The present disclosure is directed to systems and methods for determining an end of life state for an electromechanical surgical system. The system includes an end effector configured to perform at least one function and a shaft assembly being arranged for selectively interconnecting the end effector and a hand-held surgical instrument. The hand-held surgical instrument includes an instrument housing defining a connecting portion for selectively connecting with the shaft assembly. The hand-held surgical instrument also includes a motor assembly, a sensor array configured to obtain an operational parameter of the hand-held surgical instrument, and a controller configured to control operation of the hand-held surgical instrument based on the operational parameter obtained by the sensor array.

A testing method and apparatus for determining whether surgical cartridges have excess drivers. A blade is disposed in the slots of the cartridge and displaced while it contacts the floor of the slot. If an excess driver is encountered, the blade is displaced away from the floor and this movement is detected, preferably by an electronic sensor. The apparatus includes a base plate to which a carriage is mounted, either directly or through other structural members. The carriage is configured to slide along a pair of parallel shafts, and is driven by a pneumatic ram or other linear prime mover. A tooling plate is moveably mounted to the carriage, and the blade is mounted to the tooling plate. Movement by the blade due to excess drivers results in movement by the tooling plate relative to the carriage, which is detected and recorded, such as by a computer.

The invention comprises systems and methods for evaluating changes in the operational efficiency of an HVAC system over time. The climate control system obtains temperature measurements from at least a first location conditioned by the climate system, and status of said HVAC system. One or more processors receives measurements of outside temperatures from at least one source other than said HVAC system and compares said temperature measurements from said first location with expected temperature measurements. The expected temperature measurements are based at least in part upon past temperature measurements.

The position of an object, which may be a user's finger, along a body is sensed capacitively. A measurement circuit meters the simultaneous injection of electrical charge into the two ends of the body, which may be shaped as a straight line or as a curve. A computing device computes the ratio of the relative changes in the amount of charge injected into each end of the element. The result of this computation is a one dimensional coordinate number plus a detection state indication, both of which can be fed to another functional element, such as an appliance controller, which interprets the coordinate and detection state as a command or measurement.

Apparatus is provided having a signal processor configured to: respond to stimuli caused by a vibrating machine or structure and capture a sampled data set containing information about the stimuli, including where the stimuli include at least vibration of the vibrating machine or structure; and determine wireless signaling containing a pre-selected subset of information from the sampled data set that can be provided as relevant data that includes a relevant data package / sample, the size of the relevant data package / sample, and computations upon the relevant data package / sample, based upon implementing a data interpretation algorithm that uses a wireless communication capacity or protocol for communication. The apparatus may include a data collector or sensor having the signal processor arranged therein and configured for coupling to the vibrating machine or structure to be monitored.

A shoe has a sensor system operably connected to a communication port. Performance data is collected by the system and can be transferred for further use via the communication port. The shoe may contain an electronic module configured to gather data from the sensors. The module may also transmit the data to an external device for further processing. The collected data can be further processed for a variety of different uses or applications.

The invention discloses a combined vibration damper of a screw drill complete machine test-bed and a manufacturing method thereof. The combined vibration damper comprises a vibration attenuation base which comprises a loading system base, a first clamping system base and a second clamping system base, wherein the loading system base is arranged on an equipment foundation in a rigidity way; the first clamping system base and the second clamping system base are connected into a whole through a bolt and are arranged on the equipment foundation through a rubber vibration attenuation block; an interval of 30-50 mm is reserved between the loading system base and each clamping system base; the first clamping system base and the second clamping system base are respectively internally provided with a plurality of cubic cavities with an equal size; the volume of each cubic cavity is 0.1-0.2 cubic meter; discrete type balance weight sand is respectively filled into the cubic cavities, and the filling efficiency is 80-90 %; and the weight of the balance weight sand is 25-35 % of the total weight of the whole device. The test-bed is capable of restraining resonance and testing precisely in the testing process by the combined vibration damper, and the usage precision of surrounding working devices is not affected.

Systems and methods compute dysfunctions via mapping of tri-axial accelerations of drill pipe into drill-string motions. The methods remove gravitational and centripetal accelerations to yield corrected acceleration data due to the vibration only, transform the corrected acceleration data, and maps resulting transformed acceleration data into continuous drill-string positions. The maps provide 2D / 3D visualization of drill-string motions to enable real-time optimization and control of well drilling operations and other scenarios where proactive detection of temporal events in automated systems may aid in avoiding failures.

Methods and systems for measuring and gathering data relating to publication usage by participants in publication readership studies. Some methods and systems employ portable monitors carried by participants of the studies along with publications fitted with various devices, such as piezoelectric transducers, RFID tags and others devices and circuits.

A system and method for performing a measurement task. A node is displayed in a graphical program, and configured to receive a measurement task specification (MTS). The node may be coupled to an MTS node, or to a configuration node which constructs the MTS at run time. When the program executes, the node receives the MTS, invokes an expert system to analyze the MTS, optionally validate the MTS, generates a run-time specification for the task. The node them invokes a run-time builder to analyze the run-time specification and generate a run-time based on the run-time specification, where the run-time is executable to perform the measurement task. The node may be a read node, a write node, or a start node connected to a read or write node. Additional operations may be performed prior to or during the first iteration, and / or during or after the last iteration, of the task.
