Abstract: A protective apparatus for a distribution line conductor includes an elongate tube configured to be installed on the conductor and a plurality of annular members concentrically positioned on the tube and configured to rotate independently of each other. The tube has a longitudinal axis and defines a longitudinally extending chamber configured to receive the conductor. The tube has opposite first and second ends and a longitudinally extending opening from the first end to the second end that facilitates installation of the elongate tube on the conductor. Each annular member includes an outer surface and a plurality of circumferentially-spaced apart members extending outwardly from the outer surface. Each annular member includes a longitudinally extending slot that is configured to align with the longitudinally extending opening of the tube to facilitate installation of the elongate tube and the plurality of annular members as an assembly on the conductor.

Abstract: A method for operating a focal plane array in a Time Delay Integration (TDI) mode, the method including: shifting a number of rows during TDI integration, wherein the number of rows shifted is less than a total number of rows of the focal plane array; and reading out a number of rows equal to the total number of rows of the focal plane array minus the number of rows shifted, leaving behind the partially-integrated rows.

Abstract: A method for generating data indicating a degree of anatomical connectivity for each of a plurality of image elements, each image element representing a part of a body to be imaged. The method comprises for each of a plurality of image elements, that image element and others of said plurality of image elements; for each of said plurality of image elements, generating data indicating a degree of connectivity of that image element, said degree of connectivity being based upon said plurality of generated data sets.

Abstract: A system and method of authenticating a digital still image captured using a digital image capture device. To process the digital still image for later authentication, a signature data is transmitted from a remote location to the digital image capture device. Upon capturing the digital still image, an image identification is associated with the digital still image. The signature data is then applied to the captured digital still image to produce an authentication signature representative of the captured digital still image. The authentication signature is associated with the image identification and transmitted from the digital still image to the remote location for storage at the remote location. To verify the authenticity of the digital still image, the digital still image is transmitted to the remote location. The signature data for the transmitted digital still image is accessed and applied to the transmitted digital still image to produce a verification signature.

Abstract: A digital camera having a public key encryption system to establish the authenticity of digital images created by the camera, wherein the private key/public key pair is produced within the digital camera using an algorithm which ensures that it is unique, rather than being produced on a separate computer and uploaded to the camera. The private key is stored in a memory within the digital camera, so that it cannot be discovered.

Abstract: The invention provides, in one aspect, a head up display unit for a re-circulating gas self-contained breathing apparatus of the type having at least one sensor for determining the oxygen partial pressure of the re-circulating gas. At least one optical fibre (32) is provided for transmitting a light signal or signals from a respective light emitter, positioned outside the wearer's field of view and electrically connected to the at least one sensor, to a display (26) in the wearer's field of view to provide the wearer with a visual indication of the light emitter signal or signals.

Abstract: A decorative flashing light system designed to float in ponds, pools and swimming pools that is independent of wiring harnesses and external power supplies. The system consists of a buoyant, translucent shell 16 that encloses a light array circuit assembly 20, and a battery(s) 24, which is kept in place by a waterproof reseal-able cap 28. The flash pattern of the light sources as well as the intensity, frequency, duration and duty cycles are all pre-programmed into the electronic circuitry 10. An anchoring tether 30 allows the display to be held in position rather than free-floating if desired.

Abstract: A cover plate for fluid pumps incorporating an O-ring seal 5 secured in a channel 4. The cover includes slots 7 extending to the edge of the cover plate and securing holes to allow easy positioning of the cover onto bolts which remain located in the body of the pump. These and other securing bolts 8 may have large and knurled heads for rapid finger-tightening so as to avoid the need for tools.

Abstract: A pin and sleeve receptacle is mountable in a wall box recessed in a wall opening of a building with wires extending into the box from an in-wall wiring passage. The receptacle has a tubular electrically non-conductive shell closed at one end, the other end being open and a flange with fastener openings at the open end of the shell. A cylindrical inner body has an outer diameter smaller than the first inner diameter, the inner body having female connector sleeves for receiving electrically conductive pins of a mating plug. The inner body is mounted within the shell with an annular gap surrounding the inner body for receiving the shroud of the pin-and-sleeve plug. The opening at one end face the same direction as the open end of the shell to receive the pins of the plug. Apertures in the shell admit wires from the box for connection to the electrically conductive female connectors.

Abstract: The device includes a plurality of pixel control digit storage elements (1) each for association with a particular pixel of the display and functionally organized in the form of a two-dimensional array corresponding to the array of pixels of the display, interconnected with one another and with data and control signal input means (2, 3, 4) such that a pixel control digit, representing a given color or intensity say, entered into one "seed" element (i,j) automatically propagates through the device from one to another element until it reaches elements to which boundary indicative control signals are applied by way of said input means when propagation ceases. The boundary indicative control signals and the "seed" element may be derived from and chosen by an associated computer processor operating according to a conventional shape designing algorithm.
