20090310499 | DATA COMMUNICATION WITH CONTROL OF THE TRANSMISSION RATE OF DATA - A data communication network, includes a transmitting node; a receiving node; and a connection between the transmitting node and the receiving node. The receiving node is arranged to process data received from the transmitting mode via the connection. The network further includes a first measuring unit which is connected with a measuring input to the receiving node. The first measuring unit can determine a first parameter value forming a measure for the data processing capacity of the receiving node. A calculator has an input connected to an output of the measuring unit and can derive from the first parameter value a second parameter value forming a measure for the transmission rate of data from the transmitting node to the receiving node. A transmission control unit has a transmission control input connected to a calculator output and a transmission control output connected to the transmitting node. The transmission control unit can control a transmission of data via the connection based on the determined measure for the transmission rate. | 12-17-2009 |

20150356360 | SYSTEM AND METHOD FOR SUPERIMPOSED HANDWRITING RECOGNITION TECHNOLOGY - A system and method that is able to recognize a user's natural superimposed handwriting without any explicit separation between characters. The system and method is able to process single-stroke and multi-stroke characters. It can also process cursive handwriting. Further, the method and system can determine the boundaries of input words either by the use of a specific user input gesture or by detecting the word boundaries based on language characteristics and properties. The system and method analyzes the handwriting input through the processes of fragmentation, segmentation, character recognition, and language modeling. At least some of these processes occur concurrently through the use of dynamic programming. | 12-10-2015 |

20080284632 | PHASE DOMAIN ANALOG TO DIGITAL CONVERTER - An analog to digital converter that first converts an analog input voltage into first and second periodic signals having a phase difference there between that is a function of the analog input voltage and then introduces the first periodic signal into a forward direction data path through a series of consecutive delay cells so that the first periodic signal propagates through the cells via the first series of delay elements in a first direction, and introduces the second periodic signal into a reverse direction data path through the same series of delay cells so that the second periodic signal propagates through the cells via the second series of delay elements in an opposite direction, and using the second periodic signal to latch the first periodic signal in each cell so as to generate an output signal for each cell, said output signals of said cells collectively indicating the unique cell in which the leading edges of corresponding pulses in the first and second directions met, and decoding the outputs of the cells to generate a digital binary output value. | 11-20-2008 |
20090097601 | MULTI-DYNAMIC MULTI-ENVELOPE RECEIVER - The present invention is a system and a method of filtering a signal at a receiver, the signal having at least a desired channel and blockers. A first converter converts a first copy of the signal resulting in a relatively narrow band, high-resolution first signal. A second converter converts a second copy of the signal resulting in a relatively wide band, low-resolution second signal. Once each copy of the signal is converted, the copies are passed to a combiner. At the combiner, the two copies of the signal are analyzed and the desired channel is extracted from the first copy of the signal by removing any inter-modulation product caused by any interference detected in the second copy from the blockers (not detected in the first copy). | 04-16-2009 |
