Abstract: An adaptive, tariff dependent traffic routing system, which controls routing of traffic and performs management of network resources in multi-node telecommu­nication networks, where the cost for a communication depends on the type of service provided and on the dis­tance between the originating node and the destination. Each node can originate traffic, receive and/or transit traffic over inter-node trunks. The system is realized by means of a central computer, which has connections to the SPC nodes of the network over two-way data links. The computer has access to data stored in the computer's memo­ry, containing the actual distance- and service sensitive tariffs applied in the network. By frequent scanning of the network, the computer has a global view of the actual out-of-service and traffic load status in the nodes and in the different trunk groups. Based on the tariffs and on the global network status view the system determines the policy for routing traffic in the network, such that the revenue is maximized. When determining the routing deci­sions, the out-of-service and overloaded network equipment is automatically by-passed. Similarly, traffic to out-of-­service, overloaded or hard-to-reach destinations is not allowed to enter the network. The same applies to traffic destined to access-restricted nodes. The routing policy is transmitted to the SPC nodes in terms of routing instruc­  tions, specific for each originating node and each destina­tion as well as specific for each type of a service. Since new instructions are issued after each network scanning, these will vary with the actual traffic and out-of-service situation in the network. In this way an adaptive, revenue maximizing traffic routing and network management system is achieved.

Abstract: In a machine for making two-part objects, for example a folding box blank with a window insert, the first parts are conveyed separately, essentially perpendicular to the conveying direction of the second parts and joined there to the latter. By means of special devices for adjusting both the first parts and the second parts, a simple transport device can be used, namely carriages, which seize the stacked second parts from a magazine, convey them over the first parts and deposit them there with precise positioning. The machine can operate in a particularly economical manner if such magazines are provided on either side of the assembly line and are served in a synchronously alternating manner by two such carriages which deposit the respective second parts alternately on the assembly line or the first parts conveyed there with precise positioning, where for example a gluing operation takes place. The machine can be used both as an independent machine and can easily be integrated in an assembly line in the case of products whose manufacture requires several work operations. In principle, the machine can process any first and second parts in which an exact relative positioning is required.

Inventor: ZDEBLICK MARK
IPC: F16K31/00
Filed: 1987-09-24
Abstract: There is disclosed herein an apparatus for converting control signals of an electrical or optical nature or any other type of signal which may be converted to a change of temperature of a fixed volume of material trapped in a chamber to flexure of a membrane forming one wall of the chamber. Typically, the device is integrated onto a silicon wafer by anisotropically etching a trench into said wafer far enough that a thin wall of silicon remains as the bottom wall of the trench. In some embodiments, polyimide is used as the material for the membrane. The trench is then hermetically sealed in any one of a number of different ways and the material to be trapped is either encapsulated during the sealing process or later placed in the cavity by use of a fill hole. Typically, a resistor pattern is etched on the face of pyrex wafer used as a top for the trench to form the cav­ity. When current is passed through this resistor, the material in the cavity is heated, its vapor pressure increases and expansion occurs. This causes the flexible wall to flex outward. This outward flex movement may then be used to either shut off a fluid flow path, or be sensed in some manner when using the device as a transducer. Typically, a fluid passageway having a nozzle aperture surrounded by a sealing surface is photolithographically   etched into a third wafer. This third wafer is then bonded to the first wafer such that the sealing surface is adjacent to the membrane such that when expansion in the cavity occurs, the membrane flexes until it contacts the sealing surface and shuts off fluid flow through the nozzle aperture. There is also disclosed herein a pres­sure regulator and a flow regulator each of which are integrated on a single die using the valve structure disclosed herein.

Abstract: Private providers of television programmes often have their transmissions radiated encrypted so that the interested party must use a pay decoder. The decoder then evaluates an unencrypted signature which must be correctly identified with respect to any noise on the transmission path. 
<??>To detect the signature, the invention uses a correlation circuit which is supplied with the signal components existing in the video signal and with a reference signal. The correlation circuit is followed by a threshold circuit in which the error rate is determined. When the rate drops below a predetermined error rate, the signature is detected as correct and the decoder is enabled. 
<??>The invention can be used in so-called pay TV systems.

Abstract: The invention relates to a high-resolution D/A converter using an amplifier with a gain programmed in L + 1 steps and with selection of a corresponding gain step. The object is to achieve a higher resolution than that given solely on the basis of the number of bits. The aim is achieved by multiplying the digital input signal by a gain factor Sl, in such a manner that the word length of the signal to be converted is reduced, avoiding any overflow. This is followed by a digital/analog conversion. The converted analog signal is then reduced by the gain 1/Sl which is equal to the inverse value of the multiplication factor Sl at the input. The field of application is the audio signal processing in sound studios. <IMAGE>
