Access control
An access control apparatus is provided. The apparatus can be used to unlock a device, wherein the device has a computation unit and at least one operator control unit that is electrically connectable to the computation unit, wherein the apparatus has a first reception unit for receiving electrical signals from the at least one operator control unit, a transmission unit for transmitting the electrical signals to the computation unit, a second reception unit for receiving at least one access message transmitted by means of an electromagnetic signal, an authorization unit for generating a switching signal if the result of the check on the access message is that unlocking of the device is permitted by means of the access message, and an unlocking unit for unlocking a transmission of electrical signals from the first reception unit to the transmission unit on the basis of the switching signal.
1. An apparatus for unlocking a device including a computation unit and at least one operator control unit electrically connectable to the computation unit, the apparatus comprising:
a) a first reception unit for receiving electrical signals from a first cable connectable to the at least one operator control unit;
b) a transmission unit for transmitting the electrical signals to the computation unit via a second cable;
c) a second reception unit for receiving at least one access message transmitted wirelessly by a wearable token device;
d) an authorization unit for generating a switching signal if a check on the at least one access message sent to the authorization unit from the second reception unit reveals that unlocking of the device is permitted by means of the at least one access message; and
e) an unlock unit for electrically connecting the first reception unit to the transmission unit to establish an exchange of electrical signals between the first reception unit and the transmission unit, on a basis of the switching signal, wherein establishing the exchange of electrical signals allows an operator to control the computation unit using the at least one operator control unit.
2. The apparatus as claimed in claim 1 , wherein the at least one operator control unit is designed as a keyboard or a mouse.
3. The apparatus as claimed in claim 1 , wherein the first cable is an electrically conductive cable, wherein the electrical signals are coded on a basis of a Universal Serial Bus (USB), PS/2 or RS-232 standard.
4. The apparatus as claimed in claim 1 , wherein the transmission unit is connectable to the computation unit via the second cable, which is an electrically conductive cable, according to a USB, PS/2 or RS-232 standard.
5. The apparatus as claimed in claim 1 , wherein the second cable is inseparably connected to the apparatus.
6. The apparatus as claimed in claim 1 , wherein the apparatus is at least partly arranged inside a casing and the computation unit is arranged inside the casing.
7. The apparatus as claimed in claim 1 , wherein the apparatus is at least partly arranged inside the at least one operator control unit.
8. The apparatus as claimed in claim 1 , wherein the unlock unit electrically connects the first cable to the second cable via the first reception unit and the transmission unit.
