Abstract: A tent having an automatically stored window covering. As a window for the tent is moved from a closed position, where a fabric cover covers the window opening, to an open position, where the fabric cover is partially or fully removed from the opening, the fabric cover automatically stores itself. The only use effort to both open and store the fabric cover is in opening the fabric cover.

Abstract: A hinged door (26) is provided for a tent (20). The hinged tent door (26) in one embodiment includes a frame (46) for supporting the outer edges of the door. The hinged tent door (26) may include a removable frame (46) so that the door may be folded along with the tent into a compact configuration for storage. As an example, the frame (46) may be one or more poles (48, 50) that are removably attached to the door.

Abstract: A tool detection system combines a sensor nozzle with an ultrasonic transducer capable of propagating and detecting ultrasonic waves. A wave is propagated in a coolant fluid stream directed at a tool to be monitored. A control unit powers the ultrasonic transducer and contains circuits for analyzing the ultrasonic waves detected by the ultrasonic transducer. The control compares the actual time between the propagation of an ultrasonic wave and detection of an echo wave reflected from the tool, to an expected time. An alarm is generated when the tool is not present as indicated by the actual time exceeding the expected time. An alarm signal generated by the alarm generator either stops the tool or signals an operator that the tool is absent.

Abstract: An expandable insert for soft luggage articles, such as backpacks includes a pair of opposing planar insert panels interconnected by two web members. The web members may either be partially integrally formed from the insert panels or they may be separately formed. The web members are themselves also planar and each includes a foldline disposed therein between the opposing insert panels. At least one elastic band engages the two web members and provides an expansion force for the insert which draws the web members from a folded position into a generally planar position wherein they are generally perpendicular to the insert panels. The web members may include gusset portions which interconnect the web members to the insert panels.

Abstract: A flotation vest particularly adapted for use with children is provided in a vest body including a front panel and a pair of back panels each joined to the front panel so as to define an open back vest with a top neck opening and side arm hole openings. A head support portion is hingeably joined to the vest body along the neck opening at a forwardly displaced position. The head support portion includes left and right lobe-shaped collar portions extending on opposed sides of the neck opening to the top of the front panel. Continuous elongate opposing free edge portions extend the entire length of the back of the vest from the free end of the collar panels to the bottom of the rear panels. A releasable fastener requiring adult assistance for operation joins the opposing parts of the back of the vest to secure the vest to the child.
