Abstract: The compact disk carrying case includes, in one embodiment, an outer enclosure which is defined by two clam-shell members. Each clam-shell member has an interfacing edge which mates with the corresponding interfacing edge on the other clam-shell member. A mechanism is provided, such as a zipper, for closing the interfacing edges thereby forming a closeable outer enclosure within which is captured a plurality of compact disks. The clam-shell members are hinged together along a portion of each respective interfacing edge. The carrying case includes a plurality of compact disk carrying plates which are grouped together into n end pairs of plates by n hinges. Each hinge has a progressively increasing span distance between the respective connected plates. Accordingly, these hinges establish minimum, a plurality of intermediate and a maximum span distance between the respective connected plates.

Abstract: The accessory carrier is mountable on a window visor of an automobile. The visor has a predetermined thickness and the accessory carrier is a three layer, generally planar, composite carrier having a thickness substantially the same as the visor thickness. One outer layer of the carrier has a longitudinal slot therein through which a tinted, planar viewing screen is laterally extendable. In another embodiment, an opaque sunscreen is stored in the carrier. The viewing screen or sunscreen has opposing sawteeth laterally extending from opposing sides thereof such that the sawteeth interact and coact with the terminal ends of the longitudinal slot of the outer layer of the carrier. The sawteeth provide digital or precise positioning of the screen with respect to the accessory as well as the window visor since the carrier is mounted on the visor itself. The accessory carrier also includes a closeable, longitudinal slot in the opposite outer layer. This layer is normally exposed to the occupant of the automobile.

Abstract: The reversible triangular box is a generally rectangular sheet divided into three rectangular sections, each containing a front and back face, by two major folds. Safety sign indicia is printed on one face while advertising indicia is printed on the other face. The minimal construction of the reversible triangular box includes two triangular side sections extending from the intermediate second section. Advertising indicia is printed on one face of each triangular side section and safety sign indicia is printed on the other face. A pair of complementary side locking tab and side locking slot combinations are utilized to removably couple or link a respective triangular side section to a first main box section. A minimal construction box has a first and a second handle portion, one of which extends from a top edge region of the first section and the other one extends from the top edge region of the third section. A retaining device holds the first and second handle panels together when they are juxtaposed.

Abstract: An EAS (electronic article surveillance) system and tag of type responsive to incident energy comprising EAS messages and other messages related to pricing and identification of articles includes circuitry for response to such EAS messages and for the receipt, storage and issuance of such pricing and article identification data, message generator apparatus for transmitting such EAS and other messages in the form of tag incident energy, and apparatus for interrogating the tags to cause such tag issuance of such stored pricing and identification data. An inventory store is responsive to issuance of tag stored identification data to decrement the inventory store and the use of article price totalizer apparatus responsive to the tag issuance of such stored pricing data. Further, the tag includes display apparatus for visual presentation of such pricing data.

Abstract: The foldable automobile window shade generally includes a first plurality of substantially rigid, planar elements joined together by hinges such that they form a first accordion fold portion of the shade. The shade also includes a second plurality of rigid, planar elements forming a second accordion fold portion of the shade. The shade also includes a hinge that links the first and second accordion fold portions. The hinge may be a pop-out tab in one of the elements forming the first accordion fold portion which cooperates with a through passage in one of the elements forming the second accordion fold portion. In another embodiment, the hinge may be a clip having depending and upstanding U-shaped legs that grip the elements in either the horizontal expansion mode or the vertical expansion mode.

Abstract: The foldable automobile window shade generally includes a first plurality of substantially rigid, planar elements, joined together by hinges such that they form a first accordion fold portion of the shade, a second plurality of rigid, planar elements forming a second accordion fold portion of the shade. The shade also includes a hinge that links the first and second accordion fold portions. The single hinge links end elements of the first and second accordion fold portions. In a horizontal expansion mode, the first and second end elements have planar surfaces that are adjacent to each other and the first and second accordion fold portions extend outboard from either side of the adjacent end elements. In a vertically expandable mode, the end elements are co-planar with respect to each other. The first and second accordion fold portions are disposed above the respective first and second end elements and therefore the shade can be vertically expandable as desired to cover the interior of the automobile window.

Abstract: Alarm tags releasably attachable to articles to be monitored in a retail installation or the like have enhanced operational capabilities giving rise to an improved likelihood of detection of article theft. The system has a transmitter unit which radiates signals containing diverse message contents. The tags each include an attachment device for releasably securing the tag to an article, a receiver unit for receiving such radiated signals and decoding the messages therein, an alarm unit and a signal processor, the latter being responsive to the state of the attachment device and to decoded messages for selectively operating the alarm unit to provide sensible output alarm indication.In a preferred embodiment, the system includes a transmitter in an exit area of the retail installation which radiates a signal containing a first message for receipt only by tags in such area and has a transmitter in a checkout area which radiates signals containing various selectable messages for article checkout purposes.

Abstract: In a method for electronic surveillance of articles in a given area, one preselects first and second zones in the area respectively for surveillance and non-surveillance and affixes to the articles devices adapted to provide a first output indicative of an alarm condition upon receipt of first predetermined signals and further adapted to provide a second output not indicative of an alarm condition upon receipt of such first signals together with second predetermined signals diverse from the first signals. One transmits the first signals in the area, and transmits the second signals at least into the second zone, such that devices on articles present in the second zone provide the second output. The first signals may be microwave and modulated low-frequency signals. The second signals may be unmodulated low-frequency signals. Systems and antenna configuration are also shown.

Abstract: A continuous loop transmitting winding assembly is disposed in one panel and a vertically oriented figure eight receiving coil winding assembly is disposed in a second panel, the two panels being mounted on pivots for swinging gate type movement straddling the pathway to be controlled by a magnetic surveillance system. This arrangement confines the surveillance field to the pathway and tends to follow the passage of an object bearing a marker therealong. No marker detecting backfield is generated. Alternatively, one winding assembly is moveable while the other is stationary thereby similarly confining the field.Special winding configurations are used to reduce interference from third harmonic signals produced in adjacent metallic counters. The arrangement also imposes immunity to signals emanating from cash registers, motors and the like.Door and single gate mounted magnetic and microwave surveillance systems are also disclosed.
