Mobile Phone Patent Abstract A mobile phone in-call indicator for connecting to an antenna of a mobile phone is provided. The in-call indicator mainly includes a lower base having a lower bolt part and an externally threaded head, an upper base screwed to the threaded head of the lower base and having a light-emitting diode and a circuit board mounted thereto, and an ornamental cover rotatably fitted around the upper base to cover the upper base. In case the in-call indicator is mounted onto the mobile phone with the ornamental cover facing toward a direction not exactly the same as that of the mobile phone and therefore resulting in an inconsistent appearance, the cover may be adjusted in its direction simply by separating the upper base from the lower base and … Read entire article »

Mobile Phone Patent Abstract A motor vehicle built-in unit for a mobile phone has a central control unit and an interface for exchanging signals between the central control unit of the mobile phone and the motor vehicle. The built-in unit also has a motor vehicle-specific adapter control unit for adapting functions of the interface and/or of the central control unit to the respective type of motor vehicle. The modular design allows for electrical and mechanical adaptation to various types of motor vehicles so that the central control unit and interface can be identical for a wide variety of motor vehicles. An alternative built-in unit has a central unit and an interface for connecting to the motor vehicle. The interface is designed to connect the built-in unit to the motor vehicle selectively … Read entire article »

Mobile Phone Patent Abstract A circuit for at least substantially eliminating at least one external interference signal from a radio communications signal received by a code division multiple access (CDMA) mobile phone including a receiving terminal and a low noise amplifier comprises: a plurality of damping devices operatively coupled between the receiving terminal and the low noise amplifier; a plurality of switches respectively operatively coupled between the plurality of damping devices and the receiving terminal; an interference detector operatively coupled to the receiving terminal for detecting the at least one external interference signal from the received radio communications signal; and a switch driver operatively coupled between the plurality of switches and the interference detector, the switch driver generating a switching signal in response to the interference detector to select at least … Read entire article »

Mobile Phone Patent Abstract A mobile phone handset having a housing that includes a front part and a back part, in which the front part and back part housings are joined in an overlapping manner. The mobile phone handset is capable of allowing significant variations on the physical appearance of the handset such as changing the shape of the front face. These variations involve no re-design of the back part and a core of the phone because the housing of the front part overlaps the housing of the back part when being connected. … Read entire article »

Mobile Phone Patent Abstract A mobile phone battery charger with a power cord winding mechanism is disclosed. The battery charger is formed with a power cord receiving chamber in which a winding reel is disposed. An upper end surface of the winding reel is disposed with two contacts connected with the power cord. One contact is disposed at the center of the upper end surface of the winding reel, while the other contact is formed as a circumferential contact around the central contact. A pair of inner terminals of the power cord are respectively soldered at the two contacts, and a pair of outer terminals of the power cord are extended through a passage out of the battery charger. Two resilient plates extend from a diaphragm of the battery charger into … Read entire article »

Mobile Phone Patent Abstract A mobile phone with a display is disclosed, which automatically compensates for situations in which poor lighting conditions are likely, by producing a much larger, bolder font than normal. For example, the larger, bolder font is displayed when external power is applied to the mobile phone, or when the mobile phone is being operated in the hands-free mode. … Read entire article »

Mobile Phone Patent Abstract The balanced, retractable dipole antenna comprises a first radiator element that is selectively extendable from, and retractable into, a mobile phone casing, a second radiator element, and a counterpoise that is electrically isolated from a printed wire board (PWB) of a mobile phone . The balanced, retractable dipole antenna further comprises a signal balancing means coupled between a signal source and at least the second radiator element and counterpoise to generate first and second signals, respectively. The first and second signals are substantially equal in magnitude but out of phase by 180 degrees. When the first radiator is extended, the first signal is transferred to the first and second radiator elements, and the second signal is transferred to the counterpoise. When the first radiator element is retracted, … Read entire article »

Mobile Phone Patent Abstract The mobile phone is equipped for at least two frequency bands and includes an antenna coupled to a multiplex type filter. The multiplex type filter contains at least two disparate bandpass filters for separate reception or transmission frequency bands. A first bandpass filter of the at least two disparate bandpass filters has as a passband a first frequency band. A second bandpass filter of the at least two disparate bandpass filters has as a passband a second frequency band. An input impedance of the first bandpass filter in the second frequency band is higher than an input impedance of the second bandpass filter in the second frequency band, and an input impedance of the second bandpass filter in the first frequency band is higher that an input … Read entire article »

Mobile Phone Patent Abstract An apparatus and method for performing improved speech recognition in a communication terminal, e.g., a mobile phone with a hands-free voice dialing function. In a speech recognition mode, a user’s input speech such as a desired called party name, number or a phone command, is converted to feature data and compared to individual pre-stored feature data sets corresponding to pre-recorded speech obtained during a registration process. Difference values representing the respective differences between the current user’s input speech and the respective data sets are computed. A first closest (most similar) and second closest feature data set correspond to the first smallest and second smallest difference values so obtained. A closeness threshold is computed as the sum of a small, predetermined threshold and a differential value between the … Read entire article »

Mobile Phone Patent Abstract A hidden antenna device of a mobile phone, the mobile phone is comprised of an upper cover and a lower cover, a main electric circuit board is provided in the interior space formed by the two members. The lower cover has an antenna circuit printed at a suitable position on the inner bottom surface of the lower cover; the antenna circuit has a protruding end connecting point. A main electric circuit board in the body of the phone has on the rear surface thereof another connecting point in opposition to the aforesaid end connecting point. A ceramic layer and a matching electric circuit board layer having a desired frequency are provided between the antenna circuit and the main electric circuit board, so that when the upper cover … Read entire article »
