Disclosed is an anti-spying encrypted keyboard, particularly an anti-spying encrypted keyboard having an anti-spying detection protective system in multiple aspects. The anti-spying encrypted keyboard comprises a key panel and a main control board. The main control board includes a control circuit with self-destruct function. The control circuit is fixedly sealed on the back of the main control board by an anti-spying protective mechanism. The anti-spying protection mechanism is electrically connected with the control circuit. The anti-spying protection mechanism comprises: an anti-spying cover (31) having a bottom surface (311) and a side wall (312) extending perpendicularly along the edge thereof, the side wall (312) together with the bottom surface (311) forming a first cavity (313); a rigid anti-spying circuit board (32) being placed inside the first cavity (313), and a second cavity (326) being formed by a bottom side and a side wall with the circular edge, the bottom side of the second cavity (326) is provided with at least one pair of connecting fingers (3252) for the anti-spying circuit (32); and a conductive adhesive (34) placed inside the second cavity (326) to make the connecting fingers (3252) on the rigid anti-spy circuit board (32) and the connecting fingers (3252) on the control circuit of the main control board connect electrically.

A remote control unit for electronic apparatus comprises: at least a first plurality of keys (3) for controlling main functions for said apparatus, each labelled with a function symbol (4) ; a second plurality of keys (5) for controlling auxiliary or accessory functions for the apparatus; a microprocessor unit (6) operating on the first and second pluralities of keys (3, 5) and having a plurality of memory banks (7) for the corresponding settings of at least the auxiliary or accessory controls, referring to different makes and models electronic apparatus; means (8) for selection of the settings which act upon the microprocessor unit (6) ; at least part of the second plurality of auxiliary keys (5) is grouped on a circumscribed portion (9) of a surface (1) of the unit (100). The unit (100) further comprises a plurality of covers (11) with function symbols (12) referring to each key (5), and which may be attached, individually and in such a way that they can be removed, using means (10), to the circumscribed portion (9) when the apparatus to be controlled by the microprocessor unit (6) is selected using the selection means (8).

A communication terminal has a user interface having a keypad and display means, said key pad is included in a releasable housing part assembly, a processor controlling the terminal in dependence of the operation of the user interface, and identification means included in said housing part assembly for identifying the housing part assembly. The processor controls the display means in dependence of the identified housing part assembly.

The present invention relates to a high-reliability vehicle mounted device control apparatus (1) capable of making a decision about functions of switch units (4A-4G) with a simple structure and at a high processing speed and a low cost. Each of the switch units (4A-4G) comprises a circuit substrate having a required circuit pattern formed to include a plurality of pairs of short-circuiting possible land (L1-L3) portions, and a switch (4A-4G) mounted on the circuit substrate so that any one of the plurality of pairs of land portions (L1-L3) are short-circuited selectively to set a switching function inherent to that switch unit (4A-4G). Any one selected from the switch units (4A-4G) is mounted in one of the unit mounting sections (3A-3G), and the switch (SW1-SW7) of that switch unit (4A-4G) is turned on. A switch unit decision section constituting a control section (6) detects the land portions (L1-L3) short-circuited to automatically make a decision about the kind of a switching function of the mounted switch unit (4A-4G).

Coded interchangeable key pad assemblies alternately installed on a keyboard so that one of a variety of programmable sets of keyboard functions is enabled for selection by user actuation of the keys. Each key pad assembly has a durable construction and is securely attachable to the remainder of the keyboard. Each key pad assembly is installed on the remainder of the keyboard and interacts with the system with which the keyboard interacts, preferably a programmable system, to provide a custom key panel for the user so that key functions can be tailored to a desired selection of operations available to the user upon actuation of the keys.
