Inventor: GOREN DAVID P
IPC: G06K7/14
Filed: 1990-08-24
Abstract: A method for reading bar code symbols which enables legitimate characters recognized by the code in use to be derived from a plurality of scans corresponding to illegitimate characters not recognized by the code in use is disclosed. The method includes the steps of storing representations of the bar code symbol which cannot be decoded to produce legitimate character(s). One of the representations is improved, or corrected, using another representation, and an attempt is made at decoding the corrected representation to produce a legitimate character. If the decoding attempt is not successful, further corrections are made in order to provide a representation which may be decoded to produce a legitimate character.

Abstract: Methods and apparatus are described for processing branch instructions using a history based branch prediction mechanism (such as a branch history table) in combination with a data dependent branch table (DDBT), where the branch instructions can vary in both outcome and test operand location. The novel methods and apparatus are sensitive to branch mispredictions and to operand addresses used by the DDBT, to identify irrelevant DDBT entries. 
     Irrelevant DDBT entries are identified within the prediction mechanism using state bits which, when set, indicate that: (1) a given entry in the prediction mechanism was updated by the DDBT and (2) subsequent to such update a misprediction occurred making further DDBT updates irrelevant. Once a DDBT entry is de­termined to be irrelevant, it is prevented from updating the prediction mechanism. 
     The invention also provides methods and apparatus for locating and removing irrelevant entries from the DDBT. The update packet, sent by the DDBT to the history based prediction mechanism, is expanded to include the test operand address actually used by the DDBT. If the state bits indicate the update is irrelevant, then the operand address can be used to locate and delete the offending DDBT entry since the DDBT is organized based on operand addresses. Additionally, the invention provides for inhibiting creation of further DDBT entries when a Branch Wrong Guess event occurs subsequent to a DDBT update to a given prediction mechanism entry.

Abstract: A method for regulating the power of a pump driven by a variable-speed electric motor is specified, by means of which a fluid is moved along prescribed paths in a system. In order to calibrate the system, which is designed, for example, as a heating installation, the electrical signal of a probe is recorded, at least in stages, for an arbitrary state of the system, at a plurality of points in conjunction with pin-point setting of the pump power and associated percentage flow velocity of the fluid from shutdown of the pump up to 100% power thereof corresponding to 100% flow velocity, and fed to a computer as measured value, in each case. The computer generates a characteristic which runs through all the measured values supplied by the probe. The pump is then regulated by the computer in accordance with the characteristic. The characteristic is then automatically adjusted by the computer in each case when a higher flow velocity of the fluid occurs owing to changes in the system.

Abstract: 2.1 Directional characteristics of transducer arrangements having a multiplicity of transducer elements, which are arranged at equidistant intervals greater than half the wavelength, have so-called grating lobes of equal sensitivity in addition to the main lobe. If the transducer elements are distributed randomly, the grating lobes are attenuated such that incorrect bearings are prevented. However, to generate a plurality of directional characteristics or a directional characteristic which can be pivoted, individual propagation time compensation or phase compensation must be provided for each direction and each transducer element. 2.2 In order to simplify the circuit complexity for directivity formation, the multiplicity of transducer elements is split, according to the invention, into groups, the transducer elements within the group being arranged at the same intervals and being arranged from group to group at 1.5 times the value of the interval. The groups have identical or different numbers of transducers which reduce from the centre outwards, as a result of which the received energy from the grating lobe direction is greatly attenuated. 2.3 The transducer arrangement can be used advantageously in underwater sound technology for broadband or narrowband passive or active systems, especially for reception. <IMAGE>

Abstract: Before printing operation, the print head is driven to the platen (17) to press the print form (18) against the platen and then retracted through a predetermined distance to provide a predetermined amount of gap between the print form and print head regardless the thickness of the print form. A planetary gear (4) is provided to engage with a drive gear (3) supported on the drive motor shaft (1) and is biased by a spring (12) to operatively engage with a sun gear (5) which is engaged with a rotary shaft (15) linked to the head carriage through a cam mechanism (9a,9b), so that the drive power of the motor can be delivered to the rotary shaft through the drive gear, planetary gear and sun gear. When the print head presses the print form against the platen, the reaction of the planetary gear from the sun gear is increased to move the planetary gear around the sun gear against the spring, so that the drive power can be no longer delivered to the sun gear to result in the rotation of the rotary gear being stopped. In response to sensing the stop of the rotary shaft, a control circuit (22) provides a control signal to the motor for reversely rotating it by a predetermined amount to make the planetary gear deliver the reverse rotation to the rotary shaft through the sun gear, so that the print head is driven to move away from the platen to provide a predetermined amount of gap.

Abstract: A light or infrared electrical signals transmission system without waveguides, in particular for sound broadcasts, digital signals, measured values or moving television pictures, enables the simultaneous, bidirectional transmission of the signals between two system devices of an identical type. A plurality of systems of this type can be operated simultaneously alongside one another. The optical radiation is propagated between the two devices either directly or through reflection, diffusion or diffraction. Circuitry costs can be kept particularly low through suitable selection of the transmission parameters, since for each device only one frequency-defining oscillator is required for both transmission and reception.

Abstract: The invention relates to a process and an arrangement for central monitoring of the operation of lamps which are connected in parallel via power supply lines, each lamp being allocated an interrogation circuit, to confirm the lamp operation, and a coded address, and a central monitoring unit using the addresses to initiate an interrogation of the lamp operation. In order to achieve a minimum installation cost and to prevent the possibility of connection errors, it is proposed with the invention to supply a high-frequency carrier signal in the supply line in order to interrogate the lamp status, which carrier signal is used to transmit the addresses by modulation using audio-frequency pulses. The report on the lamp status preferably takes place by means of a current load on the carrier frequency transmitter. An arrangement is additionally proposed, in which the monitoring devices (18) on the lamp side are installed together with an electronic ballast unit (19) in the screw or plug base of a fluorescent lamp (20). <IMAGE>

Abstract: An apparatus and a method for integrating several petroleum refining processes so as to efficiently produce tertiary alkyl ether compounds from a feed stream containing both saturated and unsaturated hydrocarbons is disclosed. An important step for forming isoolefins in the integrated process involves simultaneous catalytic conversion of an isoparaffin to an isoolefin and an n-olefin to an n-paraffin in a combination hydrogenation/dehydrogenation reactor. The thus produced isoolefin is reacted with a primary alcohol to form the desired tertiary alkyl ether compound in an ether forming process. Other conversion process included in the overall integration are an isomerization process to convert n-paraffins to isoparaffins and optionally an alkylation process to convert isoparaffins and olefins to an alkylate product.
