Abstract: A shield includes a cover, a first frame, and a second frame. The first frame is configured to be attached to a first side of a circuit board. The second frame is configured to be attached to a second side of the circuit board. The cover is configured to be attached to the first frame and the second frame such that the cover is configured to overlap a portion of the first side of the circuit board, a portion of the second side of the circuit board, and a portion of a third side of the circuit board. The cover, the first frame, and the second frame are configured to together define a housing. An apparatus includes the shield and the circuit board.

Abstract: A chuck includes a body having a nose section with an axial bore and a plurality of passageways formed therein, and a plurality of jaws disposed in the passageways. A nut for driving the jaws is rotatably mounted about the body and a sleeve defining a first recess and a second recess is rotatable with respect to the nut between a first rotational position and a second rotational position. An array of locking teeth is fixed to the body and a pawl member with an engagement portion is non-rotatably fixed to the nut. The engagement portion is received in the second recess and engages the locking teeth when the sleeve is in the second rotational position, the engagement portion being compressed so that an amount of force is exerted on the nut in the closing direction by the engagement portion.

Abstract: A chuck including a body having a nose section, a tail section and a center axis, the nose section defining an axial bore and a plurality of passageways. A plurality of jaws is disposed in the passageways, a nut is rotatably mounted about the body so that rotation of the nut either moves the jaws toward or away from the center axis, and a sleeve that is rotatably mounted about the body, the sleeve being rotatable with respect to the nut between a first rotational position and a second rotational position. An annular array of locking teeth is non-rotatable with respect to one of the body and the nut. A lock ring includes at least three projections and is axially movable so that, when engaged, the projections and the locking teeth resist the lock ring from rotating in the opening direction with respect to the body.

Abstract: A method of determining the effectiveness of marketing content comprising the steps of recording user access to items of marketing content. Recording customer transactions, and for each transaction, identifying previous access to items of marketing content by the same customer. Assigning a value to each of the identified accessed items of marketing content, the assigned value being derived from the value of the transaction. Then combining the values assigned to each accessed item of marketing content by the different transactions to provide a customer score for that item, and deriving a performance score for each item of marketing content from the customer score for that item and the recorded user access for that item.

Abstract: A chuck including a body having a nose section with an axial bore formed therein, a plurality of jaws in communication with the axial bore, a sleeve rotatably mounted about the body in operative communication with the jaws, the sleeve defining an annular groove adjacent its rear perimeter, a rear cover defining an annular ridge that is received in the annular groove of the sleeve, and a bearing having a first race, a second race and at least one bearing element, wherein one of the first race and the second race defines a ratchet, wherein the other of the first race and the second race defines a pawl, the ratchet and the pawl are configured so that when the pawl engages the ratchet, the ratchet and pawl prevent the second race from rotating in the opening direction with respect to the first race.
