  • Publication number: 20220381893
    Abstract: An e-commerce business model has witnessed several cases where packages with faulty goods, returned by buyers, without procured object, rather replaced by different device. This disclosure relates a method to detect whether object under test a desired object. A plurality of back-scattered signals is received from the object under test occluded by packaging with continuous motion on conveyer based on first antenna-radar combination. The plurality of back-scattered signals is processed by applying four-tap difference filter to obtain motion-filtered data matrix. A low pass filter is applied on the motion-filtered data matrix to obtain enveloped motion-filtered data matrix. A sliding constant false alarm rate is applied on the enveloped motion-filtered data matrix to determine detection threshold value. A check is performed to detect whether the object under test is the desired object based on whether intensity of the plurality back-scattered signals exceeds the detection threshold value.

  • Patent number: 11375021
    Abstract: Any sensing system is faced with triangle of dilemma between accuracy, latency and energy. High energy and high latency sensing systems are often very accurate but less useful. Embodiments herein provide a method and system for edge based sensor controlling in the IoT network for event monitoring. The system disclosed herein applies a hierarchical sensor selection process and adaptively chooses sensors among multiple sensors deployed in the IoT network. Further, on-the-fly changes operation modes of the sensors to automatically produce the best possible inference from the selected sensor data, in time, power and latency at the edge. Further, sensors of the system include a waveform and diversity control mechanism that enables controlling of an excitation signal of the sensor.

  • Patent number: 11046733
    Abstract: The present invention relates to compositions comprising CpG rich DNA from Pseudomonas aeruginosa. The compositions optionally comprise a cupredoxin. The present invention includes specific CpG DNAs from Pseudomonas aeruginosa that are useful for treating cancer and other conditions in patients. These compositions are optionally in a pharmaceutically acceptable carrier and also optionally comprise a cupredoxin. The present invention further relates to methods to express proteins near cancer cells. These methods may be used to express therapeutic or diagnostic proteins near cancer cells in a patient suffering from cancer or other conditions, and can also be used for diagnosing cancer in a patient. This method uses the gene for azurin from P. aeruginosa as an expression system for azurin or heterologous proteins in P. aeruginosa or heterologous cells.

  • Patent number: 11007165
    Abstract: Liquid nutritional compositions include functional ingredients such as beta-hydroxy-beta-methylbutyrate, docosahexaenoic acid, and lutein. The nutritional compositions are useful to promote at least one of physical performance (e.g., body composition, muscle mass, muscle strength) and cognitive function (e.g., focus, attention, alertness, executive function) in an individual. The functional ingredients are incorporated into the nutritional composition in such a way that they do not adversely affect the desirable properties of the nutritional composition such as, for example, nutritional value, stability, solubility, taste, and mouthfeel.

  • Patent number: 10590177
    Abstract: The present invention provides modified cupredoxin derived peptides with pharmacologic activity that have improved pharmacokinetic properties, and methods to use them to treat mammals suffering from various conditions related to the pharmacologic activities. Modifications of the cupredoxin derived peptides include amino acid sequence variants and structural derivations that increase the plasma half-life of the peptide, increase the specific activity of the pharmacologic activity, decrease immunogenicity, and decrease the biotransformation of the peptides. The modified cupredoxin derived peptides can be used in methods to treat mammals for cancer, conditions elated to inappropriate angiogenesis, viral and bacterial infections, and specifically HIV and malaria, conditions related to ephrin signaling, and to deliver cargo compounds, including diagnostic compounds, to cancer cells.
