US Patent:

58758976, Mar 2, 1999

Filed:

Mar 31, 1997

Appl. No.:

8/838479

Inventors:

William V Duncan - Scottsdale AZ
Richard J. Barton - Tempe AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

B65D 7302

US Classification:

206714

Abstract:

A packaging system (100) protects integrated circuit devices (106) from corrosion and mechanical damage. The devices are enclosed in a reel (102) having a hub (114) in which a cavity (116) is formed for retaining a molded desiccant (118). Apertures (120) between the cavity and the devices provide a vapor path for drawing moisture from the devices. A banding strip (108) for enclosing the devices within the reel has recessed areas (142) for housing pellets of desiccant (140). The reel is placed in an inflatable envelope (50) that includes view ports (56) for reading identifying information on the reel. A vacuum is drawn and the envelope is sealed. Air cells (52) in the inflatable envelope are inflated to cushion the devices from mechanical damage during shipment.

Filed:

Dec 6, 1989

Appl. No.:

7/449367

Inventors:

William V. Duncan - Scottsdale AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

B65D 7302
A47F 104

US Classification:

206328

Abstract:

A container for holding and transporting integrated circuit devices has an integral closing element. The integral closing element is cut out from one of the walls of the container and, in its rest position, remains substantially within the cutout. In an engaged position the integral closing element is pushed into a cavity of the container to block passage of the integrated circuit devices. In the engaged position the integral closing element can either be engaged in an opening made in an opposite side of the container or else can be lodged against a shoulder formed as part of the cavity.

Appl. No.:

7/883323

Inventors:

William V. Duncan - Scottsdale AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

B65D 7300

US Classification:

2064591

Abstract:

A sealed container (10) having a plurality of compartments. A first compartment (11) has a window (15) with a transparent panel. A humidity indicator device (16) is placed within the first compartment (11). A second compartment (12) is coupled to the first compartment (11) by a plurality of environmental exchange channels (17). At least one article (27), such as plastic encapsulated electronic components, is stored in the second compartment (12). A third compartment (13) is coupled to the second compartment (12) by a plurality of moisture transport channels (20). A desiccant (31) is placed in the third compartment (13). An internal environment of the sealed container (10) is monitored by viewing the humidity indicator device (16) through the window (15).

Appl. No.:

7/561885

Inventors:

William J. Duncan - Roswell GA

Assignee:

Dornier Medical Systems, Inc. - Marietta GA

International Classification:

G09B 2330

G09B 2300
A61B 506

US Classification:

434262

Abstract:

An apparatus and method for training physicians and technicians to locate stones found in simulated human body organs, principally simulated biliary and renal calculi, and then actually fragment these calculi using ESWL. A reusable semi-anthropomorphic phantom comprises an opaque liver tissue-equivalent mass having anatomically correct simulated organ cavities associated with the midsection of a human body, principally the gall bladder and the kidney. Channels lead from the exterior of the phantom to the simulated organs. A concrement is introduced into at least one simulated organ, the channels and simulated organs are filled with a fluid-like substance, and the channels are closed with plugs. A trainee then utilizes an ultrasound or X-ray locating device to examine the phantom until the concrements are located. The coordinates of the located concrements are then utilized with a concrement destroying apparatus such as an extracorporeal shock wave lithotripter (ESWL).

Appl. No.:

8/634600

Inventors:

Clifford M. Fowler - Phoenix AZ
William V. Duncan - Scottsdale AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G01N 2760
G01R 3126

US Classification:

324456

Abstract:

An ESD sensor includes a plurality of layers of dielectric material positioned on a substrate, each having a different thickness, a first contact positioned adjacent each of the plurality of layers and a plurality of second contacts, one each positioned on each layer of the plurality of layers of dielectric material. Each different thickness of each individual layer of dielectric material is formed to provide a specific voltage at which an electrical short will occur between the first and second contacts when an ESD appears thereacross, so that the sensor provides an indication of a range of voltages.
