Voice samples are collected from the voice connection at the endpoint. The voice samples are stored in an error log at the endpoint.

Abstract: Intercepting a secure communication session includes distributing a key from a key distribution point to establish a secure communication session between a first endpoint and a second endpoint. A secure channel is established between the key distribution point and an intercepting point. The intercepting endpoint may be determined to be authorized to intercept the secure communication session. The key is provided to the intercepting endpoint only if the intercepting endpoint is authorized to intercept the secure communication session, where the key provides the intercepting endpoint with access to intercept the secure communication session.

Abstract: Selecting a transport address for a call session between a first endpoint of a first region and a second endpoint of a second region includes determining that the call session is being initiated. A relationship between the first region and the second region is determined. One or more transport addresses of the first endpoint are identified in accordance with the relationship to yield one or more selected transport addresses.

Abstract: The invention is directed to techniques for discovering a powerability condition of a computer network such as the existence of a remotely powerable device attached to a connecting medium of the computer network. Such detection can then control whether a remote power source (e.g., a data communications device such as a switch) provides remote power (e.g., phantom power) to the computer network. One arrangement of the invention is directed to an apparatus for discovering a powerability condition of a computer network. The apparatus includes a signal generator, a detector and a controller which is coupled to the signal generator and the detector. The controller configures the signal generator to provide a test signal to a connecting medium of the computer network, and configures the detector to measure a response signal from the connecting medium of the computer network.

Abstract: A method, apparatus, and computer for identifying selection of a bad victim during victim selection at a cache and recovering from such bad victim selection without causing the system to crash or suspend forward progress of the victim selection process. Among the bad victim selection addressed are recovery from selection of a deleted member and recovery from use of LRU state bits that do not map to a member within the congruence class. When LRU victim selection logic generates an output vector identifying a victim, the output vector is checked to ensure that it is a valid vector (non-null) and that it is not pointing to a deleted member. When the output vector is not valid or points to a deleted member, the LRU victim selection logic is triggered to re-start the victim selection process.

Abstract: A method and apparatus for preventing selection of Deleted (D) members as an LRU victim during LRU victim selection. During each cache access targeting the particular congruence class, the deleted cache line is identified from information in the cache directory. A location of a deleted cache line is pipelined through the cache architecture during LRU victim selection. The information is latched and then passed to MRU vector generation logic. An MRU vector is generated and passed to the MRU update logic, which is selects/tags the deleted member as a MRU member. The make MRU operation affects only the lower level LRU state bits arranged in a tree-based structure state bits so that the make MRU operation only negates selection of the specific member in the D state, without affecting LRU victim selection of the other members.

Abstract: A method and apparatus for enabling protection of a particular member of a cache during LRU victim selection. LRU state array includes additional “protection” bits in addition to the state bits. The protection bits serve as a pointer to identify the location of the member of the congruence class that is to be protected. A protected member is not removed from the cache during standard LRU victim selection, unless that member is invalid. The protection bits are pipelined to MRU update logic, where they are used to generate an MRU vector. The particular member identified by the MRU vector (and pointer) is protected from selection as the next LRU victim, unless the member is Invalid. The make MRU operation affects only the lower level LRU state bits arranged a tree-based structure and thus only negates the selection of the protected member, without affecting LRU victim selection of the other members.

Abstract: According to one embodiment of the present invention, a method of establishing a digital certificate on an endpoint includes establishing a connection between a proxy function module and the endpoint. The proxy function module is remotely located from the endpoint and operable to communicate with the endpoint and a certificate authority. Authentication information is generated at the endpoint. A portion of the authentication information is transmitted to the proxy function module. The proxy function module obtains a digital certificate based on the portion of the authentication information. The digital certificate is received at the endpoint from the proxy function module.

Abstract: According to one embodiment of the present invention, a method of updating a certificate trust list on a first endpoint includes receiving an initial certificate trust list at the first endpoint. The initial certificate trust list includes authentication data for at least a second endpoint. Digitally signed information is received at the first endpoint and authentication is initiated against the authentication data for the at least a second endpoint. The authentication occurs only if the digital signature is complementary to the authentication data for the at least a second endpoint. After successful authentication, the initial certificate trust list is updated with the information to yield an updated certificate trust list.

Abstract: The present invention is contemplates an automatic, secure AP configuration protocol. Public/private keys and public key (PK) methods are used to automatically establish a mutual trust relationship and a secure channel between an AP and at least one configuration server. An AP automatically forwards a location identifier to the configuration server, and the configuration server delivers common, AP specific, and location specific configuration parameters to the AP.

Abstract: A technique and associated software for spatially coordinating, storing, and manipulating computer aided Design (CAD) files with a master dimensional plan (MDP) file (FIG. 1, MPD File, Plan, Electrical, Structural, etc.). The plan, elevation, section, and other related files are coordinated to a single unified spatial layout referenced to the MDP file. Special “tools” are used to design, manipulate and present the information as two-dimensional drawings referenced in the working space to the MDF file. Moving between the CAD drawing files coordinated to the MDP is facilitated by using icons corresponding to standard architectural graphic symbols as switch file icons that switch the user to other view files of the displayed object based on the selected graphic symbol. The technique allows the user who is familiar with standard architectural nomenclature to move through CAD drawing files without needing to know the underlying CAD file structure.

Abstract: An apparatus is provided that includes a dedicated appliance operable to interface with a computing platform. A provisioning process may be initiated such that the dedicated appliance responds by monitoring a port for a connection request from the computing platform. Upon receiving the connection request the dedicated appliance completing a connection and generates a random numeric or an alphanumeric string, the dedicated appliance calculating a key derived from the random numeric string or the alphanumeric string using a key derivation process. The dedicated appliance waits for the credential packet from the computing platform before establishing a secure connection between the dedicated appliance and the computing platform.

Abstract: A method and processor chip design for enabling a processor core to continue sending store operations speculatively to the store queue after the core receives indication that the store queue is full. The processor core is configured with speculative store logic that enables the processor core to continue issuing store operations while the store queue full signal is asserted. A copy of the speculatively issued store operation is placed within a speculative store buffer. The core waits for a signal from the store queue indicating the store operation was accepted into the store queue. When the speculatively-issued store operation is accepted within the store queue, the copy is discarded from the buffer. However, when the store operation is rejected, the speculative store logic re-issues the store operation ahead of normal store operations.

Abstract: An interface that couples a surface coil array having N receiving elements to an NMR scanner having M preamplifier inputs. The interface includes an RF switch array and a transmit/receive bias circuit. The RF switch array and the transmit/receive bias circuit are controlled by a control logic circuit. In response to a predetermined input, the control logic circuit causes a predetermined subset of the N receiving elements to be couple to the preamplifier inputs of the NMR scanner. Preferably, N may be larger than M.

Abstract: A system for receiving effluent from an apparatus, for example, a sterilizer, sterilizer unit or sterilizer system, or other device(s), that initially determines the temperature of the effluent. If the effluent temperature is such that the effluent is “hot”, the effluent it is not suitable for reuse, and the effluent is sent to be tempered, such that it cold enough to be released into a drain, whereby it will not damage the drain. If the effluent temperature is such that the effluent is “cold”, the effluent is suitable for reuse and therefore, will be recirculated to the device. The effluent moves into a holding tank, where it combines with water, and is pumped to the apparatus.
