Abstract
Official abstract text for this publication.
A reflector for use in a reflex mode detection device, said reflector being positioned in alignment with a detector and including a reflective region for reflecting a light beam to send the light beam back towards the detector, a signalling interface configured to indicate a state of alignment of the reflective region of the reflector with respect to an emitter, a detector configured to detect the presence of the light beam against the reflector, interpretation circuitry configured to control the signalling interface to indicate the state of alignment, and a power supply having autonomous electric power and configured to supply electric power to the signalling interface and the interpretation circuitry.
First claim
Opening claim text (preview).
The invention claimed is: 1. A reflector for use in a reflex mode detection device, said reflector being positioned in alignment with a detector and comprising: a reflective region for reflecting a light beam to send the light beam back towards the detector; a signalling interface configured to indicate a state of alignment of the reflective region of the reflector with respect to an emitter; a detector configured to detect the presence of the light beam against the reflector; interpretation circuitry configured to control the signalling interface to indicate the state of alignment; and a power supply having autonomous electric power and configured to supply electric power to the signalling interface and the interpretation circuitry. 2. The reflector according to claim 1 , wherein the detector and the power supply are photovoltaic cells sensitive to the light of the light beam, distributed over a first region corresponding to the reflective region. 3. The reflector according to claim 2 , wherein the detector and the power supply are photovoltaic cells sensitive to the light of the light beam, distributed over a second region peripheral to the first region. 4. The reflector according to claim 2 , wherein the power supply is photovoltaic cells sensitive to ambient light, distributed over a second region peripheral to the first region. 5. The reflector according to claim 1 , wherein the detector is photoreceptors arranged over a first region peripheral to the reflective region. 6. The reflector according to claim 5 , wherein the power supply is photovoltaic cells sensitive to ambient light, distributed over a second region peripheral to the first region. 7. The reflector according to claim 1 , wherein the signaling interface includes light indicators. 8. A reflex mode detection device comprising: a detector; and a reflector as defined in claim 1 .
