Abstract: Exemplary embodiments may terminate application of an electric pulse to a shape memory alloy (SMA) element that causes actuation of a medicament pump based on resistance values unlike conventional approaches that rely on a mechanical mechanisms to trigger termination of the application of the electric pulse. The magnitude of the resistance values, the rate of change (RoC) of the resistance values, the temperature of the SMA element, the time that has passed since initial application of the electric pulse to the SMA element, or combinations thereof may be used to trigger the termination of the application of the electric pulse to the SMA element in exemplary embodiments. The monitoring of the resistance of an unactuated SMA element may be used to determine when to initiate and when to terminate application of an electrical pulse to the other SMA element.

Abstract: Disclosed herein are drug delivery devices and methods for component positioning of a pump, such as a linear shuttle pump. In some approaches, a system may include first and second terminals movable with respect to one another, and a sensor device operable to detect a change in capacitance between the first and second terminals as the first and second terminals move with respect to one another. The sensor device may include a two-stage charger connected with a controller and a voltage source, the two-stage charger having a first capacitor connected with a first switch and a second capacitor connected with a second switch, the controller being operable to close the first switch to connect the first capacitor with the voltage source to charge the first capacitor, and open the first switch and close the second switch to connect the second capacitor with the voltage source to charge the second capacitor.

Abstract: A front suspension and stabilizing system for a snowmobile in which a pair of front steerable skis are connected to the vehicle body through a pair of suspension means which also are connected to a transversely extending torsion member attached to the vehicle body. The response of the torsion member to movement of the suspension means is stabilized and dampened by a resilient yieldable means such as a shock absorber connected to a mid portion of the torsion member through a forwardly extending arm fixed to the torsion member and connected at its other end to the shock absorber. A stabilizing system for a suspension system having a steering strut subject to axial and rotational movement, the steering strut being connected to a torsion member through a forwardly disposed link having universal connections to the strut and to the torsion member.
