摘要： A vehicle is described herein that includes a body structure such as a windshield and/or a windshield frame, a compartment such as a passenger compartment, one or more body panels around the compartment, and an at least partially floating cover, such as a roof, disposed over the compartment. The floating cover includes one or more body structure mounts and an overhang extending from the body structure over the compartment to an aft portion of the compartment. Other similar embodiments include features such as support structures, support structure mounts that mount the floating cover to the support structures, and various aerodynamic features incorporated into the floating cover. For example, some embodiments include roll bars and roll bar mounts, aerodynamic arcs, and aerodynamically continuous surfaces.

摘要： A three-wheeled vehicle crumple zone is described. The crumple zone includes a triangular, single-sided swing arm coupling a wheel to a frame of the vehicle at an end-most portion of the vehicle. The swing arm includes a u-shaped frame yoke coupling the swing arm to the frame and an angled wheel yoke coupling the wheel to the swing arm. The wheel yoke extends from the frame yoke at an angle ranging from 40 to 70 degrees, such that the frame yoke, the wheel yoke, and a centerline axis extending perpendicularly from the frame yoke form a right triangle.

摘要： Methods for negotiating optimum parameters for communicating between a wireless control device and a wireless user device are disclosed. The methods generally include transmitting a frequency-hopped and spread negotiation signal using network-maximum parameters. The initial parameters make the negotiation signal long-range but low-data. The methods further include adjusting the initial parameters to optimal parameters based on a link budget and data rate requirements received in response to the negotiation signal. The signals are communicated on the 902-928 MHz unlicensed ISM band, and the parameters include spreading factor, output power, and carrier frequency channel bandwidth.

摘要： A method of powering an intermittent-duty cycle winch is disclosed. The method includes identifying a number of amp-hours required to power the winch through one duty cycle, identifying a minimum required rest period between two consecutive duty cycles, and assembling a power supply unit that powers the winch based, at least in part, on the duty cycle and the rest period. The duty cycle is mechanically or thermally limited. The power supply unit includes at least two components: a power storage unit and a charging unit that recharges the power storage unit during the rest periods. The power storage unit powers the winch through at least one duty cycle. The charging unit recharges the power storage unit during the rest period so that the power storage can power the winch through at least a second duty cycle that immediately follows the end of the minimum required rest period.

摘要： A vehicle winch mechanism includes a drum, a motor and transmission, at least one drum and motor side support, at least one battery, and a motive trickle charge mechanism. The drum pays out and takes in a line. The motor and transmission drive the drum. The side supports couple the drum, the motor, or both to the vehicle. The battery provides power to the motor. The motive trickle charge mechanism charges the battery. In one embodiment, the motive trickle charge mechanism includes a permanent magnet, an enclosure housing the magnet, and two or more sets of conductive coils wrapped around the enclosure and electrically coupled to the battery. The enclosure houses the magnet such that the magnet freely moves and changes orientation within the enclosure. The coils of an individual set of coils are aligned along parallel planes, and the coils of separate sets are aligned along intersecting planes.

摘要： A redundant star network is disclosed. The network includes a peripheral device (PD), a control hub, and a backup hub. The control hub and backup hub each have a wireless long range transceiver, hardware processors, and hardware memory. The PD includes a wireless long range transceiver and a microcontroller. The control hub and backup hub hardware memories store system operation information. The system operation information includes instructions for controlling the PD. The PD microcontroller includes test firmware and update firmware. The test firmware instructs the PD to test the control hub and to listen for a test response signal indicating the control hub is operational. The PD update firmware instructs the PD to switch control of the PD to the backup hub when the test response signal is not received within an expected response timeframe after the test signal is sent.

摘要： A dual modulation network is disclosed. The dual modulation network includes a primary network hub (PNH) having a PNH Long range transceiver and a PNH microcontroller. The PNH microcontroller has communication firmware for long range spread spectrum (SS) and narrowband frequency shift keying (FSK) signal communication via the PNH Long range transceiver, and includes a PNH clock signal. The dual modulation network also includes a peripheral device (PD). The PD includes an actuation mechanism, a PD Long range transceiver, and a PD microcontroller. The PD microcontroller has actuation firmware, communication firmware for communication via the PD Long range transceiver, and location firmware, and includes a clock signal. The location firmware instructs the PD long range transceiver to transmit a location signal encoded with a PD transmit time stamp notifying a receiving device of the time the PD transmitted the location signal.

摘要： A system for a redundant star network is disclosed. The system consists of a control hub, one or more backup hubs, and at least one peripheral device (PD), the peripheral device comprising a housing having at least one selectable side transparent or opaque to radio frequency (RF) transmissions while the remaining sides are opaque to RF transmissions. The control hub controls the PD, for example by controlling how the PD operates under certain conditions. The PD includes a long-range, wireless transceiver and a microcontroller, which includes instructions for periodically testing, via test signals, whether the control hub is functional. In the case that the control hub does not respond to the test signals, the PD includes instructions for switching control of the PD to the backup hub, which also stores control instructions for the PD, similar to the control hub.
