Patent CA-2413729-A1 (CA)
Title: Flywheel system with parallel pumping arrangement
Inventor: WOODARD NATHAN G
IPC: H01J41/12
Filed: 2001-06-28
Abstract: A flywheel energy storage system (200), includes two pumps (218, 224) arranged in parallel for simultaneously drawing-off and absorbing substantially all of the gases that evolve from a flywheel assembly during high speed operation. A  water sorbent (224) has the primary purpose of pumping water vapor and a getter pump (218) has the primary purpose of pumping active gases. The parallel pumps, i.e., the water sorbent (224) and getter pump (218) are disposed in a gas storage chamber (214) that is separate from the main housing (202) of the flywheel system. A drag pump (216) pumps evolved gases from the main housing (202) to the gas storage chamber. Since the water sorbent has a relatively fast pumping speed as compared to the getter pump, getter material used with the getter pump degrades at a substantially slower rate thereby reducing the cost of using the getter pump.

Abstract: The invention makes it possible to drive a halftone image device and achieve high halftone reproduction by allowing at least one of the leading and trailing edges of a pulse width-modulated signal applied to a recording head, or forming amplitude- and width-modulated pulses, respectively, as driving pulses for placing one dot under halftone control, and changing a pulse width change of pulse width modulation in a stepwise manner, using the pulse width of the amplitude-modulated pulse as a unit pulse width.      The invention intends to achieve high-voltage and high-speed pulse output and low power consumption by converting input data such as halftone image data to a voltage signal, superposing pulse voltages of opposite polarities and applying the resulting signal to a switching circuit constituting an output state in the form of a switching signal, and also makes it possible to achieve high speed and high-voltage driving by connecting at least one of equivalent two-terminal elements in series to at least one of the respective driving elements of a complementary FET driving circuit, said equivalent two-terminal elements are each put on with a current of a certain or higher value passing therethrough to show constant-voltage characteristics and put off with a current of a certain or lower value passing therethrough to become a constant resistance.

Abstract: A network architecture includes a communication network that support one or more network-based Virtual Private networks (VPNS) (32a, 32b). The communication network includes a plurality of boundary routers (40a, 40b, 42a, 42b) that are connected by access links (35a, 35b) to CPE edge routers (34a, 34b) belonging to the one or more VPNs (32a, 32b). To prevent traffic from outside a customer's VPN (e.g., traffic from other VPNs or the Internet at large) from degrading the QoS provided to traffic from within the customer's VPN (32a, 32b), the present invention gives precedence to intra-VPN traffic over extra-VPN traffic on each customer's access link through access link prioritization or access link capacity allocation, such that extra-VPN traffic cannot interfere with inter-VPN traffic. By configuring the access networks (38a, 38b) the VPN boundary routers (40a, 40b, 42a, 42b) and CPE edge routers (42a, 42b), and the routing protocols of the edge and boundary routers, a high-level service of DoS (Denial of Service) attak prevention is achieved.
