  • Publication number: 20240399152
    Abstract: Disclosed herein are methods for treating impairment of a limb in a subject. Particular methods comprise applying a therapeutically effective amount of an electrical stimulus to dorsal roots, dorsal rootlets, or dorsal root ganglia, of sensory neurons innervating the limb of the subject, wherein the impairment is a motor impairment and/or a proprioception impairment due to neurological disorder or injury, the electrical stimulus is applied with one or more electrodes controlled by a neurostimulator, and the one or more electrodes are implanted in the epidural space at the dorsolateral aspect of the spinal cord and proximate to the dorsal roots or dorsal rootlets of the sensory neurons innervating the limb of the subject, or the one or more electrodes are implanted proximate to dorsal root ganglia of sensory neurons innervating the limb of the subject.

  • Patent number: 11035231
    Abstract: Methods and systems for collecting high quality reservoir samples and determining producibility of those samples are disclosed that provide for a non-stop and no shock sampling process. The systems and methods of the present disclosure are especially important collecting samples of reservoir samples in a manner that most closely resembles production fluids and maintains the reservoir at or near the draw down pressure during the pumping and sampling processes.

  • Patent number: 10989049
    Abstract: Methods and systems for collecting high quality reservoir samples are disclosed. The systems and methods of the present invention are especially important in collecting samples of reservoir fluids in a manner that most closely resembles production fluids. The systems include an upper shoe and a lower shoe that are asymmetrically spaced along the axial length of probe module with respect to a sampling probe to allow for the placement of a component compartment proximate the probe. Sensors or modules for testing or analyzing reservoir fluids are positioned within the compartment.

  • Patent number: 10920587
    Abstract: A double piston positive displacement pumping system and methods are disclosed. The pump has a working bore with a first piston defining a pair of working chambers and a separate pumping bore having a second piston defining a pair of pumping chambers. The pistons are coupled together by a connecting rod such that the translate together axially within their respective bore. Working fluid is controllably introduced into and out of the working chambers to force the axial translation of the piston pair and wherein a process fluid is drawn into and out of the pumping chambers. The working fluid and the process fluid are confined to their respective bores and pistons.
