Abstract: An automated belt-based diverter system is described in some implementations. In an example implementation, the system may include a belt, which includes a closed loop of material, coupled with a pulley and a motor that provides motive force to the belt, for example, using the pulley. In some implementations, one or more diverter arms may be coupled with the belt. A diverter arm may include a body with a first arm end, a second arm end, and a pushing surface. A diverter arm may be coupled at the first end with the belt so that the second end extends away from the belt and the pushing surface may contact an object to push the item. The system may also include a controller coupled with the motor to rotate the belt in defined directions or distances based on instructions.

Abstract: Described herein are battery modules and methods of fabricating thereof. In some examples, a battery module comprises an enclosure, separated into two enclosure portions and a thermal portion, positioned between the two enclosure portions. Two enclosure portions are in part defined by side walls, which can be tapered. The thermal portion comprises two thermal walls, which are operable as the bottoms of the two enclosure portions and form a thermal cavity between these thermal walls. In some examples, the enclosure is a monolithically cast component. Alternatively, the enclosure can be partially cast with one thermal wall welded thereafter to a cast subassembly. The battery module also comprises two sets of batteries, each positioned into a corresponding enclosure portion. Each battery set is interconnected with an interconnecting assembly, positioned between the battery set and the corresponding cover, for this enclosure portion.

Abstract: Described herein are battery packs and electric vehicles using these packs. In some examples, a battery pack comprises two portions/covers and a set of battery modules positioned within the enclosed cavity formed by these portions. A battery pack may comprise a set of pressure-relief valves positioned in and protruding through a wall of at least one portion. Each valve can be coaxial with a corresponding gap provided between two adjacent modules. The valve is configured to provide a fluid path (to the exterior of the battery pack) when the pressure inside the pack exceeds a set threshold. In some examples, the battery pack comprises an inlet tube fluidically coupled to the inlet port of each module and an outlet tube fluidically coupled to the outlet port of each module. A set of specially configured orifices or controllable valves is positioned on the fluid path through each module.

Abstract: An automated sorting and packing system is described. In an example implementation, the system may include a transfer station that transfers an item into a shipping carton, one or more conveyors that convey the item and/or carton to a transfer station, a scanner that scans the item, and a processor communicatively coupled with the scanner and the one or more conveyors. According to some implementations, the system may perform operations including determining a carton identifier associated with a carton based on an order, assigning a transfer station to the order and the carton identifier based on scan data identifying an item, transporting the item to the transfer station using a conveyor, and transferring the item from the conveyor to a carton associated with the carton identifier using the transfer station.

Abstract: A method for wirelessly synchronizing a radar detector to a radar transmitter includes wirelessly receiving a first instance of a frequency-modulated continuous-wave (FMCW) radar signal directly emitted by the radar transmitter, determining a frequency slope change event in the FMCW radar signal using the first instance of the FMCW radar signal and temporally synchronizing the radar detector to the radar transmitter based on the frequency slope change event. Determining the frequency slope change event may include generating a frequency slope monitoring signal. In some embodiments, generating the frequency slope monitoring signal comprises mixing the first instance of the FMCW radar signal with a second instance of the FMCW radar signal. The second instance of the FMCW radar signal may be a reflected instance or a locally delayed instance of the first instance. A corresponding apparatus, computer readable medium and system are also disclosed herein.

Abstract: A method for determining location information for an airborne target includes synthesizing a cyclic transmit signal, transmitting an electromagnetic beam corresponding to the cyclic transmit signal, providing a plurality of vertically offset return signals corresponding to at least two receive antennas that are vertically offset, down-converting the plurality of vertically offset return signals with the cyclic transmit signal to provide a corresponding plurality of baseband signals, determining magnitude and phase information for each vertically offset return signal as a function of range from the corresponding baseband signal, and determining elevation information for an airborne target from the magnitude and phase information. Azimuthal information for the airborne target may be determined by tracking amplitude variations in the return signal in response to azimuthal rotation of the receive antennas. A corresponding apparatus, system, and computer readable medium are also disclosed herein.

Abstract: The fish descaling tool is adapted for use with a fish. Specifically, the fish descaling tool is a hand held device that is designed to remove scales from fish. The fish descaling tool is an electrically powered device that rotates a scaling cylinder in such a manner that the scaling cylinder will remove the scales of the fish without damaging the underlying flesh of the fish. The fish descaling tool comprises a scaling cylinder, a hood, a handle, a motor, and a power source.

Abstract: An interferometric switched beam radar apparatus and method are disclosed. In one embodiment, a selected antenna of a planar array of beam forming antennas is activated with a substantially continuous frequency modulated transmit signal and a return signal is received from at least two return antennas that have a known offset distance relative to each other. Phase information is extracted from each return signal and used to present information regarding an operating environment to a user. Each beam forming antenna within the array may correspond to a particular viewing angle within the operating environment.
