Title: Fuel combustion system, method, and nozzle member therefor
Inventor: GRAZE RUSSELL R JR
IPC: F02B19/12
Filed: 1990-12-03
Abstract: This invention relates to a fuel combustion system (10) for a lean burn internal combustion engine (12). Because of the lean fuel/air ratio, it is difficult to consistently achieve complete and thorough combustion within the main combustion chamber (28) because of the relatively slow rate of flame propagation. The subject fuel combustion system (10) includes a precombustion chamber assembly (37) defining a prechamber (52) having a preselected shape and volume and includes a plurality of ejection passages (132). The passages (132) are of a preselected geometric cross-section for directing and controllably expanding burning gases from the prechamber (52) into the main combustion chamber (28) at a velocity greater than the speed of sound in order to penetrate and cause igniting and burning in the main combustion chamber (28) for faster and more complete combustion.

Title: Double reflector
Inventor: HUGENELL HERMANN
IPC: G02B27/58
Filed: 1991-12-10
Abstract: Abstract of the Disclosure A double reflector is described which comprises two spaced apart primary mirrors oriented toward a common focus. The optical system further comprises two separate secondary de-flector mirrors as well as tertiary deflector mirrors for beam concentration on a common focus. Both the primary mirrors and the secondary deflector mirrors are so-called off-axis reflec-tors, i.e. their surface represent surface sectors of a hypo-thetical big aspherical mirror body each. As surface sectors of a hypothetical big hyperbolic mirror, the primary mirrors are inclined at an angle with respect to the common optical axis and each disposed at a given spacing from the same in such manner that the inner marginal rays of the incident ra-diation which are closest to the optical axis, will converge. As of a diameter of > 8 m, the primary mirrors are to be com-posed of individual segments, each be coupled (sic, the trans-lator) with the respective associated segments of the second-ary deflector mirror, which are located opposite them in the beam path, by way of a high-precision computer assisted measuring system such that each deviation of the primary mirror segments in their bearing position is enabled by a cor-rective movement of the respective opposite segments of the secondary deflector mirror, carried out in real time by way of actuators.

Title: Method and apparatus for transforming low bandwith telecommunications channels into a high bandwidth telecommunication channel
Inventor: MANN ALAN B
IPC: H04J3/00
Filed: 1992-09-01
Abstract: Abstract of the Disclosure Low bandwidth telecommunications channels are transformed into  a  high  bandwidth  telecommunications  channel  by determining  the  relative  transmission  delays  among  a plurality of relatively low bandwidth channels which are to be combined into a relatively high bandwidth communications channel. The transmission time delay across the plurality of low bandwidth channels is then equalized so that the time delay   equalized   low   bandwidth   channels   combine   to effectively form  a  single  high  bandwidth  channel.   The relative transmission time delays among the low bandwidth channels may be  determined by  transmitting  an  alignment (synchronization)  signal across each of the low bandwidth channels,  receiving the alignment signal from each of the low bandwidth channels, and measuring the time differences among the received alignment signals at each of the low bandwidth channels.  Based on the measured time differences, time delay across the plurality of low bandwidth channels is equalized, so that the transmission time delay equalized low bandwidth channels may be combined to effectively form a single high bandwidth channel.

Filed: 1993-01-21
Abstract: A sensor grid system  (10),  and a method of operating a sensor grid system, having a first array of inductors (14a) and a second array of inductors (14b). The first and the second arrays are each responsive to a moveable coil (18) that  transmits  an  electromagnetic  signal  for  having  a detectable signal  induced therein.  The method includes a first step of determining an expected position of the coil relative to an array of inductors. A next step selects a pair of inductors that are located near to the expected position. A third step measures the signals induced into the pair  of  inductors,  and  a  fourth  step,  based  on  the measurement step, determines any additional inductors from which measurements are required to interpolate the actual position of the coil.  A fifth step measures the signals induced  into  the  determined  ones  of  the  additional inductors, and a sixth step computes and reports the actual position of the coil based on the results of the first and the second steps of measuring.  Significantly,  the pair of inductors and the additional inductors include all inductors that are required to compute the  actual position of the coil,  and includes no inductors that are not required to compute the actual position of the coil.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for approximating the doppler frequency of a mobile station (M1-M9) by examining the signal between the mobile station (M1-M9) and a base station (B1-B10).  Several channel estimates (hj(n)) are calculated at different intervals (t1, t2) for the signal between the mobile station (M1-M9) and the base station (B1-B10).  The difference (Vj(n)) between these channels estimates (hj(n)) is used to determine the approximate doppler frequency of the mobile station (M1-M9).  A cellular mobile radio system can use the doppler frequency of the mobile station (M1-M9) to prioritize a handoff queue or to select an appropriate detecting algorithm for detecting data in a received signal (r(t)).
