A toothbrush apparatus includes a power source coupled to a light source for illuminating the oral cavity of the user to aid in the tooth cleaning process and prevent damage from inaccurate brushing. The light source is arranged away from the bristles and directs light towards the free ends of the bristles to aid the user in identifying areas of the teeth that may need more cleaning. In this manner, the user can more accurately clean all areas and prevent damage to the surrounding gum tissue, while directing appropriate brushing strokes to areas where food debris and plaque are present. The toothbrush may be provided in a manual or automatic version.

A power circuit in a battery powered portable communication terminal, having a battery and a transmission power amplifier for TDMA (Time Division Multiple Access) or TDD (Time Division Duplex) signals includes a power accumulator, a battery output current limiter, and a control circuit to control the current limiter and to connect the power accumulator to the battery and to the transmission power amplifier depending on whether the transmission power amplifier is transmitting a signal burst. The control circuit controls the battery to charge the power accumulator during a non-burst period. During burst periods, when the transmission power amplifier requires higher power, the control circuit connects the power accumulator to the transmission power amplifier, to supplement the current-limited current provided by the battery and provide a total current to the power amplifier that is higher than the battery output current.

A power supply apparatus has a combined power source with power cells configured electrically independently. A switch arbitrarily changes connection paths of the power cells by selectively connecting power cell terminals through switching elements. A voltage detector detects differences in electrical potentials between the power cell terminals. A controller controls ON-OFF states of the switching elements by controlling the switch by a control signal generated based on voltage signals representing the differences in electrical potentials detected by the voltage detector so as to isolate one of the power cells to stop a supply of electric power therefrom when a voltage generated in the power cell has dropped to a specified voltage or lower. The controller restarts the supply of electric power from the power cell whose power supply has been stopped when the duration of a down time of the power cell has reached a predetermined time or longer.

A progressing cavity device operates as a motor to impart torque to a bit. A stator of the device defines an internal profile having uphole stages with a first dimension being less than a second dimension of downhole stage. A rotor has an external profile with a constant outer dimension along its length. Disposed in the stator, the rotor defines cavities with the stator and is rotatable with pumped fluid progressing in the cavities from the uphole to downhole to transfer torque to the drive toward the downhole end. Although the rotor is subjected at the downhole end to a reactive torque from the bit, the interference fit of the rotor's constant dimension with the stator's downhole stages is less than with the uphole stages, which can mitigate issues with heat buildup in the downhole stages. The device can also operates as a progressing cavity pump.
