Title: Apparatus and method for determining particle size distributions
Inventor: STRICKLAND MICHAEL L
IPC: G01N15/02
Filed: 1995-04-14
Abstract: An apparatus and method are disclosed for obtaining and analyzing light scattering data to determine the size distribution of a group of dispersedparticles that scattered the light. The apparatus and method use a two-dimensional array of photosensitive pixels such as a charge-coupled device (CCD) or an array of solid-state photodiodes. The analyzer illuminates the particles with a dose of light in a collimated beam from a light source so as to scatter light of the beam, and at least a portion of the light interacting with the particles is detected with the photosensitive pixel array. The pixels are functionally equivalent and the analyzer dynamically configures and re-configures at least a portion of the pixels into a variable number of data collection areas which correspond to a selected set of scattering angles. The analyzer also determines whether and, from the pixel output data, where an unscattered center of the incident light beam intersects the pixel array. Thus, no precision mechanical alignment of the light source and the pixel array detector is required prior to operation of the analyzer. Furthermore, the ability of the analyzer to determine the unscattered beam center allows the analyzer to classify each of at least a portion of the pixels to data collection areas according to a function of the geometric relationship the pixel bears to the location of the beam center.

Inventor: KINASCHUK JOANNE
IPC: A47K10/38
Filed: 1996-10-22
Abstract: This invention is for TODDLERS, it a specially designed toilet paper holder, which attaches to a wall or flat service via strong rubber suction cups, from the suction cups is a hard plastic tubing which extends outwards from the wall. The idea is to have 2 suction cups which would be approx. 2-3 inches in diameter, directly attached from each suction cup would be the plastic tubing which extends approx. 6-7 inches, is about 2 inches in diameter and which joins at the other end with a plastic tube that comes down vertically to hold the 2 horizontal tubes in place. On the lower tube there is a spot at either end that allows you to take out the toilet paper roll freely  for the purpose of refill. The reason for 2 suction cups and 2 rollers is to evenly support the structure so that it is a sturdy apparatus.  The whole apparatus, as just described is then covered with a hard plastic cover, which basically covers everything, but you will see a small amount of toilet paper coming from the bottom for useage.  This apparatus's sole purpose is for placement beside the Toddlers "Potty" while potty training, once training is complete then this item could be put away for the next Toddler that comes along! This invention is different from other ones in that my invention is portable will be easy to set up anywhere, for any length of time, and as such can be put away until it is needed the next time, and this is the first apparatus that pertains only to the Toddlers special needs, presently only the adults are beinq taken care of.

Patent CA-2189620-A1 (CA)
Inventor: RICE DANIEL S
IPC: G06T3/40
Filed: 1996-11-05
Abstract: A method and system for resizing images in a computer system. A plurality of buffers are dynamically created in the memory of the computer system. Among the created buffers are a horizontal sampling buffer and two vertical sampling buffers. The horizontal sampling buffer is filled with data from a plurality of rows of the source image. The horizontal sampling buffer is composed of sub-buffers, each constituting a subset of the horizontal sampling buffer. Each sub-buffer is bytewise transposed to provide easy access to different channels of the image data. A filter is then applied to the transposed data with a result being stored in another buffer. The filtered data is then retransposed to assume its original configuration. The retransposed data is stored in a vertical sampling buffer previously created. The foregoing steps are repeated to fill a second vertical sampling buffer. Thereafter throughout the processing, two vertical sampling buffers remain continuously filled to allow vertical filtering without concern for invalid data. When data is no longer needed in one of the vertical sampling buffers for the ongoing filtering, it can be refilled with new data corresponding to the next group of vertical neighbors. By buffering the data, various symmetries can be exploited and known problems such as edge conditions and alignment issues can be handled early in the resizing scheme providing for more efficient processor operation.

Title: Electrical insulated boot
Inventor: SMITH JAMES EDWARD
IPC: H01R4/70
Filed: 1996-12-13
Abstract: An improved design for an electrical insulated "through" boot for a bare joint area formed by two electrical conductors comprising a molded member arranged longitudinally around the joint area and having a main body portion with opposed flap members. Each flap member is coextensive with the main body portion and has a distal end. When the molded member is arranged around the joint area, the distal end of each flap member is wrapped around each other in an overlapping manner to form a seal and to enclose the joint area. The ends of the boot can be secured in place by clamps or wire ties. The boot is easily removed without being destroyed for maintenance of the conductors and is therefore reusable. A further embodiment is for a tee boot which has a perpendicular leg which slips over the riser and which has the opposed flap members which are overlapped over the joint area of the bus bars, and a still further embodiment is for a spout boot which involves two pieces wherein one piece is inserted into the other for the overlapping feature around the joint area. Further embodiments provide an end boot and an end cap boot which also increase the creepage distance for the current leakage to prevent breakdown of the voltage source.

The leg portion of the housing consists of four equi-spaced identical semi-conical wall segments and four concave wall segments joining adjacent semi-conical wall segments to provide a generally truncated conical configuration with a rounded cross or four leaf clover horizontal cross section. The top and bottom end of the leg portion is open.          The foot portion is an inverted dish shape. The dish shaped foot portion has an annular side wall and a top wall. The bottom end of the leg portion is coaxially connected to the top wall of the dish shaped foot portion. An opening is provided in the top wall of the dish shaped foot portion the same size and shape as the internal cross-section of the bottom end of the leg portion. The concrete form of the present invention because of its unique construction provides numerous advantages over conventional fiber tubes. It is easier to dig a hole into which the form can be inserted; the present invention will take about one third the volume of concrete that a similar sized fiber tube and due to its tapered construction, the concrete forms of the present invention will resist upward frost movement.
