Automated functional testing systems and methods of making and using the same
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.

METHOD OF PROCESSING DATA RECEIVED FROM A SMART SHELF AND DERIVING A CODE
A method of reading and quantifying pressure points or bumps or a product outline to extract a pattern that, when decoded, uniquely defines a product or class of products by defining the theoretical centers of applied pressure, determining the spatial relationship between more than one center or a product outline to define which pattern belongs to which product, and correlating each pattern with templates of stored patterns to determine what product is represented by each respective pattern.

Variability Compensation For Paired Shafts and Sensors
A transmission utilizes an output torque sensor that relies upon magnetization of a section of the output shaft. The sensor produces an electrical current that varies as the torque transmitted by the shaft varies. However, the relationship between output torque and electrical current is impacted by part-to-part variability of the shaft and of the sensor. Conventional methods of compensating for this variability are hampered because the sensors and shafts are not paired until they are assembled into the transmission. A portable test may be used to characterize each shaft and each sensor. This characterization data includes average zero torque current and variability of zero torque current with respect to shaft position. A mapping is selected based on the shaft characterization and the sensor characterization and programmed into the controller.
Torque calibrating system
Generally, the subject matter disclosed herein relates to torque calibrating systems. A torque calibrating system includes a torque arm having a first end and a second end, a stem positioned proximate the first end of the torque arm, the stem adapted to be removably and operatively coupled to a power tong, and a load cell adapted to be positioned proximate the second end of the torque arm.
SENSING DEVICE
A sensing device including a sensor, a triggering mechanism is provided. The sensing device is attachable to a covering positioned in contact with a body such that the triggering mechanism extends between first and second segments of the body. Movement of at least one of the first and second segments activates the triggering mechanism to provide an input to the sensor, actuating the sensor to generate an output defining at least one measurement of the movement. The measurement may be one or more of rotation, translation, velocity, acceleration, and joint angle. An intermediate mechanism may be interposed between the triggering mechanism and the sensor. The sensing device may include a means to process or record measurements corresponding to movement. A system and method of measuring the movement is also provided.
