Systems and methods can provide, in one aspect, a method for modulating the pulse width of control signals generated on a plurality of separate channels. In one practice, the methods described herein are suitable for execution on a microprocessor or micro controller platform that includes a timer interrupt mechanism which will generate an interrupt in response to a timer counting down a selected time interval or time period. In one practice, the timer is set to count down a period of time that is representative of a portion, or sub period, of the PWM cycle. Upon expiration of that time period, the timer executes an interrupt that causes the micro controller to enter an interrupt service routine (ISR) that can further modulate the PWM cycle of one or more signals.

Over-terminating the differential mode impedance of a differential transmission line, such as an INFINIBAND™ cable, at the receiving end, improves the differential signal integrity for typical variations in termination network impedance component (e.g., resistor) and transmission line characteristics. Eye opening of the differential signal can be made larger with reduced attenuation but increased jitter compared to under-terminating the differential mode impedance. Because the differential signal quality (larger eye opening) is improved, data can be transmitted over a longer transmission line with the same transmitter and receiver.

A simulation system is described for computing the overall signal generated in a substrate by a digital system comprising a plurality of gates associated with the substrate, wherein each gate is configured to perform a switching event. Output of a transistor-level model is compared with output of a lumped circuit model for each gate and the substrate, and signal contributions from each gate and switching event are determined based on the comparison. The system determines switching event signals for each of the plurality of gates. The signal contributions and the switching event signals are combined, and a combined lumped circuit model is derived based on a combination of lumped circuit models of the plurality of gates. The overall signal is computed based on the combined gate signal contributions and switching event signals, which are configured as an input to the combined lumped circuit model.

A mapping function and method for mapping a Signaling System 7 (SS7) telecommunication signaling message from a Signaling Connection Control Part (SCCP) protocol layer to an Internet Protocol (IP) protocol layer in order to transmit the SS7 signaling message over a data network from an origination node to a destination node. The mapping function receives the SS7 signaling message from the SCCP protocol layer by sending and receiving Message Transfer Protocol (MTP) primitives from the mapping function to the SCCP protocol layer. The mapping function then maps the received SS7 signaling message into an IP message by mapping MTP primitives into IP primitives, mapping the SS7 message address into an IP message address, and utilizing a user interface to set IP protocol parameters that cannot be transferred by the SCCP protocol layer. The mapping function then sends the mapped IP message to the IP protocol layer by sending and receiving IP primitives from the mapping function to the IP protocol layer.

Systems, devices and methods provide for evaluation of heart failure symptoms. Sensor data associated with one or more symptoms of heart failure are acquired and trended. Statistical features, such as slope, are extracted from the data trend in a moving window and are used to develop a cumulative sum. The cumulative sum is compared to a threshold value or V-mask to detect a shift in cumulative sum indicating changes in heart failure symptoms. A shift beyond the threshold value may trigger an alert or implementation of therapy.

System and method of estimating radio channel bit error rate (BER) in a digital radio telecommunications system wherein the soft output of the turbo decoder is used as pointer or index to look-up-tables containing the bit-wise BER of a certain bit in the data field of the received frame. A quantizer quantizes the received data frame and the quantized bit operates on a switch which selects the appropriate look-up-table. By means of accumulation and scaling the average BER of a certain amount of bits are calculated. Decoding bit-errors may occur but as they are submitted to posterior probability estimation, systematic errors which normally happen at low SNR are avoided.

A signaling message processing and routing node intercepts and routes signaling system 7 (SS7)-based signaling messages received from the base station controller (BSC) component of a base station system (BSS) via an A-interface link interface. The A-interface normally connects a BSC node to a mobile switching center (MSC) node. Upon determining that a signaling message received from a BSC node via an A-interface link is an SMS-related message, the SMS message is routed towards the appropriate destination without involving the MSC node connected to the BSC. The SMS message may be encapsulated within an Internet protocol (IP)-based transport adapter layer interface (TALI) protocol packet and transmitted into an IP network. As a result, MSC resources are conserved.
