Title: Digital chrominance signal processing circuit
Inventor: TONAMI JUNICHIRO
IPC: H04N9/83
Filed: 1994-06-28
Granted: 1995-03-11
Abstract: A reproducing circuit converts a low-band converted chrominance signal into digital signals for reproducing processing and outputs a high-band converted chrominance signal. In this reproducing circuit, the digitalized low-band chrominance signal is separated to phase data and amplitude data. The phase data is decoded, and the frequency and phase fluctuations thereof are corrected. The corrected phase data is encoded to generate a continuous wave. The generated continuous wave is multiplied by the amplitude data to obtain the high-band converted chrominance signal. Similarly, a recording circuit converts a high-band converted chrominance signal into digital signals for recording processing and outputs a low-band converted chrominance signal. In this recording circuit, the digitalized high-band chrominance signal is separated to phase data and amplitude data. The phase data is decoded, and the frequency and phase fluctuations thereof are corrected. The corrected phase data is encoded, and the frequency thereof is controlled to a predetermined frequency to generate a continuous wave. The generated continuous wave is multiplied by the amplitude data to obtain the low-band converted chrominance signal.

Title: High performance symmetric arbitration protocol with support for I/O requirements
Inventor: SARANGDHAR NITIN V
IPC: H04L12/403
Filed: 1994-08-05
Granted: 2000-08-01
Abstract: A system and method for providing a high performance symmetric arbitration protocol that includes support for priority agents. The bus arbitration protocol supports two classes of bus agents: symmetric agents and priority agents. The symmetric agents support fair, distributed arbitration using a round-robin algorithm. Each symmetric agent has a unique Agent ID assigned at reset. The algorithm arranges the symmetric agents in a circular order of priority.  Each symmetric agent also maintains a bus ownership state of busy or idle and a Rotating ID that reflects the symmetric agent with the lowest priority in the next arbitration event. On an arbitration event, the symmetric agent with the highest priority becomes the symmetric owner. However, the symmetric owner is not necessarily the overall bus owner (i.e., a priority agent may be the overall bus owner). The symmetric owner is allowed to take ownership of the bus and issue a transaction on the bus provided no other action of higher priority is preventing the use of the bus. A symmetric owner can maintain ownership without re-arbitrating if the transaction is either a bus-locked or a burst access transaction. The priority agent(s) has higher priority than the symmetric owner. Once the priority agent arbitrates for the bus, it prevents the  symmetric owner from issuing any new transactions on the bus unless the new transaction is part of an ongoing bus-locked operation.

Granted: 1999-11-01
Abstract: An audio system includes a light sensitive switch connected to a microphone. Activation of the microphone operates the switch, thereby indicating that the microphone is in use. As the user turns the microphone on, a voltage is applied across a light emitting diode which causes the diode to emit light.

Title: Portable loudspeaker/directional microphone peripheral
Inventor: Christopher t welsh
IPC: H04R1/02
Filed: 1996-09-16
Granted: 1997-04-11
Abstract: A loudspeaker system which can be utilized with laptop PCs employs a loudspeaker enclosure having a unique shape which is easily mounted to the back of a display of the laptop PC and also provides sufficient compliant air volume to yield high quality sound. More specifically, the higher quality sound and ease of mounting is realized by employing a loudspeaker enclosure which is in the form of an "L-shape". This allows one leg of the L-shaped enclosure to be employed to attach the loudspeaker, for example, to the back of the laptop PC display unit and allows the speaker portion that is visible to be of minimal size. Additionally, the "L-shaped" loudspeaker enclosure, in addition to providing the desired compliant air volume for quality sound, also allows for the majority of the loudspeaker enclosure to be hidden from the view of a laptop PC user and, therefore, is more aesthetically pleasing to the user.
