Abstract:
Quick release bolt assembly (10) included shank (12) and head (14) of larger cross-section than that of shank (12). The screw thread of shank (12) is adapted to rotatably engage with a complementary screw thread in a nut. Disengagement means are adapted in use to disengage the head (14) or the nut without rotation of the nut or shank (12). The disengagement means includes a material (18) such as shape memory alloy or epoxy resin, adapted to change form to facilitate engagement when activated. Activation may take place by a direct power supply or remotely by a radio frequency, magnetic, ultrasonic or infra red signal. Bolt (10) can be used for anchoring seat belts. Computer systems and methods for the identification of a target, including enquiring as to the status of the target and having means to command the target to change the status are also disclosed and claimed.
Abstract:
A fastener (12) assembly for joining a first element (13) such as a circuit board to a second element such as a casing includes a first component (19) which has a pin (20) and a second component (24) which includes a cavity (28) for receiving at least part of the pin (20). Either the first component or the second component is made of a material adapted to change from a first shape to second shape at a particular temperature. The pin (19) of the first component is adapted to be locked into the cavity (28) of the second component when the second shape is attained through interaction of the material with the cavity. The heating means such as resistors (14) for generating the particular temperature may be included in the first element.
Abstract:
A contact device for an electrical component, particularly a connector, comprising at least one contact element, said contact element having a first contact portion located within said component and a second contact portion projecting downwardly beyond said component and adapted to be connected to a conductor, in particular of a printed circuit board by soldering, wherein said first contact portion consists of resilient metallic material, and said second contact portion separately manufactured consists of a shape memory alloy, said alloy having a transformation temperature which is significantly higher than the operation temperature of said contact device, said contact device being located or oriented, respectively, such that it is deformed towards said conductor, particularly of said printed circuit board above said transformation temperature.
Abstract:
Elément de compensation caractérisé en ce qu'il est constitué partiellement ou complètement d'un alliage pseudoélastique ou à mémoire de forme subissant de façon réversible des déformations importantes, même sous de très faibles contraintes et utilisé notamment dans les circuits imprimés.
Abstract:
On fabrique des connecteurs en appliquant la méthode utilisée pour les câbles plats. Une nappe de conducteurs (1a-1d) est recouverte sur les deux faces par des feuilles isolantes que l'on fait adhérer l'une à l'autre et aux conducteurs. Des lacunes sont réservées dans les feuilles pour laisser à nu des seqments de conducteurs. Après découpage et formage, on obtient des connecteurs qui peuvent revêtir une variété de formes pour une variété d'applications.
Abstract:
A connector has an insulating substrate (3) having a plurality of holes (6) and a desired first circuit pattern on it. Female contactors (2) are fixed around the edge of each hole (6) and have an opening whose edge is inwardly of the periphery of the hole, said female contactors being electrically connected to said first pattern. A male contactor component comprises an insulating substrate having a desired second circuit pattern thereon and a plurality of male contactor pins (1) fixed to the substrate and electrically connected to said second pattern, said pins being located in positions corresponding to the openings of the respective female contactors (2). The female contactors are made of a thin film of a shape memory alloy and the edge of each of the female contactors is given, before insertion of each of the male contactor pin, a shape memory such that the contactor (2) tends to return to a position to close or block the opening when said contactor is subjected to a temperature above the martensitic transition temperature. The pin (3) can thus be inserted at low temperature with little or no force, and yet is firmly gripped in service.
Abstract:
An active implantable medical device (AIMD) comprising an implantable electronics module and a tissue interface. At least one of the electronics module and the tissue interface comprises an electrically non-conductive, biocompatible and needle-piercable base having one or more biocompatible electrically conductive strands of conductive filaments stitched to the base. As used herein, stitching a conductive filament to a base refers to sewing, embroidering or otherwise securing the filament to the base through the use of hand or machine needlework.
Abstract:
Eine Verbindungsanordnung (10; 30; 40), besteht aus einem ersten Bauelement (11; 31; 41) und einem zweiten Bauelement (12; 36; 46), wobei wenigstens eines der Bauelemente (11, 12; 31, 36; 41, 46) zumindest teilweise aus einer Formgedächtnis-Legierung besteht und wobei zwischen den beiden Bauelementen (11, 12; 31, 36; 41, 46) eine kraft- bzw. formschlüssige Verbindung ausgebildet ist. Erfindungsgemäß ist vorgesehen, dass eines der Bauelemente (11, 12; 31, 36; 41, 46) der elektrischen Kontaktierung des anderen Bauelements (11, 12; 31, 36; 41, 46) dient.
