  • Patent number: 6870579
    Abstract: System and method for learning the optimal channel change instruction recognition speed for an entertainment system. A memory stores information relating to: time increments between channel change signals; pulse width of each individual digit of a channel instruction; and the duration of time between each digit pulse signal. Based on the information stored in memory, a microprocessor constructs and sends channel change commands at a particular speed, progressively increasing the speed. When the speed at which channel change commands are sent exceeds the capability of the television receiver to recognize the channel change command, the microprocessor reduces the speed, as a function of the information stored in memory, until the television receiver can recognize the channel change command. The microprocessor stores in memory the fastest speed at which the television receiver can recognize the channel change command. Thereafter, the microprocessor uses the optimal speed to deliver channel change commands.

  • Patent number: 6871195
    Abstract: Method and system for computer assisted performance support include remote electronic monitoring and mentoring to provide for supervision, control and instruction of the worker while the worker performs directed tasks. Activity data representative of worker activities are collected at the work site and can be accessed by a supervisor located remote from the work site. The remote supervisor generates and transmits to the worker feedback based on the activity data. The remote supervisor can evaluate an activity trail of a worker's performance of directed tasks and development of skills through educational training to permit timely identification and correction of worker deficiencies. The ability of the remote supervisor to transmit feedback to the worker while the worker is performing directed tasks enhances rapid development of the worker's skills and workplace safety and productivity.

  • Patent number: 6867861
    Abstract: An apparatus for inspection of fluids, particularly dispersions and tints, having a fluid analysis cell with a cavity therein defining a fluid analysis chamber, fluid inlet and outlets extending from the cavity in opposite directions to enable fluid flow into and out of the analysis chamber, and a light transmitting probe and a light receiving probe extending within the cavity juxtaposed from each other across the flow path in spaced apart relation, with the probes being movable relative to each other, thus providing a fluid analysis chamber having an adjustable pathlength and allowing flow across and around the faces of the probes for pressure relief of the fluid, to provide accurate color measurements. The apparatus is particularly useful in the manufacture of dispersions and tints used in the manufacture of paints, so that the color of material being made can be accurately matched to a standard color in the wet state with confidence that the color will match in the dry state.

  • Patent number: 6864755
    Abstract: A modulated Class E transmitter is disclosed. In one embodiment of the invention, the modulated Class E oscillator achieves high coil currents (˜1A) and voltages (˜500V) with low power components by precisely timed injection of current when the oscillating current in the inductor passes through zero. A detector circuit is used to trigger the current injection at the appropriate instant regardless of changes in the resonant frequency of the system. Its phase can be adjusted to compensate for propagation delays in the drive circuitry, while amplitude modulation is accomplished by switching in additional reactive conductance to increase the current injected into the tank circuit.
