Patent number: 8358267Abstract: A handheld electronic device configured to receive text messages has a body with a front face and top and bottom portions relative to text entry use orientation of the handheld device. A display screen is located on the front face of the body. The display screen presents information to the operator of the handheld device. A microprocessor located within the device is configured to receive operator commands from user inputs located on the device and instruct commensurate changes to the display screen. A navigation row of user inputs is located on the front face of the body below the display. The navigation row of user inputs includes a multi-directional navigation tool assembly laterally flanked by a pair of conjoined, depressibly actuable input keys. Each of the inputs keys is located substantially opposite the other across the navigation tool assembly and positioned adjacent to lateral sides of the navigation tool assembly.Type: GrantFiled: September 13, 2007Date of Patent: January 22, 2013Assignee: Research In Motion LimitedInventors: Chao Carl Chen, Cortez Corley, Todd Wood, Jana Lynn Papke

Patent number: 8095965Abstract: A method and apparatus for authenticating and authorizing online transactions. An authentication cookie is transmitted to a client system. The authentication cookie includes a user encryption key and an encrypted buffer that contains user identification data and a profile code. Subsequent requests for the particular service use the authentication cookie to generate a query that includes the encrypted buffer and user identification data entered by the user. Portions of the query are encrypted using the user encryption key. Queries received at each authentication and authorization server are authenticated by reconstructing the user encryption key using information transmitted in the clear and decrypting the query using both the reconstructed user encryption key and the secret key. The user identification data entered by the user is then compared with the user identification data in the encrypted buffer for further authentication. The profile code is analyzed for determining authorization.Type: GrantFiled: January 29, 2009Date of Patent: January 10, 2012Assignee: Access Co., Ltd.Inventors: Robert Lennie, Carl Chen, Gabe Dalbec

Publication number: 20100108482Abstract: For a cell-phone or PDA, the rows of key-caps include respective light-strips, which pick up light from respective LEDs surface-mounted on the PCB. The light-strips are sandwiched between the key-caps and the key-switch actuators (whereby the light-strips move with the keys when the keys are depressed). Sockets for receiving the key-caps are co-molded to the light-strips. Sockets are provided in the resilient webs of the keys for receiving under-blocks co-molded to the light-strips.Type: ApplicationFiled: January 11, 2010Publication date: May 6, 2010Applicant: RESEARCH IN MOTION LIMITEDInventors: Chao Carl CHEN, Timothy Herbert KYOWSKI, Dennis James PENNER

Publication number: 20040048512Abstract: A quick coupler for connecting power from a wire to a cylindrical terminal of a battery includes an insulted mask having a top plate, a cylindrical wall and an open end forming an internal cavity. A metal disk and a plurality of elastic metal strips are mounted in the internal cavity. The elastic metal strips are downward extended from a periphery of the metal disk and spaced from each other. The lower section of each elastic metal strip is formed with an outward inclined section which is engaged with an inward edge formed on the interior surface at the open end of the cylindrical wall of the insulated mask. The interior surface wall of each elastic metal strip is formed with a plurality of transverse ribs for enhancing contact with the cylindrical terminal of the battery.Type: ApplicationFiled: September 11, 2002Publication date: March 11, 2004Inventor: Carl Chen

Patent number: 5716553Abstract: The disclosure relates broadly to a new class or type of electroconductive powders (ECP), designated as Polytype ECP (PECP), comprising intimate mixtures of several types of ECP powders. PECP mixtures possess a lower electrical resistivity, or a higher electroconductivity, than would be expected from the weighted average of the component ECP powders. PECP are multi-component and may contain many different types of ECP. ECP components of the PECP can be selected from at least one member of the group consisting of crystallites of tin oxide containing antimony in solid solution, crystallites of antimony-containing tin oxide with uniformly distributed amorphous silica, two dimensional networks of crystallites of antimony-containing tin oxide in a unique association with amorphous silica or silica-containing material, filler materials, metal coated powders, conventional ECP materials such as carbon, aluminum powder, among others.Type: GrantFiled: May 15, 1996Date of Patent: February 10, 1998Assignee: E.
