Assignee:

Marvell International Ltd. - Hamilton

International Classification:

G06F 12/00

US Classification:

711167, 702 89, 36518907, 365193, 711E12017

Abstract:

A calibration system for a data storage device includes a memory and a memory control module. The memory buffers data between a host and the data storage device and generates a data strobe signal. The memory control module selectively adjusts a delay of the data strobe signal. Data is read from the memory based on the data strobe signal.

Abstract:

A calibration module for a data storage control system. The calibration system includes a programmable delay module configured to i) receive a data strobe signal, ii) receive a delay value, and iii) output a delayed data strobe signal to a buffer based on the delay value, wherein data is read from the buffer based on the delayed data strobe signal. The calibration module further includes a delay calculation module configured to calculate the delay value based on a comparison between the data strobe signal and the delayed data strobe signal.

International Classification:

G01B 9/02

US Classification:

356491, 356480

Abstract:

Techniques and devices based on transverse magnetic (TM) and transverse electric (TE) modes in an optical resonator or interferometer to provide sensitive optical detection with insensitivity to a change in temperature. A shift in a difference between a first resonance wavelength of a TE optical mode and a second resonance wavelength of a TM optical mode is measured to measure a change in a sample that is in optical interaction with the optical resonator or interferometer. For example, the detected shift can be used to measure a change in a refractive index of the sample.

International Classification:

A61F 2/06

US Classification:

623 211, 623 111

Abstract:

A heart valve delivery system is provided wherein a prosthetic valve is carried on a valve catheter inside a delivery sleeve. A step balloon protrudes from the delivery sleeve and provides a tapered surface for facilitating advancement through a body vessel. The step balloon also aids in crossing the leaflets of a native valve. After the prosthetic valve is positioned within the native valve, the delivery sleeve is retracted to expose the prosthetic valve. In one embodiment, the delivery sleeve is retracted by the use of a lead screw, which effectuates relative movement between the valve catheter and delivery sleeve. The prosthetic valve is preferably self-expandable. If necessary, the step balloon may be expanded to securely seat the prosthetic valve at the site of the native valve. The prosthetic valve is preferably coupled to the valve catheter by a plurality of flexible extension arms which allow the prosthetic valve to be collapsed after initial deployment such that the prosthetic valve may be repositioned if necessary.
