Abstract: The present invention is directed to a method and system for detecting a wireless telephone communication in a vehicle, and once detected, when the vehicle exceeds a predefined speed limit, for generating and sending Dual-Tone Multi Frequency (DTMF) encoded information over the voice channel. The encoded information comprises the values of various physical parameters related to the moving vehicle. For instance, these parameters can include the current time at which the telephone communication started, and optionally, the position of the vehicle. In a particular embodiment, the values of the various parameters are sent at regular time intervals until the communication terminates.

Abstract: Under the present invention, a state machine representation is used to encrypt/decrypt a message of data values. The state machine representation includes a plurality of nodes, wherein each of the data values are assigned to at least one of the plurality of nodes, wherein each of the plurality of nodes includes one or more transition vectors that each have a unique value, and wherein each of the one or more transition vectors starts from one of the plurality of nodes and leads to another one of the plurality of nodes. To encrypt the message, a sequence of transition vectors is traversed from a start node. As the transitional vectors are traversed, the corresponding unique values are recorded in sequence. When one of the data values is encountered at a node, a random number is generated and recorded in the sequence. Once all data values have been encountered, a string of the recorded unique values and the random values is outputted to a recipient.

Abstract: Methods which determine network performance by determining not only the transit delay between nodes in a network but also the variance, or jitter, of such transit delays. A common node, usually a network management computer (NMC), sends out a signal to a first node of interest and measures the time before it receives an acknowledgment from the first node. The NMC then sends out a similar signal to a second node of interest and similarly measures the time required to receive an acknowledgment. Based on these two measurements, the transit delay between the first and second nodes can be calculated if the first node lies on the path between the NMC and the second node or vice versa. For a multiple node communications path, the total transit delay between any two nodes is the sum total of the transit delays between adjacent nodes lying on the path.

Abstract: A system, method and program product that implement a design object that automatically provides compliance to alternating phase shifted mask (altPSM) rules are disclosed. The invention implements a design object that is used during layout to indicate a phase-shiftable design feature in the layout. Each design object includes a base shape indicative of the feature to be ultimately created and two different type phase shape identifiers that identify the requisite mask area and color of phase-shift required for that base shape. Each phase shape identifier is assigned to a portion of the base shape. During layout, overlapping placement of design objects is not allowed if the placement requires overlapping phase identifiers of the same type. Alternatively, placement is allowed where the phase identifiers of different type are separated by a minimum distance from each other defined by a buffer of the design object.

Abstract: A method, system and program product for merging cloned and original circuit shapes such that a union thereof does not include a notch. The invention determines, for a cell including an original circuit shape and at least one overlapping clone of the original circuit shape, whether each clone corner point of each overlapping clone is within a threshold distance of a corresponding original corner point of the original circuit shape; and generates, in the case that each clone corner point of each overlapping clone circuit shape is within a threshold distance, a union of each overlapping clone and the original circuit shape such that the union does not contain a notch. The union is generated using a point code that sets a new position for a union corner point to remove a notch based on the original shape's direction and the edge orientations previous to and next to the corner point.

Abstract: A method, system and program product that implements area minimization of a circuit design while respecting the explicit and implicit design constraints, in the form of ground rules and user intent. A longest path algorithm is used to generate a scaling factor. The scaling factor is used to reduce the size of the circuit design to the minimum legal size.

The resulting design is shrunk (or expanded) with all elements shrinking (or growing) together by the same factor, and with the relative relationships of elements maintained. In addition, the invention is operational in the presence of a positive cycle, can be run with scaling that freezes the sizes of any structure or ground rule, and can be applied to technology migration.

Abstract: A method, system and program product for creating a simplified equivalent model for an IC that can be used for detailed analysis. The equivalent model takes into consideration the effects of all the I/O placement regardless of the non-uniformity of I/O placement. The equivalent model is generated, in part, by partitioning the IC into simulation windows and converting I/Os within each simulation window to a current source having the same current change rate, and then running a simulation on this intermediate model. A current change rate observed for a simulation window is then used to convert back to actual I/Os to create the equivalent model. The equivalent model can be simulated using conventional software, e.g., SPICE, for more detailed analysis such as signal integrity, timing of I/Os and noise.

Abstract: Combining of reference measurement collections (RMCs) of at least three reference measurement systems into a weighted reference measurement collection (wRMC) is disclosed. Each RMC includes a plurality of corresponding sample measurements, each of which has a measurement value of the same sample. The invention plots corresponding measurement values to generate a plurality of data pairs for each possible RMC pairing. A best-fit line of the plurality of data pairs for each RMC pairing is then generated, and a residual for each data pair is calculated. A weight is then assigned to each sample measurement for each RMC based on the residuals associated with a respective RMC to which the sample measurement belongs, favoring a smaller residual more than a larger residual. A weighted reference measurement is then generated based on the weights, and the measurement value for the respective sample measurement for each RMC.
