Abstract: A method for estimating a position of a moving object comprises receiving one or more ranging measurements for distances between an object and one or more anchor points from a ranging device, receiving sensing data from one or more sensors, determining a distance and a heading direction of the object relative to a position of the one or more anchor points based on the one or more ranging measurements and the sensing data, applying a mapping using the distance and the heading direction of the object to correct the ranging measurements, and determining a position of the object based on the corrected ranging measurements.

Abstract: A method for estimating a position of a moving object comprises: storing one or more reference position estimates for the moving object in a first buffer; storing step information in a second buffer, the step information including one or more step sizes and one or more step headings; receiving a motion event signal indicating the moving object moves continuously with a bounded direction; correcting the step information based on the one or more reference position estimates in response to receiving the motion event signal; and estimating the position of the moving object using the corrected step information.

Abstract: A method includes, when a handheld device is in motion within a service area to be traversed by a robot: obtaining ultra-wideband (UWB) ranging measurements between the handheld device and multiple anchors located in the service area; and obtaining image data and inertial measurement unit (IMU) data. The method also includes determining a trajectory of motion of the handheld device based on the UWB ranging measurements. The method also includes adjusting the trajectory based on image features obtained from the image data and motion estimates obtained from the IMU data. The method also includes identifying the adjusted trajectory as a boundary of the service area.

Abstract: An electronic device includes a Lidar sensor, a radar sensor, and a processor. The processor is configured to identify one or more objects from Lidar scans. The processor is configured to transmit, via the radar sensor, radar signals for object detection based on reflections of the radar signals received by the radar sensor. While the electronic device travels the area, the processor is configured to generate a first map indicating one or more objects within an area based on the Lidar scans and a second map based on the radar signals. The processor is configured to determine whether the second map indicates a missed object at the portion of the first map that is unoccupied. In response to a determination that the second map indicates the missed object, the processor is configured to modify the first map with the missed object.

Abstract: A method, an electronic device, and computer readable medium are provided. The method includes receiving an input into a neural network that includes a kernel. The method also includes generating, during a convolution operation of the neural network, multiple panel matrices based on different portions of the input. The method additionally includes successively combining each of the multiple panel matrices with the kernel to generate an output. Generating the multiple panel matrices can include mapping elements within a moving window of the input onto columns of an indexing matrix, where a size of the window corresponds to the size of the kernel.

Abstract: A method includes receiving at least one wireless signal measurement and motion sensor measurements. The method also includes generating a location estimate based on the at least one wireless signal measurement. The method also includes determining whether a step is present based on the motion sensor measurements. The method also includes, in response to determining that a step is present, determining a step heading offset based on the location estimate and the motion sensor measurements, and determining a step length and heading based on the motion sensor measurements and the step heading offset. The method also includes determining a location of an object based on at least one of (i) the at least one wireless signal measurement or (ii) the step length and heading.

Abstract: A method includes obtaining wireless fidelity (Wi-Fi) based channel state information (CSI). The method also includes filtering the CSI to remove radio frequency (RF) interference. The method further includes executing a motion detection module that detects for motion in a space based on whether macro-movements are present in the filtered CSI, and provides an indication that the space is occupied upon detecting motion in the space. The method also includes, in response to the indication that the space is occupied, executing an occupancy detection module that detects whether the space is still occupied based on whether micro-movements and breath signals are present in the filtered CSI, retains the indication that the space is occupied upon detecting that the space is still occupied, and provides an indication that the space is not occupied upon detecting that the space is no longer occupied.
