Patent number: 8848548Abstract: Aspects describe utilizing the Internet capability in mobile devices/networks to deliver broadcast multimedia to a device. The broadcast can be video, audio, and so forth. Initially the broadcast multimedia is transmitted at high data rates (and in unicast mode) in order for a buffer associated with mobile device to be built to a very long buffer length. When the long buffer length is reached, the multimedia can be delivered at real-time rates. The multimedia delivered at real times rates can be unicast mode or in multicast mode. If the buffer is depleted, a mobile device that is part of a multicast group can autonomously disassociated from the group until the buffer length is restored.Type: GrantFiled: August 4, 2009Date of Patent: September 30, 2014Assignee: QUALCOMM IncorporatedInventors: Ahmad Jalali, Leonard N.

Publication number: 20080250828Abstract: An ignition key switch mechanism for a vehicle having an automatic or semi-automatic gearbox comprises two solenoids and arranged at right angles to each other between which a slider or lever is disposed. The mechanism locks to prevent turning of the ignition key to the off position and removal of the key. Locking is effected by activating one solenoid to pull the shaft of that solenoid inside the armature of the solenoid. That in turn pulls the slider towards the solenoid and enables a locking pin on the slider to lock the mechanism. As the slider moves toward the solenoid a notch in the slider is brought into line with the shaft of the second solenoid. This shaft enters the notch under spring force to hold the mechanism in the locked position. Unlocking is effected by activating the second solenoid to withdraw the shaft from the notch allowing the first solenoid and the locking pin to return to unlocked positions which in turn permits the key to be turned to the off position and removed.Type: ApplicationFiled: September 27, 2005Publication date: October 16, 2008Inventor: Brian Bugeja

Closure for doors, bonnets, tailgates or the like, in particular of vehicles, such as motor vehicles
Patent number: 6098432Abstract: The invention concerns a closure with a closure cylinder whose cylinder core (33) can be moved by a key into different operating positions. The object of the invention is for at least one microswitch (50) to be actuated by switching cams (42) only once, even if the switching cam (42) continues to be moved when the microswitch (50) has been actuated. During the return movement, this microswitch (50) should not be triggered by the switching cam (42) again, and so faulty switching is avoided. To that end, a control member (40) cooperates via a separable coupling (35, 45) with a control member (40) on which the switching cam (42) is located. The control member (40) is acted upon by a restoring spring (46) which endeavors to move the control member into an initial position and simultaneously subject it to a force (43) in the coupling sense by the cylinder core (33).Type: GrantFiled: December 28, 1998Date of Patent: August 8, 2000Assignee: Huf Hulsbeck & Furst GmbH & Co.
