Abstract: A system may include multiple remote kiosk devices each to present a respective kiosk user interface and multiple remote receptionist devices each to present a respective receptionist user interface. The system may perform operations comprising receiving at the receptionist devices live video feeds captured by the multiple kiosk devices and providing the multiple live video feeds to the remote receptionist devices. The remote receptionist devices present the multiple live video feeds in the receptionist user interfaces The system may receive, from a receptionist device, a request to initiate a video call with a remote kiosk device, may initiate a video call between the remote receptionist device and the remote kiosk device, and may cause the user interface of the remote receptionist device to present the video call and the live video feeds simultaneously.

Abstract: Methods and apparatus useful for non-intrusive advertising on a mobile wireless communications terminal are disclosed. A method may include storing, according to a timed schedule, a plurality of files containing data representative of a plurality of advertising images in a memory of the mobile wireless communications terminal; and selecting, upon occurrence of a predefined event, one of the plurality of files for display as wallpaper on a display screen of the mobile wireless communications terminal. A method may include waiting for an occurrence of a event; determining, upon the occurrence of the event, if a contraindicated condition is present in the mobile wireless communications terminal, and if the contraindicated condition is not present: performing a first set of actions, but if the contraindicated condition is present: waiting for another occurrence of the predefined event.

Abstract: Misalignment errors in a lithographic system resulting from the effect of environmental changes on the lens system itself are detected and corrected. A fiducial on the reticle adjacent to its working area is projected through the lens. A metrology plate carried by the lens holds reference mirrors and detectors. The reference mirrors receive the resultant image and reflect it to detectors in a reflected image plane. This provides feedback to the reticle alignment system as to the extent of misalignment, if any. Correction is made by moving the reticle until alignment is achieved and detected. This motion is achieved by using a reticle chuck with linear motors.

Abstract: Two lithographic substrate stages are used in a single lithographic system. While a substrate on one stage is being exposed, a second substrate is being loaded, unloaded, or aligned on a second stage. After exposure, the first stage is unloaded, reloaded, and the newly-loaded substrate is aligned, while the second substrate on the second stage is being exposed. The two stages are thus used alternately in different steps of the process. One of the steps is being performed on one stage while a different step is being performed on the other stage. The substrates on both stages are, therefore, being acted upon simultaneously. The two stages are carried on a single linear motor platen, and moved about the platen by use of linear motors. The two stages alternately both move in clockwise directions about the platen, or both move in counterclockwise directions. When both move in clockwise directions, the first stage is moving to the exposure position, and the second stage is moving to the unload/load/align station.
