Title: Permutation data transform to enhance security
IPC: H04K/
Filed: 2011-02-28
Abstract: One data transformation permutes certain bits in a data input based on other bits in the data input. Another data transformation raises one segment of a data input to a power of a function of another segment, the power being relatively prime to a function of a predefined modulus. The modulus is then applied to the result, and the transformed data assembled. In one key derivation application, a segment of the master key is hashed. Two numbers are derived from another segment of the master key. A universal hash function is applied to the result of the hash, from which bits are selected as the derived key. In another embodiment, an encoded counter is combined with segments of the master key. The result is then hashed, from which bits are selected as the derived key. These algorithms can be combined with each other and with key wrapping algorithms or encryption algorithms to enhance the security of these other applications.

Abstract: PURPOSE:To improve the recovery position accuracy and reduce the damage of an airframe by suspending a wire fixed to the airframe at one end and fitted with a hook at the other end from the airframe, and hooking the hook on a rope horizontally stretched at a prescribed height on the ground to recover the airframe. CONSTITUTION:For the recovery of an unmanned aircraft 1, a command is given to a releasing device on the aircraft 1 from the ground, and one side having a hook 3 of a wire 2 and the hook 3 are released from an airframe. The wire 2 is delivered from a rotary drum by the wind pressure applied to the wire 2 and hook 3 in the towed state by the aircraft 1.

Title: Switching and maintenance mechanism for rotor
Inventor: MOCHIDA MIKIO
IPC: A01F17/02
Filed: 1995-03-30
Abstract: PURPOSE: To quickly energize and maintain a rotor in its switching direction and also to stably energize and support the rotor at its switching/revolving side even when a small switching/revolving angle is set at one of both sides of the rotor and toward the other side by largely revolving a changeover piece in its side direction and therefore increasing the energization/maintenance force that is generated by a spring. CONSTITUTION: When a rotor 5 is switched and revolved around a spindle 6 from one of both sides of the rotor 5 to the other, the stretching direction of a spring 73 is changed to one of both sides to the other of the spindle 6 over a fulcrum. At the same time, an actuation arm 60 is added to the spindle 6 and the middle part of a changeover piece 70 is pivotally supported at the end part of the arm 60 in freely oscillating/rotating way. At the same time, the spindle 6 is interfitted through a slit 71 formed at one of both sides of the bar 70 with the other side of the bar 70 connected to the spring 73 attached to a fixing member 1a. Then the bar 70 is moved from one of both sides to the other of the slit 71 through a fulcrum according to the switching and revolving actions of the rotor 5.  In such a constitution of a switching/maintenance mechanism, the rotor 5 can be energized and maintained in its switching direction.

Filed: 1978-08-17
Abstract: PURPOSE: To meaure flow speed and rate and detect the fluid flowing direction by detecting an alternating force generated in an eddy generator by Kalman eddy and taking out it as an eddy signal.  
     CONSTITUTION: When a measured fluid is flowed in tube path 1, eddy generator 2 generates Kalman eddy, and the stress change in the reverse direction is generated while interposing the center axis by receiving alternating force G and is transferred to a piezo-electric element fitted to generator 2 in one body, and signals corresponding to the fluid vibration are generated in sensors 31 and 32, so that the eddy generation frequency can be detected. Meanwhile, a resistance acts on the eddy generator, which is arranged on tube path 1, due to the fluid flow, and signals corresponding to the resistance are generated in sensors 33 and 34, and the fluid flow direction can be detected by measuring the polarity of these signals.
