  • Patent number: 10112433
    Abstract: A security document and method of manufacturing the security document are disclosed. The security document includes a substrate including a laser reactive material and data. The security document also includes an optically variable tactile security feature formed in the laser reactive material, the optically variable tactile security feature including a non-tactile portion and a tactile portion. When viewed at a first viewing angle, the optically variable tactile security feature appears to be a first color, and at a second viewing angle different from the first viewing angle, the optically variable tactile security feature appears to be a second color.

  • Patent number: 9744791
    Abstract: A booklet processing mechanism is described that includes a spine guidance system that is configured to hold the area adjacent to the spine of an opened, multiple sheet booklet against a backing plate during processing on a page of the booklet, for example by a laser or during vision verification. The spine guidance system is configured so that it resides closely adjacent to the spine of the booklet, below the field of lasing by the laser or other processing operation, so that it does not interfere with the processing operation.

  • Patent number: 9346308
    Abstract: A booklet processing mechanism is described that includes a booklet guide and clamp system that is configured to act as the guide during entry and exit of the booklet into and from the mechanism, as well as clamp and hold the booklet in its proper position during a processing operation, for example by a laser or during vision verification. The booklet guide and clamp system is moveable between a first position for guiding an upper, free edge of an opened booklet and a second position where the upper, free edge is clamped against a backing plate. At the second, clamping position, the mechanism is out of the way so that it does not interfere with the processing operation. Because the guiding and clamping functions are combined into one mechanism, only one actuator and one sensor are needed for the guiding and clamping functions.

  • Patent number: 7441970
    Abstract: Identity document processing equipment with a mechanism designed to maintain tension in a ribbon used in a processing operation in the processing equipment. The tension maintaining mechanism is separate from the supply roll and the take-up roll for the ribbon, eliminating the need for clutches or brakes attached to the supply or take-up rolls to achieve tensioning. Since the tension maintaining mechanism is separate from the supply roll and the take-up roll, the inertia of the supply roll or the take-up roll does not affect the tension on the ribbon during use of the processing equipment.

  • Patent number: 5588763
    Abstract: A magnetically encoded plastic card production system is provided which includes a supply mechanism for supplying a series of blank plastic cards. An encoder is operatively coupled to the supply mechanism which encodes a magnetic strip on each card. A separating mechanism is operatively coupled following the encoder which has a roller surface for adhesively attracting loose particles from a surface of each card. A design placing mechanism is operatively coupled immediately following the separating mechanism which places a graphic design on each card. In this arrangement, the loose particles are separated from each card subsequent to encoding the magnetic strip on each card and prior to placing the graphic design on each card. A collecting mechanism is operatively coupled to the design placing mechanism which collects each card after each card has passed through the encoder, separating mechanism, and design placing mechanism. A method for producing magnetically encoded plastic cards is also provided.

The read/write head includes a plurality of inductively wound read/write gapped cores with a recessed core gap structure, and further includes a shield situated between the cores, such that a non-magnetic space is formed between the shield and each adjacent core. The width of the shield is no greater than the width of the non-magnetic spaces.

  • Patent number: 5453821
    Abstract: A method and apparatus for a two-pulse solenoid embossing system implementing an amplitude feedback circuit, i.e., current monitor (48), to provide precise amplitude and timing control over two current pulses (4, 5), and thereby provide precision control over the position and velocity of the embossing system's print elements (64a, 64b). To maintain the current amplitude during the second current pulse (5), the method and apparatus alternatively switches the power on and off to the solenoid coils (55) with a frequency such that a substantially constant current amplitude is maintained in the solenoid coils (55). The embossing system provides an improved solenoid body assembly (61) including a first stack of steel laminations (93), a center block (82) and a second stack of steel laminations (81). A plunger (62) is slidably connected to the solenoid body assembly (61) by shaft (63). Cavities (79) receive dowel pins (71) which are attached to plunger (62).

  • Patent number: 5320435
    Abstract: An apparatus for embossing sheet material by applying pressure to punch and die members positioned on both sides of the sheet material using force developed by one or more solenoids to force the punch and die members together to apply an imprinting force. In order to reduce the impact force, noise and wear on the mechanical parts, the solenoid may be energized in two separate steps, the first to move the punch and die members into contact with the surface of the card and the second to apply the embossing force to the punch and die members. Both rotary and linear solenoids may be used with differing coupling linkages in various embodiments of the embossing mechanism.

  • Patent number: 5266781
    Abstract: Standardized card processing modules are mechanically and electrically interconnected to form an application specific card personalization machine. A controller is coupled to a communication bus which permits the controller to download card data to the card processing modules and to upload status information from the card processing modules. Each one of the card processing modules performs a different encoding or personalization function under the control of a local processor.

  • Patent number: 5206489
    Abstract: An encoding apparatus (20) encodes or reads information on a magnetic stripe on a card (50). The encoding apparatus (20) advances the card (50) along a card transport path defined by a frame (24), side support members (42 and 44), and top guide member (46). The card (50) advances by reversible drive means (26) having a single drive roller (28). Encoding is accomplished by an encoding head (36) in communication with an encoder (22) coupled to an idler roller (34) for encoding by position.

  • Patent number: 5070781
    Abstract: An embossing apparatus (22) includes an embossing wheel (28) having a punch side (30) and a die side (32). The embossing wheel (28) has punch blocks (50) and die blocks (52) spaced around its periphery. A card (20) is carried to an embossing position by card transport (24) and aligned by a guide plate (36). The embossing is done by pushing the punch blocks (50) and die blocks (52) against the card (20) by a hammer (42, 42a) driven by a solenoid (38, 38a). Character return plates (46, 46a), located on the outer sides of the embossing wheel (28) engaging the inside of character blocks (35), spring the character blocks (35) and solenoid shaft (40, 40a) back to a home at rest position when the embossing stroke is completed. The solenoids (38, 38a) have bumpers (54, 54a) mounted thereon for controlling the motion of the shaft (40, 40 a).
