predetermined time period. A pager display exhibits a silent time duration for which the pager will operate in the inaudible alert mode if the timer counts up the predetermined time period. Subsequently, another timer is set to count up to a predetermined time period if the function switch is released. Thereafter, if the second timer counts up the second predetermined time period and if the function switch remains released, the radio pager is set to operate in the inaudible alert mode for the set silent time duration.

Granted: 2004-03-30
Abstract: A portable hardwood floor system of interconnected floor sections supported in spaced relation over a substrate includes a plurality of mounts attached to the bottoms of each of the interconnectable sections. Each mount includes a resilient pad to resiliently support the portable floor system above the base and a glide member located below the pad. The glide members are substantially noncompressible under normal floor loading conditions and have a relatively low coefficient of friction with respect to the base. The glide members are slidable on the base to enhance maneuverability in positioning and aligning the interconnectable floor sections, thereby to facilitate interconnection of the sections to form the floor system.      The glide members also protect the portable floor section and/or the base and are also sufficiently durable to withstand frequent handling commonly required of a portable hardwood floor system.
