The present invention relates to a wiper coupler that releasably attaches the superstructure to a wiper arm attachment member. The voicemail server is programmed to store a message from a calling party when the multimode mobile device of the called party is inaccessible by way of the telephony system, construct a voicemail notification corresponding to the recorded message, and transmit a wireless message including the voicemail notification directed to a select multimode mobile device. It is further characterized by one or more second logic elements that generate, for at least a selected user, a refined spread-spectrum waveform as a function of a sum of the residual composite spread-spectrum waveform and the estimated spreads-spectrum waveform for that user. A contact portion of each upper contact is located on a front side of the housing, for contact with an upper surface of a circuit card inserted into a receiving space of the housing. Also included in the invention are cells transformed with a polynucleotide according to the invention suitable for producing these proteins and cells.
