Secure method and system for computer protection
Attacks by computer viruses, worm programs, and other hostile software (‘malware’), have become very serious problems for computer systems connected to large communication networks such as the Internet. One potential defence against such attacks is to employ diversity—that is, making each copy of the attacked software different. However, existing diversity techniques do not offer sufficient levels of protection. The invention provides an effective diversity solution by applying tamper resistant software (TRS) encoding techniques, to the communications that take place between software components, with corresponding changes to the code handling those communications. These communications may include, for example, data passed between software routines via parameters or mutually accessible variables, light-weight messages, signals and semaphores passed between threads, and messages passed between software processes. Effective TRS encoding techniques include data-flow encoding and mass-data encoding techniques.

Cache directed sequential prefetch
A technique for performing stream detection and prefetching within a cache memory simplifies stream detection and prefetching. A bit in a cache directory or cache entry indicates that a cache line has not been accessed since being prefetched and another bit indicates the direction of a stream associated with the cache line. A next cache line is prefetched when a previously prefetched cache line is accessed, so that the cache always attempts to prefetch one cache line ahead of accesses, in the direction of a detected stream. Stream detection is performed in response to load misses tracked in the load miss queue (LMQ). The LMQ stores an offset indicating a first miss at the offset within a cache line. A next miss to the line sets a direction bit based on the difference between the first and second offsets and causes prefetch of the next line for the stream.

Non-invasive battery recharger for electronic cardiac implants
The present invention refers to a device used to recharge the battery of electronic cardiac implants, like implanted pacemakers and defibrillators. It can be used to recharge the battery after an emergency requirement, such as: defibrillation or in diagnosis and or reprogramming of implants, during which no energy is demanded from the internal battery, seeing that the energy feed becomes guaranteed (accepted) by the proposed device. The invention is composed by three essential components: a generator (A), a transmitter unit (B) and a receptor coil (C). The generator is destined to produce an energy signal with determined amplitude and frequency and that is carried across through a coaxial cable to the transmitter unit (B). The emitted magnetic field is captured by the receptor coil (C) that is implanted inside the human body, generating a voltage with the absence of the Gibbs phenomenon. Furthermore, the battery recharging device guarantees the energetic supply of a communication channel between the exterior for diagnosis and/or implant reprogramming. In this case, there will be no demand of energy from the internal battery.

Coherent optical receiver
A coherent optical receiver of the invention combines local oscillator light having orthogonal polarization components in which the optical frequencies are different to each other, and received signal light, in an optical hybrid circuit, and then photoelectrically converts this in two differential photodetectors. Then this is converted to a digital signal in an AD conversion circuit, and computation processing is executed in a digital computing circuit using the digital signal, to estimate received data.

Two-dimensional photonic crystal resonator
The present invention intends to provide a two-dimensional photonic crystal resonator having a high Q-value. The slab-shaped body 21 is provided with cyclically arranged holes 22. The body 21 is divided into three areas 31-33 with the holes 22 arranged with cycle distances of a1 in area 31 and a2 in areas 32 and 33, which is smaller than a1. A waveguide 23 passing through the three areas is formed by linearly eliminating the holes 22. The waveguide 23 thus formed can propagate rays of light within a wavelength band that depends on the cycle distance of the holes 22. The cycle distance of the holes in the area 31 differs from that of the areas 32 and 33, and the wavelength band of the light propagating through the waveguide accordingly differs. Therefore, a ray of light whose wavelength is within the waveguide transmission wavelength band of the area 31 but outside of the waveguide transmission wavelength band of the other areas 32 and 33 will be confined within the waveguide of the area 31 and resonate therein. Thus, the waveguide in the area 31 functions as a resonator.

Apparatus and system for recognizing environment surrounding vehicle
In conventional systems using an onboard camera disposed rearward of a vehicle for recognizing an object surrounding the vehicle, the object is recognized by the camera disposed rearward of the vehicle. In the image recognized by the camera, a road surface marking taken by the camera appears at a lower end of a screen of the image, which makes it difficult to predict a specific position in the screen from which the road surface marking appears. Further, an angle of depression of the camera is large, and it is a short period of time to acquire the object.
