  • Patent number: 7175092
    Abstract: The invention is a system and method for providing optimized accuracy and precision in analog-to-digital conversions of data. In an embodiment of the invention, an A/D converter is configured by setting two separately definable reference voltages that are controlled by a microprocessor. The A/D converter range is as wide as, or slightly greater than, a dynamic range of the analog signal to be converted. The microprocessor adjusts at least one reference voltage. The A/D converter receives analog signals from a sensor. The dynamic range of the signal from the sensor, or the sensor operating conditions, are used to define the reference voltages. The converted data is provided to a data processor at a rate controlled by a clocking signal. In a method according to the invention, the A/D converter is operated using the features described above. The accuracy and the precision of the converted data are thereby optimized.

  • Patent number: 7163052
    Abstract: In a parallel flow heat exchanger, which is susceptible to having a non-uniform distribution of a two-phase refrigerant flow to the individual channels, the resultant differences in the refrigerant flow therethrough are compensated and counter-balanced by a corresponding difference in the external heat transfer rate for the respective channels. In one embodiment, these differences are accomplished by variable characteristics of extended heat transfer surface elements such as fin type, fin density, fin geometry and difference in construction materials, and in another embodiment, by varying the airflow distribution over the cross-section area of the heat exchanger.

  • Patent number: 7163420
    Abstract: A compression connector body for connecting a hardline cable to an equipment port is formed in two members coupled to each other by a coupling nut. A port-side member houses a conductive pin and associated elements, while a cable-side member is attached to the cable via a compression fit. With this arrangement, when servicing the equipment, the cable-side member and attached cable are removed from the port-side member without affecting the connection between the cable and the cable-side member. The port-side member is then disconnected from the equipment port. After servicing the equipment, the port-side member is reconnected to the equipment port, after which the cable-side member is reconnected to the port-side member, thus alleviating the need to cut and prepare a new length of cable for connection to the equipment port.

  • Patent number: 7161785
    Abstract: A surge protection element for a conventional cable connector includes a printed circuit board preferably shaped as two concentric rings connected by two spokes. The outer ring is electrically connected to the grounded portion of the cable connector body. A printed circuit trace on one of the spokes is separated from a printed circuit trace on the inner ring by a spark gap. If a high voltage surge is carried by the coaxial cable transmission line, a spark is formed in the gap. As a consequence, the high voltage surge is transferred to the surge protection element which in turn conducts the electricity to the grounded body of the connector.

  • Patent number: 7152670
    Abstract: Existing plate-type heat exchangers typically include plates that are constructed of metal or paper, which are only capable of transferring a limited amount of moisture, if any, from one side of the plate to the other side. The present invention is a plate-type heat exchanger wherein the plates are constructed of ionomer membranes, such as sulfonated or carboxylated polymer membranes, which are capable of transferring a significant amount of moisture from one side of the membrane to the other side. Incorporating such ionomer membranes into a plate-type heat exchanger provides the heat exchanger with the ability to transfer a large percentage of the available latent heat in one air stream to the other air streams. The ionomer membrane plates are, therefore, more efficient at transferring latent heat than plates constructed of metal or paper.

  • Patent number: 7147162
    Abstract: A body portion of an optical reader has an elastomeric skirt surrounding the lateral edges thereof. The laterally spaced front edges of the skirt, which are on either side of a window through which the light is emitted and received along an optical axis, are angled rearwardly from a plane normal to the axis. The front edges extend downwardly and forwardly from a front edge of the bottom wall of a body, and also extend forwardly from a front edge of the top wall of the body. These features allow the lower ends of the front edges of the skirt to be placed on a surface near the target to act as a fulcrum in rotating the handle of the scanner to selectively place the reader in close proximity to the target, while at the same time allowing the operator to view the target.
