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: In an exemplary embodiment, a drug delivery device is configured for Body Channel Communication (BCC). The drug delivery device may include a conductive element embedded in an adhesive patch that secures the drug delivery device to the user. This conductive element acts as a coupler to the body of the user. Another conductive element may also be provided at a face of the housing. This conductive element acts as the other end of the coupler formed with the conductive coil in the adhesive patch. The conductive coil in the adhesive patch conforms well to the user's skin surface and thus facilitates a good quality coupling with the user.

Abstract: Exemplary embodiments may provide an adhesive pad that is designed to be used with an on-body medical device. The adhesive pad may partially or fully surround a perimeter of the on-body medical device. The adhesive pad may be the primary mechanism or may provide an additional mechanism for helping to secure the on-body medical device to the user. In addition, the adhesive pad may include a metallic coil, such as a metal loop, that is woven into the adhesive pad or otherwise inserted into or secured to the adhesive pad. The metallic coil may play multiple roles. First, the metallic coil may act as an antenna to facilitate wireless communications with the on-body medical device, such as NFC communications. In addition, the metallic coil may serve as a power source for electric components positioned on the adhesive pad.

Abstract: One or more button cell batteries may be used in an on-body medical device like a drug delivery device to act as an antenna for wireless communications. Since the one or more batteries are already present in the on-body medical device, no additional real estate on the printed circuit board is required for the antenna. In some exemplary embodiments, a single button cell battery is used as an antenna, and in other embodiments, multiple button cell batteries are used as the antenna. For example, a single button cell battery may be used as part of a monopole antenna. Multiple button cell batteries may be used as part of a dipole antenna.

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.

Abstract: An on-body drug delivery device may have one or more antennas secured outside a housing of the on-body drug delivery device for facilitating wireless communications. The one or more antennas may be secured to an adhesive pad that adheres the on-body drug delivery device to a user. Alternatively, the one or more antennas may be secured to a portion of the housing for the on-body drug delivery device. In such instances, the one or more antennas may pass through one or more holes in the housing to facilitate an electrical connection with a component, like a wireless communications transceiver, inside the housing. Alternatively, wireless communications with the one or more antennas and the component may be used.
