Abstract: A method for purifying phycocyanin from a phycocyanin-containing solution is provided. The method comprises a first step of partially purifying the solution by aqueous two-phase separation (ATPS) and a second step of purifying the phycocyanin by ammonium sulfate precipitation. The purified phycocyanin product can in some cases be of a sufficiently pure grade to be used as a food or cosmetic pigment.

Abstract: A light sterilizer comprising: (a) an ultraviolet-C (UVC) light secured to a light printed circuit board assembly (PCBA), wherein the UVC light projects a sterilizing zone to sterilize objects or surfaces within the sterilizing zone; (b) a heat sink positioned adjacent to and in contact with the UVC light, wherein the heat sink is mounted to the light PCBA; and (c) a fan positioned adjacent to the heat sink; wherein the UVC light sterilizes viruses within the sterilizing zone by breaking the virus molecules.

Abstract: An illuminated automotive badge is described. The illuminated automotive badge comprises an emblem, a light guide, and an LED assembly. The LED assembly may comprise a plurality of LEDs attached to a mount. A light guide may be disposed over the LED assembly. The light guide has optical properties that spread the light emitted from the LEDs to the edges of the emblem. As such, the light emitted by the LEDs provides an indirect light source for illuminating the emblem. The illuminated automotive badge may further comprise a housing configured to block stray light.

Abstract: This invention is about using a projector to monitor doors, provide networkable or non-networked security, and perform vehicle-to-vehicle and/or vehicle-to-person communication. The embodiments and purposes may be employed without a network connection and without a dedicated display component or screen.

Abstract: An illumination device projects light in a predetermined illumination pattern on a surface. The illumination device includes a housing having a cavity and an aperture that opens into the cavity. The illumination device further includes a light module operatively attached to the housing for selectively emitting the light into the cavity. Furthermore, the illumination device includes a digital light panel at least partially disposed in the cavity between the light module and the aperture. The digital light panel has at least one opening defining a base pattern configuration corresponding to the predetermined illumination pattern for aligning the light emitted from the light module through the opening into the base pattern configuration and subsequently projecting the light through the aperture onto the surface in the predetermined illumination pattern.

Abstract: A system receives, from a text device, an emergency call placed by a hearing-impaired party, the emergency call being associated with information identifying a location of the text device. The system also identifies a public safety answering point (PSAP) based on the location information. The received emergency call may be forwarded to the identified PSAP.

Abstract: A method of producing an array of islands (12) on concentric tracks (13) on a rotating substrate by selective exposure of an electron-sensitive surface of the substrate to an electron beam comprises directing the beam onto a point (A) on the surface within a zone of action of the beam and deflecting the beam in the sense (31) of substrate rotation to remain on the point until the point (A?) has received an electron dose from the beam. The beam is then redirected onto a further point (B or T) at a spacing from the preceding point (A?) and dosed by the beam in similar manner. The redirection and deflection procedure is repeated for at least one substrate revolution, preferably several revolutions, so that points are dosed along at least one of the tracks (13a), preferably several of the tracks (13a to 13j).

Abstract: A method for providing communication services for the hearing-impaired may include receiving a telephone call from a hearing-impaired party or a hearing party. The method may also include forwarding the telephone call to a communication assistant and establishing a communication link, such an Internet protocol link, that links the hearing-impaired party, the communication assistant and the hearing party.

Abstract: A modular personal audio set and related system of use is disclosed. The modular personal audio set has a connector for detachably securing different mating-fittings for engaging jacks of different audio products is disclosed. Preferably, the personal audio set is a headset and the connector is positioned along a wire that extends from the mating fitting to the audio driver of the personal audio set. More preferably, the connector also has a microphone and microphone activation button thereon.

Abstract: A method for providing communication services for communications between a hearing-impaired party and a hearing party includes establishing a voice link with the hearing party. The method also includes receiving a voice message from the hearing party via the voice link and generating a text message corresponding to the voice message using voice recognition. The method may also include transmitting the text message to the hearing-impaired party. Optionally, a high speed text input device may also be used with, or instead of, the voice recognition to generate the text message.

Abstract: A method for providing communication services for the hearing-impaired includes establishing a communication link between a hearing-impaired party and a communication assistant. The communication link may be a full duplex link. The communication assistant may also establish a voice link with a hearing party. The hearing-impaired party and the hearing party may then communicate, with the communication assistant acting as a conduit for the conversation. For example, the hearing party may send a voice message to the communication assistant. The communication assistant may then convert the voice message into a text message and transmit the text message to the hearing-impaired party. The communication assistant may also convert text messages received from the hearing-impaired party into voice messages for the hearing party.

Abstract: A method for providing communication services for the hearing-impaired includes establishing a communication link between a hearing-impaired party and a communication assistant. The communication assistant may also establish a voice link with a hearing party.

Abstract: A phase persistent agile signal source method, apparatus, and/or computer program product provides a direct digital synthesizer (DDS) clock rate, provides a frequency tuning word (FTW) for a desired output frequency, provides a DDS update for a desired DDS update rate, provides an equivalent frequency least significant bit (LSB) for the desired DDS update rate, provides a current phase of an LSB accumulator, and generates a coherent phase of the desired output frequency based on the DDS clock rate, FTW, DDS update rate to the DDS, equivalent LSB for the desired DDS update rate, and current phase of the LSB accumulator. The coherent phase can be the fraction portion of the result obtained from the multiplication of the FTW and the current phase of the LSB accumulator.
