Filed:

Oct 23, 2006

Appl. No.:

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.

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.

International Classification:

G08B 522

US Classification:

395750

Abstract:

The invention encompasses a system that utilizes radio frequency circuitry in combination with microprocessor devices and specially designed software to provide an improved structure and operation for the monitoring, protection and control of inventory assets. Generally, the system is embodied in a system controller unit, one or more interrogator devices and multiple transponder units. The system controller unit may be a personal computer (PC) based device for effecting the control and monitoring of the system's operation. In addition, the system controller unit serves as a data collection device and as an alarm device. The interrogator device(s) incorporate a transceiver controlled by microprocessor circuitry within the interrogator devices. The transponder units also include a radio transceiver and microprocessor circuitry. The transponder units are attached to a container or item to be monitored and protected.
