Abstract: Techniques are disclosed for systems and methods for providing accurate and reliable compact sonar systems for mobile structures. In one embodiment, a sonar system includes a mounting bracket, a transducer support arm, and a pivoting mechanism pivotably coupling the transducer support arm to the mounting bracket such that, for forces acting on the transducer support arm that are less than a preselected kick-up level, the pivoting mechanism holds the transducer support arm against such forces and at a user selectable first angular position relative to the mounting bracket, and for forces acting on the transducer support arm that are equal to or greater than the preselected kick-up level, allows the transducer support arm to be moved by those forces to a second angular position relative to the mounting bracket.

Abstract: Mixing systems and methods include a mixing device comprising a primary tube having a proximal end, a distal end, an outer surface and an inner lumen and at least one secondary tube having a proximal end, a distal end, an outer surface and an inner lumen. The at least one secondary tube is substantially parallel to the primary tube. The distal end of the at least one secondary tube is fluidly connected to the primary tube at a junction located on the primary tube close to the distal end of the primary tube.

Abstract: Medical guide devices, systems and methods are provided, comprising a base member and a rotatable medical guide component seated on the base member. The guide component defines a path extending through the guide component. The guide component includes a first radio-opaque marker located at a first end of the guide component corresponding with an entry point of the path and a second radio-opaque marker located at a second end of the guide component corresponding with an exit point of the path, and the second end is opposite the first end.

Abstract: An alignment device for an external coil in a transcutaneous energy transfer (TET) system. The device may be adhered to the skin or clothing of a patient and may ensure alignment between an external coil and an internal coil to provide optimal energy transfer in a TET system.

Abstract: A software-defined radio includes an executable radio software system operable with a radio circuit and conforming to the software communications architecture (SCA) specification and defining an operating environment that allows a waveform application to operate with a radio circuit for transmitting and receiving voice and data. An extensible Human-Machine Interface (HMI) plugin module is operable for allowing a selected waveform application to integrate with the radio circuit and provide an HMI user interface.

Abstract: A two-piece ball bat comprising a hollow barrel attached to a handle by a combination of mechanical interference and a layer of rigid adhesive interposed between the interior surface of the barrel and the exterior surface of the handle at a tapered junction. The rigid adhesive layer prevents any direct contact between the barrel and handle thereby eliminating the need to provide any mating features thereon and reducing complexity and cost of manufacture. In an alternative embodiment, glass shafting beads are added to the rigid adhesive compound to ensure even distribution of the adhesive compound, align the barrel and handle and ensure separation prior to curing.

Abstract: Protective face masks and shields are configured so that interior surfaces are associated with visual characteristics based on a use environment. A face shield for a catcher's helmet includes an interior surface having three horizontal zones that are assigned colors, gray levels, color coordinates, or other characteristics based on playing surface characteristics. Upper, middle, and lower interior portions can be associated with blue, green, and brown, respectively.

Abstract: An end configuration for a bat includes in one embodiment an end cap that has a base that is shaped to fit within the open end of the bat thereby to attach the end cap to the bat. The end cap also includes a convexly contoured end surface that is exposed when the end cap is attached to the bat. The end surface is roughened to reduce the aerodynamic drag when the bat is swung, thereby to increase the momentum of the bat for a given amount of force applied to swing the bat.

Abstract: A conveyor lift having a device for engaging a product to transfer the product from a conveyor at one level to a conveyor at another level wherein the lift is driven by at least one drive comprising a motor, and a coupling to couple the motor to the lift wherein the coupling comprises a clutch comprising a pair of drive members which are relatively rotatable about, and axially movable along, an axis, a relievable biasing device to bias the drive members axially towards each other so as to be disengageably connected in torque transmitting relationship and a relieving element operable to release the biasing device to interrupt transmission of said torque and the coupling also incorporating a torque indicating device comprising first and second torque transmitting parts, torque transmitting elements connecting said first and second parts, the device being rotatable about the axis and having torque sensing apparatus on at least one of said torque transmitting elements and responsive to torque transmitted by said

Abstract: A first signal and a second signal are detected. The first and second signals are transmitted according to a timing pattern. An arrival time is identified for the first and second signals. Based on the timing pattern and the estimated arrival times of the first and second signals, a set of parameters is derived that characterize a timing relationship between a first device (100) and a second device (200).

Abstract: Eyewear having easily removable lenses is provided with a frame that defines a first lens receiving recess on one side of a lens opening and a second lens receiving recess on a second side of the lens opening. Each lens has a first tab portion which corresponds with the first recess and a second tab portion which corresponds to the second recess and is mounted by placing the first tab portion in the first recess and the second tab portion in the second recess. Engagement between the respective tab portions and recesses maintains the lenses in the mounted position. To more securely lock each lens in position, a pivot member having a locking tab can be pivoted into a locking position in which the locking tab engages the lens.
