A system and method is provided for monitoring a plurality of audio sources and switching from one to another of the audio sources in accordance with a stored program. An audio output device receives a signal from each of the portable electronic devices and selectively switches the contents of its output according to at least one preprogrammed user preference. The audio output device also automatically communicates with transceiver modules connected to local information systems, for example within a vehicle, office or shopping center. Based on programs stored in a storage device connected to the headset, the local information sources may be monitored and selected to interrupt other audio sources received by the headset when desired.

Proximity regulation systems for use with a portable cell phone, a portable cell phone and a method of operating the same. In one embodiment, the proximity regulation system includes a location sensing subsystem configured to determine a location of a portable cell phone proximate a user by determining a mode of operation of the portable cell phone. A power governing subsystem is coupled to the location sensing subsystem and configured to determine a proximity transmit power level of the portable cell phone based on the location.

In accordance with the principles of the present invention utilizing the BLUETOOTH specification Cordless Telephony profile, incoming calls to a cell phone including a Gateway role can be routed to another piconet device (e.g., another cell phone including a Terminal role. Two cell phones with BLUETOOTH capability each include the Cordless Telephony Profile. The cell phone receiving the call acts as a PSTN cordless telephone Gateway cell phone via the cellular network, while the other cell phone acts as a cordless telephone Terminal cell phone. The cordless telephone Terminal cell phone then acts as an extension to the Gateway cell phone allowing both calls to the Gateway cell phone to be answered at the Terminal cell phone, and even allowing calls by the Gateway cell phone to be originated by the Terminal cell phone. Moreover, the present invention includes the ability for any one of a number of authorized Terminal devices (e.g., Terminal cell phone) to answer an incoming call to a Gateway cell phone ‘on the fly’ after hearing the ringing at the Gateway cell phone.
摘要:
A method and system for providing an accurate service record to communication devices seeking modem-based services. The system includes a phone line detector capable of detecting whether a properly working phone line connection exists. This can be accomplished by detecting whether a phone line is actually plugged into a phone jack connected to a modem of a communication device. If a proper phone line connection exists, then the communication device generates a service record identifying, among other services, all modem-based services that the communication device can offer to other communication devices in search of a modem or modem-based service.

A wireless piconet network device includes a GPS receiver to determine and provide earth coordinates to a gatekeeper of a wireless network so as to provide a level of security to wireless networks which requires accessing wireless devices to be within predefined boundary coordinates. The automatic restriction of access to a wireless network (e.g., a wireless local area network (LAN) such as a piconet network) by requiring a wireless network device to provide earth coordinates (e.g., GPS location information) as part of an establishment or maintenance of a connection to a wireless network, independent of a range of communication of any device in the wireless network. A wireless piconet network device outside of predetermined earth coordinates of a secured area (e.g., a building, a room in a building, a desk in a room in a building, etc.) may be denied access to resources on the wireless network, and/or required to provide additional authorization information so as to confirm authorized secured status of the entering wireless device.

An application usage time limiter monitors certain pre-configured application programs when opened or otherwise executed on a computer (e.g. a PC). The application usage time limiter is itself a program running either as a front end to various selected programs for monitoring, or as a separate program running in a time-sharing operating system environment. Pre-configurable options in a usage limiter configuration file or other memory area are set to limit real time ranges that particular application programs on a particular computer can be started and run, and a limit to a length of time that a specific program (or category of programs-an be operated given a number of available credits for a current user. The user is given credits at a pre-configured rate per hour of usage of an application program designated in the usage limiter configuration file as being beneficial, and the user gives back (or looses) credits at a pre-configured rate per hour of usage for use of programs designated as non-beneficial. Preferably, continued usage of beneficial programs is detected, e.g., by keystrokes. Application programs selected for monitoring in the usage limiter configuration file can be identified on an application by application basis, as a specific category of applications identifiable when the particular application is started, or as being stored in a specific directory (e.g., folder in a Windows™ operating system). A credit-giving (i.e., beneficial program) must be run by a particular user to earn credits before a credit-taking (i.e., non-beneficial program) can be run by that user. Up front credits may be provided to a particular user in a user log.
摘要:
When a plurality of cordless telephones (e.g., digital cordless telephones) are used within range of one another, base units of one or more of the digital cordless telephones may receive transmissions from others of the digital cordless telephones. Conventionally, the base unit would simply ignore information relating to that received from an unintended remote handset, i.e., a remote handset having a security code which fails to match that of the receiving base unit. However, in accordance with the principles of the present invention, information regarding the unique security code received with respect to other remote handsets (i.e., those having security codes which do not match that of the receiving base unit), are logged and used in a way which provides a unique best available channel list to each of the digital cordless telephones so that similar digital cordless telephones operating in a similar environment do not attempt selection of channels in a similar way (causing channel inclarity and/or interference). In a first embodiment, the list of best available channels is randomized based on the unique security code of the relevant digital cordless telephone. In a second embodiment, the list of best available channels is randomized only when another digital cordless telephone becomes within transmission range of the relevant digital cordless telephone. In a third embodiment, a list of best available channels is uniquely indexed for each digital cordless telephone based on a ranking of the digital cordless telephones within transmission range of one another. For instance, the highest ranking digital telephone in an environment with three digital cordless telephones attempts use of, preferably in order, the 1st, 4th, 7th, 10th, etc. channels.
摘要:
The current draw of a wireless device, e.g., a cordless telephone, is minimized for a cradled remote handset drawing power from an AC outlet. This allows a greater portion of the total current amperage provided by the AC to DC converter to be allowed to charge the battery in the remote unit, and reduces the overall maximum or peak value of the current draw of the wireless device. With an improved peak power budget, a smaller (and presumably less expensive) AC to DC adapter than otherwise necessary may be used to power the wireless device. In one aspect, sniff operations of the remote handset are disabled or otherwise suppressed while the remote handset is in the cradle of the base unit, e.g., receiving a quick charge or trickle charge to its battery. In a second aspect, sniff operations of the base unit are disabled or otherwise suppressed while the remote handset is in the cradle of the base unit. In a last aspect, the charging mode of the battery in the remote handset of a wireless device changes based on activity in the remote handset.
