  • POWER SUPPLY DETECTING CIRCUIT
    Publication number: 20120044078
    Abstract: A detecting circuit includes an indicating light, a switch component, and a control component. The indicating light indicates whether a voltage rail output by a power supply is within a predetermined voltage range. The switch component has a first terminal connected to the voltage rail, a second terminal connected to the indicating light, and a control terminal. The control component is connected to the control terminal of the switch component. The control component switches on the switch component to power on the indicating light when the voltage rail is within the predetermined voltage range, or switches off the switch component to power off the indicating light when the voltage rail is out of the predetermined voltage range.

  • AUTHENTICATION OF BINARIES IN MEMORY WITH PROXY CODE EXECUTION
    Publication number: 20090327711
    Abstract: Presented is an anti-tampering method that validates and protects specific sections of a binary file. In one embodiment, this method permits a proxy engine to execute (via emulation by a virtual machine) the protected code on behalf of the binary in kernel mode upon successful completion of an integrity check. The integrity check can optionally check only the specific parts of code that the developer wishes to validate. The integrity check can cross binary boundaries. Moreover, the integrity check can be done on a hard drive or in memory. Furthermore, since the encrypted code is executed by the proxy engine in kernel mode, hackers are further deterred from modifying the code. Additionally, a method of creating a protected binary file is described herein.

  • Polarization maintaining coupler
    Patent number: 7373028
    Abstract: A polarization maintaining coupler is provided that allows a user to change the coupling ratio of two or more output fibers. The coupler can include an assembly containing a PM fiber in a ferrule. The ferrule is attached to a housing, which includes a lens for collimating light from the PM fiber onto an optical component that splits the incoming polarized light into two orthogonally polarized components. Each of these orthogonal components is then output into a separate PM or single mode fiber. By rotating the input PM fiber with respect to the optical component, the coupling ratio of the output fibers can be changed. This change in the coupling ratio can be accomplished either by rotating the input PM fiber, or by rotating the optical component together with the output fibers.
