Abstract: Systems and methods for breaking a material are provided. In one embodiment, a system for breaking a material comprises a device configured to generate a force or torque on a material. The system further comprises at least one controller coupled to the device. The controller is configured to select at least one degree of freedom and an initial direction to apply the force or torque with the device. The controller is further configured to oscillate the force or torque at a first series of frequencies while applying the force or torque in the initial direction with the device by providing commands to the device.

Abstract: Systems and methods for a steered beam horn antenna are provided. In one embodiment, a steered beam horn antenna system comprises: a steerable horn antenna comprising: an adjustable flare component; and a waveguide component having a rear port that opens to a waveguide interface and a frontal port that opens to the adjustable flare component. The adjustable flare component includes: a first outer horn plate configured to rotate about a first pivot line; and a second outer horn plate configured to rotate about a second pivot line. The system further comprises at least one actuator and a controller that operates the actuator to position the first and second outer horn plates into asymmetrical positions with respect to a boresight axis of the steerable horn antenna in response to an input command.

Abstract: A golf putter head is characterized by one or more axis of symmetry, formed by an extrusion process. The extrusion has provisions for multiple styles, masses, lofts, lies, and colors, of golf club heads to be made from the same extrusion process and from the same extruded bar. Golf putter embodiments have provisions for differing head balances, including center, toe, and face balance in two faced, cavity back, or rounded back styles without changes to the extrusion process. The width of the putter may be altered for different total mass of the putter as desired. A novel method of securing mass and inertial altering material inserts is demonstrated with the use of wall tapered cavities which securely lock the insert material without the use of pins, screws, threads, or glues. Novel use of materials which expand upon cooling are introduce for these insert.
