  • Patent number: 8556775
    Abstract: A system and method for regulating torque transmitted via a torque converter can include providing a lock up clutch between a crankshaft and transmission of a vehicle. A position sensor can output data indicative of at least one of an engaged position of the lock-up clutch, a transitional position of the lock-up clutch, and a disengaged position of the lock-up clutch. An engine speed sensor can output data indicative of rotational speed of the crankshaft. A controller can be placed in electrical communication with the engine speed sensor and the position sensor and configured to determine when actuation of the lock-up clutch is desired. The controller can be configured to determine a torque reduction target based on certain variables, for example, engine acceleration. The controller can then signal the engine to output torque substantially equal to the torque reduction target when conditions exist that warrant torque reduction.

  • Publication number: 20120080467
    Abstract: A transportable barbeque support and combination allows for safe transport and easy sliding access to a full size barbeque, fuel tanks, and coolers. A base is mounted securely to the truck bed, trailer, or RV and a sliding frame is movable thereon for movement between a transport position and an operating position. The barbeque is fit to a distal end of the sling frame and storage including fuel tanks at an inside or proximal end. A heat shield can be positioned between the barbeque and storage. A locking mechanism between the sliding frame and base ensures the barbeque remains securely in either the transport or operative positions.

  • Publication number: 20100324440
    Abstract: An approach is provided for real time stimulus triggered by brain state and includes receiving data that indicates a brain state and a set of one or more stimuli associated with the brain state. Onset of an instance of the brain state is detected in a subject. In response to detecting onset of the instance, application to the subject of a stimulus of the set is initiated before the instance ends. In some embodiments, the brain state is determined based on a range of values for a function of brain signal data, wherein the range of values is associated with desired performance in response to an associated stimulus. The approach can enhance performance, enhance learning or enhance the probing of impact of that state on perception, action or cognition.

  • Patent number: 6937148
    Abstract: A multi-station RF thermometer and alarm system measures temperatures and/or percent relative humidity at remote locations by RF weather stations, and displays received temperature and/or other weather data telemetry on a multi-station base station that provides out-of-bounds alarm signal indications whenever temperatures are outside of user-selectable minimum and maximum values. Randomized transmission times in one embodiment and two-phase unique transmission schedules in another lessen the possibility of on-going collisions between two or more transmitters contending for the base station at the same time. Redundant data transmission lessens the possibility of environmental noise interference.

  • Patent number: 6246322
    Abstract: An electronic key or other missing object locator device is responsive to the impulse characteristics of received sounds to distinguish expected impulse-like triggering sounds such as humanly produced hand claps from other impulse-like sounds such as speech or music or non-impulse-like sounds. Errors may be counted whenever the received sounds do not correspond to the expected characteristics of the expected impulse-like triggering sounds. Whenever the expected number of triggering sounds having the expected impulse characteristics have been discriminated and detected, an audible alert is sounded, provided that the errors are not too many. The device of the invention is thereby able to distinguish expected hand claps (or other humanly produced sounds) from non-intended music, speech or other impulse-like or non-impulse-like triggering sounds, rendering it operable even in noisy environments. False alarms from mechanical wave energy are prevented.

  • Patent number: 6046674
    Abstract: A multi-station RF thermometer and alarm system measures temperatures at remote locations by RF thermometers, and displays received temperature telemetry on a multi-station base station that provides out-of-bounds alarm signal indications whenever temperatures are outside of user-selectable minimum and maximum values. Randomized transmission times lessen the possibility of on-going collisions between two or more transmitters contending for the base station at the same time. Redundant data transmission lessens the possibility of environmental noise interference. The redundant data transmitted at random times includes a unique channel ID code, house-keeping data, the current temperature and/or time-to-next-transmission data. The temperature sensing transmitters operate at a low duty cycle with low peak current consumption resulting in long battery life. The multi-station base station may be AC- or battery-powered.
