Abstract: A dental X-ray positioning device includes a bite block for gripping receptor. The bit block may be adjusted to accept receptors of various dimensions. The bite block provides the clinician with greater freedom to accurately position the receptor relative to the X-ray source without having to utilize many different devices. The system thereby improves efficiency during X-ray exams and it also guarantees parallel placement of the receptor relative to the X-ray source and to the dentition being examined. The system also incorporates two soft “jaws” that during use prevent the receptor from drooping or failing to remain in parallel position relative to the bite block, the X-ray source, and/or the dentition.

Abstract: A construction toy system comprised of a plurality of molded plastic girders and connectors. The girder elements of generally square cross section, with interlocking elements extending axially from each end. The interlocking elements each comprise a flange of square configuration, a groove structure of squared configuration adjacent the flange, and a generally cylindrical rod-like extension projecting between the end of the girder body and the groove structure. Connector elements are formed with one or more sockets for receiving interlocking elements of the girders. The sockets have one open side into which the interlocking elements can be inserted with a lateral snap-in action. The flange portions are freely received in a slot formed in the socket, and the groove structure engages and cooperates with opposed locking ribs formed on the sidewalls of the connector socket. Opposed axial grooves in the socket sidewalls engage opposite side portions of the rod-like extension with a snap-in locking action.

Abstract: A system and method for generating pedestrian alerts are provided. Vehicle operators are provided with alerts regarding potential vehicle-pedestrian collisions and other dangers involving pedestrians. Additionally, pedestrians may be provided with alerts regarding potential dangers, including dangers of vehicle-pedestrian collisions. Mobile devices, which can be carried or worn by pedestrians, respond to activation signals from a vehicular device. The vehicular device receives positional information from each mobile device within transmission range, and determines relative positions of each of the mobile devices with respect to the position of the vehicular device. A determination of the probability of intersection of any mobile device with a warning zone near the vehicular device is calculated and predicted according to pre-determined rules. If the probability of intersection meets or exceeds a pre-determined threshold, an alert is generated.

Abstract: A device for stringing and supporting growing plants, such as tomato plants, and which is manually operable by a workman includes a handheld, elongated pole having a handle end, an opposite dispensing end, a tip member having an aperture and which is secured to the dispensing end, and a plurality of brackets having eyelets positioned adjacent the handle end and projecting perpendicular from the pole. Further included is a container for attachment to the workman's belt and disposed within the container is a rotatable ball of string which is dispensed from the container during the stringing of the plants.

Abstract: Apparatus is provided for controlling the pressure of gas in a plurality of dunnage bags. The apparatus employs an enclosure which houses a pressure regulator valve, linear air reset controller, pressure gauge, pneumatically activated electrical switch, and three-position valve for permitting quick filling of the dunnage bags from a high pressure inlet line. A low pressure line emerges from the enclosure and communicates with the bags. When the bags are at proper inflation, the electrical switch causes a green light to be illuminated. When the bags are inadequately inflated, the electrical switch causes a red light to be illuminated.
