A 5D printer, which additively manufactures an object, includes an extruder that can move linearly along three orthogonal axes and rotationally around at least one of the axes with respect to the object while depositing a material. A gantry is movable along X, Y and Z axes, and a trunnion table movable about A and B axes is mounted on the gantry. A platen is mounted on the trunnion table, and the extruder deposits the material on the platen while moving the gantry and trunnion table. A model of the object is analyzed to produce a stress tensor for the object, and the depositing is according to the stress tensor.

A method delivers information to satisfy current needs of a driver of a vehicle, by first acquiring data related to a current state of the vehicle. The current state and a predictive model are passed to a predictive procedure to determine choice probabilities for nodes in a choice tree (CT). Based on the choice probabilities, information related to the current needs to the driver are selected from a database storing commercial and non-commercial information. Then, the information is delivered to the driver, wherein the delivering is autonomous of the driver.

A blanking scheme for mitigating impulsive noise in wireless networks is based on the signal-to-noise ratio (SNR) of symbols. To fully gain the benefits of the SNR-based blanking scheme, two methods are developed, namely a multi-level thresholding scheme in the time-, spatial- and frequency-domains, and a weighted-input error-correction decoding. The symbols are conditioned as a function of the estimated SNR in time-, frequency-, or spatial-domains or combinations therefore, and the conditioning is applied to an amplitude, phase, or energy level, or combinations thereof.

A set of symbols is encoded using a continuous mapping function to produce corresponding encoded functions, wherein the mapping function is continuous and values of the encoded functions are real and vary continuously. The encoded functions are summed in a spatial domain to generate a summed function, which is biased so that values of a biased function are all positive and real. Then, a physical property of the object is altered according the biased function to arrange a mark on the object.

An interferometer produces a first optical signal and a second optical signal interfering with each other. The optical signals are converted digital signals form addresses. A memory stores data values corresponding to the first and second optical signals, and in which the addresses are used to directly read the data values stored at the addresses. The data values stored in the memory can be dynamically adapting while converting the first and second optical signals and reading the data values.

Memory-based high-speed interferometer

A method tracks an object in a sequence of frames of a video. The method is provided with a set of tracking modules. Frames of a video are buffered in a memory buffer. First, an object is tracked in the buffered frames forward in time using a selected one of the plurality of tracking module. Second, the object is tracked in the buffered frames backward in time using the selected tracking module. Then, a tracking error is determined from the first tracking and the second tracking. If the tracking error is less than a predetermined threshold, then additional frames are buffered in the memory buffer and the first tracking, the second tracking and the determining steps are repeated. Otherwise, if the error is greater than the predetermined threshold, then a different tracking module is selected and the first tracking, the second tracking and the determining steps are repeated.

An apparatus measures a fluid level in a container. A light source emits a light beam. A light sensor can sense the light beam. An optical conduit is arranged in a container for holding fluid. The optical conduit is arranged between the light source and the light sensor along a path of the light beam, such that at least one part of the light beam passes through the optical conduit, and at least an other part of the light beam passes through the fluid when the container holds the fluid. The sensor senses the light beam when a level of the fluid coincides with the one part of the light beam passing through the optical conduit, and the sensor does not sense the light beam when the level of the fluid coincides with the other part of the light beam passing through the fluid due to internal reflection at the fluid level.

A method compares a background image to input images to determine a similarity scores &#x3bb; for each input image. Then, the background image is updated only if the similarity score for a particular image is less than a predetermined threshold. Presumably, any pixel whose color does not change is part of a static background, and any pixel that does change is part of a moving object. The similarity score controls when input images are scored and the manner the background image is updated.

Adaptive background image updating

An interactive display system includes a sensor for sensing a relationship between a mobile coordinate frame fixed to a moving projector, and a stable coordinate frame fixed to a stationary display surface in the real world. An output image to be projected on the display surface is partitioned into a black image portion having a fixed relationship to the mobile coordinate frame, a stable image portion within the block image portion having a fixed relationship to the stable coordinate frame, and a mobile image portion within the stable image portion having a fixed relationship to the mobile coordinate frame. The mobile portion can be used as a pointer within the stable portion in a mouse-cursor like manner.
