The inventive disclosure contained herein is generally directed to a class of medical bandages that in many embodiments are effective in the treatment of various types of tissue burns, whether be burns due to thermal burns, sun exposure, or rashes. Such products can include a plurality of specialized bandages and wraps that incorporate an extremely thin layer of thermally conductive metal (often aluminum) at the base of a substrate adapted to be in direct contact with a burn wound, while manufacturing the top side of the aluminum substrate to have a heat-dissipation-enhancing topography to help cool burns faster by enhancing thermal-convection properties. The bandage can also feature a thermochromic indicator for users to realize the thermal-cooling status of a burn to which a bandage has been applied.

A handheld computer comprises a display on the front side and a touch-sensitive surface on the back side. When a plurality of objects are displayed and the user selects one object with a first touch on the touch-sensitive surface in a position of the back-side surface that corresponds to the position of the object on the front-side display, a determination area is set for reselecting the object. After the user performs a second touch within the determination area, a given control process is performed on the object.
摘要:
An indicator arrangement for a regulator removably connectable to a facemask in a breathing apparatus, the indicator arrangement including: at least one release button comprising a body operationally engaged with at least one component of the regulator and configured to be actuated by a user to detach the regulator from the facemask, wherein at least a portion of the body is configured to facilitate transmission of light from at least one light source; and wherein the light is visible on or through at least one external surface of the body of the at least one release button. A regulator release button and breathing apparatus are also disclosed.

A respiration system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and a first data communication system, and a respiration facepiece including an interface to which the pressure regulator is removably attachable, at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of a wearer; an inspiration port in fluid connection with the pressure regulator interface and in fluid connection with the interior of the facepiece and at least one display within a volume of sealing engagement with the face of the user that is within the field of view of the user. The pressure regulator interface includes a second data communication system to receive data from the first data communication system to control the at least one display. A sealing attachment may, for example, be formed between the pressure regulator and the interface of the facepiece.
摘要:
A control method and apparatus for critical rotational speed avoidance in a compressor-expander set (165) in a gas refrigeration system. By varying an opening of an antisurge or recycle valve (300,305), a shaft power used by the compressor in the compressor-expander set may be varied, thereby varying the rotational speed (345) of the compressor-expander set to move it away from its critical speed zone. Additionally, a feedforward signal may be provided by a compressor-expander set control system to cause an antisurge valve for a recycle compressor to open upon a trip or shutdown of one compressor-expander set.
摘要:
An attaching structure for use in an attachable arrangement including at least one elongate strap and configured to be removably attached to at least a portion of a body of a user. The attaching structure includes: a frame having a first end and a second end, wherein the first end is configured for attachment of at least one strap of the attachable arrangement; and an adjustment mechanism is operational engagement with the frame, wherein at least a portion of the adjustment mechanism is configured to contact at least one strap of the attachable arrangement and permit adjustable movement thereof; and wherein the second end of the frame is elongated and configured to permit the user to grasp the second end of the frame and move it relative to the body of the user.
摘要:
A conductor rail assembly for use in transit rail transportation systems to transmit electrical power to rail cars comprising a first and second support sections preferably of aluminum to give the rail assembly its rail-shape and conductivity and a cap section preferably of stainless steel to provide a wear resistant surface to prevent damaging of the conductor rail by collector shoes that extend from rail cars and run on the conductor rail. The first support section has a rib and the second support section has a concavity. In the assembly, the rib of the first support member preferably is disposed within the concavity of the second support member, portions of both support members preferably are friction fit or compression fit within the cap and a friction stir weld preferably is disposed on the bottom of the assembly along a joint between the first and second support sections.
摘要:
A sensor includes a housing, at least two electrodes within the housing, an electrolyte providing ionic conductivity between the electrodes and a vent member including a first section including a portion extending through a passage in the housing. The vent member also includes at least one extending member connected to the first section that extends through at least a portion of an interior of the housing. The first section of the vent member is porous so that gas can diffuse from the interior of the housing to an exterior of the housing via the vent member.

A combustible gas sensor includes at least a first sensing element comprising a first conductive element having, for example, an average diameter less than 20μm in electrical connection with electronic circuitry. The combustible gas sensor further includes a first support element having a first anchored end, a second anchored end and an extending intermediate section between the first anchored end and the second anchored end, the extending intermediate section providing support for the first conductive element. Another combustible gas sensor includes a first sensing element and a second sensing element. The first sensing element includes a first catalyst support member having a volume less than a sphere having a diameter of 500μm. The second sensing element includes a second catalyst support member having a volume less than a sphere having a diameter of 500μm. The combustible gas sensor further includes electronic circuitry that is adapted to cycle between a first mode in which the first sensing element is operated in a higher power mode and the second sensing element is operated in a lower power mode and a second mode in which the second sensing element is operated in a higher power mode and the first sensing element is operated in a lower power mode.
