  • Patent number: 8319950
    Abstract: A laser light receiver used to detect pulsed laser light that is produced by a rotating laser light source on a construction jobsite is disclosed. In this manner, the laser receiver acts as an elevation detector and provides an equipment operator, or a construction worker, with the current elevation status with respect to the plane of laser light. The laser receiver is a unitary device that can detect multiple light frequencies/wavelengths, including laser beams that are in the green, red, and infrared spectra. The laser receiver also is capable of discriminating between such laser beams and other interference light sources, particularly fluorescent light sources.

  • Patent number: 8286722
    Abstract: A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

  • Patent number: 8281495
    Abstract: A two-dimension layout system identifies points and their coordinates, and transfers identified points on a solid surface to other surfaces in a vertical direction. Two leveling laser light transmitters are used with a remote unit to control certain functions. The laser transmitters rotate about the azimuth, and emit vertical (plumb) laser planes. After being set up using benchmark points, the projected lines of the laser planes will intersect on the floor of a jobsite at any point of interest in a virtual floor plan, under control of a user with the remote unit. The laser light planes also project lines that will intersect along the ceiling at a point that is truly plumb above the crossing point on the floor. The laser planes also provide an “implied” plumb line that is projected in space, which is visible along a solid vertical surface to between the intersecting floor and ceiling points.

  • Patent number: 8239763
    Abstract: A method of defining and displaying letters of words on a computer platform is provided, so that words of text can be more quickly and accurately read by a person. A plurality of subfonts are used to define character sets to be displayed on a monitor screen, in which the subfonts make words more legible and faster to read. A font designer may design a variety of different subfonts for various characters of a font set, and can define which subfonts are to be used to display individual characters of words, depending upon the position of characters within a word, and depending upon the number of characters of that word. The font designer can select, from a plurality of subfonts, individual styles for letters of various words that are all defined within a same font set, which itself can comprise many different styles of existing or new font types.

  • Patent number: 8164419
    Abstract: An electronic lock box contains a secure compartment for storing keys to a structure. A linear actuator moves in one direction opening the door to the secure compartment, and moves in the opposite direction releasing a shackle that holds the lock box to the structure. A lock box system uses an encryption algorithm to diversify user PIN data at a central computer, and stores that diversified information on a memory card for later use when the user attempts to access a lock box. The central computer and electronic lock box both keep track of system “epoch time,” and the memory card must be presented to the electronic lock box within a correct epoch time window for the diversified PIN data to be successfully decrypted and compared to the user's PIN data that is entered on a keypad of the electronic lock box.

  • Patent number: 8151608
    Abstract: An electronic lock box contains a mechanical structure that allows the lock box to work in several different mechanical states. A first state is a key compartment door unlocking state, while a second state is a shackle release state. A third state is a “soft lock” state, which allows the key compartment door to be closed, or the shackle to be re-installed, and once this has occurred, the door will not fall open, and the shackle will not fall out. A fourth state is a “hard lock” state in which the key compartment door and the shackle are not easily disturbed by vibration or intentional impact by a would-be thief, who is attempting to unlawfully open the door or remove the shackle.

  • Patent number: 8082707
    Abstract: An improved vibration damping apparatus is provided for use with window structures, including windows used in vehicles, aircraft, and spacecraft. The vibration damping system includes at least two separate layers of solid material that are typically substantially clear at visible wavelengths, in which the two layers are spaced-apart by a predetermined distance to form a space or gap therebetween. This gap will be of a size and shape to enhance vibration damping when it is filled with a gaseous compound, such as air. The air-film vibration damping system created by the above structure can be applied to an external pane of a window structure, or to the interior pane of a window structure, or perhaps to both an exterior pane and an interior pane of the same window structure, if desired.

  • Patent number: 8051497
    Abstract: A head-covering apparatus is disclosed, which extends over the top of a human head and down its sides and toward the back of the neck. The apparatus has a forward extending portion with two pocket-style openings, the first pocket for receiving a flexible material that makes up the head-covering portion of the apparatus, and the second pocket for receiving the visor or bill of a baseball-style hat. The apparatus can be affixed to the visor/bill of a baseball-style hat and used in two different configurations: in the first configuration, the invention is “unfurled” so that its flexible material covers the human head and portions of the baseball hat; in the second configuration, the invention is compacted such that its flexible material is rolled or folded into a small compacted size, and then placed into the second pocket of the forward extending portion.

  • Patent number: 7997171
    Abstract: An attachment for a portable hand-held screw driving tool is provided for use with collated strips of screws. The front portion of the attachment is movable to a great extent, to thereby allow the tool to drive screws almost directly at the corner of two walls. A front “nose piece” is pressed against one of the walls, which causes the nose piece to move rearward “into” the remainder of the tool, in a “first stage” of movement. A screw is indexed to its drive position, and a drive bit is abutted against the screw head during this first stage. The nose piece is pressed further into the tool, which also causes a “feed tube” to move rearward “into” the remainder of the tool, in a “second stage” of movement, which rotates the screw as it is emplaced into the wall.
