Title: Device for data communications between wireless application protocol terminal and wireless application server, and method thereof
Inventor: KIM YONG-SUK
IPC: H04Q7/36
Filed: 1999-04-29
Abstract: A device for data communications between a Wireless Application Protocol (WAP) terminal and a WAP server, and a data communication method thereof. The data communications device includes: a plurality of WAP terminals each having a protocol stack in which a Circuit Switch Data service (CSD) protocol layer is laid under a Wireless Transaction Protocol (WTP) layer and a Wireless Datagram Protocol (WDP) layer, for generating WAP data which is service request data; a plurality of WAP servers each having a protocol stack in which a Transmission Control Protocol (TCP) layer and an Internet Protocol (IP) layer are laid under a WTP layer and a WDP layer, for providing the WAP terminals with WAP server data according to the WAP data; and an interworking function (IWF) unit having a CSD protocol layer connected to the CSD protocol layers of each WAP terminal, and a TCP layer and an IP layer which are connected to the TCP and IP layers of each WAP server, for mapping the WAP terminals to the corresponding WAP servers, wherein each WAP terminal communicates with the IWF unit though a single Internet Protocol/Peer-to-Peer Protocol (IP/PPP) layer included in its own CSD protocol layer, and the IWF unit communicates through the Internet with each WAP server. Because there is no redundancy of IP/PPP protocol layers in the WAP terminal, overhead is considerably reduced. Also, the IWF unit is directly connected through the Internet to the WAP server, not through the PSTN and the ISP, so that connection time and costs can be reduced.

Title: Space-saving ergonomic mousepad
Inventor: KIELLAND PETER JOHANN
IPC: G09F23/00
Filed: 2002-06-04
Abstract: A miniature mousepad adapted to rest directly on top of the keys of a computer keyboard, thereby providing a more compact work area for data input and minimizing hand travel between the keyboard's alphanumeric keys and the mouse. The mousepad's weight is supported solely by the top surfaces of a subset of the keyboard's keys such as the numeric keypad keys and the cursor navigation keys. The mousepad is comprised of a composite platform having an upper layer glued to a lower layer. The upper layer is made of rigid, low-friction material, upon which the mouse is supported and operated. The lower layer is made of flexible, high-friction material, which prevents the composite mousepad platform from sliding over the tops of the keyboard's keys. For larger embodiments of the mousepad, a software utility may be provided that re-maps the function of keys covered by the mousepad onto exposed keys. Promotional messages or other graphical content may be printed on the mousepad's upper surface.

Patent CA-2398165-A1 (CA)
Title: Glazing pigment and method for the production thereof
Inventor: SOMMER GUNTER
IPC: C09C1/24
Filed: 2001-01-31
Abstract: The invention concerns a method for the production of a glazing pigment, wherein a multilayer film is produced by vacuum deposition of a base and the particles thus produced are fragmented into pigment particles of a desired size after the base is removed, whereby vapor deposition of a plurality of layers in separate locations is carried out inside an evacuable container and the base is moved along the vaporization sources. According to the invention, at least one carrier layer (A), especially a silicon oxide layer, and at least one metal oxide layer (B), especially a titanium oxide layer, are vapor-deposited on the base, especially a continuos metal strip.

Abstract: L'invention concerne un procédé de production d'un rouleau de nontissé en élastomère thermoplastique, qui consiste à former un nontissé (131) en forme de feuille en empilant des filaments d'élastomère thermoplastique filés à chaud sur un transporteur à courroie (115); à débourrer le nontissé (131) en le guidant vers un rouleau rotatif (2) disposé au-dessus de la zone de transfert du transporteur à courroie (115) et en l'enroulant autour d'un tube papier (132) pour former un rouleau de nontissé (130). Etant donné que la tension exercée sur le nontissé (131) agit quasi directement en tant que force de débourrage, le nontissé (131) ne peut être débourré que par application d'une tension minimale nécessaire sur lui. Comme conséquence, on peut produire un rouleau de nontissé (130) moins sensible au pli vertical associé à une tension de tirage d'au plus 0,25 g/cm/metuke (une unité de mesure de poids japonaise utilisée dans certaines régions de l'industrie textile) et moins sensible au changement de forme relative à une récupération différée.

Abstract: An electronic article surveillance and identification tag (1) and system is provided. The tag couples energy from a radiated energy source, which comprises first and second radiated signals. A  mixing member (4) in the tag mixes the first and second signals to produce a sideband of the first signal, which is re-radiated by the tag. The mixing member is activated by a controller (6) that switches the mixing member into and out of the circuit according to a code stored within the controller that is associated with an article to be identified. As the mixing member is activated and deactivated, the sideband is radiated in a sequential manner according to the stored code. A receiver detects the sideband, and a decoder recovers the stored code according to the sequence of received sideband emissions from the tag.

Abstract: La présente invention concerne des procédés et des dispositifs qui sont mis au point en utilisant des fonctions (F) de modélisation des sujets. Ces procédés et dispositifs conviennent particulièrement pour l'étude et l'interprétation de la croissance d'un sujet. Les paramètres de la fonction sont calculés pour donner une courbe optimale en adéquation avec les données du sujet et notamment des données de croissance anthropométriques se rapportant au poids, à la taille à la toise, au tour de tête en fonction d'une mesure d'âge (t). De préférence, le sujet est un bébé, et la mesure d'âge (t) est ajustée sur la gestation. Ces fonctions en adéquation peuvent servir à estimer les tailles du sujet à un âge différent défini, et les tailles estimées peuvent être soumises à analyse statistique pour déterminer ceux des facteurs qui ont été susceptibles, le cas échéant, d'affecter la croissance du bébé.
