Title: Tamper-Resistant Vending Machine
Inventor: ODEN KENNETH W
IPC: G07F1/04
Filed: 1995-06-14
Abstract: A tamper-resistant door for a vending machine includes a conventionally-positioned product delivery port, a cash box vault positioned adjacent the delivery port for receiving a cash box, a coin return chute positioned at an upper corner of the delivery port, and a coin changer of conventional design positioned over the delivery port and the cash box.  A changer vault partially encloses the coin changer.  The cash box vault (and the cash box placed therein)  are relocated away from their conventional position on the non-hinged side of the main door to a location adjacent the product delivery port on the hinged side of the door, while the coin changer is relocated away from its prior art position adjacent the non-hinged side of the main door to a central location above the product delivery port and the cash box vault.  An elongated coin chute connects the coin return slot with the coin inlet of the coin changer.    A  first  section  of  the  coin  chute  is  in communication with the coin slot.   It incorporates both a longitudinal  drop at  its  inlet  end and a  sideways bend adjacent its outlet end, and is provided along its bottom with a plurality of drainage slots.   A second section of the coin chute is in communication with the coin inlet of the coin changer,  and angles downwardly to provide a vertical drop between the outlet of the first section and the inlet of the coin changer.

Title: Electronic apparatus
Inventor: HANAOKA SHUNSUKE
IPC: H04N5/64
Filed: 1995-11-24
Abstract: An electronic apparatus has a demodulating section and a strap antenna having a conductor in its inside. Radio waves received by the strap antenna are demodulated by the demodulating section. A receiving-sensitivity adjustment member having at least one through hole for passing the strap antenna in it is slidably placed on the strap antenna. Since a magnetic substance built in the receiving-sensitivity adjustment member changes the electric field generated in the conductor of the strap antenna, receiving sensitivity can be adjusted to the most appropriate state. With an insulator member placed on the strap antenna, a loop antenna can be used as a monopole antenna. When the strap antenna is made detachable, another antenna can be used depending on the use condition.

Title: Object-oriented programming environment that provides object encapsulation via encryption
Inventor: VOLDAL ERIK EDWARD
IPC: G06F12/14
Filed: 1997-02-05
Abstract: This invention relates in general to object-oriented encapsulated enforcement mechanisms. In particular, a hardware independent object encapsulation enforcement mechanism is disclosed herein. The object encapsulation enforcement mechanism of the present invention uses encryption technology to ensure that data controlled by an object is accessed solely through use of the object's method programs. When an object is instantiated, the virtual address used to refer to the object is encrypted before it is returned to the instantiating application program. When access to a previously instantiated object is requested, the object encapsulation enforcement mechanism decrypts the presented object address and passes the address to the identified method program, thereby ensuring that only object method programs have access to data controlled by the object.
