Abstract: In a memory access control device (10) for use in controlling access by at least one address signal to a memory device (11) comprising memory modules each of which comprises a plurality of memory banks, a module checking circuit (16) checks first and second module signals indicative of the memory modules to produce a module coincidence signal when the first and the second module signals coincide with each other. First and second bank access checking circuits (17, 18) are assigned with first and second preselected number of memory modules and check first and second bank address signals indicative of the memory banks and first and second bank access held signals indicative of at least two of the memory banks which should be accessed. The first and the second bank access checking circuits produce first and second bank coincidence signals when the first and the second bank address signals coincide with the first and the second bank access held signals. An access judging circuit (191) alternatingly produces first and second inhibit signals in response to the module coincidence signal. The first and the second inhibit signals are also produced in response to the first and the second bank coincidence signals. An access signal output control circuit (20) inhibits supply of the address signal as first and second address signals to the memory device in response to the first and the second inhibit signals.

Abstract: In a continuous ink jet printer of the type in which drops can be deflected to a plurality of print positions, the path of undeflected drops is angled relative to the substrate 23 which is printed onto, so as to shorten the path of the most deflected drops. Since the most deflected drops are the least stable, this tends to increase print quality or allow greater printing speed. The plane of deflection of ink drops may be parallel to a circuit board 1 on which components of the print head are mounted, enabling a deflection electrode 15 and other electrodes to be formed directly on the circuit board, thereby reducing the number of components which have to be mounted separately onto the circuit board 1.

Abstract: An electrodeless high intensity discharge (HID) lamp system includes a ballast housing constructed from a thermally conductive material for containing a ballast of a type having at least one RF power switching device. The RF switching device is thermally coupled to the ballast housing to provide heat sinking therefor. The excitation coil of the HID lamp is also thermally coupled to said ballast housing via thermally-conductive coil mounting studs, but is electrically insulated therefrom. An opening in the ballast housing enables the electrical connection of the coil to the output circuit of the ballast. The RF power switching device and the excitation coil are arranged so as to be spaced apart sufficiently in order to maintain the ballast housing temperature substantially uniform during operation of said lamp, thereby maximizing lamp efficiency and increasing the useful life of the lamp and ballast.

Abstract: A system for authorizing access to a secured location, such as the vault of an automated teller machine (ATM) or the coin box of a pay telephone, without a key or combination for the secured location, and without requiring a fixed communication link extending to the location. A service technician receives a encoded access message which identifies a present access code previously stored at the secured location, the personal identification number (PIN) of the technician, and the identification number of a portable terminal assigned to that technician. The technician manually enters the encoded access message and the proper PIN into the terminal, where the identification number stored in the terminal and the manually-entered PIN are verified against the information encoded in the access message. If that information is authenticated, the technician then proceeds to the secured location and connects the portable terminal to a processor at that location. The encoded access message is transferred from the terminal to the secured location, where the access code previously stored at that location is compared with information contained in the encoded access message. The technician must also re-enter the proper PIN at this time. Access is granted only if all information is verified by information in the encoded access message. If access is allowed, the access code at the secured location is replaced by a new access code contained in the encoded access message, and that new access code is stored for the next authorized access to the particular secured location.
