Title: Signal transmission process
Inventor: SCHEERHORN ALFRED
IPC: H04L9/32
Filed: 1997-09-17
Granted: 2006-08-15
Abstract: A method and/or system for transmitting sequences of signals/data from a transmitter to a receiver and for authenticating the sequences of signals/da ta may consist of a precalculation phase and of a communication phase in which the signals are transmitted together with the checking sums. In the precalculation phase , a pseudo-random sequence may be first generated by means of a cryptographic algorithm from a time-variable parameter and other initialization data. Non-overlapping sections (z(1) of a sequence (z) having each m bits may be associated to signals (s(i)), wherein i = 1, 2, ... n, of a signal storage. Further non- overlapping m bit sections (t(i)) of the remaining sequence may be selected for coding numbers (1, 2, ... MAX). The transmitter may transmit the initialization information and the ti me- variable parameters to the receiver and the receiver may calculate the pseud o- random sequence (Z) and checks the received authentication token (T). The transmitt er may accept the received signals as being authentic when the received authentication tokens match the calculated ones.

Abstract: The invention relates to an adjustable stop for a cutting element which is arranged in a tool base and adjusted therein. In addition to a hollow, slotted cylindrical stop body which can be expanded by an adjusting screw, the inventive device is provided with a sleeve which can be inserted into a longitudinal bore of said stop body. Said sleeve has an inner thread which engages with the adjusting screw, thereby enabling a higher load capacity of the threaded assembly. By enabling the sleeve to move in the direction of adjustment, flexional stress on the adjusting screw is reduced.

Abstract: A handle accessory includes an elongate rim mount having by parallel, spaced inner and outer flanges forming a downwardly directed receiving groove which is adapted to engage over and receive a bowl rim. A thumb rest extends outward from the outer flange along the lower edge portion thereof and centrally thereof. This rest has an upwardly curving outer end portion which tends to assist in retaining the thumb on the rest and preventing any accidental slipping therefrom. An upper flange, which is preferably coextensive with the length of the rim mount, tapers upwardly and inwardly relative thereto, providing a scraping edge against which the filled spoon can be easily slid to level the food, preferably no higher than the upper rim of the spoon. It will also be recognized that this upper flange an effective splatter shield for the outwardly positioned thumb. As a variation, the handle accessory can also incorporate an elongate support projection integral with the outer flange and extending from the lower edge thereof in alignment with the thumb rest. This support projection arcs downwardly and inwardly beyond the inner flange so as to underlie the side and bottom of the bowl for a substantial transverse portion thereof. In this manner, the support projection itself provides for a direct support of the bowl with or without an actual positioning of the hand beneath the bowl.

Abstract: The present invention relates to a pin structure for plug. The pin structure comprises: a first portion and a second portion. The first portion is made of a metal material for electrical connection. The second portion has a circumference, and two opposed sides. The circumference of the second portion is smaller than the first portion. The circumference of the second portion is covered with an isolation layer made of a plastic material for providing a safe and isolation surface. An aperture is formed through two opposed sides. The plastic material of the isolation layer can flow into the aperture to form the isolation layer so as to raise a fixed strength between the isolation layer and the second portion. Besides, the plastic material of the isolation layer can form on the two opposed sides simultaneously so as to shorten a forming time and to reduce the hesitation effect and weld line.

Abstract: A dome constructing method for constructing a spherical dome by assembling a polyhedral skeleton and then by finishing the interior/exterior of the same. A plurality of joints, which are to be arranged when assembled at the positions of the individual vertexes of a polyhedral skeleton and each of which has a plurality of joint blades in the directions of the individual sides of the polyhedral skeleton, as extended from said individual vertexes, and a plurality of frame members are adopted as members for constructing the polyhedral skeleton of the spherical dome. Three joints and three frame members are assembled into a triangular frame or a basic unit of the polyhedral skeleton in a grounded state by using the three joints as the vertexes and the three frame members as the individual sides of the triangular frame. Moreover, a new triangular frame is assembled around said grounded triangular frame by using similar frame members and joints, thereby to assemble the polyhedral skeleton of a polyhedral cone such as a pentahedral cone or a hexahedral cone, which uses the joints positioned at one vertex of said grounded triangular frame as its vertex and said grounded triangular frame as its one side. Each time the polyhedral skeleton of the polyhedral cone is thus assembled, a triangular frame different from said triangular frame is newly grounded by turning said polyhedral skeleton, and the polyhedral skeleton is subsequently assembled by repeating similar assembling works. Next, said polyhedral skeleton is finished on its interior/exterior to construct the spherical dome.
