Abstract: A low complexity RACH preamble detector is described herein. The RACH preamble detection algorithm uses the peak detection of the time domain correlation function through frequency domain processing. The frequency domain processing considers the reference signals generated directly from frequency domain CAZAC sequence or time domain CAZAC sequence with DFT conversion. A low-complexity poly-phase LPF along with down sampling is implemented before the FFT to reduce the required length of the long FFT operation N-folded.

Abstract: A computer implemented electronic out-of-office message analysis system and method are disclosed. The method includes, for each of a plurality of users, receiving a user-generated electronic out-of-office message in a natural language in which a time window of absence and at least one alternate named contact are expressed and, based on the out-of-office message, generating a structured representation of the out-of-office message which links the alternate contact to a normalized representation of the time window.

If a conflict is detected, the current user can be notified.

Abstract: The present application is a method and system of interpreting an image by finding a configuration of multiple variables which optimizes an objective function with a factorizable upper bound, by applying an iterative algorithm that relies on efficient dynamic ordering of candidate configurations, in a priority queue, in a descending order of an upper bound score. As an example, consider a constellation model for an object. It specifies the appearance models for individual parts of objects, as well as spatial relations among these parts. These are combined into a single function whose value represents the likeness of the object in an image. To find the configuration in which the object is present in the image, we maximize this function over all candidate configurations. The purpose of the iterative algorithm mentioned above is to find such optimal configurations efficiently.

Abstract: Systems and methods are described that facilitate generating a ready-to-print binary dual-plane HLC image for output to an HLC device. A print-ready highlight color (HLC) image can be generated without digital front end (DFE) processing. For example, according to one or more aspects, a color scanner can be employed to produce a two-plane binary TIFF image. One plane contains black (e.g., achromatic) content, while the other contains highlight color content. Black pixels are identified and/or determined using neutral pixel and neutral window detection. Background pixels are mapped to white for both planes. Pixels that are non-neutral and non-background are designated as color pixels. After separation into a neutral plane and an HLC plane, the planes are processed into binary data for printing.
