Abstract: Systems and techniques for generation, storage, and updating of common floor plans across shared autonomous mobile devices. The systems and techniques include extraction of semantically meaningful data from one or more occupancy maps to provide a floorplan to a user that aligns with the user's understanding of the space using heuristics and machine learning techniques. The techniques also enable repair of damaged or inconsistent floor plan geometries through the use of polygon triangulation and graph cuts.

Abstract: The disclosed computer-implemented method relating to read-only memory can include (i) asserting a column select signal to select a particular column within a column mux read-only memory, (ii) forwarding, in response to asserting the column select signal, a bit value stored at that particular column to a gate of a transistor that connects a first stage local bitline to a second stage local bitline, and (iii) forwarding an inversion of the bit value to the second stage local bitline through the drain of the transistor for local bitline sensing. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A system 10 to optimize a light emitting diode (LED) power allocation framework within a room is disclosed. The system 10 includes a data receiving subsystem 20, configured to receive parameters corresponding to light emitting diodes (LED), visible light communication (VLC) transmitters and visible light communication (VLC) receivers. The system 10 includes a blockage generalization subsystem 22, configured to identify location and height of one or more detected blockages within the room from the received parameters. The system 10 includes an optimal power allocation subsystem 24, configured to compute a visible light communication (VLC) channel gain for each of the one or more light emitting diodes (LED) with reference to identified location and identified height and configured to optimize the power allocation framework to achieve maximized visible light communication (VLC) data rate based on the computed visible light communication (VLC) channel gain and one or more constraints.

Abstract: Systems and techniques for updating floor plans for use by autonomous mobile devices. The techniques include accessing a first floor plan with associated spatial metadata. An updated occupancy map is received with additional geographic updates over the first floor plan. A transformation of the first floor plan is determined to match the new occupancy map. The spatial data and the first floor plan are transformed and the transformed spatial metadata is associated with the new occupancy map to form a second floor plan.
