Abstract: A portable winch includes a motor, a rotatable drum, and a clutch assembly configured to engage a gear assembly. In a default state, the motor is mechanically detached from the rotatable drum, and, in response to activation of the portable winch, the clutch assembly automatically engages the gear assembly, thereby mechanically attaching the motor to the rotatable drum.

Abstract: A modular vehicle gauge system includes a remote unit, a sensor module and at least one gauge. The remote unit includes a first microcontroller, a memory and an interface to allow communications with the sensor module and the at least one gauge. The sensor module includes a second microcontroller, and an interface to allow communications with the remote unit and the at least one gauge. The at least one gauge includes a third microcontroller, an interface to allow communications with the remote unit, and means for changing an illumination of the at least one gauge upon the occurrence of an event. The modular vehicle gauge system also includes means for exchanging information between the remote unit, the sensor module and the at least one gauge.
