摘要： A system for reading a data record stripe on a credit card which includes an injection molded case including a card guide slot integrally molded into the case near one side thereof and a read head window integrally formed in one sidewall of the card guide slot. A data read head assembly having a read head on a front face thereof is mounted in the read head window and is spring biased toward the wall of the card slot opposite the read head window. A circuit arrangement is coupled to the read head assembly for detecting data signals on a card passing through the slot and converting the data signals to a substantially square wave signal pattern representing binary signal data in the form of positive and negative signal transitions of the square wave signal. A microcomputer circuit coupled to the circuit arrangement is programmed to detect positive and negative signal transitions, to register in individual memory locations the time interval between successive signal transitions, and to reconstruct the binary signal data from the pattern of the registered time intervals.

摘要： Diffused light is projected onto a supported thin film in the form of a truncated sphere. The device has a light source disposed at the bottom end of a housing constructed of a light shielding material, and a diffuser plate at the top end of the housing to emit light into the truncated sphere. In one embodiment the plate carries a layer of liquid soap from which a bubble is blown. The housing may also carry a clear glass dome over its top end adjacent which the thin film is supported. Decorative interference patterns of luxuriant colors result.

摘要： A method for injection molding a transaction terminal case with an integral card slot formed by a knife blade in the female mold section which is supported against twisting during the molding process by a plurality of narrow buttress sections in the male mold section. The male mold section also includes a structural element in the form of a larger central buttress which contacts the knife blade of the female mold section cooperatively to form a read head window in one side of the integral card slot during the molding process. The male mold section further includes structural elements for forming a bracket mounting arrangement which is integrally formed adjacent the read head window during the injection molding process.
摘要翻译： 一种用于在阴模部分中由刀片形成的整体卡槽注射成型交易终端壳体的方法，该阴模模具部分在模制过程中被阳模模具部分中的多个窄支撑部分支撑在扭转状态。 阳模部分还包括形状较大的中心支柱的结构元件，其在模制过程中协作地接触阴模部分的刀片，以在整体卡槽的一侧中形成读头。 阳模部分还包括用于形成支架安装装置的结构元件，该支架安装装置在注塑过程期间与读头窗口相邻地整体形成。
