Abstract: An apparatus for determining an index of insect biodiversity, comprising: a plurality of optical insect sensor devices configured to be individually positioned within a geographic area, each insect sensor device configured to: monitor insect activity within a detection volume extending outside the insect sensor device by detecting light from the detection volume, and to output detector data indicative of one or more optically detected attributes associated with respective detected insect detection events, each insect detection event being indicative of one or more insects being present in the detection volume; a data processing system communicatively coupled to the plurality of optical insect sensor devices and configured to: receive detector data from respective ones of the plurality of optical insect sensor devices, the detector data being indicative of one or more optically detected attributes associated with respective detected insect detection events, and to compute, from the received detector data, an i

Abstract: An apparatus for detecting and identifying moving organisms, the apparatus comprising: an illumination module configured to illuminate a target space; a detector module comprising an imaging system and an image sensor, the detector module being configured to capture a plurality of images of the illuminated target space, the target space comprising one or more organisms moving about said target space; a processors configured to: detect, from the captured images, a trajectory of an organism moving about said target space; recognize a type of organism from the detected trajectory.

Abstract: An apparatus for dispensing an insecticide across an area of land; the apparatus comprising a vehicle configured to travel along a travelling path across the area of land, the vehicle defining a direction of travel, the vehicle comprising an insecticide dispensing device configured to dispense an insecticide along said traveling path when the vehicle travels along the travelling path; a dispensing control system configured to control an amount of insecticide to be dispensed when the vehicle travels along the travelling path; an insect sensor configured to detect insects in a detection volume; wherein the detection volume is located in front of the vehicle relative to the direction of travel; wherein the dispensing control system is configured to receive sensor data from the insect sensor, the sensor data being indicative of detected insects in the detection volume, and to control the amount of dispensed insecticide responsive to the received sensor data.

Abstract: A water saver unit for use with a flush toilet having a tank, a flush handle, a tank drain opening and a flapper valve support, with a flapper valve having a flapper element for mounting on the flapper valve support, and a strap for connecting the flapper element to the flapper handle, with the flapper element having a solid disk with upper and lower surfaces, a center section and a rim, with radially extending ribs on the upper surface between the center section and rim, and with the bottom surface tapering downward from the rim toward the center section. A float is positioned on the strap to provide bouyancy to the flapper valve as long as the float is below the water level in the toilet tank. The flapper element solid disk is of substantially uniform thickness between the center section and rim, and the bottom surface taper is in the order of 5 to 20 degrees, preferably about 10 degrees.

Abstract: A pour dispenser for pouring fluid from a container and including a body having an outlet nozzle and adapted for mounting on a container, a piston in the body and slideable between a valve open condition providing a first flow path between the container and the nozzle and a valve closed condition blocking fluid flow between the container and the nozzle, a plunger in the piston and slideable between a valve open condition providing a second fluid flow path between the container and the atmosphere and a valve closed condition blocking fluid flow between the container and the atmosphere, and springs between the plunger, piston and body for urging the plunger and the piston to the valve closed conditions, with plunger actuation opening the second fluid flow path and then opening the first fluid flow path.
