Patent number: 8639400Abstract: Altitude control of a toy flying vehicle intended for indoor hovering flight comprises providing a selected altitude level for the vehicle. A position control signal is transmitted from the vehicle towards a surface. A receiver in the vehicle receives the signal reflected from the surface. A level of the reflected signal by the receiver is determined, and a change of the reflected signal is an indicator of a change of altitude of the vehicle relative to the selected altitude level. The vehicle receiver communicates with the remote controller, and the remote controller can adjust and control speed and direction of the vehicle. Controlling the altitude can be by a stop control; an up and/or down control; and/or a high and/or low height sensitivity control, take-off/landing control; gesture mode control; left/right trim control; control between altitude control mode and manual control mode.Type: GrantFiled: March 15, 2013Date of Patent: January 28, 2014Assignee: Silverlit LimitedInventor: Kwok Leung Wong

Patent number: 8430709Abstract: A flying toy has a propeller rotated by the first motor mounted on the body. A propeller holder mounts the propeller. An end cap is located to the front of the propeller holder, and there is a snap joint between the holder and the end cap. The end cap is removable by disengagement of holder and end cap at the snap joint, and the propeller is releasable from the holder by a human hand and without a tool. When the toy crashes, the propeller is forced relatively free from the drive force rotating the holder and back towards the body and is trapped against separation from the toy.Type: GrantFiled: July 30, 2012Date of Patent: April 30, 2013Assignee: Silverlit LimitedInventor: Kwok Leung Wong

Patent number: 8371897Abstract: An interactive toy comprises a body having a non-reactive portion and a reactive portion. There is a CMOS image sensor with the body for capturing an image in the vicinity of the body. A microprocessor processes the captured image and generates instructions in response to the processed image. The instructions cause operation of the reactive portion of the body. The toy can be a doll including a plush, soft or hard plastic head and body; and the CMOS image sensor has a resolution of about or selectively less than 1M pixels.Type: GrantFiled: January 19, 2012Date of Patent: February 12, 2013Assignee: Silverlit LimitedInventor: Kwok Leung Wong

Patent number: 8357023Abstract: A helicopter includes a system to effect motion in a horizontal dimension thereby to direct the desired direction. The rotor blades are driven by a rotor shaft and which is hinge mounted on this rotor shaft, such that the angle between the plane of rotation of the main rotor and the rotor shaft may vary. A control for moving the angle of incidence of at least one blade of the rotor cyclically along at least part of a 360-degree rotation path around the rotor shaft. This causes a variation in a lift force of the blade along at least part of the rotations path. This causes the body to be urged in a relatively horizontal direction from a relative position of rest. The control includes an actuator for engaging with an assembly depending from the rotor, the inter-engagement of the actuator and assembly effecting a change in the angle of incidence of at least the one blade of the rotor. The system includes a rotor, preferably complemented with a stabilizer rotor.Type: GrantFiled: August 31, 2009Date of Patent: January 22, 2013Assignee: Silverlit LimitedInventors: Alexander Jozef Magdalena Van de Rostyne, Chi Pok Billy Wai

Patent number: 8337274Abstract: A toy car and a remote control regulate the speed of the car. A source of supplemental power selectively energizes the drive motor thereby to selectively permit the vehicle to move faster than the normal speed. A sensor measures the voltage to the vehicle motor. After stepping up the voltage to the drive motor, and detecting a drive motor current increase in excess of the capability of vehicle, the source of supplemental power is disabled. When a normal low voltage state is detected, the source of supplemental power in the vehicle is enabled whereby the motor supply voltage is permitted to increase above a normal low voltage state permitting more power to be provided to motor.Type: GrantFiled: October 31, 2011Date of Patent: December 25, 2012Assignee: Silverlit LimitedInventor: Kwok Leung Wong

Publication number: 20120028538Abstract: A handheld electrical charger for a toy vehicle provides a manual handle on the housing for generating kinetic energy. A dynamo within the housing and in mechanical communication with the handle generates electrical energy from the kinetic energy. A power takeoff transfers a portion of the kinetic energy or the electrical energy to a power inlet for a toy, and the toy is separable from the charger. The toy includes an electrical storage device to be charged by electrical output from the inlet. The toy is operable as a toy under its own recharged electrical power when the power take off and power inlet is disconnected. There can be a power storage for DC power in the housing and/or in the toy. A dock is provided for selectively creating an electrical coupling of the toy vehicle to transfer the electrical power and decoupling to allow the vehicle to operate independently of the charger.Type: ApplicationFiled: July 30, 2010Publication date: February 2, 2012Applicant: SILVERLIT LIMITEDInventor: Kwok Leung Wong
