Abstract:
A maintenance control system comprises at least one electronics unit including a first wireless communicator, a second wireless communicator configured for association with an individual, and an authentication manager. The authentication manager authenticates access to the at least one electronics unit via wireless communication between the first wireless communicator and the second wireless communicator regarding a maintenance identifier stored within a memory of at least one of the first wireless communicator and the second wireless communicator.
Abstract:
One embodiment disclosed relates to a method for persistently tracking volatile memory faults. A memory error is detected in relation to at least one dynamic random access memory (DRAM) unit on a particular memory module. An entry pertaining to the memory error is written in non-volatile memory of a fault storage unit on that particular memory module. Another embodiment disclosed relates to a memory module that persistently tracks volatile memory faults. The memory module includes a plurality of dynamic random access memories (DRAMs) and a fault storage unit. The fault storage unit includes non-volatile memory configured to store entries pertaining to faults in the plurality of DRAMs on that memory module.
Abstract:
A method of monitoring an electronics system comprises obtaining temperature information via at least one component of the electronics system, and communicating the temperature information from the at least one component to a manager of the electronics system via a wireless communication pathway independent of the components of electronics system.
Abstract:
A tunable delay line system includes a stripline and a plurality of cross-over lines. The stripline defines a propagation delay characteristic. The plurality of cross-over lines are each spaced from and extend with an orientation that is nonparallel with the stripline. Each of the plurality of cross-over lines is configured to be selectively grounded to alter the propagation delay characteristic of the stripline.
Abstract:
One embodiment disclosed relates to a method of visually locating a memory module. An electronic communication is received by circuitry on the memory module to be visually located. A beacon state in the memory module is activated due to receipt of the electronic communication. A beacon device on the memory module is electronically turned on when the beacon state is activated to draw attention to that memory module. Another embodiment disclosed relates to an apparatus to visually locate a memory module in a memory system with a plurality of memory modules. The apparatus includes a system board, a plurality of memory modules, and an LED unit on a memory module. The beacon unit includes a beacon device and control circuitry for turning on the beacon device when an electronic communication to turn on the beacon device is received by that memory module.
Abstract:
A method of monitoring an electronics system comprises providing information regarding at least one parameter of at least one component of the electronics system, and communicating the information from the at least one component to a manager of the electronics system via a wireless communication pathway independent of the electronics system.
Abstract:
An electronics system comprises a frame including a first wireless communicator and at least one component associated with the electronics system. The at least one component includes a second wireless communicator. A manager of the electronics system is in wired communication with the first wireless communicator and configured for determining a compatibility of the at least one component with the electronics system via wireless communication between the first wireless communicator and the second wireless communicator.
Abstract:
The invention in one implementation encompasses the use of special visibility material to enhance the ability of computer-aided visual inspection machines to detect errors in placement or orientation of components mounted to a printed circuit board. In another implementation, the visibility of labels to a repair technician is enhanced by using indicia formed using special visibility material disposed in a housing which substantially restricts the penetration outside ambient light into the interior of the housing.
