Abstract: A system for making a dental restoration, comprising a 3D digitizer for producing a 3D model digital representation of a dental restoration model, a computer in communication with the 3D digitizer and capable of creating a dental restoration milling trajectory for a selected block of given dimension and given dental restoration material, based on the 3D model, and a laser milling apparatus in communication with the computer and capable of laser milling the dental restoration from the selected block positioned therein using the milling trajectory created by the computer. The laser milling apparatus includes one or more sensor for continuously monitoring the laser milling of the selected block and to provide feedback to the computer such that the milling trajectory is continuously adjusted by the computer using the feedback from the one or more sensor.

Abstract: A system for maintaining data connectivity in a satellite communications system including a satellite terminal with a ping mechanism, a satellite ground station, and a ping server, where the ping mechanism pings the ping server and restores data connectivity between the satellite terminal and the satellite ground station.

Abstract: A new building material made of chopped straw, cement, mortar cement or lime combined together with a bonding agent is pressed into building blocks of different sizes and shapes. The blocks come in different sizes and shapes to serve different building needs and/or to fit an integrated assembly system. The blocks are interlocked or fitted to correspond to specific requirements. Depending on the proportions of the elements and the pressure exercised to make the blocks, the density can be controlled to increase either the insulation value or the structural value. The grooves, which are part of the interlocking system, can also be filled with concrete either vertically or horizontally or both to create a stronger structure calibrated according to additional structural needs. The resulting concrete structure can also be reinforced with steel rod to further increase its strength. This building material is highly adaptable and environmentally friendly.

Abstract: A door for a computer case is provided which can be moved to a blocking position for blocking access to bays and/or drives of the case. The door can be attached to the case by a slide connection for sliding it along the front of the case between its blocking and accessing positions. In the preferred form, the case is a vertical tower type of case and the door is preloaded on track guides so that when it is raised such as to the blocking position it will not fall back to the accessing position under the influence of its own weight. A gear drive can be provided between the door and housing to provide for smooth manual sliding of the door to readily allow the door to be pushed to overcome the frictional resistance provided by the preload without hang ups in the track guides.
