Patent number: 9141145Abstract: A security apparatus for securing a portable device includes a housing having a first housing portion configured to partially surround a first portion of the portable device, and a second housing portion configured to partially surround a second portion of the portable device. The second housing portion is selectively secured to the first housing portion when the housing is engaged with the portable device. The security apparatus also includes an attachment device extending from the housing. The attachment device is configured to engage a locking head. The security apparatus further includes a modular accessory coupled to the housing. The modular accessory is connected to the housing when the first and second housing portions are secured together to surround the portable device. The modular accessory is only removable from the housing when the first and second housing portions are disconnected from the portable electronic device.Type: GrantFiled: January 20, 2014Date of Patent: September 22, 2015Assignee: ACCO Brands CorporationInventors: Ryan White, A. John Venida, Jonathan Stacey, Wilson Shu Chiu Tse

Patent number: 9014174Abstract: In some implementations, a method for routing a communication includes receiving, from an application running on a user equipment (UE), a request to access a forwarding information base (FIB). The UE includes a plurality of FIBs and a plurality of communication interfaces. Each of the plurality of FIBs includes communication interface information. An assigned FIB from the plurality of FIBs is determined. The assigned FIB has been assigned to the application. An appropriate communication interface for communication is determined based on a destination of the communication and the communication interface information of the assigned FIB. The communication is transmitted to the destination using the communication interface.Type: GrantFiled: September 27, 2012Date of Patent: April 21, 2015Assignees: BlackBerry Limited, 2236008 Ontario Inc.Inventors: Kerry Gordon Peter Williams, Nils Patrik Lahti, Chi Chiu Tse

Patent number: 8997203Abstract: In some implementations, a method for routing communication includes determining a binding interface for a communication session based on a forwarding information base (FIB) and a destination for the communication session. The communication session is from an application running on user equipment (UE), and the binding interface is included in a virtual private network (VPN) tunnel established through an Internet Protocol (IP) security (IPsec) interface. Whether to filter the communication session is determined based on which perimeter of the UE includes the binding interface and which perimeter of the UE includes the IPsec interface.Type: GrantFiled: August 7, 2012Date of Patent: March 31, 2015Assignee: BlackBerry LimitedInventors: Chi Chiu Tse, Jason Songbo Xu, Ania Halliop, Chun Hei Justin Lai

Publication number: 20150074754Abstract: Plural modes of operation may be established on a mobile device. Specific modes of operation of the mobile device may be associated with specific spaces in memory. By associating the existing certificate store structure and key store structure with a mode of operation, certificates and keys can be assigned to one space among plural spaces. Furthermore, management (viewing/importation/deletion) of certificates associated with specific modes of operation may be controlled based on the presence or absence of a mobile device administration server and the status (enabled/disabled) of an IT policy.Type: ApplicationFiled: November 18, 2014Publication date: March 12, 2015Inventors: Christopher Lyle BENDER, John Vincent STOROZUK, Alan Pak-Lun HO, Chi Chiu TSE

Publication number: 20110063093Abstract: A serialization service module is provided for configuring an asset management system to provide a secure means of generating, assigning to chips (or other electronic objects or devices), and tracking unique serial numbers. To provide this service, a controller is used to define a product model, then to define one or more serialization schemas to be bound to each product model. Each serialization schema contains a range of serial numbers for a particular product. The serial number schemas are sent over a secure, encrypted connection to appliances at the manufacturer's location. Agents can then request serial number values by product name. The serial numbers are generated by the appliance, metered, and provided to the agents. The serial numbers are then injected sequentially into each die in a chip manufacturing process using the agent.Type: ApplicationFiled: July 12, 2010Publication date: March 17, 2011Applicant: CERTICOM CORP.Inventors: Eric Fung, Brian Neill, Chi Chiu Tse

Publication number: 20090137439Abstract: The present invention generally relates to compositions and methods for cleaning by contacting a hard disk data storage device, an inkjet printer cartridge head, or the like having residue thereon, particularly organometallic or metal oxide residue, with a cleaning composition of the present invention for a time and at a temperature sufficient to remove the residue. Stirring, agitation, circulation, sonication or other techniques as are known in the art optionally may be used. The hard disk data storage device, an inkjet printer cartridge head, or the like is generally immersed in the cleaning composition. The time and temperature can be determined based on the particular material being removed from a substrate. Generally, the temperature is in the range of from about ambient or room temperature to about 100° C. and the contact time is from about 1 to about 60 minutes. The preferred temperature and time of contact for this invention is about 25 to about 45° C. for about 2 to about 60 minutes.Type: ApplicationFiled: September 29, 2008Publication date: May 28, 2009Inventors: Xuan-Dung Thi DINH, Chiu Tse, Chris Reid
