    摘要: The present invention discloses a system and apparatus for a wall-mounted back-scrubbing and massaging apparatus for scrubbing and exfoliating difficult to reach back areas. The system has a wall mounting plate that is removably attachable to a wall surface with an attaching means. A scrubbing means on a skeleton rubber frame is mounted onto the wall mounting plate, and a scrubbing means, preferably a loofah, is removably attached to a scrubbing means mounting surface on the skeleton frame. The loofah is in a position for convenient scrubbing of a person's skin when brought into contact with the loofah. In a further embodiment of the invention, the method of using the apparatus is simple: using leaning and body movement to obtain cleansing effect on the back by the users, including people with disabilities.

    摘要: An analog to digital converter system includes first and second delta sigma converters, a calculation engine, and a serial interface on a single chip. The calculation engine is configured to calculate energy, power, rms current and voltage for single phase 2 or 3 wire power meters. Voltage and current are measured with a shunt or transformer, and a divider or transformer, respectively. The serial interface is bidirectional for communication with a microprocessor or controller, and provides a fixed width programmable frequency output proportional to energy. The digital converter system is user system calibratible.
