In an exemplary embodiment, a battery conditioning system monitors battery conditioning and includes a memory for storing data based thereon; for example, data may be stored representative of available battery capacity as measured during a deep discharge cycle. With a microprocessor monitoring battery operation of a portable unit, a measure of remaining battery capacity can be calculated and displayed. Where the microprocessor and battery conditioning system memory are permanently secured to the battery so as to receive operating power therefrom during storage and handling, the performance of a given battery in actual use can be accurately judged since the battery system can itself maintain a count of accumulated hours of use and other relevant parameters. In the case of a nonportable conditioning system, two-way communication may be established with a memory associated with the portable unit so that the portable unit can transmit to the conditioning system information concerning battery parameters (e.g. rated battery capacity) and/or battery usage (e.g. numbers of shallow discharge and recharge cycles), and after a conditioning operation, the conditioning system can transmit to the portable unit a measured value of battery capacity, for example. A battery pack having memory stores battery history and identifying data to be retrieved by a portable battery powered device. Battery status information may be utilized in conjunction with characteristic battery history data in order to optimize charging and discharging functions and to maximize the useful life of a battery pack.

Management server 16 may obtain application programs from content server 20 in response to requests of mobile terminal 11. Management server 16 may transmit the obtained application programs to mobile terminal 11 with information concerning reliabilities of the application programs.

Management of the coordinated operations of the application programs avoids problems concerning information security, where valuable information may be distributed unexpectedly because of operations of low reliable application programs. As a result, convenience of users of mobile terminals 11 can be improved without deteriorating the information security of mobile terminals 11.

An adaptive architecture for electric motors, generators and other electric machines. An adaptive electric machine provides optimal performance by dynamically adapting its controls to changes in user inputs, machine operating conditions and machine operating parameters. Isolating the machine's electromagnetic circuits allows effective control of more independent machine parameters, enabling greater freedom to optimize and providing adaptive motors and generators that are cheaper, smaller, lighter, more powerful, and more efficient than conventional designs. An electric vehicle with in-wheel adaptive motors enables delivery of higher power with lower unsprung mass, giving better torque-density. The motor control system can adapt to the vehicle's operating conditions, including starting, accelerating, turning, braking, and cruising at high speeds, thereby consistently providing higher efficiency. A wind powered adaptive generator can adapt to changing wind conditions, consistently providing optimal performance. An adaptive architecture may improve performance in a wide variety of electric machine applications, particularly those requiring optimal efficiency over a range of operating conditions.

In many cellular systems, reusing spectrum bandwidth, creates problems in boundary regions between the cells and sectors where the signal strength received from adjacent base stations or adjacent sector transmissions of a single base station may be nearly equivalent. The invention creates a new type of diversity, referred to as multiple carrier diversity by utilizing multiple carriers, assigning different power levels to each carrier frequency at each base station, and/or offsetting sector antennas. The cell and/or sector coverage areas can be set so as to minimize or eliminate overlap between cell and/or sector boundary regions of different carrier frequencies. Mobile nodes traveling throughout the system can exploit multiple carrier diversity by detecting carriers and selecting to use a non-boundary carrier based on other system criteria in order to improve performance. Boundary carriers may, but need not be, identified and excluded from consideration for use by a wireless terminal.
