20100237509IO CELL WITH MULTIPLE IO PORTS AND RELATED TECHNIQUES FOR LAYOUT AREA SAVING - An IO cell with multiple IO ports and related techniques are provided. The IO cell has a plurality of IO ports for transmitting signal of a same IO pin, and each IO port corresponds to a predetermined region for containing an IO pad, wherein at least one of the plural predetermined regions of the plural IO ports partially overlaps with active circuit layout region of the IO cell. In a chip, if a given IO cell has a predetermined region of an IO port overlapping an IO pad location of another adjacent IO cell, then a predetermined region of another IO port is selected for implementing an IO pad of the given IO cell, such that the IO cells can be arranged more compactly for chip layout area saving.09-23-2010

20100232079SMALL AREA IO CIRCUIT - A small area IO circuit is provided. The IO circuit has one or more parallel circuit unit(s) and an ESD protector set between a core circuit/pre-driver and an IO pad. Each circuit unit includes an off-chip driver and an output resistor, wherein the ESD protector protects ESD event occurred at the IO pad, and the resistor in each circuit unit acts as an ESD block circuit to block ESD current from corresponding off-chip driver. Therefore, transistors in each off-chip driver do not have to be restricted by strict ESD design rules, such that at least a transistor of the off-chip driver(s) is implemented in a single finger layout to lower equivalent capacitance of the off-chip driver(s), and layout areas of the off-chip driver(s) as well as the whole IO circuit can be reduced to achieve a small area IO circuit.09-16-2010

20080314922CAPACITY-ADJUSTABLE CARD DISPENSER - A capacity-adjustable card dispenser is disclosed to include a housing having an accommodation chamber for holding a stack of cards for dispensing, a plurality of expansion modules attachable to one another in a stack and attachable to the housing to expand the accommodation chamber for accommodating a greater number of cards, and male and female coupling devices respectively provided at the housing and the expansion modules for enabling the expansion modules to be detachably secured to one another in a stack and detachably secured to the housing.12-25-2008
20090218191CASH RECEIVER FOR CONSUMPTION SYSTEM - A cash receiver installed in an amusement machine for controlling the operation of the machine, including a face panel that has a coin slot, a coin-return slot and a vertical bill slot, a coin receiver unit that is affixed to the rear side of the face panel and has a coin entrance passage connected to the coin slot and a coin-return passage connected to the coin-return slot, and a bill receiver unit that is affixed to the rear side of the face panel and abutted against one side of the coin receiver unit and has a bill passage connected to the vertical bill slot. The client can insert a coin or a bill into the cash receiver to play the amusement machine.09-03-2009
20100078290AUTOMATIC VENDING MACHINE WITH USER'S IDENTITY RECOGNITION FUNCITON - An automatic vending machine for selling controlled commodities is disclosed to include a host, a card-swiping unit, a bill acceptor unit and a coin acceptor unit. The host has installed in the face panel thereof multiple display compartments for accommodating commodities to be sold, and a commodity take-out port and a coin-return outlet located on the face panel near the bottom side. The card-swiping unit has a card-swiping slot installed in the face panel of the host and an authenticity recognition module and an image sensor module for recognizing the user's identity. The bill acceptor unit has an insertion slot for the insertion of a card or bill, a transmission device for transferring each inserted card or bill, and a recognition device for recognizing the authenticity of each inserted card or bill. The coin acceptor unit has an induction coil module for detecting the authenticity and value of each inserted coin.04-01-2010
20100140863BILL POSITION ADJUSTMENT METHOD AND SYSTEM FOR BILL ACCEPTOR - A bill position adjustment method and system for bill acceptor is disclosed to include a body with an insertion slot and a bill passage, a transmission mechanism for transferring an inserted bill, a recognition device for recognizing the authenticity and value of an inserted bill, an entrance sensor and a stoppage sensor mounted in the bill passage for controlling the transmission mechanism to transfer the inserted bill into position for recognition, a bill passage adjustment mechanism for adjusting the width of the bill passage to correct the direction of an inserted bill into accurate alignment with the recognition device, and a bill sensor mounted in a sensor zone in the insertion slot for detecting the width of an inserted bill and controlling the bill passage adjustment mechanism to adjust the width of the bill passage subject to the detection result.06-10-2010
