Automated Irrigation Classification Using NDVI and Decision Trees
THE UNIVERSITY OF MELBOURNE
13 February 2025
Summary
This patent describes an automated method for classifying the irrigation status of agricultural fields using satellite imagery. The system analyzes seasonal Normalized Difference Vegetation Index (NDVI) [a measure of plant greenness] data to determine if a field is irrigated or not. It identifies field boundaries, processes NDVI time series data to generate aggregate field NDVI feature values, and then uses a decision tree classifier to classify the irrigation status based on these values. This allows for efficient monitoring of irrigation practices over large geographical areas.
Sample uses of this patent

Improving water resource management and conservation.
Providing data for precision agriculture and crop yield optimization.
Measuring Geomaterial Properties During Compaction Using Distance Sensors
MONASH UNIVERSITY
13 February 2025
Summary
This patent describes a system for measuring the properties of geomaterial [soil and rock] layers during compaction. It uses a distance sensor to measure deformation (change in shape/size) of the material as it is compacted. An electronic processing system receives signals from the sensor and calculates properties like density, stiffness, or thickness based on a predefined relationship or model. The system can be mounted on a moving platform and incorporate motion sensors to correct for movement. It can also use geolocation to create maps of geomaterial properties.

13 February 2025
Summary
This patent describes an apparatus and method for enhancing the movement (motility) of flagellar cells, particularly sperm cells, using ultrasound.

The key innovation lies in using focused ultrasound to stimulate the cells, potentially improving their fertilization capabilities or assessing their viability. The method involves exposing the cells to these ultrasound waves, optimizing parameters like frequency and duration based on cell type, and using a computer system for precise control.

Treating Fatty Liver Disease by Inhibiting PSMD9 Using Modified Oligonucleotides
THE UNIVERSITY OF SYDNEY
11 February 2025
Summary
This patent describes a method for treating hepatic [liver] lipid dysregulation (imbalance) or the risk thereof by administering a PSMD9 inhibitor. The PSMD9 inhibitor is a polynucleotide, specifically a modified oligonucleotide, that targets PSMD9. The key innovation lies in using PSMD9 inhibition as a therapeutic strategy for metabolic disorders like fatty liver disease, which are associated with disrupted lipid homeostasis [the body's ability to maintain balance in fat metabolism]. The method involves administering the PSMD9 inhibitor to reduce the accumulation of pathological lipid species [harmful fats] and markers of NASH (nonalcoholic steatohepatitis) or T2D (type 2 diabetes), such as inflammation, fibrosis [scarring], ER stress [stress on the endoplasmic reticulum], or elevated glucose levels. The effectiveness of the treatment can be monitored by measuring lipid species levels or markers of inflammation, fibrosis, ER stress, T2D, or insulin resistance.
Sample uses of this patent

Improving Wireless Reception by Estimating Channel Characteristics
UNIVERSITY OF NEW SOUTH WALES
6 February 2025
Summary
This patent describes a wireless receiver that uses a Delay Doppler channel detector to improve signal reception. The key innovation lies in estimating the channel gain, delay, and Doppler frequency shift [the change in frequency of a wave in relation to an observer who is moving relative to the wave source] of the received data. By accounting for these factors, the receiver can more accurately extract the transmitted symbol sequence, leading to better communication quality. The system also uses pilot symbols [a known sequence of symbols] and frame synchronization to optimize the sampling window and further enhance signal processing.

Fabricating Nanopores by Irradiation and Etching for Nanofiltration
AUSTRALIAN NATIONAL UNIVERSITY
6 February 2025
Summary
This patent describes a method for creating nanopores [tiny holes with dimensions in nanometers] in a material, specifically focusing on amorphous inorganic materials like silicon-based compounds and inorganic oxides. The process involves two main steps: first, the material is irradiated to create a track of damage at the nanoscale. Second, this track is etched using a chemical etchant to form the nanopore. The geometry of the nanopores (cone angle, radius, symmetry) can be tuned by controlling parameters like material composition, temperature, and etchant properties. The key innovation is a controlled method for nanopore fabrication and tuning in amorphous materials.
Sample uses of this patent
Creating filters for selective separation of molecules or particles based on size.
Developing sensors for detecting specific molecules or ions by measuring changes in electrical current through the nanopore.

Tuning Linearity for Quantum Magnetic Field Detection Using Electrostatic Gating of SQUIDs/SQIFs
THE UNIVERSITY OF ADELAIDE
6 February 2025
Summary
This patent describes a quantum magnetic field receiving device that utilizes a Superconducting Quantum Interference Device (SQUID) or a Superconducting Quantum Interference Filter (SQIF) and an electrostatic gating circuit. The key innovation lies in the use of the electrostatic gating circuit to apply electrostatic fields to the Josephson Junctions within the SQUID or SQIF. By tuning the critical supercurrents of these junctions, the linearity of the magnetic flux-to-voltage response of the device is improved. This tuning optimizes the Spurious Free Dynamic Range, enhancing the device's performance in detecting weak magnetic signals. The device aims to improve the sensitivity and accuracy of magnetic field measurements by using electrostatic gating to precisely control the properties of the Josephson Junctions. This allows for fine-tuning of the device's response, leading to better signal detection and reduced noise. The application of electrostatic fields enables the adjustment of critical supercurrents and inductances within the SQUID or SQIF, ultimately enhancing the overall performance of the quantum magnetic field receiving device.

Targeted Delivery of Radionuclides Using Dual Chelating Ligands for Imaging and Therapy
THE UNIVERSITY OF SYDNEY
23 January 2025
Summary
This patent describes compounds designed to deliver radioactive isotopes to specific sites in the body, particularly for cancer therapy and diagnostics. The key innovation lies in a single molecule with two different chelating ligands [a molecule that can bind a metal ion]. One ligand selectively binds Zirconium-89 (89Zr), useful for imaging, while the other binds a therapeutic radionuclide [radioactive isotope] like Yttrium-90 (90Y) or Lutetium-177 (177Lu). A linker connects these two ligands, and this linker can be modified to attach targeting moieties [molecules that guide the compound to specific cells or tissues, like antibodies]. This allows for simultaneous imaging and therapy, or the delivery of a therapeutic isotope after initial imaging confirms targeting.
