Abstract: A method and apparatus are disclosed that enable: (i) applications that are external to a telecommunications terminal, rather than the user, to initiate the delivery of content to the terminal, and (ii) the terminal to determine, based on the state of the terminal, whether or not to provide the content to a user. The “state” of the terminal is determined by one or more of (i) user-driven states, (ii) data states, and (iii) call states. When the terminal's state is considered, as in accordance with the illustrative embodiment of the present invention, the readiness of the user and terminal to accept and process the content are accounted for, and as a result the content does not interfere.

Abstract: A method and apparatus are disclosed that enable a telecommunications terminal to securely receive unsolicited content from applications that are external to the terminal. In particular, the present invention enables the terminal to control the interaction with external applications by using a secure, two-task process. In the two-task process of the present invention, the execution of the second task is based on verifying the trustworthiness of address information that is provided in the first task. This is in contrast to a one-task process, in which an untrustworthy server that provides content might hide its own address by substituting a legitimate address.

Abstract: An apparatus and a method are disclosed for handling multiple display modes, such as column-first and row-first display modes. In particular, a telecommunications terminal receives a computer file (e.g., an HTML-encoded file, etc.) from a content server. The computer file comprises a data-ordering tag, in accordance with the illustrative embodiment of the present invention, along with one or more displayable data items. Based on the data-ordering tag, the terminal with its browser first maps the data items into an N-row by M-column array of display cells in accordance with the illustrative embodiment, wherein N and M are positive integers. The terminal then displays the mapped data items in the array of display cells. The telecommunications terminal further comprises a two-dimensional array of buttons. Each cell in the array of display cells is associated with one or more buttons in the array of buttons.

Abstract: A protocol controls communications between a master unit and a plurality (M) of slave units connected thereto. The master unit sends a downlink message over a first communication path to the M slave units, the downlink message including a number N of information bytes, where N.gtoreq.M, each byte except a last byte comprising a data portion followed by a first predetermined control bit and the last byte comprising a status portion followed by a second predetermined control bit. The master unit receives uplink messages over a second communication path from the M slave units, the uplink messages having the same format as downlink messages. A third communication path connects between the master unit and the M slave units enabling a first slave unit to signal other slave units of the first slave unit's desire to send information to the master unit.

Abstract: A self-oscillating switching regulator includes an inductor which is switched across the input or output depending, respectively, on whether a control voltage does not or does exceed a predetermined threshold. The control voltage is generated from a predetermined sum of the output voltage and a voltage dependent upon the inductor current when the inductor is connected across the input.
