TRANSFER OF POWER AND DATA
First Claim
1. A method for transmission of power and data during a plurality of consecutive time intervals, the method comprising:
- during a power-transmission portion of each of the plurality of consecutive time intervals, transmitting a power signal in which no data is encoded; and
during a power-and-data-transmission portion of each of the plurality of consecutive time intervals, transmitting a power-and-data signal in which is encoded a single bit, the power-and-data signal including;
(a) a high-level power-and-data signal portion, and (b) a low-level power-and-data signal portion.

Abstract
Apparatus and methods are described, including a method for transmission of power and data during a plurality of consecutive time intervals. During a power-transmission portion of each of the plurality of consecutive time intervals, a power signal, in which no data is encoded, is transmitted. During a power-and-data-transmission portion of each of the plurality of consecutive time intervals, a power-and-data signal, in which is encoded a single bit, is transmitted. The power-and-data signal includes: (a) a high-level power-and-data signal portion, and (b) a low-level power-and-data signal portion. Other applications are also described.

52. Apparatus for transmission of power and data during a plurality of consecutive time intervals, the apparatus comprising a transmitter comprising:
-
a processing unit, configured to output a sequence of bits; a modulating unit, configured to convert the sequence to an analog signal; and a light source, configured to transmit a light signal in response to the analog signal, the light signal including; during a power-transmission portion of each of the plurality of consecutive time intervals, a power signal in which no data is encoded, and during a power-and-data-transmission portion of each of the plurality of consecutive time intervals, a power-and-data signal in which is encoded a single bit, the power-and-data signal including;
(a) a high-level power-and-data signal portion, and (b) a low-level power-and-data signal portion. - View Dependent Claims (53, 54, 55, 56, 65, 68, 72, 77, 78, 81, 84, 85, 86)
