  • Patent number: 11982517
    Abstract: Apparatuses, systems and methods for indicating whether a target has been impacted by a projectile are disclosed. Embodiments may include a microcontroller, an impact sensor, and an impact indicator. Apparatus may include an acoustic sensor and a miss indicator. Acoustic information or impact information may be received by the sensors and sent to the microcontroller unit. A determination may be made regarding whether the target has been impacted. An indication of a hit or a miss may be made by the impact indicator based on the determination. A light redirection element, which may include a light pipe, may direct light from the impact indicator around the edge of a target to a viewer.

  • Patent number: 7249493
    Abstract: A method and apparatus for measuring relative humidity of a mixture that provides a quick response time for thermal lag while affording protection to fragile sensors. In one aspect, the invention is a method for calculating the relative humidity of a mixture comprising measuring a chamber relative humidity (RHC) within a chamber enclosing an humidity sensor; measuring a first temperature (TC) within the chamber; measuring a second temperature (TA) separate from said chamber, said second temperature being the temperature of the mixture; and calculating the mixture relative humidity (RHA) based on the chamber relative humidity, a first value representing the first temperature and a second value representing the second temperature.

  • Patent number: 7153075
    Abstract: A press fit fastener (1) includes a shank (2), a head (3) and a press fit portion (4) being located at the shank (2). The head (3) is located at the first end of the shank (2). The press fit portion (4) includes a multiple helical profile (5). The helical profile (5) has a beginning portion (6) and an inclination portion (8). The outer diameter of the inclination portion (8) is designed to increase in a direction towards the head (3) to reach a maximum outer diameter. The maximum outer diameter of the inclination portion (8) is spaced apart from the head (3).

  • Patent number: 7059170
    Abstract: A method and apparatus for measuring relative humidity of a mixture that provides a quick response time for thermal lag while affording protection to fragile sensors. In one aspect, the invention is an apparatus comprising: a chamber having a membrane covering an opening in the chamber, the membrane being permeable to water vapor while impermeable to liquid water; a humidity sensor for measuring relative humidity of the mixture within the chamber; a first temperature sensor for measuring a temperature relating to the mixture within the chamber; a second temperature sensor for measuring temperature of the mixture at a point exterior to the chamber; and a processor for receiving signals representing the measurements taken by the humidity sensor, the first temperature sensor, and the second temperature sensor and programmed to calculate relative humidity of the mixture at the point exterior to the chamber as a function thereof.

  • Patent number: 6971662
    Abstract: A towing device (1) for motor vehicles includes an elongated element (2) having a length, a cross section, a first end portion (13) and a second end portion (5). The cross section of the elongated element (2) at least along a part of the length of the elongated element (2) is designed to be hollow. The first end portion (13) is designed to be connected to a motor vehicle. The towing device (1) further includes a lug (3) being connected to the second end portion (5) of the elongated element (2). Due to the hollow cross section, the mass of the towing device (1) is substantially reduced.

  • Patent number: 6935822
    Abstract: A detachable fastener includes a screw element and a securing ring. The screw element and the securing ring each include cooperating wedge-shaped surface tooth arrangements and two different pairs of stop surfaces. The wedge-shaped surface tooth arrangements face one another and form sliding surfaces sliding upon one another in a loosening direction of rotation resulting in an increase of the axial force. The first pair of stop surfaces transmits torque in a tightening direction of rotation. The second pair of stop surfaces transmits torque in a loosening direction of rotation. The stop surfaces are arranged with a clearance existing between one another such that the wedge-shaped surface tooth arrangements can slide upon one another without skipping.

  • Patent number: 6685409
    Abstract: A connecting element includes a screw including a head and a shank. The shank has an end, and it includes a shank portion, a threaded portion and a stop element. The threaded portion has an outer diameter, and it includes a thread runout facing the head. The thread runout has an axial extension and a circumference. The shank portion has a diameter which is less than the outer diameter of the threaded portion. The stop element is produced by removing the thread runout at least over a part of the axial extension and of the circumference of the thread runout in a way that the stop element has a diameter which approximately corresponds to the outer diameter of the threaded portion. The connecting element also includes a supporting element being captively connected to the screw and including a narrowing location having a diameter which is less than the outer diameter of the threaded portion.
