A signal processing means (40) outputs a signal (41) representing a number when a combination of at least two imagers (11), (12) detects a spatial arrangement of a plurality of code portions of a coded data source (60)—where the spatial arrangement of the plurality of code portions represents the number, and where imager combinations can comprise spatial, temporal, and light property combinations.

An imager (11) has a locate mode (13) which detects light (31A, 31B) having a preset light property from at least one locator (21) in the imager field of view (12); and has a react mode which is caused by the locate mode to select light from a code region (22, 32A, 32B, 33B) over light not from the code region (81) and which outputs a signal (41) representing code in the code region.

An improved high resolution method and apparatus are described for sensing and determining the spatial coordinates of a movable object with respect to a energized conductive surface. The coordinates of the object are precisely measured with respect to a two-dimensional coordinate system independent of the third orthogonal dimension, thereby avoiding significant measurement errors due to variations of the object position in the third orthogonal dimension. The system also ascertains the coordinate position of the object in this third dimension, which can then be utilized as an independent control variable in the system. Further, the system can accommodate a number of energized conductive surfaces over which the object may be positioned and can determine the spatial coordinates of the object with respect to any such surface. In general, the system of the present invention can ascertain the generalized n-tuple position vector of the object with respect to each of a plurality of generalized, energized conductive surfaces. In any of the foregoing forms, the energized conductive surfaces can be transparent. The system described improves the precision and accuracy of the location of the selected point and hence the precision and accuracy of the spatial coordinates calculated by the system for display. The improvement in system performance is the result of innovations in fundamental design concepts utilized throughout the system.

A product tailors energy deposition. In one form, the product includes a magnetic field. The magnetic field is in a pre-set tailoring relationship with a body, a target volume in the body, and a electron-photon cascade in the body produced by a photon beam, where the photon beam and the electron-photon cascade are substantially parallel to a beam path. In one form, the magnetic field has a component non-parallel to the beam path in the target volume, which is at least one hundred gauss. The target volume having a target density and the body having a body density proximal the target volume. In one form, the tailoring relationship causes a desired distribution of energy deposited in the body and the target volume.

An improved apparatus for rapidly compressing, expanding, and displaying broad band information which is transmitted over a narrow band communications channel. In the preferred embodiment, a video image is cyclically assembled in low resolution and high resolution phases from digitized data representing gray level intensity for individual pixels which have been grouped into pixel. During the initial cycle of the low resolution phase, a representative sample of cell intensity values is transmitted by a sending station to a receiving station according to a video compression routine. The receiving station then uses a video expansion routine to calculate an intensity value for those pixels whose intensity values were not transmitted and displays an initial image. This image is refined during subsequent low-resolution cycles by additional transmissions from the sending station which replace the calculated cell intensity values with an actual or better approximation value for that pixel. During the high resolution phase, an error determination routine or external input from a viewer selects those pixels containing the greatest deviation in intensity levels from the input video image. The error compression and expansion routines substitute a plurality of individual pixel intensity values for previously calculated intensity values. The present invention also discloses an apparatus for allowing color capable stations to send or receive color transmissions while retaining the capability to interact with noncolor stations. Color data is compressed and interleaved with black and white data by a color capable sending station and subsequently separated and expanded by a color capable receiving station.
摘要:
A metallurgical process involves providing an ingredient enclosure and placing a plurality of granules of a first material in the ingredient enclosure. The enclosure is formed using a blank (40) where a deformation former (28) deforms the blank against an aperture (24) in a plate (FIG. 1). No die blank is required on the opposite side of the blank from the deformation former. The first material is added into the formed container component. In one form, two approximately symmetrical hemispherical container components are attached together to form the enclosure. A metallurgical process furnace having a chamber in which ingredients for the metallurgical process are added is provided and the ingredient enclosure and the first material are added to the chamber. The chamber is heated after the addition of the ingredient enclosure and the first material to the chamber, although it may also be heated prior to such addition.
