A portable collapsible drum stick set comprising: a drum stick having at least one handle section and at least one movable section. Each section is formed in an elongated cylindrical configuration with two ends. The drum stick includes a handle section having a hollow interior with one open end and one closed end. Each end includes coupling devices. At least one movable section has a first end and a second end. Each end includes coupling devices. A first end of a movable segment includes an impact tip. Each movable section has a smaller outer diameter than the handle section. Each movable section is adapted to be coupled within the handle section or another movable section having a larger diameter. The coupling devices of the ends of each segment permit securing of the apparatus in an extended or collapsed configuration as desired by a user.

A silicon-based monolithic microwave integrated circuit architecture is described. This architecture, called MICROX.TM., is a combination of silicon material growth and wafer processing technologies. A wafer is fabricated using a substrate of high resistivity silicon material. An insulating layer is formed in the wafer below the surface area of active silicon, preferably using the SIMOX process. A monolithic circuit is fabricated on the wafer. A ground plane electrode is formed on the back of the wafer. Direct current and rf capacitive losses under microstrip interconnections and transistor source and drain electrodes are thereby minimized. Reduction in the resistivity of the substrate material as a result of CMOS processing can be minimized by maintaining a shielding layer over the bottom surface of the wafer. Microstrip and airbridge connectors, salicide processing and nitride side wall spacing can be used to further enhance device performance. The resulting architecture is an alternative to gallium arsenide integrated circuits for microwave applications.

A cell-type atomic frequency standard utilizing a miniaturized gas cell and microwave exciter along with a diode laser light source. The intensity of the diode laser light source counterbalances the penalties associated with the small gas cell. The signal produced by an oscillator is applied to a vapor within the gas cell by a miniature helix coil, or LC gap conductor, or a microstrip exciter. With the dimensions of the gas cell not exceeding one-half the wavelength of the signal, and the associated circuitry formed on a semiconductor substrate, the resulting frequency standard is reduced in size by two orders of magnitude when compared to prior art devices of comparable accuracy.
