Abstract: A hydrotherapy system uses a plurality of water sources, each of which produces water at a fixed temperature. The water from the fixed temperature sources can be mixed to form several mixed water streams, each with a predetermined temperature, by an array of computer-controlled on-off solenoid valves. Solenoid valves can also be used to apply the mixed water streams with different flow rates selectively to different body zones. The solenoids are controlled via sequences that can be created and maintained with an intuitive graphical user interface.

Abstract: A connection between a monitoring device and a remote user is accomplished securely over the Internet by using a communication channel with public/private key encryption to connect the two locations and by performing authentication of a user at the local monitoring device rather than at a device server at the remote location, thereby effectively removing the device server as vulnerable point for attack. In particular, when a remote user attempts to log in, via a web browser or interactive telephone system, the encrypted channel is established using the public/private key of the device and the device server proxies the log-in request to the monitored device. The device itself is then responsible for granting or denying access.

Abstract: An interactive system is disclosed that includes an infrared source assembly for illuminating an exposed interface surface that is exposed to a user with substantially uniform infrared illumination, a diffuser for diffusing infrared illumination, and an infrared detection system for capturing an infrared image of the exposed interface surface through the diffuser. The infrared detection system provides image data that is representative of infrared illumination intensity of the exposed interface surface.

Abstract: A continuous flow bathtub having at least two inlets on the head end of the tub, such that water enters the bathtub above a user's shoulders, flowing down over the bather's body and down to the water level in the bathtub, flowing out through an overflow trough at the foot end. This provides a luxurious experience of massage by clean, unused flowing water, without the need for expensive, complicated anti-siphon devices.

Abstract: In order to allow viewers to interact with a television broadcast, a central control establishes a virtual environment in which viewers participate with characters designed by them. Viewers can create a character with the aid of a computer and then submit the character to the television show on disk or transmit the character via a web site. In order to create characters, a user “preprograms” a character by setting certain parameters and characteristics. Thereafter, the character would operate autonomously. During the television broadcast, some of the characters submitted to the television show or web site can be selected for appearance on the show by any conventional means, such as by lottery, sequentially or based on the merits of characters submitted to the television show, etc. Characters may also be submitted before the show and selected based on a “virtual interview.

Abstract: A message generated by an originator participant is entered into a “bottle” that passes the message from participant to participant. The bottle may be a hand-held device that is capable of directly communicating with another such device. When the originator is located close enough to another participant who also has such a hand-held device, the devices communicate and the message is passed from the originator to the other participant. The bottle may be a hand-held device that is capable of communicating with a central base station, such as a pager or cell phone or a computer that communicates with the base station via the Internet. When the originator enters a message into the device, a program at the base station selects a participant from the list to receive the message and the message is sent to the other participant.

Abstract: In order to coordinate an interactive computer game with a television broadcast, a central control establishes a large virtual environment in which viewers participate with characters either controlled or designed by them. Each user can directly control or influence characters within a “active region” which encompasses part of the virtual environment that is much less than the total environment. The broadcast portion of the system also has an active region, at least a portion of which is shown on a broadcast television show. The locations of the active regions are controlled by the central control. In accordance with one embodiment, the central control moves the active regions of selected users so that these active regions coincide or overlap the broadcast active region. The selected users are then allowed to control characters that appear on the broadcast television show.

Abstract: A three dimensional physical toy that can be manipulated by a user is connected to a computer. Interchangeable accessory parts can be plugged into the toy via mechanisms which identify the accessory parts immediately when they are plugged into the toy body. A software program running in the computer displays a graphical character representation of the toy, including the accessory parts that have been plugged into the toy in a virtual environment on a monitor screen. The toy and the accessory parts interact dynamically with the software program so that the graphical character representation of the toy appears on the screen exactly as it physically appears to the user. The toy interacts with the virtual environment in each stage of construction an as each accessory part is added or removed. Therefore, as various accessory parts are inserted into, or removed from, the toy, the graphical character representation of the toy interacts with the virtual environment in different ways.

Abstract: A method and apparatus for generating three-dimensional, textured computer models from a series of video images of an object is disclosed. The invention operates by tracking a selected group of object features through a series of image frames and, based on changes in their relative positions, estimates parameters specifying camera focal length, translation and rotation, and the positions of the tracked features in the camera reference frame. After segmentation of the images into two-dimensional bounded regions that each correspond to a discrete surface component of the actual object, the texture contained in the various video frames is applied to these regions to produce a final three-dimensional model that is both geometrically and photometrically specified.
