Compact Disc Case (U-1997)

Current compact disc cases are often difficult to open. The design requires one's hand to span the length of the case in order to open it. This requirement is of particular concern to those people who have small hands or those who have limited use of their hands. Further, the disc is held in place by a grasping hub. The hub makes the use of force necessary to remove the disc from its case and the disc may become damaged as a result.

An inventor at the University of Utah has developed a unique case design that eliminates the problems experienced with conventional cases. In this design, the position of the disc is maintained within the storage case without the use of a grasping hub. Thus, no force is required to remove the disc from the case.

Additional advantages of this design include the following: the case can be attached to one or more other cases without the use of a secondary storage device and it provides space for the literature that typically accompanies the compact disc.


Physical Data Compression (U-1994)

Storage capacity is an important factor when storing data in binary digit systems. In order to fully utilize the storage capacity, the data is compressed. This compression reduces the amount of space occupied by the data and is usually accomplished through data compression algorithms during the storing process.

A new method, Physical Data Compression (PDC), compresses data further than conventional data compression techniques. PDC is able to store two binary digits of data onto the physical space in the storage medium where it is now possible to store only one binary digit of data. In other words, PDC facilitates an increase of 100% in binary data storage capacity.

Mechanical Chuck and Photo Resist Spinner

The Sample Preparation Spinner System is an economical way to prepare samples because the mechanical spinner assembly can be attached to any D.C. or A.C. motor. It is cost efficient because the spinner system does not require a vacuum pump and an accompanying vacuum-seal motor. The entire Sample Preparation Spinner System (including motor) can be produced for less than $500. Comparable systems (without the vacuum pump) are usually in the range of $3000 to $4000.

Comparable spinner systems are expensive mainly due to the cost of the motor. The motors are of a special design so as to prevent corrosion of internal parts by the corrosive materials commonly used in sample preparation. The cost can be prohibitive because the motors are specialized vacuum-seal motors. In a typical design, the vacuum pump is attached to one end of the motor, while the vacuum chuck is attached to the freely rotating shaft at the other end of the motor. During sample preparation, materials used in the preparation of the sample are drawn into the hollow shaft of the motor. The special design of the motors prevents those materials to come into contact with the vunerable components of the motor. The cost of the development and production of the specialized motors is clearly reflected in the price.

The Sample Preparation Spinner System does not use a vacuum, and thus also saves the user the cost and upkeep of a vacuum pump.

The Sample Preparation Spinner System consists of a mechanical chuck which is coupled to a motor shaft. The assembly consists of two spring-loaded grips which maintain the sample's secure position on the mechanical chuck. The spring-loaded device also insures that the sample is well centered on the mechanical chuck during operation.

Specialized grips may be produced and attached to the grips of the mechanical chuck. These specialized grips may be manufactured to the clients specifications.

Those who have used the spinner system have remarked about the ability to produce samples which do not exhibit the usual excess fluids that are drawn to the underside of the sample by the vacuum system in a vacuum-based system. Furthermore, because of the absence of the vacuum, the sample coating thickness tends to be much more uniform (reduced wicking), and is only dependent on the rotational speed and the viscosity of the preparation chemical.

In vacuum system prepared samples, the vacuum which maintains the samples position on the vacuum chuck also draws some of the preparation chemicals and solvents towards the sides of the samples (wicking), thus creating a very non-uniform coating of the sample.
