Abstract: Systems and techniques are described for robust radar-based gesture-recognition. A radar system detects radar-based gestures on behalf of application subscribers. A state machine transitions between multiple states based on inertial sensor data. A no-gating state enables the radar system to output radar-based gestures to application subscribers. The state machine also includes a soft-gating state that prevents the radar system from outputting the radar-based gestures to the application subscribers. A hard-gating state prevents the radar system from detecting radar-based gestures altogether. The techniques and systems enable the radar system to determine when not to perform gesture-recognition, enabling user equipment to automatically reconfigure the radar system to meet user demand. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for radar-based gesture-recognition.

Abstract: Systems, methods, and software for filtering components, such as hardware components, compatible with computer-modeled structures are presented. A compatible components system provides selection methods that present components compatible with computer-aided design (CAD) models designed in computer modeling software. The system executes methods designed to filter components made available to designers using attribute information of the features and attribute information of the components. Designers may interact with the compatibility methods numerous times, narrowing components through a series or number of filtering steps until a desired compatible component is easily selected. The computer modeling software may include graphical user interfaces for selecting component source locations, filtering types of components presented by the system, and adding components to CAD models.

Abstract: A safety management system includes a processor and memory in which a safety database is maintained. The safety management system receives safety data from one or more portable devices and/or computers, and the system stores this safety data in the database. When a safety incident occurs, such as an accident, the type of incident is recorded and additional information about the incident is recorded in the database. This information then is used to generate a model of the rate of safety incidents. This model is then used to forecast future safety incidence rates for planning and budgeting purposes.

Abstract: An automatic polarization controller is described that includes an optical input that receives a polarization multiplexed optical pulse train that comprises a first and a second polarized optical pulse train. A dither modulation signal is superimposed on at least one of the first and the second polarized optical pulse trains. A polarization transformer transforms an input polarization state of the polarization multiplexed optical pulse train to an output polarization state in response to a control signal that is applied to a control input of the polarization transformer. A polarization selective element receives the transformed polarization multiplexed optical pulse train and passes a polarized optical pulse train including the dither modulation signal. A detector receives the polarized optical pulse train including the superimposed dither modulation signal and generates a signal that is proportional to the amplitude of the dither modulation signal.

Abstract: An apparatus and method for dynamically optimizing performance in a communication channel are described. The communication channel can be part of a high-speed digital network such as the Internet and can be a dense wavelength-division multiplexed (DWDM) optical communication channel. The DWDM signal includes forward error correction (FEC) information which is added to the DWDM signal and is used within the DWDM optical layer to monitor transfer errors in the data. Error correction statistics generated as a result of analysis of the FEC information in the data in accordance with the invention are used in generating an adjustment to and/or optimizing performance of the system. An adjust signal used in generating and making the adjustment is generated using FEC error correction statistics. In one embodiment, the adjust signal is a feedback signal transferred back to the transmission end of the channel.

Abstract: An apparatus and method for monitoring performance of a communication channel or link are described. Errors in the transfer of data are detected and corrected using forward error correction (FEC). The FEC statistics are monitored to determine conditions related to performance of the system. For example, the number of errors corrected by the FEC can be monitored over predetermined periods of time. Using this approach, certain fading errors which tend to correct themselves over time without intervention can be identified, and costly, time consuming troubleshooting and repair efforts can be avoided. By monitoring the types of errors being corrected, i.e., one-bits or zero-bits, certain particular conditions, such as coherent crosstalk, can be identified. Also, monitoring the FEC statistics, particularly numbers of errors corrected, permits identification of system performance degradation at extremely low error rates, such that a Q-measurement for the system is generated.

Abstract: An exemplary system and method for differential group delay compensation are provided that include a method for differential group delay compensation of an optical signal that increases overall bandwidth and reduces the bit-error-rate of a fiber optic transmission system. The method includes generating a translated polarization signal by translating the wavelength of either or both of a leading polarization signal and a trailing polarization signal of an optical signal. The wavelength(s) is translated by an amount that is related to the delay between the leading polarization signal and the trailing polarization signal. The translated polarization signal may then be introduced, along with the other polarization signal, to an optical fiber, such as a dispersion compensating fiber with high chromatic dispersion, that has the optical property of a group delay that varies with wavelength. This results in the generation of a differential group delay compensated optical signal.
