The present disclosure relates, in one embodiment to a multimedia display apparatus. The multimedia display apparatus may comprise a housing which may be connected to a chassis. The chassis may be configured to attach to the underside of a music drum via a biasing element, thereby positioning the housing so as to project a multimedia image onto the head of the music drum. A multimedia projector may be disposed inside the housing and configured to project a multimedia image through the open bottom or transparent surface of the music drum and displayed on the top surface of the white or translucent drumhead.

Multimedia display apparatus and method of use thereof

A dual-mode Johnson noise and DC resistance thermometer capable of use in control systems where prompt indications of temperature changes and long term accuracy are needed. A resistance-inductance-capacitance (RLC) tuned circuit produces a continuous voltage signal for Johnson noise temperature measurement. The RLC circuit provides a mean-squared noise voltage that depends only on the capacitance used and the temperature of the sensor. The sensor has four leads for simultaneous coupling to a noise signal processor and to a DC resistance signal processor.

Dual-mode self-validating resistance/Johnson noise thermometer system

Method and device for direct, non-contact temperature measure of a body. A laser beam is reflected from the surface of the body and detected along with the Planck radiation. The detected signal is analyzed using signal correlation technique to generate an output signal proportional to the Johnson noise introduced into the reflected laser beam as a direct measure of the absolute temperature of the body.

Optical Johnson noise thermometry

A portable cooler comprising a cooling compartment having a pair of wheels coupled thereto at one end thereof and having a handle positioned on and coupled to one side of the cooling compartment opposite said wheels for pulling the portable cooler. The handle is angularly adjustable about an axle when the cooler is being pulled and is secured to the cooler when not in use. A pair of lifting handles are positioned on opposite sides of the cooler for lifting the cooler to and from a vehicle.
