Title: Expandable bead molding ring for a tire mold
Inventor: KASPER BRETT ALAN
IPC: B29D30/06
Filed: 2002-12-12
Abstract: Apparatus and method for molding a tire (110) with an expandable bead molding ring assembly (250) having a two-stage movement from a retracted and disengaged state, to a radially expanded state, to an expanded and engaged state for molding a tire bead (112b). The two-stage movement is accomplished using a simple assembly of easily manufactured parts, and is driven by a simple continuous downward (axially outward) movement (320) of a hub (209) of a mold press (220). A combination of annular elements with springs converts the hub movement to the desired two-stage movement of segments (254, 256) of a segmented bead molding ring (252). Frustraconical cam surfaces (258, 266) are used to divide axially directed forces (420a, 420b) from the mold press movement (320) into radial force components (410a, 410b) and axial force components (415a, 415b) for causing corresponding radial movements (310) and axial movements (315) during the two stage movement. Spring resistances are balanced, and stopping surfaces are provided in order to control and properly sequence the two-stage movement. The elements of the expandable bead molding ring assembly are preferably assembled with a sidewall mold to form a single unit (280) that is easily maintained and easily switched in and out of the mold press for mold changeover to adapt to different profiles to be molded on beads of different tire constructions.

Abstract: A technique for allowing a first and second group of users to share access t o a communication channel such as a radio channel. A first group of users is typically a legacy group of users such as those using digital CDMA cellular telephone equipment. The second group of users are a group of data users tha t code their transmissions in different formats optimized for data functionalities. The first group of users share one modulation structure suc h as, on a reverse link, using unique phase offsets of a common pseudorandom noise (PN) code. The second group of users share another modulation structur e but in a manner that is consistent and compatible with the users of the firs t group. Specifically, the users of the second group may all use the same PN code and code phase offset. However, they are uniquely identified such as, f or example, assigning each of them a unique orthogonal code.

Title: Capacitively switched matrixed el display
Inventor: TAIT WILLIAM
IPC: H05B44/00
Filed: 2001-11-06
Abstract: The present invention provides a multiplexed matrix alternating current electroluminescent display, comprising an array of matrix addressed capacitively switchable electroluminescent pixels, with each capacitively switchable electroluminescent pixel including an electroluminescent pixel and a circuit element connected in electrical series with the electroluminesent pixel. The circuit element is switchable between an electrically insulating capacitive state and an electrically conducting state depending upon a voltage applied across the capacitively switchable electroluminescent pixel. The matrix multiplexed electroluminescent (EL) display with the low capacitance switching device in electrical series with the electroluminescent pixels reduces column displacement currents, thereby reducing power consumption. Refresh times can also be reduced so that the size and resolution of passive matrix electroluminescent displays can be increased.
