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: Spring-based sensor devices are described. For example, a spring-based sensor system may include at least one spring associated with a mechanical element, the at least one spring operative to change from a first state to a second state based on a configuration of the mechanical element, sensing circuitry configured to determine an electrical property of the at least one spring, the electrical property to have a first value when the at least one spring is in the first state and a second value when the at least one spring is in the second state, and a logic device to determine a status of the mechanical element based on the electrical property. Other embodiments are described.
