A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

In an aspect, a toy assembly is provided, and includes a housing and a toy vehicle inside the housing. The housing has a movable housing portion, and at least one functional element that is movable and is separate from the movable housing portion. The toy vehicle has a drive wheel that, when driven in a first rotational direction causes the drive wheel to drive movement of the functional element so as to carry out a function without driving movement of the toy vehicle towards the movable housing portion, and when driven in a second rotational direction causes the drive wheel to drive the vehicle towards the movable housing portion.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

A pitching arrangement for a model helicopter includes a securing base, a plurality of servers supported by the securing base, a main connecting shaft linked to the servers, a supporting ring, a control device operatively provided between the servers and axially mounted to the main connecting shaft, and a plurality of connecting rods connecting the servers and the control device through the main connecting shaft, wherein the supporting ring is mounted on the main connecting shaft, wherein the connecting rods are connected to the supporting ring of the main connecting shaft.

A throwing or catching toy includes a generally elongated spheroidal body defined as having a longitudinal axis, where a length of the body along the longitudinal axis between a front end to a back end of the body is longer than an equatorial diameter. A support is attached to the body and extends beyond the back end of the body and does not extend beyond the front end of the body. A lift-generating wing is non-movably attached to the support. A push surface is disposed near the back end of the body, where the push surface is generally perpendicular to the longitudinal axis. A horizontal stabilizer is attached to the support and disposed behind the lift-generating wing. An impact transfer surface is attached directly to the support, where the impact transfer surface is disposed within the body and fixed between the front end of the body and the support.
