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: 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.
