Abstract: A head unit device for controlling motion of an object includes a chamber filled with a shear thickening fluid (STF) and a piston. The piston is housed within the chamber and exerts pressure against the STF from a force applied to the piston from the object. The STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates. The piston includes at least one piston bypass between opposite sides of the piston that controls flow of the STF between the opposite sides of the piston to selectively react with a shear threshold effect of the first range of shear rates or the second range of shear rates.

Abstract: Described is a method for regulating a volume of liquid delivered by a peristaltic pump and a peristaltic pump system that can be used to perform the method. The method includes sensing an ambient temperature of the peristaltic pump. The peristaltic pump includes a pump motor. At least one of a motor speed and a motor operation duration is determined from the sensed temperature, a selected volume of liquid to be delivered and a predetermined correspondence of the motor speed to ambient temperature. The pump motor is operated at the determined motor speed or for the determined motor operation duration to deliver the selected volume of liquid from the peristaltic pump.

Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: A method for thermal management of a power trowel executable by an on-board logic controller allows operation of the trowel in normal mode in which rotor speed is determined by manual control and in which a sensed temperature of the trowel lies below a high temperature setpoint. In response to the sensed temperature exceeding the high temperature setpoint, the controller switches operation of the power trowel from normal mode to thermal management mode in which a maximum rotor speed achievable by manual control is reduced by the controller in incremental steps to allow the trowel to cool. In response to the sensed temperature reaching a low temperature setpoint, the controller increases rotor speed in incremental steps, and returns operation to normal mode when a desired rotor speed is maintained for sufficient time during which the sensed temperature remains below the low temperature setpoint.

Abstract: This invention provides, but is not limited to, novel oleanolic acid derivatives having the formula: wherein the variables are defined herein. Also provided are pharmaceutical compositions, kits and articles of manufacture comprising such compounds, methods and intermediates useful for making the compounds, and methods of using the compounds and compositions.

Abstract: Described herein are systems, methods, and non-transitory computer readable media for defining and executing functions for determining a matching entity that is relevant to an entity of interest when, for example, there is a significant number of intermediary links and entities between the matching entity and the entity of interest. A visual depiction of a path traversal from a seed input entity to an output matched entity can be presented to an end user in a manner that allows the end user to ascertain the sequence of intermediary links and entities that connect the matched entity to the seed entity.

Abstract: Disclosed herein are solvent reservoir systems for steady flow delivery and simultaneous monitoring of solvent level and solvent density within the solvent reservoir systems and methods for monitoring the solvent reservoir systems and providing feedback to a user or adjusting the systems in response to the monitored characteristics.

Abstract: Systems, methods, and non-transitory computer-readable media can obtain data form one or more data sources. The data from the one or more data sources can be processed into one or more data records. Each data record can include at least an identification, a data type, and data to be stored. The data records can be organized into a tree data structure. The tree data structure can be stored as an intermediate data layer in a data analysis platform.

Abstract: Described systems and techniques determine a password change trigger for a password for an account, and access a connection store storing a plurality of password models. Each password model may include at least one password requirement and at least one password change procedure. Based on the password change trigger and from the plurality of password models, a selected password model for the password and the account may be selected. The account may be accessed using at least one selected password change procedure of the selected password model, and the password may be updated in accordance with at least one selected password requirement of the selected password model.

Abstract: An osteometric measuring device that comprises a first panel; a second panel movably positioned with respect to the first panel; and a light emitting device arranged and disposed in the first panel to measure distance by time-of-flight; wherein the light is emitted from the first panel, reflected off of the second panel, and received by the first and measured to calculate the distance from the first panel to the second.

Abstract: Described is an active check valve that uses electro-magnetic actuation for operation. The valve includes a plunger assembly having a magnet in a sealed internal volume. The plunger assembly further includes a plunger tip that extends from either a plunger assembly housing or a sealing member. Although the plunger assembly is disposed in the solvent flow, the magnet is not exposed to the solvent. When the valve is actuated, the plunger tip moves the sealing member to open or close the valve. Optionally, an arming force may be applied to the sealing member in advance of opening or closing to reduce the subsequent additional force necessary to move the sealing member during opening or closing, thereby improving the accuracy of the solvent composition in liquid chromatography system applications.
