Abstract: A fault signalling system for an optical fiber-based communications link having erbium doped fiber amplifier repeaters comprises a broadband optical source for generating a fault signal in the event of a fault occurring. Each repeater includes such a broadband source, which will output a characteristic fault signal onto the link for transmission to a receiving station, in the event of a fault being detected at that repeater. Advantageously, a control circuit which enables the source to emit its fault signal when appropriate is also used as part of an automatic gain control for the output of the amplifier repeater in normal operation.

Abstract: Each of the remote high speed circuits of a digital system is provided with a sync pulse generation circuit for generating periodic sync pulses with a predetermined periodicity using a control value. Additionally, each of the remote high speed circuits is further provided with a sampling circuit for sampling the sync pulse generation control value, a comparison circuit for determining whether each of the sampled sync pulse generation control values are consistent, and an adjustment circuit for adjusting the sync pulse generation control value of the particular remote high speed circuit. Furthermore, a sync pulse generation coordinator comprising a clock selection circuit, a delay line, a delayed clock selection circuit, and a coordination pulse generation circuit is provided to the digital system for generating periodic coordination pulses. The periodic coordination pulses are used to control the sampling and comparison. A different delayed reference clock is used to generate the coordination pulses to control the sampling and comparison until a delayed reference clock that leads to consistent samples of control values for all remote high speed circuits is found. Once consistent sampling results are achieved, the sync pulse generation control values of the remote high speed circuits are adjusted accordingly using the adjustment circuits. The process is repeated until all sampled results are consistent and synchronized. The sampling is then continued to monitor for loss of synchronization.

Abstract: An address converter that reduces the number of address bit changes between successive sequential addresses is provided to a RAM address bus for a sequentially accessed RAM. In the presently preferred embodiment, the address converter comprises a plurality of XOR gates for converting the access addresses into gray coded access addresses having at most one address bit change between successive access addresses. As a result, the power consumed and the noise generated over the address bus is reduced, thereby conserving power available and minimizing device package pins required by the digital system having the RAM and the RAM address bus.

Abstract: A digital clock reconstruction circuit comprising a first flip flop, a programmable delay chain, and a first assembly of gates is provided to digitally compensate an entering digital clock's skew for a high speed digital circuit by digitally reconstructing the entering clock. The reconstructed clock will also provide the minimum amount of high and low time in a period required by the components of the high speed circuit. Additionally, at least one measurement or comparison circuit is provided for measuring the frequencies of the reconstructed clock under various delay settings of the programmable delay chain to calibrate the digital clock reconstruction circuit. Under the calibration process of the present invention, the delay setting is determined iteratively, starting from an initial setting and varying the delay setting in a predetermined manner. In the preferred embodiment, a ring oscillator is also provided to guide the selection of the starting delay setting, and multiple measurement and comparison circuits are provided. The measurement and comparison circuits are used to collect various measurements to monitor the digital clock reconstruction circuit during normal operation as well as calibrating the circuit. Furthermore, the digital clock reconstruction circuit is provided with an additional flip flop and gate assembly to generate an additional reconstructed clock. The additional reconstructed clock is periodically monitored during normal operation to provide early warning to the fact that the reconstructed clock period is drifting from 50% duty cycle symmetry.

Abstract: A decorative container device is disclosed that provides a multipurpose, weatherproof storage container for safely securing mementos at a gravesite. The decorative container device comprises a body component that is configured in a rectangular shape that measures approximately six inches in length and width and one to two inches in thickness. The body component would be a transparent, plastic structure that enables decorations like holiday cards and artwork to be seen through the container's surface. The body component also comprises hook and loop fasteners that allow the body component to be secured to a tombstone. Thus, each container device functions as a suitable way of showing affection to a loved one who has passed through different types of decorations inserted into the container.

Abstract: Systems and methods for braking and releasing one or more pivot joints used in an X-ray positioning device are described. The systems and methods use a support arm that extends between a main assembly of the x-ray positioning device and an X-ray imaging assembly with an X-ray source and an X-ray detector that are disposed nearly opposite to each other. The support arm includes one or more pivot joints (such as horizontal, lateral, and/or orbital pivot joints) that allow the imaging assembly to move with respect to the main assembly. The pivot joints can each be connected to an automated braking system that is capable of selectively locking and unlocking a corresponding pivot joint, as indicated by a user-controlled switching mechanism. The braking systems containing multiple pivot joints can be individually controlled by separate switching mechanisms or simultaneously controlled by a single switching mechanism. Other embodiments are described.

Abstract: Systems and methods are provided for improving prediction of credit risk performances of a plurality of consumers, each consumer having a standard credit data file and score. According to a particular aspect, a method determines changes in credit data files of the plurality of consumers during a predetermined period of time, and combines change data with standard credit data. The method determines a set of credit elements that are predictive of credit risk performances of the plurality of customers by processing the combined change data and standard credit data, and identifies an incremental risk value for each of the plurality of consumers by supplementing the corresponding credit data file with the predictive set of credit elements. The method further generates a flag indicative of the identified incremental risk value for each of the plurality of consumers.
