The application serves the first request by accessing a first data set organized using a first application schema. The application serves the second request by accessing a second data set using a second application schema.

Abstract: Disclosed herein are techniques for adjusting the interpupillary distance (IPD) of an optical device. A system for IPD adjustment includes a first nonmoving component, a sliding assembly comprising a button, and a pair of magnets, wherein a first magnet of the pair of magnets is coupled to the sliding assembly. The pair of magnets is configured to exert a magnetic force on the sliding assembly in a first direction to press the sliding assembly against the first nonmoving component to lock the sliding assembly to the first nonmoving component. The sliding assembly is configured to, when the button of the sliding assembly is pushed by a force in a second direction opposite the first direction of the magnetic force, disengage with the first nonmoving component and become slidable with respect to the first nonmoving component.

These abstraction layers and associated functionality free users not only from having to implement and configure provider-specific protocols, but also from having to address interdependencies among selected hardware, software and license servers on a job-level basis or at other levels of granularity.

Abstract: In one embodiment, enhanced packet flow monitoring is performed by packet switching devices in a network. A packet switching device is configured to monitor a flow of packets passing through the packet switching device, including detecting a gap in consecutive packets of the flow of packets, and attributing the gap as not being dropped one or more packets based on a particular time duration between a last received packet of the flow of packets before said detected gap and a first received packet of the flow of packets after said detected gap. In one embodiment, the gap is attributed to not being dropped packets when the particular time duration is greater than a threshold value; and conversely, attributed to being dropped packets when the particular time duration is less than a same or different threshold value.
