A method of controlling an exoskeleton mobility device includes executing a control application with an electronic controller to perform: sensing at least one of an angular position or angular velocity of a stance/trailing leg during a single support dynamic state of a gait cycle; determining whether the angular position satisfies an advanced gait threshold; and when it is determined that the angular position satisfies the advanced gait threshold, the control system employs advanced gait control in which a duration of double support states between single support dynamic states is minimized. For advanced gait control the control system controls such that hip joint component velocities are non-zero during transitions from swing states to stance states, and knee joint component velocities are non-zero during transitions from stance states to swing states of the gait cycle. Each step of the gait cycle thus blends into a next step by way of hip joint component swing-to-stance extension, and/or knee joint component stance-to-swing flexion.

A device and a method of monitoring a machine. The method includes interfacing an edge device with the machine and detecting a condition of the machine with the edge device. The method identifies the condition with the edge device and sends a signal identifying the condition to a program running on the machine. The signal of the edge device communicates with the program through a register of recorded values and the edge device checks the register and notifies the program by altering a value in the recorded values of the register to a signal value. The program reads the recorded values in the register and initiates an action in the machine when the signal value is present in the recorded values of the register.

In accordance with one embodiment, a fan controller operates in a standard mode when main power is provided to the power supply unit in which speed of the fan is controlled in response to a primary pulse width modulation (PWM) signal from a power controller. A loss of the main power to the power supply unit may be detected at a logic circuit, which provides a secondary PWM signal to the fan controller in response to the loss of the main power. In certain embodiments, the fan controller is operated in a power loss mode in response to the secondary PWM signal to direct the speed of the fan to a low-power consumption target speed.
