| 101 | Point of sale (POS) terminal security system | US10377188 | 2003-02-28 | US06917299B2 | 2005-07-12 | Shuzhen Fu; David C. Hanley; Raymond A. DeBruin; Jack R. Grenfell |
| A security system for electronic circuits (e.g. electronic circuits contained within a secure POS terminal) is provided that is both more tamper resistant, and tamper responsive and less expensive than the prior art epoxy potting. This is achieved by inserting an electrical connector between a first and a second circuit board contained within a case of the POS terminal. The first and the second circuit boards are any type of circuit board known in the art, including both not limited to, rigid circuit boards, flexible circuit boards, printed circuit boards, etc. If the case is opened the connector no longer provides an electrical connection between the first and the second circuit boards, triggering a tamper detection circuit. In some embodiments of the invention, a flexible conductive film is wrapped around the circuit boards and the connector. If a tamperer attempts to penetrate the case of the POS terminal to disable the tamper detection circuit, the circuit on the flexible security film is interrupted, in turn triggering the tamper detection circuit. As a result, the secure POS terminal of the present invention overcomes the limitations of prior art potted terminals. By eliminating the potting process, in fact, the cost of manufacturing the terminal is reduced and there is no need for a special ventilation system. In addition, the circuitry within the terminal can be accessed for repair and maintenance purposes. | ||||||
| 102 | Flexible magnetically coupled pushbutton switch | US10683618 | 2003-10-14 | US20050077988A1 | 2005-04-14 | Anthony Van Zeeland; Steven Shepard |
| A flexible magnetically coupled pushbutton switch assembly has a coupler layer magnetically held against a flexible layer that has flaps that function as flexible armatures. The flexible armatures are normally magnetically coupled to the coupler layer. The coupler layer is a sheet of magnetic receptive rubber material that includes debossed spacers, and there are embossed crowns in the flexible armatures. The embossed crowns fit into openings in the coupler layer so that a switch user may manipulate the flexible armatures. The debossed spacers support the flexible layer above a bottom layer such that there are armature cavities for the flexible armatures. An arrangement of electrical conductors is affected when a switch user selectively manipulates a flexible armature so that an electrical circuit connected to the electrical switch is opened or closed when the switch is actuated. | ||||||

| 108 | Intrusion detection security keyboard | US782466 | 1997-01-10 | US5872560A | 1999-02-16 | Hartmut Droege; Ludwig Fischer; Markus Scheibel; Dieter Sonnentag |
| A security keyboard is disclosed with a contacting circuit board, a plurality of keys and a switching foil, where the contacting circuit board comprises contact elements necessary for the security keyboard and which is substantially completely enveloped in a security film and in operating the plurality of keys the keyboard pressure is transmitted through the security film to the contacts of the contacting circuit board. In accordance with the invention, the plurality of keys are held in the switching foil in such a way that on operating the plurality of keys a tactile feedback is produced. This permits a positive switching of the security keyboard since, because of the tactile feedback, an `automatic` backpressure of the keys results through a force inflection point, after which an operating force necessary for the operation of the keys, increases again as a consequence, in part, of the security film lying between the key and the contacting means of the security keyboard. | ||||||
