摘要:
An approach is provided that, upon receiving a keyboard event, reduces a volume of an audio input channel from a first volume level to a lower volume level. After the volume of the audio input channel is reduced, the approach waits until a system event occurs, with the system event based at least in part on the occurrence of a nondeterministic event. The volume of the audio input channel is then increased from the lower volume level to a higher volume level when the system event occurs

A method and apparatus for switching optical signals within an optoelectric computer network is disclosed. The optoelectric computer network includes multiple computers. Each of the computers includes a first fiber optic cable for sending optical signal beams and a second fiber optic cable for receiving optical signal beams. In accordance with a preferred embodiment of the present invention, an apparatus for broadcasting optical signals within the optoelectric computer network includes a prism and a mirror array. The prism is capable of splitting an optical signal beam from a first fiber optic cable of one of the computers into multiple optical signal beams. Each of the optical signal beams is of an unique frequency within a light spectrum. The mirror array, which is formed by an array of deformable mirrors, then individually directs each of the optical signal beams to a respective second fiber optic cable of the rest of the computers.

A system and method for improved scroll mouse operation is presented. A user operates a computer mouse, which includes a scroll ring that functions as a middle mouse button. During operation, the user configures a scroll suppression manager to discard a particular number of scroll commands when the user moves the computer mouse's scroll ring. The user specifies a number of scroll commands to discard when the computer mouse's pointer location is positioned over particular mouse-over conditions, such as a web page link or a drop down menu. Once the scroll suppression manager has discarded the user-specified number of scroll commands, the scroll suppression manager processes subsequent scroll commands until the user stops scrolling or the user selects an object on the user's computer screen.

A method and apparatus for aligning surface mounted optoelectric devices on a printed circuit board are disclosed. An optical transmitter and an optical receiver are added to the surface mounted optoelectric device. Also, a fiber optic cable is embedded within a printed circuit board. The length of the fiber optic cable is at least equivalent to a distance between the optical transmitter and the optical receiver placed on the surface mounted optoelectric device. An orientation of the surface mounted optoelectric device is aligned on the printed circuit board such that an optical signal transmitting from the optical transmitter can be received by the optical receiver via the fiber optic cable.

An extended PCI bus (100) accepts both standard 33 MHz (101-102) and extended 66 MHz (103-104) PCI I/O devices, and permits the intermixing and interoperability of both types of devices on the same bus. Each extended 66 MHz initiator device (103) includes a target memory (205) that is programmed at boot up to include a list of address ranges of all extended 66 MHz devices. Each extended 66 MHz device includes a clock multiplier (202) that generates an internal 66 MHz clock signal by doubling the 33 MHz bus clock frequency. This clock multiplier may be in the form of a simple edge detecting frequency doubler (FIG. 4), or a phase locked loop (FIG. 5) that can also provide for phase adjustments to alter the skew between the bus and internal clocks. To transfer data between two extended 66 MHz devices, an extended initiator device sends, during the address/control phase of the bus cycle, a fast read or write command to the extended target device over the C/BE lines of the bus. Subsequently during the data phase of the bus cycle, data is transferred over the bus at the 66 MHz rate using the 66 MHz internal clock signals.

A printed circuit board for coupling surface mounted optoelectric semiconductor devices within a computer system is disclosed. The printed circuit board includes at least one substantially planar surface. There are multiple electrically conductive sites located on the substantially planar surface for connection to a surface mounted semiconductor electronic device. The electrically conductive sites are also connected to electrical interconnects embedded within the printed circuit board. In addition, there are multiple optical pathways terminated at the substantially planar surface for coupling a surface mounted semiconductor optoelectric device.

A Level Sensitive Scan Design (LSSD) Shift Register Latch pair implemented in current switch logic is disclosed. The arrangement is characterized by the logic used to control the L1 and L2 latches being implemented in Differential Cascode Current Switch logic and the L1/L2 latches being coupled to only one current source. A "merged" L1/L2 latch arrangement employing only one current source is provided for an LSSD testing environment.
