Abstract: Systems and methods for cold forming one or more features (106) in a flex circuit (100). The flex circuit (100) includes: an electronic circuit (102) connected to a substrate (104). When the substrate (104) is in a planar state, one or more areas deemed to be bent (or otherwise augmented) in the cold forming process, are additionally and selectively plated with an extra layer of metal (108), such as copper, so that only these one or more areas are now capable of being cold formed into shapes accurately.

Abstract: A system (116, 120) for electrically limiting leakage current in a patient-connected medical device (100). The system (116, 120) includes a first set (116) of one or more switching devices (118) that selectively connect a first power output (124) of a battery compartment (110) of the patient-connected medical device (100) with a first power input (126) of electronic components (102) of the patient-connected medical device (100) based on a first polarity of input voltage from the battery compartment (110). The system (116, 120) further includes a second set (120) of one or more switching devices (122) that selectively connect a second power output (128) of the battery compartment (110) of the patient-connected medical device (100) with a second power input (130) of the electronic components (102) based on a second polarity of the input voltage, wherein the first polarity is opposite the second polarity.

Abstract: A battery adapter (100) and method (800) of making the same. The battery adapter (100) includes a resilient tray (102) that defines a receiving area (104) for one or more batteries (106) and includes one or more resilient sidewalls (108) of a resilient material configured to be compressed by the batteries (106). The battery adapter (100) further includes a flexible circuit (132) wrapped around at least a portion of an exterior of the resilient tray (102) over the resilient sidewalls (108). The flexible circuit (132) includes a first set of one or more contacts (138) disposed on the exterior of the resilient tray (102) to deliver power to an associated device (150) and a second set of one or more contacts (136) electrically coupled with the first set of contacts (138). The second set of contacts (136) is disposed on an interior of the resilient sidewalls (108) in the battery receiving area (104).
