  • Patent number: 10830906
    Abstract: A method of adaptive weighting adjustment positioning has the following steps: performing an initialization procedure, determining whether a first feature point is detected; when the first feature point is detected, based on multiple positioning methods, multiple positioning information will be generated, and multiple weightings will be set, and then based on the weightings and the positioning information, calculating the positioning information output; by way of adaptive weighting adjustment among the multiple positioning methods, the multiple positioning methods can be integrated. In this way, even if one of the positioning methods is temporarily unavailable, the positioning information can still be calculated by weighting adjustment between the positioning information of the remaining two available methods, and that allows users to continue to obtain accurate positioning information to confirm the current location.

  • Patent number: 10702610
    Abstract: Polythioaminal polymers are made from hexahydrotriazine precursors and dithiol precursors. The precursors are blended together and subjected to mild heating to make the polymers. The polymers have the general structure wherein each R1 is independently an organic or hetero-organic group, each R2 is independently a substituent having molecular weight no more than about 120 Daltons, X and Z are each a sulfur-bonded species, at least one of X and Z is not hydrogen, and n is an integer greater than or equal to 1. X and Z may be hydrogen or a functional group, such as a thiol-reactive group. The reactive thiol groups of the polythioaminal may be used to attach thiol-reactive end capping species. By using water soluble or water degradable dithiols, such as polyether dithiols, water soluble polythioaminals may be made. Some such polymers may be used to deliver therapeutics with non-toxic aqueous degradation products.
