  • Image unlocking jewelry device
    Patent number: 7040778
    Abstract: An image locking jewelry device designed to hide a customized image from view until the wearer reveals the image. The image unlocking jewelry device includes a lens mated to a casing and housing a liquid crystal display; a light emitting diode; circuitry placed inside the casing and capable of sending signals to the liquid crystal display and the light emitting diode; and an image positioned between the lens and the circuitry. Voltage is sent from the circuitry to the liquid crystal display and the light emitting diode in order to reveal the image held underneath the lens.

  • Image unlocking jewelry device
    Patent number: 6715911
    Abstract: An image locking jewelry device designed to hide a customized image from view until the wearer reveals the image. The image unlocking jewelry device collectively including a lens mated to a casing and housing a liquid crystal display; circuitry placed inside the casing and capable of sending signals to the liquid crystal display; and an image positioned between the lens and said circuitry. Voltage is sent from the circuitry to the liquid crystal display in order to reveal the image held underneath the lens. The unlocking process can either be electromechanical or electromagnetic. If electromechanical, a series of buttons positioned around the device can be pressed in a particular sequence in order to send a voltage that uncovers the image held within the jewelry device itself or held inside a companion device. Otherwise, a magnetic resonance frequency can be sensed from the companion device, sending a signal to unlock the wearer's device.
