Abstract: The invention is an improved colonoscopy system and method. The disclosed system includes the use of a tiny, wired capsule that can be magnetically controlled through the upper and/or lower GI tract of a patient. The capsule includes a camera assembly and a light assembly to allow a medical professional to visualize an interior cavity of the patient. The capsule further includes one or more internal magnets. The capsule is configured with an outer covering that protects the internal components from damage during use. An external magnet is also provided to drive and orient the capsule through the patient's body via magnetic attraction with the internal magnet.

Abstract: The present invention relates to a low-profile splice protection system for protecting multi-fibre fusion splice sites. The splice protection system comprises coating material to package the splice site and may comprise a protective housing.

Abstract: An air control mechanism and a sphygmomanometer including the air control mechanism are provided. The air control mechanism includes a first housing, a second housing, a tower-shaped piston, and an intake-exhaust mechanism. In an intake state, air in the first chamber sequentially flows through the flow groove, presses against the elastic thin plate, flows through the stepped hole and flows to the exhaust passage through the guiding groove. In an exhaust state, air sequentially flows through the flow passage and the exhaust passage to the guiding groove.

Abstract: Provided is the use of two-dimensional nanomaterials in the inhibition of a coronavirus, and specifically disclosed is the use of the two-dimensional nanomaterials in the preparation of a medicament for treating or preventing diseases caused by a coronavirus or of a material for adhering to or inhibiting the coronavirus. The two-dimensional nanomaterial is selected from the group consisting of copper indium thiophosphate (CIPS) nanosheet, graphene oxide nanosheet, molybdenum disulfide nanosheet, black phosphorus nanosheet and mixtures thereof. The coronavirus is selected from one of HCoV-229E, HCoV-OC43, HCoV-NL63, HCoV-HKU1, SARS-CoV, SARS-CoV2 or MERS-CoV. The diseases caused by the coronavirus are diseases caused by coronavirus infection. The material has the advantages of being simple to prepare, having a high biological safety and an excellent effect.

Abstract: An approach is provided for providing a map matcher tolerant to wrong map features. The approach involves, for instance, finding a segment of a probe trajectory containing a plurality of low-speed probe points. The approach also involves forming a line between a first and a last probe point of the segment. The approach further involves calculating a distance from each probe point of the segment to the line. The approach further involves splitting the segment based on comparing the distance to a threshold at a turning point of the segment. The approach further involves creating a new probe trajectory based on a plurality of high-speed probe points in the probe trajectory and the turning point. The approach further involves estimating a heading of the turning point of the segment based on the new trajectory, and then performing a feasibility check between two consecutive probe points of the new trajectory.

Abstract: Pandemic COVID 19 causes global crisis in human health and economy. The pathogen of COVID 19, like the Influenzas causing common flus, belongs to a common type of virus called Ribonucleic Acid (RNA) virus. RNA viruses are composed of three structural components: genomic RNA, envelop and nuclear proteins, and bilayer lipid membrane. Targeting COVID 19 and all RNA viruses, the present invention describes an effective disinfectant system, which applies the combination of RNases, proteases, and detergents, at a broad range of concentration, pH, and temperature in the utilization, to eliminate the RNA viruses from any contaminated surfaces, airways, and filters. The disinfectant system provides an effective, convenient, environment friendly, and safe solution, for commercial and customer use, to disinfect RNA virus pathogens in concern.

Abstract: A photonic integrated circuit chip includes a substrate and a wafer on the substrate. The wafer itself includes a photonic grating coupler with a taper portion and grating features. The grating features extend from the taper portion toward the substrate.

Abstract: An optical transceiver may include an optical transmitter and an optical receiver. The optical transmitter and receiver may each include a grid including one or more lanes spaced apart. Each lane may correspond to a predetermined optical signal, or wavelength. The optical transmitter may include one or more sets of lasers to output one or more optical signals corresponding to the grid. Each set of laser may output a set of optical signals. Each set of lasers and, therefore, each set of optical signals may have a different passband. For example, the multiplexing and/or demultiplexing architecture may have a wide passband for the first set of optical signals and a narrow passband for the second set of optical signals. The narrow passband may be determined based on the space between two wider passbands.
