Abstract: An electronic reminder device for sensing approaching customers and playing a prerecorded message is provided. The electronic reminder device comprises a housing having a front surface, a first side surface, and a second side surface. A sensor mechanism is mounted to the front surface of the housing with the sensor mechanism detecting movement within a predetermined range. A recording mechanism records a message. A speaker audibly conveys the recorded messages. Upon the sensor mechanism determining movement within the predetermined range, the recorded message automatically plays through the speaker.

Abstract: A rotor such as a blisk B is balanced by determining the extent of any static or couple unbalance when the rotor is rotated about a test axis X while supported at a location surface 10 at which the rotor is supported in normal use. The location surface 10 is then modified, for example by removing material in a final machining operation, to eliminate the unbalance. For example the swash of the surface 10 may be altered and/or modification may be made to other location features (11) in order to cause the rotor to rotate, in normal operation, about an axis which is eccentric to the test axis X.

Abstract: A unitary, one-piece chair mat has a substantially planar upper surface suitable for interaction with a chair support structure, a perimeter defining an outer edge of the mat, a lower surface parallel to the upper surface. The mat is divided into a plurality of areas by at least two intersecting linear separation regions. The upper surface of the chair mat, including all said areas and regions, is smoothly continuous to an outer perimeter that joins the upper surface to the lower surface. The mat is foldable in alignment with the linear separation regions to occupy an area equal to or less than one forth of the chair mat upper surface area when disposed in an unfolded planar configuration.

Abstract: A transparent desk pad having substantially parallel upper and lower surfaces bounded by a perimeter, the upper surface providing an optically undistorted view of the transparent body lower surface that includes a physically disrupted portion for scattering light incident thereon to create an image such as of affiliation indicia visually perceivable through the upper surface

Abstract: A dock lighting system fixed adjacent to a doorway to provide navigational aid for truck operators has a substantially linear light source of low luminosity covered by a strip mounted over the linear light source of a brightly colored, translucent to transparent flexible material.

Abstract: A display rack includes a plurality of vertical rods having lower and upper ends. A plurality of inwardly directed arms have inner ends and have outer ends that are connected adjacent to the upper ends of the vertical rods. A core member joins the inner ends of the inwardly directed arms together. At least one horizontal loop is fixed adjacent to outer ends of the inwardly directed arms. Apparatus can maintain the lower ends of the vertical rods in fixed relation to each other. Each horizontal loop can include a plurality of downwardly depending hooks. Desk chair mats can be suspended from the horizontal loop, preferably by the hooks. An upstanding cylindrical graphics-bearing surface can be supported upon the inwardly directed arms. The rack can be supported on a rotatable base.

Abstract: A desk chair mat has a substantially planar upper surface suitable for interaction with a chair support structure, a perimeter defining an outer edge of the mat, a lower surface parallel to the upper surface. An array of generally blunt ended and laterally elongated projections extends downwardly from the lower surface for engagement with a carpet. A decorative pattern is also formed on the lower surface that is visible through the upper surface. Each projection has a smooth end surface spaced below the lower surface by a distance sufficient to penetrate into the carpet pile. The array is generally a regular pattern of the projections that can be arranged at an angle with respect to each nearest neighbor to provide enhanced resistance to lateral movement of the mat with respect to the carpet to protect the decorative pattern from abrasion.
