  • High efficiency treadmill motor control
    Patent number: 10207145
    Abstract: A high voltage direct current signal is obtained from a power supply. The power supply includes power factor correction circuitry. A control command is obtained from an exercise machine. The exercise machine includes a direct current motor. A pulse-width modulation signal is generated from the direct current signal based on the control command. The pulse-width modulation signal is provided to the direct current motor.

  • Support device for a rib
    Patent number: 7490440
    Abstract: A support device (8) for a rib (14) between a floor (18) and a roof (16). The device includes an expansion means (10) and a pair of resilient members (12a, 12b). Each of the resilient members (12a, 12b) have a proximal end (27a, 27b) adapted for connection to the expansion mean (10) and a distal end (28a, 28b) curved away from the expansion means (10) and adapted for engagement with the floor (18) and roof (16) respectively. When the device (8) is positioned towards or against the rib (16) and the expansion means (10) is activated to drive the members (12a, 12b) apart, the member's distal ends (28a, 28b) are driven substantially vertically into engagement with the floor (18) and the roof (16) and a portion of the device (8) is driven substantially laterally (32) into abutment against the rib (14).
