Abstract: A “hydraulic rotating machinery” (“HRM”) system provides optimal energy efficiency over a very wide conditions of service (“COS”) range by configuring a plurality of variable speed HRMs in a “cluster.” The HRMs are interconnected by one or more valves that can be actuated by a controller to configure and vary a flow path through which a process fluid flows from an inlet to an outlet. By actively selecting which of the HRMs are included in the flow path, the interconnections therebetween, and the operating speeds thereof, the controller ensures that the HRM cluster continues to operate at optimal efficiency as the COS fluctuates over a very wide range. The HRMs can be identical to each other, or can vary in design. The HRM system can be implemented for storage and retrieval of green energy. The controller can also monitor the health of the cluster and/or of the associated process.

Abstract: A method may include receiving information associated with a transmission of data. The method may include determining a classification for the information associated with the transmission of data. Based on the classification and in response to a trigger, the method may include formatting a portion of the information into a first schema associated with a location service. The method may also include transmitting a request for location information corresponding to the portion of the information to the location service according to the first schema. The method may include receiving, from the location service, the location information according to the first schema and formatting the location information from the first schema to a second schema associated with the computing device. The method may include updating the information associated with the transmission of data to include the location information.

Abstract: The present invention relates to an integrated system and method for EEG signal acquisition and interpretation, for neonatal seizure detection. The system as per the present invention comprises a control device, an integrated circuit, a wireless communication module, a visual indication means, and a power management module. The control device has a Convolutional Neural Network (CNN) embedded on it, and is programmed to configure the integrated circuit to receive a plurality of channels of EEG data from a plurality of EEG acquisition electrodes, and to amplify and digitize the received EEG data. The integrated circuit is further configured to segment the channels of EEG data to a plurality of sequential epochs of EEG data. The control device is configured to pass the sequential epochs of EEG data through the CNN which is pre-trained to output the probability of a seizure in the EEG data passed through it.

Abstract: Devices for exchanging properties, such as pressure, between at least two fluid streams and related methods may include pistons coupled to a valve stem. The valve stem and valve body may be configured to define a primary seal between the one or more pistons and the valve body and a secondary seal between the one or more pistons and the valve body.

Abstract: Pressure exchange devices and related systems may include a valve device configured to selectively place a fluid at a first higher pressure in communication with another fluid at a lower pressure in order to pressurize the another fluid to a second higher pressure. Methods of exchanging pressure between at least two fluid streams may include a pressure exchanger having two low pressure inlets.

Abstract: A garment hanger (10) having a rail engaging portion (12) and a stem (14). The stem (14) comprises a first section (16) extending from the rail engaging portion (12) and arranged substantially parallel therewith, a spacer section (18) extending substantially perpendicularly from the first section (16) and a tail section (20) extending from the spacer section (18) and directed towards the first section (16) and/or the rail engaging portion (12). The stem (14) forms a loop with an opening between the end of the tail section (20) and the first section (16) of the stem (14).

Abstract: A centrifugal pump impellor includes balancing holes that reduce axial thrust while minimizing the loss of pump efficiency. In one general aspect, the balancing holes penetrate the rear shroud between the blades, and are angled in both axial and rotational directions so as to direct the leakage fluid approximately parallel to the primary process fluid, so that it causes minimal interference with the primary fluid flow. In a second general aspect, the balancing holes extend from the rear cavity within the impellor blades and through the leading edges of the blades, thereby entering the primary flow in locations where the process fluid is almost static relative to the blades. This minimizes the impact on the flow of the process fluid past the blades, and thereby minimizes the loss of pump efficiency caused by the balance holes. In embodiments, each blade leading edge includes a plurality of balancing hole outlets.
