Title: Vehicle violation enforcement system and method
Inventor: MARCHASIN CORY D
IPC: G08G1/01
Filed: 2008-02-15
Abstract: A vehicle violation enforcement and noticing system that includes a first server and a second server. The first server contains a vehicle information database that is in communication with the second server. The second server is a mobile data terminal that allows for the identification of vehicles and retrieves the vehicle information pertaining to the identified vehicles from the first server via a communications link. Once the vehicle information has been received, appropriate enforcement tactics are prepared based upon the received vehicle information. The appropriate enforcement tactics may include printing a notice informing a vehicle user of the current and outstanding debt associated with the vehicle for placement directly on the vehicle, writing a notice as per instructions displayed by the second server, for placement directly on the vehicle, booting the vehicle, towing the vehicle and/or informing a second agency of the vehicle location so that the second agency may take appropriate action.

Title: Outboard marine motor that allows a large steering angle
Inventor: INABA TAKESHI
IPC: B63H20/02
Filed: 2009-09-30
Abstract: In an outboard marine motor including an upper case (4) enclosing an engine (E) and a lower case (5) fitted with a propeller (12) and connected to a lower end of the upper case, the lower case is configured to be turned relative to the upper case around a vertical axial line which is coaxial with a vertical drive shaft (10) that transmit torque of the engine to the propeller. Thereby, the outboard marine motor can be steered simply by turning the lower case. Because the upper case having a relatively large lateral dimension as compared with the lower case is not required to be turned, a large steering angle can be achieved without the outboard marine motor interfering with watercraft having the outboard marine motor mounted thereon. In particular, the lower case is turned by an actuator including an electric motor and a worm gear mechanism (50) for transmitting an output torque of the electric motor to the lower case so that a high speed reduction ratio can be achieved by using a highly compact structure.

Title: Network transaction verification and authentication
Inventor: KUANG RANDY
IPC: H04W12/06
Filed: 2010-01-11
Abstract: A method for authenticating a security device at a local network location for providing a secure access from the local network location to a remote network location is described. At the security device, having a processor and a memory, a private security software is obtained from the remote network location, and the private security software obtains a user selectable personal identification number (PIN), and a global unique identifier (UID) of the security device. The PIN, the UID and the private security software are forwarded to the remote network location for generating a user-personalized credential code using the PIN, the UID and the private security software, including encrypting the user-personalized credential code. At the security device, the user-personalized credential code is obtained from the remote network location, and an authenticity of the user selectable PIN and the UID  is verified, without communicating over a network, including decrypting the user-personalized credential code, followed by retrieving access credentials to the remote network location. A  corresponding system is also provided.

Title: Fast computation of products by dyadic fractions with sign-symmetric rounding errors
Inventor: REZNIK YURIY
IPC: G06F17/10
Filed: 2008-08-28
Abstract: A product of an integer value and an irrational value may be determined by a sign-symmetric algorithm. A process may determine possible algorithms that minimize metrics such as mean asymmetry, mean error, variance of error, and magnitude of error. Given an integer variable x and rational dyadic constants that approximate the irrational fraction, a series of intermediate values may be produced that are sign-symmetric. The intermediate values may include a sequence of addition, subtraction and right shift operations the when summed together approximate the product of the integer and irrational value. Other operations, such as additions or subtractions of Os or shifts by 0 bits may be removed.
Patent CA-2700707-A1 (CA)

IPC: E02D27/32
Filed: 2010-04-16
Abstract: An adjustable concrete pier includes a concrete block having a central aperture extending from a top surface of the block to a bottom surface of the block. The pier includes a plate disposed at the top end of the concrete block, the plate having a hole aligned with the central aperture. An internal reinforcement framework is affixed to the plate and embedded within the concrete block. The central aperture receives a threaded rod to which is affixed a nut larger than the central aperture. A suitable support member, e.g. flat plate, U-shaped channel, etc., is disposed at the upper end of the rod.  The internal reinforcement makes the pier much stronger as the load bears on the plate and internal reinforcement. Because the threaded rod is not embedded within the concrete, it can be replaced. This novel design also permits greater vertical adjustability.

Inventor: MOUSSALLEM MICHAEL
IPC: G06Q30/02
Filed: 2010-06-02
Abstract: This invention provides a method and an apparatus that consumers can use to select retail merchants over the internet. Information is obtained from consumers about services and products they desire. Potential providers then view the consumer's information, and pay to make their own information available to one or more consumers they select on the basis of the consumer's description.  The consumers may then enter into a dialog with the providers to set up a merchant transaction. Thus, the system is driven by consumer's needs, and financed by the merchants. An advantage of this system is that by requiring the providers to pay for access to the consumer's information, the consumers are not inundated by large volumes of inappropriate and unwelcome solicitations. Instead, the merchants are self-selecting as being both able and financially eager to provide the desired products and services.
