Abstract: The disclosed computer-implemented methods and systems provide solutions for mitigating misdetection of display devices in connection with a subscription service. In some examples, the described methods and systems receive a content request from a display device, where the content request is correlated with a particular subscription service account. In some examples, the systems and methods further determine that the display device is not associated with the particular subscription service account. To verify the display device, the systems and methods utilize display timings and scan timings associated with a verification token to prove that the display device is validly located and can therefore be trusted in connection with the subscription service account. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Systems and methods for continuously monitoring mass loss through flow erosion of a well equipment component are provided. The disclosed system includes a wear transducer mounted to the equipment component proximate a portion of the equipment component exposed to erosive fluid flow. The wear transducer includes a metal coupon including an elongated end that extends into a flowpath of the equipment component such that the elongated end is exposed to the erosive fluid flow. The wear transducer also includes an ultrasonic sensor disposed within the metal coupon. The ultrasonic sensor transmits ultrasonic signals through the metal coupon toward the elongated end and receives ultrasonic signal reflections reflected back from the elongated end.

Abstract: Systems and methods for incorporating multiple single-port vector network analyzer modules where the modules can be located at significant distances from each other. Systems and methods are provided for synchronizing source signals with remote receivers, calibration, operation, bandwidth reduction, high isolation, and reliable solar power or remote sites whereby the VNA module s may be used for characterization of a DUT as if they were incorporated into a single vector network analyzer chassis with access to a common clock.

Abstract: RF receivers having self-tuning capabilities. An example can provide self-tuning by detecting a first envelope of a first demodulated output signal and a second envelope of a second demodulated output signal. A difference between the detected envelopes can be filtered to generate a control signal. The control signal can be applied to a voltage-controlled crystal oscillator. In-phase and quadrature outputs of the voltage-controlled crystal oscillator can be used to demodulate a received signal to demodulate in-phase and quadrature signals. Loop gain dependency on input signal amplitude can be reduced by using logarithmic amplifiers after the envelope detectors, or by replacing the envelope detectors and logarithmic amplifiers with demodulating logarithmic amplifiers.

Abstract: Systems and methods for configuring and interconnecting VNA modules in daisy chains or via hubs are disclosed which overcome the constraints on the arrangement of the VNA modules in a system and the limitations on the flexibility and performance of the system present in the prior art. The VNA modules have ports which can be configured as input or output ports. In embodiments, configurable optical ports allow for long distance interconnection of VNA modules and hubs without loss of synchronization.

Abstract: A container and closure combination, for the containment of fluids and extraction therefrom by way of an extraction tube. The container comprises a closed volume with an opening configured to close the opening of the container; the closure is provided with an aperture such that the closure, upon fitment to the container opening, cannot be removed therefrom. The aperture of the closure comprises a unitary elastic unidirectional valve member that can operate in a first, closed condition, to prevent a flow of fluid from the container; and a second, operational condition, with an extraction tube sealingly engaged with respect to the valve, to permit an extraction of fluid from the container through the tube.

Abstract: In some implementations, a system for tracking orders in a supply chain includes one or more processors; and computer-readable memory storing instructions that, when executed by the processors, cause the processors to perform operations including receiving a request for an order metric for an order, wherein the order includes a plurality of items being distributed to a plurality of destination locations across a plurality of loads. The operations can further include identifying (i) inventory readiness dates for the items in the order and (ii) the loads transporting the items to their respective destination locations, wherein the inventory readiness dates specify predetermined first calendar dates on which the items are scheduled to be ready for distribution from the corresponding destination locations. The operations can further include outputting the order metric, wherein the order metric provides an aggregate view of the order's status across the plurality of loads transporting the items.

Abstract: An inventory readiness date is received that specifies a first calendar date on which an order of items should be ready at each items' respective destination location. For each item of the order, an arrival date before the readiness date is determined, the arrival date specifying a second calendar date on which the item should arrive at the item's respective destination location. A departure date before the arrival date is determined, the departure date specifying a third calendar date on which the item should depart the item's respective source location. For each item of the order, an inventory readiness metric is determined based on the item's travel based on tracking data for the item as the item travels from the item's respective source location to the respective destination location.

Abstract: Compositions and methods are provided to accelerate and improve wound repair and reconstruction of connective tissue structures, including tendons, by assembly of collagen using liquid crystalline collagen. The compositions and methods can be used to treat various forms of connective tissue injury or to prevent or slow degeneration to vulnerable tendons that are generally refractory to repair.

Abstract: The present invention relates to dispensing systems that include containers used to contain fluids that need to be dispensed in controlled quantities. In particular, the present invention relates to a dispensing system which can be readily and securely fastened to the walls and other operating surfaces associated with bathrooms, changing rooms, machine shops and the like. In water closets at places of work, hospitals, laboratories, workshops and similar places, there are many individuals who require access to liquids such as liquid soap, oils and production process chemicals etc. usually have a reservoir that must be filled from a larger supply container. The filling operation tends to be complicated and thus time-consuming and with the likelihood of the creation of a mess. It is often difficult to feed the product directly into the dispenser container by pouring the liquid from a big supply tank.

Abstract: A method for detecting objects comprising radiation-absorbent material includes transmitting signals of two different frequencies to a target location and receiving an intermodulation product from the target location. The signals are transmitted via separate antennas connected with respective transmitters. The intermodulation product is received by a receiving antenna connected with a receiver and arranged to receive the intermodulation product reradiated from the target location. The intermodulation product comprises a harmonic of the two signals.

Abstract: In accordance with an embodiment a device is usable to measure radio frequency (RF) signals including microwave signals to provide an alarm when a power level at its input exceeds predetermined levels. A user can attach the device to a coax cable on a microwave or wireless tower to determine if certain power levels are present and what levels are exceeded. If high power is indicated by the device, the user will then avoid attaching that coax cable to other measurement equipment which would be damaged by excessive RF power. The device is further usable, for example, to apply power to one coax cable in a cable bundle then identify which cable of the bundle is getting the power by connecting the device on the output end of each coax in the bundle, one by one.
