Abstract: Apparatus, e.g. a syringe, for dispensing foam includes means for ensuring that only foam of adequate quality is dispensed. In use, the syringe may be filled from a pressurised canister which generates foam e.g. for therapeutic use in treating varicose veins. An initial quantity of foam dispensed from the canister may be of inadequate quality in which case it should not be used: the syringe includes means to ensure that this initial quantity of foam is diverted to a waste port or to an internal waste chamber e.g. located in the syringe plunger. Foam dispensed after the initial quantity of poor quality foam is stored in the main barrel of the syringe ready for administration to a patient in need of treatment.

Abstract: A breath-actuated delivery device includes a mouthpiece through which a subject in use exhales, an air channel which is in fluid communication with the mouthpiece, and a flexible diaphragm which is disposed in the air channel. The diaphragm provides for at least a restricted air flow through the air channel until a predeterminable actuation pressure is developed in the mouthpiece, and, on generation of the predeterminable actuation pressure in the mouthpiece, provides for an air flow through the air channel.

Abstract: A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank. In some embodiments, the vehicle illumination optics can include a primary illumination group and a plurality of side illumination groups.
