Appl. No.:

09/656529

Assignee:

Maxtor Corporation - Longmont CO

International Classification:

G06F 1336

US Classification:

711147, 151158, 151112

Abstract:

A method and system of providing access to a shared memory interconnected to a first controller and a second controller via a bus, the bus having control signals associated therewith for data transfer control and communication between the first and the second controllers. The second controller transmits an access request to the first controller for control of the bus to access the memory. The first controller selectively grants the access request and transmits an acknowledge to the second controller; and upon receiving the acknowledge, the second controller accesses the memory for data transfer. The first controller has a first priority for accessing the memory, and the second controller has a second priority for accessing the memory, the second priority being lower than the first priority such that upon request the first controller selectively grants control of the bus to the second controller for memory access, otherwise the first controller maintains control of the bus for memory access. In one embodiment, the second controller transmits an access request to the first controller for control of the bus to access the memory; and in response, the first controller selectively grants the access request and transmits an acknowledge to the second controller. Each of the controllers relinquishes control of the bus by placing the bus in tristate, wherein the relinquishing controller stops driving the bus.

International Classification:

G01R031/08

US Classification:

324522

Abstract:

Envelope detector and method for determining whether the level of a differential input signal DPIN−DNIN is above a reference voltage V. The differential input signal is converted to a differential current IDP−IDN, the reference voltage is converted to a reference current I, the currents are compared to determine if |IDP−IDN| is greater than I, and a valid differential signal is indicated when |IDP−IDN| is greater than I.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30

US Classification:

707202, 714 20

Abstract:

A log list comprising log identifiers is received, wherein the log list delineates a set of logs to be groomed. A log sequence number and a time-stamp are extracted from the first log record of each log in the set of logs. A system ID is extracted from a log record of each log in the set of logs. An appended log list is created wherein the system ID, time-stamp and log sequence number comprise appended information that is logically appended to each of respective ones of the log identifiers. The appended log list is sorted utilizing at least a portion of the appended information, the result comprising a sorted appended log list. An actual log sequence number is extracted from the last log record of each log in the set of logs. Each of the actual log sequence numbers is compared to a corresponding predicted log sequence number, wherein the corresponding predicted log sequence number is computed utilizing the sorted appended log list. A report is generated wherein range information reflecting all discrepancies between the actual log sequence numbers and the corresponding predicted log sequence numbers are disclosed.

Abstract:

A user command communicating at least one log record search key is received from a user. A first set of one or more log records matching the log record search key is retrieved. Utilizing one or more fields from these log records, additional search criteria is dynamically composed. A second set of one or more log records matching the additional search criteria is retrieved from the DBMS log file wherein this second set of log records is logically related to the first set of log records and wherein the second set of log records is void of the log record search key. A log retrieval routine or tool deploying the above method is hereinafter referred to as a “self-learning log retrieval tool”.

Trung Van Nguyen - San Jose CA, US

Assignee:

inTEST Corporation - Cherry Hill NJ

International Classification:

G01R 31/02
G01R 1/073

US Classification:

3241581, 324754, 324761

Abstract:

An apparatus for interfacing a test head to a peripheral system is provided. The apparatus includes a first unit having a first connection member for providing electrical communication with the peripheral system, a second unit having a second connection member for providing electrical communication with the test system, and pivot members coupling the first unit and the second unit. The pivot members enable motion in the following sequence as one of the first and second unit moves towards the other: a) pivotal motion between the first connection member and the second connection member; and b) linear motion which decreases linear distance between the first connection member and the second connection member while maintaining respective contact surfaces of the first and second connection members in parallel.
