Patent CA-2619848-A1 (CA)
Title: Steering system
Inventor: MARUYAMA KOUHEI
IPC: B62D5/04
Filed: 2008-02-01
Abstract: A steering controller for an electric power steering device includes a base signal computing part for computing a base signal DT in accordance with at least the steering torque; a damper compensation signal computing part for computing a damper compensation signal in accordance with an angular velocity of an electric motor or a speed of steering wheel turn; and an inertia compensation signal computing part for compensating inertia and viscosity in the steering unit. The electric motor is driven by a target signal IM1 obtained by compensating the base signal with a damper compensation signal and an inertia compensation signal, to provide a steering auxiliary force. The target signal of the auxiliary torque is compensated so that a difference between a reference self-aligning torque of front wheel in a front wheel steering vehicle and a self-aligning torque of front wheel in an all-wheel steering vehicle is provided to a driver as a responsive feeling from the steering torque.

Abstract: The dust control system is adapted for use with a straw blowing machine.  The straw blowing machine typically starts with a bale of straw and utilizes a shredder to loosen the straw from the bale. A blower fan then blows the straw to a throat of a chute and the chute then directs the straw where desired. The dust suppression system includes at least one water inlet applying water to the straw before the straw exits an outlet tip of the chute. Water tanks are preferably provided which feed the water inlets in a controllable fashion to meter an appropriate amount of water to cause dust included with the straw to adhere to the straw and avoid degrading air quality when the straw is ejected out of the chute.

Abstract: Communication devices capable of at least two communication modes (e.g. WLAN, WMAN and WWAN and/or wired modes) can be configured to optimize communications using a policy--based mechanism to configure connections and routes. A rules engine evaluates its policies on a state change (e.g. network availability, time of day, etc.) to configure a routing table and, together with communication APIs, provides an appropriate connection to an application for its respective communications. Policies may be responsive to various factors such as Radio Access Technology (high/low bandwidth), cost, presence, time of day, location, application type and quality of service (QoS) requirements among others to optimize communications.
