Abstract: A method of digital assessment of chemical dip tests is disclosed. A photograph of a dip tester including a colour change pad is taken with a mobile device, for example a mobile phone. The dip tester is photographed on or alongside a reference card, with both the dip tester and the reference card in the same frame. A processor on the mobile device analyses the photograph thus obtained to determine a value for a characteristic of water being tested. The characteristic may be for example, pH, concentration of iron, concentration of copper. The water may be central heating system water.

Abstract: In one embodiment, a method for determining a dynamic head-related transfer function for a subject includes receiving audio recordings of a sound captured by audio sensors. The sound is emitted by an in-ear speaker worn by the subject. Additionally, a reference signal captured by a microphone coupled to the in-ear speaker and one or more images captured by image sensors are received. The one or more images depict a body pose of the subject while the sound is emitted by the in-ear speaker and may be used to generate a pose representation of the body pose of the subject. A head-related transfer function for each audio sensor is determined based on the pose representation, the audio recordings of the sound, and the reference signal. The dynamic head-related transfer function is determined based on the head-related transfer function for each audio sensor.

Abstract: In one embodiment, a method for emitting a sound from an in-ear speaker worn by a subject includes generating, by an audio source of the in-ear speaker, a source audio signal. One or more speakers of the in-ear speaker may emit a sound based on the audio signal and an audio-transport tube of the in-ear speaker may receive the sound. The one or more speakers may be comprised of a singular speaker or a speaker array coupled to a crossover network. The audio-transport tube has an input end coupled to the one or more speakers to receive the sound. An audio reflector of the in-ear speaker may reflect the sound. The audio reflector is coupled to an output end of the audio-transport tube.

Abstract: A computer implemented method includes receiving a document with line item textual entries and an attachment containing images of different objects characterizing different transactions. The images of the different objects are split into individual image objects. Attributes from the individual image objects are extracted. The line item textual entries are matched with the individual image objects to form matched image objects. The matched image objects include ambiguous matches with multiple individual image objects assigned to a single line item textual entry or a single individual image object assigned to multiple line item textual entries. An assignment model is applied to resolve the ambiguous matches. The assignment model defines priority constraints, assigns pairs of line item textual entries and individual image objects that meet highest priority constraints, removes highest priority constraints when ambiguous matches remain, and repeats these operations until no ambiguous matches remain.

Abstract: A computer-implemented method includes receiving, by a programmable logic controller coupled to a control unit associated with a vessel containing oil and water within a Gas-Oil-Separation Plant (GOSP), a first signal representing a first capacitance measurement detected by a first capacitance probe attached to the vessel at a first elevation. Determining whether an alarm condition is met by detecting whether the first capacitance measurement is higher than a first predetermined maximum limit, or a rate of change (ROC) of the first capacitance measurement is higher than a first predetermined ROC limit, or both. If the alarm condition is met, sending an alarm signal indicating that an upcoming process upset has been detected within the vessel. Subsequent alarms at higher elevations, if available, can alarm operators if the emulsion layer thickness continues to increase and further mitigation measures are required (such as higher demulsifier dosage, skimming of emulsion layer, etc.).

Abstract: The invention relates to constructs comprising a transmembrane protein pore subunit and a nucleic acid handling enzyme. The pore subunit is covalently attached to the enzyme such that both the subunit and enzyme retain their activity. The constructs can be used to generate transmembrane protein pores having a nucleic acid handling enzyme attached thereto. Such pores are particularly useful for sequencing nucleic acids. The enzyme handles the nucleic acid in such a way that the pore can detect its component nucleotides by stochastic sensing.
