Abstract: Methods, systems, and devices for wireless communications are described to enable base station and a user equipment (UE) to mitigate interference when using full-duplex communications. For example, a method for wireless communication comprises: receiving an indication that a transmission time interval, TTI, for an uplink transmission is full-duplex; identifying a cyclic prefix length for the uplink transmission, wherein the cyclic prefix length is based at least in part on the TTI being full-duplex and is longer than at least one cyclic prefix length available for half-duplex TTIs; and transmitting the uplink transmission based at least in part on the cyclic prefix length.

Abstract: A device for spreading of radar chaff from airplanes is described. The device comprises a magazine (29) for said chaff which by means of a motor-operated displacement member may be displaced towards an ejection opening (30). The device comprises a cover (21) having attachment means (22) by which the cover may be applied on the airplane in an existent beam position for hanging of weapons or other equipment. The cover is also provided with attachment means (24) and in connection to said attachment means coupling members (23) and contact members (27), respectively, are provided, said contact members being connected to some of said coupling members via transfer means (28). The device may be used for a mechanical, electrical or a different adaption between the airplane and equipment or weapons which may be carried by the same and may for example have the shape of a missile launch for firing of hunting missiles. Thereby is obtained the advantage that it is not necessary to use a beam position for carrying a unit for spreading of chaff only. As a consequence an airplane may carry a number of symmetrically suspended spreading devices according to the invention, and thereby a high chaff spreading capacity and an effective use of the chaff may be obtained without influencing notably the weapon carrying ability, weight or aerodynamic features of the airplane. If desireable an airplane may always carry one or more spreading devices according to the invention. (Fig. 2).

Abstract: This specification discloses a method for generating an engine energy output signal for use by an adaptive strategy in controlling the performance of a spark ignited automobile combustion engine. An estimated future energy output combines the weighted sum of a short term energy output average, a medium term energy output average and a long term energy output average. The adaptive strategy adjusts spark timing and distance of EGR as a function of engine energy usage per distance traveled while maintaining feedgas emissions at a constant level over a wide variety of driving patterns including urban, suburban and highway. This adaptive strategy has advantageous fuel consumption characteristics which are greatest at the most constrained feedgas levels. Drivability can be enhanced because of the greater calibration flexibility inherent to the adaptive technique.

Abstract: A process for the removal of sulfur oxides from two gas streams containing the same. One gas stream is introduced into a spray dryer zone and contacted with a finely dispersed spray of an aqueous medium containing an absorbent for sulfur oxides. The aqueous medium is introduced at a controlled rate so as to provide water to the gas in an amount to produce a cooled product gas having a temperature at least 7°C. above its adiabatic saturation temperature and from about 125.300% of the stoichiometric amount of absorbent required to react with the sulfur oxides to be removed from the gas stream. The effluent from the spray dryer zone comprises a gas stream of reduced sulfur oxide content and contains entrained dry particulate reaction products including unreacted absorbent. This gas stream is then introduced into a particulate removal zone from which is withdrawn a gas stream substantially free of particles and having a reduced sulfur oxide content. The dry particulate reaction products are collected and utilized as a source of absorbent for a second aqueous scrubbing medium. Concurrently, the other gas stream is introduced into an aqueous scrubbing zone and contacted with the second aqueous scrubbing medium containing unreacted absorbent for the sulfur oxides. An effluent gas stream is withdrawn from the aqueous scrubbing zone and comprises a water-saturated gas stream of reduced sulfur oxide content and substantially free of particles. The effluent gas streams from the particulate removal zone and the aqueous scrubbing zone are :ombined in such proportions that the combined gas stream has a temperature above its adiabatic saturation temperature.

Abstract: The dust collector is for removing dust from a gas. The contaminated gas is drawn into a filter chamber (8) where it passes through hollow, flat, box-like, cloth covered filter members (7) and into gas passages (9'). Dust is separated from the gas by the filter members and at least some of this dust builds up on the outer surfaces of the filter members thereby gradually reducing their efficiency. To dislodge this built up dust compressed air is introduced into the filter members through outlets (11) thereof from compressed air outlets (12) disposed in the gas passages. In order to make this possible with a small capacity compressor, an outlet (14) in the gas passage is closed and an atmospheric air inlet (15) in the gas passage is opened by a piston and cylinder unit (16, 17) which operates respective valves (18, 19) when the compressed air is introduced into associated filter members. Only those filter members associated with one of the gas passages are cleaned at a time so that the collector can continue with its dust removal operation during this cleaning process.

IPC: H01L21/467
Filed: 1983-09-01
Abstract: A procedure is described for producing semiconductor devices having damage-free surfaces in electrochemically n-type and intrinsic compound semiconductors. The process involves a photoetching procedure including applying a potential to the compound semiconductor while it is in contact with an electrolytic solution and irradiating the surface to be etched with light in a certain energy range. By suitable adjustment in the potential, electrolytic solution composition and light energy, the etch rate is made proportional to the light intensity. By suitable variation in light intensity and light-ray direction, various geometrical features can be made on the surface of the compound semiconductor. For example, a hole with straight sides can be made in the compound semiconductor by use of a light spot and parallel (collimated) light rays. An advantageous application of this process is the fabrication of a photodiode with a hole in the center for use in bidirectional communication systems and to monitor power output for optical communication sources. The advantage of this process is that no damage occurs outside etched hole so that a maximum area of the photodiode remains active for detecting incoming radiation. Another advantage of the process is that etching will stop where the material becomes p-type so that etching can be made to stop automatically at a p/n junction.
