Abstract:
A method and system for use in identifying customer premises equipment (CPE) in a distributed network are presented. The method includes receiving a first point-to-point-over Ethernet active discovery packet generating a device identifier code that identifies a product model of a customer premises equipment (CPE) device, and sending a second point-to-point over Ethernet (PPPoE) active discovery packet. The second PPPoE active discovery packet includes a tag that includes the device identifier code.
Abstract:
A computer implemented method includes sending a request from a customer service terminal to a broadband remote access server to retrieve a device identifier of a customer premises equipment device. The device identifier is received by the broadband remote access server via a point to point protocol over ethernet active discovery initiation packet sent from the customer premises equipment device. The computer implemented method includes receiving, at the customer service terminal, a response from the broadband remote access server that includes the device identifier of the customer premises equipment device.
Abstract:
A system for remotely monitoring an environment and selectively deploying munitions is provided. The system is comprised of sensors to monitor one or more select environments, one or more munitions deployment devices disposed in the selected environment, and an operator control unit (OCU) operable to communicate with the munitions deployment device(s) and sensors. Sensor data is communicated to the system, enabling a user to selectively deploy munitions disposed in or in communication with the munitions deployment device(s), based on the threat detected by the sensors. Deployable munitions include both lethal and non-lethal munitions. The munitions deployment devices may be deployed in a stationary location, or in mobile applications, such as on a robotic vehicle, and accommodate removably, electrically initiated munitions cartridges. Further, the deployment devices may be in wired or wireless communication with the system, allowing virtually unlimited scalability.
Abstract:
The present invention provides a burping projectile and, particularly, a non-lethal projectile having a nose-mounted fuze thereon, which initiates an expulsion charge via an ignition shaft in the payload cup of the projectile body at a preset distance from target impact, resulting in sufficient expansion of the projectile body via the forces of propellant gases to create an annular opening between the projectile body side wall and projectile body forward end. The payload is then ejected from this annular opening, the resulting forward velocity of the escaping payload producing a rearward thrust on the projectile, and a concomitant deceleration thereof to a non-lethal forward velocity or a total reverse in direction of travel.

Abstract:
A metal oxide-hydrogen battery having an outer metal pressure vessel that contains a plurality of cell modules. The vessel is composed of a cylindrical shell and the open ends of the shell are enclosed by dome-shaped heads. In producing the vessel, a weld ring is positioned between each end of the shell and the respective head and each weld ring includes a base which is engaged with the inner surfaces of the shell and head and a radial fin which extends outwardly from the base and is located between the opposed ends of the shell and head. A weld is made interconnecting the weld ring with the head and shell. The weld ring is free of internal spokes and the radial thickness of the weld ring is from one to six times the thickness of the vessel wall. With this construction, the weld ring will flex with the shell during cycling of the battery to prevent undue stress at the welded joint.
Abstract:
A coaxial terminal construction for a sealed pressurized battery. The battery includes a sealed vessel containing a series of battery cells and positive and negative poles are connected to the cells. A pre-assembled terminal unit extends through an annular mounting flange that is secured within an opening in the vessel wall and the pre-assembled unit includes an inner electode, an outer electrode, which is disposed concentrically outward of the inner electrode and insulated therefrom, and an annular mounting member which is located concentrically outward of the outer electrode and insulated therefrom. All three concentric members have external threads of the same pitch. The terminal unit is installed by threading the mounting member in the mounting flange of the vessel and simultaneously threading the outer electrode with a nut connected to one of the poles and threading the inner electrode with a second nut connected to the other of the poles. The mounting member can be crimped inwardly to provide a seal between the three concentric members.
Abstract:
An improved pressure vessel for a metal oxide-hydrogen battery which comprises an outer cylindrical shell and a battery cell is disposed centrally within the shell. A pair of sealed containers or tanks are located in the ends of the shell on either side of the cell and each container contains pressurized hydrogen. In a preferred form of the invention, a portion of each container constitutes a head of the vessel. Each container is provided with an opening which provides communication with the interior of the vessel, and a remotely controlled valve acts to open and close the opening. Opening of the valve permits hydrogen gas to contact the cell to generate an electron current in an exterior circuit. During recharging of the cell, hydrogen generated in the cell passes into the containers and is captured therein by closing of the valves, thereby minimizing self-discharge of the battery cell during standby periods.
Abstract:
A method and apparatus for adjusting a variable parameter of a dynamic system in response to a signal representative of the system performance so as to optimize system performance with respect to that parameter. A first signal related to system performance is extracted from the dynamic system and is thereafter coupled to a plurality of performance index blocks, each of these blocks for operating on this signal according to a different predetermined characteristic transfer function. The output level from a selected performance index block is periodically sampled and the sampled level is compared with a previously sampled level to provide a positive or negative difference signal. A first pulsed signal is formed wherein pulses and zero levels are respectively representative of the incidence of opposite polarity levels in the difference signal. This first pulsed signal is converted into a second pulsed signal wherein the leading and trailing edges of the pulses correspond to the incidence of adjacent pulses in the first pulsed signal. The zero axis position is shifted in relation to the second pulsed signal to obtain positive and negative signals whose width is representative of the extent to which the variable parameter of the dynamic system must be inreased or decreased. The positive and negative signals are integrated to provide an output signal for adjusting this variable parameter.
Abstract:
A mower blade assembly for a lawn mower, the assembly comprising a blade bar adapted to be rotated by the output shaft of the lawn mower, and a cutter blade subassembly secured to each of the opposite ends of the blade bar. Each cutter blade subassembly comprises a thin spring steel cutter member preferably of rectangular shape and preferably having a thickness in the range 0.010 to 0.025 inch. The preferred rectangular shape of the cutter blade provides four cutting edges, only one of which is used at a given time, but which may be used interchangeably by repositioning the cutter blade relative to the subassembly. The cutter blade is detachably sandwiched between the blade bar and an interchangeable propeller lift cap having an upwardly inclined end portion at the trailing end thereof relative to the direction of rotation of the blade bar. The propeller lift cap serves the dual function of (1) helping to retain the cutter blade in position on the blade bar; and (2) by means of its upwardly inclined end portion of providing a propeller action which lifts the grass before it has been cut to facilitate cutting of the grass, and also of lifting the cut grass to move it toward the discharge outlet of the lawn mower. The easy interchangeability of the propeller lift cap permits substitution of a propeller lift cap having an inclined end portion of different angular inclination and, hence, having more or less propeller lifting action, since different grass conditions require different lift; for example, wet spring grass requires more lift than dry fall grass.
