Abstract: Methods, devices and systems for providing accurate measurements of timing errors using optical techniques are described. An example timing measurement device includes an optical hybrid that receives two optical pulse trains and produces two or more phase shifted optical outputs. The timing measurement device further includes two or more optical filters that receive the outputs of the optical hybrid to produce multiple pulse signals with distinctive frequency bands. The device also includes one or more photodetectors and analog-to-digital converters to receive to produce electrical signals in the digital domain corresponding to the optical outputs of the hybrid. A timing error associated with the optical pulse trains can be determined using the electrical signals in digital domain based on a computed phase difference between a first frequency band signal and a second frequency band signal and a computed frequency difference between the first frequency band signal and the second frequency band.

Abstract: A wall mounting system is described having a wall mounting bracket to be rigidly secured to a wall, a pair of water bottle filling station-mounted brackets to be rigidly secured to a water bottle filling station, and a pair of bracket adaptors, each configured to be secured to a respective one of the water bottle filling station-mounted brackets and to the wall mounting bracket. The system can include one or more springs. The system allows an operator to properly install a water bottle filling station on uneven walls or damaged or improperly installed wall mounting brackets.

Abstract: A method and system comprises transmitting an identifying code to a server. The identifying code identifies at least one media file associated with a user. The media file comprises at least one image obtained at a venue. The user's order for purchasing contents of the media file is transmitted to the server. The contents are received from the server for viewing and editing. Destinations for receiving purchased contents are transmitted to the server. The destinations comprise at least a first and a second location accessible from internet connections. The server transmits the purchased contents to the first and second locations. The first location is configured to be operable for storing the purchased content for retrieval by the user. The second location is associated with a manufacturer of items in which a visual representation of purchased contents is affixed to one or more items.
