Abstract: A dual-mode optical and RF reflector, and test system using the same. In one example the reflector is a mirror having a reflective surface including a first zone having a first surface precision, wherein a remainder of the reflective surface outside of the first zone has a second surface precision that is substantially lower than the first surface precision, the mirror being configured to collimate and reflect an RF signal from the reflective surface, and to collimate and reflect an optical signal from the first zone.

Abstract: A multimode radiation source is disclosed. One embodiment includes a waveguide radiator and an orthomode transducer coupled to the waveguide radiator to provide a first signal to the waveguide radiator. The waveguide radiator is configured to receive the first signal and to radiate the first signal at a first location as a first spherical wave signal with a first phase center. The multimode source also includes transmission medium coupled to the waveguide radiator and configured to radiate a second signal and a third signal from the first location as a second spherical wave and a third spherical wave with substantially the first phase center.

Abstract: Embodiments of a phased array antenna having a plurality of unit cells, each unit cell utilizing an improved electromagnetic band gap (EBG) structure and a lossy material in connection with the EBG element are disclosed. The lossy material reduces the undesired coupling between the antenna radiator and the EBG, thus providing enhanced scanning performance in the phased array aperture.

Abstract: An ETC igniter and compatible electrical connector for enabling an ETC gun to be used in a battlefield setting in close proximity with personnel and sensitive electronic equipment. This is accomplished by providing a current path to and from the igniter that is electrically isolated from all other portions of the gun. The connector and igniter are adapted to be capable of withstanding the high connection forces necessary to prevent arcing and the extreme stresses imposed during firing of the gun.

Abstract: A flag label for attaching to a product has adhesive faced transparent over-laminate and under-laminate layers on opposite sides of a printed layer. This assembly is releasably mounted on a release liner prior to use. The over-laminate defines an pressure sensitive adhesive backed tab portion demarcated by a tear line of perforations from a body portion of the label, which has pressure sensitive adhesive areas on its rear surface. The tab portion extends from the body portion and a portion of the body portion is unsupported by the product when attached.

Abstract: A reminder device for notifying a user when to take a dosage of medication. The credit card size device includes a first time counter for maintaining an elapsed program time and a second time counter for maintaining a current interval time. An alarm notifies the user of the expiration of the current interval. The user takes a dosage of medication in response to the alarm. A switch is provided for resetting the second time counter after the user takes a dosage of medication.

Abstract: A baseball bat which includes a handle part formed of metal, metal alloy or filter composite material, and a hitting part formed of wood. The hitting part may be of single-piece construction or may be formed of two or more pieces of wood connected by finger joints.
