Abstract: This apparatus produces a capnogram for a patient, comprising airflow means arrangeable such that air flowing into and out of a patient during a breathing cycle of the patient are conducted through the airflow means; a CO2 monitor (50) for repeatedly determining the presence, and level, of CO2 in the air within the airflow means; an airflow direction sensor for distinguishing between periods when air is flowing into the patient, when air is flowing out of the patient, and when air in the airflow means is stationary; a processor for producing a graph on a display of time versus an indication of CO2 levels, wherein the display includes different graphical qualities to distinguish between the level of CO2 in the air flowing out of the patient, the level of CO2 in the stationary air between breaths, and the level of CO2 in the air flowing into the patient.

Abstract: The invention is directed to a system and method of asynchronously collecting different types of information for an event (e.g., football game) and aggregating the information in real-time according to sub-events (e.g., plays from scrimmage). One or more terminals (e.g., smartphones, tablet or laptop computers) are configured to capture information (video, still images, metadata) of each sub-event and distribute the captured information to the other terminals in real-time. Such distribution may be facilitated using a cloud network and server, or else a peer-to-peer (P2P) network. Further, one of the terminals is configured to notify the other terminals when a particular sub-event has commenced, thus allowing the captured information of the particular sub-event to be associated with a corresponding sub-event identifier. The captured information may be aggregated according to the sub-events by use of sub-event identifiers for presentation to users, e.g., in a playlist.

Abstract: A method of determining the viability of an egg at least approximately 50% through its incubation period, which method comprises the steps of: (a) causing electromagnetic radiation to impinge upon the egg, the electromagnetic radiation having one or more wavelengths in the infra-red part of the spectrum; (b) receiving at least a part of the infra-red radiation that has passed through the egg and generating an output signal representative of the received infra-red radiation; and (c) processing said output signal to determine whether there is a cyclical variation in the intensity of the infra-red radiation leaving the egg corresponding to action of a heart, the existence of said cyclical variation indicating that the egg is viable; wherein step (a) is performed by directing infra-red radiation so that it passes through the shell for reflection from an outer surface of a vascular structure adjacent an inner surface of said shell, and step (b) is performed by receiving any infra-red radiation so reflected.

Abstract: An apparatus (10) for determining the viability of an egg, which apparatus (10) comprises shielding means (12, 14), emitting means (30) and detecting means (32), the arrangement being such that, in use, the shielding means (12, 14) inhibits exposure of an egg to background infra-red radiation, said emitting means (30) can emit electromagnetic radiation at infra-red wavelength(s) to impinge on the egg, and the detecting means (32) are positioned to detect at least a part of said electromagnetic radiation that has passed through the egg, the apparatus further comprising means for processing an output signal of the detecting means to determine whether there is a cyclical variation in the intensity of the infra-red radiation leaving the egg corresponding to action of a heart, the existence of said cyclical variation indicating that the egg is viable.

Abstract: A positive pressure test apparatus for fit testing a facepiece respirator having an exhalation valve, including a cover portion having a central bore with an inwardly directed shoulder at the base. A plunger is provided having a stem, a button portion on one end and a flange portion on the opposite end. The stem is situated within the central bore, the button portion extending above the surface of the cover portion in a rest position, and the flange portion extending below the inwardly directed shoulder. Bias means are located in engagement with the button portion and the shoulder for biasing the plunger from the rest position to a depressed position, wherein the button is flush with the surface of the cover portion and the flange portion seals the exhalation valve. A mounting means is provided to attach the positive pressure test apparatus to the respirator.

Abstract: A positive pressure filter respirator includes a full face mask comprising an outer mask 1 and an inner orinasal mask 2. A filter canister 5 is screw mounted to an air inlet 4, and a centrifugal fan 6, which is driven by a battery operated motor 7, is so arranged as to draw air through the filter canister 5 into the outer mask 1. The filter life and the battery life are extended by the use of a pressure responsive means which responds to the difference in pressure between the pressure in the interior of the orinasal mask 2 and the pressure in the space 20 within the outer mask 1 and outside the orinasal mask 2. The pressure responsive means reacts immediately to the commencement of either exhalation or inhalation to disable the fan 6 or on commencement of exhalation and to accelerate the fan 6 on commencement of inhalation.

Abstract: A layer of a non-woven or open-woven or open-knitted charcoal cloth is supported on a layer of a textile material having fibers needle-punched through the charcoal cloth. This composite material can be incorporated in various multi-layer structures having, for example, a further textile layer and/or a microporous or similar layer on the other side of the charcoal cloth. Such multi-layer structures may be used in protective clothing, as filter materials or in medical dressings, or in the manufacture of moulded articles such as face masks.

Abstract: Activated carbon is made by pre-treating a fibrous cellulose material with a Lewis acid comprising one or more selected halides, drying and softening the treated material, suspending the material from a frame in a tensionless manner, heating the suspended material in a furnace to effect carbonization of the cellulosic material in an environment which is substantially non-reactive towards that material, activating the suspended carbonized material at an elevated temperature in an atmosphere comprising an activating gas until the desired degree of activation has been produced, and thereafter cooling the furnace, the furnace having at least one heating element at its base and at least one heating element arranged on or in a side wall, each heating element being spaced apart from the suspended material.

Abstract: An adsorptive device having at least one composite adsorptive element through which gas can pass comprising a bed of granular adsorptive carbon and a bed of fibrous adsorptive carbon.
