Abstract: The Self-Zooming Camera uses proximity detectors and/or motion detectors in the camera to detect the position of the camera/recording device relative to the operator's eye or face. At closest viewable distance to the face (approx. 6 inches), the zoom lens operates at it's widest angle or user-specified widest angle setting. At furthest extent from the face (arm's length, approximately 2 feet), the camera zooms to its longest telephoto extent or user-specified longest zoom setting. The Self-Zooming Camera allows simple and creative zoom operation of a camera, video recorder or mobile device with camera without using buttons or zoom/focus pulling—replacing traditional controls with intuitive gesture or camera motion.

Abstract: Detection of a signature in a data packet comprises performing a pre-classification of the packet, using header information and particularly a 5-tuple access control list, into one of a multiplicity of flows and directing the payload of the packet to a respective one of a multiplicity of deterministic finite state machines each of which stores a plurality of signatures as a sequence of states and acts only on the respective flow.

Abstract: A cargo pallet cover having a main panel and a plurality of side panels extending therefrom, the main panel being adapted to overlie a load on a pallet in use and the side panels being adapted to hang down against the sides of the load, each side panel being attached to an adjacent side panel along adjacent edges to define a corner, the pallet cover including a plurality of net attachment devices for attaching a pallet net to the pallet cover.

Abstract: A wavelength control system comprising a wavelength tunable laser, a temperature sensing mechanism and a bias controller responsive to the sensed temperature whereby emission wavelength or the wavelength tunable laser is maintained substantially constant by adjusting the bias applied to the wavelength tunable laser accordingly with temperature.

Abstract: A one piece end plug (120, 124) for use in a three part ceramic arc tube comprises a cylindrical head portion of a diameter suitable for insertion into a cylindrical body portion and a circular leg portion formed on the head portion so as to be coaxial therewith and tapering inwardly from the head portion outwards, the whole having a through aperture for receipt of electrodes and being formed of single ceramic pressing.

Abstract: A filament array for an incandescent lamp comprises a plurality of helically-coiled filament sections (4-11) which are arranged in one or more parallel planes. At least some (6, 7, 8 and 9) of the filament sections have gap-wound portions (22, 23, 24 and 25), the gap-wound portions being arranged to provide an area (26) in the plane or planes of the array through which light can pass.

Abstract: A filament array for an incandescent lamp comprises a plurality of helically-coiled filament sections (7-10), which are arranged in one or more planes. The filament sections are of varying lengths whereby the array approximates the cross-sectional shape of the light beam which is to be projected by the lamp, as indicated for example by the circle (11).

Abstract: A selected word is stored in a content addressable memory (CAM) by partitioning the word into at least two segments, the segments being individually lesser in width than the CAM but in aggregate greater than the width of the CAM. A first entry in the CAM comprises a predetermined prefix and a first of the segments and a second entry in the CAM comprises a second prefix, corresponding to the address of the first segment, and the second segment. A search key is similarly partitioned. In a first search cycle a first segment of the search key prefixed by the predetermined prefix is applied to the CAM and in the event of a matching entry a second segment of the search key, prefixed by a second prefix comprising an output address word identifying the matching entry, is applied to the CAM in a second search cycle.

Abstract: The invention relates to a feedback circuit for a transimpedance amplifier, which is typically used for converting an input current from a photodiode into an output voltage. The feedback circuit of the present invention linearizes the transconductance feedback, as the input current signal varies, by providing a constant current source for supplementing the DC feedback current through a bypass transistor, thereby reducing a variation in the low frequency cut off.

Abstract: In electrophoretic deposition of a ceramic, the anode is or incorporates a metal which is the same as the metal in the metal salt dissolved in the solvent. Preferably the salt is magnesium nitrate.

Abstract: An optical workstation comprising an optical breadboard supported by a frame, the frame comprising a plurality of upstanding legs interconnected by laterally extending cross-beams, the cross-beams defining a space into which the optical breadboard is received and laterally enclosed. By laterally enclosing the optical breadboard with the cross-beam frame elements, side protection for the optical breadboard is provided, thus protecting it from lateral impacts against which conventional damping mounts are not effective. In addition, since the cross-beams are part of the frame structure, they provide a stable and rigid platform for mounting optical and other components at the very edge of the workstation outside the optical breadboard area. Anchor points in the cross-beams are provided for this purpose.

Abstract: Sulphides are prepared by combining a dithionite compound with an aqueous alkaline solution of an appropriate cation or mixture of cations. On heating the corresponding sulphides are precipitated. The dithionite compound may be a dithionite dianion which is produced as an intermediary when thiourea dioxide is used as a starting material in the solution. Examples of appropriate cations are zinc (as zinc acetate) and copper (as copper acetate). The precipitate is dried and subsequently fired to produce high quality sulphides which may be used as phosphors or other optoelectronic materials.

Abstract: The invention relates to a nuclear plant (8) having a reactor (10) containing a core comprising a plurality of moderator elements in a central region and a plurality of spherical fuel elements located in an annular region around the central region. The plant (8) further includes a fuel and moderator handling system (40) for circulating fuel and moderator elements around the plant (8). It further relates to a method of loading the core with moderator and fuel elements.

Abstract: An incandescent lamp comprises at least four linear, helically-wound filament sections arranged with their longitudinal axes substantially parallel with each other and including a first filament section located along the longitudinal axis of the lamp with the remaining filament sections arranged substantially symmetrically around the first filament section.

Abstract: A filament array for an incandescent lamp comprises at least five filament sections (10) having their longitudinal axes parallel with one another and, when viewed in plan, being arranged substantially symmetrically in a polygonal configuration around the lamp axis. The filament sections are wound from a single wire and are electrically connected together in series by means of linking sections (18, 19, 20) of said wire extending between corresponding ends of the filament sections, with alternate linking sections being positioned at opposite ends of the filament sections. The linking sections at the two ends of the array are supported by a set of support members (30, 31) extending from respective frame members (34, 35). The electrical input and output (14, 15) of the array are through terminal wire sections on opposite or substantially opposite sides of the array.

Abstract: There are disclosed methods, systems and devices whereby SSL or TLS communications between an end-user such as a browsing agent and a small embedded device such as a microcontroller without substantial memory or processing power are made possible. One approach is to provide an interfacing computing device between the end-user and the embedded device comprising an SSL/TLS proxy server/router which translates between a relatively heavyweight encryption protocol used by the end-user and a relatively lightweight encryption protocol used by the embedded device. An alternative approach utilises an SSL/TLS assistant computing device that performs computationally expensive encryption/decryption calculations on behalf of the embedded device.
