Abstract: An actuation mechanism for a surgical instrument (100) includes a sleeve (202) configured to receive the surgical instrument and including one or more parts (208, 210, 226), with studs (250, 252) provided on each part, on some parts only, or distributed over the different parts. At least two wheels (204, 206) are mounted on the sleeve on either side of the part or parts, each wheel being equipped with at least one groove (242) and a mechanical transmission element (244). The groove of each wheel movably receives one of the studs in the groove. At least two drive shafts (212, 214), each being equipped with a first mechanical transmission element (254), cooperate with the mechanical transmission element (244) of one of the wheels.

Abstract: A control interface (I) for a robotic system for the vitreoretinal surgery includes a haptic device (1) equipped with an articulated chain (2) having a free end (3). The interface includes a guiding device (10). The guiding device (10) includes a stationary surface (11), a guiding (20) mounted on the stationary surface by a ball joint (21), and a rod (30) mounted on the guide (20) by a sliding connection (25) with an axis corresponding to that of the rod (30). The rod includes a first end (32) mounted stationary on the free end (3) of the haptic device (1) and a second end (33) on which a gripping member (5) is mountable.

Abstract: The present disclosure is directed to wheel-based human-powered spinning system comprising: a chassis configured to secure a user; a track surrounding said chassis; and at least one omni wheels attached to said chassis, wherein said chassis spins with unlimited range of motion, along pitch, yaw and roll axes, inside the track while supported by said at least one omni wheels, said track being independent of contact from said chassis.

Abstract: A system for monitoring a position of a pipe joint as the pipe joint moves through a production system along a longitudinal axis of a wellbore of the production system includes an ultrasonic sensor configured to detect the pipe joint. The system also includes a controller configured to receive a signal from the ultrasonic sensor. The controller includes a processor configured to determine a first position of the pipe joint along the longitudinal axis at a first time based on the signal. The processor is further configured to determine a displacement from the first position of the pipe joint, and to determine a second position of the pipe joint along the longitudinal axis at a second time based on the displacement. The controller also includes a memory configured to store the first position and the second position.

Abstract: The present invention is directed to a diagnostic method for non-alcoholic fatty liver disease (NAFLD) and to a method for monitoring the progression of the disease based on the determination of the levels of different metabolites. The invention also provides a method for determining the efficacy of an NAFLD therapy and a method for identification of compounds suitable for the treatment of NAFLD.

Abstract: An early kick detection system including a kick detection computing device coupled to at least one sensor associated with a drilling system of a well. The kick detection computing device is configured to receive measurement data from the at least one sensor. The measurement data includes one or more kick indicators used to identify a well kick. The kick detection computing device generate an estimated value for each of the one or more kick indicators during simulated normal drilling conditions and simulated kick conditions. The kick detection computing device determines a deviation value and generates a signal based on the deviation value. The signal activates a green status, an amber warning, or a red alarm to indicate a kick detection status of the drilling system.

Abstract: A container is formed from a one-piece blank including a bottom panel, first and second opposed side walls, and first and second end walls. A top lid panel is foldably attached to the first side wall and a bottom lid panel is foldably attached to the second side wall. A plurality of reinforcing locking tabs is formed in the respective top and bottom lid panels. Each of the respective plurality of reinforcing locking tabs is sandwiched between their respective inner panel and middle panels so as to prevent the side walls from being distorted upon outward pressure applied to these side walls when the container is unreasonably over-packed during shipping and transportation.

Abstract: A process for preparing a bimodal emulsion of viscous hydrocarbon in water includes providing a stream of water at ambient temperature; providing a liquid additive that tends to gel when mixed with water at temperatures less than a gelling temperature TG; heating the stream to provide a heated stream at a temperature TC which is greater than ambient temperature and less than the gelling temperature TG; feeding the heated stream to a mixer having a mixer inlet so as to impart energy to the heated stream; adding the liquid additive to the heated stream downstream of the mixer inlet, whereby the liquid additive mixes with the stream and the energy inhibits gelling of the liquid additive to provide a substantially homogeneous solution of additive in water. The solution is then divided and used to make two different droplet sized emulsions which are mixed to form the bimodal emulsion.
