    摘要: A gravity-actuated switch having a switch module with a switch housing and a lid. An electrically conductive pendulum is pivotally secured to the lid via a pivot pin so that the pendulum hangs within the housing and pivots with respect to the housing under the influence of gravity. A first electrical contact connectable to a power source abuts the pivot pin, which is electrically conductive. A second electrical contact is provided within the housing in a predetermined position such that the pendulum makes contact with it when the switch module is tilted by a predetermined amount. When the pendulum makes contact with the second electrical contact, a short circuit is provided across the pair of contacts, thus closing the switch. The switch is incorporated in a lamp assembly provided on the underside of the hood or trunk lid of an automobile to selectively provide power to a lamp so that the lamp is illuminated only when the hood or trunk lid is opened by at least a predetermined amount. A switch composed of a pivoting magnet and a magnetic switch can be used instead of the combination of the conductive pendulum and the curved electrical contact.

    摘要: A remote transmitting or receiving device (T/R device) communicates with a conventional subscriber telephone through available AC power wires which carry signals that may be modulations of RF carrier frequencies and which are coupled to the power wires. For example, an incoming telephone call includes signals that are detected and modulate a master RF carrier frequency which is coupled to the AC power wires at the telephone line location and these signals are coupled from the AC power wires at a remote R device location, and, demodulated and used to control an electrical appliance, motor, pump, etc. The remote T device which may be, for example, a fire detector produces signals which modulate a remote RF carrier frequency which is coupled to the AC power wires at the remote location and this modulated carrier is coupled from the AC power wires and demodulated at the telephone line location to control or initiate signals in suitable form for transmission over the telephone line. Thus, telephone calls to the subscriber's telephone line can be received at the remote location to turn on an electrical device at that location; or signals originating at the remote location initiate a telephone call and message from the transcriber's telephone line.

    摘要: A technique for detecting non-surface objects from a moving platform using radiant ranging. The platform moves perpendicular to a line through a pair of first and second transducers. A transmitter repeatedly transmits a radiant signal via a first transducer. The return reflection signals in both transducers include return reflection signals from sparse non-surface objects in the presence of surface clutter reflections. Respective synthetic aperture complex images of resolution cell in slant range and Doppler frequency are formed from the received reflections of the two transducers. The complex phase factor between received reflections for each resolution cell in the absence of non-surface objects is determined. This is feasible because the non-surface objects are sparse, that is rare and generally encountered individually. Each resolution cell of the first synthetic aperture complex image is multiplied with the complex conjugate of the corresponding resolution cell of said complex phase factor. The resulting product signal is subtracted from the second synthetic aperture complex image. The resulting signal is non-zero (except for second order effects) only in the presence of a non-surface reflecting target. The technique may employ a third transducer permitting detection of non-surface objects at otherwise blind heights.

    摘要: This relates to a lock arrangement particularly adapted for use in locking together closure panels of paper board cartons and the like. The lock arrangement utilizes a conventional basic type of lock including a primary locking tab and a secondary locking tab. The primary locking tab engages in a cutout having as part of its boundary a straight line primary locking shoulder. The new feature of the lock arrangement is an arrangement for receiving the secondary locking tab. This arrangement is in the form of a cut line which will define an opening through the associated closure panel and also define a secondary locking ear for engagement beyond a prong on the secondary locking tab. The closure panel in which the cutout and the cut line are formed is provided adjacent the cut line either with an opening or a hinged locking flap with there being between the cutout and either the opening or the locking flap a narrow strap. When a nose of the secondary locking tab engages the panel between the narrow strap and the cut line, the panel is locally bowed through a twisting of the narrow strap facilitating the opening of the panel along the cut line so as to automatically receive the nose of the secondary locking tab.

    摘要: A method and apparatus are disclosed for determining whether a shape or pattern exists anywhere in a particular image represented by a matrix of digital data signals. In the preferred embodiment, a suitably programmed general purpose computer provides means for storing the matrix of data signals representing the first image, computing the complement of the first image matrix and storing the complement image matrix, creating a structuring element representative of the target shape to be recognized and storing a matrix of digital data signals representing that structuring element, and creating a second structuring element equal to the window complement of the first structuring element and storing the second structuring element. One or more substantially identical neighborhood transformation stages are then employed for electronically eroding the first image with the first structuring element to form a first transformation matrix, and electronically eroding the complement image matrix with the second structuring element to form a second transformation matrix. The corresponding points of the first and second transformation matrices are then combined to form a result matrix wherein each non-zero point represents the location of the desired shape or pattern in the first image.
