    Abstract: A sensing element is provided for use in a system for measuring fluid flow, such as, turbulent air flow. The sensing element comprises a sensor body and a first load cell arrangement connected to the sensor body. The sensor body has a three dimensional shape which is rotationally symmetric about a longitudinal axis passing through the first load cell arrangement and the sensor body. The first load cell arrangement is configured to measure the force exerted on the sensor body by fluid flow in at least an xy plane perpendicular to the longitudinal axis. A system for measuring fluid flow comprising the sensing element and a method for measuring fluid flow using the sensing element and the system are also provided.

    Abstract: A laser detector apparatus (1) is provided, where a pixel array (3) is arranged behind a lens arrangement (4) such that distant objects (9) (in general, those at infinity) are out of focus at the pixel array. The image from the pixel array is evaluated by a computer processor (6) to detect such out of focus images which will be of a known size and shape (generally circular spots of known width). This can enable distant laser threats to be readily distinguished from nearby bright objects (10), whilst also protecting the pixel array from powerful laser sources (because the laser energy is not focussed to a point, on the pixel array it is less likely to damage the pixel array). It can also enable the wavelength of the laser to be accurately determined from the ratio of colours in the image of the laser spot, because it will typically not be a saturated image. The apparatus and method are particularly suitable for identifying and distinguishing laser sources across a wide range of brightnesses, and is also suitable for detecting and distinguishing multiple laser sources.

    Abstract: There is provided an animal training system to train an animal to detect a training odor. The animal training system comprises a target (310) comprising the training odor (320) and a hidden marker (330); and a detector (350) for identifying the hidden marker. There is further provided an animal training method using the animal training system, the animal training method for practice by a supervisor, an animal handler, and an animal. The animal training method comprises placing the target (310) in a location of a search area (300), the target comprising the training odor (320) and the hidden marker (330), the placing being carried out by the supervisor; introducing the animal handler and the animal (305) to the search area; scanning with the detector (350) a candidate location for the hidden marker, the candidate location being a location that is indicated by the animal; and rewarding the animal if the detector indicates the presence of the hidden marker at the candidate location.
