Abstract: An improved cathode film is formed by forming a copolymer of 10 to 90 mol percent of a fluorinated ethylene copolymer such as tetrafluoroethylene soluble in an organic solvent such as acetone. An ionically conductive salt such as potassium trifluorosulfonate is added to a solution of the copolymer. The solution is applied to particles of active cathode material such as AgO. The solvent is removed to form a film which can be pressed onto a current collector.

Abstract: A battery charging system comprising: a current source; a battery; and a voltage and current regulator, which regulates voltage applied to the battery and current supplied to the battery. The battery charging system shapes the current supplied to the battery, and may be used to taper the current supplied to the battery. The voltage and current regulator may comprise: an adjustable band-gap voltage reference diode, a potentiometer, a resistor, and a transistor, or an adjustable shunt regulator, and a transistor operating in conjunction with the adjustable shunt regulator, or other suitable voltage and current regulator means. The battery charging system regulates the current flow supplied to the battery, which originates from a constant charging current source. As the battery voltage exceeds a predefined terminal voltage, the battery charging system diverts charging current through a transistor, thus clamping the battery at the terminal voltage and shaping the current supplied to the battery.

Abstract: A mobile communication device includes infrastructure capable of processing streamed multimedia data in a single threaded operating environment. The infrastructure comprises a central processing unit (CPU), an operating system (OS), and a digital signal processor (DSP) operatively coupled to the CPU. A high level application is coupled to the CPU via a memory bus. The high level application is given direct access to the DSP. The high level application instructs the CPU to display a first downloaded image in a slide show format, and hand over audio processing of an associated first downloaded sound clip to the DSP. The CPU is free to immediately download a successive image and a successive associated sound clip, thereby creating the appearance of processing the multimedia data stream in a multithreaded mode.
