12/742591

Inventors:

Ivan Vecerina - Lausanne, CH
Vinh Pham - Rancho Santa Margarita CA, US

Assignee:

Biosensors International Group, Ltd. - Hamilton

International Classification:

B05C 11/00
B05C 13/00
G01P 3/36
A61L 33/00
B05D 3/00

US Classification:

Abstract:

An automated apparatus and method for coating medical devices such as an intravascular stent, are disclosed in the method, a 2-D image of a stent is processed to determine (1) paths along the stent skeletal elements by which a stent secured to a rotating support element can be traversed by a dispenser head whose relative motion with respect to the support element is along the support-element axis, such that some or all of the stent skeletal elements will be traversed (2) the relative speeds of the dispenser head and support element as the dispenser head travels along the paths, and (3), and positions of the dispenser head with respect to a centerline of the stent elements as the dispenser head travels along such paths The rotational speed of the support and relative linear speed of the dispenser are controlled to achieve the desired coating thickness and coating coverage on the upper surfaces, and optionally, the side surfaces, of the stent elements.

US Classification:

705 271, 715764, 707E17109, 705 267

Abstract:

A system and method for providing a listing activity engine for online computer users is disclosed. A particular embodiment includes: accessing a plurality of listings corresponding to items offered on a host site; accessing listing activity level information related to the plurality of listings, the listing activity level information including information indicative of a number of times particular listings of the plurality of listings were viewed or activated; producing search results that include only matched listings of the plurality of listings that were viewed or activated a number of times less than a pre-determined listing activity threshold; and displaying the search results to a user.

Inventors:

VINH HUY PHAM - San Jose CA, US

International Classification:

G06F 3/0488
H04L 29/08
G06F 3/0481

Abstract:

A method of connecting users and profiles, each user has a point amount and each profile has a point threshold. The method comprises comparing a user's point amount with the point threshold of a profile, presenting a user interface control associated with the profile according to a result of the comparison, detecting a gesture associated with the interface control, and creating a connection between the user and the profile in response to the gesture.
