Abstract: This invention is directed to aqueous-based ethylene-vinyl acetate (EVA) polymer emulsions suited for use in heat seal applications. The EVA polymers of this invention are produced by a relatively low-pressure process, i.e., less than 2000 psig, preferably from about 1000 to about 2000 psig. The aqueous-based EVA based polymer emulsions contain crystalline segments resulting from ethylene linkages and are prepared by emulsion polymerizing ethylene and vinyl acetate, preferably with a carboxylic monomer, in the presence of a stabilizing system containing surfactant or a cellulosic protective colloid in combination with surfactant.

Abstract: A data processing system and method included within an oscilloscope for independently analyzing a signal input into the oscilloscope. The oscilloscope includes a plurality of triggering modes. A plurality of trigger parameters are specified for each of the triggering modes. Thereafter, the oscilloscope automatically analyzes the input signal, independently from any user input, utilizing each of the triggering modes and the trigger parameters specified for each of the triggering modes. The input signal includes a desired waveform and a plurality of undesired waveforms. While the oscilloscope is automatically analyzing the input signal, a determination is made regarding whether the oscilloscope triggered on one of the undesired waveforms. When it is determined that the oscilloscope triggered on one of the undesired waveforms, the undesired waveform upon which the oscilloscope triggered is stored.

Abstract: A method and system for performing direct memory access (DMA) transfers using operating system allocated I/O buffers provides a mechanism for device to device transfers without utilizing global system memory. Memory is allocated on a local bus to which both devices have a requested degree of affinity and transfers are performed to and from this memory. Operating system routines provide for selection of global system memory or local memory based on whether there is local memory available to which both devices have a requested degree of affinity. The memory can be deallocated after each transfer and reallocated for each subsequent transfer.

Abstract: Disclosed is a method and system for protecting electronic files from unauthorized access. The drive on which the file is stored is provided with a hardware identification code, which is unique to the drive and known only by a user to whom access to the files stored on the drive is authorized. An Operating System (OS) extension is created. The OS extension allows a user to provide a security code required to access a requested drive. OS device driver, working in conjunction with the extension of the OS checks the requested drive to determine if an access code is required, and the drive responds with the security code or a default code. The default code indicates that no user-provided access code is required, and the drive is globally accessible to users on the system. Thus, when the default code is returned by the drive, automatic access to the drive is provided.

Abstract: An error injection tool, connected to a bus to be tested in such a manner as not to interfere with normal operation, is employed for error detection and recovery design verification. The error injection tool is connected to the bus to be tested within a data processing system, the system is powered on, and applications simulating normal system loading are run. A desired error is then selected, and the error injection tool is actuated. The error injection tool monitors bus cycles and transactions through selected signals and, upon detecting an appropriate cycle or transaction, overdrives a selected conductor within the bus being tested to inject an error. The selected bus conductor is overdriven (forced) to a logic high or a logic low for a single clock cycle, simulating the intermittent nature of errors likely to occur during normal operation. Bus error signals are then monitored to ascertain whether the error was successfully injected.

Abstract: A method for checking security of data received by a computer system within a network environment is disclosed. In accordance with a preferred embodiment of the present invention, an incoming packet from a client is first decrypted within a receiving communications adapter by utilizing a master decryption key. The decrypted incoming packet is then encrypted by utilizing an encryption key identical to an encryption key employed by the client. A determination is made as to whether or not a packet produced from the encryption is identical to the incoming packet. In response to a determination that a packet produced from the encryption is identical to the incoming packet, the decrypted incoming packet is forwarded to a system memory of the computer system. As such, any incoming packet that does not meet this criterion will be rejected as a security threat.

Abstract: This invention relates to improved vinyl acetate-ethylene emulsions for use in formulating high performance paints without the need for coalescing solvents. These latexes are based on copolymers of vinyl acetate and ethylene optionally containing a comonomer such as an alkyl acrylate or methacrylate. Paints formulated from these latexes, without coalescing solvents, are characterized as having substantially no insolubles, the resin particles in the emulsion are characterized as having a particle size of from 0.2 to 0.35 microns measured as weight average by capillary hydrodynamic fractionation. In other words, the copolymer particles are characterized in that a small percentage, up to about 5% of the total number of particles in the latex, have an average size greater than 0.35 microns, and a small percentage have a size smaller than about 0.2 microns. Further the resin particles are essentially monodisperse.
