摘要： Deinterlacing systems and methods useful with television and other interlaced data signals derive values for pixels on missing lines using best matching values for blocks of pixels through time-recursive comparison of current pixels block values with such values for prior frames of data and also with later frames. Noise propagation is attenuated by mixing of current interpolated pixel data and memory size efficiency is achieved by comparisons based on blocks of pixels, with the block size adjustable for data accuracy. Use of chrominance signal comparisons and reduced data rate coding techniques provide added capabilities to the deinterlacing systems and methods.

摘要： An apparatus (20) is provided for transferring articles (40--40) from a pickup position to a pickoff position and then to a dropoff position. The apparatus includes a pair of pickup arms (60--60) which are spaced apart to engage lugs (42--42) oppositely extending from an article to be transferred. As the transfer arms are caused to be moved rotatably, the article is transferred to the pickoff position whereat the lugs are adjacent to stepped end portions (88--88) of a pair of pickoff arms (80--80). Further movement of the transfer arms causes the article to engage surfaces (92--92) of the stepped free ends of the pickoff arms and to be supported by engagement of the lugs with surfaces (94--94) of the stepped end portions of the pickoff arms. Afterwards, the pickoff arms are turned to allow the article to descend until, at a predetermined position, the lugs of the article become engaged with a conveyor (100) and become disengaged from the pickoff arms. Successive ones of the articles are supported by engagement of the lugs with the conveyor such that main body portions of the articles are submerged in a treating bath beneath the conveyor.

摘要： A laser marking apparatus provides markings of enhanced readability in an outer jacket of repetitively spaced sections along the length of a moving cable which is delivered from a supply source. The cable is advanced under tension and is wound onto a take-up spool. The outer jacket is of a specified color and has an outer surface. The laser marking apparatus includes a first guide roller, a laser marker, an applicator, a coarse brush roller with a first driving mechanism, a fine brush roller with a second driving mechanism and a second guide roller. The first and second guide rollers are disposed adjacent to the supply source before the laser marker and before the take-up spool after the fine brush roller, respectively, in order to guide the cable along a path of travel so that the outer jacket passes adjacent to the laser marker. The laser marker inscribes in the outer jacket markings opening to the outer surface thereof. The applicator applies a wax, the color of which is different from and contrasts with the specified color of the outer jacket, on the outer surface of the outer jacket and in the markings. Afterwards the coarse brush roller removes most of the wax which is on the outer surface of the outer jacket leaving the wax which is in the markings and the fine brush roller removes the remainder of the wax which is on the outer surface of the outer jacket and polishes the outer surface.

摘要： In a facility for conveying PWBs in a path of travel, two stop/clamp devices are magnetically clamped along the path to be spaced in its length and to be within the path width occupied by the traveling board. Each of the devices has stop and clamp elements shiftable as a unit between out positions at which they are disposed in the path and in positions at which they and the rest of their device do not interfere with the travel in the path of the boards. When in the out position, the leading device is adapted to stop the travel of such a board, and both devices are then selectively operable to grip and then release the stopped board. Sensors on the leading device are used to detect the presence of a board near to and at such device. A computer is responsive to such sensors and is used to produce a desired sequence of operations of such two devices and of other units.

摘要： A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024.times.1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user.In accordance with one enbodiment of the invention, a data ring communicates space division switch outlet availability to each of the data switching modules in turn, in order to resolve the contention among these modules for a particular outlet. Each data switching module maintains a list of outlets for which it has accumulated a group of at least one packet destined for that outlet; a data switching module then seizes an available outlet by marking that outlet unavailable in the data communicated by the data ring.

摘要： A novel logic gate, using Gallium-Arsenide technology, that is compatible with TTL or CMOS logic. This logic gate operates off a single voltage supply (e.g. 5 volts) and implements complex logic functions within a single logic gate, such as "AND-OR-INVERT". This is accomplished by having at least one FET with the gate terminal coupling to a current limiter, a first source/drain terminal coupling to the input of a logic sub-circuit, such as a DCFL circuit, and a second source/drain terminal coupling to the input of the logic gate. A diode disposed between the first source/drain terminal and the input to the logic sub-circuit sets the switching voltage of the logic gate. Parallel-connected FETs performs the logical "AND" sub-function while the logic sub-circuit performs the logical "OR" and "INVERT" sub-functions. Also disclosed is a buffer circuit for driving large loads while providing large output voltage swings.

摘要： Contacts comprising nickel and a glass-forming additive have electrical contact properties which render them suitable as replacements for gold contacts; disclosed contacts have low contact resistance even after prolonged exposure to an oxidizing ambient. The glass-forming additive is one or several of the elements boron, silicon, germanium, phosphorus, arsenic, antimony, or bismuth, and contacts are readily formed, e.g., as layers on substrates. A crystallographically disordered structure is produced in a contact surface layer at least upon exposure to an oxidizing ambient; alternatively, such desired structure can be produced by ion bombardment and even in the absence of glass-forming additives.

摘要： An emergency call service system, such as an E911 system, provides service system personnel with the addresses of abandoned calls to facilitate abandoned call follow-up. When a call comes in to a "911" ANI controller (21), the calling number is recorded. If the call is abandoned prior to being assigned by ACD 23 to an agent position (27-28) for being answered, an abandoned call ALI function (25) is invoked to obtain information pertaining to the calling number from a database (20), similarly to a non-abandoned call. When obtained, the information is displayed on equipment (29) such as a printer, terminal, or PC, to make it available to system personnel for use in following up on the call. The ANI controller serves both "911" emergency calls and emergency call-handling agents as well as other calls and other users, by switching the emergency calls to the agents and switching the other calls to the other users.

摘要： In a process for repairing electronic device packages, the problem of removing solder remnants on substrate bonding pads is solved by, first, etching a pattern in silicon and metallizing the pattern to make a silicon wick. The solder remnants on the bonding pads are melted, and the etched pattern of the silicon wick is brought into contact with the remnants to remove them by capillary action. It is often convenient to heat the silicon wick so that solder remnants melt when the wick is brought into contact with them.
