The invention discloses a detection method of direct current arc faults. The method is characterized by acquiring and computing a plurality of arc phenomena detection periods, confirming the arc phenomena, namely spark discharge phenomenon and arc discharge phenomenon by two feature extraction methods including a time domain standard deviation method and a Mahalanobis distance method based on time and frequency domains and counting the two phenomena respectively, and in the primary arc fault diagnosis period, judging that the arc faults exist if the total count of the two phenomena exceeds the given threshold and needing to judge whether suspected arcs appear if the total count of the two phenomena still fails to exceed the given threshold beyond the time.

A method for detecting an undesirable condition within a messaging network. A message is received and a source of the message is identified. If an entry in a database for the source has not been created, an entry is created. A source counter for the source is then set to one and a timestamp is created for the source. If an entry in the database for the source has been previously created, the source counter is incremented by one and the timestamp is updated. The source counter is then compared to a source threshold, and if the source counter exceeds the source threshold over the course of predetermined amount of time, a source alarm is triggered. A sliding with respect to the predetermined amount of time may also be implemented to account for total counts that may fall across or be split by set periods of time. The invention is particularly useful for detecting “spam” events and undesirable routing loops.

A method, a system, and a computer program product for determining a total count of audience members within a sensory receiving environment during the presentation of a program. A voice recognition unit is enabled when a signal for a program / subject / event, such as a broadcast program, is received. The voice recognition unit receives one or more sounds in the sensory receiving environment and analyzes the characteristics of the sounds. When one or more unique human voices are identified during the program, a count of the number of unique human voices is determined. The count of unique human voices is transmitted to a server, whereby the count of unique human voices is equal to a count of audience members. The total count of audience members is calculated for all sensory receiving environment associated with the program. An audience analysis graphical user interface is generated to display the total count of audience members.

A topological best match naming convention apparatus and method for graphical user interface (GUI) testing are provided. With the apparatus and method, properties of the GUI object are recorded and stored in a GUI object database. During execution of test scripts, if a lookup of an GUI object's name to its runtime control fails, the present invention attempts to perform a match with the currently known objects.

A correspondence between a GUI object and a known GUI object having a highest total weight is selected as a best candidate for use in determining the runtime control for the GUI object.

The invention discloses a method for open-loop measurement of a radon exhalation rate by utilizing a total count of 218Po and 214Po. The method comprises the following steps: a radon collection cover is buckled on the surface of a medium to be measured during measurement, clean air with the radon concentration of near zero is continuously pumped from outside by utilizing a pump of a radon measuring apparatus, and the radon exhalation rate can be obtained by measuring a radon concentration change rule in the radon collection cover.

A plan for a power network for an integrated circuit device is automatically preparing in two stages. In a first stage, a number of simplified plans are prepared on a global scale, without regard to design rule checking constraints and routing blockages. Next, the simplified plans are evaluated to select a plan that conforms to a user-specified limit for an attribute, such as maximum voltage drop. The selected simplified plan, which identifies a total count of power wires and a width of the power wires, is used in a second stage to prepare a more detailed plan that honors the design rule checking constraints and routing blockages. The detailed plan is evaluated to check for conformance with the user-specified limit on the attribute, and if necessary the detailed plan is changed, e.g. by increasing wire width one or more times, to achieve conformance.

In a communication network, end-user systems are connected via a common transmission medium to a timeslot assignment unit. Each end-user system has a buffer for storing packets, and a queue length detector for detecting a queue length of the stored packets. The end-user system forwards packets on assigned timeslots to the network and transmits a signal for indicating the detected queue length to the assignment unit. The timeslot assignment unit maintains timeslot records to store count numbers of assigned timeslots, determines a total count number of timeslots assigned to each end-user system during a period corresponding to the delay time of the unit, and receives a queue length signal from each end-user system. From the total count number and the queue length a virtual queue length is determined for indicating the number of packets to which timeslots are still not assigned. Based on the virtual queue length, timeslots are assigned to each end-user system.
