Abstract: Methods and systems are provided for monitoring a tracer within a monitored system that includes at least three barrier layers and at least three corresponding tracers. The barrier layers—referred to as a first, second, and third barrier layer—may each have an initial association with a different one of the three tracers. The methods and systems may further enable detection, such as after the monitoring step, of a tracer at a location outside its initial associated barrier layer, where the detected tracer may be one of the three tracers. In certain embodiments, additional barrier layers and/or additional tracers may be employed, and interactions between and/or among them may allow determination of the location, concentration, amount, and identity of one or more traced compositions, including, for example, identification of breaches, within sealable monitored systems.

Abstract: Disclosed are methods and systems for monitoring a tracer in a monitored system having at least three three barrier layers and at least three tracers, wherein for the at least three barrier layers those barrier layers may be called a first barrier layer, a second barrier layer, and a third barrier layer, wherein each of these barrier layers has an initial association with a different one of the three tracers. Further, the disclosed methods and systems may detect, subsequent to the monitoring, the tracer at a location that is external to the initial association for the different one of the three tracers, wherein the tracer is one of the three tracers. In various example embodiments, the methods and systems may include more barrier layers and/or more tracers, whereby interactions therein permit determination of location, concentration, amount, and identity of traced composition(s), including breaches, in sealable monitored systems.

Abstract: The invention may provide methods of characterising and/or optimising a well treatment. The method comprises calculating, estimating and/or determining at least one spatial or temporal tracer distribution moment for at least one tracer in a well before the well treatment and calculating, estimating and/or determining at least one spatial or temporal tracer distribution moment for the at least one tracer introduced into the well at a later stage or later portion of the well treatment or after at least well treatment stage has been completed or approaching completion. The method comprises comparing the at least one spatial or temporal tracer distribution moment of the tracers to estimate at least one characteristic of the well treatment.

Abstract: Systems and methods for air pressure control in a hot melt liquid dispensing system are described. An example hot melt liquid dispensing system includes a pump that pumps hot melt liquid to an applicator. The hot melt liquid dispensing system also includes an air flow path that supplies pressurized air to the pump and an electronic pressure sensor associated with the air flow path. The hot melt liquid dispensing system also includes a controller that receives an electronic signal from the electronic pressure sensor indicative of an air pressure in the air flow path and causes adjustment to the air pressure in the air flow path based on the electronic signal from the electronic pressure sensor.

Abstract: A method of making an electrode for a wearable electronic includes providing an adhesive print media layer. A surface treatment is performed to a top surface of the print media layer. An elastic conductive ink is deposited onto the print media layer. The elastic conductive ink comprises a conductive particulate disposed in a binder. A diffusion bond is formed between the top surface of the print media layer and the elastic conductive ink. The diffusion bond forming is facilitated by the surface treatment and even after the diffusion bond is formed, the top surface of the diffusion bonded electrode remains conductive.

Abstract: A system for generating variable frequency tube waves includes a high pressure multiplex pump having a number of plungers, with each plunger operatively coupled to a suction valve on a suction side and a discharge valve on a discharge side.

Abstract: Systems and methods are disclosed method for controlling instantaneous current changes in parallel processors with arrays of parallel computing elements, such as neural processors. An exemplary method comprises monitoring the array of computing elements and determining a transition from a first activity level of the array to a second activity level of the array, such as an idle-to-active or active-to-idle transition. Once a transition is determined, the array is selectively controlled to minimize the instantaneous current change from the transition from the first activity level to the second activity level.
