Abstract: In a system for establishing connectivity in a HF ALE cellular network, stations are organized to sound each channel, synchronized to every other station in the network. All stations make identical sounding transmissions using a single address, synchronized such that the differential timing within the coverage area remains within the mobile radios' delay spread capability. Synchronized soundings allow the mobile radio to consistently connect to the best available channel. The stations may be synchronized via a central control function. Alternatively, the stations may perform soundings based on a predetermined schedule. Where the propagation time to the mobile radio is known, or determinable within some threshold, the stations may apply a delay to the sounding transmissions to ensure that the sounding transmissions from each of the stations reaches the mobile radio at the same time within some acceptable margin.

Abstract: A radio system receives a forward error correction encoded signal for retransmission. The system performs symbol detection to produce soft decisions for the encoded bits. The soft decisions are used in the generation of the rebroadcast signal prior to any deinterleaver or error correction decoding, and the rebroadcast signal is transmitted. The system may determine if soft decisions exceed some threshold of confidence; if so, the detected bits may be used in the generation of the rebroadcast signal instead of the soft decision bit values. The system may enter a low latency mode based on some criteria such as a type of application, or a minimum necessary latency.

Abstract: A system and method for increasing the efficiency of an avalanche relay scheme is disclosed. The system and method include a plurality of networked nodes communicating in a slot and subslot scheme, with transmissions of a first signal from a first subslot relayed in subsequent subslots. The method and system include transmitting an initial transmission that includes the first signal, and then continuing to transmit at least one of a retransmitted portion of the first signal, or a transmission of an algorithmically related signal based on the first signal. The receiving node combines the first signal with the retransmitted portion of the first signal or the algorithmically related signal to determine if the initial transmission is valid. Upon a determination that the initial transmission is valid, the relay node retransmits the initial transmission in a future subslot.

Abstract: A notification system for sending a message to a receiving station via one or more repeater stations is disclosed. The repeater stations receive the message over a channel from a sending station. The distributed network immediately begins transmitting a signal coordinated with the message received where the message appears as multipath to a receiver or set of receivers. This asynchronous relay transmission start minimizes the time to incorporate additional transmitters and allows strong links to be discovered and employed without waiting for synchronized subslot transmission starts. In other operations, an asynchronous scanning operation may be included to provide a sufficient transmission time to account for network worst case net cycle times.

Abstract: A system and method for performing real-time quality inspection of objects is disclosed. The system and method include a transport to move objects being inspected, allowing the inspection to be performed in-line. At least one optical acquisition unit is provided that captured optical images of the objects being inspected. The captured optical images are matched to CAD models of objects, and the matched CAD model is extracted. A laser with an illumination light beam has a wavelength in the violet or ultraviolet range then conducts scans of the objects, which are formed into three-dimensional point clouds. The point clouds are compared to the extracted CAD models for each object, where CTF are compared to user input or CAD model information and the object is determined to be acceptable or defective based on the extent of deviation between the point cloud and the CAD model.

Abstract: A system for receiving multipath signals is disclosed. The system includes an equalizer that includes an input for a received data signal, wherein the received data comprises a first multipath component and a second multipath component. The equalizer further includes a channel impulse response estimator coupled to the input configured to determine one or more channel impulse response (CIR) estimates for the first multipath component and the second multipath component. The equalizer further includes a statistical estimation module coupled to the channel impulse response estimator configured to estimate a state of the first multipath component and the second multipath component based on the one or more channel impulse response estimates. The equalizer further includes a detector coupled to the statistical estimation module configured to detect data from the received data signal based on an estimated future state of the first multipath component and the second multipath component.

The first tab is fixed directly onto the skin and the second tab is fixed directly onto the skin. The frame comprises a cut-out, a first foot, and a second foot. The second foot is spaced apart from the first foot by the cut-out. The first foot is fixed directly onto the first tab of the stringer, such that the first tab of the stringer is immediately interposed between the first foot of the frame and the skin. The second foot is fixed directly onto the skin, such that no portion of the frame is fixed directly onto the second tab of the stringer.

Abstract: A system and method for including multiple data rate sub-blocks within a single data block includes dividing data blocks based on a priority or intended set of recipients. The sub-blocks are modulated at increasing data rates and the modulated sub-blocks are appended together and bounded by the known symbol blocks during transmission. The sub-blocks are organized in order of increasing data rate. During decoding, detected symbols of a first, low data rate sub-block are included in the detection process of higher data rate sub-blocks in place of additional symbols that would otherwise be needed for higher data rate transmissions. Alternatively, the sub-blocks may be organized with low data rate sub-block at the periphery and higher data rate sub-blocks in the interior such that the data block may be decoded from both ends.
