Comfort product

An improved comfort product that uses an airflow through a heat exchanger and into the comfort product to selectively heat or cool an occupant has a support layer contacting and supporting a channel layer. The channel layer has at least one channel with an opening to accept air. The channel layer contacts and supports an engineered distribution layer that has numerous small holes making it air permeable. The engineered distribution layer contacts and supports an air permeable comfort layer that is of such size and shape to support an occupant of the comfort product. The comfort product also has a heat exchanger assembly for supplying heated or cooled air to the opening in the channel. The heat exchanger assembly includes an air intake having an intake fan, an exhaust outlet and a heat exchanger for selectively heating or cooling air flowing through the heat exchanger resulting in selectively heated or cooled supply air and exhaust air. The intake fan forces air through the heat exchanger where some of the air is selectively heated or cooled to be supplied to the comfort product and some air is used as exhaust air (to remove the unwanted heat if the supplied air is cooled or to warm the exhaust side of the heat exchanger if the supply air is warmed.). The selectively heated or cooled supply air then moves through the channels in the channel layer and the exhaust air exits through the exhaust vent. The selectively heated or cooled supply air then moves through the engineered distribution layer where the numerous small holes diffuse the air and then the selectively heated or cooled air then moves through the comfort layer where the air is further diffused and where the selectively heated or cooled air can selectively heat or cool an occupant of the comfort product.

Method and device for detecting gases by absorption spectroscopy

A method and device for measuring a concentration of a preselected gas in a gas sample are disclosed. The device comprises a Herriott type multipass cell (10) having a center axle (74) and a housing (80A, 80B) surrounding and spaced from the axle to provide a tubular sample cavity (84). The gas sample is pumped through the sample cavity via apertures (154, 156) provided in opposed ends of the axle. A first mirror (44) and a second mirror (46) are supported at opposed ends of the axle. A light source, e.g. a laser or LED, is provided for emitting a light beam into the sample cavity via an entry aperture (30) in the first mirror, the light beam having a wave length at which the preselected gas strongly absorbs. The beam is reflected between the mirrors for a number of times before exiting the cell via an exit aperture (48) in the second mirror and impinging on a detector (52). The device further comprises a reference detector (32) for monitoring the intensity of the unattenuated light beam and a detector for detecting the intensity of light transmitted through the second mirror after a single pass through the cell. The light source is operatively connected to a heat control assembly having a heat sink and the gas sample is passed said heat sink to augment temperature control of the light source.

Three-dimensional rapid prototyping method and device based on pulse small hole droplet injection

The invention relates to a three-dimensional rapid prototyping method and device based on pulse small hole droplet injection and belongs to the technical field of three-dimensional rapid prototyping. The three-dimensional rapid prototyping method is characterized in that a heater is used for heating a crucible until the metals in the crucible are in the molten state, a positive differential pressure value is set between the interior of the crucible and a vacuum chamber, simultaneously a piezoelectric ceramic driver applies certain pulse signals to piezoelectric ceramics to lead the piezoelectric ceramics to drive a transmission bar to generate longitudinal infinitesimal displacement, the infinitesimal displacement acts on the metal melt at the bottom of the crucible, tiny droplets are injected from small holes arranged at the bottom of the crucible, one droplet can be formed at the position of the small holes once the piezoelectric ceramics move for one time, size data of the droplets are timely analyzed through a photograph system, further the optimum parameter is obtained through adjustment; and the droplets fall to a moving three-dimensional motion platform to be deposited, and accordingly needed metal parts are formed through depositing. The three-dimensional rapid prototyping method and device based on pulse small hole droplet injection have the advantages that the pulse small holes inject to generate the metal droplets with uniform and controllable sizes, prototyped products are fine and uniform in microstructure, the prototyping process is strong in controllability, and the formed parts are high in accuracy.
