摘要： There is a strap tension detector for detecting tension in a strap. A housing has an upper portion and a lower portion. The upper portion and lower portion are adapted to receive the strap. A strain beam is mounted to one of the upper portion and the lower portion. The strain beam is arranged at an angle to the strap to extend across the width of the strap when the strap is placed between the upper portion and the lower portion and extending through the first and second strap-receiving openings so that the strap bears on the strain beam when taut. A strain gauge is operatively connected to detect strain across the strain beam.

摘要： A calibrated load cell includes a monolithic load beam having a first region, a second region on a distal end of the load beam from the first region for receiving a force from a load, and a third region arranged between the first and second regions, wherein the third region comprises a recess on one side of the load beam. A strain gauge is arranged in the recess for detecting a deformation of the third region from the load and for generating a strain gauge output signal proportional to the deformation of the third region. The load cell also includes a microcontroller arranged in the recess for receiving and processing the strain gauge output signal to produce a load cell output signal that represents the load on a load cell output cable. The microcontroller transforms the strain gauge output signal based on calibration parameters to produce the load cell output signal as a calibrated load cell output signal.

摘要： A sensor system includes a sensor element, a signal processing circuit, and a pseudo-signal correction circuit. The sensor element outputs an electric signal corresponding to an external force. The signal processing circuit converts the electric signal coming from the sensor element into a signal having a certain signal format and then outputs the signal thus converted. The pseudo-signal correction circuit corrects a pseudo-signal outputted by the sensor element. When receiving a test signal, the sensor element performs a self-diagnosis based on the test signal and then outputs the pseudo-signal, which represents a result of the self-diagnosis. The pseudo-signal correction circuit corrects the pseudo-signal based on environment information about an environment where at least one of the sensor element or the signal processing circuit is located.

摘要： An automatic robot control system and methods relating thereto are described. These systems include components such as a touch screen panel (“TSP”) robot controller for controlling a TSP robot, a camera robot controller for controlling a camera robot and an audio robot controller for controlling an audio robot. The TSP robot operates inside a TSP testing subsystem, the camera robot operates inside a camera testing subsystem, and the audio robot operates inside an audio testing subsystem. Inside the audio testing subsystem, an audio signals measurement system, using a bi-directional coupling, controls the operation of the audio robot controller. In this control scheme, a test application controller is designed to control the different types of subsystem robots.
Methods relating to TSP, camera, and audio robots, and their controllers, taken individually or in combination, for automatic testing of device functionalities are also described.-

摘要： Systems and methods to test robotic end effectors may comprise a testing rig having variable mass properties. The testing rig may include a variable weight assembly and a movement assembly that can adjust a position or orientation of the variable weight assembly. In this manner, the testing rig can be modified to simulate or replicate mass properties of a plurality of items, and grasp performance of a robotic end effector may be measured using the testing rig. Further, simulation models of end effectors and items may be validated based on actual grasp performance of a robotic end effector and the testing rig having variable mass properties.

摘要： A method may involve controlling, via a control system, the apparatus to provide a first prompt to place a digit on an outer surface of the apparatus in a fingerprint sensor system area. The method may involve determining, via the control system, a digit force or a digit pressure of the digit on the outer surface of the apparatus. The method may involve controlling, via the control system, the apparatus to provide a second prompt corresponding to the digit force or the digit pressure.

摘要： A method of verifying torque measurements of a reaction torque transducer of an instrument drive unit includes a controller receiving a verification signal, generating an acceptable range of torques, receiving a torque signal, comparing the torque signal to the acceptable range of torques, and stopping a motor if the torque applied by the motor is outside of the acceptable range of torques. The verification signal is indicative of the current drawn by the motor and the torque signal is indicative of torque applied by the motor.

摘要： An apparatus for calibrating a rotational tool includes a communications interface configured to establish a wireless communications link between a rotational tool and a calibrator to communicate one of a tool torque measurement or a calibrator torque measurement via the communications link. The apparatus may further include calibration processing circuitry configured to receive the tool torque measurement measured by a tool torque sensor, and receive the calibrator torque measurement measured by a calibrator torque sensor. The calibration processing circuitry may also be configured to compare the tool torque measurement to the calibrator torque measurement to determine a difference value, aggregate the difference value with previously determined difference values to determine an updated torque calibration factor, and cause a torque calibration factor associated with a torque sensor of the rotational tool to be automatically replaced with the updated torque calibration factor in the memory of the rotational tool.
