Patent number: 10066892Abstract: An automated weapon system comprising an active recoil control system, a bi-directional recoil containment and double strike prevention system and a mortar retention system. The active recoil control system uses multiple sensors in combination with a solenoid controlled multi-disc brake to adjust the weapon recoil. Using outputs from the sensors, a controller predicts and reacts to a recoiling mass performance and applies the required braking force, in order to compensate for anticipated or actual variations. Feedback from the sensors allows the active recoil control system to adjust braking during the recoil strokes and counter-recoil strokes in order to optimize the weapon operation and performance in extreme firing conditions.Type: GrantFiled: April 11, 2017Date of Patent: September 4, 2018Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Timothy Dacier, Thomas Tighe, Joshua Stapp, William Bartell, Matthew Tomik, Gary Mammolo, Noah Gordon, Edward Yuhas, Philip Floroff, William Hughes, Philip Wetzel, Jesus Quinones, Anthony Franchino

Patent number: 9546840Abstract: An active soft recoil control system that provides a bi-directional recoil containment and double strike prevention, which improves recoil force management, reduces the potential for “short” rounds, results in a more compact and lighter weight weapon, and increases the uniform performance of the heavy weapon at temperature extremes and steep cants. Furthermore, the present system provides for a mechanism that enables safer firing pin retraction and reduces the potential for unintentionally striking the primer and initiating the round during misfire operations.Type: GrantFiled: January 14, 2015Date of Patent: January 17, 2017Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: William Bartell, Thomas Tighe, Matthew Tomik, Noah Gordon

Patent number: 9470476Abstract: A retention system protects the round stored inside a rotating continuous belt-type magazine, and holds the round securely while allowing it to be readily and easily released prior to firing. The retention system permits all the retaining devices to be easily retracted so that a ramming mechanism of the weapon can push the round into the chamber without interference. The gun tube of the automated weapon houses the round and provides interfaces for all other components to attach. The tube length minimizes the axial movement of the round. The round is held within the tube by a front door assembly and a rear door assembly. The door assembly is made of a crescent-shaped door attached to a pivot shaft, in order to minimize the amount of rotational travel required to open the door for loading or firing the round.Type: GrantFiled: January 14, 2015Date of Patent: October 18, 2016Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Noah Gordon, Thomas Tighe, William Bartell, Matthew Tomik

Patent number: 7953325Abstract: An optical fiber network can include an outdoor laser transceiver node that can be positioned in close proximity to the subscribers of an optical fiber network. The outdoor laser transceiver node does not require active cooling and heating devices that control the temperature surrounding the laser transceiver node. The laser transceiver node can adjust a subscriber's bandwidth on a subscription basis or on an as-needed basis. The laser transceiver node can also offer data bandwidth to the subscriber in preassigned increments. Additionally, the laser transceiver node lends itself to efficient upgrading that can be performed entirely on the network side. The laser transceiver node can also provide high speed symmetrical data transmission. Further, the laser transceiver node can utilize off-the-shelf hardware to generate optical signals such as Fabry-Perot (F-P) laser transmitters, distributed feed back lasers (DFB), or vertical cavity surface emitting lasers (VCSELs).Type: GrantFiled: August 26, 2009Date of Patent: May 31, 2011Assignee: Enablence USA FTTX Networks, Inc.Inventors: James O.

Publication number: 20070178355Abstract: A fuel cell stack that includes an actuating device or devices for selectively providing interdigitated reactant gas flow and straight reactant gas flow through reactant gas flow channels to reduce water accumulation in the diffusing media layers of the stack. In one embodiment, the fuel cell stack employs internal actuators that selectively close the inlet end of every other flow channel and the outlet end of every other opposite flow channel to provide the interdigitated flow. In another embodiment, the interdigitated flow is provided by external actuation where two inlet manifolds and two outlet manifolds are provided. One input manifold is closed to close the input ends of every other flow channel and one outlet manifold is closed to close the output ends of every other opposite flow channel.Type: ApplicationFiled: January 27, 2006Publication date: August 2, 2007Inventors: Thomas Tighe, Mark Mathias

Publication number: 20070104986Abstract: A technique for determining whether a cooling fluid pump used for pumping a cooling fluid through a fuel cell stack has failed. The technique includes measuring the temperature of the cooling fluid at the output from the stack and/or measuring the cathode exhaust gas temperature as close as possible to the cathode outlet of the stack. The measured temperature is compared to a temperature that would be expected under the current operating conditions of the fuel cell system in a controller. If the difference between the measuring temperature and the expected temperature is large enough, then the controller provides a warning signal of pump failure, and also possibly reduces the stack outlet power.Type: ApplicationFiled: September 16, 2005Publication date: May 10, 2007Inventors: Thomas Tighe, Glenn Skala

Patent number: 7197244Abstract: Unlike the conventional art which polices data at the entry points of a network, a transceiver node can police or monitor downstream bandwidths for quality of service at exit portions of an optical network. That is, the transceiver node can police downstream communication traffic near the outer edges of an optical network that are physically close to the subscribers of the optical network. In this way, a network provider can control the volume or content (or both) of downstream communications that are received by subscribers of the optical network. In addition to controlling the volume of communications that can be received by a subscriber, the transceiver node employs a plurality of priority assignment values for communication traffic. Some priority assignment values are part of a weighted random early discard algorithm that enables an output buffer to determine whether to drop data packets that are destined for a particular subscriber.Type: GrantFiled: October 26, 2001Date of Patent: March 27, 2007Assignee: Wave7 Optics, Inc.Inventors: Stephen A.

Patent number: 7085281Abstract: A protocol for an optical network can control the time at which subscriber optical interfaces of an optical network are permitted to transmit data to a transceiver node. The protocol can prevent collisions of upstream transmissions between the subscriber optical interfaces of a particular subscriber group. With the protocol, a transceiver node close to the subscriber can allocate additional or reduced upstream bandwidth based upon the demand of one or more subscribers. That is, a transceiver node close to a subscriber can monitor (or police) and adjust a subscriber's upstream bandwidth on a subscription basis or on an as-needed basis. The protocol can account for aggregates of packets rather than individual packets. By performing calculation on aggregates of packets, the algorithm can execute less frequently which, in turn, permits its implementation in lower performance and lower cost devices, such as software executing in a general purpose microprocessor.Type: GrantFiled: October 26, 2001Date of Patent: August 1, 2006Assignee: Wave7 Optics, Inc.Inventors: Stephen A.
