摘要： Implementations described and claimed herein provide systems and methods for obstacle detection. In one implementation, a beam is transmitted at an elevation orientation from a transmit array system. The transmit array system includes transmit antenna arrays each having one or more transmit antennas. Target scatter is received at a receive array system including one or more receive channels. A virtual array is synthesized for the elevation orientation from an incidence of the target scatter on each of the one or more receive channels for each of the one or more transmit antennas. The virtual array has a size corresponding to the one or more transmit antenna arrays convolved with the receive array system. Four dimensional space information is generated from the virtual array, and any obstacles along a travel path are detected from the four dimensional space information.

摘要： The disclosed technology relates to a busbar and thermal cut-off device (TCO) sub-assembly. The sub-assembly may be configured to be connected to a first battery cell and a second battery cell. The sub-assembly may comprise a first busbar configured to electrically connect the first battery cell to the second battery cell when the sub-assembly is connected to the first battery cell and the second battery cell. The sub-assembly may comprise a first TCO connected directly to the first busbar. The sub-assembly may not extend above a top surface of the first battery cell when the sub-assembly is connected to the first battery cell.

摘要： Aspects of the present disclosure involve a radar system employing dual receive antenna arrays. The radar system may include a transmit antenna array to emit a radar beam toward a selected portion of a field of view, as well as a vertical receive antenna array and a horizontal receive antenna array. Each of the receive antenna arrays may include a plurality of antenna elements grouped into sub-arrays that may be configured to receive scatter signals from the selected portion, such as by way of beamforming. The received scatter signals may be combined within each sub-array to generate combined scatter signals, which may then be digitized. A signal data processor may then digitally process the digitized signals from the first sub-arrays and from the second sub-arrays, and correlate the digitally processed signals to generate detection information for each of a plurality of sub-portions of the selected portion.
