Abstract: A vehicle system includes a first sensor and a second sensor, each having, respectively, different first and second modalities. A controller includes a processor configured to: receive a first sensor input from the first sensor and a second sensor input from the second sensor; detect, synchronously, first and second observations from, respectively, the first and second sensor inputs; project the detected first and second observations onto a graph network; associate the first and second observations with a target on the graph network, the target having a trajectory on the graph network; select either the first or the second observation as a best observation based on characteristics of the first and second sensors; and estimate a current position of the target by performing a prediction based on the best observation and a current timestamp.

Abstract: A computing platform for multiple intelligent transportation systems in an automotive vehicle having a plurality of sensors which generate output signals representative of various vehicle operating parameters. The platform includes a vehicle data center which receives input signals from the vehicle sensors and the vehicle data center is configured to transform these input signals into output signals having a predetermined format for each of the vehicle operating parameters. A central processing unit receives the output signal from the vehicle data and is programmed to process the vehicle data center output signals for each of the intelligent transportation systems and generate the appropriate output signals as a result of such processing.

Abstract: Method and system for imaging an object in three-dimensions, binning data of the imaged object into three dimensional bins, determining a density value p of the data in each bin, and creating receptive fields of three dimensional feature maps, including processing elements O, each processing element O of a same feature map having a same adjustable parameter, weight Wc1. The density values p are processed with the processing elements O to determine an output value o for at least each three dimensional location of the imaging of the object having a density value p above a predetermined threshold value. An object is classified by processing the output values o with a committee of classifiers, and the classification of the object is communicated.

Abstract: Method and apparatus for scheduling time division multiple access (TDMA) communications among a plurality of peer nodes arranged to form a wireless ad hoc mobile network. The peer nodes communicate with each other using directional antennas and a TDMA process. The method includes a scheduling process for scheduling at least one transmit time slot during which a first one of the plurality of peer nodes transmits wireless data to a second one of the plurality of peer nodes.

Abstract: A glass block, and method for making a glass block, having one or more formed slots on one or more edge faces of the block. The slots are formed during the molten state of the glass formation to maintain the mechanical integrity of the glass structure in architectural applications. The glass block may have an insert placed inside by way of the formed slot, the insert having performance and/or decorative properties.

Abstract: A hybrid focal plane array (FPA) structure including a Balanced Composite Structure (BCS) in which several layers of materials having differing thermal expansion coefficients stabilize the FPA during cryogenic cooling. An optical substrate with a layer of an optically sensitive material detects impinging radiation. The optically sensitive material is coupled to a multiplexer (MUX) substrate via interconnection bumps. The MUX is bonded to a layer of a material having a high TEC. A rigid core layer is sandwiched between the MUX and a balancing layer formed of a material having similar mechanical and geometrical characteristics to the MUX substrate. The three-layer BCS consisting of the MUX, the rigid core layer and the balancing layer is designed to have an effective TEC matching that of the optical substrate. The bumps and the optically sensitive material are thus protected from undesirable stresses generated during thermal excursions, thereby resulting in substantially improved FPA reliability.

Abstract: A mechanism for correcting for time-varying errors that affect the pointing accuracy of a shipboard mounted antenna employs a Kalman filter for realizing an optimal correction estimator through which inputs to the antenna aiming control hardware are adjusted. A series of coordinate system transformations, corrected by the Kalman filter error estimator, are carried out to provide a command input to an antenna pointing servo system. The servo control system produces a servo error signal representative of a deviation in the actual direction of the antenna pointing mechanism from the command input to the servo loop as defined by the corrected aiming signal. The actual direction in which the servo control system points the antenna is compared with a reference (the actual direction to the satellite). As a result of this comparison, a pointing deviation signal representative of any offset from the intended pointing direction is generated.

Abstract: Apparatus and method for determination of residual stress in crystalline substances. An X-ray source is focused at two different, preselected angles with respect to a surface of a substance, and X-ray diffraction peaks are located with a single position-sensitive X-ray detector. The apparatus has positioning probes affixed to a base for maintaining the base in fixed relationship with the substance, and an arcuate glide channel formed in the base for controlled angular shifting of the X-ray source and detector. Residual stresses are determined more quickly than with prior art methods and apparatus having comparable precision because only a single detector is used, and because the detector locates diffraction peaks without time-consuming diffractometer shifting.
