AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 4, 5, 11-18 and 20-23 is confirmed.
Claims 1-3, 6-10 and 56-58 are now disclaimed.
Claims 28-32 and 38-55 are cancelled.
Claims 19, 24, 33 and 36 are determined to be patentable as amended.
Claims 25-27, 34, 35 and 37, dependent on an amended claim, are determined to be patentable.
11. A power device for supplying power to a portable rechargeable electronic device, the power device comprising:
a first portion for receiving electrical input power from a source, the input having an input voltage;
a second portion for delivering electrical output power to the electronic device, the output power having an output voltage;
circuitry for converting the input power voltage to the output power voltage and for determining an “off” state of the circuitry;
a connector located on the second portion and removably connectable with the electronic device; and
a switch assembly having powered terminals, the switch assembly responsive to movement or at least a movable portion thereof to electrically connect the terminals and to provide an output signal to activate the circuitry to the “on” state,
wherein the circuitry automatically turns the circuitry to the “off” state, the circuitry drawing no power when in the “off” state.
19. The power device of claim 11 wherein the circuitry includes a solid state switch element [ latching relay ] that opens in response to the output power being at or below a threshold power level to change the circuitry to the “off” state.
24. A power device for supplying power to an electronic device, the power device comprising:
a first portion for receiving electrical input power from a source, the input having an input voltage;
a second portion for delivering electrical output power to the electronic device, the output power having an output voltage;
power circuitry for converting the input power voltage to the output power voltage and for determining an “off” state of the power device;
switching circuitry operable to electrically activate the power circuitry to the “on” state; and
a load sensing portion operable to sense one or more pulses and determine the power or load being drawn from the power device by the electronic device based thereon [ , the load sensing portion determining the power or load being drawn from the power device by measuring the frequency of the pulses] .
33. The power device of claim 24, wherein the load sensing portion measures the [ frequency of ] pulses from transformer control circuitry which controls a power state of a transformer of the power device.
36. The power device of claim 24 [ 33 ] further comprising transformer control circuitry for controlling a power state of a transformer of the power device, wherein the transformer control circuitry and the load sensing portion are incorporated onto a single integrated circuit.
