Abstract: A system for dispensing a pest attractant or repellent into a surrounding environment, comprising: a main reservoir for storing a fluid; a control volume coupled to the main reservoir, a first flow restrictor arranged to regulate a flow of the fluid between the main reservoir and the control volume; a second flow restrictor arranged to regulate a flow of the fluid out of the control volume; and, an evaporation medium positioned at or downstream of the first flow restrictor, wherein at least one of the first and the second flow restrictors is a controllable flow restrictor, and wherein the system further comprises electronically controllable actuation means for actuating the controllable flow restrictor.

Abstract: A system for detecting the presence of pests. In one aspect the system comprises an imaging system including: a housing including one or more pest entrances; a pest attractant arranged within the housing; a pest detection surface; an image capture device, said image capture device being configured to capture one or more images of the pest detection surface; and a triggering sensor arrangement for detecting a target pest that is on or about to enter the pest detection surface, said triggering sensor arrangement being configured to provide a trigger-signal if the presence of an object is detected, the image capture device being configured to take an image of the pest detection surface in response to the trigger-signal.

Abstract: A system for detecting the presence of pests, the system comprising: at least one remote camera system, each of the at least one remote camera system comprising an image capture device coupled to a processor and a wireless transmitter, each of the at least one remote camera system having a pest detection surface and being configured to: capture one or more image of the pest detection surface; process the captured one or more image to recognise the potential presence of a target pest on the pest detection surface; and transmit data from the captured one or more image in response to recognising the potential presence of one or more target pests; and a server configured to: receive the transmitted data; process the transmitted data to verify the potential presence of the target pest on the pest detection surface; and provide an output indicating the verification.

Abstract: A system/method for producing a substance attractive to one or more species of insect characterised by: housing a population of live insects; providing any combination of nutrients, food or water to the live insects; removing organic matter from the population; and sterilizing the removed organic matter.

Abstract: Method and apparatus relating to ultrasound flow probes Measurement of time of flight of ultrasound pulses comprises: transmitting the pulses across a fluid flow; detecting a waveform (200) of the pulses, generating a cross-correlation between the waveform (200) and a tone (210) and identifying a plurality of peaks (220) in the cross-correlation; fitting a curve template (310) to the waveform at locations (300) corresponding to the peaks (220) and identifying the location (330) of the minimum error; performing a further cross-correlation (420) between the waveform (200) and the tone (210) over only a portion of the waveform (200) containing the minimum error location (330); and determining the temporal location corresponding to the maximum (430) of the further cross-correlation (430).

Abstract: A lens system comprises a first electro-active lens comprising a first focus sensor coupled to a first processor and a second electro-active lens comprising a second focus sensor coupled to a second processor. The first focus sensor periodically generates electromagnetic signals and detects electectromagnetic signals generated by the second focus sensor. The second focus sensor periodically generates electromagnetic signals and detects electectromagnetic signals generated by the second focus sensor. The first processor receives an indication of the second electromagnetic signals and, based on the received indication of the second electromagnetic signals, determines a relative convergence angle between the first and second electro-active lenses. Based on the determined relative convergence angle, the first processor determines a focal setting for the first electro-active lens and controls an electroactive element in the first electro-active lens, based on the determined focal setting.
