Abstract: A method of exchanging data among software components includes acquisition by each software component of all the data that is to be provided by another software component, from a predetermined software component. Each software component delivers all data that is to be provided by it to another software component, to the predetermined software component. Providing and acquiring of all data is performed according to a predetermined standard, according to which the data comprises values and attributes. The respective data values are assigned to attributes, and semantically identical data values are assigned to the same attribute and are made distinguishable from each other by respective hierarchical information. A software component that delivers data to or acquires data from the predetermined software component, receives the respective hierarchical information from another software component. Acquiring and providing data by a software component includes transferring the respective hierarchical information.
Abstract: A container security device includes a housing, electronic circuitry, and cabling. The electronic circuitry is disposed within the housing, and includes first and second microprocessor functions and an interface for accepting and providing data. The cabling is removably coupled to the housing, provides the only communicative coupling between the first microprocessor function and the second microprocessor function, and is adapted to be attached to a container latch so as to break the communicative coupling if the latch is opened. The housing includes a port for the electronic circuitry interface. A method of providing container security includes closing a container using a latch device and removably coupling the cabling to the housing so that the communicative coupling is broken if the latch is opened., providing the only communicative coupling between the first microprocessor function and the second microprocessor function.

Abstract: A method of determining that protected software is running in a virtualized environment includes obtaining a set of baseline measurements of system call timings in native operating system environments. Statistical thresholds are established based on the baseline measurements such that there is a predetermined probability that protected software running in a native environment will experience system call durations that exceed the thresholds. The protected software is analyzed and instructions are incorporated within the software such that particular system calls, demonstrated to be differentiating using the set of baseline measurements and the threshold analysis, are executed during the normal running of the protected software. The incorporated instructions are used to estimate the parameter values that are to be compared with the established statistical thresholds.

Abstract: An electronic signature device includes a processor, a memory, a user input device including a first biometric input device, and a device interface, all communicatively connected by at least one bus. A method of personalizing the electronic signature device to a user includes receiving a digitized biometric signature of the user via the first biometric input device. A cryptographic key is generated. A biometric electronic template is generated based on the digitized biometric signature. The cryptographic key and the biometric electronic template are stored in the memory.
Abstract: A positive-displacement reciprocating compressor, comprising a plunger slidingly coupled inside a cylinder, in which a compression chamber is located, and operatively connected to a motor which put it in motion inside the cylinder. The motor has a rotation shaft coupled with an eccentric cam mechanically connected to the plunger and able to impose longitudinal displacements to the plunger according to an orthogonal direction with respect to the rotation axis of the shaft.
Abstract: A process of conditioning a fluid includes passing the fluid through a magnetic field. A fluid conditioning system includes a conduit through which fluid passes, and a magnet assembly including at least one magnet disposed such that the produced magnetic field penetrates the conduit. The conduit is formed from a material that allows the magnetic field to have a magnetic effect on molecules of the fluid as it passes through the conduit. The conduit has a cross-sectional area designed to maintain a flow rate of the fluid through the conditioning volume within a pre-determined range. The magnetic field produced by the magnet has a field strength within the conduit, and the predetermined range is predetermined as a factor in combination with the field strength to precipitate an ion from the fluid in the conditioning volume.

Abstract: Embodiments of the present invention provide for a photoacoustic imaging probe for use in a photoacoustic imaging system, said probe comprising a cohesive composite acoustic lens incorporating aspheric geometry and exhibiting low or practically no measurable dispersion of acoustic waves constructed of at least one material with a low acoustic impedance and attenuation and a relatively low acoustic velocity and at least one other material with a low acoustic impedance and attenuation and a relatively high acoustic velocity is immersed in preferably a low acoustic velocity and low acoustic impedance fluid. The lens may be designed as a single cohesive composite telecentric lens, an acoustic zoom lens, or a catadioptric lens. The lens focuses acoustic waves on an acoustic imager which detects the image. The lens may be considered to be essentially monochromatic.
