Abstract: An advertising compliance monitoring system is provided that includes a tag affixed to a sign or marketing material or shopper ID card, the tag communicating with a reader on a periodic basis. The tag includes a memory for storing tag data, a transmitter and a receiver. The tag uses sleep modes to conserve power. The tag transmits tag data to a reader in response to an interrogation request, or automatically on a periodic basis. The tag data includes an identification number used to identify the tag associated with a particular sign, price, marketing material or shopper, status data (e.g., delivered, displayed), and time and date information. This data is processed by a central server to determine compliance with and/or exposure to a particular advertising program.

Abstract: A punch and backer plate combination is disclosed as an example of the present invention. The punch has a concave recess in its extended end. The punch may be round or have a rectangular shape in plan view and includes a backer plate having an aligned opening with a similar shape to the punch plus a clearance dimension. The aligned opening of the backer plate includes an upper portion and a lower portion, where the lower portion is enlarged in comparison to the upper portion to allow relief for a slug of material from the workpiece.

Abstract: A work board assembly having a board and hook assembly mountable to a rail assembly, and the rail assembly is mountable to a wall. A flip chart holder may optionally be hung on the board to add versatility to the board. The hook assembly is rotatable, thereby allowing opposite surfaces of the board to be easily and quickly exposed. The exposed surfaces may accept markers or the surfaces may allow tacking of documents, or one surface may be for markers and the other for tacking. The rail assembly includes a bracket designed to be attached to a wall and to mount a rotatable cam. The cam is received by a rail and rotation of the cam causes locking engagement of the rail to the bracket.

Abstract: A mobile shelving system having tracks and multiple shelf units for moving along the tracks. A shelf unit includes vertical posts that are attached to a carriage using fasteners that are part of the carriage. U-shaped clips connect to the posts and have slots that also accommodate flanges of shelves so that mounting shelves is facilitated. The shelves include a series of slits for receiving tabs that are part of barrier elements. The barrier elements act to limit movement of file folders stored on the shelves.

Abstract: A vertically and horizontally adjustable chair armrest is disclosed. The armrest includes an outer shroud, an upstanding support with a central opening and an armrest base. Within the central opening is a guide tube that moves vertically and has oppositely disposed slots. Within the guide tube, but mounted to rotate only, is a rod. At the lower end of the rod is a locking element that extends through the slots in the guide tube. The rod is rotated by a user pivoted lever bearing down on a spring biased activator nut. The nut is keyed to move only in a linear direction but is threaded to engage a mating thread on the rod, thereby causing the rod to rotate. When the locking element is rotated out of engagement with notches in the support opening, the armrest may be adjusted in a vertical direction. Releasing the lever allows the spring to bias the locking element into engagement with the notches to lock the armrest.

Abstract: A chair back is disclosed and includes a mesh material connected to a two-piece carrier, the carrier being deformable and stretchable. The carrier has a bottom edge including a groove and is engageable by tabs attached to a transverse member of a chair frame assembly. The upper ends of the carrier each includes an opening for receiving a spherical end portion of the upper end of the chair frame assembly. Engagement of the carrier with the chair frame assembly is accomplished by stretching the carrier and mesh between the transverse member and the spherical end portions. The chair back includes a lumbar support which is mounted to slide along the side edges of the carrier and along vertical supports of the chair frame assembly, the lumbar support causing the chair to tension forwardly. The chair back is pivotal under the influence of a chair user and is pivotally connected to the chair seat so as to cause the chair seat to also pivot in response.

Abstract: A body support system is provided having improved static and dynamic mechanical response characteristics and improved thermal regulation, and which can provide energy dissipation capabilities. The body support system can be of a modular construction to provide mechanical response characteristics suited to a particular user or group of users, or to a particular environment of use. The energy dissipation characteristics are provided by a flexible fluid compartment containing a volume of viscous fluid, such that at least a portion of the fluid moves within the compartment in response to a vertical force on the compartment.

Abstract: An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor coupled to the sensor for activating the sensor on a first periodic basis to measure the device parameter. The microprocessor includes a memory for storing the generated data signal representing the measured parameter. A transmitter and a receiver are coupled to the microprocessor. The microprocessor periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter.

Abstract: A pavement marking eradicator (10) for removing pavement marking from pavement. The eradicator has a grinding apparatus (13) having a safety skirt (31) to which is mounted a collector (39) of a vacuum system (14). The vacuum system also has a cyclone (36) for collecting and filtering debris created by the grinding apparatus during operation.

Abstract: There is disclosed herein a nuclear magnetic resonance apparatus for testing body fluids for a constituent, for example, blood for glucose. The apparatus includes a principal magnet, a magnetizable coil, and a circuit for energizing the coil for energizing and realigning molecules and detecting changes resulting from relaxation of said field and analyzing said changes. The apparatus is compact and adapted to receive and test an extremity or vessel carrying a body fluid. The coil is constructed to be positioned adjacent the extremity or vessel to be tested. Circuit means are provided for energizing the coil to energize and realign molecules adjacent said coil, so as to permit molecules adjacent said coil to assume an aligned position and for sensing changes in position when the coil is deenergized, which is indicated by spectra having peaks corresponding to various molecular bonds.
