  • Publication number: 20240380086
    Abstract: The present invention relates to a single cell cylindrical battery, such as a button cell or a button battery, that can be regarded to have the shape of a slice of a cylinder, and to a method preventing upper digestive and upper respiratory tract injury after accidental ingestion of the single cell cylindrical battery. It is noted that in some case ingestion has even led to the death in particular of children or small size adults, or people with a mental limitation, or people with a prior narrowing of structures in which the battery can be lodged. The structures in which the battery can be lodged are both the pharyngeal, upper digestive and upper respiratory tracts. As ingestion itself can not always be prevented, a relatively safe battery has been developed, which mitigates problems associated with ingestion.

  • Patent number: 11973476
    Abstract: Chopper amplifiers with low intermodulation distortion (IMD) are provided. To compensate for IMD, at least one distortion compensation channel is included in parallel with chopper amplifier circuitry of a main signal channel. Additionally, output selection switches are included for selecting between the output of the main signal path and the distortional compensation channel(s) over time to maintain the output current continuous. Such IMD compensation can be realized by filling in missing current of the main signal channel using the distortion compensation channel(s), or by using channel outputs only when they have settled current.
