摘要:
A solenoid in which the coil is positioned inside a housing of magnetic material. The housing has a tubular projection forming a recess in the inside of the end wall along the axis of the coil, one end of the plunger projecting beyond the coil into the recess when the plunger is in the energized position. The portion of the plunger that extends into the recess is tapered to obtain a constant force-displacement characteristic for the full travel of the plunger.

In certain embodiments, a thermoelectric heat pump includes a heat transfer region having an array of thermoelectric modules, a waste channel in substantial thermal communication with a high temperature portion of the heat transfer region, and a main channel in substantial thermal communication with a low temperature portion of the heat transfer region. An enclosure wall provides a barrier between fluid in the waste channel and fluid in the main channel throughout the interior of the thermoelectric heat pump. In some embodiments, the waste fluid channel and the main fluid channel are positioned and shaped such that differences in temperature between fluids disposed near opposite sides of the enclosure wall are substantially decreased or minimized at corresponding positions along the channels.

A personal environment appliance and a vent for a personal environment appliance are provided. The appliance includes at least one thermoelectric module over at least one inlet port. The appliance further includes at least one main outlet port spaced from the at least one inlet port and at least one waste outlet port spaced from the at least one inlet port. The appliance further includes at least one filter between the at least one inlet port and the at least one thermoelectric module. The vent includes a plurality of first tubular conduits generally parallel to one another and each first tubular conduit having a ratio of the length divided by the width, The vent further includes a plurality of second tubular conduits generally parallel to one another and having a ratio of the length divided by the width. The plurality of second tubular conduits generally surrounds the plurality of first tubular conduits. The ratios of the second tubular conduits are sufficiently large such that air flow from the second tubular conduits is substantially laminar.
摘要:
A method and apparatus is disclosed for providing a passenger restraint actuation signal for use in an actuatable passenger restraint system in a vehicle is provided. The method comprises a sensor for providing a time varying electric signal proportional to vehicle deceleration. A crash energy is determined and compared against a predetermined limit. If the determined crash energy equals or exceeds the predetermined limit, a passenger restraint actuation signal is provided.
摘要:
A gas damped acceleration switch for use as a vehicle crash-sensing device. A mass is supported for movement along an axis against a spring, the mass actuating a switch only after moving a predetermined distance against the spring by an accelerating force. A gas damping system makes the device sensitive to the duration as well as the magnitude of the velocity change. Damping is provided by a plate movable with the mass having surfaces that are perpendicular to the axis of motion. The plate is normally pressed against a mating surface to exclude air. A seal is formed between the mating surfaces around the periphery so that a partial vacuum is formed as the mass moves the surfaces apart. When the surfaces move apart a predetermined distance, the seal is broken and the pressure equalizes. However, the moving plate still produces viscous damping as a function of velocity as it continues to be moved through the air by acceleration of the mass against the spring.

摘要:
A personal environment appliance is disclosed in which a person in a work area can individually control the ambient conditions of that persons localized work space environment. The control permits highly localized adjustment to suit individual preferences, thereby, reducing the impact of individual environmental preferences on the individuals. In addition to environment conditions, a variety of accessories may be provided such as beverage heaters and/or coolers.
摘要:
An audio navigation system incorporating an audio CD player for playing an audio format CD constituting a data storage medium for the navigation system. The CD may store a database containing map data and navigation information, software including an algorithm for selecting a desired route between a designated starting point and destination, and speech data for generating audible spoken statements through a sound system. The audio CD player may be part of a sound system and may also play audio CDs carrying musical selections.
