摘要： The present invention reduces a signaling size of an interference overload indicator. A base station includes an interference-overload-indicator generation control sub-system (1000), an interference-overload-indicator generation sub-system (2000), and a transmitting/receiving sub-system (3000). The interference-overload-indicator generation control sub-system (1000) judges whether or not a condition to initiate interference indicator generation is satisfied, and activates the interference-overload-indicator generation sub-system (2000) only when the condition is satisfied. This makes it possible to reduce a signaling size of the interference indicator. For further reducing the signaling size, an interference indicator signaling is generated by a method such as differential coding, state coding, or a bitmap, and transmitted. According to the present invention, an interference overload indicator generation control mechanism is relatively simple and the signaling size of the interference indicator is small.

摘要： An embodiment of an optocoupler may provide electrical isolation between signals on a driver side and signals on a receiver side of the optocoupler by generating light signals via a fiber-optic link to the receiver. One embodiment includes driver circuit that may receive an input signal (or a series of input signals) having a specific clock cycle. Instead of driving a light source, such as a light-emitting diode, for the entire duration in which an input signal may be at a high logic level, the LED may be driven with only a pulse to indicate any transitions from high-to-low or from low-to-high. In another embodiment, a receiver circuit may then interpret pulses of differing widths to reconstruct a series of logical signal from only its pulse transitions. By limiting the amount of time in which the LED is on, yet still conveying all underlying data in the input signal, the optocoupler reduces the overall power needed during operation.

摘要： A pattern recognition system, pattern recognition method, and pattern recognition program capable of increasing the accuracy in computing the false acceptance probability and capable of ensuring a stable security strength are provided. Pattern recognition systems 10 and 10a comprise a first probability computation unit 32, and a second probability computation unit 33 coupled to the first probability computation unit 32. The first probability computation unit 32 computes a first probability PFCR based on the number n of corresponding characteristic points cs1 to csn and cf1 to cfn indicating points corresponding between characteristic points s1 to sns in a first pattern and characteristic points f1 to fnf in a second pattern. The first probability PFCR indicates the probability of existence of a third pattern that has a greater number of corresponding characteristic points to the first pattern than the number n of the corresponding characteristic points. The second probability computation unit 33 refers to the first probability PFCR to compute a false acceptance probability PFAR indicating the probability of falsely determining that the first pattern and the second pattern correspond to each other.

摘要： A line-based digital halftoning technique uses both a wavelet transform and multi-scale dot assignment concepts in which the dots are assigned in a top-down fashion and error diffusion is also adopted to fine tune the halftoned images and compensate for errors generated by the implicit quantization. 1-D processing makes the implementation easy while the top-down multiscale dot assignment can produce a multi-resolution halftoned image, which provides a good approximation of the original in multiple scales.

The part of the multi-path framework includes a symbol grouping and recognition component that is designed to group input strokes that correspond to a handwritten mathematical expression into a symbol and to recognize the symbol based upon information associated with the grouped input strokes. A method for grouping and recognizing symbols of a handwritten mathematical expression includes receiving a plurality of input strokes corresponding to a handwritten mathematical expression, grouping the plurality of input strokes into symbols, recognizing the symbols based upon information, such as shape and time series information, associated with the grouped input strokes. Intra-group and inter-group information associated with the plurality of input strokes may be utilized to group the input strokes.

摘要： There is provided herein cross-linked, phosphorescent micro- and nanoparticles and applications of those particles. The invention uses halogen-containing polymers and co-polymers (HCPs) as an encapsulation matrix for organic and organometallic phosphorescent compounds to form micro- or nanoparticles. The phosphorescence of these encapsulated phosphorescent particles is substantially unaffected by phosphorescence quenchers such as oxygen and water molecules at ambient conditions. The invention provides methods of making cross-linked phosphorescent particles. HCPs may be directly cross-linked through linking moieties that are a part of the polymer, or cross-linked through other separate bridging or cross-linking materials Cross-linked particles are more stable than the non-cross-linked counterparts and more resistant to temperature, surfactants, and organic solvents.
