Title: Apparatus and method for encoding and decoding digital video data
Inventor: FUJINAMI YASUSHI
IPC: H04N19/102
Filed: 1996-07-23
Abstract: Digital video data encoder and decoder operate to enable the low and high speed reproduction of variable rate encoded digital video data by reproducing and decoding intraframe encoded frames that are identified by previously reproduced intraframe encoded frames. In the encoder, digital video data is variable rate encoded, for example, intraframe and interframe encoded, entry points (i.e., beginning positions) of selected encoded video data are identified and which represent video frames that occur at predetermined intervals of time (e.g., 1, 2 and 4 seconds) in the video picture. Entry point data that identify these positions are generated and added to the encoded video data before the video data is recorded on a record medium. When the encoded data is reproduced from the record medium, the entry point data is extracted therefrom and stored, and a successive intraframe encoded frame identified by the extracted entry point data is reproduced and decoded. The invention further provides for a record medium having thereon the encoded digital video data, and also provides for an encoder and corresponding decoder which encode and decode, respectively, digital still image and audio data in which entry points refer to each of the still images and also to particular intervals of time of the audio data.

Title: Surgical instruments and procedures for stabilizing the beating heart during coronary artery bypass graft surgery
Inventor: TAYLOR CHARLES S
IPC: A61B19/00
Filed: 1997-02-14
Abstract: The invention is methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. Pursuant to the invention, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles is effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all. Typically, in separate steps, the surgeon contacts the heart with the stabilizing means, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing means such that the contraction of the beating heart causes orgy minimal excess motion at the surgery site. By fixing the position of the stabilizing means in a configuration where the motion of the beating heart is effectively eliminated, the surgeon is able to stabilize the beating heart for the duration of the procedure. The stabilizing means may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention. In certain preferred embodiments, the stabilizing means is affixed to a semi-rigid support which is caused to become rigid, by any of a variety of techniques, such that the position of the stabilizing means becomes fixed by the support, and the heart remains substantially motionless for the duration of the procedure.
Patent CA-2199209-A1 (CA)
Title: Steam condensing apparatus
Inventor: STROCK THOMAS WAYNE
IPC: F28B1/06
Filed: 1997-03-05
Abstract: An air-cooled steam condenser that also uses heat pipe technology so as to provide steam tubes that are freeze proof under any ambient conditions and offer a simple approach to the management of noncondensable gases.  Steam flows through the main condenser with concurrent steam and condensate flow downward.          The heat transfer surface area and fan air flow are designed such that all of the steam does not completely condense and steam vapor continuously exits each tube row.  This continuous flow of steam vapor purges these rows of noncondensable gases.   The excess steam flows into the lower header to a secondary condenser section that utilizes heat pipes.  In the secondary condenser section,  the excess steam condenses on the evaporator side external surface of the heat pipes.  The noncondensable gases that remain in the lower header are vented with an air removal system similar to conventional condensers.   Condensate in the lower header is collected for reuse in the power generation cycle.

Abstract: A method of moving leaf objects and subtrees in computer networks that employ a distributed network directory is disclosed. The method employs the existing directories and an authentication procedure for each server. A first object that is under the physical control of the administrator of one partition of the distributed network directory requests access to a second object that is under the physical control of the administrator of another partition of the distributed network directory. The directory verifies that the access control list of the first object includes the second object. The access control list of the second object is then checked to verify that it includes a reference to the first object as an object that is permitted access to the second object.  As a result, access is only granted in response to requests from objects that appear in the access control list of the second object. A method of synchronizing the access control lists based upon an authoritative access control list is also disclosed.

Inventor: NILSSON LARS BERTIL
IPC: A61F11/14
Filed: 1996-01-30
Abstract: An earmuff and a method for changing the noise attenuation characteristic of an earmuff. The change is obtained by providing the foam-filled sealing ring (3) of the earmuff in the annular covering (5, 6) thereof with a large number of ventilation apertures (11) which are uniformly distributed along the sealing ring, thereby affecting the air spring action of the sealing ring. The ventilation apertures communicate with the environment without communicating with the interior of the earmuff. By reducing the air spring action to a considerable extent, the low frequency attenuation is improved. The communication with the environment provides "acoustic ducts", particularly by using special ventilation ducts (12)which can be dimensioned to give a selective noise transmission, dependent on the duct resonance, into the sealing ring, thereby affecting the noise attenuation characteristic selectively.
