Abstract:
A circuit board includes an insulation body having a first surface and a second surface facing away from the first surface. The circuit board comprises a hardened insulation material. Circuit patterns having first conductive surfaces, second conductive surfaces facing away from the first conductive surfaces, and side surfaces connecting the first and second conductive surfaces embedded in the insulation body. That is, the second conductive surfaces and the side surfaces are embedded in the insulation body through the first surface of the insulation body, and the first conductive surfaces are exposed out of the insulation body. Recognition patterns are formed on the second surface of the insulation body.
Abstract:
A method for manufacturing a semiconductor package includes the steps of forming first circuit patterns on an upper surface of a carrier substrate. Bumps are formed in recesses defined on the upper surface of the carrier substrate. An insulation layer is formed on the upper surface of the carrier substrate to cover the first circuit patterns. Second circuit patterns are formed on an upper surface of the insulation layer so as to be electrically connected with the first circuit patterns. The carrier substrate is then separated from the insulation layer.
Abstract:
The present invention relates to a method for controlling a transmission power of a dual standby mode mobile terminal. A method of controlling a transmission power of the invention includes performing a conversation standby service with a first communications network while performing a conversation service with a second communications network, and receiving a first power control level from a base station of the first communications network; comparing a second power control level that corresponds to a power code, which is set for a current output signal power, with the first power control level; and decreasing a current power code when the first power control level is greater than or equal to the second power control level.
Abstract:
A multiple mode multiple standby mobile terminal and self configuration method of the mobile terminal are provided for automatically configuring settings on multiple Subscriber Identity Module (SIM) cards. An identity module configuration method for a multiple mode multiple standby mobile terminal includes checking, when the mobile terminal powers on, reference identity information in the mobile terminal, determining whether identity information contained in an identity card attached to the mobile terminal is included in the reference identity information and establishing, when the identity information is included in the reference identity information, a connection to a communication network indicated by the identity information.
Abstract:
A method for inter-processor communication in a mobile terminal is disclosed. The method of inter-processor communication for a mobile terminal having a first processor, a second processor, and a shared memory includes determining, by the first processor, the size of data to be sent to the second processor, comparing the determined size of the data with the size of one of multiple buffer areas in the shared memory to be used for transmission, rearranging the shared memory according to the data size when the size of the data is greater than the size of the buffer area to be used, and sending the data to the second processor through the rearranged shared memory. It is possible to increase data transfer rates between processors when inter-processor communication is performed through a shared memory in a mobile terminal having multiple processors.
Abstract:
A dual standby mode mobile terminal having a single smart card slot and communication mode control method thereof is provided for enabling the mobile terminal to operate in dual standby mode with a single smart card. A dual standby mode mobile terminal includes a first control unit for controlling a first communication mode, a second control unit for controlling a second communication mode, a removable dual mode smart card containing first and second communication mode data, and a buffer for loading the first and second communication mode data. A communication mode control method for the dual standby mode mobile terminal includes loading the first and second communication mode data in the buffer from the dual mode smart card under the control of the first control unit, detecting an event requiring communication mode data provided by the dual mode smart card, determining whether the communication data are any of the first and second communication mode data loaded in the buffer, and executing the event using the communication mode data loaded in the buffer. The dual standby mode mobile terminal and communication mode control method thereof enables the mobile terminal to stand by in two different communication modes (e.g. GSM and CDMA modes) with a single smart card.
