Abstract: Tuners with high input impedance are connected to a common radio frequency (RF) signal source. A termination load external to the tuners provides matched impedance loading for the transmission line or cable driving the tuners. Alternatively, the termination load can be located inside one tuner with a switch to enable or disable the load. All tuners receive the same signal and no signal degradation is caused when connecting multiple tuners. The multiple tuner connection is useful in television signal receiving devices that receive more than one independent channel, such as digital video recorders or picture-in-picture television receivers.

Abstract: A method and apparatus for delivering content wirelessly to a remote wireless device (103) includes withholding content delivery until a link ready acknowledgment has been received. A communication device (201), such as a mobile telephone, includes a client capable of delivering content. For example, an audio client (101) is configured to deliver audio content, which may include music or voice, to a user. When a wireless communication link (210) with a remote wireless device (103), such as a hand-free speakerphone device, is desired, the client requests the wireless communication link from an audio manager (102). The client then withholds content delivery until the audio manager (102) establishes the wireless communication link (210) and delivers a link ready acknowledgement. In so doing, the method and apparatus prevent lost audio.

Abstract: For carrier growth planning in a wireless network, one or more airlink data transfer performance indicators are measured for a plurality of wireless units at a number of different times. The performance indicators may include user perceived throughput (UPT) and transmission latency or delay, as relating to batch or burst data transfers. Typically, the performance indicators are measured as a function of airlink loading, such as percentage of busy slots. After one or more optional statistical procedures, such as averaging, the performance indicators are compared to one or more performance criterion. In the case of UPT, for example, the performance criteria may be a set or range of minimum desired UPT values, for different loading levels, as established by the service provider. If the performance indicators meet the criteria, this indicates against adding airlink bandwidth in an effort to improve performance. Otherwise, increased airlink bandwidth may be warranted.

Abstract: A method for enabling a mobile phone to control the automatic activation/deactivation of the call waiting feature in real time through the use of customized pre-set user preferences. The mobile phone contains a database with multiple records for people and/or businesses known to the user. Within each record, the user may define a priority number. Each priority number is a scaled integer value, with low priority numbers representing a high priority record and high priority numbers representing low priority records. If the mobile phone detects an incoming call while a call is already in progress, a call waiting utility notifies the user of the incoming call if the incoming call corresponds to a preset priority number that is less than or equal to the priority number of the current call. Otherwise, the incoming call is directed to the user's voicemail system without interrupting the current call.

Abstract: Security is provided in a wireless communication system in a moving vehicle, e.g. an aircraft, by requiring user input of one or more security codes for validation before the system permits communication. One code, a security access code (SAC), corresponds to the vehicle travel segment (e.g. flight) and is given to the passenger(s) in transit, e.g. after the aircraft reaches a particular altitude. The second type of possible code, a personal identification number (PIN), is given to the passenger after baggage check-in. The PIN code would be correlated to the passenger and/or seat assignment. The use of either or both codes helps prohibit connectivity for mobile phone handsets or other wireless devices stored in the cargo bay or in other baggage. PIN use enables associated data systems to report the seat number or location of all parties engaging in wireless communications within the vehicle.
