The inks include one or more populations of fluorescent quantum dots dispersed in polymeric material, having fluorescence emissions between about 450 nm and about 2500 nm; and a liquid or solid vehicle. The vehicle is present in a ratio to achieve an ink viscosity, surface tension effective, drying time and other printing parameters used for printing processes.

Abstract: Methods and apparatuses presented herein control antenna connectivity for a wireless communication device as a function of rotation of a connector assembly plugged into the device, such as where an external antenna or cable includes the connector assembly. Assuming the device has a mating connector for the external antenna that changes the connections of internal and external antennas as a function of the connector mating depth, the method comprises configuring the wireless communication device and/or the external antenna with a mechanical feature that changes the mating depth between the device's and the antenna's mating connectors responsive to external antenna rotation. In one embodiment, a body portion of the external antenna retains the mating connector and includes a cam feature or other mechanical feature that engages an edge or surface of the device as the antenna is rotated, thereby pushing the antenna out from the device.

Abstract: The present invention uses metallization termination techniques to reduce the electro-magnetic field scattering at the edges of metallized areas. The metallization termination techniques provide a gradual transition from high conductivity areas to high impedance areas. The mobile phone antenna illuminates the PCB allowing currents to flow on the PCB. When the currents reach edges of the PCB they flow through a region of increasingly high impedance without reflecting back or scattering.

Abstract: A mobile terminal having a two part housing enabling a first part of the housing to slide laterally and longitudinally and to pivot relative to the second part of the housing. This enables the terminal to assume at least eight configurations. With such variety of configurations, the housing may change function with a change in configuration. This enables the user to use the terminal for a number of different functions by repositioning the device to a different configuration. A first position, for example, may be for PDA use with an alphanumeric keypad exposed. Another position may be for cellular telephone use with a numeric keypad exposed. Another position may be for use as a digital camera, and another use may be that of a global positioning device. A further use may be that of a video conferencing device. Yet another device may be that of a gaming device.

Abstract: A system and method for distinguishing a first light source from other light sources utilizes an image receiver that can selectively engage and disengage a filter. The filter can be configured to either block bands of light corresponding to the light being emitted by either the first source or the other sources. By sequentially engaging and disengaging the filter from the image receiver, the first light source may be distinguished from other light sources.

Abstract: A wireless adapter enables a camera or other digital camera without inherent networking capability to post or send images to a remote destination. The wireless adaptor comprises a wireless interface for communicating with a remote destination over a wireless network, a camera interface to interface the wireless adaptor to a camera, and a file transfer agent. The file transfer agent uses the wireless interface to transfer the image data received from the digital camera to a destination device. In at least one embodiment, the file transfer agent emulates one or more printers, with each emulated printer corresponding to a different destination. With that configuration, the wireless adaptor transfers image data received from the digital camera to a selected destination based on which emulated printer is selected by the digital camera. Destination parameters for multiple destinations can be loaded and stored in the wireless adaptor.

Abstract: The present invention selectively uses a high-impedance layer to reduce the effects of E-M scattering at metallic discontinuities. The high-impedance layer can be fabricated using a combination of metallic and resistive materials that are typically used in electro-static discharging (ESD) applications. A thin layer of metal can be deposited on the surface of a dielectric substrate such as polyethylene. This metallic layer can be on an inner, outer, or buried layer of the material. The metallic layer allows the RF induced currents to spread out over a designated surface area. A layer of resistive material can be applied to a similar dielectric layer. The resistive layer provides sufficient attenuation to decrease the RF surface waves and minimize electro-magnetic scattering on the printed circuit board (PCB). Furthermore, since the metallic and resistive materials can be applied in very thin layers, sufficient transparency can be preserved in desired areas such as the mobile phone's display region.

Abstract: An antenna configuration for a flip type mobile phone is disclosed. The antenna configuration is designed to reduce, to a hearing aid compatibility (HAC) M3 rating or better, any scattered EM field effects that can cause interference to an active hearing aid. The antenna configuration comprises a halfwave type antenna extendable from the lower portion of the mobile phone. The antenna does not share the same vertical axis as the lower portion of the mobile phone when extended. Rather, it forms a tilt angle (?) that extends the antenna away from the upper portion of the mobile phone creating a greater separation distance between the speaker and the antenna. An antenna feed contact couples the antenna to components within the mobile phone. An antenna matching network can tune and attenuate the antenna configuration to enhance operation in the GSM frequency bands.

The supplemental antenna assembly includes a parasitic element supported by a frame. The frame is configured to be attached to the housing of the portable device such that an inductive coupling is provided between the parasitic element and the integral radio antenna. The parasitic element may include, for example, an antenna and/or a coupling element, e.g., a coupling element configured to be connected to an external antenna.

Abstract: A security locker 10 holds an open drink 14 so that it cannot readily be tampered with, and is such that an inebriated person can (1) readily open the locker door 12 by a single action, e.g. by the insertion of a credit card 16 or other flat or card-like key 16, (2) can readily insert and/or remove the drink 14 due to the locker shape, e.g. to guide a hand reaching into the locker 10 to facilitate retrieving the drink 14 and make spillage less likely, and (3) is less likely to be wounded stumbling against the locker 10, e.g., since said door 12 is adapted not to open outwards but to move around the inside of the locker periphery, rotating about a pivot 38, and the locker 10 has a suitable external shape, convex facing the front. After inserting said drink 14, closing and relocking the door 12, the key 16 is retained and a token 20 issued, required to be re-inserted to remove said drink 14.
