Drum beater ball

Abstract

A drum engaging device having a hollow interior and a freely movable body enclosed therein for imparting resonant frequency high sound pressure level with longer (extended) compression domain of member first engagement to the membrane of a drum by varying the weight of the body and varying the time of engagement of the body after the device has engaged the membrane.

Transmission line safety monitoring system

Abstract

A cost-effective transmission line safety monitoring system which detects and tracks acoustic and chemical anomalies along a transmission line to determine if a destructive event is present. One or more sensors, each enclosed in a weather-resistant container, are attached to an antenna and installed as part of the antenna transmitting system on a tower, building top or hill. The acoustic signatures and gas purity deviations are detected and transmitted to a remote master processing center where, via the use of packaged software, the signals are continuously compared to an existing library of acceptable and non-acceptable signatures for pattern matches. An operator, using a PC in a simple WINDOWS.RTM. format, may assign newly acquired signatures to the library for future operation. Different levels of alarms may be triggered and a system shutdown may be initiated, if the incoming signals are similar to or directly match one of the pre-entered non-acceptable signatures, or alternatively, if the gas purity levels are exceeded.

High impact drumstick

Abstract

A drumstick capable of varying the physical characteristics of an impact of the drumstick to a surface thereby varying the sound that the drumstick can produce when playing percussive type impact musical products is disclosed. The drumstick includes an outer, hollow rigid tube-like body member including a handle portion adapted to be held by the hand of a user. A pliable tube-like membrane structure is positioned within the outer hollow body member, the pliable structure changing its shape during use of the drumstick. A liquid medium is located within the pliable structure, the pliable structure being shaped to restrict the liquid to the handle portion of the drumstick, and as a rotational force/motion is applied by a user to the drumstick, the liquid is forced outwardly toward a striking area of the drumstick thereby resulting in a change of balance of the drumstick.

Spark-based igniting system for internal combustion engines

Abstract

A spark-based igniting system for internal combustion engines includes a cylinder, at least one piston, a combustion chamber, a spark insert, and a RF energy source. The piston is disposed within the cylinder for moving slidably between a top dead center position and a bottom dead center position. The combustion chamber is formed in fluid communication with the piston. The spark insert is disposed in a top surface combustion face of the piston. The RF energy source is formed on the cylinder and adjacent to the combustion chamber for generating spark ignition energies to the spark insert to cause igniting of air/fuel mixture within the combustion chamber when the piston reaches near the top dead center position.

Finger-mounted tool device

Abstract

A finger-mounted tool device includes a finger-gripping sleeve formed of a hollow body tube and an abrading member. The hollow body tube is formed of a spirally wrapped progression of a spring material to provide an expanding and gripping nature and is bi-directional in use for fitting securely and comfortably onto any size of a user's finger. The abrading member has an abrasive surface and a backing surface. The backing surface is attached to the body tube.
