  • Patent number: 6315203
    Abstract: A bar code reader includes a semiconductor laser diode as a source of an elliptical shape divergent laser beam and a shaping section for shaping the elliptical shape divergent laser beam to provide a shaped laser beam in the form of a circular shape collimating laser beam. A distance measuring section measures a distance to a bar code label and generates a distance information signal. A temperature sensor is attached to a casing of the shaping section. The temperature sensor detects the ambient temperature and generates a temperature information signal. A focal position controlling section conducts a focal position control in response to the distance information signal and the temperature information signal so that the shaped laser beam will have its focal position on the bar code label. A scanning section lights the bar code label with the shaped laser beam that has been subjected to the focal position control.

  • Patent number: 6202932
    Abstract: A method and module for transferring energy, clock frequency and data information without using an electrically conducting connection between a portable module and host equipment. Energy is transferred as optical radiation from at least two distinct light sources with intensities alternating between the minimum and maximum values in such a way that when one intensity goes from minimum to maximum the other goes from maximum to minimum wherein total intensity of optical radiation received by the module and supply voltage formed therefrom is nearly constant. The clock frequency is formed by and detected as the cyclical alteration of light intensities. Data is transferred as a modulation of the clock frequency.

  • Patent number: 6189795
    Abstract: A bar code reader having two reading windows, i.e., a bottom window and a side window. An increased number of scanning lines are used for constituting scanning patterns for scanning bar codes, and the arrangement of the optical system is contrived to decrease the whole size of the bar code reader and, particularly, to decrease the depth of the bar code reader. A source of laser light, a splitter for splitting the laser beam emitted from the laser light source into two, a reflection mirror for transmitting one beam from the splitter to a polygon mirror, the polygon mirror which rotates to scan the incident laser beam, a mirror system for emitting the beam reflected by the polygon mirror through the reading window, and a focusing member for focusing the beam reflected by the bar code onto a detector that detects the beam reflected by the bar code, are arranged on the same line in the bar code reader. By using a concave mirror, furthermore, the beam reflected by the bar code is folded back to one detector.

  • Patent number: 6184980
    Abstract: A silver halide fiber optic for the detection and identification of petroleum. The fiber optic serves both as a waveguide for transmitting a signal to and from petroleum in remote locations and also as an intrinsic part of the sensing element to obtain evanescent wave spectra. The evanescent wave is attenuated at various wavelengths based on the chemical composition of the petroleum in which the sensor is immersed. The spectrum obtained from an unknown sample is compared with the spectrum of known samples from a library to identify the unknown sample.

  • Patent number: 6173899
    Abstract: The present invention relates to methods and systems for power and energy transfer for non-contact IC cards, which is capable to communicate with an external device such as a host terminal. The disclosed method and system give the possibility to combine inductive coupling for remote power and data transmission, and capacitive coupling while IC card is attached to terminal, in order to transfer a large amount of energy. The new in the art is that bidirectional data and energy transfer from a terminal into an IC card is performing at two different carrier frequencies of an energy-transmitting alternating field. Herein the remote data transmission and energy transfer into the IC card is provided at first, lowest, frequency, utilizing the inductive coupling between a terminal transmitting-receiving coil and a IC card transmitting-receiving coil.

  • Patent number: 6168081
    Abstract: An invisible symbol reading apparatus includes a heating unit for heating an invisible symbol formed on a sample and containing a material which emits infrared light when heated, a detecting unit for detecting infrared light emitted from the invisible symbol, and an arithmetic operation unit for binarizing a detection signal from the detecting unit. The arithmetic operation unit calculates a differential coefficient of the detection signal, that corresponds to a position on the sample. On the basis of upper and lower threshold values set for the differential coefficient, the arithmetic operation unit determines a maximum value of the differential coefficient in a region exceeding the upper threshold value and a minimum value of the differential coefficient in a region smaller than the lower threshold value. The arithmetic operation unit binarizes the detection signal by using the maximum or minimum value as a leading or trailing edge of a binary function.

  • Patent number: 6158656
    Abstract: A method and apparatus for enabling a processor to execute processing routine even if a power-source voltage drop occurs during processing. When an ignition key switch 102 is closed, voltage VB is supplied from a vehicle-mounted battery B1 to a comparator AMP of a CPU 108 and to a power-source stabilizer circuit 201 of a regulator 200. Also, capacitors C1 and C2 are charged with a load from the vehicle-mounted battery B1. Even if the power-source line is momentarily interrupted while in this state, the capacitor C1 has already been charged, and so the transition of the drop in voltage VB is gradual compared with a case wherein the capacitor C1 is absent. Additionally, because the capacitor C2 has already been charged, voltage VCC supplied to the CPU 108 from the regulator 200 is held at a fixed value for a certain interval.

  • Patent number: 6154516
    Abstract: A cardiac gated spiral CT scanner (10) has a source of penetrating radiation (20) arranged for rotation about an examination region (14) having a central axis extending in a z direction. The source (20) emits a beam of radiation (22) that passes through the examination region (14) as the source (20) rotates. A patient support (30) holds a patient within the examination region (14) and translates the patient through the examination region (14) in the z direction while this source (20) is rotated such that the source (20) follows a helical path relative to the patient. A control processor (90) implements a patient-specific scan protocol in response to measured patient characteristics (for example, the patient's heart rate, the patient's breath hold time, and/or the range of coverage in the z direction based on the patient's anatomy) and scanner characteristics (for example, the number of detector rings, and/or the scan rate).
