摘要:
A server receives a request for transfer or streaming of a data file sent in the local network from a portable communication device. The server provides the portable communication device with an identifier allowing the data file to be located on the server via a wide area network and transfers or streams the file over the local network to the portable communication device.

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.
摘要:
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.

An apparatus receives a reference clock signal that is then applied to a first one of a number of series-connected controllable delay stages. The output of each delay stage is a further delayed version of its input, the amount of delay being controlled by a control signal. A phase relation between a first preselected one of the plurality of delayed reference clock signals and a second preselected one of the plurality of delayed reference clock signals is measured. Alternatively, it may be a phase relation between the reference clock signal and a preselected one of the plurality of delayed reference clock signals that is measured. The measured phase relation is compared with a desired phase relation, and the difference is an error signal that is fed back to the delay stages for use as the delay control signal. In this manner, the delayed reference clock outputs from the delay stages lock in to a very stable desired phase relation with respect to one another. The delayed reference clocks are then transformed by logic circuitry into nonoverlapping phase clocks for use by a switched capacitor sigma-delta modulator. By using the clocks generated in this manner, the switched-capacitor sigma-delta modulator may be operated at rates of 13 MHz or higher.
摘要:
A method and system that makes use of social networking data and/or sensor data gathered from personal mobile radio terminal-based sensors (36-48) and/or advertisement display (14) based sensors to select and to serve relevant messages to render to a group of individuals. The messages are chosen to maximize the impact the messages will have on the target audience based on the likes/dislikes of the crowd, any mood the individuals may be experiencing, or any other relevant data.

摘要:
Method and system for communication between a battery power receiving device and a battery pack are disclosed. The battery power receiving device has a battery information circuit that is carried with the battery power receiving device as a single unit. Battery information such as battery identification and capacity are stored in the battery power receiving device and the battery information circuit. The battery power receiving device uses the battery information if the battery identification stored therein coincides with the battery identification stored in the battery information circuit.
摘要:
A data and message retrieval communications system utilizes a base station such as a PC or cellular phone to transmit received messages and stored data in accordance with an operator customized data configuration and transmission scheme. The system includes a remote receive-only communication unit that receives and processes the signal from the base station in accordance with an operator customized data configuration and retrieval scheme. The remote unit preferably includes a receiver having an antenna, a processor that processes the transmission signal received by the receiver, a memory storing the personal data and data corresponding to the transmission signal, and a display interface unit enabling an operator to interface with the processor programmed to access and control the receiver, the memory and the display interface in accordance with the operator customized data configuration and retrieval scheme. In one arrangement, the remote communication unit is embodied in a wristwatch for maximum portability.
