Abstract: Engine (1) output speed is controlled for optimum efficiency by adjustment o f input speed of a continuously variable transmission (CVT) (3). Where power in excess of that provided by the engine (1) is requi red, additional power is input to the drive train from a fluidic motor (7) driven by fluid pressure stored in an accumulator (6). In driving conditions where the engine (1), operating at optimum ef ficiency produces power in excess of that demanded by the vehicle, the fluidic motor (7) is reversed for operation as a pump and excess engin e power is utilized to drive the pump (7) and store energy in the accumulator (6) in the form of fluid pressure. A CPU (18) determines power output required of the engine (1) as a sum of that indicated by a sensor (14 ) which senses power demanded of the vehicle by a driver and an increment of power required to maintain the pressure of the accumulator ( 6) above a threshold amount.

Title: Method and apparatus for encoding a video signal using feature point based motion estimation
Inventor: JUNG HAE MOOK
IPC: H04N19/423
Filed: 1995-05-06
Granted: 2005-06-21
Abstract: An apparatus for encoding a digital video signal (217) to reduce a transmission rate of the digital video signal, which comprises a feature point based motion compensation circuit (150) for selecting a set of feature points from the reconstructed reference frame to detect a set of motion vectors between a current frame and an original reference frame corresponding to the set of feature points by using a feature point based motion estimation, and for generating a second predicted frame based on the set of motion vectors and the reconstructed reference frame. The feature point based motion estimation employs a convergence process in which a displacement of each of the feature points are given to a motion vector thereof and the six triangles of each of the hexagon are affine-transformed independently using the displacements of their vertex feature points. If the displacement provides a better peak signal to noise ratio (PSNR), the motion vector of the subject feature point is sequentially updated. Therefore, the inventive convergence process is very efficient in the matching process to determine the predicted image as close as possible to the original image having zooming, rotation or scaling of objects.

Abstract: A system and method is provided for refilling a postage metering system that includes a host coupled to a postal security device (PSD). A user enters a first request for postage refill which is transmitted to a meter server. The meter server transmits a request for a PSD audit to the postage metering system. PSD audit data is signed with a first secret key stored in the PSD to produce an audit message that includes a first signature and the PSD audit data. The audit message is transmitted to the meter server which transmits the first signature to a key management system which then verifies the first signature using a second secret key stored in the key management system. The PSD audit data is verified at the meter server which then constructs a second request for meter refill and transmits it to a meter recharging data center. The meter recharging data center generates a refill combination and transmits it to the meter server. The refill combination is transmitted from themeter server to the key management system for signature using the second secret key to produce a refill message that is transmitted to the meter server. The refill message includes a second signature and the refill combination. The refill message is transmitted to the PSD which verifies the signature and the refill combination using the first secret key and credits the PSD for the amount.
