    Patent number: 5151643
    Abstract: A charging apparatus for a multiunit system includes a portable unit (101) and a base unit (103). The portable unit (101) includes first and second conductive contacts (119, 120) disposed on the portable unit (101) essentially opposite each other, and rechargable energy storage means (311) electrically coupled to the first and second conductive contacts (119, 120). The base unit (103) includes an indentation (124) formed in the base unit (103) and having a receiving surface shaped to receive at least a portion of the portable unit (101), first and second conductive protrusions (127, 129) extending outwardly beyond the receiving surface essentially opposite each other, and energy source means (131) electrically coupled to the first and second conductive protrusions (127, 129). The first and second conductive protrusions (127, 129) contact the first and a second conductive contacts (119, 120), respectively when at least a portion of the portable unit (101) is placed in the indentation (124).
