Abstract: An adsorbent (2) is sandwiched by two films (4) from upper and lower directions; the two films (4) are bonded to upper and lower surfaces of the adsorbent (2). A   skirt portion (4A) extending in a lateral direction of the adsorbent (2) is formed in an outer periphery of each of the films (4) and dispersing openings (8) are formed between the skirt portions (4A). Then, a freshness--keeping liquid impregnated in the adsorbent (2) is gradually dispersed outside from each side portion (2A) of the adsorbent (2) through the dispersing opening (8), whereby the adsorbent (2) in the freshness-keeping device (1) is prevented from contacting directly food and the freshness of the food can be kept stably in a long period of time.

Title: Apparatus and method for depth image-based representation of 3-dimensional object
Inventor: PARK IN-KYU
IPC: G06T15/20
Filed: 2002-11-27
Granted: 2009-02-10
Abstract: A family of node structures for representing 3-dimensional objects using depth image are provided. These node structures can be adopted into MPEG-4 AFX for conventional polygonal 3D representations. Main formats of the family are DepthImage, PointTexture and OctreeImage. DepthImage represents an object by a union of its reference images and corresponding depth maps. PointTexture represents the object as a set of colored points parameterized by projection onto a regular 2D grid. OctreeImage converts the same data into hierarchical octree-structured voxel model, set of compact reference images and a tree of voxel-image correspondence indices. DepthImage and OctreeImage have animated versions, where reference images are replaced by videostreams. DIBR formats are very convenient for 3D model construction from 3D range-scanning and multiple source video data. MPEG-4 framework allows construction of a wide variety of representations from the main DIBR formats, providing flexible tools for effective work with 3D models. Compression of the DIBR formats is achieved by application of image (video) compression techniques to depth maps and reference images (videostreams).

Abstract: Apparatus and methods for conditioning and pre-tensioning soft tissue grafts during joint repair surgery. The inventive apparatus (10) is configured so as to enable a surgeon to independently apply a desired tensile load onto individual strands of a multiple-stranded soft tissue graft. The inventive methods ensure that each strand of a multiple-strand soft tissue graft is adequately tensioned so as to both "condition" the graft to prevent subsequent stretching, relaxation or elongation following surgery, and pre-tension each strand of the graft to a desired amount so that each contributes to the strength and stability of the joint. The inventive tensioning device is equipped with structure (72) for attaching the device to a patient's limb during the procedure. It has multiple adjustable tension applicators (22) that can be independently manipulated so as to independently apply a desired tensile load onto one or more strands of the soft tissue graft.

Abstract: A seatbelt assembly (110) with a buckle has male and female mating parts (26, 28), in which the male part includes features to prevent disengagement operation by a child. The child resistant features include added ribs (40, 50), webbing (60) in the form of flanges or struts (70), or barbs (14) or prongs that increase the difficulty for disengaging the buckle. The female part can have an arcuate outer surface (44, 45) to increase the overall durability of the buckle and resist damaging external forces or damaging misuse. The female part can also be provided with lateral shoulders (112) to make the female part harder to withdraw and thus more child resistant. The seatbelt assembly with the child resistant buckle can be operated easily by an adult, while remaining secure from disengagement by a typical child.

Abstract: La présente invention concerne la parties commutée par paquets d'un système de communication mobile dans lequel au moins deux opérateurs de réseau partagent le même réseau. Aux fins de permettre à ces opérateurs de se concurrencer entre eux, ils possèdent habituellement un noeud de transit (GGSN1, GGSN2) propre, bien qu'ils partagent le noeud de desserte (SGSN1). Afin de permettre la sélection de ce noeud de transit (GGSN1, GGSN2), cette invention consiste à maintenir des informations concernant des réseaux partenaires prédéfinis, c'est à dire des réseaux partagés qu'un opérateur utilise en plus de ses propres réseaux. A partir de ces informations une station mobile (MS2) peut être connectée à un noeud de transit (GGSN2) de son réseau local (PLMN2), à condition que le réseau visité (PLMN1) soit un réseau partenaire de ce réseau local (PLMN2). Une station mobile visiteuse extérieure aux réseaux partenaires peut néanmoins être connectée au noeud de transit visité (GGSN1).

Abstract: The present invention employs approximate device locations determined from changes in the sensed strength of radio signals at different locations. In one instance of the invention, the approximate device locations are based on inference procedures that are used to process ambient commercial radio signals, to estimate a location or a probability distribution over the locations of a device. In another instance of the invention, approximate device locations derived from learning and inference methods that are applied to rank vector of signal strength vectors are utilized. Moving to such rank orderings leads to methods that bypass consideration of absolute signal strengths in location calculations. The invention utilizes approximations for a device location that is based on a method that does not require a substantial number of available ambient signal strengths while still providing useful location inferences in determining locations. Several location-centric services are supported, including receipt of location- specific information such as traffic reports, emergency information, transmission about device location, and time-sensitive promotions such as discounts offered by businesses for load balancing the provision of services.

Abstract: Selon cette invention, le revêtement externe (100) d'un corps aérodynamique (40) comporte des perforations (200) disposées selon des motifs précis en groupes ou paquets (250) respectifs s'étendant dans le sens de l'envergure. Chaque perforation est de préférence une micro-fente dont la longueur est comprise entre 100 et 3000 µm et la largeur est comprise entre 50 et 250 µm. L'air est aspiré à travers les micro-fentes depuis la couche limite d'air passant sur le revêtement externe de manière qu'on obtienne un contrôle de la couche limite. Dans chaque paquet, le motif, la taille, l'orientation ainsi que d'autres paramètres des micro-fentes sont conçus pour produire une interférence destructrice mutuelle des perturbations de flux provoquées par l'aspiration afin que l'excitation des instabilités de flux soit réduite au minimum dans le flux d'air de la couche limite. Le spectre spatial du motif des perforations d'un paquet donné est en particulier essentiellement dépourvu d'énergie importante à des longueurs d'onde prédéfinies d'instabilités de flux prédéterminées qui sinon apparaissent dans le flux d'air de la couche limite. Le corps aérodynamique comprend également des nervures de renfort (300) qui s'étendent parallèlement aux paquets (250) de perforations ainsi qu'une plaque intérieure (400) perforée permettant d'obtenir un contrôle de réglage du flux d'aspiration à travers les groupes de paquets.
