Abstract: A vibration-type cleaning device for contact lenses comprises an adaptor that is provided with a support part thereon for supporting a contact lens case and a base that is provided under the bottom of the adaptor. The base is connected with the adapter via a positioning element so that the base can be attached to or detached from the adaptor. The base is provided with a vibrator therein and the vibrator is connected with a power source. Consequently, the vibrator can be driven under the control of a user to vibrate the contact lens solution and the contact lenses in the contact lens case and the cleaning effect of the contact lenses in the contact lens solution can be enhanced through vibration.

Abstract: A necklace worn device for displaying short moving or static images in continuous loop based on the detection of the motion of wearers comprises a housing and a circuit board assembly. The housing is provided with a transparent window on one side thereof. The circuit board assembly provided detachably in the housing includes a pixelated display for displaying images, a non-volatile flash memory for storing images and other additional data, a microprocessor for processing the stored images and setting parameters, at least a motion detection switch activating the necklace worn device, a wireless transmitting and receiving unit for sending or receiving images, at least a rechargeable battery for power supply, and at least a control button for controlling the wireless transmitting and receiving unit and setting the parameters. The pixelated display is preferably an organic light emitting diode display and is provided under the transparent window of the housing.
