Abstract: A bullet hit detecting target panel which is configured with at least one calibration trace having a resistance that is set, and/or adjusted, to meet the characteristics of the target panel, such as panel type, zone arrangement and resistance characteristics of the conductive layers. When the target is physically and electrically connected to a target controller, then a calibration procedure is entered by applying a conductor to one or more resistive calibration structures on the target panel. Electrical characteristics of the resistive calibration structures are measured, and used for setting a hit threshold for target zones on the target panel. After which the conductor may be removed and the target is ready to accurately register hits based on the established hit threshold.

Abstract: Disclosed is a reactive target system including at least one target panel supported by a respective target positioning unit, and a shooter communications device. The target panel includes first and second electrically conductive layers positioned between first and second outer reinforcement layers, and separated by an electrically insulating layer. The first electrically conductive layer includes a plurality of electrically isolated target zones and a corresponding plurality of electrical connection sites. The second electrically conductive layer provides a common conductor zone and a corresponding electrical connection site. Each of the electrical connection sites are configured to be pierced by and electrically couple to a respective electrical contact element of an attachment mechanism on the target positioning unit.

Abstract: A system and method of producing a directional output signal is described including the steps of: detecting sounds at the left and rights sides of a person's head to produce left and right signals; determining the similarity of the signals; modifying the signals based on their similarity; and combining the modified left and right signals to produce an output signal.

Abstract: A method of enhancing the intelligibility of sounds including the steps of: detecting primary sounds emanating from a first direction and producing a primary signal; detecting secondary sounds emanating from the left and right of the first direction and producing secondary signals; delaying the primary signal with respect to the secondary signals; and presenting combinations of the signals to the left and right sides of the auditory system of a listener.

Abstract: A system and method that reduces the perceptual effect resulting from ear occlusion include an electro-acoustic feedback network that produces phase canceling sounds in the ear, where a receiver and a microphone are located. A control mechanism controls the response of the feedback network to minimize distortion in the ear while maintaining a desired frequency response for external signals. Devices producing the external signal include hearing aids, personal sound devices, in ear monitors, communications headsets and hearing protectors. The integration of the above with these devices improves a user's perception of their own voice.

Abstract: A mixing machine comprising a housing having an upper portion and a lower portion, an attachment drive head extending downwardly from the upper portion of the housing, an attachment drive including an attachment drive shaft, the shaft being capable of driving a detachable mixing attachment, an adjustable drive train linked to the attachment drive for driving the attachment drive shaft, a motor mounted in the housing for driving the drive train, a shift lever assembly including a shift lever wherein movement of the shift lever adjusts the length of the adjustable drive train and thereby changes the speed of the attachment drive, and a mechanism mounted on the housing to prevent the shift lever from vibrating out of position during a mixing operation and to prevent a change in speed of the mixing machine.

Abstract: A disposable container adapted for a single daily use for storing and cleaning dentures when not worn is disclosed. The container, which is particularly suitable for use in hospitals and nursing institutions as well as at home, is characterized as being disposable after a single use, of simple, convenient but elegant construction, inexpensive and sanitary, and carrying its own individual supply of cleanser.

Abstract: A method of fabricating a lamp, wherein the lamp base is made by providing a polyhedral block of wood and cutting the vertical plane faces of the block to form vertically curved sides while still maintaining the straight shape of the faces in the horizontal direction.

Abstract: A method of fabricating a lamp, wherein the lamp base is made by providing a polyhedral block of wood and cutting the vertical plane faces of the block to form vertically curved sides while still maintaining the straight shape of the faces in the horizontal direction. The lamp shade is made from a plurality of nestable curved panels that are cut from a rectangular parallelepiped block. The panels are placed on a multi-faced form and their vertical edges are joined together to form the shade.

Abstract: A method for fabricating a sofa, wherein an integral seat and back is formed by joining the sides of the boards together using a form to create a surface having an upward back portion and a horizontal seat portion. The seat is supported upon a pair of spaced apart legs. A pair of arms is constructed from blocks of wood by cutting through each block to form a convex piece and a mating concave piece. The backsides of the two pieces are joined to each other in a vertically offset manner to form joint surfaces. The upper offset portion is cut off and the remaining arm is joined to the seat utilizing its joint surfaces.

Abstract: An electric bulb holder for supporting a bulb in an apertured panel includes a moulded plastic housing, a contact strip for effecting electrical contact with a bulb seated in the housing and a sheet metal stamping mounted on the housing. The housing includes smaller and larger diameter parts joined by a transverse wall, a locating rim for guiding the housing into the panel aperture and a skirt for effecting a seal about the panel aperture.
