Ces ports sont concus pour reduire le volume d'amorcage, car ils comportent une pluralite de compartiments hermetiques et/ou une ou plusieurs couches de base. Les ports peuvent egalement comprendre un revetement hydrophobe dispose sur une ou plusieurs de leurs surfaces.

L'appareil, dans un mode de realisation, comprend une base (105) et une premiere articulation rotoide (115) reliee a la base (105). L'appareil comprend egalement une structure de cardan incurvee (120) reliee a la premiere articulation rotoide (115). La premiere articulation rotoide (115) peut faire tourner la structure de cardan incurvee (120) autour d'un premier axe de rotation. L'appareil comprend une seconde articulation rotoide (125) reliee a la structure de cardan incurvee (120). L'appareil comprend une plateforme (135) reliee a la seconde articulation rotoide (125). La seconde articulation rotoide (125) peut faire tourner la plateforme (135) autour d'un second axe de rotation, et le second axe de rotation peut etre orthogonal au premier axe de rotation. De plus, un centre de gravite pour une combinaison de la structure de cardan incurvee (120) e...

Current robotic forceps often use traditional mechanisms with parts that are difficult to clean, wear quickly, and are challenging to fabricate due to their complexity and small size. The Oriceps design is based on the spherical kinematic configurations of several action origami models, and can be fabricated by cutting and folding flat material. This design concept has potential implementation as surgical forceps because it would require fewer parts, be easier to sterilize, and be potentially suitable for both macro and micro scales. The folded and planar characteristics of this design could be amenable to application of smart materials resulting in smaller scale, greater tool flexibility, integrated actuation, and an adaptability to a variety of tool fun...

Since 2007, a two-semester Global Engineering Outreach course at Brigham University has enabled engineering and technology students from multiple disciplines to design and implement humanitarian-based engineering projects. Energy, water, sanitation, and health projects have been implemented in Tonga, Ghana, and Peru. Currently, the projects focus on the needs of communities in Peru. Typically, nearly half of the students in the two-semester course speak and write Spanish fluently and have lived abroad in a Spanish-speaking country. This allows students to regularly engage with their Peruvian counterparts during the two semesters via phone and email exchanges on a near-weekly basis. An important aspect of the regular contact is the need to establish relationships and to obtain feedback and input from the community regarding the project. This work presents an overview of product development in relationship to the effectiveness of community engagement between the student development team and the Peruvian counterparts. In addition, strategies to foster community engagement will be discussed. Such strategies include workshops, resource development and investigation, design constraints and reviews, in-country communication, and an implementation trip.

The barrier crease pattern was employed using the membrane-fold technique for surrogate folds and to assist in thickness accommodation. A proof-of-concept barrier was fabricated and tested, demonstrating ballistic resistance, a large deployment ratio, and rapid deployment times.
