A presentation device includes a stimulation presentation unit that presents temperature stimulation at a predetermined temperature and a temperature control unit that sets the temperature of the stimulation presentation unit. The stimulation presentation unit has a size that causes a person to feel temperature stimulation when the stimulation presentation unit touches a first portion and the person not to feel the temperature stimulation when the stimulation presentation unit touches a second portion that is less perceptible than the first portion. The temperature control unit sets the temperature of the stimulation presentation unit so that the stimulation presentation unit presents pain due to temperature stimulation when the stimulation presentation unit touches the first portion and does not present the pain due to temperature stimulation even when the stimulation presentation unit touches the second portion.

A gaming system for enabling three-dimensional game play of remote-control craft controlled by a controller, each craft including a communication system with both radio frequency (RF) and infrared (IR) capabilities. The system can include a plurality of hovering remote-control flying craft each controlled by a handheld controller, and further may include at least one additional game accessory elements, such as a puck, a ground station or a gun. Each pairing of craft and controllers communicate via an RF protocol that transmits at least control communications between the controller and the craft based on pair identification information in an RF communication protocol. The craft and game-accessory elements also communicate via at least an IR protocol that communicates game-play information. Selectable pairs of craft and controllers may be assigned to different teams for playing multiplayer team games based on team identification information in the RF communication protocol.

A hovering remote-control flying craft having a molded frame assembly includes a plurality of arms extending from a center body with an electric motor and corresponding propeller on each arm. In various embodiments, the motor and propeller are mounted downward-facing at a distal portion of each arm with a motor cover over the motor. The center body can be formed of a two-piece molded structure that sandwiches a circuit board to provide structural support for the frame. The circuit board can include a plurality of tabs that facilitate mounting of wire connectors, and can also provide antennas and emitters for both IR and RF communications. In some embodiments, a removable safety ring protects the propellers from lateral contact.

A toy flowerpot with a movable toy flower includes a battery to power a mechanism in the toy flower. The flower includes the parts of a stem, sepal, petals and a front flower face around which the petals are mounted, at least one of which parts is a reactive part. A mechanism moves one or more parts of the flower; and includes an actuator with a magnet and electromagnetic coil with the flower. A signal receiver or sensor of changes causes at least one of movement of the flower parts. A microprocessor processes the signal or sensed change and generates instructions to change the operation of the electromagnetic coil in response to the signal or sensed change.

A holiday telephone system comprising: a smartphone; a holiday telephone in wireless communication with the smartphone; a holiday telephone app installed on the smartphone, where the app is configured to perform a method, the method comprising: creating a new message by inputting a message into the app via the smartphone; selecting an elf character to speak the message; scheduling the app to cause the holiday telephone to ring at predetermined date, and time; and playing the message as recited by the elf character when the telephone is answered. A non-transitory computer-readable medium includes a set of instructions stored thereon that when accessed by a processor enable the processor to perform a method of creating and scheduling a message to be delivered via a telephone, the method comprising: opening a messages page by default; determining whether the user selects to continue with messages; creating a new message if the user selects to continue with messages; determining whether the user selects to use most recently messaged child; choosing select elf, edit elf, or add new elf, if the user selects to use most recently messaged child; selecting an elf character, if the user chose select elf option; choosing enter message or quick message; entering message, if the user chose enter message option; choosing call now or schedule time for message; entering date and time for telephone message to be delivered to a telephone, if the user chose schedule time for message; displaying scheduled message; changing elf name, changing ringtone associated with elf, changing voice associated with elf, changing gender of elf, if the edit elf option was selected in the choosing select elf, edit elf, or add new elf query; returning to the selecting an elf character query; entering name of new elf; entering gender of new elf, selecting ringtone associated with new elf, selecting voice associated with new elf, if add new elf is selected at the choosing select elf, edit elf, or add new elf query.

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.
