Abstract: A mobile station and a method of conserving battery power consumed thereby. In one embodiment, the mobile station includes: (1) a chassis having a display and (2) a proximity sensor coupled to the chassis and adapted to cause a power consumption of the display to be reduced when the display is within a predetermined range of an external object.

Abstract: A charge meter system and method of compiling utilization fees associated with a data transmission in a packet switched communications network. In one embodiment, the charge meter system includes a counter that counts a number of data packets associated with the data transmission and a charge rate subsystem that obtains a charge rate associated with the data transmission. The charge meter system also includes a calculation subsystem that calculates utilization fees based on the number of data packets and the charge rate of the data transmission. The charge meter system further includes an indication subsystem that provides the utilization fees to a user via user equipment participating in the data transmission.

Abstract: A system for, and method of, selecting one of at least two different candidate wireless communication networks for data communication by a mobile communication device and a wireless communication device incorporating the system or the method. In one embodiment, the system includes a network selector that employs the mobile communication device to perform data transfers between the mobile communication device and communication server associated with the at least two different candidate wireless communication networks and performs an evaluation of the at least two different candidate wireless communication networks based on at least one data communication quality parameter.

Abstract: A mobile telephone, a method of employing a mobile telephone to measure a vital sign and a vital sign measuring system. In one embodiment, the mobile telephone includes: (1) a vital sign measuring system, (2) a keypad, coupled to the vital sign measuring system, configured to allow a user to control the vital sign measuring system and (3) a display, coupled to the vital sign measuring system, configured to provide vital sign information to the user. In other embodiments, a microphone on the mobile phone allows the user to control the vital sign measuring system by voice command, and a loudspeaker on the mobile phone provides the vital sign information to the user.

Abstract: A system for, and method of, using a mobile telephone to retrieve information about an article and an associated mobile telephone. In one embodiment, the system includes: (1) a camera, associated with the mobile telephone, that records an image of coded data associated with the article and (2) a database, remote from the mobile telephone, that supplies information about the article to the mobile telephone based on a received, decoded form of the coded data derived from the image.
