Patent EP-0380441-A2 (EP)
Inventor: FAUSCH CHRISTIAN H
IPC: G01S15/10
Filed: 1990-01-09
Abstract: If in a transmitting and receiving range of an ultrasonic measuring device a second one is operating, this frequently leads to wrong switching operations. As previously, the loudspeaker/microphone unit (1) is connected to a transmitting/receiving circuit (2). The signal is allocated to a filter via an amplifier (3) and a subsequent limiter (4). This is a programmable band-pass filter (5) which operates at different frequencies both as oscillator for the transmitting signal by means of feedback and as band filter in the receiving position. A microprocessor (6) controls the various switches (S1-4) for operating the programmable band-pass filter (5). Various frequency sequences, which are changed in accordance with the result of the evaluation, can be called up from the program memory (10). This allows operation under the most difficult conditions, even in highly reflective rooms. <IMAGE>

Abstract: A thermal ink jet printhead is disclosed having an ink channel geometry that controls the location of the bubble (42) collapse on the heating elements. The ink channels (36) provide the flow path between the printhead ink reservoir (24) and the printhead nozzles (27). In one embodiment, the heating elements are located in a pit (37) a predetermined distance upstream from the nozzle (27). The channel portion upstream from the heating element has a length and a cross-sectional flow area that is adjusted relative to the channel portion downstream from the heating element, so that the upstream and downstream portions of channel have substantially equal ink flow impedances. This results in controlling the location of the bubble (42) collapse on the heating element to a location substantially in the center of the heating elements.

Abstract: The present invention is directed to ECL and NTL circuits with an ac-coupled complementary push-pull output stage which enables the circuits to operate at high speeds with minimum dc power dissipation and small switching current I CS . Similar to a conventional ECL circuit, the present ECL circuit has multiple input transistors (20, 21) which are differentially coupled to a reference transistor (22). The switching current I CS  is drawn from the common emitter (C) node and the signal at the common collector node (B) of the input transistors (20, 21) is applied to the base of an emitter follower transistor (24). The output (OUT) is taken from the emitter of the emitter follower transistor (24) which is connected to the common collector node (OUT) of a pair of complementary push-pull (PNP-NPN) transistors (25, 26). A biasing means (30, 31, 32, 33) is provided in order to bias the complementary transistors (25, 26) at cut-in ('NEARLY ON') condition and maintain a low stand-by current at the output stage. A pulse coupling means (34, 35), which is connected between the common emitter node (C) of the input transistors (20, 21) and the bases of the complementary transistors (25, 26), is used to apply a transient voltage pulse derived from a replica of an input signal to said bases to momentarily render one complementary transistor heavily conductive and turn the other one off. This will result in a large transient current flow in the conductive transistor thereby providing a fast pull-up or pull-down of the voltage at the output node.

Abstract: 2.1 In a baseband conversion of signals transmitted by means of a carrier frequency, frequency offset in the baseband signal may occur in the receiver due to tolerances and drift of the transmission frequency and the mixed frequencies, as a result of which transmission quality is impaired. In order to avoid or minimise impairment of transmission quality due to a frequency offset in the receiver, the frequency offset needs to be estimated continuously and to be compensated through automatic control. In strongly dispersive transmission channels, the results achieved using known frequency offset estimators are no longer satisfactory. 2.2 A device for frequency offset estimation which operates satisfactorily even in strongly dispersive transmission channels is obtained by feeding the signal converted into the baseband to a channel estimator, which forms a channel estimation vector H as an estimation of the instantaneous channel pulse responses in complex baseband representation, and by the frequency offset estimator evaluating the temporal variations in these channel estimation vectors. 2.3 The invention can be used, for example, in mobile radio receivers. <IMAGE>

Abstract: An improved error recovery system in which all operations which the Central Processor performs are categorized into one of a plurality of recovery types. The determination of category is made based on which architected and machine dependent facilities they manipulate and the manner in which the facilities are manipulated. This classification of instructions into types allows for the amount of checkpoint data to be minimized while allowing recovery to be generalized into broad algorithms instead of handling each operation independently. Furthermore, by applying this classification technique to various phases of execution (recovery windows) of instructions which modify system facilities before they complete, these instructions can also be retried with a minimum of hardware and algorithms.

Abstract: A frequency doubler (Fig. 7) or a frequency tripler (Fig. 4) is coupled to an amplifier (110) with a temperature compensation circuit (126) and a feed forward gain control loop (114,120,122,124,116). With such an arrangement, a frequency multiplier is provided wherein variations of an output signal of the frequency multiplier due to changing characteristics of the frequency multiplier caused by ambient temperature variation or from a varying input signal level are minimized. An anti-parallel pair of diodes (136a,136b) provides odd harmonics from an amplified (132) input RF signal. A high pass filter (138) selects the third harmonic and supplies it through an amplifier (112) and a coupler (114) to a variable attenuator (116). The coupler (114) supplies a signal to a detector (120) that drives one input of a differential amplifier (124). The temperature compensation circuit (126) supplies a reference signal to the other input of the differential amplifier (124). The output from the differential amplifier (124) is a control signal that controls the attenuator (116) to compensate for variations in the amplitude of the output from the high pass filter (138) and variation in the characteristics of the amplifiers (112,118) due to temperature change.

Abstract: A tile-oriented technique and associated apparatus for manipulating a continuous tone (contone) image through image rotation, anamorphic scaling and digital halftone screening for use in illustratively implementing a page description language. Specifically, an incoming contone image is first partitioned into aligned non-abutting tiles (e.g. 215 1 , 215 2 ,..., 215 9 ). Overlapping blocks (e.g. 217,, 217 2 , ..., 217 9 ) are then defined which will hold output data for corresponding tiles. To effect rotation and anamorphic scaling of the contone image, two-dimensional sampling increments, in fast and slow scan directions, are defined to relate movement between successive pixels in an output block to movement between corresponding pixels in the contone image. Similar, though independent, sampling increments, also in the fast and slow scan directions and based in part upon screen angle and screen ruling, are defined for movement between successive pixels in a halftone reference cell. To generate output data for each successive pixel location in a block, incremental sampling occurs in the contone image to yield a corresponding sampled contone value. This value, in conjunction with incremental halftone sampling addresses, then defines a sampling location that is read in a halftone reference plane (e.g. 242 181 ), the resulting output of which is single bit halftone data that defines a writing spot. Each tile in the contone image is successively processed, using two nested loops (1950, 1960), with resulting output data for that tile being written into appropriate pixel locations in a corresponding block in the output image. Clipping variables, incrementally varying in two-dimensional fashion and in unison with the contone pixel sampling location, define valid output data for a contone tile that is to be written into a corresponding block.
