Abstract: A data carrying medium comprises a fluorescent layer with data carrying structures. The fluorescent layer includes fluorescent dye molecules embedde d in a polymer base material. By employing a laser beam in order to create the  data carrying structures, these obtain a lower fluorescence in relation to t he fluorescence from a corresponding region of the virgin, fluorescent layer wh en the data carrying structure is irradiated with fluorescence exciting radiation. By modulating the laser beam several bits can be stored in each data carrying structure, with the result that the value of a stored datum corresponds to the value of a specific level in a multilevel code. The store d data are read by means of fluorecence excitation of the fluorescent dye molecules in the data carrying structure. The fluorescence is detected in a detector device, the intensity of the detected fluorescence corresponding to  the value of the stored datum. In this fashion 1-10 bits can be stored in a data carrying structure smaller than 0.25 .mu.m2. This is a substantial increase in the data density compared to previously known optical data stora ge media.

Abstract: A distributed communications switching system and its associated telecommunications network infrastructure(10) includes a plurality of interconnected switching systems (12 1, 12 2 and 12 3), some of which may be controlled by another switching system and its associated telecommunications network infrastructure. The switching systems are controlled via at least one switch processing platform (16) that generates generic commands for receipt by the switching systems in response to signaling messages received by the SPP. A fabric application interface (19) couples the switching systems to the switch processing platform for distributing generic commands to and from the appropriate switching system and for translating the generic commands into native commands (or vice versa) for execution by the switching system. The fabric application interface also translates signals received at the switching system into generic commands for receipt by the switch processing platform. The ability of the fabric application interface to distribute generic commands to and from the switching systems and to communicate signals received at the switching systems allows the switch processing platform to exercise call control for each switching system regardless of the nature of the call processed thereby, allowing greater flexibility and cost-effective use of application software (both service control and basic call control), and other associated telecommunications network infrastructure such as service circuit equipment.

Granted: 2002-05-14
Abstract: A beacon signal (313) is provided in a wireless communication system using a hybrid matrix (303) and an inverse hybrid matrix (306). Using an unused port of the hybrid matrix (303), the beacon signal (313) is combined with traffic signals (316) intended for users of the wireless communication system. The hybrid matrix (303) transforms beacon signal (313) and the traffic signals (316) into output signals that each contain a portion of the beacon signal (313) and the traffic signals (316). The outputs from the hybrid matrix (303) are amplified by amplifiers (315). The outputs from the amplifiers (315) are then inverse transformed by an inverse hybrid matrix (306). The inverse transform matrix (306) recombines the portions of the beacon signal (313) and the traffic signals (316) originally input to the hybrid matrix (303), and the resulting signals are transmitted using sector antennas (320) and a beacon antenna (323).

Abstract: This is a process, with the entailing equipment arrangement and machinery, designed to produce charcoal and graphite of selectable varying degrees of volatile content from all types of waste wood, bark, and vegetable matter. The procedures used in the past, or those current or planned for the future are obsolete, time consuming, inefficient, and dangerous, and require vast amounts of investment capital to bring into production. The process I have outline is continuous, 24 hrs. per day seven days a week, safe, non-pollutant, profitable, and requires the minimum capital expenditure necessary to produce a commodity of the highest quality. Instead of the huge vertical, gravity feed retorts, and the attendant costs and dangers they generate, this process is not reliant on gravity in vertical retorts but uses horizontal force fed, oxygen negligent tubes arranged in tiers of rows across the width of the refractoried oven, each tube independently controlled, vented, and monitored and small enough to prohibit massive volumes of exhaust gases at extreme temperatures thus eliminating dangerous conditions. With the requirement of only two people per shift to operate it, the machine is extremely cost efficient. Because it can use any and all wood waste, mixed up with bark in any ratio it is also a complete solution to the forest industry waste proliferation problem in any region with forest based industries. It can use the waste from the harvesting in the bush, to the manufacturing of finished products. It can use various other types of vegetable waste with minor modifications to the raw material handling procedures.

Title: Ac transmission system with reactance compensation
Inventor: TANAKA SHIGERU
IPC: H02J3/18
Filed: 1999-04-09
Granted: 2001-10-02
Abstract: A series compensation generator SCG is installed in a transmission line that links various substations SS and the transmission capability of the system as a whole can be increased by regulating the equivalent reactance of the transmission line. Series compensation generator SCG generates a voltage of which the phase angle is shifted substantially 90° in relation to the current flowing in the transmission line, and it also generates a voltage that compensates the voltage drop due to the equivalent reactance.      Also, when an electrical fluctuation phenomenon (power oscillation) occurs in the transmission line, it is possible speedily to suppress the power oscillation by detecting the power fluctuation of the transmission line and controlling the compensating voltage of series compensation generator SCG so that it suppresses that power fluctuation.
