Apparatus, and an associated method, for companding communication data. Companding is provided for a two-way radio communication station operable pursuant to a coded squelch scheme, such as an MURS or FRS radio. A baseband processor invokes compression operations upon originating communication data that is originated at the communication station. And, the processor invokes operation of expansion operations when the communication data comprises terminating data.

Connector apparatus, and an associated method, by which to apply electrical power to a set of consumer electronic devices, such as a laptop computer and a mobile phone, or other portable device. The connector includes an input port to which a source of input power is applied, such as the electrical power provided by way of a power cable of the laptop computer, once suitably connected to a source of permanent electric power. The connector apparatus includes a set of output ports, a first port of which is connectable to the laptop computer and a second port of which is connectable to the other portable electronic device. A user of the consumer electronic devices is able thereby to power both of the devices with connection of only a single power cable to a permanent power supply source.

A method and system is disclosed for transmitting two related channels of signals through the air. A first channel of signals is modulated with a first carrier frequency, and a second channel of signals is modulated with a second carrier frequency. The modulated first channel of signals and the second channel of signals are then combined through a high isolation combiner. Thereafter, the combined signals are transmitted toward a receiver system. After receiving the transmitted signals, the first channel and the second channel of signals are regenerated in the receiver system by separating one from the other.

Apparatus, and an associated method, for facilitating personalization of a weather band radio that receives SAME messages broadcast by the NWR system. Alphanumeric indicators of locations are displayed upon a user display element. And, a listener of the radio enters, by way of a user input actuator, selection of selected geographical areas, identified by the alphanumeric indicators. The selected alphanumeric location is used to form a six-digit location code defined by the Federal Information Processing Standards (FIPS). And, the code so-formed is used by the weather band radio, selectably to alert weather anomalies broadcast by the NWR system within the selected geographical area of interest.

Provided is a transmitter that includes a channel selector for modifying an operating frequency of a radio-controlled toy. The transmitter has a channel selection switch that enables a user to pick a channel from a set of predefined channels. The selected channel is then transferred to the toy. For example, a microcontroller unit within the transmitter may be used to detect the selected channel. The toy is placed in contact with the transmitter and the transmitter's microcontroller unit communicates the channel to a microcontroller unit inside the toy. The toy's microcontroller stores the channel in a memory in the toy. The toy then tunes to the stored frequency to receive control signals from the transmitter.
