In-theater interactive entertainment system. A game server generates video content in digital form and is displayed on a digital display in a theater. A telephony system is connected to the game server enabling a group of individual game participants in the theater to exchange data wirelessly with the game server so that the game participants can interact with video content on the display. It is preferred that at the display is a reflective screen illuminated by a digital projector.

In-theatre interactive entertainment system

A device for displaying messages includes a passive display unit having a display screen, a receiver that receives downloaded information and a processor for processing and storing the downloaded information and providing control to the passive display unit. The display system may include a computer which stores information and a transceiver which downloads and stores the information received from the computer. A method of transmitting and displaying information on the passive display unit is also provided.

Passive display unit and system and method of use

A system for and method of controlling the temperature of a flat workpiece such as a semiconductor wafer are disclosed. The workpiece is mounted on a workpiece chuck which is mounted over a base between the chuck and a host machine such as a wafer prober used to test integrated circuits on a wafer. The chuck includes an upper portion on which the workpiece is mounted. The temperature of the upper portion of the chuck is controlled to control the temperature of the workpiece. The temperature of the base is controlled to reduce the amount of heat flow between the chuck and the host machine. A power and control system includes a switching power supply which provides power to system components including heaters in the chuck used to heat the workpiece. A series of filters removes electrical noise generated by the switching power supply such that low-noise operation is realized.

A safe, rechargeable, battery-containing power pack having a housing, a battery compartment for batteries to supply DC power to a battery-operated device, a printed circuit board to provide for the recharging of the batteries employing AC household power, and an interlock plug to act as an interlock switch and pivotably movable between an AC use position extending outwardly from the housing to recharge the batteries and an AC non-use, DC power, battery-operating position within a recess in the housing.

Safe, rechargeable, battery-containing power pack and method

An apparatus for use with a telephone including, in one embodiment, a detector for detecting when the telephone is in an off-hook condition and disconnect circuit for eliminating the off-hook condition when the off-hook condition is caused by the telephone so that phone calls may be received by the line. An alarm responsive to the detector produces a warning of the off-hook condition if another phone on the line is off hook.

Telephone accessory

An electronic game that includes a main body that consists of four panels assembled to form a four-sided pyramid having four vertexes. Each vertex serves as a node for supporting a light which may illuminate a plurality of different colors. Digital circuitry defines a color state vector at each node by illuminating one or none of the colors. Control circuitry connected to the digital circuitry is used for altering the color state of at least one of the lights as the tetrahedron is rotated. In one game, the color of the node brought to the top position changes in the color change pattern established by the color state vector. A player rotates the tetrahedron in an effort to figure out the pattern of color changes. Once the pattern is deciphered, the player makes additional rotations to achieve an object of the game such as having each vertex of the tetrahedron lighted the same color.

Electronic puzzle

A battery operated portable hydromassage appliance including control circuitry which senses the voltage level of the battery. When the battery voltage is below a predetermined level, the control circuitry automatically shuts the unit off so that the battery may be recharged before irreversible damage to the battery occurs. Also included is a low frequency oscillator which in combination with the low battery detector applies a pulsing input to the motor to turn the pump motor on and off and accordingly create a pulsing effect at the hydromassage appliance output.

Electronic game apparatus is provided which is controlled by a person jogging in place to establish a simulated race between a jogger and a simulated competitive runner on the face of a display. The simulated figures give an indication of accumulated input pulses between the jogger and the set rate of the electronic controls.

Electronically controlled exercising machine

A conductive touch grid or plate incorporated in the handle portion of apparatus such as an appliance performs the on/off function of the appliance as well as sensing the impedance of the operator with respect to either the line or neutral side of an associated AC source. Whenever the sensed impedance indicates a potentially dangerous condition a switching element in series with the line conductor interrupts current flow to the appliance thereby protecting the operator.
