Abstract: A television schedule system and method for displaying television schedule information on a television screen includes a program guide having a schedule information area that depicts the programs that are being presented on each channel at each time during the day. An input device allows the viewer to move a pointer over different interactive areas of the guide and the function performed when the area is activated is displayed in a contextual help window. Various control glyphs provide for recursive interaction with the guide. Additionally, a video window is interactive and provides tuning functions.

Abstract: A dual smart battery mutual detection system that utilizes intelligence built in to "smart batteries" in combination with a battery presence pin for enabling each battery of a dual battery power supply system of a PC to detect the presence, or, more importantly, the absence, of the other battery and to react accordingly is disclosed. In one embodiment, upon detection by the battery that is not being used to power the PC (the "inactive battery") of the removal of the battery that is being used to power the PC (the "active battery"), a microprocessor internal to the inactive battery closes an internal switch thereof, thereby causing the previously inactive battery to be "selected" and used to power the PC.
