摘要： A power management unit (40) for a portable electronic apparatus is disclosed. The apparatus is powered by at least a battery (42), and the power management unit is implemented as an integrated circuit. The power management unit (40) may comprise a general purpose analog-to-digital converter block (57) comprising a first switch for selecting one of at least two analog input signals, and an analog-to-digital converter which is arranged to convert said selected analog input signal into a digital signal; an analog event generator block (52), which is arranged to provide an indication for controlling an operating state of said power management unit when an analog input signal assumes a predetermined relation to a predetermined reference value; a timer block (54), which is operable for providing a timing signal independently of which one of a plurality of operating states the power management unit is operable in; and/or a battery charge control block (53), which is capable of controlling a battery charge current based on an estimated charge power. Also disclosed is an electronic pen comprising the power management unit.

摘要： An integrated local communication system comprising a plurality of locally-positioned communication devices, at least one of which locally-positioned communication devices is operably coupled to a local interface module. A local communication link is selectably effectuated between any two locally-positioned communication devices via at least one local interface module by transforming a non-local communication signal into a local communication signal and transceiving the local communication signal using a single preselected communication protocol that is common to all local communication links. An exemplary embodiment may include at least one mobile station associated with a Public Land Mobile Network, at least one radio-enhanced phone interfacing device associated with a Public Switching Telephone Network, at least one electronic data terminal selectably disposed in a distributed computing environment, and at least one wireless headset for hands-free operability. Devices within the integrated local communication system also being capable of communicating with other devices in the integrated local communication system.
