Abstract: In one embodiment, the present invention is a method for reducing the peak-to-average power ratio (PAPR) of a multi-carrier modulated symbol, such as an orthogonal frequency division multiplexed (OFDM) symbol. The method first transforms a set of data symbols into a multi-carrier modulated symbol. The method then uses the multi-carrier modulated symbol and a gradient-descent algorithm to generate a set of symbols for PAPR-reduction tones. The data symbols and the PAPR-reduction symbols are then transformed to generate an updated multi-carrier modulated symbol. The PAPR-reduction symbols are iteratively updated until a terminating condition occurs (e.g., an acceptable PAPR is achieved for the multi-carrier modulated symbol).

Abstract: A pipe coupling for connecting a pipe to a flange associated with another pipe in a sealed manner. The pipe (10) is formed with circumferential groove (10a). The coupling comprises a gasket (20), a mounting ring (18), and a mounting flange (22). The ring (18) is elastically expandable, e.g. by being split, and formed with projecting rib (18a) adapted to fit into the groove (10a) and hold the ring affixed to the pipe (10). The mounting flange (22) is tightened against both the ring (18) and a counter-flange (12), through matching cone-shaped surfaces (18c, 22a).

Abstract: In one aspect, the present invention provides a ventilated seat with a valve sheet having one or more valve assemblies. The valve sheet maybe on a frame of the seat. The valve assemblies open in response to a force such as a force applied by an individual occupying the seat. In another aspect, the present invention provides a method of thermally regulating a seat by occupying a seat with a valve sheet. By occupying the seat one or more valves assemblies open air moving though the open valve assemblies thermally regulates the seat.

Abstract: A technique to provide an information-sharing system and the like is disclosed. According to this technique, there are provided an on-board information terminal to transmit one or more types of information among a vehicle information relating to user's own vehicle and on-board program information to acquire shared information, an area information acquiring system for acquiring area information, and an information-sharing server for calculating time function existing quantity based on time function according to one or more types of information among vehicle information and area information, calculates time function transmission quantity based on time function including the calculated time function existing quantity, arranges the calculated time function existing quantity and the time function transmission quantity to a corresponding position on a map, attaches the map information to the on-board program information, and transmits it to the on-board information terminal.

Abstract: In combination, a conventional cable tie and a cable encircling member having a width exceeding the width of the cable tie. The cable encircling member has an opening extending between upper and lower surfaces thereof. The free end of the cable tie tail is inserted from the upper surface of the cable engaging member through the opening and the tail of the cable tie is dressed along the lower surface of the cable engaging member such that the free end of the cable tie extends outwardly of an end of the cable encircling member. Conductors to be ensnared are now laid upon the upper surface of the cable encircling member. The free end of the cable tie tail is now inserted into the head of the cable tie forming the cable encircling member into a spiral coil loosely encircling the conductors. The free end of the cable tie is now pulled beyond the cable tie head until the spiral coil moves into tightly encircling relation with the conductors.

Abstract: A sprinkler assembly comprising in combination a sprinkler mounting stake and a sprinkler comprising. The sprinkler comprises a sprinkler body formed with a support member receptacle and locking portion. The sprinkler mounting stake comprises a ground insertion portion and a sprinkler support portion. The sprinkler support portion comprises a lateral support member extending parallel to a longitudinal axis of the stake and retention member. The support member is insertable within the support member receptacle and a retention member prevents unintentional disengagement of the sprinkler body from the mounting stake.

Abstract: A method for manufacturing a semiconductor integrated circuit device includes the steps of forming an isolation trench in an isolation region of a semiconductor substrate, filling the isolation trench up to predetermined middle position in its depth direction with a first insulating film deposited by a coating method, filling a remaining depth portion of the isolation trench into which the first insulating film is filled with a second insulating film, then forming a plurality of patterns on the semiconductor substrate, filling a trench forming between the plurality of patterns up to predetermined middle position in a trench depth direction with a third insulating film deposited by a coating method, and filling a remaining portion of the trench into which the third insulating film is filled with a fourth insulating film that is more difficult to etch than the third insulating film.

Abstract: A rotary sprinkler (10) including a water inlet, a water outlet arranged for rotation about a rotation axis (14), a water director associated with the water outlet and a watering pattern determiner associated with at least one of the water outlets and the water director. The sprinkler (10) operates to cause the sprinkler (10) to have a substantially non-repeated watering pattern extending over more than 360 degrees about the rotation axis. The watering pattern is asymmetric with respect to the rotation axis (14) and is rotated for each successive rotation of the water outlet about the rotation axis (14) with respect to the watering pattern of the preceding rotation by a predetermined amount, whereby the successive rotations increase the angular uniformity of watering about the rotation axis.

Abstract: A process for the treatment of water comprises: a) Adding to the water an oxidizing agent in a stunning concentration, wherein the detention time of said agent between adding it to water and the subsequent steps of filtration and/or irradiation is up to about 90 seconds; b) filtering the oxidized water by a filtration system having a filtering size larger than the average size of suspended organic matter in the water; and c) exposing the oxidized and filtered water to irradiation.

Abstract: A 3-way hydraulic valve comprising a body formed with an inlet port for connecting to a pressurized supply line, a first outlet port for connecting to an outlet line and being in flow communication with the inlet port, a gate intermediate the inlet port and the first outlet port, dividing the body into an inlet chamber and an outlet chamber, the body further comprises a second outlet extending from the outlet chamber, and a control chamber fitted with a deformable diaphragm sealingly engageable with the gate so as to prevent flow between the inlet port and the first outlet port, and a sealing port associated with the second outlet and comprising a sealing member linearly displaceable between a closed and an open position.
