Abstract: An illumination system for illuminating a surface includes an optical source (126) for generating light. An asymmetric optic device (112) generates output light by total internal reflection (TIR) of the light from the optical source (126), intensity of the output light being asymmetric with respect to an axis of the asymmetric optic device (126). A diffuser (127) receives and diffuses the output light from the asymmetric optic device (112) to generate diffused light. A cover lens (116) receives the diffused light from the diffuser (127). The cover lens (116) has an etched portion (118) for scattering a portion of the diffused light to generate an output light pattern, the output light pattern having an intensity profile that is asymmetric with respect to the axis of the asymmetric optic device.

Title: Method of manufacturing pure niobium plate end-group components for superconducting high-frequency accelerator cavity
Inventor: NOHARA KIYOHIKO
IPC: B21J1/06
Filed: 2015-06-15
Abstract: The present invention materializes mass production related to an advanced manufacturing method of end-group components from pure niobium plate material for superconducting high frequency accelerator cavities. It converts the conventional full machining or waterjet cutting followed by the conventional cold forging to the whole press-forming. The method includes:  (1) shear-blanking procedure of the pure niobium plate different from the conventional fine blanking, wherein the clearance is set to be a value below 0.5% of pure niobium plate thickness to form a near net shape semi-product; and (2) forging procedure at different temperatures from the conventional hot, warm or cold forging. Press forging is conducted to be free from the occurrence of blue brittleness/necking and to bring about prominent metal-flow, formability, the size accuracy in any portion of a product and the margin of further press-forming by controlling forging temperature to be below 200°C and beyond ambient room temperature.

IPC: G06F21/55
Filed: 2015-06-24
Abstract: In an example embodiment, a system determines a set of instructions from the available instructions for a computer application. The determined set of instructions provides specific functionality of the computer application. The system may determine the set of instructions by performing functional testing and negative testing on the specific functionality. The system may reorganize and randomize the set of instructions in memory and write the reorganized set of instructions to a smaller memory space. For each available instruction not in the set of instructions, the system changes the respective instruction to inoperative to prevent execution of the respective instruction. The system may change the respective instruction to inoperative by overwriting the instruction with a NOP instruction. The system then captures a memory address of the computer application being accessed at runtime. The system may declare a security attack if the captured memory address matches a memory address for an inoperative instruction.

Abstract: A controller for an alternating current contactor comprises a filtering and rectification circuit; an electromagnet component driven by an output of the filtering and rectification circuit and performing actions of attraction, holding or releasing; a power transistor circuit connected to the electromagnet component; and a microcontroller, which controls on or off of the power transistor circuit to control the electromagnet component. The controller comprises a voltage control loop, which provides a voltage feedback signal to the microcontroller; and a current control loop, which provides a current feedback signal to the microcontroller. The microcontroller generates a PWM  control signal according to the voltage feedback signal. The PWM control signal has different duty cycles during the attraction and holding of the electromagnet component so that the current does not exceed a predetermined current threshold. The microcontroller turns off the power transistor circuit upon detecting an overcurrent exceeding the current threshold.
