Title: Method and apparatus for creating a television viewer profile
Inventor: BEDARD KAREN
IPC: H04N21/45
Filed: 1997-11-14
Abstract: A method and apparatus are disclosed for monitoring television viewing activity to determine preferred categories of programming (208) and channels of a viewer (202). To facilitate viewer access to preferred programming, the display of an electronic program guide (200) may be configured in accordance with the monitored viewing activity (204, 206) to provide fast access to preferred programming. The monitored viewing activity may also be used to provide a lock-out feature to prevent or limit the viewing of specific channels or categories of programming, or to identify and provide information of interest from the Internet. In yet another embodiment of the invention, a viewer may automatically circulate through his or her preferred programming, as is determined by monitoring the viewing activity of that viewer.

Abstract: The rivet includes a rivet body and a rivet shaft. The rivet shaft includes a shank with a head and an oval boss at opposite ends of the shank. The rivet body includes a circular flange with expandable arms extending therefrom with an oval aperture therebetween. The oval boss passes through the oval aperture and into cam grooves on the inner surface of the expandable arms. The oval boss, with its major axis positioned between the expandable arms, expands the arms apart into an installed position without the need for rotating the shaft subsequent to insertion. By turning the shaft one quarter turn after reaching the installed position, the minor axis of the oval boss is positioned between the expandable arms and the arms collapse to the uninstalled position. Additionally, complementary ramps and sheer faces on the lower surface of the head an within the countersunk nest surrounding the oval aperture inhibit relative clockwise rotation of the head in the installed position and urge the head upwardly from the flange in the uninstalled position.

Abstract: An egg server for cooked eggs in the shell. The server includes a bottom wall from which a sidewall extends, to form an interior which partially receives an egg. An inclined support face is formed within the interior to accommodate a wide variety of egg sizes, increasing the usefulness of the server. The lower outer face of the server may be of reduced size to nest within the interior of another of the egg servers, permitting multiple egg servers to be placed in a stacked position for storage. An upper rim of the sidewall may have a shape which mates with itself in an inverted position, permitting the upper rims of two egg servers to abut when the upper of the two egg servers rest upon the other egg server in an inverted relationship referred to as an insulating position. In this insulating position the two egg servers combine to encase an egg, retaining its heat prior to serving.

Abstract: A surgical instrument assembly has an endoscope with an instrument channel and a sheathed elongate tubular member inserted into the instrument channel. The sheath is provided with a distal end portion having at least one resiliently biased, curved portion tending to direct the tip of the distal end portion in a direction angularly offset from the axis of the body insertion tube at its distal end. The elongate tubular member is itself longitudinally slidably positioned within the sheath. The instrument channel exerts forces sufficient to straighten the curved portions of the sheath when the curved portions are positioned within the body insertion tube, proximal of the tube's distal end. An elongate flexible endoscopic instrument is mounted into the tubular member so that an operative tip is located at a distal end of the tubular member.

Abstract: La présente invention a trait à un procédé et à un système de surveillance, utilisés en particulier dans la surveillance de conteneurs (4). Chaque conteneur comporte une connexion radio à des satellites de localisation du type GPS (5), du type Satcom (6), ainsi qu'un équipement de télécommunications en champ proche permettant un transfert de données vers une unité de traitement de données. Ainsi, selon cette invention, plusieurs connexions radio possibles sont prévues entre des équipements individuels de télécommunications en champ proche; il est d'abord vérifié qu'une connexion peut être établie avec le satellite de localisation, et, si tel n'est pas le cas, une tentative d'établissement de radiocommunication avec le satellite de télécommunications est effectuée. Si celle-ci échoue également, une radiocommunication est alors établie avec un autre équipement de télécommunications en champ proche. Les conteneurs peuvent ainsi être surveillés et localisés à tout moment si, pour une raison donnée, une connexion radio est perdue. Si les conteneurs sont placés à des emplacements particulièrement difficiles d'accès, un mode de réalisation de l'invention comporte un équipement de télécommunications en champ proche qui n'est pas placé sur un conteneur, et qui permet de communiquer avec les conteneurs et avec les satellites.
