Abstract: Systems and methods for retractor interference avoidance is provided. At least one retractor includes a base and one or more elongate members extending from the base. The one or more elongate members are movable. A position of the at least one retractor may be determined and a trajectory of a surgical device may be received. At least one elongate member of the one or more elongate members positioned to interfere with movement of the device along a trajectory may be identified based on the position of the retractor and the trajectory of the surgical device.

Abstract: The present invention relates to a wearable smart device and system in the form of a smart bracelet configured to a geo-social mobile communication platform. This device combines self-expression of likes, interests, and social cues with a technological improvement over existing social networking through mobile devices. The smart bracelet contains a microcontroller, Bluetooth module, GPS module, one or more LED, and a battery. The device also includes user-selectable beads or “CODITTES” that attach to the bracelet and display various interests or social cues. The bracelet communicates with a mobile device through a front-end app and back-end app/database. The device facilitates physical social interactions by allowing users to share interests, social cues, and facilitate communication through near field communication. The present invention provides a novel solution to the challenge of in-person social interaction by combining self-expression and technology.

Abstract: The present invention refers to a process for production of a fastening system of interchangeable straps in sandals that includes the following steps: preparation of the base by creation of several apertures in its material; coating of said base with adhesive for attachment of the material composing the outer layer of the platform, to secure the sole and the insole; application of a fastener within said base, piercing the outer layer of the platform, by pressure on the support which is traversed by said fastener which is inserted inside the base and passes through multiple apertures and is fastened permanently; fastening of said fastener ensuring so that the support remains a reasonable distance from the platform to enable the straps to be engaged and disengaged.
