Abstract: A system and method provide functionality for collecting user update reports of geographic inconsistencies between geographic data and the real world to enable automated processing of updates to the geographic data. A user's input is collected and describes an anomaly, which is a geographic inconsistency between geographic data and the real world. The user's input is stored as language neutral structured data that enables automated processing of updates to the geographic data. Automatic processes that process the structured data include an email agent, an incident agent, a geographic augmentation agent, a case generation agent, a clustering agent, an automatic validation agent, and a monitoring service. Automatic and manual processes combined together handle processing of anomalies, as well as other related processing, and ultimately handle processing of updates to the geographic data to resolve the anomalies reported by the users.

Abstract: A system and method of providing multiple participants with a centrally accessible content portal for geographic point of interest (POI) data, for subsequent use in creating map-based or spatial applications. Different entities can dynamically upload, update, retrieve, and use digital map and POI data. Additional features include the ability to handle the large amounts of POI data needed by multiple Application Developers, including data that is dynamic, or frequently changing; the ability to update POI attribute information and deliver it to the Application Developers; the ability to associate multiple points of entry (POE) with a POI, and to aggregate data from multiple Content Providers; and the use of a common geocoding engine and common digital map reference across all Content Providers, which ensures the consistency of the geocoding throughout all the POI data.

Abstract: A method of generating a pulse width modulated (PWM) signal receives digital demand data comprising at least one more significant bit and at least one less significant bit. The PWM signal comprises a sequence of one or more frames, each frame comprising a plurality of PWM pulses whose duty cycle is substantially governed by the at least one more significant bit. At least one of its PWM pulses is selected to have its duty cycle modified in response to the at least one less significant bit. Each of the at least one less significant bit uniquely mapping onto the at least one selected PWM pulse of the frame. An apparatus operable according to this method includes an optical attenuator whose optical attenuation is dependent upon its temperature and in which the temperature and, hence, the attenuation is controlled using the above PWM signal.

Abstract: The present invention provides an optical attenuator comprising an optical attenuator module, an optical splitter, a detector and a control unit. Input radiation (Pi) is received at the attenuator module which is operable to attenuate the input radiation to generate corresponding attenuated radiation (Po). The detector is operable to receive a portion of the attenuated radiation (0.1 Po) and generate a corresponding electrical signal T1. The signal T1 is applied by the control unit via a first feedback loop to regulate the attenuator module so that radiation power of the attenuated radiation is maintained to a predetermined level. In a situation where an interruption of the input radiation (Pi) occurs, the control unit is operable to monitor temperature of the attenuator module using a thermistor sensor and to regulate the temperature of the module using a second feedback loop to a predetermined temperature during the interruption.

Abstract: According to the present invention, an apparatus and method for processing date fields in computer systems without the negative implications of the turn of the century problem is disclosed. The proposed solution is known as the "system encapsulation" method. In a preferred embodiment of the present invention, the code for the application software running on the computer system is not modified in any way. Instead, the preferred methods of the present invention modify the date-dependent information in the computer system database files and resets the system clock by adding or subtracting a certain number of "offset" years from the dates being processed by the system (for example, 28 years). The two-digit date representations in the modified database contain both positive and negative two-digit date representations, allowing the processing of data that spans 199 years and covers portions of three different centuries. This approach allows the application software to process the date-dependent data normally.
