Penetrating Projectile Alters Circuit Condition Of Target Formed Of Stacked, Penetrable Sheetlike Conductors Patents (Class 273/373)
  • Patent number: 11302213
    Abstract: A device, sometimes mobile, which simulates human motion, such as an omnidirectional sensing target. The target that can detect and differentiate between projectile (bullet) hits to the head, body, and one or more peripheral regions (e.g., arms, pelvis, legs) of a humanoid-form target, elicit a physical response from the mobile device based upon the sensing data, and provide real time feedback to a user (shooter) via a user-friendly interface. The target includes multiple layers of conductive material separated by one or more insulating layers. Forming can be by wrapping planar sensing panel into a three-dimensional configuration such that the panel occludes a three-dimensional volume and presents surfaces sensing projectiles from all directions. Associated circuitry is configured to have a bullet pass through multiple zones and to electronically detect the bullet path based on a combination and/or sequence of zones detecting bullet passage.

An indicator circuit has one terminal connected to the conductive member and another terminal connected to the conductive screen. The screen and conductive member are in relative close proximity so a fluid which flows through the screen will provide an electrically conductive path between the two conductive members.

    Abstract: A plurality of targets comprise two spaced metal screens secured in electrical isolation. A voltage is applied to the screens such that when the screens are shorted by a penetrating metal projectile, a pulse is produced having a pulse duration representing a particular type of projectile according to the length of the projectile. A logic circuit including a counter produces a count signal representing the pulse duration and applies this count signal to a CPU which compares the count signal to stored time intervals to produce a projectile identifying signal which is applied to a LCD display for describing the type of projectile hitting the target. A target signal generator generates a signal representing any one of the targets hit in response to a hit on that one target and supplies that signal to the CPU which generates a display signal identifying the target descriptively.

    Abstract: A novel dart game which allows one or more players to participate and which has a dart board mounted over a matrix switch and with segments to actuate the matrix switch when struck by a dart thrown by a player and which uses a first microcomputer to scan the matrix switch to detect where the dart struck the dart board and a second microcomputer which performs numerous functions such as totalizing the score for each player, actuating indicators which inform the players of the conditions and score of the game for each player. The novel dart board is formed with movable segments which are guided by guide ribs so as to provide smooth and accurate response of the segments to darts received on the board.

  • Patent number: 4244583
    Abstract: This invention is an electronic device for detecting, remote indicating, and accumulation of multiple penetrations of a target by conductive shafts such as hand-thrown darts, metal-tipped arrows, or similar missiles. The device utilizes a target comprised of layers of conducting foam pads separated by thin insulating layers. When these foam pads are penetrated by a conducting shaft, they activate an electronic logic system which displays to the player the score that his dart has made on the target.

  • Patent number: 4240640
    Abstract: An electrical, projectile penetration sensing target includes a pair of laminated sheets including a polymer resin coated brittle, calendered aluminum, wire screen and a polymer resin coated, fiberglass web, the laminated sheets being separated by and binded to a sheet of small celled foamed polypropylene. The outer faces of the webs have bonded thereto sheets of the foamed cellular polypropylene. The wire screens are electrically connected to a resistance responsive network whose output is a relatively wide pulse which is coupled to a recording device.
