| 101 | Arrangement for wireless earphones without batteries and electronic circuits, applicable in audio-systems or audio-visual systems of all kinds | EP88600004.1 | 1988-03-21 | EP0296092A2 | 1988-12-21 | Geladakis, George |
The present invention relates to an arrangement for wireless earphones applicable in audio - systems or audio - visual systems of all kinds. The present invention overcomes the problem of the high construction, installation, operation, repair and maintenance cost of the wireless earphones of the prior art, due to the batteries and electronic circuits employed by the same, by means of a new system of wireless earphones without batteries and electronic circuits, whose operation is based on the inductive coupling between a space coil and an earphone coil, where the order of inductive coupling depends on the height of installation of the space coil, the circumferential length and number of turns of the two coils, the kind of used cores in the coils (air - or magnetic materials) and specific resistances of the materials used. |

A method for using an underground mine communication system to effect minewide communication and an intrinsically safe current limiter circuit for insuring that electrical equipment in the system will not cause incendiary conditions. The underground mine communication system comprises a plurality of repeaters (28) and medium frequency radios, including mobile (24), portable and personal-carried radios (26), coupled to electrical conductors (32) and natural waveguides existing in the earth by tuned loop antennas. Messages transmitted by the radios are carried to the repeaters by the conductors or coal seam waves. The repeaters amplify, replicate and retransmit the message at two different frequencies for transmission of the message to a surface base station and to other radios in the system. A paging system, which has a separate set of repeaters (29), is also coupled to the network of electrical conductors and natural waveguides by tuned loop antennas. The paging system alerts miners to contact the surface base station. Radios, pagers and repeaters in the system are equipped with the intrinsically safe current limiter circuit to preclude the development of incendiary conditions. The current limiter circuit comprises a series arrangement of a current trip circuit, a redundant current trip circuit and a current limiting field effect transistor controlled by a feedback control amplifier. |

| Various energy harvesting and control techniques are used to power and control electronic accessories from the audio output channels and microphone input channel of mobile digital devices while preserving audio input and output functionality. One technique uses one of the stereophonic audio channels to generate power, and the other in conjunction with the microphone jack to enable bi-directional communications while preserving audio input and output. Another technique allows a low powered electronic accessory with bi-directional communications to be supported while simultaneously supporting audio input & stereo output. These techniques facilitate the ability to play music, narration and instruction and to receive oral responses and instruction with no perceived loss or gaps, even while using the audio jack of a mobile digital device to harvest energy and bi-directional communication. | ||||||

| A receiving antenna circuit is arranged in a reactive near-field of a modulated magnetic induction signal and forms a narrow band-pass filter. The output of the antenna circuit is not subjected to any frequency translation prior to digitizing, and the signal may nevertheless be digitized with low resolution, which radically reduces the power consumption of the receiving circuits. The reduction in power consumption is of several orders of magnitude, which allows implementation of such receiving circuits in battery-driven devices such as hearing devices without substantially affecting the battery life. | ||||||

| 117 | User authentication using near field communication | US13399569 | 2012-02-17 | US09231660B1 | 2016-01-05 | Andrew Foster |
| A mobile computing device is authenticated to a user using an NFC tag embedded within or attached to an object that is commonly carried or worn by the user. The NFC tag may be initially associated when an NFC reader of the device senses the NFC tag and wirelessly retrieves a tag identifier from the tag. The tag identifier is stored for subsequent retrieval. The authentication process begins by positioning the device proximate the object such that the NFC reader of the device retrieves the tag identifier from the NFC tag. In the event that the retrieved tag identifier matches the stored tag identifier, the mobile computing device is unlocked and the user may access the mobile computing device. If the retrieved tag identifier does not match the stored tag identifier, the user is not authenticated and the mobile computing device remains locked. | ||||||
