Abstract: A wireless network may have a digital base station and a radio link converter unit. The digital base station may receive bearer data for each of a plurality of channels, establish control information for each of the plurality of channels, and output a digital signal that defines the bearer data and the control information. The radio link converter may receive the digital signal and extract from the control information, for instance, a power level for each of the plurality of channels and a modulation frequency. Based on the power level and the modulation frequency, the radio link converter may responsively generate an analog signal having a plurality of analog channels that defines the bearer data in the digital signal. The radio link converter may then output the analog signal to an antenna for transmission to a wireless terminal.

Abstract: The present invention relates to a secondary lid for use with a package containing a foodstuff. That package has an opening that is initially sealed at purchase but the opening is unsealed by the consumer in order to obtain access to the contents of the package. There is a secondary lid that is affixed to the package and which reseals the opening and protects the contents from the external environment. The secondary lid may contact a flap or flaps of the package to hold the flap or flaps tightly closed to the opening or, in the case of a liquid, there may be a plug that enters the opening to prevent the contents from spilling. In any case, there is a seal formed in the secondary lid that surrounds and seals the opening from the environment to protect against the intrusion of air or moisture or other contaminants.

Abstract: An apparatus and method are shown for receiving multi-path signals. A rake receiver is used to receive multi-path signals. The rake receiver contains multiple fingers that act as correlators, where each finger is synchronized to one of the multi-path signals. Each finger of the rake receiver includes a variable delay element. The delay of the variable delay element in each finger may be determined by calculating the amount of time for a signal to travel from an antenna to the receiver, due to the path traveled, and setting the delay based on the measured travel time. The delay of the variable delay element in each finger may also be determined by scanning through a range of delays of the variable delay element and measuring an output signal level of the finger, the variable delay element then being set to the delay corresponding to the highest measured output signal level.

Abstract: A method and system for optimizing the use of antennae in a CDMA distributed antenna system. A pathway manager may identify and select an optimal antenna to transmit a wireless signal from a BTS to a receiver. The non-selected antennae may be disabled from transmitting signals to the receiver by suppressing the Walsh code and PN offsets of the BTS and receiver. The pathway manager may use criteria such as availability, proximity, reliability, and strength of signals and antennae to select an optimal antenna. Communications between the receiver and the antennae may be used to determine such criteria. By selecting an optimal antenna, the pathway manager may conserve energy from a BTS and reduce power requirements for an antenna system.

Abstract: The present invention pertains to the selection of cathode materials. The cathode materials of concern are the conducting polymer or backbone and the redox active species or sulfur species. The selection of the materials is based on the characteristics of the materials relating to the other components of the batteries and to each other. The present invention also pertains to the resultant cathode materials, particularly a selected cathode material of a single component sulfur-based conducting polymer with the sulfur species covalently linked to the conducting polymer, and most particularly a thiophene based polymer with covalently linked sulfur species. The conducting polymers have been covalently-derivatized with sulfides and/or sulfide-containing groups as battery cathode materials. The present invention also pertains to a battery employing the selection method and resultant cathode materials.

Abstract: Methods and apparatus employ the use of arrays (301, 902) of two or more electronically-discrete electrodes (1, 2, 3 . . . ) to facilitate high-throughput preparation and testing of materials comprising two or more elements. High rates of deposition, synthesis and/or analysis of materials are achieved with the use of arrays of electrodes whereby desired materials are developed. The high rate synthesis and/or analysis of an array of materials uses deposition control techniques in conjunction with the electrode array to develop a meaningful array of materials and to analyze the materials for desired characteristics to develop one or more materials with desired characteristics. The use of an array of electrodes enables high-throughput development of materials having scientific and economic advantages.

Abstract: One embodiment of this method involves using an acoustic device (including devices that emit acoustic waves at subsonic, sonic, and ultrasonic frequencies) that induces pressure changes at high frequencies. Those pressure changes could be induced across a large area from a single device location. Thus, one acoustic device located in one wellbore can desorb gas from a large volume of coal.

Abstract: A receiver sheet for thermal transfer printing comprises a sheet-like substrate supporting a backcoat comprising a cross-linked organic polymer which is a reaction product of a polyalkylene glycol and a polyfunctional organic cross-linking agent reactive with the terminal hydroxyl groups of the polyalkylene glycol. This provides a surface which may be written on using aqueous inks, and to which water-activated adhesives may adhere. Suitable cross-linking agents are hexamethoxymethylmelamines or oligomers thereof. The backcoat is free from alkali metal salts to avoid retransfer problems, and may also be textured by particulate material embedded in the cross-linked polymer, to improve handling properties.

Abstract: A receiver sheet for thermal transfer printing comprises a substrate having a dye-receiving side and a backcoat on the other side, characterised in that the major component of the backcoat is a partially esterified styrene/maleic anhydride copolymer. This provides a surface which can readily be written on using aqueous inks or ball pens, and can be adhered to by water-activated adhesives. It is also resistant to retransfer of dye from an underlying print, e.g. during storage. The backcoat may also contain antistatic agents and fine inert particles to improve handling properties, appearance and tooth.
