Patent number: 10056117Abstract: A unitary enclosure base for a data storage device integrally includes a first surface beneath a bottom disk, a bypass channel formed with an entry area with a lower surface below the first surface, a second surface lower than the first surface and beneath an actuator arm that services the bottom surface of the bottom disk, and a flow diverter extending upward from the first surface and positioned upstream of the actuator arm. The diverter may be positioned relative to the bypass channel such that disk-generated gas flow is diverted into the bypass channel away from the actuator arm. The base may further include a spoiler extending upward from the first surface and positioned downstream of the actuator arm. The spoiler may be positioned to inhibit a wake effect upon the actuator arm.Type: GrantFiled: May 11, 2017Date of Patent: August 21, 2018Assignee: Western Digital Technologies, Inc.Inventors: Andre S. Chan, Ta-Chang Fu, Hitoshi Shindo, Takaaki Deguchi, May Ching Kung, Myeong Eop Kim

Patent number: 7062566Abstract: An exemplary system and method for using a network access system, such as a virtual private network (VPN), are provided. A user device may have a user session with a home agent. Additionally, an initiating security gateway may be in communication with the home agent, and a terminating security gateway may be in communication with the initiating security gateway via a tunnel (e.g., Internet Protocol in Internet Protocol (IP-in-IP) or Internet Protocol security (IPsec) tunnel). Further, a virtual local area network (VLAN) tag associated with the user session may map to a selector operable in a security policy database. The selector may be used to find a security policy defining an IPsec procedure, and the security policy may be applied to the tunnel. Also, the initiating security gateway may also include a Quality of Service (QoS) module that determines QoS markings for a packet traveling along the tunnel.Type: GrantFiled: October 24, 2002Date of Patent: June 13, 2006Assignee: 3Com CorporationInventors: Satish Amara, Chandra Warrier, Ching Kung

Publication number: 20050201433Abstract: Methods and apparatus that provide TO-can optoelectronic packages suitable for optical telecommunications applications involving data speed rates of up to 10 Gbps and beyond. A TO-can optoelectronic package may comprise a TO-can cap and a TO-can header defining an interior region of the package. An optoelectronic component such as a laser or photodetector can be mounted within the interior region of the TO-can. An electrical connection may be selected for coupling the optoelectronic component to a selected post of the TO-can package. The electrical connection may include a transmission line formed from a conductive element other than a bond wire having a predefined length that can assist in reducing parasitic effects within the TO-can optoelectronic package to accommodate high-speed data rates. The transmission line itself is connected to the optoelectronic component and the selected post with a plurality of bond wires.Type: ApplicationFiled: March 18, 2005Publication date: September 15, 2005Inventors: Majid Riaziat, Ching-Kung Tzuang, Yi-Ching Pao

Publication number: 20050071273Abstract: A multilevel hierarchical feature rights management system (100) provides an efficient way of allocating feature keys. Sub-agents (140) are provisioned or activated with application software having features. The sub-agents request permissions from feature rights management agents (120) to use these features. The feature rights management agents (120) receive feature keys over a network (130) from a feature rights server (110). The feature rights management agents (120) then permit sub-agents (140) to use their provisioned features. In a further aspect of the invention the sub-agents (140) voluntarily release feature permissions rather than the server (110) or the agents (120) forcing the sub-agents (140) to revoke rights.Type: ApplicationFiled: September 25, 2003Publication date: March 31, 2005Applicant: UTSTARCOM, INC.Inventors: William Vroman, Marko Pfaff, Christian Rigg, Ching Kung, Himanshu Shekhar

Publication number: 20050071274Abstract: Permission information (110), including a security parameter index SPI and a digital signature (120), form a digital rights key (140) in a digital rights management system. The security parameter index SPI identifies and algorithm for digital signature calculation (130) and of the digital rights key (140). A digital rights source generates the digital rights key (140) using the security parameter index SPI for digital rights management of licenses to an application. A digital rights client receives the digital rights key (140) and interprets it using an algorithm identified by the security parameter index SPI.Type: ApplicationFiled: September 27, 2003Publication date: March 31, 2005Applicant: UTSTARCOM, INC.Inventors: Marko Pfaff, Christian Rigg, William Vroman, Ching Kung, Himanshu Shekhar

Patent number: 6763018Abstract: A high density network access server implements a tunneling protocol between a modem module and a route server module. PPP and routing control packets received from the PPP link are tunneled to the route server for processing. The IP data packet forwarding function for the network access server is distributed directly to the modem modules. The combination of distributed PPP processing and distributed IP data packet forwarding enables the capacity of the network access server to be scaled to orders of magnitude greater than previously known, to handle thousands or even tens of thousands of simultaneous data sessions.Type: GrantFiled: November 30, 2000Date of Patent: July 13, 2004Assignee: 3COM CorporationInventors: Sanil Kumar Puthiyandyil, Matthew H. Harper, Ching Kung, Shaji Radhakrishnan, Rajesh Ramankutty
