20140160575 | Optical surface, lens and reflector - The present invention provides an optical surface which is able to mix different wavelengths into a light pattern which contains all wavelengths evenly distributed across the pattern. The novel optical surface extends in at least two Cartesian base dimensions (X, Y), whereby a cross-section of the surface taken in either of said two Cartesian base dimensions (X, Y) features a first plurality of protuberances which extend to the same direction in a third Cartesian dimension (Z). The cross-section of the optical surface also features a second plurality of protuberances which extend to the opposite direction as the first plurality of protuberances in the third Cartesian dimension (Z). The pluralities of protuberances form converging and diverging optical shapes for mixing different wavelengths scattering from the optical surface. | 06-12-2014 |

20110249437 | HIGHLY EFFICIENT LED ARRAY MODULE WITH PRE-CALCULATED NON-CIRCULAR ASYMMETRICAL LIGHT DISTRIBUTION - A light module includes a light emitting diode (LED) array and a double-reflective assembly coupled to the LED array. The double-reflective assembly includes a lower member having a frame. The frame has an opening corresponding to the LED array. The frame and LED array are located in the same plane. The light module further includes a left bottom reflector and a right bottom reflector. The light module further includes an upper member which includes a left top reflector; and a right top reflector, wherein the left top reflector is attached to the left bottom reflector, and right top reflector is attached to the right bottom reflector, each forming an arbitrary left and right double-reflective assembly. A shape geometry and profile of each double-reflective assembly provides a pre-calculated combined non-circular asymmetrical intensity distribution pattern. The intensity distribution pattern is a superposition of light reflected from the bottom reflectors, light reflected from the top reflectors, light doubly reflected from both the top and bottom reflectors, and light directed into the intensity distribution pattern directly from the LED array. | 10-13-2011 |

20140305338 | AGENT FOR PAINT AND METHOD FOR MANUFACTURING THE PAINT WITH THE AGENT - The agent of a biological paint, such as of the paint sold under the trademark Bioboya, is a mixture comprised of water, saccharose, animal oil and/or a root plant oil, vegetable oil, wet wax, clay and silicon, into which a biological paint is combined according to the method. With an ecological indoor paint with the agent added, environmentally benign and safe properties are achieved: non-combustibility and biodegradability. Also, the paint with added agent does not produce gases and is suited, in addition to concrete surfaces, also to wood surfaces, metal surfaces, Styrox surfaces, gypsum board surfaces and plastic surfaces. | 10-16-2014 |

20110225304 | SYSTEM AND METHOD FOR ESTABLISHING AND MAINTAINING A VOICE OVER INTERNET PROTOCOL CONNECTION BETWEEN WIRELESS DEVICES - A system and method for establishing and maintaining a voice over internet protocol connection between wireless devices, in one example embodiment, may comprise a receiving module to receive a communication device identifier, and a request to establish a communication data link to another communication device. The communication device identifier may initially be received by a terminal from the communication device over a wireless data link connecting the communication device and the terminal. Subsequently, the terminal network address may be associated with the terminal, which received the communication device identifier. A processing module may be utilized to determine whether another communication device is reachable over a wireless data link to another terminal based on information stored in a register. Further, a communication module may be utilized to establish the communication data link between one communication device and another communication device subsequent to determining that another communication device is reachable by a terminal over the wireless data link. | 09-15-2011 |
20120309386 | SYSTEM AND METHOD FOR ESTABLISHING AND MAINTAINING A CONNECTION BETWEEN DEVICES - A system and method to establish and maintain a connection between devices, which in one example embodiment of a method, may comprise receiving a request to establish a connection between a first communication device and a second communication device. A determination is made as to whether the second communication device is reachable via a data network. Based on the determination that the second communication device is reachable over the data network, a connection between the first communication device and the second communication device is established via the data network. Based on the determination that the second communication device is not reachable over the data network, a connection between the first communication device and the second communication device is established via a telecommunications network.
