Abstract: A blower system includes a blower including an electronic control unit configured to control operation of the blower, a duct holder couplable to the blower and including a flexible duct, the flexible duct configured to extend from and direct an airflow generated by the blower, and one or more of a cooler module, a sensor module, and a filter module, wherein: the cooler module, when coupled to the blower and electrically coupled to the electronic control unit, is configured to cool the airflow generated by the blower, the sensor module, when coupled to the blower and electrically coupled to the electronic control unit, is configured to sense a condition of the airflow generated by the blower, and the filter module, when coupled to the blower, is configured to reduce an amount of a particulate in the airflow generated by the blower.

Abstract: A cable puller has a frame, a capstan rotatably mounted on the frame, a motor which drives the capstan to rotate, a power supply which supplies electrical current to the motor, a transmission which transfers torque from the motor to the capstan, a display mounted to the frame, a sensor operable to generate a signal, and a controller. The transmission can operate in a low-speed configuration and a high-speed configuration. The controller is electrically coupled to the motor, the power supply, and the display. The controller includes computer executable instructions stored in a computer readable medium for controlling operation of the cable puller to receive the signal from the sensor, determine a torque of the capstan based on the signal, determine a tension of a cable being pulled based on the torque of the capstan, and generate a control signal when the tension of the cable approaches a predetermined tension.
