  • Patent number: 5983949
    Abstract: A long flexible member which is subject to tangling is provided with a non-alpha-numeric code such as a color, textural, or design code, which code is used as an aid in untangling the item by providing a rough estimation of separation of sections along the length of the item. The code changes substantially continuously from one end of the member to the other and helps to identify which sections of the item may be close together. Untangling of the member is greatly facilitated by the code.

  • Patent number: 5936556
    Abstract: This novel computer input system consists of a keyboard with gojyuon-based key arrangements and software that is used in conjunction with the keyboard. The novel key arrangement of the keyboard of this invention uses the basic characteristics of the gojyuon table, but each key on the keyboard shows notations for both the Japanese gojyuon and English alphabet letter. For inputting Japanese, the column (or consonant) and the row (or vowel) of the gojyuon table are input in sequence. The gojyuon column keys are placed substantially on the right half of the keyboard, and the gojyuon row keys are placed substantially on the left half. The only letter consisting of a consonant in Japanese, (N), which is called hatsu-on, is input by pressing the key that represents the (NA) column of the gojyuon table with no vowels after it. Each letter of the English alphabet is assigned to the key that represents the same (or a similar) sound in the Japanese gojyuon row or column.

  • Patent number: 5280169
    Abstract: Method and apparatus for limiting optical radiation to an optical sensor are disclosed for protecting the sensor against damage from high intensity optical radiation. A fixed electric field is established between a pair of spaced electrodes by connection of the electrodes to a DC voltage source. Small solid particles oscillate back and forth in the electric field between the electrodes. Incident optical radiation is focused at a focal plane at the oscillating solid particles, and energy transmitted through the oscillating particles is focused at the optical sensor. The transmittance of the particle-containing space is substantially constant for incident optical radiation intensity up to a threshold level below which the sensor is undamaged by the radiation.

  • Patent number: 5004311
    Abstract: Beam scanning method and apparatus are shown comprising a cylindrical mirror upon which a focused beam is directed through the focus of the cylindrical mirror. The axis of the focused beam is pivoted about the focus of the cylindrical mirror for scanning the focused beam across the cylindrical mirror such that the axis of the focused beam reflected from the cylindrical mirror undergoes translational movement. A focus defect is introduced in the focused beam by reflection from the cylindrical mirror, the magnitude of which defect is a function of the angle between the optical axis of the cylindrical mirror and focused beam axis. Astigmatism is introduced in the focused beam directed onto the cylindrical mirror for at least partial compensation of the focus defect. By varying the astigmatism as a function of the angle between the optical axis of the cylindrical mirror and focused beam axis the focus defect may be eliminated when a parabolic cylindrical mirror is employed.
