  • Patent number: 10434379
    Abstract: A golf club head according to one or more aspects of the present invention may include a face portion or strike-face wall comprising a top inner boundary, an intermediate inner boundary, and a bottom inner boundary having a bottom-inner-boundary toe portion and a bottom-inner-boundary heel portion. The strike-face wall may further include a first uniform-thickness region, adjoining the top inner boundary, and a variable-thickness region adjoining the uniform-thickness region and a majority of the bottom inner boundary. In another example, the variable-thickness may adjoin a majority of the top inner boundary and the uniform-thickness region may adjoin a majority of the bottom inner boundary.

  • Publication number: 20190255498
    Abstract: According to one or more embodiments, a fluid catalytic reactor may include a riser, a lower reactor portion, a transition portion, and a flow director. The riser may include a cross-sectional area, and the lower reactor portion may include a cross-sectional area. The transition portion may attach the riser to the lower reactor portion. The cross-sectional area of the riser may be less than the cross-sectional area of the lower reactor portion such that the transition portion is tapered inward from the lower reactor portion to the riser. The flow director may be positioned at least within an interior region of the transition portion. The flow director may include a body which affects the velocity profile of fluids moving from the lower reactor portion to the riser.

  • Patent number: 10335280
    Abstract: A method for treating a human patient includes emitting ultrasound energy from an ultrasound transducer positioned remotely from target tissue of the patient. The ultrasound transducer is positioned at a desired location relative to the patient and target tissue using location and imaging techniques. The method further includes focusing the ultrasound energy such that one or more focal points are directed to the target tissue of the patient and ablating the target tissue at each focal point. The target tissue is ablated via the focused ultrasound energy without ablating non-target tissue through which the ultrasound energy passes between the ultrasound transducer and the one or more focal points.

  • Publication number: 20190170700
    Abstract: A nondestructive bond strength testing method, including: coupling an expendable device to a structure under test, the expendable device including a patterned planar array of exploding bridge wires; simultaneously vaporizing the patterned planar array of exploding bridge wires by applying a pulse of electrical energy to the patterned planar array of exploding bridge wires; and sensing an initial disbonding signature of the structure under test.

  • Patent number: 5949046
    Abstract: The present invention relates to an apparatus (10) for issuing integrated circuit cards (9). The apparatus includes an integrated circuit card writer (12) arranged to issue each of the integrated circuit cards (9), with information stored therein. The apparatus (10) also includes a magnetic stripe card reader (16) which is arranged to read information from a magnetic stripe card (2) inserted therein and to transmit the information to the writer (12) to be written into a blank integrated circuit card (9) stored in the writer (12). A key pad is provided (22) for entering identifying information in respect of the user of the magnetic stripe card (2) is also provided.

  • Patent number: 5739876
    Abstract: An apparatus comprises a display panel having a back side and a front side. A mirrored surface receives sunlight and reflects the sunlight towards a lens system. The lens system focuses the reflected sunlight and directs the focused light towards the back side of the display panel to provide backlighting for the display panel. The backlighting enables the front side of the display panel to be viewed with improved contrast. Preferably, the display panel is of the liquid crystal display (LCD) type, and the mirrored surface is parabolic in shape.
