An inductive write element is disclosed for use in a magnetic data recording system. The write element provides increased data rate and data density capabilities through improved magnetic flux flow through the element. The write element includes a magnetic yoke constructed of first and second magnetic poles. The first pole includes a pedestal constructed of a high magnetic moment (high Bsat) material, which is preferably FeRhN nanocrystalline films with lamination layers of CoZrCr. The second pole includes a thin inner layer of high Bsat material (also preferably FeRhN nanocrystalline films with lamination layers of CoZrCr), the remainder being constructed of a magnetic material capable of being electroplated, such as a Ni—Fe alloy. An electrically conductive coil passes through the yoke between the first and second poles to induce a magnetic flux in the yoke when an electrical current is caused to flow through the coil. Magnetic flux in the yoke produces a fringing field at a write gap whereby a signal can be imparted onto a magnetic medium passing thereby.

Described herein are the materials, mechanisms and procedures for optimizing various performance parameters of HPDLC optical devices in order to meet differing performance requirements. These optimization tailoring techniques include control and independent optimization of switchable HPDLC optical devices to meet the demanding requirements of anticipated applications for, inter alia, the telecommunications and display industries. These techniques include optimization of diffraction efficiency, i.e., index modulation, polarization dependence control, haze, cosmetic quality, control of response and relaxation time, voltage driving for on and off switching, and material uniformity. This control and independent optimization tailors properties of switchable HPDLC optical devices according to the specific requirements of the application of the switchable HPDLC optical device. The invention disclosed herein retains the desirable attributes of the multi-functional acrylate system for forming HPDLC optical devices, but adds new materials to the acrylate system and / or new process control to the recording to optimize performance parameters as may be needed for specific applications. This results in high optical quality switchable holograms with good diffraction efficiency and low, stable switching voltage.

A system automatically generates OLAP metadata objects for a multidimensional analysis program such as OLAP from SQL statements without involving the database administrator, and eliminates the need for database administrators to manually perform this analysis and design. The system deconstructs a set of SQL statements into tables and aggregates metrics for measures and joins. It recognizes that the relational database structure contains both dimension tables and fact tables. Over many SQL statements, fact tables will have a large measure metric while dimension tables will have a low measure metric. Tables are linked based on large join metrics; small join metrics are ignored. The present system builds the OLAP cube model from the fact tables, dimension tables, and joins. The analysis of the SQL statements allows the system to map the hierarchies within the dimension table, and provides the system with information about attribute relationships and cubes.

A mixing assembly includes a rod extending into the mixing chamber and one or more mixing elements, e.g., a perforated disc or rotating blades, attached proximate a distal end of the rod, the mixing element(s) of a type such that movement of the rod relative to the housing causes the mixing element(s) to mix bone cement located in the mixing chamber. A dispensing piston has an outer periphery sized to seal the proximal opening of the mixing chamber, while allowing the piston to be moved in a distal direction through the chamber, the piston having an opening through which the rod extends, the rod having a stop fixable at a selected location along the rod for engaging and moving the piston distally through at least a portion of the mixing chamber.

A Homogenous Charge Compression Ignition (HCCI) engine is used in conjunction with a hybrid powertrain. Power production from the HCCI engine in operation may be decoupled from, or assisted in, responding to driver power demand. In this manner, the HCCI engine: (i) is relieved from the need to quickly adapt to changes in driver power demand, and / or (ii) is allowed to more slowly transition between power levels reflective of the vehicle power demands, with a secondary power source providing the more immediate power response to driver demands. In addition, driver power demand greater than what can be provided by the HCCI engine may preferably be met through the addition of power from the powertrain's reversible secondary power source (e.g. one or more reversible electric motor / generator(s) or reversible hydraulic pump / motor(s)), thereby avoiding the need for full load operation by the HCCI engine. In this manner, driver power demand may be met by the vehicle with commercially acceptable responsiveness, while simultaneously enabling the use of a highly efficient low emission HCCI engine.

A system that blends a hybrid radio signal may provide reduced audio content skipping and may determine an audio correlation between analog and digital signal components in the hybrid radio signal before blending from the analog signal component to the digital signal component. The system may reduce volume level transitions during blending by adjustment of blend and cross-fade variables, as well as setting a hysteresis mode to prevent undesirable sequential jumping from digital mode back to analog mode. The system also may compensate for digital AM frequency quality issues by adjustment of a filter bandwidth when the receiver blends an AM signal from analog to digital mode.

A low velocity air burst munition and launcher system allows the user to program the munition to detonate in the air at a specified range from the muzzle. The system further allows the munition to detonate upon impact or self-destruct if the target is missed. The system allows the user to program and reset the munition multiple times, and allows the user to perform this operation at night in cold weather conditions. The system requires the user to manually input the range into a fuze programming device prior to projectile launch. The fuze programming device is capable of direct interface with electronic range determining devices. The system employs electrical contacts in the chamber of the munition launcher barrel and on the projectile body to complete the circuit used for programming. Furthermore, this system is capable of integrating a magnetic induction method of programming.

The application is modular so as to be extensible to include other activities and functionalities. In an embodiment, the group interaction application utilizes a peer-to-peer network environment to facilitate network communications between group members.

Systems and methods for image modification to increase contrast between text and non-text pixels within the image. In one embodiment, an original document image is scaled to a predetermined size for processing by a convolutional neural network. The convolutional neural network identifies a probability that each pixel in the scaled is text and generates a heat map of these probabilities. The heat map is then scaled back to the size of the original document image, and the probabilities in the heat map are used to adjust the intensities of the text and non-text pixels. For positive text, intensities of text pixels are reduced and intensities of non-text pixels are increased in order to increase the contrast of the text against the background of the image. Optical character recognition may then be performed on the contrast-adjusted image.
