  • Publication number: 20230358546
    Abstract: A computer implemented method (400) of locating a plurality of mobile device trajectories (301) relative to each other and a map (1, 1?), the mobile device trajectories (301) comprising a time series of position nodes (303) joined by edges (305), the method (400) comprising: obtaining an input pose graph (311) comprising a plurality of mobile device trajectories (301) and a plurality of first constraints (309) defining the position and orientation of nodes (303) and edges (305) of the trajectories relative to each other; performing a non-linear optimisation process on the input pose graph (311) based on the first constraints (309), to reduce a cost function associated with the first constraints (309), the non-linear optimisation process providing a modified pose graph (313); extracting one or more sub-graphs from the modified pose graph (313), and for each sub-graph, individually processing the sub-graph to map match the nodes (303) and edges (305) of the sub-graph to features defined in the map (1,1?); and g

  • Publication number: 20220341752
    Abstract: A computer implemented method of aligning a plurality of map segments having a local reference frame to a reference map having a global reference frame, each map segment overlapping a portion of the area represented by the reference map, the method comprising: for each map segment, independently generating one or more candidate alignments, aligning the map segment to the reference map; for each candidate alignment evaluating a cost function representing the likelihood that the candidate alignment is correct; based on the candidate alignments and associated cost functions, generating one or more candidate solutions, each candidate solution comprising a single candidate alignment for each map segment; for each candidate solution, evaluating a cost function based on at least the cost functions for each candidate alignment included in the candidate solution; and based on evaluation of the cost functions, determining alignment of the plurality of map segments.

  • Publication number: 20120196133
    Abstract: A coated article includes a heat treatable (e.g., temperable) antireflection (AR) coating having four layers. The AR coating includes a layer adjacent the glass substrate having an index of refraction substantially matching that of the glass substrate, and having a compressive residual stress. In certain example embodiments, the coating may include the following layers from the glass substrate outwardly: stress-reducing layer/medium index layer/high index layer/low index layer. In certain example embodiments, depending on the chemical and optical properties of the high index layer and the substrate, the stress-reducing layer of the AR coating is selected to cause a net compressive residual stress and thus improve the overall performance of the antireflection coating when the coated article is heat treated.

  • Publication number: 20120060916
    Abstract: This invention relates to a front electrode/contact for use in an electronic device such as a photovoltaic device. In certain example embodiments, the front electrode of a photovoltaic device or the like includes a multilayer coating including at least one transparent conductive oxide (TCO) layer (e.g., of or including a material such as tin oxide, ITO, zinc oxide, or the like) and/or at least one conductive substantially metallic IR reflecting layer (e.g., based on silver, gold, or the like). In certain example instances, the multilayer front electrode coating may include one or more conductive metal(s) oxide layer(s) and/or one or more conductive substantially metallic IR reflecting layer(s) in order to provide for reduced visible light reflection, increased conductivity, cheaper manufacturability, and/or increased infrared (IR) reflection capability.

  • Patent number: 6178685
    Abstract: A fishing rod having an integrally formed receptacle for receiving a remote portion of the fishing rod, when the fishing rod is in a disassembled state. The receptacle is positioned adjacent the handle member of the rod, and is used to receive one end of a remote portion of a fishing rod. The remote portion of the rod is then secured in parallel relation with the base portion of the rod, to facilitate transport and storage. In an alternate embodiment, a detachable rod holder may be mounted onto the base portion of the fishing rod, to accomplish the same task. The detachable rod holder may be attached in one of several places, including attachment underneath the set screw that holds the rod and reel together, or it may be attached by sandwiching the attachment tab between the rod and reel. A stay clip may be used near an upper end of the base portion of the rod, to secure that end of the base portion to the outer end of the remote portion.
