摘要:
An apparatus supporting both identification of a battery type and communications over an interface between a battery and an electronic device is disclosed. The electronic device includes a processor for communicating with communications circuitry of the battery. Identification circuitry associated with the processor enables a determination of the type of battery with which the electronic device is connected. If a “smart” battery capable of carrying out serial communications with the electronic device is connected, the electronic device further provides means for carrying out communications between the processor and the communication circuitry of the battery.

A method and apparatus for maintenance charging a battery is disclosed. A battery is fully charged using conventional CC-CV techniques and subsequently is maintenance charged by applying a first maintenance voltage to the battery for a first predetermined time period. If desired, a second maintenance voltage may be applied to the battery for a second predetermined time period. An apparatus for maintenance charging a battery utilizes a timer and a charge controller to apply a maintenance voltage to a battery for a predetermined time period.

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.

摘要:
A digitally compensated direct-conversion receiver includes devices for generating digital samples of a base-band in-phase signal and a base-band quadrature signal and for detecting the presence of a second-order product signal produced by an amplitude-modulated interfering signal. Also, the apparatus comprises a device for digitally compensating the digital samples by removing the second-order product signal, thereby producing compensated digital samples. In one method of digitally compensating samples of an information signal quadrature-modulating a carrier signal, estimated samples of a second-order product from a switched carrier signal are formed by averaging the digital samples during two time periods and by determining a time of ramps in the in-phase and quadrature signals that occur between the time periods due to the interfering signal. The digital samples may be differentiated and the results smoothed in determining the time of the ramps. In another apparatus, the estimated samples of the second-order product signal are produced by a device for averaging a square of a difference between respective digital samples of the in-phase signal and the quadrature signal, thereby determining an amplitude of the amplitude-modulated carrier signal, and a device for combining the amplitude and the digital samples, thereby generating the estimated samples.
摘要:
A method of recommending new media to a user based on various information stored and/or collected by, for example, a mobile phone is provided. More particularly, the invention provides a method of recommending new media based on information such as, for example, the content of sent and received text messages, previously viewed sound and/or video clips, location, content of emails, environmental information such as temperature or pressure, etc. Accordingly, the invention facilitates the use of information generated by a user during use of a mobile phone for recommending media to the user.
摘要:
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.
