20100018603 | STORAGE DEVICE FOR COMPRESSED MEDIA AND METHOD FOR FUELING VEHICLES - A storage device for storing a compressed medium, for example hydrogen. The storage device encompasses a plurality of storage containers and a container, in which the storage containers are arranged. Furthermore a method for fueling a vehicle with gaseous hydrogen by means of a variable pilgrim step method, where the gaseous hydrogen is removed from a storage device, which is divided into at least two, preferably into four or more than four sections and is fed to the vehicle, which is to be fueled. | 01-28-2010 |
20140075964 | PUMPING AND VAPORIZATION SYSTEM FOR ENHANCED OIL RECOVERY APPLICATIONS - A cryogenic liquid such as liquid nitrogen or liquid carbon dioxide is pumped via a high pressure pump to a vaporizer where the liquid becomes gas. The higher pressure gas is cooled by a coolant exchanger and can be fed to an onsite unit operation such as an enhanced oil recovery operation. The coolant exchanger is in a thermal exchange relationship with a combustion engine which powers a hydraulic pump which feed hydraulic fluid to drive the high pressure pump. | 03-20-2014 |

20140222023 | HYBRID CONTROL SURGICAL ROBOTIC SYSTEM - The present disclosure describes a method and system for performing robot-assisted surgical procedures. The system includes a robotic arm system assembly, an end effector assembly, and a hybrid control mechanism for robotic surgery. The robotic arm is a lightweight, bedside robot with a large range of motion, which can be easily manipulated to position endoscope and surgical instruments. The control console is mounted at the distal end of the robotic arm to enable robotic arm to follow operators arm movement, provide physical support, filter out hand tremor, and constrain motion. A universal adapter is also described as an interface to connect traditional laparoscopic tools to the robotic arm. | 08-07-2014 |
