A control apparatus for a vehicular power transmitting system including (a) an electrically controlled differential portion operable to distribute an output of a drive power source of a vehicle to a first electric motor and a power transmitting member, (b) a second electric motor connected to a power transmitting path between an output shaft of the drive power source and a drive wheel of the vehicle, (c) a coupling device provided in the electrically controlled differential portion and operable to selectively switch the differential portion between a differential state and a non-differential state, and (d) an electric-energy storage device operable to store and discharge an electric energy supplied from the first or second electric motor, the control apparatus including a torque-receiving-proportion control portion configured to control a proportion of torque values of a reaction torque corresponding to a torque acting on a predetermined member of the electrically controlled differential portion, which torque values are respectively received by the first electric motor and the coupling device, such that a ratio of the torque value received by the coupling device, with respect to the reaction torque, increases with an increase of a difference of an electric energy amount consumed by the second electric motor from an electric energy amount generated by the first electric motor.

In a building fire alarm system, the light strobes of a network of strobes are synchronized to flash simultaneously. Each strobe has a charging circuit to charge a capacitor which discharges through a flash tube. Once a capacitor is charged, the charging circuit is disabled. A synchronization pulse is applied through common power lines to trigger discharge of each strobe capacitor through the flash tube followed by recharging of the capacitor.

A method of host development is based on paying the writer of free content through advertising revenue sharing. Steps include receiving an advertisement, which is paid content, from an advertiser; receiving non-paid content subject to a condition that the provider may receive no compensation for the non-paid content; combining the paid content and the non-paid content on a content page; registering a user to interact with the content page; sending the content page for display on a computer operated by the user; calculating a number equaling all interactions of the user with the paid content; receiving payment from the advertiser for said number; and paying the provider based on a fraction of the payment.

A protection circuit of a secondary battery includes a thermal switching element which has an resistance that decreases along with increase of temperature and which is connected in parallel with the secondary battery.

A system and method for effectively managing operating power for an electronic device may include a battery pack coupled to the electronic device for supplying operating power to the electronic device. A battery controller may be configured as a single integrated-circuit device to alternately manage the battery pack either in a single-cell implementation or in a dual-cell implementation. The battery controller may include a charge pump device to provide an internal controller power supply for operating the battery controller in the single-cell implementation.
