Cellular mobile phone with a plurality of accessing telephone numbers for allowing access to the mobile phone by any one of the telephone numbers

Mobile Phone Patent Abstract An adapter for a cellular mobile phone unit which converts the unit to include a plurality of telephone numbers. A main circuit board is coupled to a microprocessor of the unit, which board includes a plurality of number assignment modules, or NAM’s (ROM’s), each NAM having its own unique telephone number code. The NAM’s are connected such that fifteen of the sixteen pin-connections of each NAM are correspondingly and respectively connected in series, for coupling to the fifteen pin-connections of a plug at one end of a ribbon cable, the other end of the ribbon cable being coupled to the microprocessor of the unit via the conventional NAM connection therefor. Each remaining pin of each NAM, which is not connected in series, is connected to a unique … Read entire article »

Mobile phone antenna with improved impedance-matching circuit

Mobile Phone Patent Abstract A new antenna structure for a mobile phone mainly comprises an antenna stem, a swivel joint, a high-frequency connector, and an impedance-matching member; the swivel joint includes an antenna-mounting base, a joint-fastening base and an outer protection sleeve; the swivel joint has a very small height in the whole antenna structure; the swivel joint enables the extension antenna stem to turn freely, and to bend for storage and carrying, if necessary. The copper and spring-shaped impedance-matching member and a copper sleeve wall of the high-frequency connector form into an impedance-matching circuit; the impedance-matching member is made of a standard parts without test and adjustment so as to facilitate the assembling operation thereof, … Read entire article »

Method for the control of receiver synchronization in a mobile phone

Mobile Phone Patent Abstract A receiver synchronization control in signalling messages in TACS/AMPS system in a mobile phone is disclosed. In order to avoid unnecessary setting of hunt mode operation, if the received synchronization pattern is not congruent with the correct reference pattern, the received pattern is checked in a bit-by-bit manner so as to reveal occasional bit errors of one or two bits, which may appear although the receiver is in synchronization. A further check may be conducted by shifting a reference pattern mask by one or at the most two bits in either direction, whereafter rechecking to reveal either fully correct pattern or rechecking for only one or two bits error can be performed. … Read entire article »

Transmitter switch-on in a dual-mode mobile phone

Mobile Phone Patent Abstract A method for providing a positive transmitter power switch-on in a dual-mode mobile phone is disclosed. According to the invention the transmitter is switched on in two or more phases, controlled by the mobile phone microprocessor program. Preferably the power amplifier sections are switched on in a sequence, so that the output power amplifier sections (3 and 4) are first switched on by enabling the transmit enable signal (TXE). Then the input power amplifier sections (1 and 2) are switched on by enabling ramp-up signal (RAMP-UP) Transmission is thereafter enabled by the transmit power control signal (TXC) being switched on, the amplifiers then output the amplified radio frequency input signal (RFIN) to … Read entire article »

Indication of data blocks in a frame received by a mobile phone

Mobile Phone Patent Abstract FIELD OF THE INVENTION The present invention relates generally to communication systems and, more specifically, to a mobile telephone capable of both speech and data communication in a digital mobile telephone system. BACKGROUND OF THE INVENTION Mobile telephone use has evolved into a critical communication link for information flow. Originally, mobile telephones were capable of transmitting and receiving only speech signals. The proliferation of data transmission, such as facsimile and computer information, made it necessary for mobile telephones to be capable of both speech and data communication. This additional capability has been achieved primarily through the use of digital telephone network that are capable of converting analog speech signals to digital signals … Read entire article »
