Patent number: 7548851Abstract: A musical jukebox is disclosed which provides for: fast archiving of songs; a flexible user interface; easy and convenient entry of, access to and/or display of data relating to songs archived by the jukebox; easy and convenient search and locate capabilities for locating, reviewing, retrieving and/or playing songs stored in the jukebox; and low cost relative to the functionality, features, conveniences and user-friendliness provided by the jukebox. Fast of flush archiving of songs (as well as other data and signals) is accomplished by first saving sets of data without compression, which allows the data to be entered quickly, and then, compressing later at an appropriate time. A unique MP3 bit allocation encoding scheme is used to compress data. A unique memory allocation supports fast data archiving. The user interface employs two-way communication between a remote control and the jukebox. A searchable song database is structured to enable very fast searching by music category, and also by title and artist.Type: GrantFiled: October 11, 2000Date of Patent: June 16, 2009Inventors: Jack Lau, Chi Ying Tsui, Roger Shu Kwan Cheng, Chi Wai Yung, Jimmy Tai Kwan Tang, Kin Ping Ng, Sai Kit Lai, Kai Kin Chan, Wing Chau Chan

Patent number: 5514899Abstract: A magnetometer or magnetic field sensor includes semiconductor material deposited laterally on an insulating substrate. The semiconductor material is alternating regions of n- and p-type silicon provided with two cathodes, an anode and a triggering node. Upon application of a triggering pulse to a switch on the sensor, a carrier domain is formed. In the presence of a magnetic field this carrier domain is deflected to one side thus causing an imbalance in the current collected at the two cathodes.Type: GrantFiled: May 11, 1994Date of Patent: May 7, 1996Assignees: Hong Kong University of Science and Technology, R and D Corporation LimitedInventors: Jack Lau, Christopher C.

Patent number: 5146159Abstract: A tri-state pin driver is formed in part, along with a pin sensor, on an integrated circuit. A pin driver and sensor are coupled to a common pin of a device under test. In normal mode, the pin driver drives a test signal. In high impedance mode, the pin driver is at a high impedance, enabling a sensor to monitor a response signal. The pin driver includes a driver stage formed off-chip by a pair of power transistors operated in the active region. The large power transistors enable a large current (i.e., +/-500 mA) to be sourced or sunk so as to drive a device under test and back-drive preceding circuits. Operating in the active region enables faster logic state transition times, and thus, a fast test rate, while reducing undesirable signal distortion. A predriver stage is configured as a unity-gain emitter follower. The predriver stage includes first and second signal paths. Each signal path includes a pair of transistors configured, during normal mode, as a transmission gate.Type: GrantFiled: February 1, 1991Date of Patent: September 8, 1992Assignee: Schlumberger Technologies, Inc.Inventors: Jack Lau, Armagan A.
