Abstract: The present subject matter includes a capacitor stack having a plurality of anode layers, and a plurality of cathodic metal substrates partially coated in a titanium coating. Cathode portions lacking titanium enable weld interconnections which are substantially free of titanium, improving capacitor properties. In some embodiments, anodes are interspersed among cathodes, and are electrically separated from the cathodes, with portions of cathode material attached to the welding area of the anode. These portions of the cathode material are no longer electrically connected to the cathode. As the anode and these cathode portions are welded and aged, leakage current is reduced due to improved oxide growth in the welding area due to the absence of titanium.

Abstract: The invention provides a method for a multimedia server to dynamically adjust the data rate that is streamed over an error-prone bandwidth-varying wireless network to a mobile multimedia client in a client-server architecture. The method enables multimedia applications to efficiently utilize the available (yet time-varying) wireless channel bandwidth and helps prevent interruption in the streaming due to client buffer underflow and packet loss due to network buffer overflow, hence significantly improving the multimedia streaming performance.

User input is accepted such as by manipulation of switches to control the telephone system so as to add predetermine prefix or suffix codes or data to one or more items of caller ID data in accordance with the occurrence or existence of predetermined conditions that must be signalled to the computer process using the caller ID data being formatted by the telephone system.

Abstract: A telephone system including improved voicemail wherein a digital signal processor scans data to be recorded in a voicemail message to find DTMF tones or DTMF mimics in the voice data and removes them from the recording. In one embodiment, the DSP scans for DTMF tones or mimics in the stream of data to be recorded and removes them before recording the data. In another embodiment, the DSP scans for DTMF tones and mimics in the stream of data to be recorded, and marks the starting point and ending point in the stream where DTMF tones or mimics are found, records all the data and then goes back to the recording after it is finished and looks for the markers and removes all data between the markers.

Abstract: A telephone system including improved automated routing of telephone calls based upon caller ID data. If caller ID data is received, it is used as a search key to search a routing table listing extensions normally called by one or more persons identified by their caller IDs. If a match is found, the call is automatically transferred to the extension or voice mail box listed in the routing table. In some embodiments, the caller is given options to block the automatic routing or block recording of a voice mail message in favor of transfer to a caller specified extension or to an attendant. Also disclosed is improved voice mail wherein a digital signal processor scans data to be recorded in a voice mail message to find DTMF tones or DTMF mimics in the voice data and removes them from the recording so that no false DTMF commands will be recognized during playback by any DTMF detector which is active during the playback.

Abstract: A telephone with a selectable level of sidetone for use in noisy environments. The selectable level of sidetone is achieved by forming a switch-controlled feedback path including a gain setting resistor from the output of a transmit amplifier in a hybrid circuit to a summing node virtual ground at one input of a differential amplifier driving the handset speaker. The summing node is also coupled to the audio output port of the three port hybrid so as to also receive incoming audio signals from the tip and ring lines. A microcontroller having configuration data controls whether the switch is closed and the feedback path exists or the switch is open and no feedback occurs. Lower sidetone or no sidetone is useful in phones used in noisy environments such as factory floors or restaurants.
