Abstract:
Способ дистанционного управления высотой полета радиоуправляемой модели летательного аппарата путем подачи с пульта управляющего сигнала на отклонение органов регулирования высоты в соответствии с заданной траекторией полета состоит в том, что задают предельный нижний уровень высоты полета, в процессе полета осуществляют измерение фактической высоты полета, по результатам измерений вычисляют текущее значение вертикальной составляющей скорости летательного аппарата и знак ее изменения, сравнивают фактическую измеренную высоту с заданным уровнем, и если фактическая высота оказывается меньше заданного уровня, осуществляют корректировку управляющего сигнала для компенсации отклонения высоты от заданного уровня посредством сигнала обратной связи по фактическому значению высоты и текущему значению вертикальной составляющей скорости, если знак изменения скорости отрицательный, или только по фактическому значению высоты, если знак изменения скорости положительный, и оставляют управляющий сигнал без изменения в случае, если фактическая высота превышает заданный уровень. Устройство для осуществления способа снабжено датчиком (19) измерения высоты и микропроцессором (16), имеющим средство программного обеспечения.
Abstract:
The inventive method for remotely controlling the flying altitude of a radio-controlled aircraft model by transmitting a signal for deflecting altitude adjusting controls according to an assigned flight path, consists in determining a lowest flying altitude level, in measuring the actual flying altitude during flight, in calculating the current value of the vertical component of the aircraft speed and the sign reversal thereof according to measurement results, in comparing the measured actual altitude with the assigned level, and if the actual altitude is less than the assigned level, in adjusting the control signal for compensating the altitude deviation from the assigned level by means of a feedback signal according to the actual altitude value and the current value of the speed vertical component, if the speed sign reversal is negative, or according to the actual altitude value only if the speed sign reversal is positive, and in leaving the control signal unaltered if the actual altitude is greater than the assigned level. The inventive device for carrying out said method comprises an altitude measuring sensor (19) and a microprocessor (16) provided with software providing means.
Abstract:
A play set comprises master and slave toy vehicles (50 and 70) and a stationary base unit (20). The master vehicle (50) includes a radio frequency (RF) receiver to be controlled by a manually operated RF remote control unit and an infrared (IR) transmitter configured to broadcast an IR tracking signal. The slave toy vehicle (70) includes a directional receiver to detect the source of the IR tracking signal and an on-board, self-directing control circuit coupled to the at least one directional receiver to control the slave toy vehicle (70) to chase the master toy vehicle. The base unit includes a platform with a game controller and one or more targets mounted so as to move when struck by the master toy vehicle. The game controller and one or both of the toy vehicles are configured for one way or two way wireless communications between the game controller and the toy vehicle(s). The game controller (12) is configured to initiate and control one or more modes of game play through the targets or communication with the toy vehicles.

Abstract:
Game playing apparatus for a plurality of players is described, comprising a target device (15a, 15b) having a detector for detecting an emission, emission means for directing an emission towards a detector, and means for administering a disincentive to one or more of said players in response to a signal from the detector. In one embodiment, the apparatus is a toy gun (50) and target game where successful shots by one player trigger an electric shock to the second player, via contacts (18a, 18b) on the gun or target. In another embodiment, the apparatus has remotely controlled toy vehicles (20), and successful shots fired from one vehicle to a second vehicle triggers an electric shock, via the control unit (30) of the second vehicle.
Abstract:
A toy vehicle (10) includes a housing (15); a chassis (20) having a rear end (24), a wing (150); a gear train cover (78), road wheels (54, 58) for running across support surface (S). The toy vehicle (10) further includes skid members (130,132), skid rails (144), a lift arm (62a) in retracted position with a second end (70), a strut (100).
Abstract:
A method and apparatus for gyroscopic steering of a vehicle comprising a flywheel tiltable on its axis of rotation where tilting of the axis causes rotation of the vehicle. When applied to a car, the gyroscopic assembly further includes a steering system with wheels mounted on a tilted pivotable axis wherein rotation of the chassis of the car in one direction causes the wheels on that side of the car to move together and the wheels on the opposite side of the car to move apart, thereby causing the car to turn. The apparatus of the present invention further provides commutative delivery of power to the motor spinning the flywheel, thus allowing the flywheel to be rotated 360° without interference from wires.
Abstract:
A method and apparatus by which an adult accompanying a child riding a mobile ride-on toy (120), can continuously determine if the child is free to fully operate the toy (120), The adult can force the toy (120) to slow down, or to stop or to otherwise control the ride-on toy (120) in order to protect the child's safety. The adult can gain control by operating a wireless remote-control unit (110). Furthermore, the adult can limit the distance between the ride-on toy and the adult, so that the child cannot drive too far away from the adult, i.e., the toy (120) stops as soon as the predetermined range limit is reached. The ride-on toy (120) can be used as long as it is under the control of the adult, but it automatically stops when the adult loses control over the ride-on toy (120).
Abstract:
A toy vehicle (10, 10') has a chassis (50), at least a first drive wheel (140) rotatably attached to the chassis and at least a first link (270) having a first end (271) pivotally coupled with the chassis. At least a first non-driven wheel (320) is operably coupled with the second opposing end of the first link. The first link has two operative positions: a first, fully-retracted operating configuration (20, 20') in which the first link is wrapped at least partially around the chassis crossing the drive wheel axis of rotation and a second, extended operating configuration (30, 30) in which the first link is pivoted away and extended from the chassis. A second link (210) can be pivotally coupled between and with the chassis and first link. Forces acting on the toy vehicle resulting from driving the first drive wheel can cause each link to pivot with respect to the chassis.
