A low-gloss biaxially oriented polymer film containing a vinyl aromatic polymer and substantially non-spherical rubber particles is useful for window film applications. The top phase is formed from fibers, such as hardwood, that provide a tighter or more dense fibrous phase than the vegetable fibers used in the base phase. In accordance with a particular embodiment of the present invention, the respective cumulative talk times of each of the plurality of participants is graphically presented to at least one of the plurality of participants. As a result, the phase difference between the reference clock signal and the feedback signal is reduced to a sensitivity limit of a phase comparator in the DLL circuit. The nodes recorded in the partner list are called the partners of the owner of the partner list. Control circuitry is adapted to receive a command from the translucent key switch when it is depressed, retrieve the control data from the storage module, and provide the control data to the transceiver switch for transmission as the data signal, and to cause the light source to illuminate when the acknowledgement signal has been received.
