Abstract: An electronic device for decoding a navigation data by using a phase angle variation and a method thereof are described, which includes the following steps. A phase angle difference between the first phase angle of the first navigation data and the second phase angle of the second navigation data from a satellite signal is calculated. When the phase angle difference is greater than 90 degrees, the first navigation data and the second navigation data are determined to have opposite signs. The second navigation data according to the first navigation data and the result is determined. Therefore, each data is interpreted through directly comparing whether the phase angle difference with the previous data is greater than 90 degrees or not, so that the correct rate in decoding the navigation data is increased.

Abstract: A transaction entity handles event messages associated with events of interest. At least one type of event is identified that is of interest to a user. Each type of event further corresponds to an event type that is to be repeated by a transaction entity to an aggregating entity. Further, a description is associated with each identified type of event. The transaction entity identifies an occurrence of an event that is an identified type of event and generates an event message comprising a token that associates the user with an account maintained by the aggregating and the description that is associated with the identified type of event corresponding to the identified occurrence of the event. The event message is transmitted to the aggregating entity.

Abstract: A semantic database transaction monitor is provided that monitors database transactions by taking advantage of database replication technology. The invention receives one or more event streams of transaction data from one or more database replication software agents, originally from transaction logs, and then classifies each transaction, utilizing an inference engine populated with one or more source ontologies and a canonical ontology so that transaction metadata are normalized. The invention then can be utilized to create a data store across multiple databases for reporting and analysis. The invention can also be used to feed normalized database transactions to real-time graphics software for real-time reporting or alerting. Because the process obtains data from event streams, it does not significantly drain the resources of the databases and can provide virtually real-time monitoring. Moreover, it does not require recoding for updates to the databases, but only changes to the ontologies read at runtime.

First, a coordinate of the image pickup device and a coordinate of the shot object are obtained at a first time point. Next, a coordinate of the image pickup device and a coordinate of the shot object are obtained at a second time point.

A moving speed of the shot object is calculated according to a time difference and the moving distance. Afterward, the obtained moving speed is displayed on the image pickup device, such that the user knows about the moving speed of the shot object.

Abstract: A method for calculating current position coordinate is applied to a global positioning system (GPS) receiver. When positioning at a current time point, the GPS receiver directly calculates a code delay and a carrier frequency of each satellite and position coordinate of the GPS receiver at a current positioning time point by utilizing an ephemeris data of each satellite and position coordinate of the GPS receiver at a last positioning time point, thereby greatly lowering an operation amount, so as to reduce the power consumption.

Abstract: A method for obtaining correct phase inversion points in a signal of global positioning system (GPS) includes the following steps. A satellite signal from one of a plurality of satellites is received continuously. A plurality of phase inversion points in the received satellite signal is interpreted. Each time difference between each two adjacent phase inversion points among the plurality of phase inversion points is calculated. It is determined whether each of the time differences is an integral multiple of 20 milliseconds. A data is retrieved every 20 milliseconds from the satellite signal by using a first phase inversion point in the plurality of phase inversion points as a starting point when each of the time differences is an integral multiple of 20 milliseconds. By finding out a plurality of correct phase inversion points in the satellite signal, the positioning speed is increased, and thus a positioning time required is reduced.

Abstract: A smart node is integrated with each Web service in a Web service application chain to automatically supply compatible features, missing functionality, and orchestration of the processes in the application, without coordination by an orchestration engine, in an embodiment. A smart node is a software program that systematically specifies the communications dimensions, functionality, and orchestration required for interoperability among Web services. The communications parameters, backup functionality, and process orchestration required for the Web services in a Web service application may be predetermined and programmed into smart nodes. The smart nodes are subsequently integrated with the Web services in a Web service application so that communications among the Web services occur first through the smart nodes. The smart nodes can thus supply communications parameters, any missing functionality, and dynamic process orchestration based on the current event context of the Web service application.

Alternatively, the signature may include sound waves emitted from the data entry device and the masking may include masking sound waves emitted from the data entry device to reduce the detectability of the sound waves. A system may also be employed for protecting data entry to a data entry device from eavesdropping.

Abstract: A computer processing device receives computer readable data to derive computer executable rules for mining and constructing situation categories. The received data is transformed into a predetermined standard format if the received data is not already in the predetermined standard format. The predetermined standard formatted data is parsed, and an outer, iterative loop is performed until at least one predetermined stopping criterion is met. An inner iterative loop is performed within the outer iterative loop until all desired subsets of data are processed. During the inner iterative loop, selected subsets of data are labeled with labels associated with corresponding previously labeled subsets of data. New computer executable rules are generated for mining and constructing situation categories from the labeled subsets of data. Keyword list classifiers are transformed using the stored labeled subsets of data.
