Abstract: A system controller (102) operates in a messaging system (100) to deliver a response to a message. The response is communicated to a messaging terminal (115) at a response telephone number. The messaging terminal (115) includes a voice receive mode or a data receive mode, or both. A message input handler (404) receives the message and the response telephone number during a telephone call. A memory (408) stores the response telephone number in correspondence with the message. The message input handler (404) also receives the response, associates the message stored in the message memory with the response, and retrieves the response telephone number corresponding with the message associated with the response. A telephone response handler (420) delivers the response in accordance with the receive mode of the messaging terminal (115), using the retrieved response telephone number.

Abstract: A selective call radio frequency (RF) communication device (105) includes a receiver (203) for receiving and converting an RF signal into a converted signal. A controller (206) generates binary message information, a synchronization command signal and an address detection signal. An alert device (207) indicates the receipt of the message information. A frequency counter (427) measures the frequency of the converted signal and also determines the associated binary state of the binary message information. A measurement memory (439) stores the converted signal frequency measurements. The frequency control generator (440) generates a frequency control signal in response to the synchronization command signal being generated. The frequency control signal is a function of the stored converted signal frequency measurements and the associated binary states.

Abstract: A stacked double balanced mixer (220) includes a double balanced mixer (320) and a first cross coupled differential mixer (330). The double balanced mixer (320) includes two input transistors (321, 322) and four cross coupled output transistors (323-326). The first cross coupled differential mixer (330) includes four cross coupled input/output transistors (331-334) and a second mixer output (227, 228). The four cross coupled input/output transistors (331-334) have first output terminal pairs DC coupled in series to second output terminal pairs of the four cross coupled output transistors (323-326). The stacked double balanced mixer (220) generates, at the second mixer output (227,228), a second IF differential output signal having a second IF frequency at a difference of a radio frequency of a differential input signal and the sum of first and second LO frequencies, respectively, of first and second LO signals.

Abstract: A portable vibratory alerting device (20) is part of a resonant system (20, 30) and has a resonant vibrator (60) for both generating a vibrational alert and sensing the resonant frequency of the resonant system. The vibrator (60) is driven by a variable frequency driver (76, 78), and thereafter the resonant frequency is measured by a sensor (82). A vibration controller (72) causes the frequency of the vibrator to be substantially equal to the resonant frequency of the system.Alternately, a portable alerting device (520) has both a vibrator (160) and a sensor (166) for sensing the amplitude of a vibratory alert at various frequencies. A vibration controller (72) generates a vibratory alert at an optimum frequency in response to the sensed amplitudes.

Abstract: A system controller (102) is for generating a compressed facsimile message in a radio communications system (100). The system controller (102) includes an image memory (203) for storing an optical image, means for image analysis (205), means for best scan angle identification (204), an image rotator (220), and a facsimile encoder (225).

The means for best scan angle identification (204) identifies a best scan angle from one or more image analyses generated by the image analysis means (205). The image rotator (220) generates an aligned optical image by using the stored optical image and the best scan angle. The facsimile encoder (225) generates the compressed facsimile message from the aligned optical image.

Abstract: A method and apparatus for reliably delivering information service messages (300) from a central terminal (106) to a communication receiver (118) in a wireless message communication system (100). The communication receiver (118) receives information service messages including an information group identifier and data updates corresponding thereto. The communication receiver (118) receives disable messages (400) including an expiration time. The communication receiver (118) decodes received data updates (306) when the information group identifier (226) is determined as enabled. It does not decode received data updates (306) when the information group identifier (220) is determined as disabled (222). The communication receiver (118) determines enabled status as a default condition, and determines disabled status when a disable message (400) was received.

Abstract: A method and apparatus for underencapsulating a component (502) on a substrate (402). The method robotically places an underencapsulant film (406) on at least one surface of a first surface of the component (502) and a second surface of a substrate (402), the first and second surfaces substantially opposing each other when the component (502) is placed on the substrate (402). Next, the method places the component (502) on the substrate (402) to dispose the underencapsulant film (406) between the first and second surfaces. The method then bonds (1006,1008 or 1006,1010) the component (502) to the substrate (402) with the underencapsulant (406).
