Abstract: The present invention relates to a head-worn oxygen tube device that can be used in conjunction with head-worn oxygen tubes or other head-worn masks. The device is primarily comprised of a body with a first end having at least one fastener and a second end having at least one fastener. The device can be worn on the head of the user such that each oxygen tube can be secured by the fastener. Due to the length of the body, each fastener sits above each ear of the user such that each oxygen tube no longer rests on the ears of the user. However, the device still allows a nasal cannula to be worn and used.

Abstract: A filter for an electrostatic precipitator comprising: a plurality of spaced-apart, electrode films having electrical conductivity, arranged to be alternately powered at high and low electrical potentials, each of said electrode films having a leading edge, a trailing edge and two opposing side edges therebetween that extend in the direction of airflow; and first and second pluralities of spaced-apart, rigid isolation members bonded to each of the leading and trailing edges of the plurality of electrode films respectively, wherein each isolation member is bonded, via a substantially continuous, preferably flat, surface thereof, to at least some of said leading or trailing edges, thereby fixing the electrode films in the required spaced-apart arrangement thereof.

Abstract: A hand tool enabling self-aligned placement and post alignment clamping of a surface mounted tooling element and a method for manufacturing such a tool. Using an additive manufacturing process, a tool housing may be manufactured in which one or more internal voids allow insertion and rotational movement along and about a longitudinal axis of the housing, respectively, of a member having a radially extending portion. A handle and a brace may be coupled to the proximal and distal ends of the member to facilitate operation of the tool and placement of the surface mounted tooling element, respectively. Such member may also be spring loaded to enable the tool to clamp itself to a workpiece during the mounting operation, with the radially extending member portion limiting rotational travel of the brace.

Abstract: An auxiliary Powerbox to generate electricity through an additional alternator configuration in an emergency vehicle which reduces fuel consumption and minimizes wear factors associated with idling the engine when the vehicle is at rest and when the vehicle's primary engine is not operating. The system is an auxiliary system that provides electrical power by means of a small internal combustion engine and an alternator and is intended to provide electrical power to a vehicle when the main engine of the vehicle is shut down. The system, the DC Powerbox, has an independent fuel system and cooling system however the fuel and cooling systems could be incorporated into the vehicles respected systems.

Abstract: An air cleaning filter for an air conditioning system comprising a rigid frame having a length, a width and a depth, to which flexible filter material is mounted, the filter material being of greater cross-sectional area than the rigid frame, and including at least two peaks and one trough therein, the maximum peak-to-trough amplitude of which is greater than the depth of the rigid frame. The length and width of the filter are adapted so as to be positioned, in use, in a direction that is substantially perpendicular to the direction of airflow of the air being filtered, whilst the depth thereof is adapted so as to be positioned, in use, in a direction that is substantially parallel to said direction of airflow.

Abstract: A system for enhancing air filter efficiency in an air conditioning apparatus comprising an air conditioning apparatus, having an associated air filter (13), and a dust charging device (5) that is external to the air conditioning apparatus for electrically charging dust particles in air that is drawn into the air conditioning apparatus. Also a method of improving air conditioning air filter efficiency comprising the step of providing a dust charging device for electrically charging dust externally of an air conditioning apparatus, having an associated air filter, and in a position to charge dust particles in air that is drawn into the air conditioning apparatus.

Abstract: A state table includes a plurality of possible states of a computer system and the corresponding actions which produce transitions between source and target states. A set of test programs is stored, each test program performing an action in the state table. A test selects an action corresponding to the current state of the computer system; executes the test program which performs the selected action; determines the state of the computer system after the test program has executed; and compares the determined state to the state indicated in the state table as the target state to the selected action on the source state. When an error is found, instead of stopping execution, the test operations to be performed are dynamically reconfigured. Weightings are dynamically allocated to actions in the state table to create a weighted set, and selection of the next test is carried out using random selection over the weighted set.

Abstract: The present invention provides a method, apparatus and computer program product for combining a plurality of run units into a single executable file. According the invention each run unit may contain one or more data entities which are designated as being required only once in an executable file. As a result when the executable file is built, if a run unit with a data entity of a given value is to be added to an executable file, if a previous run unit with a data entity with a matching value has previously been added to the executable file, the run unit is added to the executable file but without the data entity.

Abstract: A closure for the open mouth of an airtight container. The closure has a resiliently flexible diaphragm which has a peripheral edge (37) which can sealing engage against an inside wall surface of the open mouth. The diaphragm (13) is engaged with the second cover section (12) of a cover. A pair of toggles (24) are pivotally mounted on axles (22) of second cover section (12). The levers (30) of the toggles (24) extend through an opening (44) in the first or outer cover section (11) when the first and second cover sections (11,12) are snap-locked together. By moving the levers (30) toward one another the respective feet (27) of the toggle (24) engage with area (35) of the diaphragm (13) to deform the diaphragm and thereby break a sealing effect between the peripheral edge of the diaphragm and the inside wall surface of the open mouth.

Abstract: A particle precipitation device for removing particles entrained in a gas stream includes an array of passages through which a gas stream can be directed relatively freely. The passages are provided between plastics walls adapted to create an electrical field within the array. The plastics walls may have areas of conductive material in contact therewith. High and low electrical potentials alternately applied to isolated areas of the conductive material provide charged sites in the array for collecting particles from the gas stream. Alternatively, the plastics walls may have electret properties.
