Publication number: 20100287402Abstract: A timestamping apparatus and method are provided. The timestamping apparatus implements timestamping on a synchronization message at a physical layer when the synchronization message is transmitted to the physical layer. At an application layer of the timestamping apparatus, a bit stream including a start indicator bit informing a start of a pseudo random number sequence, the pseudo random number sequence, and an end indicator bit informing an end of the pseudo random number sequence is generated to check whether or not a message received from the physical layer is the synchronization message, and is inserted as signature information of the synchronization message. At the physical layer of the timestamping apparatus, the signature information included in the synchronization message is detected, and timestamping information is generated when the signature information is detected.Type: ApplicationFiled: May 10, 2010Publication date: November 11, 2010Applicants: Electronics and Telecommunications Research Institute, Korea Advanced Institute of Science and TechnologyInventors: Seung-Hwan KIM, Kwang-Joon Kim, June-Koo Rhee, Kyu-Sang Lee, Chan-Kyun Lee, Seong-Jin Lim

Patent number: 5947267Abstract: A switch assembly which has a mount (12), an elongate member (14), a switch (16) and a fulcrum (18). Pressing on elongate member (14) provides a force to actuate switch (16). Elongate member (14) is resilient or, alternatively, is resiliently biased to return to an unactuated position. Fulcrum (18) is movable along a length of elongate member (14). Positions of fulcrum (18) along the length enables variation of the force to actuate switch (16). As a result of this variation, different tactile feel of the switch assembly can be provided depending on position of fulcrum (18) relative to switch (16). Fulcrum (18) can also be positioned along elongate member (14) to provide a locking position that prevents switch (16) from being actuated.Type: GrantFiled: November 21, 1997Date of Patent: September 7, 1999Assignee: Motorola, Inc.Inventors: Cheah Chan Kee, Seong Jin Lim, Hari Narayanan S/o P.
