Abstract: An electronic handheld library is disclosed that fully replaces hard copy textbooks and references, audio-visual materials, and successor instructional materials, and receives, stores, and displays other digital data in electronic form. In a single fully integrated design the handheld library meets all six of the specific requirements for a successful launch, development, and operation, specifically focusing on the real requirement; providing excellent presentation quality; possessing inherent high resistance to accidental damage; possessing inherent high theft resistance; providing protection of the source, data, user, and handheld library itself from malicious or accidental events; and providing affordability equal to or better than the objects replaced. Compared to what it replaces, it provides significant advantages for institutional financial management and for students' health.

Abstract: A stout wall assembly which self-transports under remote control or onboard machine logic is disclosed. It combines three very well understood and proven technologies into a novel, new military system for creating protected positions behind very strong cover while a formation is in motion or stationary. The wall assembly is unmanned and is designed to sacrificially block any destructive effects directed at the protected object in its lee. It provides a non-pyrotechnical, passive, always-on, solid, physical barrier defense with no reaction or recycle time whatsoever, an unlimited duty cycle, and minimal possibility of fratricide or collateral damage. It can defeat or degrade kinetic energy, blast, fragmentation, fire, particulate, shaped charge, and high explosive squash head weapons and is uniquely capable against street-level improvised explosive devices.

Abstract: A barrier which is mobile and self-propelled and is controlled by remote control or by self-generated commands created in accordance with pre-loaded or downloaded instructions is disclosed. It can be interposed between a stationary or moving protected object and a suspected threat and maintained in that alignment until updated guidance instructions are received or generated.

Abstract: An area earthquake defense system is disclosed which uses military planning principles; automated command and control systems; the technology of wave manipulation demonstrated in optical engineering, sonar, and anti-tank weapons and their countermeasures; and proven electromagnetic technology. Deeply buried, specially configured, passive devices attenuate, temporally segment, and redirect earthquake shock waves. Such a system, fully integrated into the local geological structure, can reduce the shock reaching the protected area, and, within that area, channel it away from those structures most difficult to protect with single point measures. This is especially true when the plurality of passive devices is complemented by an automated decision and command loop and dynamically reconfigurable active devices embedded at a variety of depths.
