Abstract: Visual and audio communication interface for a perishable integrity indicator system which includes a RFID transponder and perishable integrity sensor. A perishable integrity indicator system includes a RFID transponder and a perishable integrity sensor. The RFID transponder includes a RF integrated circuit coupled with an antenna. The sensor monitors the time and temperature of the perishable. A freshness determining module receives time- and temperature-dependent measurement data from the perishable integrity sensor and determines a current freshness status. A communications interface to the RFID transponder permits a RFID reader to retrieve current freshness status data corresponding to the freshness status determined by the freshness determining module. The system further includes a power management module.

Abstract: A computer system includes a display screen, and is capable of displaying in a portion of the display screen (i.e., a "window") a portion of display data generated for display on the entire display screen. The computer system includes a first memory structure for storing data generated for display on the entire display screen, the fist memory structure receiving data in a manner independent of the size and location of the window on the display screen. A second memory structure contains data corresponding to the data stored in at least a selected portion of the first memory structure at a first point in time, where the portion corresponds to the display data displayed in the window.

Abstract: A method for displaying information within windows which are capable of overlapping on a video display of a computer controlled video display system, wherein said windows are defined by an operating environment on the video display independently of the writing of said video display data comprising the steps of:providing a memory means within said computer including at least one pseudo-screen buffer memory means for storage of display data;writing display data to said at least one pseudo-screen buffer memory means without calling said operating environment;storing current display data in said pseudo-screen buffer memory means;determining the visible display area of said windows on said video display for video display data associated with said windows; anddisplaying said video display data associated with said windows from said pseudo screen buffer memory means on said visible display area of said windows.
