Title: Orthogonal frequency division multiplexing based spread spectrum multiple access
Inventor: LAROIA RAJIV
IPC: H04W72/04
Filed: 2000-02-11
Granted: 2005-08-16
Abstract: In an orthogonal frequency division multiplexing (OFDM) based spread spectrum multiple access system the entire bandwidth is divided into orthogonal tones, and all of the orthogonal tones are reused in each cell. To reduce peak-to-average ratio at the mobile transmitter, each voice user is allocated preferably a single one, but no more than a very small number, of the orthogonal tones for use in communicating with the base station. Data users are similarly allocated tones for data communication, however, the number of tones assigned for each particular data user is a function of the data rate for that user. The tone assignment for a given user is not always the same within the available band, but instead the tones assigned to each user are hopped over time. More specifically, in the downlink, the tones assigned to each user are change relatively rapidly, e.g., from symbol to symbol, i.e., the user fast "hops" from one tone to another. However, in the uplink, preferably slow hopping is employed to allow efficient modulation of the uplink signal which necessitates the employing of additional techniques, such as interleaving, to compensate for the reduction in the intercell interference averaging effect. For data communication power control is employed in the uplink and/or downlink so that the transmission rate is increased, e.g., by increasing the number of symbols transmitted per tone per unit time or the coding rate, as a function of allocated power per tone and the corresponding channel attenuation.

Abstract: The apparatus for cooling a high power electrical transformer and electrical motors uses thermally conductive material (16) interleaved between the turn layers of a high power transformer and iron core laminates (12) to provide a low resistant thermal path to ambient. The strips (16) direct excess heat from within the interior to protrusions outsi de of the windings (14) and core where forced air or thermally conductive potting compound (22) extracts the heat. This technique provides for a significant reduction of weight and volume along with a substantial increase in the power density while operating at a modest elevated temperature above ambient.

Abstract: A method is described for writing real time video signals on an optical disc (2) having a recording area (40) which comprises an administrative area (43), a spare area (42), and a user area (41). Normal recording takes place in blocks (45) in a first pre-reserved area (NW) of a free part (47) of the user area (41). If during the recording process a defective block (45*) is encountered a replacement recording having the size of a plurality of blocks is made in a second pre-reserved area (RW) of the free part (47) of the user area (41), after which normal recording continues in the first pre-reserved area (NW). On the one hand, this limits the number of jumps for replacement recording and, on the other hand, it results in the storage capacity of the disc (2) being used very efficiently.

Abstract: The present invention is characterized in that the state of combustion oscillation in the combustor of a turbine of a plant such as a power plant is monitored from a remote monitoring center. To monitor combustion oscillation state, combustion oscillation data on the combustor is separated into two types of data; (1) the first data obtained on a real-time basis, and (2) the second data consisting of representative values within a predetermined period of time obtained from the first data. In the normal state, a low-speed communications mode is used to send the second data, which is monitored at the monitoring center. If an abnormal state is predicted as a result of monitoring the second data, the high-speed communications mode is used to send the first data, and more detailed combustion oscillation data is monitored at the monitoring center. When a critical state is predicted, an instruction is sent to the local site to switch the operation mode over to the low load operation mode, whenever required.
