Abstract: A freestanding exhibit display for supporting a banner includes a base, an upright support structure, and a transverse support arm. The upright support structure extends from the base. The transverse support arm is mounted on the upright support structure and includes a cradle defining a cradle space. The cradle is configured to retain a furled portion of the banner in the cradle space with only gravity.

Abstract: A method and apparatus for construction of a protective head covering, such as a helmet, to be worn by individuals engaged in activity that may, without the apparatus, cause concussive brain injury. The helmet, which is comparable in weight and envelope to conventional helmets, can be constructed from commercially available materials. The design features a dual shell concept where outer shell deflection under load triggers the primary attenuation mechanism. A second more rigid inner shell defines a space where one or more compartmentalized sealed elastomer energy absorbing cells are located. These cells contain a gas and/or liquid agent designed to adaptively convert potentially injurious normal impact force energy to energy that is channeled between the shells and therefore harmless to the wearer. A portion of this converted energy will be stored and then utilized to automatically re-set the apparatus for the next impact event.

Abstract: A lawn irrigation sprinkler head that internally incorporates an alert and retrieval device which indicates the position of the head if damaged, and facilitates in-situ repair of the damaged head. The sprinkler head has a hollow body containing a pop-up riser connected to a nozzle. The alert and retrieval device is positioned between the base of the riser and the nozzle. Should the nozzle become damaged or dislodged, the alert device telescopically extends from the riser and signals the location of the damaged sprinkler head. The device facilitates the repair of the head by lifting the riser from within the sprinkler head so that a replacement nozzle can be attached. In an alternative embodiment the alert device has an integral shut-off valve which prevents the discharge of water in the event that a subsequent irrigation cycle occurs before the damaged head is repaired.

Abstract: A device in the general size and shape of a golf tee, which contains sensing circuitry to detect the sound of the contact of the club head with the ball, or with the playing surface. This stimulus activates a timer, which in turn activates illumination device in the forth of a light pulse directed at the face of the golfer. By physical proximity to the target of the club head the golfer will perceive illumination of the device in his/her peripheral vision when the golfer has maintained eye contact with the target at the instant of contact.

Abstract: A windshield wiper blade design incorporating multiple sections, including one section of conventional wiper blade material and a second section of a lower coefficient of friction material. The first section contacts the windshield as the wiper blade is swiped, but as drag causes the blade to deflect (due to low or non-uniform moisture on the windshield), the second section gradually comes into contact with the surface. This lowers the average coefficient of friction of the blade and avoid excessive vibration. A number of embodiments are shown, all of which include a second section of material attached to the first section without creating an additional pivot point (additional to the apex). They alleviate oscillation of the blade as it wipes a windshield, thus eliminating squeaking, squealing, ineffective skipping across the windshield surface, and the resultant increased windshield wiper wear.
