Document page segmentation in optical character recognition
Page segmentation in an optical character recognition process is performed to detect textual objects and/or image objects. Textual objects in an input gray scale image are detected by selecting candidates for native lines which are sets of horizontally neighboring connected components (i.e., subsets of image pixels where each pixel from the set is connected with all remaining pixels from the set) having similar vertical statistics defined by values of baseline (the line upon which most text characters “sit”) and mean line (the line under which most of the characters “hang”). Binary classification is performed on the native line candidates to classify them as textual or non-textual through examination of any embedded regularity. Image objects are indirectly detected by detecting the image's background using the detected text to define the background. Once the background is detected, what remains (i.e., the non-background) is an image object. |

High sensitivity GPS receiver
A high sensitivity GPS receiver includes an acquisition engine and a tracking engine. The acquisition engine processes GPS satellite data at data rate that is substantially equal to twice the coarse acquisition (CA) code chip rate. This data rate advantageously enables the acquisition engine to process GPS satellite data with relatively less hardware area than traditional GPS acquisition approaches. In one embodiment, the high efficiency acquisition engine may be over-clocked, thereby allowing different phases of a CA code to be correlated quickly. The tracking engine can advantageously process GPS satellite data at a data rate that does not have an integer relationship to the CA code chip rate. |

Viterbi equalization with detection of the nearest constellation points for stage reduction
The device is used for decoding convolution-encoded reception symbols. In this context, transmission data are modulated with a modulation scheme to form symbols, which are encoded with a transmission filter to form convolution-encoded transmission symbols. A convolution-encoded transmission symbol contains components of several symbols arranged in time succession. These transmission symbols are transmitted via a transmission channel and received as reception symbols. The Viterbi decoder decodes the reception symbols by use of a modified Viterbi algorithm. Before running through the Viterbi decoder, the reception symbols are processed by a state-reduction device, which determines additional items of information relating to possible consequential states of the decoding independently of the decoding through the Viterbi decoder in every state of the decoding. The state-reduction device uses the additional items of information to restrict the decoding through the Viterbi decoder to given consequential states. |

Method and apparatus for low power simultaneous frequency, automatic gain control and timing acquisition in radio receivers
A method and apparatus are provided for low power simultaneous frequency, automatic gain control and timing acquisition in a low power radio receiver. A baseband signal received is split into a limited signal having limited data and a non-limited signal.

The non-limited signal is fed through an automatic gain control path where automatic gain control is performed on the non-limited signal simultaneously with the coarse frequency and timing estimations and packet synchronization detection performed by the PSK correlator. By operating the PSK correlator on limited data from the received baseband signal and through a separate path from the automatic gain control, substantial power savings are achieved without degrading performance since the preamble time is significantly reduced. |

System and method for improved spur reduction in direct RF receiver architectures
Improved spur reduction architectures that improve linearity in direct radio frequency (RF) receiver architectures. Non-uniform sampling in the form of sampling clock phase (or frequency) modulation is used to induce phase (or frequency) modulation on signals that are being received from a given Nyquist zone. At the output of the ADC (analog-to-digital converter), the signals are de-modulated to remove the induced modulation based on the Nyquist zone that is being received. The de-modulation process results in non-desired spurious artifacts (interfering leakage signals and ADC spurs) being spread in the frequency domain. Strong spurious artifacts may be removed after measuring the induced modulation and de-modulating. For the case of weak spurious artifacts, the de-modulation for the desired Nyquist zone spread these signals in the frequency domain. Induced modulation on signals may also provide a dithering effect on the ADC. |

Network traffic accelerator
In a packet communication system with large bandwidth delay product (BDP) and employing Transmission Control Protocol (TCP), the reported advertised window size as advertised by a receiver is employed only as an indication of window size and not as a throughput limit so that more data is sent than the amount specified by the advertised window size. Since the receiver can process all incoming TCP packets, the receiving buffer is consistently near empty. Since the TCP's advertised window size is not accepted as the absolute amount of buffer space available at the receiver, the sender is not constrained by the absolute value of the receiver's advertised window size and instead can transmit more data than the absolute value of the advertised window, enabling the system to increase the actual window size without modifying the link ends. This improved large-BDP-capable protocol is denoted TCP-SC. |

Active-avoidance-based routing in a wireless ad hoc network
Conventional multi-hop routing of ad hoc wireless networks involves considerations such as costs, connection quality, distances, and numbers of hops. A conventional wireless routing algorithm may fail when a destructive event takes place and is rapidly expanding in area, as the route discoveries may perpetually lag behind the rate of expansion of the destructive area. As typically embodied, the present invention's wireless routing algorithm detects a destructive event early, assumes rapid expansion of the destruction area, establishes “subnets” of nodes, and predetermines one or more routes that circumvent the rapidly expanding destruction area by exiting from and returning to the subnet in which the destructive event originates. Typical inventive practice avails itself of the architectural character of the physical setting for the wireless network, for instance by establishing subnets corresponding to compartments formed by wall-like structures (e.g., shipboard bulkheads), which represent natural barriers to expansion of a destruction area. |

The electric circuit has an element breakdown prevention circuit 10 having a first circuit terminal connected to an output terminal of the constant-current power supply 1 through the functional element 2, and a second circuit terminal connected to the reference potential terminal of the constant-current power supply 1 through the functional element 2. The element breakdown prevention circuit 10 increases an impedance between the circuit terminals to a disconnected state impedance in response to a transition from a connected state, in which the functional element 2 is mounted, to a disconnected state, in which the functional element 2 is removed. The element breakdown prevention circuit 10 decreases the impedance between the circuit terminals to a connected-state impedance in response to a connection state transition. |

Overvoltage protection circuit and electronic device comprising the same
An overvoltage protection circuit prevents a voltage higher than an allowable voltage value from being supplied to a predetermined to-be-protected circuit. A voltage is applied from outside to an input end 11. A cathode terminal of a zener diode 13 is connected to the input end 11. A first resistance element 14 is connected between an anode terminal of the zener diode 13 and a ground terminal. A voltage detection integrated circuit 15 detects a voltage between both ends of the zener diode 13, and outputs a detection signal that indicates whether or not the detected voltage is higher than the allowable voltage value. When the detection signal indicates that the detected voltage is no higher than the allowable voltage value, a MOSFET 16 supplies the to-be-protected circuit with the voltage applied to the input end 11. When the detection signal indicates that the detected voltage is higher than the allowable voltage value, the MOSFET 16 ceases the supply, to the to-be-protected circuit, of the voltage applied to the input end 11. |

Multiple phase circuit testing closer method
Upon detecting a fault, a circuit testing closer is operable to open contacts to isolate the fault. Next, the circuit testing closer tests the faulted phase to determine whether the fault has cleared. The circuit testing closer may employ one or more dynamic thresholds to determine the existence of a fault. |

Integrated circuit with DC-DC converter and ESD protection
An integrated circuit (10) for use in a DC-DC converter is protected against damage from electrostatic discharge when not in use in the DC-DC converter. The integrated circuit includes a control circuit (11) and a switching transistor (12, 20) coupled between a first and second terminal (10a, b) of the integrated circuit (10). During DC-DC conversion the control circuit controls periodic switching of the switching transistor. The integrated circuit (10) furthermore comprises an electrostatic discharge (ESD) protection circuit, with a high pass filter circuit (160, 162) with inputs between terminals (10a, b) of the integrated circuit (10) and an output coupled to a detector transistor (164). The detector transistor (164) charges a chargeable circuit (17). From a node between the detector transistor (164) and the chargeable circuit (17) the switching transistor (12, 20) is made conductive when the detector transistor (164) becomes conductive. By using a high pass filter circuit (160, 162) the ESD protection circuit is made to work outside normal use. When the DC-DC converter contains multiple switching transistors all are preferably made conductive upon detection of ESD. |
