摘要:
A circuit and method for switching between a system's internal clock and an external synchronization clock when a stable external clock has been detected, and for switching back to operating the system using said internal clock when a predetermined number of sequential external clock pulses exceed a predetermined switching period dropout threshold or are otherwise missing.
摘要:
In a switch mode power supply, a circuit and method for switching between an internal clock and an external synchronization clock when a stable external clock has been detected, and for switching back to operating the power supply using said internal clock when a predetermined number of sequential external clock pulses exceed a predetermined switching period dropout threshold or are otherwise missing. In one embodiment, a power system comprises a plurality of power supplies connected in parallel to a common load and where each power supply is synchronized to the external clock when a stable external clock has been detected by each.

This method is a direct development method for achieving a solid state image pickup device with a high speed electronic shutter on itself. A field integrating time is divided into a useless integrating time and a useful integrating time. The shorter one is the useful integrating time, the faster one is the electronic shutter speed. The useless integrated charges are cleared by the "photographic plate" clearing method. This image pickup camera apparatus is a high speed image pickup camera apparatus having low or slight high frame frequency, short explosure. A clear, relatively still or very slowly spinning images can be obtained by adjusting the field frequency of the high speed pickup camera apparatus.

A collaboration system includes a remote server system and one or more client devices connected to the remote server system, at least one of which being a first client device that includes a touch screen display. Upon receipt of a user instruction, the collaboration system opens a document at the first client device and displays the document on the touch screen display to a first user. The collaboration system detects a first comment on the document from the first user through interacting with the touch screen display. The collaboration system receives a second comment on the document from the remote server system. The second comment is generated by a second user of a second client device and transmitted to the remote server system through a computer network. The collaboration system displays, concurrently, the first comment and the second comment on the touch screen display.
摘要:
An apparatus for forming a surface reservoir to hold a sample for a desirable period of time is described. The apparatus contains a platform, a solid surface disposed onto the platform, and an assembly of a bottomless vessel mounted on the solid surface. Also described is an apparatus that forms an array of surface reservoirs on a solid surface when multiple bottomless vessels are used, which can be used for high throughput applications. The apparatus can be used in applications on a solid surface, such as immunohistochemistry (IHC), oligo synthesis, peptide synthesis, ELISA, DNA array, peptide array, protein array, antibody array, tissue array, cell culturing, etc.
摘要:
A VCM power protection circuit that limits the maximum voltage that can occur across any of the VCM's output FETs, while at the same time providing some bias on a VCM output to direct a head toward a landing zone during power-up or any time there is a higher than normal voltage on the power supply.
摘要:
A system and method for monitoring and managing a computing service are disclosed. In one embodiment, an agent is installed at each of a plurality of clients. These agents periodically test performance of services of one or more application servers over a network. The agents then transmit the results of the tests to a management server. The management server also receives information regarding actual services delivered to users from the one or more application servers. Customers may then access the management server to obtain system information.
摘要:
A method and system for synchronization indicator enabled online meetings are disclosed. According to one embodiment, a computer implemented method comprises transmitting a screen change signal from a presenter system, the screen change signal indicating a change in presentation material. One or more synchronization signals are received at the presenter system, the one or more synchronization signals indicating current viewing status of one or more participant systems. The current viewing status of the one or more participant systems is updated based on the one or more synchronization signals.
