Abstract: A chuck including a chuck body that supports a plurality of jaws. An outer sleeve is axially fixed with respect to the chuck body. A nut is coupled to the outer sleeve, and the nut is movable axially and radially relative to the chuck body. The nut interacts with the jaws such that when the outer sleeve rotates, the nut moves axially and radially relative to the body.

Abstract: Pick quality determination is disclosed, including: using a pressure meter to sense a pressure associated with an airflow through a gripper mechanism of a diverting mechanism over time during a pick operation on a target object; storing the sensed pressure associated with the airflow through the gripper mechanism over time as a pressure sequence associated with the pick operation on the target object; and correlating the pressure sequence with representative pressure sequences associated with corresponding pick quality types to determine whether the pick operation on the target object was successful or not.

Abstract: Introduced here are carrier assemblies that include a rigid tray having a deck area with a patterned surface of cavities for receiving semiconductor components. The cavities can be designed to accommodate semiconductor components of different form factors (e.g., having different shapes, sizes, etc.). Moreover, an adhesive film can be affixed to the deck area to ensure that the semiconductor components are securely held against the top surface of the rigid tray. In some instances the adhesive film substantially conforms to the deck area, while in other instances the adhesive film extends across the opening of each cavity located in the deck area. Semiconductor component(s) can be secured to the carrier assembly based on the adhesiveness provided by the adhesive film, mechanical force provided the cavities, electrostatic force provided by the cavities, or any combination thereof.

Abstract: A lawn mower includes a frame, an operator support, a blade assembly, a steering system, a motor assembly, a sensor and one or more processors. The operator support is coupled to the frame and is configured to support the entire weight of an operator of the lawn mower during use thereof. The motor assembly is configured to drive rotatable wheels so as to move the frame along the ground surface and drive at least one blade relative to the ground surface to cut grass. Sensor and processor to detect the an edge between an unmowed area of grass and a mowed area of grass and control the motor assembly stop driving the at least one blade, the wheels, or both based on the input from the sensor.

Abstract: Introduced here is a wafer separator configured to carry a semiconductor wafer with improved efficiency, protection, and reduced costs when utilized in the handling, transport, or storage of semiconductor components. The wafer separator may include a circular ring having an outer edge defining a periphery of the circular ring. The circular ring may include an inner edge defining a central opening of the circular ring. The wafer separator may include a first-right angled recess for receiving a semiconductor wafer that extends downward from a top surface of the circular ring. The wafer separator may also include a second right-angled recess for maintaining a gap beneath the semiconductor wafer when the semiconductor wafer is set within the first right-angled recess. In some embodiments, the wafer separator also includes interlock components for connecting the wafer separator to adjacent wafer separators.

Abstract: In one instance, an attachment device for use in attaching a hook-and-loop patch to Modular Lightweight Load-carrying Equipment (MOLLE) includes a backing member having a central stem and a first cap and a second cap portion. The front side of the device has a hook or loop material applied to it. The first cap has a first wing and second wing. The second cap has a third wing and fourth wing. The backing material is flexible enough to allow the first cap or second cap to be compressed to go through a loop on a MOLLE and then released causing it to return to its original position. In this way, it is attached to a loop on the MOLLE and may then receive a coordinated hook or loop material on the back of a patch. Other embodiments are presented.
