Abstract: A near-infrared spectroscopy system comprises a substrate, a light source emitting a set of wavelengths, an optical detector detecting the set of wavelengths, a processor in electronic communication with the light source bank and/or the optical detector, and a memory device in electronic communication with the processor. The light source bank, optical detector, processor, and memory device are mounted on the substrate, and a battery is in electronic communication with at least one of these components. Program instructions direct the processor to calculate an oxygenation level, compare that oxygenation level to a predetermined threshold, and optionally, activate a feedback device. A method of detecting an oxygenation level comprises mounting the system in a wearable article, calculating a baseline oxygenation level, regularly executing the program instructions to calculate the oxygenation level, and activating the feedback device.

Abstract: A linear actuator has a screw drive having a threaded nut connected to an extension arm tube and a threaded spindle couplable to a motor. A first end of the spindle always projects into the tube and is connected to a piston which partitions an interior space formed by the tube into a first region on the side of the piston opposite to the nut and a second region on the side of the piston facing the nut. The regions are separated in a fluid-tight manner. The spindle is held in position since the nut comprises an annular piston that delimits an annular fluid space between a housing of the linear actuator and the tube in a fluid-tight manner, the hydraulically effective surface of which is the same size as that of the first region. The first region and the annular fluid space are fluidically connected by a switching valve.

Abstract: An electromechanical linear actuator having a threaded drive, which comprises a threaded nut connected to a cantilever tube and a lead screw connected to a hollow shaft of an electric motor via a rotationally fixed connection in such a way that, by a rotation of the hollow shaft and the lead screw, the threaded nut and the cantilever tube are linearly movable. An axial design length of the electromechanical linear actuator in the maximally retracted state is minimized in that a holding brake for the lead screw and a first rotary bearing for bearing the lead screw on a housing of the linear actuator are arranged within the hollow shaft.

Abstract: A linear actuator having a threaded drive including a nut connected to a cantilever tube and a leadscrew coupled to a motor, so that, by rotation of the leadscrew, the threaded nut and the cantilever tube are linearly movable, and, regardless of the position of the cantilever tube, one end the leadscrew projects into the cantilever tube and is connected to a piston which divides an internal space formed by the cantilever tube into a first region on the side of the piston opposite the threaded nut and a second region on the side of the piston facing the nut. The two regions are separated from one another in a fluidically sealed manner. A relief of the threaded drive is improved since the first region is connected to a pressure accumulator to generate a relief pressure in the first region using the first pressure source.

Abstract: An electromechanical linear actuator includes a threaded drive which has a threaded spindle and a threaded nut. The threaded spindle is coupled to a hollow shaft of an electric motor via a rotationally fixed connection. The threaded nut is fastened to a linearly movable extension tube. In a maximally retracted state of the extension tube, the threaded nut is retracted at least in portions, preferably completely, into the interior of the hollow shaft. During operation of the linear actuator, the threaded spindle rotates and is not moved linearly. The threaded nut does not rotate and is moved linearly.

Abstract: A servohydraulic drive includes a hydrostatic displacement machine, an electric machine that is mechanically speed-coupled with the displacement machine, a hydraulic cylinder that is fluidically connected to the displacement machine via first and second working lines, a hydraulic accumulator, and a supply unit. The displacement machine has a stroke that is adjustable via a hydraulic adjustment device. The cylinder is configured to be activated by reversal of the fluid flow through the displacement machine in opposite directions. The accumulator is preset to a low pressure and is fluidically connected via a valve assembly in each case to the lower pressure working line. The supply unit is configured to supply the adjustment device with pressurized fluid under the necessary pressure for the adjustment regardless of the present pressure in the working lines such that the displacement machine is configured for an active and load pressure-independent adjustment of its stroke volume.

Abstract: Online advertisements are delivered to one or more users. An authorization to access one or more data streams for a given user is received. The authorization is explicitly granted by the user. The data streams are stored within a user data repository. Upon the user conducting an online action that initiates a dynamic advertisement (DA) request, the authorized data streams for the user are used to generate a customized DA that is optimally relevant to the user. The customized DA is then delivered to the user. The customized DA is also monetized.

The method includes generating an altered component plan by altering a component plan for a component, computing a mean production value using the altered component plan, and computing the component gating risk using the mean production value.

Abstract: A method for forecasting the component surpluses for a target planning period is provided. To begin this method, a planner first identifies each component required to produce a product. For each component, the planner defines a planned level and an uncancelable level. The planned level for a component is the quantity at which the component is expected to be available. The uncancelable level for a component is the quantity of the component that cannot be liquidated without charge. The planner also defines a vector of connect rates for the components. After the required data has been entered, an expected surplus is computed for each component. To compute a component's expected surplus, the component is assumed to be available at its uncancelable level. The remainder of the components are assumed to be available at their respective planned levels.

Abstract: A representative implementation of a method begins when a planner captures assumptions about products and components in an entity called a “scenario.” A scenario is the parameterization of all the demand, financial, and operational information for a portfolio of products and components across a set of time buckets (planning periods). The planner then specifies a component plan to be analyzed, which identifies the quantities of each resource that will be used or procured during each planning period. A request for analysis includes one or more analysis parameters that will be used in order to evaluate the performance and the risks associated with the component plan and scenario. The request for analysis is submitted to an analysis engine for calculation of risk indicators. The analytical engine calculates all the performance indicators and returns the results. The results are then typically stored in a database or other persistent storage system.

Abstract: A method for forecasting the mean production (the expected production) for a target planning period is provided. To begin this method, a user, or planner chooses one or more products for which the expected production is desired. The user then enters data describing each selected product. The data entered for each product includes data describing the demand for that product as well as data describing the components required for each product. Inter-product dependencies are also entered. The expected production for each selected product for the target planning-period is expressed as a sum of multidimensional integrals involving the data entered in the previous two steps. Once formulated, the integrals are evaluated. The result of this computation is then presented to the user.
