Abstract: A low pressure drop device for personal protection against toxic industrial chemicals and chemical warfare agents has a flexible polymer hood impermeable to toxic challenge molecules, a neck seal for sealing the hood about the neck, a half mask for connection to a canister and a low pressure drop canister for chemical protection. The canister contains carbon monoliths of 5- 40 mm diameter, length 1-3 cm, open area 30-60%, surface area ?700 m2/g optionally activated to >30 wt % weight loss and optionally impregnated with metallic additives and/or triethylene diamine. The monoliths have square channels of size 100-2000 ?m and wall thickness 100-2000 ?m. It also contains a resiliently flexible closed cell foam with holes slightly smaller than the monoliths so that flow through the canister is through the monoliths.

Abstract: The invention relates to a low pressure drop personal protection device for providing protection against a range of toxic industrial chemicals and chemical warfare agents and capable of being worn by a wide range of users. The device comprises: a flexible polymeric hood in which the polymer is selected to be impermeable to the toxic challenge molecules; a neck seal for sealing the hood about the neck;a half mask for providing connection for a canister; and a low pressure drop canister system for providing chemical protection. The canister may comprise a resiliently flexible, closed cell foam and monolithic activated carbons, the foam having holes slightly smaller than the size of the monoliths so that flow through the canister is through the monoliths.

Abstract: In the field of vehicle occupant detectors there is a need for an improved vehicle occupant detector which is able to consistently identify the number of occupants in vehicles having windscreens with different infrared transmission characteristics. A vehicle occupant detector comprises a first infrared illuminator that is operable at a first infrared wavelength to illuminate an interior of a vehicle, and a second infrared illuminator that is operable at a second infrared wavelength to illuminate an interior of a vehicle. The vehicle occupant detector also includes a first infrared detector to capture a first image of the interior of the vehicle illuminated at the first infrared wavelength, and a second infrared detector to capture a second image of the interior of the vehicle illuminated at the second infrared wavelength. The first and second infrared detectors have the same infrared detection characteristics.

Abstract: A breast support arrangement comprises a first breast cup which is connected with a first wing portion, and a second breast cup which is connected with a second wing portion. A connecting member passes from the first breast cup to the second breast cup via the second wing portion then the first wing portion; is moveable relative to each of the first and second wing portions; and is or includes an elastic member to draw the first breast cup towards the second wing portion, the second breast cup towards the first wing portion, and the first and second wing portions towards one another. Each wing portion includes a wing guide to couple the connecting member to the wing portion and guide movement of the connecting member relative to the wing portion. Each wing guide includes a guide body which defines a rigid guide portion to receive the connecting member.

Abstract: A breast support arrangement comprises a first breast cup which is connected with a first wing portion and a second breast cup which is connected with a second wing portion. The first and second connecting members on the brassiere are cooperable with one another to couple the first and second wing portions to one another. At least one of the first and second connecting members can include an elastic member to, draw the first breast cup towards the first wing portion, the second breast cup towards the second wing portion, and the first and second wing portions towards one another. Each wing portion includes a wing guide to couple the corresponding connecting member to the wing portion and guides movement of the respective connecting member relative to the corresponding wing portion. Each wing guide includes a guide body which defines a rigid guide portion to receive the corresponding connecting member.
