An apparatus is disclosed comprising a suite of sensors for measuring instant static and dynamic pressure and the speed and acceleration of a vehicle, such as a bicycle. A microprocessor receives data from the sensors and calculates power expended by the rider or other power source by finding the total of all forces impinging upon the vehicle and rider, thereafter multiplying by the speed of the ground vehicle. In some embodiments accuracy is improved by calibration techniques, user input of data, or temperature compensation of certain factors. Other data, such as wind speed, distance traveled, altitude, or surface grade may be presented to the user. In one embodiment data is stored for later analysis.

Method for measuring total force in opposition to a moving vehicle

Bicycle computer enclosure

A system of intelligent appliances coupled by common household power lines or wireless links. One or more of the appliances serves as a system controller and may include a further communications interface for coupling to an external communications network, such as the telephone network. The system can thus be accessed and controlled remotely. The system can also communicate with and obtain information from remote sources such as Internet-based facilities.

Food preparation system

Processor-controlled mixture with weight sensors

A system of intelligent appliances coupled by common household power lines or wireless links. In particular, the system includes one of more of a kitchen console, a breadmaker, a slow cooker, and a rice cooker/steamer. One or more of the appliances serves as a system controller and may include a further communications interface for coupling to an external communications network, such as the telephone network. The system can thus be accessed and controlled remotely. The system can also communicate with and obtain information from remote sources such as Internet-based facilities.

Appliance communication and control system and appliances for use in same

A system for communicating digital information over wires having a great deal of harmonic distortion, attenuation and noise, such as a power line, employs a transmitter which generates a signal representing a symbol of data. Some form of signal modulation such as Differential Phase Shift Keying (DPSK) or Frequency Shift Keying (FSK) is used to encode the data. The transmitter will continuously transmit or retransmit each data symbol until an acknowledgment is received from a receiving device. At the receiving device, the received signal is sampled and multiple repetitions of the same symbol are averaged to reduce noise. The averaged samples are then analyzed to demodulate the data. Both transmitting and receiving devices are clocked at the same frequency which is derived in both from the fundamental power line frequency. As such, the generation and detection of the data signals is coherent, making it possible to average out the effect of noise over multiple frames thereby ensuring communication even over highly noisy transmission media.
