Abstract: A vehicle such as an aircraft (400) is provided (101) with a source of power having a power output such as a source of light (401). This power output can then be combined with an identifier (103, 416) that is substantially unique to the aircraft. An optical conduit (405) can then be used (104) to couple this source of light to a light-to-electricity conversion apparatus (406). So configured, the optical conduit delivers light from this source of light to the light-to-electricity conversion apparatus such that the light source then serves as a source of electricity in the vehicle and as a source of a substantially unique identifier as corresponds to the vehicle is available for such use as may be appropriate.

Abstract: A method of transmitting data in a wireless power transmission system comprising a power transmitter including a first and a second light source and means for directing the emitted light. The second light source is used for transmitting, parallel and as low-intensity pulses, light arranged around the light emitted by the first light source, data bits being encoded in the pulses so as to determine a maximum time interval between two successive pulses. At least one power receiver of the system comprises a first and a second photo-detector for receiving the emitted light and for converting it into electric current. The second photo-detector is used for indicating light pulses and data included therein and time between successive light pulses. A control signal indicating disturbance-free reception of data is transmitted to the transmitter if the time between successive light pulses does not exceed a predetermined maximum time interval.

Abstract: A method for wireless power transmission in a system comprising a power transmitter which in turn comprises a first light source and means for directing the light emitted by the first light source to a desired direction, and at least one power receiver comprising a first photo-detector for receiving the emitted light and for converting it into electric current. A second light source included in the power transmitter is used for transmitting light around the light emitted by the first light source and substantially parallel to it, the intensity of the light being lower than that of the light emitted by the first light source. A second photo-detector included in the power receiver is used for detecting the light emitted by the second light source and for transmitting a control signal to the power transmitter in response to a successful reception of the light emitted by the second light source. The first light source of the power transmitter is switched on in response to the reception of the control signal from the power receiver informing of the reception of the light emitted by the second light source.

Abstract: A fiber-optic data-link used to interface a remote process variable sensor/transmitter to a local process control system includes a local light source module and a remote interface module interconnected by one or more optical fibers. Energy for operating the remote interface module and its associated process variable sensor/transmitter is provided by light energy transmitted from the local site to the remote site and converted at the remote site to an electrical signal. The local light source module and the remote interface module each may include a microcontroller. The controllers not only control the flow of status messages in either analog or digital or analog and digital form simultaneously from the remote site to the local site, but also insure the integrity of the system and minimizes the amount of optical power delivered to the remote site to that which is required to electrically power the remote interface module and the process variable sensor/transmitter, thus extending the useful life of the light source. The system is also arranged to check the integrity of the optical fibers to ensure that the light intensity is always below a minimum eye-safe value whenever the optical fiber is not correctly connected between the local light source module and the remote interface module.

Abstract: A self biased isolated remote switch (11) for electrically isolating a switch (24) from a circuit (16). The circuit (16) is coupled to the primary side of the self biased isolated remote switch (11) while the switch is coupled to the secondary side.

Abstract: A method and apparatus for transmitting data between two transmission-receiving units with infrared signals wherein one of the two transmitting receiving units does not have its own power supply and is to be supplied with energy by light received with photocells. When the data receiver and energy receiver are in close proximity, blooming of the data can occur and, thus, faulty data transmission results. In the invention, the data and energy are intermittently and alternately transmitted such that during the energy transmission the data transmitter of the first transmitting receiving unit sends out auxiliary synchronization pulses and after predetermined time both the energy transmission as well as the auxiliary transmission pulses are simultaneously shutoff. The trailing edges of both pulses can be unambiguously recognized even during blooming and are used as a synchronization signal which causes the second transmitting receiving unit to start sending data.
