Abstract: A glitch-free clock switch circuit for an integrated circuit having a plurality of asynchronous clocks, wherein only one clock is selected at a time, and wherein the clock switching circuitry for switching from a currently selected clock to an inactive clock to next be selected is activated only for the time it takes to complete the switching. The clock switch circuit includes at least three sets of clock drivers, wherein each set is comprised of two drivers and separate clock drivers are each associated with the output clock, the currently selected clock and the clock to next be selected, respectively. An edge detector turns on these clock drivers in response to a clock select signal, and a set of synchronizers receive and synchronize the clock select signal first with the output clock and then with the currently selected clock and the clock to next be selected, respectively.

Abstract: Hardware-software co-synthesis of an embedded system architecture entails partitioning of its specification into hardware and software modules such that its real-time and other constraints are met. Embedded systems are generally specified in terms of a set of acyclic task graphs. For medium-to-large scale embedded systems, the task graphs are usually hierarchical in nature. The embedded system architecture, which is the output of the co-synthesis system, may itself be non-hierarchical or hierarchical. Traditional non-hierarchical architectures create communication and processing bottlenecks, and are impractical for large embedded systems. Such systems require a large number of processing elements and communication links connected in a hierarchical manner, thus forming a hierarchical distributed architecture, to meet performance and cost objectives.

Abstract: Disclosed is an antenna structure for transmitting and receiving electromagnetic signals, in particular for mobile telecommunication using the GSM Standard. The antenna structure allows for decoupling between the transmission path and reception path. The antenna structure has two preferably perpendicular couplings with two separate ports, for example for the connection of a transmitting device and a receiving device. Furthermore, the impedances of the two couplings can advantageously be matched, independently of one another, to the transmitting device and receiving device and/or the frequency bands of the signals to be transmitted or received.

Abstract: An NPA split management system and associated methods for receiving from a user descriptive instructions regarding an upcoming NPA split, and responsively updating components of the Intelligent Network to reflect corresponding changes in the NPA codes assigned to lines, subscribers, services, etc. A user interface operating in conjunction with a Service Management System allows the user to declare an NPA split and define its characteristics, including the old NPA code, the new NPA code, the central office codes to be “transferred” to the new NPA, and the dates of beginning and end of the permissive dialing period (PDP). The SMS contains indicia corresponding to SMS-managed databases, or tables, records, or fields thereof, which definitively specify whether the data contained therein is affected by an NPA split. The SMS determines which items require updating to the new NPA code, and on which components the affected databases or services reside.

Abstract: An optical fiber connector that is tunable despite being fully assembled has a assembly having an enlarged ferrule holding member or flange that has a multi-faceted periphery, preferably in the shape of a hexagon. The connector has a front housing portion that has a multi-faceted seating region for the flange. The flange is disengageable from the seating region for tuning rotation by being movable axially toward the rear of the housing against the force of a spring. The connector can be tuned by incremental rotations of the assembly when the flange is disengaged.

Abstract: A dual seal system for retrofitting existing vapor deposition apparatus for starter tubes has a first tubular member which surrounds the chemical vapor delivery tube and forms a channel therewith for passage of starter tube gases to a stationary seal coupling member which, in turn, is connected to monitoring apparatus. A second tubular member surrounds the first tubular member and forms a passage therewith extending from behind a seal assembly in the starter tube to a bore in the coupling member connected to a buffer gas supply. The second tubular member also forms a third passageway with the interior wall of the arbor driving the starter tube and is held spaced therefrom by a perforated support member. The third passageway extends from a region behind the sealing system to a sealed buffer chamber in the coupling member, which is connected to a low pressure of vacuum source and to a pressure monitoring member.

Abstract: An apparatus, method and system are illustrated which provide for personal telecommunication incoming call screening and alerting. In the various embodiments, the incoming call screening and alerting utilizes a personalized affinity database, based upon individual calling behaviors and patterns. In the preferred embodiment, the affinity database includes telephone numbers and names for outgoing calls (dialed numbers), and for those incoming calls that have a predetermined minimum duration following answering (minimum off hook time period). As a consequence, erroneous or unwanted incoming calls are not included within the affinity database. The preferred system includes a line unit couplable to customer premise equipment (such as a telephone), a network signaling interface, a network trunk interface, a memory, and a processor.

Abstract: A packet filter method and apparatus for a router employs an algorithm that decomposes a set of n filter rules of a k-dimensional space into sets of rule segments associated with non-overlapping intervals in each dimension. Such packet filter may be employed for layer four switching applications. Bit-parallel processing may be employed to compare each interval with corresponding fields of a packet received by the router. Bitmaps defined by the sets of rule segments, and so related to the corresponding filter rules are associated with the intervals. The interval bitmaps are combined to form a filter rule bitmap that identifies and associates one or more filter rules with the packet.

Abstract: Intelligent memory devices allow for the transfer of data between two or more electronic devices, such as digital signal processors and microcontrollers. The memory devices may be designed as dual port memory devices capable of sending/receiving synchronous, serial data. The use of serial data reduces the pin count of the memory devices and those connected to it. The memory devices also utilize a dedicated pair of data bits and memory pointers to carry out management of the memory and data transfers allowing connected devices to reduce the amount of processing time spent on such matters.

Abstract: A method for preparing a chemical mechanical polishing apparatus for polishing product substrates includes polishing designated “warm-up” substrates until polishing pad characteristics have achieved steady state conditions. The reusable warm-up substrates may be formed of a mechanically resistant material or a material having substantially the same removal characteristic as the product film to be polished. The reusable warm-up substrates may also be formed of a mechanically resistant film formed over a semiconductor substrate. The polishing pad characteristic of pad compression may be determined using a previously established correlation or it may be measured.

Abstract: A method of generating a motion vector associated with a current block of a current frame of a video sequence includes searching at least a section of a reference frame to identify previously reconstructed samples from the reference frame that best estimate motion associated with previously reconstructed samples from the current frame associated with the current block. The previously reconstructed samples may form sets of samples. Such sets may be in the form of respective templates. The method then includes computing a motion vector identifying the location of the set of previously reconstructed samples from the reference frame that best estimates the set of previously reconstructed samples from the current frame associated with the current block. It is to be appreciated such a motion estimation technique is performed in both a video encoder and video decoder so that motion vector data does not need to be transmitted from the encoder to the decoder.
