  • Auto ranging counter
    Patent number: 4546487
    Abstract: At the inception of a time interval whose duration is to be measured, pulses whose rate may be varied are applied to a first counter. A second counter controls the rate of the pulses applied to the first counter. An overflow sensing circuit is connected to the output of the first counter for, in response to each overflow signal at the output of the first counter, incrementing the second counter which then causes pulses having a new rate to be applied to the first counter and for, concurrently, presetting the counter to a new count. The new rate is equal to 1/N the old rate and the new count is equal to 1/N the count in the first control prior to the overflow. The elapsed time information in the circuit is therefore always valid.

  • Solid-state color-encoding television camera
    Patent number: 4546380
    Abstract: An image of periodic color-filter stripes derived by a periodic lenticular array is made to coincide with a periodic pattern of discrete solid-state light cells of an imager, despite manufacturing tolerance errors in the values of the respective periods of the filter and array with respect to the value of the period of the imager. This is accomplished by angularly displacing each of the respective axes of the periods of the filter and imager, with respect to the axis of the period of the array, by a calculable amount.

  • Reducing noise in introducing bias charge into charge transfer devices
    Patent number: 4541068
    Abstract: A bias charge (commonly known as a "fat zero") is divided into a plurality, n, of equal parts. These equal parts are differentially delayed, and the results appearing parallel in time are summed to generate a bias charge with reduced noise. The reduced-noise bias charge is then applied to an input of a charge transfer device -- e.g., one of the charge coupled device (CCD) analog shift registers used in a CCD imager to transport charge packets descriptive of picture elements in an imager.

  • Standardized multi-stack dielectric-layer filter blank and method for fabricating color-encoding filter therefrom
    Patent number: 4534620
    Abstract: A green-manifesting blank comprised of yellow and cyan dielectric stacks, one on top of the other, supported by a transparent substrate can be used to fabricate a green, yellow or cyan, and white color-encoding filter having any arbitrary given spatial pattern by combining dry-etching and wet etching, if the top layer of the bottom stack is composed of a material which is inert to a given wet etchant and the bottom layer of the top stack is composed of a material which is etched by the given wet etchant. Alternatively, the wet etching can be dispensed with if, after completion of the color-encoding filter, the filter is covered with an overcoat material exhibiting an index-of-refraction substantially equal to that of the bottom layer of the top stack.

  • Detection circuitry with multiple overlapping thresholds
    Patent number: 4529892
    Abstract: Circuitry for discriminating between input signals having peak amplitudes which fall with two ranges includes two Schmitt triggers having their input terminals connected to a common circuit input terminal. The trigger points of the two Schmitt triggers overlap each other. The potential difference between the upper trigger points of the two Schmitt triggers establishes one of the input signal amplitude ranges. Signals with amplitudes greater than the upper trigger point of the higher of the two upper trigger points fall into the second of the two signal ranges. Decoder circuitry coupled to the outputs of the two Schmitt triggers determine if one or both of the Schmitt triggers is regularly responding to the input signal and thereby the relative amplitude range of the applied signal.

  • Suppression of edge effects arising in CCD imager field registers
    Patent number: 4528596
    Abstract: If drain structures bound the field register(s) of a CCD imager on the sides parallel to the direction of charge transfer therethrough, some portion of the charge carriers generated by photoemission will be lost to the drain structures from the charge transfer channels along those sides. If the charge transfer channels along those sides of the field register(s) do not have register boundary drain structures alongside them, on the other hand, charge carriers from the semiconductor substrate outside the field register(s) will migrate to them. These charge carriers may be thermally generated "dark current", for example. In either case the side charge transfer channels do not have adjacent charge transfer channels that the other charge transfer channels in the field register(s) do, leading to undesired edge effects in the outputs of these side charge transfer channels.

  • Technique for verifying genuineness of authenticating device
    Patent number: 4526466
    Abstract: A given type of authenticating device operates as a diffractive subtractive color filter that exhibits a reflectivity spectrum that includes a peak occurring at a wavelength that varies as a substantially linear function of the angle of incidence of polychromatic illuminating light having a particular polarization. The verification technique involves simultaneously illuminating a sample device over a range of angles of incidence by the polychromatic light, and then employing the reflected light from the sample to illuminate a reference device known to be genuine over the same range of angles of incidence. A sample device is indicated as being genuine only if both the respective intensity ratios of the light reflected from the reference device to the polychromatic light and to the light reflected from the sample device exceed respective threshold values.

  • Transient signal suppression circuit
    Patent number: 4525635
    Abstract: An input signal is applied to a first flip-flop whose output is coupled to the input of a second flip-flop. The two flip-flops are clocked, at a time t.sub.1 and at a subsequent time t.sub.2, for storing the value (SI.sub.1) of the input signal at time t.sub.1 in one flip-flop and for storing the value (SI.sub.2) of the input signal at time t.sub.2, in the other flip-flop. Logic gates coupled between the first and second flip-flops and a third, set/reset, flip-flop sense the values (SI.sub.1 and SI.sub.2) of the input signal stored by the first and second flip-flops and either: (a) set the third flip-flop to a condition indicative of the value of the input signal at times t.sub.1 and t.sub.2 if SI.sub.1 is equal to SI.sub.2 ; or (b) maintain the third flip-flop undisturbed in the state to which it was set just prior to t.sub.1 if SI.sub.1 is not equal to SI.sub.2.

  • Automatic adjustment of the amplitudes of plural-phase CCD clocking voltages
    Patent number: 4524450
    Abstract: In a plural-level gate metallization CCD shift register the clocking voltages applied to the levels are automatically supplied differential offset biases to cause the potential wells to have uniform depth. The differential offset biases are developed responsive to the differences in the threshold voltages of insulated-gate field effect transistors integrated on the same semiconductor substrate as the CCD shift register so as to have their gate electrodes in the different levels of gate metallization.
