Abstract: A battery indicating its own power level and temperature includes a transparent enclosure, a first, a second, and a third switch, a first, a second, and a third lighting member coupled to the first switch and a main chip. The main chip switches on the first and second switches to enable visible color indications of two different power states of the battery, and switches on the third lighting member to indicate with color a high battery temperature, all colors being visible through the transparent enclosure.

Abstract: An apparatus for indicating power level of battery includes a computer base, a cover pivotally mounted to the computer base, and a battery module mounted to the cover. The battery module includes a battery volume calculating chip and a first battery. The battery volume calculating chip includes a first power level detecting pin. An anode of the first battery is electrically coupled to the first power level detecting pin. A cathode of the first battery is grounded. The battery volume calculating chip detects power level information of the first battery by the first power level detecting pin. The battery volume calculating chip calculates power level of the first battery according to the power level information, and transmits power level of the first battery to the computer base by the data signal output pin. The computer base displays power level of the first battery on the battery module.

Abstract: A mobile phone receiving bag severs for shielding electromagnetic wave. The mobile bag receiving bag comprises a receiving bag having a hollow space for receiving a mobile phone; a shield unit installed at one lateral surface of the receiving bag at a position adjacent to a user's waist as it is worn the receiving bag on the waist. The shield unit is selected from one of metal fibers, conductive materials or other material having functions of absorbing or decaying or shielding electromagnetic waves. The shielding unit is integrally or separately formed with the receiving bag. An earphone bag is further added to the receiving bag. The earphone bag is separable from the receiving bag; strong magnets or fastener tapes or buckles are installed to the earphone bag and receiving bag so that the earphone bag and receiving bag are attractable to one another.

Abstract: A flexible seal for use in a solid oxide fuel cell stack is formed from a ceramic fibre matrix impregnated with a plurality of metallic or semi-metallic particles which are then converted to a corresponding ceramic particle, such as by oxidation. The seal may be formed by dipping the fibre matrix into a slurry, suspension or sol-gel of the particles in an alcohol, and then firing the seal to oxidize the metal particles. The seal may also be formed by tape casting a slurry formed from metallic or semi-metallic particles, ceramic fibres and/or ceramic particles.
