Abstract: The present invention provides a projectile for use in a simulated fan-blade-off ballistic test. The projectile has an ellipsoid body having a blind axial bore extending from a first axial end. The blind axial bore is for housing a weight adjustment body which can be used to modify the weight and/or centre of gravity of the projectile. A sealing plug may seal the weight adjustment body within the axial bore and an insert may be provided to fix the position of the weight adjustment body and/or to control the sliding of the weight adjustment body within the axial bore.

Abstract: A portable data transport device that provides security to data stored therein, and is configured to communicate data with a host computer for securing and transporting data. The portable data transport device includes a first processor and a biometric identification system. Upon successful biometric identification of an enrolled user, the first processor permits mounting of the data transport device to a host computer. However, prior to the commencement of read/write operations, cross-checking of stored identification codes of components of the portable data transport device occurs, including the use of a hash function. If any identifier does not match, no read/write data operations are permitted. The portable data transport device includes a file security program that includes a DLL encryption/decryption program having a self-check feature. Upon self check, if any changes were made to the encryption/decryption program, no read/write operations are permitted.

Abstract: A mobile video surveillance apparatus comprises a single equipment chassis and enclosure within a motor vehicle, and plural video cameras mounted on the motor vehicle; the chassis incorporating a power converter interconnected for operation from a battery source, an embedded computer including a cellular wireless network device, a video capture circuit interconnected with multiple video cameras for receiving transmitting and recording video signals therefrom, storage capability, a signal amplifier whereby the video signals are able to be transmitted via the public cellular network via Internet to selected remote locations and remote viewers are able to select each of the plural video camera feeds for viewing via the Internet.

Abstract: A generally planar light-diffusing sheet or screen has, in one embodiment of the invention, off-axis characteristics such that the maximum aligned gain, is at significant angle with respect to the normal to the plane of the sheet or screen. In another embodiment, the maximum gain is at an angle of 0° to 20° to the normal to the plane of the sheet or screen. The screen may be a photopolymer diffuser in which the light diffusive characteristics are due at least partly to refractive index variations within the material of the diffuser, and wherein said refractive index variations define graded refractive index lenses or analogous optical features having optical axes which are inclined with respect to the normal to the plane of such sheet or screen.
