Abstract: Implementations relate to a master control device. In some implementations, a master control device includes a thumb grip member including a thumb grip receptive to a thumb of a hand of a user. The master control device includes a finger grip member coupled to the thumb grip member at a proximal end of the master control device and extending toward a distal end of the master control device, where the finger grip member includes a finger grip receptive to multiple fingers of the hand. The thumb grip member and finger grip member are movable in a pinching configuration with respect to each other. The master control device includes a sensor coupled to at least one of the thumb grip member or finger grip member to sense relative positions of the thumb grip member and finger grip member with respect to each other in the pinching configuration.

Abstract: A system and method of manufacture of a foldable electrical connector-housing system includes: a first end panel with an outer first end panel side having first end panel contacts; a second end panel having an outer second end panel side; a clip mechanism in at least one of the two end panels for attaching the foldable electrical connector-housing system to a flat surface; a fold mechanism is connected between the first end panel and the second end panel for folding into a folded configuration; and an electronic unit on the first end panel, the electronic unit coupled to the first end panel contacts.
