Abstract
Abstract Remotely actuated power control apparatus having a control signal processing circuit which receives a remote control signal emitted from a remote transmitter and controls a power switch of an electronic instrument. The control apparatus includes a battery connected to the remote control signal processing circuit for supplying an operating voltage to the latter, and it also includes a power supply circuit connected to the electronic instrument substantially in parallel thereto, whereby an electronic power of the electronic instrument is controlled ON and OFF by the power switch.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A remote power control apparatus comprising: a. a remote control signal processing means comprising a remote control signal receiving circuit, a switch to connect said apparatus to an external power source only when said switch is closed, and a control circuit actuated by signals from said receiving circuit to close said switch; b. a battery connected to said remote control signal processing means for supplying an operating voltage to said remote control signal processing means; c. a power supply circuit for said remote control signal processing means, said power supply circuit comprising an input section connected to said switch to be energized from said external power source, and a rectifier section connected to said remote control signal processing means to supply operating power thereto when said switch is closed; and d. an electronic instrument comprising a power supply connected to said switch to be energized from said external power source through said switch controlled by said remote control signal processing means.
Claim 2
Dependent Claim
161 words
A remote power control apparatus comprising: a. a remote control signal processing means comprising a remote control signal receiving circuit, a switch to connect said apparatus to an external power source only when said switch is closed, and a control circuit actuated by signals from said receiving circuit to close said switch; b. a battery connected to said remote control signal processing means for supplying an operating voltage to said remote control signal processing means; c. a power supply circuit for said remote control signal processing means, said power supply circuit comprising an input section connected to said switch to be energized from said external power source, and a rectifier section connected to said remote control signal processing means to supply operating power thereto when said switch is closed; and d. an electronic instrument comprising a power supply connected to said switch to be energized from said external power source through said switch controlled by said remote control signal processing means.
Claim 3
Dependent Claim
33 words
