Abstract: Methods and systems for sensing overvoltage in an electrical circuit are provided. In one implementation, an overvoltage sensor is provided that includes a first connector operable to be connected to a second connector of a provided electrical circuit, in which the second connector includes a first lead connected to a first voltage in the provided electrical circuit. The overvoltage sensor further includes an indicator circuit coupled to the first connector, in which the indicator circuit is operable to sense overvoltage of the first voltage responsive to the first connector being connected to the second connector.

Abstract: The invention is directed to memory multi-bit error correction and hot replace without mirroring. A memory configuration in accordance with an embodiment of the present invention includes: a plurality of memory modules; a memory controller for reading/writing data from/into the memory modules; and an error correcting memory module for storing an error correcting code for each address contained in the plurality of memory modules.

Abstract: A method, system and apparatus for identifying unauthorized access to memory locations in a multi-element data storage device. The invention includes a restrictive key that is physically coupled to at least one inaccessible memory element in the data storage device. The key prevents the user from accessing the data in that element. A securing device connects the restrictive key to the data storage device's housing. When the key is altered from its initial position, the securing device is broken. Because the securing device is at least partially located on the outside of the device housing, it is readily visible. Therefore, if the securing device has been broken, the key to which the securing device was coupled was necessarily moved. This provides visual evidence that there has been an attempt to access one or more data memory areas that had been previously been rendered inaccessible by the restrictive key.

Abstract: A method and system for automatically locating a component connected to a planar, such as a printed circuit board, is disclosed. The method and system comprises providing at least one substantially clear latch coupled to the component, mounting a light emitting element on the planar beneath the at least one latch, and activating the light emitting element, thereby illuminating the at least one latch of the component such that the component can be readily located.
