Abstract: A method of generating a video-based diary of a user's activities based on various information stored and/or collected by a mobile phone. More particularly, the invention provides a method of generating a video-based diary of a period of time based on information such as, for example, incoming, outgoing, and missed calls, voicemails, sent and received text messages, pictures, sound and/or video clips, location, emails, etc. The format and content included in the generated video-based diary can be predetermined by the user so that only desired stored information is included in the video-based summary. The generated video-based diary can be utilized by the user in the future as a reference for remembering past events. The generated video-based diary can also be uploaded via the phone to a blog, if so desired.

Abstract: Digital, serial communication over an interface between an electronic device (102) and a battery (103) attached thereto comprises transmission of bytes (300) consisting of a number of bits. Each bit is defined by one of a high level and a low level, and a leading bit (304) of each byte is of a first one of said high and low levels. The method comprises the step of transmitting the other of the high and low levels for a first period of time (403, 405) immediately prior to said leading bit (304). When the leading bit of a byte is always of the same level (i.e. either high or low) and a period of the opposite level precedes the leading bit, it is very easy and simple to ensure that the sending as well as the receiving party is ready for the communication to take place and adjusted to the actual direction of communication.

Abstract: A digital portable communications device (1) for communication via a communications network (28) has circuitry for exchanging video signals between the device and an external video apparatus (25; 31). The circuitry for exchanging video signals is arranged to exchange the video signals in the form of analog video signals. When analog video signals are used, the exchange of video signals with external video apparatuses is not limited to apparatuses adapted to a specific protocol for the exchange of digital video signals. Thus, it is not needed to have specific software drivers for different digital protocols in the communications device in order to communicate with a camera or a display unit. Any digital or analog camera, video recorder or video display unit can be used as an accessory to the communications device.

Abstract: A voltage/current regulator regulates charging of a rechargeable battery in a portable apparatus that includes a transistor and a controller means coupled to the transistor for controlling the charging current to the battery. The controller determines the power dissipation in the transistor of the regulator. If the power dissipation is above a maximum allowed power dissipation, the controller decreases the charging current by a particular current step. Otherwise, the controller determines if the power dissipation will exceed the maximum allowed power dissipation if the charging current is increased by the current step. If not, the controller increases the charging current by the current step.

Abstract: A method enables digital, serial communication over an interface between an electronic device (102) and a battery (103) attached thereto. The digital, serial communication comprises transmission of bytes (300) consisting of a number of bits. The method comprises the steps of transmitting a byte from a first one of said electronic device and said battery, receiving said byte in the other of said electronic device and said battery, and retransmitting said received byte unchanged. Hereby, it is possible to compare the contents of the returned byte with the contents of the byte originally transmitted, and thus ensure that the byte was transmitted correctly. This simple procedure makes other error handling procedures such as parity bits unnecessary.
