Patent number: 9915638Abstract: A food expiry label includes a layer of material (such as a water-swollen mammalian gelatine) that undergoes a phase transition (such as from solid to liquid) upon exposure to bacteria or fungi that result in food spoilage. The label may incorporate a tactile surface that the user can feel underneath the layer of gelatine once the gelatine has changed from solid to liquid. Thus a user can detect when a foodstuff is likely to have spoiled or been on the shelf for a predetermined period simply by feeling the label.Type: GrantFiled: May 20, 2015Date of Patent: March 13, 2018Assignee: Mimica Lab LtdInventor: Solveiga Pakstaite

Patent number: 9915639Abstract: This agricultural device introduces an innovative approach to soil treatment that restores the fertility of depleted soils, which currently depend on chemical fertilizers to keep up with global food production needs. The new technology is based upon the concept of bioenergetics, whereby soil is conceived as the main factor that needs to be balanced in order to increase natural soil fertility, crop production, and food quality. This scientifically-based farming technology utilizes horizontal tillage—as opposed to conventional tillage—to reduce the entropy of the soil-plant-atmosphere system, helping regenerate biological memory and natural soil fertility.Type: GrantFiled: March 11, 2015Date of Patent: March 13, 2018Inventor: Heriberto Bouza Gonzalez

Patent number: 9915640Abstract: A system and a process for detecting early stage electrical components problems with an analysis system is disclosed. The system process includes determining an oil quality of the oil of an electrical component using the analysis system. The system the process further including determining dissolved gases in the oil of the electrical component using the analysis system, processing and analyzing the oil quality and the dissolved gases using the analysis system, and determining whether there are problems in the electrical component using the analysis system.Type: GrantFiled: December 5, 2016Date of Patent: March 13, 2018Assignee: SPX TRANSFORMER SOLUTIONS, INC.Inventors: John Pruente, Nuwan Rodrigo

Patent number: 9915641Abstract: Methods and apparatuses for sensing biological functions are disclosed. Sensors can be implanted in an organ, such as the brain, and a magnetic field gradient applied to the biological tissue. The field causes the sensors to have different resonant frequencies allowing their spatial localization. The sensors can harvest power from the external coils to be able to retransmit data.Type: GrantFiled: December 4, 2014Date of Patent: March 13, 2018Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: Mikhail Shapiro, Azita Emami, Manuel Alejandro Monge Osorio

Patent number: 9915642Abstract: A method of assessing a tissue sample includes the steps of: 1) splitting source electromagnetic radiation into: a) sample arm radiation directed in a Z direction toward a sample thereby illuminating the sample at a first selected XY coordinate pair of the sample, and b) reflector arm radiation directed toward a reflector so that the reflector arm radiation travels a path length; 2) interfering sample-scattered electromagnetic radiation with reflector-reflected electromagnetic radiation thereby establishing an interference pattern associated with the sample; 3) comparing the sample interference pattern to a reference interference pattern; and 4) reaching a conclusion about the sample based on the comparison.Type: GrantFiled: April 5, 2016Date of Patent: March 13, 2018Assignee: Hill-Rom Services, IncInventor: David Ribble

Patent number: 9915644Abstract: A method and system for remotely monitoring intoxication of a user, comprising: prompting the user to provide a breath sample at a time point; at a breath sample acquisition device, generating a breath sample signal upon reception of the breath sample from the user, and broadcasting a unique signature proximal in time to the time point; using a sensor of a mobile computing device, generating an authentication signal derived from detection of the unique signature; at a processing system in communication with the mobile computing device and the sample acquisition device, receiving the breath sample signal and the authentication signal; generating a verification assessment that validates provision of the breath sample by the user; determining a value of an intoxication metric for the user based upon the breath sample signal; and transforming the verification assessment and the value of the intoxication metric into an analysis of intoxication of the user.Type: GrantFiled: December 17, 2015Date of Patent: March 13, 2018Assignee: KHN Solutions, Inc.Inventors: Keith Harry Nothacker, Pauline Anne Basaran, Stacey Ilene Rettus, Zachary Michael Saul

Patent number: 9915645Abstract: This invention relates to a method for detecting the presence of or likelihood of a patient of developing occult pancreatic beta cell dysfunction, and a method for detecting the presence of or likelihood of a patient of developing clinically significant post-prandial hyperglycemia. The methods involve (a) measuring a level of alpha-hydroxybutyrate (AHB) in a single fasting baseline biological sample of the patient; (b) comparing the level of AHB in the single fasting baseline biological sample to a reference AHB level; and (c) determining the presence of or likelihood of developing the disorder in the patient based on the comparison in step (b). An increased AHB level at fasting baseline indicates that a normoglycemic, normo-insulinemic and/or non-dyslipidemic patient has developed or has an increased likelihood of developing occult pancreatic beta cell dysfunction.Type: GrantFiled: January 13, 2014Date of Patent: March 13, 2018Assignee: True Health IP LLCInventors: Steve Varvel, Rebecca E. Caffrey, James V. Pottala
