A method of configuring a hand-held instrument (10) for determining the concentration of a medically significant component of a body fluid or a control comprises providing a configuring computer (14) having a first port (18) for transmitting instructions and data for configuring the instrument (10), providing on the instrument (10) a second port (17) for receiving the instructions and data from the configuring computer (14), coupling the first port (18) to the second port (17), transmitting instructions and data to configure the instrument (10) from the first port (18), receiving the instructions and data at the second port (17), and configuring the instrument (10) according to the instructions and data transmitted from the first port (10) and received at the second port (17).

An instrument (20) has a well (28a-b) for receiving a dry cell (75), an opening (78) through which a first connector (74) is exposed to the well (28a-b), and a boss (76) adjacent the opening (78). The boss (76) precludes the wrong terminal of the dry cell (75) from engaging the first connector (74) when the dry cell (75) is inserted into the well (28a-b) in incorrect orientation. A second connector (80) includes a base (81), a first leg (82) resiliently connected to and extending away from the base portion, a second leg (84) resiliently connected to and extending away from the first leg (82), and a third leg (86) resiliently connected to and extending away from the second leg (84) and toward the first leg (82). A display (42) for the instrument (20) has a lens (90) having a substantially transparent substrate with a polyurethane coating. The instrument housing has first and second portions. At least one locator pin (30) extends from one (24) of the housing portions and at least one complementary socket (32) extends from the other (22) of the housing portions for receiving the pin (30) to maintain the first (22) and second (24) portions in assembled orientation.

A vehicle mounted energy generator and storage system includes: a screened air inlet facing a front of the vehicle through which air enters when the vehicle is moving forward; a pneumatic barrel impeller assembly including one or more integral impeller air vanes positioned such that air flowing through the air inlet applies positive pressure to the one or more impeller air vanes to turn the pneumatic barrel impeller assembly and drive one or more generator/transmission assemblies; one or more batteries receiving energy generated by the pneumatic barrel impeller assembly; and an evacuation blower applying negative pressure to the rear of the impeller air vanes by evacuating air through one or more screened outlets not facing the front of the vehicle.

A power assisted combination shear used for forming structural louvers in the crimped seam of structural steel decking comprises a frame supporting a pair of jaws which are opened and closed by means of an operator-controlled pneumatic cylinder. One jaw terminates in a blade and the other jaw has a corresponding die member. The blade and die have undercut reliefs in the root portions, which permit the louver to be formed without breaking through to the edge of the seam. The louver comprises a sheared portion in the form of a bowed tab bridging a corresponding window formed in the seam by the shearing of the tab. The interference between the louver and window provides a substantial increase in the lateral resistance (shear strength) of the crimped seam, thereby obviating the need to additionally weld or screw the seam to provide the necessary shear strength for even the highest stress applications.

An instrument for determining a characteristic of a biological fluid or a control includes a radiation-reflective surface, a first source for irradiating the surface, and a first detector for detecting radiation reflected from the surface. A cuvette for use with the instrument holds a sample of the biological fluid or control the characteristic of which is to be determined. The cuvette has two opposed walls substantially transparent to the source radiation and reflected radiation. The first source and first detector are disposed adjacent a first one of said two opposed walls and the radiation reflective surface is disposed adjacent a second of said two opposed walls.

In combination, an instrument for determining a characteristic of a biological fluid or a control, and a cuvette for holding a sample of the biological fluid or control, the characteristic of which is to be determined. The instrument comprises a radiation-reflective surface, a first source for irradiating the surface, and a first detector for detecting radiation reflected from the surface. The cuvette has two opposed walls substantially transparent to the source radiation and reflected radiation. The first source and first detector are disposed adjacent a first one of the two opposed walls. The radiation reflective surface is disposed adjacent a second of the two opposed walls. A second source is provided for irradiating the surface. The first detector detects radiation from the second source reflected from the surface. The second source is positioned to transmit radiation through the two opposed walls for reflection by the surface and transmission back through the two opposed walls to the first detector to indicate whether a sample has reached a first point in the cuvette.

An instrument monitors the coangulation of coagulable fluid blood, blood fraction or a control by combining the coagulable fluid with particles which are affected by a magnetic field so that the particles become suspended relatively freely in the fluid. A time-varying magnetic field causes the particles to be reoriented as the magnetic field varies. The reorientation changes as the fluid coagulates owing to the fluid's changing viscosity. An electromagnet creates the time-varying magnetic field. The electromagnet includes a core comprising a first leg an electrically conductive coil for creating a time-varying magnetic flux in the core, and a return for the time-varying magnetic flux. The first leg and the flux return together comprise a generally H-shaped core of ferromagnetic material. A bobbin is provided on the first leg and the electrically conductive coil is wound on the bobbin.
