Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 1300

US Classification:

710100

Abstract:

An on line serviceable computing system employing a small computer system interface (SCSI) bus architecture connecting two host computers to at least one additional shared device including a termination adapter circuit that can sense when a SCSI termination at the end of the SCSI bus is lost and automatically switch in a new SCSI bus termination to thereby ensure that the bus is terminated at both ends as required for continuous operation.

11/552107

Inventors:

David L. Griffith - Fremont CA, US
Michel P. Cekleov - Mountain View CA, US

Assignee:

3Par, Inc. - Fremont CA

International Classification:

G11C 7/00

US Classification:

365193, 3652331

Abstract:

A memory controller includes a gate circuit gating a data strobe signal from a memory device, a delay circuit delaying the data strobe signal from the gate circuit, a read buffer capturing values of a data signal from the memory device in response to the data strobe signal, a cumulative strobe counter incrementing a detected strobe count by the number of edges detected in the data strobe signal, and a control logic controlling the gate circuit and receiving the detected strobe count from the strobe counter. The control logic enables and disables the gate circuit after the start of a preamble and before the end of a postamble in the data strobe signal, respectively. When the memory controller is not expecting the data strobe signal from the memory device, the control logic compares the detected and the expected strobe counts and reports a strobe error when they do not match.

G11B 1700

US Classification:

364900

Abstract:

A velocity control apparatus for a disk drive of the type comprising a recording disk rotatable about its axis, an electromagnetic read/write head for reading data from and writing data onto tracks on a surface of the disk, and means coupled to the head and responsive to velocity command signals for controlling the direction and speed of movement of the head. The velocity control apparatus includes a memory divided into a plurality of sections respectively associated with different ranges of desired distances to be traveled by the head, each section containing a predetermined number of addressable storage locations together defining an approximation of a desired velocity trajectory curve for a desired distance to be traveled included within the range associated with said section.

G06F 1308

US Classification:

364900

Abstract:

A disk drive comprises a housing having a door through which a cartridge including a recording disk therein may be inserted. A spindle drive assembly is mounted in the housing and is responsive to a first set of instructions for rotating the recording disk of a disk cartridge loaded into the housing through the door and onto the spindle drive assembly. An actuator is also mounted in the housing and is capable of controlled reciprocal movements relative to the axis of rotation of the spindle drive assembly. A head carriage assembly is mounted in the housing to the actuator and includes at least one electromagnetic read/write head thereon for reading data from the writing data onto tracks of the recording disk of a cartridge loaded onto the spindle drive assembly. Servo control apparatus is mounted in the housing and is responsive to a second set of instructions for controlling the speed and direction of the reciprocal movements of the actuator. Additionally, read/write apparatus is mounted in the housing and is responsive to a third set of instructions for controlling the reading and writing of data by the electromagnetic head.
