Publication number: 20220221255Abstract: 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.Type: ApplicationFiled: March 3, 2022Publication date: July 14, 2022Applicant: Nielsen-Kellerman Co.Inventors: Alex J. Sitzman, Weston D. Petersen, Garet L. Itz, Ivan Dorflinger

Patent number: 11320447Abstract: An apparatus for measuring velocities of projectiles launched from firearms is disclosed. The apparatus includes a stationary clamp arm and a movable clamp arm works in concert with the stationary clamp arm for clamping the apparatus to a firearm. A thumb screw is employed to secure the movable clamp arm and the stationary clamp arm to the firearm. A sensor module, which is integrated to the stationary clamp, includes a first and second sensor coils, a first magnet adjacent to the first sensor coil, and a second magnet adjacent to the second sensor coil.Type: GrantFiled: June 19, 2020Date of Patent: May 3, 2022Assignee: Nielsen-Kellerman Co.Inventors: Garet L.

Patent number: 7249493Abstract: 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.Type: GrantFiled: June 7, 2006Date of Patent: July 31, 2007Assignee: Nielsen-Kellerman Co., Inc.Inventors: Richard Kellerman, Paul H. Nielsen

Patent number: 6257074Abstract: A portable hand-held vane anemometer is disclosed in which a modular vane assembly is removably mounted within the casing of the instrument. Within the modular vane assembly is a rotatably mounted impeller shaft. The impeller assembly preferably can be removed and inserted into a cavity of the anemometer. Consequently, if the impeller, bearings or other components of the impeller assembly should become damaged, the modular impeller assembly can be quickly and easily replaced. The vane anemometer of this invention may also measure temperature dependent environmental parameters and may also have the ability to measure these parameters relatively quickly and accurately when moving from one thermal mass to another thermal mass. These environmental parameters may include ambient temperature, wind chill, humidity and heat index. In order to determine these parameters, the vane anemometer may have a temperature probe and a humidity sensor that are disposed external to the casing.Type: GrantFiled: May 27, 1999Date of Patent: July 10, 2001Assignee: Nielsen-Kellerman Co.Inventor: Richard Kellerman

Patent number: 5357794Abstract: An improved speed transducer is disclosed. The present invention provides an alternating current coil speed transducer which utilizes the Faraday Effect to generate a voltage. The present invention discloses an improved amplifying circuit that amplifies the low voltages generated by small boats such as rowing shells to permit them to register accurate speed data at low speeds, e.g. between about 0.5 and 10 m/sec although higher speeds can be measured. The present invention also provides an improved technique for connecting a speed transducer to a boat that permits the speed transducer to be mounted and dismounted and the electrical connection broken without requiring extensive reworking of the speed transducer. In this regard, the present invention generally provides an improved technique for mounting and dismounting protruding apparatus that have electrical or other connections that extend into an object.Type: GrantFiled: June 12, 1992Date of Patent: October 25, 1994Assignee: Nielsen-Kellerman Co.Inventor: Paul Nielsen
