US Patent:

6860616, Mar 1, 2005

Filed:

Oct 4, 2002

Appl. No.:

10/264993

Inventors:

Sun Yu - Berkley MI, US
Andrew Tiefel - South Lyon MI, US
David Perrin - Troy MI, US

Assignee:

IQ Hong Kong, Ltd. - Tsuen Wan

International Classification:

B43K029/10

US Classification:

362118, 362 84, 362579, 362800

Abstract:

An ultraviolet light emitting diode flashlight is contained within a housing having a pen tip extending from the housing and an ink or dye reservoir in fluid communication with the pen tip. The ultraviolet light emitting diode flashlight within the housing emits light capable of inducing fluorescence in the ink or dye. A switch assembly completes an electrical circuit between a light emitting diode and a battery to activate the flashlight. A writing system package includes at least two of: a neon or pastel colored writing surface, a security pen having an ink or dye that fluoresces in the visible portion of the light spectrum upon exposure to ultraviolet light, and an ultraviolet light emitting diode flashlight.

Assignee:

Zen Design Group, LTD - Berkley MI

International Classification:

F21V021/084

US Classification:

362105, 362184, 362191, 362245, 362427

Abstract:

A headlamp includes a base having a front face defining a first imaginary plane along the front face and a first imaginary line orthogonal to the first plane. A light assembly is rotatably secured about the front face to the base. The light assembly includes a bezel having a rear surface defining a second imaginary plane along the rear surface and a second imaginary line orthogonal to the second plane so that the intersection of the first line and the second line defines a rotation angle that varies with the rotation of the light assembly relative to the base, thereby changing the attitude of the headlamp light assembly.

International Classification:

F21S006/00
A63H033/26

US Classification:

362124, 362103, 362191, 362155, 446485

Abstract:

A headlamp includes a housing securable to a human appendage. Within the housing a battery is located. Upon activation of a switch, the battery forms an electrical circuit with a light source located within the housing and directed to project a light beam therefrom. The housing is formed as an animate head having a mouth portion aperture defined by a hingeably secured jaw portion such that a light beam emanating from the light source projects through the aperture. The housing modifies the shape of the light beam and creates an inducement for a child-pedestrian to use the headlamp.

Appl. No.:

11/692233

Inventors:

Sun Yu - Berkley MI, US
David Perrin - Warren MI, US

International Classification:

A63F 3/28

US Classification:

446310, 446444

Abstract:

A toy is provided that has a dynamo for converting manual movement into an electrical charge for the dynamo located within a housing. A miniature vehicle is induced to locomote through receipt of the electrical charge. A dock is provided for selectively creating an electrical coupling of the vehicle to the dynamo to transfer the electrical charge and decoupling to allow the vehicle to locomote. A charge storage device and an electrical motor in the vehicle allow for prolonged vehicle locomotion separate from the charge transfer by the dynamo. A toy is also provided that has a dynamo for converting manual movement into an electrical charge, the dynamo located within a housing. The dynamo transfers an electrical charge to a wheeled miniature vehicle through an electrically conductive circuit about which the vehicle travels. Additional amusement functions of LED light output or speaker auditory output are optionally provided.
