Publication number: 20170048855Abstract: Methods and devices are disclosed for enabling improved service acquisition on at least one SIM of a wireless communication device. After a first SIM has lost service, the wireless communication device may identify, in a first radio access technology (RAT) priority list configured to support the first SIM, a highest ranked radio access technology. The wireless communication device may search a local wireless environment for networks associated with the identified radio access technology, and determine whether any network associated with the identified radio access technology is available, Upon determining that the no network associated with the identified radio access technology is available, the wireless communication device may update the RAT priority list associated with the first SIM.Type: ApplicationFiled: August 12, 2015Publication date: February 16, 2017Inventors: Vinay Garg, Shivank Nayak, Brian Patrick A'Hearn

Publication number: 20050246021Abstract: A high strength porous polymeric material manufactured by a compression process is disclosed. The material results in a network of interconnected collapsed pores, which forces thin overlapping walls and passages to be created. The network provides permeable access for fluid migration throughout the material. The strength and/or permeability are advantageous for medical devices and implants.Type: ApplicationFiled: April 29, 2004Publication date: November 3, 2005Inventors: Timothy Ringeisen, Amanda Turner, Joseph DeMeo, Patrick Hearn, Robert McDade

Publication number: 20050182411Abstract: A device is formed by the process into a bone screw or fastener, wherein the head has a degree of polymer alignment and strength, and wherein the shank has a higher degree of polymer alignment and strength. In practice of the present invention, the polymer slug is pressed into the die cavity by the actuation of ram press, causing the slug to conform to the die cavity. Through this process, the polymer molecular orientation is aligned to different degrees, in different zones of the device.Type: ApplicationFiled: February 17, 2004Publication date: August 18, 2005Inventors: Joseph DeMeo, Patrick Hearn, Robert McDade

Patent number: 6567235Abstract: A drive housing (24) including a housing cover wall (56), a housing base wall (53) having at least one wall aperture (32), and one or more housing side walls (54) that secure the housing base wall (53) to the housing cover wall (56). The drive housing (24) also includes at least one connector (28) that carries electrical signals through the drive housing (24). Each connector (28) extends through a corresponding wall aperture (32). The drive housing (24) also includes a sealer (30) that seals each connector (28) to the housing base wall (53). The housing base wall (53) has a wall coefficient of thermal expansion, and the sealer (30) has a sealer coefficient of thermal expansion. Preferably, the wall coefficient of thermal expansion is substantially similar to the sealer coefficient of thermal expansion. As a consequence, leakage of gas through the drive housing (24) of the disk drive (10) is significantly reduced.Type: GrantFiled: March 29, 2001Date of Patent: May 20, 2003Assignee: Maxtor CorporationInventors: Kumaraswamy Kasetty, Thomas Andrikowich, Patrick Hearn

Patent number: 6556372Abstract: Hermetic seals that maintain a data storage device atmosphere enable the use of alternate atmospheres to reduce the aerodynamic drag and turbulent excitation within the head/disk assembly (HDA). A metallic seal having a base layer and a plating layer is compressed between the data storage device cover and base such that the plating layer fills surface asperities of the cover and base to create a hermetic seal therein between. Alternatively, the data storage device is encased inside a metallic can formed by seam sealing two housings together. Alternatively, an epoxy seam is dispensed around the periphery of the data storage device base to seal the cover thereon. An O-ring acts as a barrier to isolate the epoxy from the HDA atmosphere.Type: GrantFiled: March 11, 2002Date of Patent: April 29, 2003Assignee: Maxtor CorporationInventors: Patrick Hearn, Kumaraswamy Kasetty

Patent number: 5216655Abstract: In the manufacture of a high capacity data storage device having multiple surfaces for recording information, the yield of the manufacturing process is improved by providing the storage device with a spare surface. If a recording surface is found to be totally defective, or, substantially worse than the other surfaces, as determined by the manufacturing testing procedures, that surface is, by means of a remapping table, logically retired and the information intended for the defective surface is stored on the logically reallocated spare surface.Type: GrantFiled: June 26, 1991Date of Patent: June 1, 1993Assignee: Digital Equipment CorporationInventors: Patrick Hearn, Fernando A. Zayas, Antonios E. Prentakis, William D. Lewis
