We disclose a process for purification of hydrocarbons, suitable for a wide range of contexts such as refining bunker fuels to yield low-sulphur fuels, cleaning of waste engine oil (etc) to yield a usable hydrocarbon product, recovery of hydrocarbons from used tyres, recovery of hydrocarbons from thermoplastics etc, as well as the treatment of crude oils, shale oils, and the tailings remaining after fractionation and like processes. The method comprises the steps of heating the hydrocarbon thereby to release a gas phase, contacting the gas with an aqueous persulphate electrolyte within a reaction chamber, and condensing the gas to a liquid or a liquid/gas mixture and removing its aqueous component. It also comprises subjecting the reaction product to an electrical field generated by at least two opposing electrode plates between which the reaction product flows; this electrolytic step regenerates the persulphate electrolyte which can be recirculated within the process. The process is ideally applied in an environment at lower than atmospheric pressure, such as less than 1500 Pa. A wide range of hydrocarbons can be treated in this way. Used hydrocarbons such as engine oils and sulphur-contaminated fuels are prime examples, but there are a wide range of others such as hydrocarbons derived from the pyrolysis of a material having a hydrocarbon content. One such example is a mix of used rubber (such as end-of-life tyres) and used oils (such as engine oils, waste marine oils), which can be pyrolysed together to yield a hydrocarbon liquid which can be treated as above, and a residue that provides a useful solid fuel.

Some of the systems include a non-invasively adjustable implant, which includes a driven magnet, and an external adjustment device, which includes one or more driving magnets and one or more Hall effect sensors. The Hall effect sensors of the external adjustment device are configured to detect changes in the magnetic field between the driven magnet of the non-invasively adjustable implant and the driving magnet(s) of the external adjustment device. Changes in the magnetic fields may be used to calculate the force generated by and/or a change in dimension of the non-invasively adjustable implantable medical device.

A sterile barrier assembly includes a tab sliding along a sliding path in a cavity of the sterile barrier assembly and a barrier membrane partitioning the cavity into a sterile side and a non-sterile side. The barrier membrane moves with the tab as the tab slides along the sliding path. A first portion of the tab interfaces with an output of a surgical tool driving unit on the non-sterile side. A second portion of the tab interfaces with a tool driver of a surgical tool on the sterile side.

Certain aspects relate to systems and techniques for driving axial motion of a shaft of a medical instrument using a drive device. Axial motion can include insertion and/or retraction of the instrument. For example, a robotic medical system can include a medical instrument comprising an instrument base and a flexible shaft configured for insertion into a patient, and a first robotic arm attachable to the instrument base of the medical instrument. The system also includes a drive device configured to engage the flexible shaft, and a second robotic arm attachable to the drive device. The second robotic arm is configured to operate the drive device to drive axial motion of the flexible shaft, and the first robotic arm is configured to move in coordination with operation of the drive device.

Systems and methods of recentering an input control include a control unit configured to suspend teleoperated control of an end effector by the input control in response to a recentering request, determine a recentering move for the input control to provide positional and orientational harmony between the input control and the end effector, execute the recentering move, and reinstate teleoperated control of the end effector by the input control. In some embodiments, to determine the recentering move the control unit is configured to determine one or more first positions associated with the end effector, map the first positions to a view coordinate system, map the first positions from the view coordinate system to a console workspace coordinate system, and determine one or more second positions for one or more control points on the input control, the control points corresponding to the mapped first positions in the console workspace coordinate system.

A system and a method are provided for simulating a breast deformation of a subject using sensor data obtained from an orientation sensor of a mobile device, with the orientation sensor being configured for sensing an orientation of the mobile device with respect to a direction of gravity. In accordance with the system and method, model data is accessed which defines a biomechanical model of a breast. A simulation subsystem is provided for obtaining the sensor data from the orientation sensor of the mobile device and for determining a gravitational breast deformation by applying a gravitational force to the biomechanical model in a direction which is defined based on the orientation of the mobile device. A deformed model may be displayed on a display of the mobile device. The system and the method provide an intuitive way of simulating the breast deformation.

An electrosurgical resection instrument for applying to biological tissue radiofrequency electromagnetic energy has a protective hull comprising a shaped piece of dielectric material mounted to cover an underside of an instrument tip of the instrument. The protective hull acts as a shield to protect tissue that may lie under the instrument tip from damage during treatment. The instrument may be particularly useful in procedures performed in a gastrointestinal tract, where bowel perforation is a concern, or in the pancreas, where damage to the portal vein or the pancreatic duct may occur when a tumor or other abnormality is being resected, dissected or removed.
