Abstract:
A multi-functional mobile station (MMS) (610B) associated with at least one public land mobile network having switching circuitry implemented with a first cross-connect base-band switch system (370A, 370B) and a second cross-connect base-band switch system (365A, 365B). The first cross-connect base-band switch system (370A, 370B) is for selectably effectuating a first connection between an external receiver and at least one of the transceiver and the microphone of the MMS. The second cross-connect base-band switch system (365A, 365B) is for selectably effectuating a second connection between an external transmitter and at least one of the transceiver and the speaker (350) of the MMS (610B). The MMS (610B) is adapted to include one output node (335) for establishing the first connection and one input node (340) for establishing the second connection.
Abstract:
A method and apparatus for providing enhanced accessory support in a portable communication apparatus (10) primarily adapted for telecommunication is disclosed. An external accessory device (22) is attached to the portable communication apparatus (10) having a display (12) with a visual presentation area. Accessory information is sent from the external accessory device (22) to the portable communication apparatus (10) and the received accessory information is displayed in a subarea (54) of the display (12).
Abstract:
There is described a system for storing information, using a mobile communications device such as a mobile phone. The phone has connection to a network infrastructure, over a mobile communications network such as a cellular radio network. Information can be stored by the user either in a storage location within or attached to his phone, or in a storage location which forms part of the network infrastructure. The user can be given the option of selecting a preferred storage location, but the system can also be transparent, so that the user does not need to know where any specific item is being stored. Similarly, information can be retrieved by the user, without the user needing to know where the information was stored.
Abstract:
A microphone is provided in a mobile terminal and is connected to a current source when the flip portion of the mobile terminal is open and is disconnected from the current source when the flip portion of the phone is closed. The mobile terminal can then infer the position of the flip portion of the housing, e.g, opened or closed, based upon the state of the microphone's current supply circuit, for example by detecting the current flowing through the circuit or a voltage drop across a supply resistor. In addition, an on-hook/off-hook button can be provided to a hands-free accessory without increasing a number of signal lines/connections between the hands-free accessory and the mobile terminal. This can be accomplished, for example, by connecting the on-hook/off-hook button to a switch in the microphone signal line. The switch selectively creates an open in the microphone signal line, which can be detected by the mobile terminal, thereby resulting in an off-hook condition. In addition, an interface between a mobile terminal and other auxiliary or accessory devices can be generalized to accommodate either digital or analog signaling without an increase in the number of pins/signal lines associated with the interface.
Abstract:
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.
Abstract:
A method, system, and apparatus enables an electronic device in communication with an accessory to accurately report a remaining battery life when the accessory provides information relating to a power usage to the electronic device. In one embodiment, the accessory draws power from a battery of the electronic device, and the electronic device is able to more accurately estimate a remaining battery life by considering the power usage information provided from the accessory. The electronic device may thereafter indicate to a user the remaining battery life. In one alternative of this embodiment, the information relating to the power usage is in the form of a current consumption of the accessory. In another embodiment, the electronic device indicates a remaining battery life of a battery of an accessory.
Abstract:
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.
Abstract:
Method and apparatus for synchronizing communication between a battery and an electronic device are disclosed. Bytes consisting of a number of bits are transmitted between the electronic device and the battery. A predetermined bit sequence is appended to at least some of the bytes prior to transmission. The time interval between given shifts in the predetermined bit sequence is used to synchronize the communication.
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.
