Patent CA-1310400-C (CA)
Inventor: ISNARDI MICHAEL A
IPC: H04N7/26
Filed: 1989-02-23
Granted: 1992-11-17
Abstract: RCA 85,007 Abstract of the Disclosure A system for transmitting and receiving signals representing a high-definition television (HDTV) image is disclosed.  The signals are sent over two conventional 6 MHz NTSC channels.  A first signal, the main signal, is developed by encoding circuitry from HDTV source signals to be compatible with existing NTSC receivers in that it produces a display on those receivers which is not significantly distorted.  The main signal includes psycho-physically hidden video information which may be used by an extended definition receiver to produce a widescreen image having a higher level of detail than a conventional video image.  A second signal, the auxiliary signal, is developed at the transmitter by decoding the main signal and subtracting the decoded main signal from the original HDTV source signals.  The auxiliary signal, which includes frequency components from 0 Hz to 20 MHz is split into three bands, A (0 Hz-6 MHz), B (6 MHz-12 MHz) and C (12 MHz-18 MHz).  Bands B and C are frequency converted to occupy the 0 Hz-6 MHz band and are time division multiplexed on a line by line basis.  The combined B and C bands are then time division multiplexed with the A band on a frame by frame basis for still images.  For moving images, only the A band is sent.  The receiver decodes the main signal, and, using a motion signal sent with the main signal, decodes the auxiliary signal.  The decoded main and auxiliary signals are combined to reproduce the HDTV image.

Abstract: Abstract of the Disclosure DUAL DENSITY DIGITAL IMAGE SYSTEM      A data processing system is disclosed for storing and displaying digital images, including a workstation having a document input scanner for digitizing document images at a first resolution, an image display unit for displaying digitized document images at a second resolution which is less than the first resolution and a printer for printing digitized document images at a third resolution greater than the second resolution.  The system reduces communications traffic and assures fast access time on the network since the bulk of the traffic will utilize the smaller compressed data records required for the second resolution.  However, these improvements in communication traffic and access time do not sacrifice the availability of high resolution compressed data records occasionally needed for printing and other high resolution operations.

Abstract: The present invention is directed to halogenated aromatic epoxy resins wherein the halogen atoms are in the meta position with respect to a glycidyl ether group attached to an aromatic ring and to advanced epoxy resins prepared from the halogenated aromatic epoxy resins.  The advanced epoxy resins result from the reaction of a relatively low molecular weight epoxy resin and a polyhydric phenol wherein at least one of the reactants contains at least one halogen atom which is meta with respect to a glycidyl ether group or a hydroxyl group attached to an aromatic ring.  These advanced epoxy resins are particularly useful in circuit boards or other electrical laminate applications, potting and encapsulation applications and other applications where flame retardant properties are desired.  When cured with a suitable curing agent, the advanced epoxy resins of the present invention possess an improvement as compared to an advanced epoxy resin containing halogen atoms which are ortho with respect to a glycidyl ether group in at least one of thermal stability, glass transition temperature, relationship of viscosity to molecular weight and resistance to forming hydrolyzed halides in the presence of a refluxing solution of an alkali metal hydroxide.

Abstract: A safety arrangement used while fitting lift doors has the form of a fittable railing which is screwed on at the bottom via two articulated parallelograms (2) in the sill recess of the shaft door opening. By means of the articulated parallelograms (2), the guard railing (1) can be brought into two different horizontal positions (A and B) and thus displaced by the amount X without removing it from the shaft door opening. This makes it possible to fit the guard railing (1) while the barricading of the shaft door opening provided by the owner is still in place and is not to be removed until the shaft door opening is closed off by the in the meantime fitted and closing shaft door. Therefore, this safety arrangement ensures a permanent guard against persons falling into the shaft during fitting of the shaft door. The guard railing (1) has a device for adaptation to different widths of opening and a constant distance of the articulated parallelograms from each other.

Abstract: In a process in which a first process variable is manipulated so as to maintain a second process variable substantially equal to a desired value for the second process variable, a set point for the first process variable is generated based on the difference between the actual value of the second process variable and the set point for the second process variable. The magnitude of the set point is determined by the probability that the second process variable may reach an undesirable value and thus control using the set point takes into the consideration the fact that large control actions may be required under some circumstances and minimal control actions may be required under other circumstances in a process.

Abstract: A method and apparatus for measuring the strength of a radio frequency (RF) signal subject to Rayleigh fading. The strength of the RF signal is sampled two or more times during a predetermined time interval and the sampled signal strength having the largest magnitude is selected. The selected signal strength is a reasonably accurate measure of the signal strength since the true average strength of a Rayleigh fading signal is close to its peak signal strength. The inventive method and apparatus is particularly well adapted for use in a scanning receiver located in a base station radio (111, 121, 131) of a cellular radiotelephone communications system. The scanning receiver includes an antenna selector (102) for selecting one of a plurality of sector antennas, an RF signal receiver (104) tunable to a plurality of different RF signal frequencies, an analog-to-digital converter (106) for converting RF signal strength samples to a binary data signal and a microprocessor (114) together with peripheral devices (108, 110, 112, 116, 118, 120) for controlling the operation of the antenna selector (102), RF signal receiver (104) and analog-to-digital converter (106).
