  • Publication number: 20200179748
    Abstract: A seated treadmill has a structure with a front portion and a rear portion. A front roller is rotatably mounted on the front portion of the structure, a rear roller is rotatably mounted on the rear portion of the structure, and a belt circumscribes the front and rear rollers. The front and rear rollers are much closer together than prior art treadmills, typically about 10-30 inches. The treadmill may further include a remote control for controlling operation of the treadmill, and a shutoff switch in the event that too much force is placed upon the treadmill, such as if the user attempts to stand on the treadmill.

  • Patent number: 8288966
    Abstract: A colored light generating element can be configured to, while in an active state, pulse between an off state and an on state. A substantially constant offset voltage or current can be applied to the colored light generating element during a predetermined time interval when the light generating element is in the off state so as to cause the colored light generating element to emit, during the off state, some amount of light greater than a minimum amount of light that the light generating element is capable of generating while part of an active system. In some implementations, two or more offset voltages or currents can be applied. Implementations may include a preprocessor configured to receive an image signal and optimize color saturation of the image signal, such as by limiting and non-linearly increasing color saturation. Implementations may include multiple colored light generating elements.

  • Patent number: 8270055
    Abstract: Methods, systems, and apparatus for resetting a micro-mirror devices. In one aspect, a micro-mirror device includes a mirror plate tiltable about a hinge, two electrodes located on different sides of the hinge, a memory storing state data for the electrodes, and a state modifier operable to receive the state data for the electrodes from the memory and, during a reset of the mirror plate, change the state for at least one of the electrodes from the state specified by the state data stored in memory to a different state.

  • Publication number: 20090278870
    Abstract: A method for displaying a pixel on a display system using a series of digital pulses obtained by first determining a minimum pulse width (MPW) capable of displaying a pixel on the display system and then using a series of pulses for the display of the pixel, where at least some of the pulses have different pulse widths, and where at least one pulse has a width that is a non-integer multiple greater than 1 of the MPW. In this way, the number of unique intensity levels of the pixels of the displayed image can be increased and display resolution is improved. Even better resolution is obtained using two different, alternating series of digital pulses.

  • Publication number: 20030118193
    Abstract: A method and system for generating sound using a speaker having a transducer is disclosed. In a first aspect, the method and system comprise conditioning an input signal; and analyzing the conditioned signal in accordance with at least one transducer model. The method and system further includes providing a drive signal based upon the analysis and modulating a drive signal provided to the transducer. In a second aspect, a method and system for determining the positional BL factor of a transducer during sound transduction is disclosed. The method and system comprises continually at short time intervals measuring the change of the current to the transducer; measuring the back EMF of the transducer; and calculating the present positional BL factor from the change in EMF versus change in current. The new positional BL factor is then utilized directly in the transducer model.

  • Patent number: 5442669
    Abstract: A perishable good integrity indicator includes a first oscillator for outputting a first clock signal which does not substantially vary in response to temperature. A second oscillator outputs a second clock temperature which varies as a function of temperature. A counter counts the pulses of the second clock signal during a time period determined by the first clock and outputs a count value. A data table receives the count value, translates the count value into a time temperature value representing the relationship of time and temperature during the time period and outputs the time temperature value to an adder. The adder adds the time temperature values output by the data table over time and outputs a cumulative time temperature value corresponding to shelf life for a product.
