Publication number: 20100093198Abstract: A safety protection structure for universal sockets, comprising: a second module; a second slant to contact the second pin of a 3-pin plug; a sliding chute configured in parallel to the movement direction of the second module; a third module; a third slant to contact the third pin of a 3-pin plug, and matching the sliding chute of the second module. The sliding chute is configured to ensure that the third and the second module are relatively independent and movable. The second module and third module are respectively configured with a surface area to block the second pin and third pin of the 3-pin plug at the same time. In this configuration, the insulation board is closed when the pin of the plug is inserted incorrectly preventing the pin from contacting the conducting plate in the socket, and the insulation boards in the jacks not inserted with the pins remain closed.Type: ApplicationFiled: October 10, 2008Publication date: April 15, 2010Inventor: Hing Wai Michael Ma

Patent number: 7661992Abstract: A safe power plugging mechanism is configured on a power base with a pivot joint, wherein a male plug with conducting plates at its inside is configured on the pivot joint and is electrically connected with the pivot joint. A half-tile-shaped insulating tile configured outside the pivot joint axis is integral with the enclosure of the male plug, and partly encloses the pivot joint axis. A power connection plate is configured inside the power base to electrically connect the conducting plates of the male plug when the male plug is turned to a specific angle. The safe plugging mechanism also includes a female plug, which is configured at its inside with two conducting poles fitting the conducting plates of the male plug. The safe power plugging mechanism adopts a method of electric connection through a pivot joint axis which maintains connection at a specific angle and insulation at other angles.Type: GrantFiled: December 16, 2008Date of Patent: February 16, 2010Assignee: Cord-It LimitedInventor: Hing Wai Michael Ma

Patent number: 7197550Abstract: Data is received by a service provider that is indicative of a selected server-side system and a selected client-side system between which a VPN is to be established. Security settings are then automatically determined for the client-side system based at least partially on the data. The security settings are preferably public and private keys and/or a Digital Certificate. VPN configuration details, including the security settings, are then automatically transmitted to the client-side system. The client side system then uses the configuration details to automatically configure itself to establish a secure VPN tunnel between the server-side system and itself. VPN configuration details may also be automatically transmitted to a VPN concentrator within the server-side system. A Virtual Private Network tunnel is subsequently established between the client-side system and the server-side system, and the tunnel's operation verified. A computer program product for configuring a VPN system is also provided.Type: GrantFiled: August 23, 2001Date of Patent: March 27, 2007Assignee: The DirecTV Group, Inc.Inventors: Douglas A. Cheline, Michael Ma, Ye Zhang, Lester J. Chong

Publication number: 20060271707Abstract: A host name query is received by a modem from a client computer. The host name query is simultaneously transmitted from the modem to a plurality of Domain Name System (DNS) servers. A response is returned to the client computer from the modem, where the response is based on the host name query and any responses received from the DNS servers. In a preferred embodiment at least one address associated with the host name query is acquired from the DNS servers. The client computer then sends a request for content to the address. If more than one address is returned, all but one of the addresses is eliminated. This can be done by rejecting all but the most recent address, or rejecting all addresses not provided by a service provider DSN server.Type: ApplicationFiled: June 26, 2006Publication date: November 30, 2006Inventors: Douglas Cheline, Michael Ma, Ye Zhang, Lester Chong

Patent number: 6547939Abstract: A vacuum chamber deposits thin films on a substrate by sputtering a target. The beam of atoms or ions from the target is partially blocked by a shadow or adjustable uniformity mask, reducing the deposition rate onto the substrate. The adjustable uniformity mask has several adjustable fingers. The fingers extend or retract to enlarge or reduce the size of the mask. Each finger covers a different annular region or radius of the substrate. The deposition rate at different substrate radii is thus adjustable by the fingers. Several optical beams monitor the film transmittance at different substrate radii. A transmittance profile is continually generated during deposition. As deposition proceeds, radii with a thicker film have their fingers extended to reduce their deposition rate, producing a more uniform film thickness across all radii. Motors extend or retract the individual fingers.Type: GrantFiled: March 29, 2001Date of Patent: April 15, 2003Assignee: Super Light Wave Corp.Inventors: Paul Hsueh, Shyang Chang, Hans Schiesser, Michael Ma, Jack Hsu, Abraham C.

Publication number: 20030055990Abstract: A request is received to establish a VPN session with a server-side system from at least one client computer out of a plurality of client computers coupled to a modem within a client-side system. The request contains login details for a user of the at least one client computer. A network address, such as an IP (Internet Protocol) or MAC (Media Access Control) address of the at least one client computer is then determined. The user is authenticated based on the user login details, and a VPN tunnel is established over the modem between the at least one client computer having the network address and the server-side system. The same method is then used for the remainder of the plurality of client computers coupled to the modem within the client-side system.Type: ApplicationFiled: August 23, 2001Publication date: March 20, 2003Applicant: Hughes Electronics Corporation,Inventors: Douglas A.

Patent number: 5495006Abstract: The herpes simplex virus encodes ICP4, a DNA binding protein. ICP4-binding duplexed structures having significantly enhanced stability under physiological conditions are described. The structures are provided in the form of polynucleotide conjugates capable of adopting a duplexed structure, in which annealable polynucleotide strands are coupled covalently at one or both ends through a chemical linker which establishes a stabilizing bridge between strands. The present polynucleotide conjugates have therapeutic utility against viral infection as the polynucleotide strands thereof define a binding site for a viral regulatory protein, thereby inactivating the protein and preventing viral replication from occurring.Type: GrantFiled: March 1, 1993Date of Patent: February 27, 1996Assignee: Allelix Biopharmaceuticals, Inc.Inventors: Shane Climie, Michael Ma
