Abstract: Musicians skilled in the specialization of brasswind instruments often desire to work out the facial muscles in preparation for a wide range of tonal registries. Most mouthpieces for particular brasswind instruments come in a very small variation of diameters and cup depths. This limitation creates problems when looking to improve higher tone or lower tone ranges. Presently, the musician must try to modify a mouthpiece from an entirely different instrument to satisfy this need. This invention focuses on keeping the shank standardized to couple with the matching instrument while allowing the user to change the cup portion of the mouthpiece to differing sizes and depths. This design enables the user to work a much wider range of tonal registers with the simplicity of a threaded connection between the shank and the cup.

Abstract: A reconfigurable network arrangement of resistors and switches is constructed so that it can be coupled to one or more operational amplifiers and selectively programmed so as to set the gain of the resulting amplifier. The configuration of the network arrangement of resistors and switches to include resistors that can be connected in the feedback path in series and in parallel with each other is such as to provide a wider selection of gain settings, without the need to increase the physical area of the switches on a integrated circuit arrangement.

Abstract: A switching circuit for switching a time-varying input signal, the switching circuit comprising: at least one switch including a N-channel MOSFET and a P-channel MOSFET, each having a gate configured to receive a drive signal to change the ON/OFF state of the switch; and a drive circuit configured and arranged so as to selectively apply a pair of drive signals to change the ON/OFF state of the switch, the drive circuit being configured and arranged to generate the drive signals as a function of (a) a pair DC signal components sufficient to change the ON/OFF state of the switch and (b) a pair of time-varying signal components as at least a partial replica of the signal present on the source terminal of each MOSFET so that when applied with the DC signals to the gates of the n-channel MOSFET and p-channel MOSFET respectively, the drive signals will be at the appropriate level to maintain the ON/OFF state of the switch and keep the gate-source voltages of each MOSFET within the gate-source breakdown limit of the

Abstract: A method and system are disclosed for allowing an advertiser or other user to create high-end advertisements via a plurality of software-based, predefined templates. The templates may be customized by a user to configure the appearance, flow, interactivity and other features of an advertisement. The present system further provides a user interface allowing a user to interact with and configure the templates, thus allowing the user to control the appearance, flow, interactivity, transitions, timers, etc. of the advertisement. In addition to controlling these parameters, the templates also allow a user to associate one or more content files, or assets, with an advertisement. Thus, an advertiser may easily incorporate a video or other content into an advertisement.

Abstract: An integrated circuit includes at least three separate power supply terminals, at least one for those portions of the circuit that must accommodate the widest signal-related voltage excursion, at least one for those that experience substantially smaller signal-related voltage excursions, and a common terminal.

Abstract: A true marine portable boarding platform for the sides of boat hulls and boat transoms that attach to the topside of a hull, gunwale or deck of a boat and also provide three dimensional adjustments for adapting to the various boat designs of different boat manufactuers. The boarding platform consists of wooden planking attached to a stainless steel tubular frame having a padded bumper bar. The platform frame is hinged to the telescopic side sections of a supporting carrier bar in such a way as to allow the platform to fold up within the adjusting tubular framework of the carrier bar. The platform's flexible mounting assembly includes (1) a pair of hangar brackets that are swingably attached to the upper sections of the carrier bar and (2) a pair of self-locking deck plates that are insertibly engaged by the adjusting notched pins located on the opposite inboard ends of the hangar brackets.

Abstract: A water ejector and injector attachment for the motor of a boat comprising a motor adapted to be secured to the frame of the boat carrying a propeller at its lower end and defining a cavitation plate extending rearwardly thereof and having a bore therethrough, at least one recess in the lower surface of the cavitation plate; a trim tab projecting downwardly from the cavitation plate and positioned adjacent rearwardly of the propeller, the trim tab having a passageway therethrough having one end communicating with the bore of the cavitation plate, and a plate member integral therewith and having at least one protrusion upwardly extending therefrom, each of said protrusions mating in the recesses in the cavitation plate; an elongated tube provided through the bore in the cavitation plate with one end secured to and communicating with the passageway of the trim tab and the other end terminating in the bilge of the boat; a spring biasing the trim tab upwardly whereby the protrusions engage the recesses in the cav
