Abstract: An artificial lift assembly and method relating thereto where a sleeve system is disposed above an electrical submersible pump. The sleeve system has a sliding sleeve at least partially carried within a ported case. The sliding sleeve blocks fluid flow through ports in the ported case. The sliding sleeve is restricted from movement relative to the ported case until a first predetermined pressure is applied to the sliding sleeve. Subsequent to the operating the electrical submersible pump, a plug is introduced to the sliding sleeve so as to block fluid flow through the sliding sleeve, Subsequent to introducing the plug, fluid pressure above the plug is increased until the sliding sleeve moves relative to the ported case such that fluid flow is allowed through the ports. Thereafter removing the artificial lift assembly from the wellbore.

Abstract: An object of the present invention is to provide a power conversion device capable of specifying a failure location of an inverter in detail when an attempt of active discharge fails. There are provided an arithmetic operation circuit 102 that outputs a discharge instruction to control a discharge operation based on a voltage between both ends of a discharge circuit, and an output circuit 203 that outputs a drive signal based on the control signal. The arithmetic operation circuit 102 monitors an amount of the decreased voltage between both the ends of the discharge circuit, an LV read back signal being an output of the arithmetic operation circuit 102, and an HV read back signal being an output of the output circuit 203, and specifies a failure location.

Abstract: A method and user equipment to select an emission power from a set of possible emission powers depending on their location relative to a base station. In a 5G development scenario, a massive number of user equipment will be deployed. The data exchanged by this user equipment is mainly signalling data whose volume generates an overload of the network resources. A resource access scheme called uncoordinated resource access scheme reduces the volume of the exchanged data. So that the base station can decode all signals emitted by the user equipment, it is necessary to have a number of emission power levels greater than the number of user equipment. By proposing the user equipment to select an emission power from a set of possible emission powers depending on their location relative to the base station, the solution allows the base station to decode the signals emitted by a greater number of user equipment.

Abstract: An intraoral device having a main body to be attached to maxillary teeth, the main body including a first region, a second region, and a third region. Mandibular anterior teeth are in contact with the first region. The mandibular anterior teeth in contact with the first region are moved toward the third region while being kept in contact with the second region, which causes the mandible to move anteriorly and superiorly.

Abstract: A non-mydriatic, non-contact ultra-widefield fundus (u-WF) photographic imaging system and method are provided for performing u-WF photographic imaging of the eye. The non-mydriatic, non-contact u-WF photographic imaging system includes an illumination system that delivers trans-pars-planar illumination to the eyeball. This frees the entire pupil to be used for imaging. Freeing the entire pupil to be used for imaging allows a u-WFC of the non-mydriatic, non-contact u-WF photographic imaging system to use a relatively simple optics system to capture an ultra-wide FOV. Eliminating the need to dilate the pupil and the need to make contact with the eye while performing imaging eliminates the many problems associated with mydriatic, contact-mode fundus imaging systems and methods. In addition, the system can be implemented in a way that makes it highly suitable for telemedicine applications in underserved areas where clinics and trained healthcare providers may not be available.

Abstract: Methods of refining a planned trajectory of an autonomous vehicle are disclose. For multiple cycles as the vehicle moves along the trajectory, the vehicle will perceive nearby objects. The vehicle will use the perceived object data to calculate a set of candidate updated trajectories. The motion planning system will measure a discrepancy between each candidate updated trajectory and the current trajectory by: (i) determining waypoints along each trajectory; (ii) determining distances between at least some of the waypoints; and (iii) using the distances to measure the discrepancy between the updated trajectory and the current trajectory. The system will use the discrepancy to select, from the set of candidate updated trajectories, a final updated trajectory for the vehicle to follow.
