Abstract: A countdown timer application (computer program) that runs on programmable personal digital devices (“devices”) such as smartphones, tablet computers, and mobile Internet devices. The application is able to run several timers at once with different end times, the same end time and different beginning times, and one timer after another such that the end of one countdown triggers the beginning of another. Timers can repeat, such that when timer reaches zero it alerts user and begins to count down again indefinitely. A plurality of methods of alerting the user that the timer has reached zero are speaking a recording; displaying a photo or a video, playing music, and displaying text. Further, timers can be triggered based on awareness of the device's various sensors' states. Further, a version of the application uses synchronized devices, wherein the acknowledgment or non-acknowledgment of an alert on one device triggers notification on another device.

Abstract: A central site may provide downloading and processing services for a plurality of satellite sites that may perform capsule endoscope procedures. Processing may include reviewing image data acquired by a capsule endoscope and performing an at least partial analysis or review of the data reviewed.

Abstract: In a shutter-priority automatic single lens reflex camera the operator views the scene through an eyepiece viewfinder whose optical path is through a variable iris diaphragm and a taking lens. When a depth of field preview button is pushed by the operator, the diaphragm closes down to the aperture (opening) determined to be correct for the selected speed under the ambient light conditions. A system is provided to aid the operator in envisioning a black-and-white picture of a color scene by presenting a partially color deleted view of the scene to the eyepiece viewfinder. The operator pushes a button which pulls a special color filter into the optical path of the viewfinder and simultaneously sends a control signal to the camera central processing unit (CPU). The CPU, upon receiving the control signal, determines the proper diaphragm opening for the scene, compensates for the filter (by stopping up) and permits operation of the diaphragm to close down to the compensated aperture.
