IPC: C40B60/14
Filed: 1997-03-14
Abstract: Techniques for patterning chemically or biochemically active agents on a substrate surface involve providing a micromold having a contoured surface including indentations defining a pattern and forming, on a substrate surface, a chemically or biochemically active agent or fluid precursor of a structure on the surface. A chemically or biochemically active agent or fluid precursor also can be transferred from indentations in an applicator to a substrate surface. The substrate surface can be planar or non-planar.      Fluid precursors of polymeric structures, inorganic ceramics and salts, and the like can be employed to form patterned polymeric articles, inorganic salts and ceramics, etc. at the surface. The articles, according to one aspect, are formed in a pattern including a portion having a lateral dimension of less than about 1 millimeter. Smaller dimensions can be achieved. The indentation pattern of the applicator can be used to transfer separate, distinct chemically or biochemically active agents or fluid precursors to separate, isolated regions of a substrate surface. The invention provides for inexpensive and simple synthesis of a combinatorial chemical or biochemical library.

Abstract: The invention relates to a system and a method to transmit data to a company's data system (23) by a mobile phone (20) connected to a mobile communications network, and receive an acknowledgement to the same mobile phone from the company's data system. Characteristic to the invention is that a preset target number dialed by a mobile phone is directed to an intelligent network centre (21), that the target number is decoded into data, which is transmitted to a company's data system during the connection. The intelligent network centre uses the caller's number identifying to check whether the caller is entitled to use the service, and to check to which information system of which company the data has been sent. The intelligent network centre transmits preferably by using transmits a telecommunications network signalling the target number, caller's number and address of the company's to a voice server (22), which is a computer capable also to identify telephone numbers and formulate voice messages. The voice server converts the target number into data and transmits the data and the caller's number to the company's data system using a data network, preferably a data network based on TCP/IP protocol. The company's data system stores the data in the data system and formulates a return message, which includes an acknowldedgement of the received data and further a possible additional information, and transmits it to the voice server using the data network. The voice server transmits using the mobile communications network the return message either as a GSM short message (text message) or as a voice message to the mobile station, which transmitted the data code, or as a pager message to the desired pager device.

Patent CA-2259317-A1 (CA)
Inventor: HARDTMANN DIRK J
IPC: B60R22/14
Filed: 1997-07-02
Abstract: A seat restraint system (110) whose torso belt (103) inflates upon impact to protect the occupants of a vehicle such as an automobile. The inflating component of the present invention is a braided tube (101) linked to a gas generator and crash sensor. When an impact is detected, the gas generator is ignited, inflating the braided tube. As the braided tube inflates, the diameter of the tube increases significantly and its length decreases significantly, due to the orientation of the fibers comprising the braided tube. The contracting tube pretensions the seat belt system by pulling any slack out of the seat belt system. The inflated structure restricts the forward motion of an occupant and distributes crash loads over a larger occupant surface area to reduce both primary and secondary injuries. In a side impact the inflated structure restricts occupant motion, distributes crash loads and provides head protection.

Inventor: LITTLER STEPHEN
IPC: A41D13/02
Filed: 1997-11-18
Abstract: L'invention concerne une combinaison (10) d'immersion essentiellement formée par une multiplicité de panneaux. Chaque panneau présente une couche (41) extérieure ininflammable et ignifugée et une couche (42) intérieure perméable à la vapeur d'eau et sensiblement imperméable à l'eau lors d'une immersion dans l'eau. Ces couches intérieures et extérieures (41, 42) de chaque panneau ne sont pas attachées dans une zone sensiblement continue de chaque panneau. Lorsque la combinaison est portée par un utilisateur immergé dans l'eau, les couches intérieures (42) empêchent l'eau de pénétrer dans ladite combinaison. Les couches extérieures (41) protègent les couches intérieures (42) lorsque la combinaison est exposée à un embrasement éclair. Ainsi, si l'utilisateur est par la suite immergé dans l'eau, les couches intérieures (42) peuvent encore empêcher l'eau de pénétrer dans la combinaison. Les couches intérieures et extérieures (41, 42) n'étant largement pas attachées (et non liées les unes aux autres), la perméabilité à la vapeur d'eau de la combinaison (10) s'en trouve maximisée, ce qui contribue à réduire la conduction thermique entre les deux couches (41, 42). En outre, des accessoires de combinaison tels que des poches peuvent être cousus sur la couche extérieure (41) uniquement. Les couches intérieures (42) n'étant pas atteintes par ces coutures, il n'est pas nécessaire d'étanchéifier ces couches intérieures (42) à proximité desdites coutures.
