Abstract: Apparatus embodiments of the invention are disclosed for requesting power via a wired interface. In example embodiments, a pull-down circuit in the apparatus acting as a power consumer when there is no energy in the apparatus, is connected via a configuration line over a cable to a power provider device. The apparatus may be in a power down mode, it may have an empty battery, or it may have no battery. The pull-down circuit is configured to use energy from the configuration line to pull down a voltage on the configuration line, to signal the power provider device to provide power over another line of the cable to the apparatus.

Abstract: An apparatus with a memory that has a learning database and a user database. The learning database has a set of details to be learned and the user database has a user profile. The user profile has a weighing vector of weighing parameters corresponding to the set of details. The apparatus further has a processor configured to test a user for particular details in an order that is at least partly based on the weighing parameters. The processor is further configured to adjust the weighing parameter corresponding to a given detail depending on whether the user has passed the test. Also corresponding methods and computer programs are disclosed.

Abstract: A method, an apparatus, and a computer program product embodiments are disclosed for detection of the availability of a battery (160) by a host terminal (100) during a data exchange session with the battery (160). In accordance with the embodiments of the invention, sampling, data communication with the battery pack (150), and detection of battery (160) removal, may occur substantially simultaneously. The battery (160) removal may be detected during data transmission from the terminal (100) to the battery pack (150). Moreover, a response may be received by the terminal (100) from the battery circuits (155) in response to data communicated to the battery (160) on the battery communication line (140), during sampling in a timed manner.

Abstract: A method for training involves maintaining a plurality of details to be tested; maintaining group definitions which define a plurality of groups associated with two or more of the details; determining a test detail; outputting to a user a question to which the test detail is a correct answer; inputting from the user an answer to the question; determining whether the answer comprises more than one parts. If yes: determining other details belonging to a common group with the test detail; determining which if any of the test detail and of the other details match the parts of the answer and considering such details as correctly answered details; and storing for each correctly answered detail an indication of a correct answer. If the answer comprises no more than one part, then: determining if the answer correctly matches the test detail; and if yes, storing an indication of a correct answer.

Abstract: A charging plug for charging a mobile terminal, includes a plug element for carrying current, and also includes a portion extending beyond the plug element. That portion is long enough to prevent the plug element from contacting the mobile terminal, if the mobile terminal requires a smaller current. However, the portion is short enough to allow the plug element to contact the mobile terminal if the mobile terminal is equipped to handle the current carried by the plug element. According to an additional embodiment, the portion extending beyond the plug element will provide the smaller current if the smaller current is required.
