There is proposed a charging control in which a policy and charging control function provides first (preliminary) charging control information, such as PCC rules, when the communication connection is set up or modified. Then, service information can be retrieved leading to an updated set of charging control information. The policy and charging control function provides then the updated charging control information for enforcement, wherein the charging system is informed about both the preliminary nature of the first charging control information and the validity of the second charging control information for a time before the update, i.e. before the transmission of the second charging control information. The charging system can use this updated charging control information and knows that it has to replace the former charging control information, so that the charging procedure can be corrected accordingly. Thus, charging of a service miming on the communication connection on the basis of correct charging control information is possible over the complete time the service is running.

The method of charging a secondary battery includes the steps of: performing a detection of a charging rate of the secondary battery using an integrating method in which a battery capacity is calculated by integrating a current value or a power value of the secondary battery for a certain period of time, and a detection of the charging rate of the secondary battery using a voltage method in which a voltage value of the secondary battery is measured and the charging rate is calculated based on a correlation between the voltage value and the charging rate; and performing a weighted addition of the charging rate detected by the integrating method and the charging rate detected by the voltage method in accordance with the charging rate of the secondary battery, whereby detecting a final charging rate.

To provide a system, a method, and a program for enabling controls over communication sessions and charging of communication fees according to the communication sessions, which can easily be introduced to existing communication authentication systems.

A vehicle has an engine, a starter motor, an energy storage system (ESS) for powering an auxiliary system, and a supercapacitor module for powering the starter motor during engine cranking and starting. The supercapacitor module disconnects from the starter motor to recharge. A DC-DC booster converter increases the level of voltage supplied from the ESS so as to charge the supercapacitor module to a relatively higher voltage level, such as approximately 125 to 140 percent of the voltage level supplied by the ESS. A method for preventing voltage sag in an auxiliary system of the vehicle includes disconnecting the supercapacitor module from the starter motor when the engine is running, and then charging the supercapacitor module using the ESS until a cranking support voltage equals a stored target voltage. A detected commanded cranking and starting of the engine causes the connection of the supercapacitor module to the starter motor.

An apparatus senses and records consumption of medical items during performance of a medical procedure. The medical items are enclosed in wrappers having RFID tags in which medical item information is encoded. The apparatus includes a shielded enclosure that attenuates radio frequency signals emanated from RFID tags disposed outside the shielded enclosure to levels that are substantially undetectable within the internal space. RFID antennas inside the shielded enclosure receive radio frequency signals emanated from RFID tags on wrappers that are removed from used items and placed inside the enclosure. An RFID reader decodes the medical item information encoded in the RFID tags. A computer processor executes a medical item inventory module including instructions for generating a post-op list of medical items consumed during the medical procedure. Item billing information and usage trend information may be derived from the post-op list. Also, Latex alerts and item expiration alerts may be generated based on information encoded in the RFID tags.

A vibration power generator, provided with a mechanism for converting vibrational energy into electrical energy, comprises a switch for switching over whether or not power is outputted, and control of the switch is executed by periodic control thereof such that switchover occurs between respective time periods for outputting the power and respective time periods for not outputting the power at cycles not less than twice and not more than 100 times cycles of vibration. With the invention, efficiency of the generator can be enhanced, and it is possible to provide electronic equipment without power supply from outside, and capable of saving trouble of battery replacement.

A battery charger with an internal power storage device may be used to facilitate fast charging of a battery by using a high C-rate. A battery charger with an internal power storage device may include a control circuit that receives operating mode instructions to operate in a base charging mode or a fast charging mode. In the base charging mode, the battery charger may be configured to concurrently charge a battery and an internal power storage device at a base C-rate using current supplied from an external power source. In the fast charging mode, the battery charger may be configured to charge the battery at a high C-rate, which is substantially higher than the base C-rate, by using the internal power storage device. The battery charger may include an optical reader used to identify battery-specific characteristics and enable the fast charging mode.

A full charge condition of a battery is determined based on a battery temperature gradient computed at every sampling time based on two values of detected battery temperatures. However, the battery temperature detected when the level of a charge current is switched does not exhibit an accurate temperature of the battery due to contact resistance existing in contact portion of a battery side terminal and a charger side terminal, resulting in inaccurate detection of the full charge condition. A microcomputer corrects the battery temperatures detected after the level of the charge current is switched and the full charge determination is made through computation of the battery temperature gradient using the corrected battery temperatures.

Manufacturing method enabling optimal volume oil-fill even where differing from bearing to bearing due to machining fluctuations in volume-production dynamic pressure bearings. In a first charging method, injection of oil is divided into two cycles. The first is carried out under reduced pressure, following which the pressure is raised a predetermined amount to force the oil into the bearing gap. The oil-fill status is thereupon checked, the shortage is reckoned, and in the second cycle the shortage is injected. In a second charging method, in a first cycle a surplus volume is injected under reduced pressure and the pressure is raised a predetermined amount to force the oil into the bearing gap. Following that, what is in excess of the appropriate amount is removed from the bearing. The first cycle of injection and the pressure elevation may be implemented multiple times, in between which repeat pressure-reduction can be carried out.

A method and apparatus for controlling a present service charging session for charging service usage in a communication network. The method comprises receiving a first request for grant of a reservation service unit quota from a charging client, the first request including at least data identifying an account to charge for the service usage. A first granted service unit quota for the first request is determined and a first carry-over service units quota from a previous service charging session associated with the identified account is accessed. A first reservation service unit quota is determined by deducting the first carry-over service units quota from the first granted service unit quota. According to the method it is reserved for the first reservation service unit quota from the account and the first granted service unit quota is sent to the charging client. Further, a clearing request is received from the charging client including data enabling a first used amount of service units to be determined. An outstanding service unit quota is determined by deducting the first carry-over service unit quota from the first used amount of service unit and the outstanding service unit quota from the account is deducting for. An advantage is that for example mechanisms for reducing resource usage in the communication network, such as for example Quota-Holding-Time defined in 3GPP 32.299, may be used and still get a correct charging of used services thereby avoiding premature denial of service when the account is extinct.
