Abstract: Via holes are formed in an electrically conductive power plane. Photo-imageable dielectric (PID) material is applied to one side of the power plane filling the via holes. The power plane side with no PID material is exposed to light energy to cure the PID material in the via holes. A developer is used to remove any uncured PID material. Signal plane assemblies comprising a conductive signal plane and a dielectric layer are laminated onto the filled power plane forming a two signal and one power plane (2S1P) structure. In another embodiment, the power plane has PID material applied from both sides. A photo-mask is applied to the power plane and the PID material in the via holes is cured with light energy. A developer is used to remove uncured PID material. Signal plane assemblies, as described above, are laminated onto the filled power plane forming a 2S1P structure.

Abstract: Methods, systems and computer program products are provided for which associate physical links of a network device to aggregator ports of the network device where there are more physical links of the network device capable of aggregation than aggregator ports of the network device. Physical links are associated with the aggregator ports of the network device based on a session invariant characteristic of the physical links until either all of the aggregator ports of the network device have been associated with physical links or all of the physical links capable of aggregation have been associated with an aggregator port. The remaining physical links are then utilized as single links to the network device irrespective of the physical link's capability to aggregate.

Abstract: The present invention provides a temperature programmable timing delay system utilizing circuitry for generating a band-gap reference and for sensing the on-chip temperature of an integrated circuit chip. The circuitry outputs the sensed temperature as a binary output which is received by a programmable table circuit of the timing delay system.

The timing delay system further includes a temperature dependent timing delay circuit having inputs for receiving the binary output of the programmable table circuit and an output for outputting a timing delay signal for delaying a clock by a timing delay corresponding to the binary output of the programmable table circuit. The band-gap reference can be a temperature independent band-gap reference voltage having a constant-voltage value or a temperature dependent band-gap reference current having a constant-current value.

Abstract: The present invention is a method and system that enables reference processes that have access to a long running object to maintain the current access to this object while this object performs a re-initialization operation in order to refresh data contained in the object. The system of the invention comprises a long running object manager that controls the re-initialization process of an object registered with the object manager. In operation, a reference program establishes a connection to the long running for purposes of accessing information in the object. This connection to the object is noted in the object manager. At this point, during the connection of the reference to the long running object, there is an event to trigger a re-initialization of the long running object. The object manager notifies the object of the trigger and holds the references that are connected to this object. The object receives the re-initialization signal, performs the re-initialization and sends a reply to the object manager.

Abstract: The present invention provides an improved method, an system, and a set of computer implemented instructions for handling a cache containing multiple single-bit hard errors on multiple addresses within a data processing system. Such handles will prevent any down time by logging in the parts to be replaced by an operator when certain level of bit errors is reached. When a hard error exists on a cache address for the first time, serviceable first hard error, that cache line is deleted. Thus the damaged memory device is no longer used by the system. As a result, the system is running with “N−x” lines wherein “N” constitutes the total number of existing lines and “x” is less than “N”. An alternative method is to exchange the damaged memory device to a spare memory device. In order to provide such services, the system must first differentiate whether an error is a soft or hard error.

Abstract: A method, system, and computer program product for resolving address information in an ad-hoc networking environment. Two indicators are defined to indicate whether (1) a device has a self-assigned (i.e. auto-configured) IP (Internet Protocol) address and (2) the device has an administered IP address (i.e. an IP address configured by an administrator or assigned by a service such as a Dynamic Host Configuration Protocol service). These indicators are communicated, along with a device's IP host name, IP address, subnet, and subnet mask, preferably as augmented information of existing protocol messages. The information may be communicated during establishment of the data link layer connection between two devices, or it may be communicated during service discovery protocol exchanges between two devices, or in a combination thereof.
