An optical assembly can be used in various optical devices such as optical proximity sensors, gesture sensors, or imaging sensors. The connector assembly employs a first connector with cam follower projections, a base housing with guide channels, a slide cam housing including cam grooves and projection guide tracks, and a cover housing pivotally mounted on the base housing, the cover housing having a cover housing projection. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. Swap logic from the command queue may advantageously exchange a delayed command corresponding to a busy peripheral device, and substitute a non-delayed command for a non-busy peripheral device into the first location of the FIFO memory device to thereby permit the non-delayed command to be executed in a more expeditious and efficient manner. The obtained FCTSTFC data are then posted on the WWW server so as to allow the customer to gain access to these FCTSTFC data via Internet.
