Abstract: A scanner monitors a vehicle engine module's performance, such as, for example, a vehicle engine powertrain by creating and compiling performance data either in real time or based on a data post-processing schedule. A preventive maintenance or repair is suggested if the critical boundaries of a probable failure are reached.

Abstract: Containers are disclosed, as well as multilayer films used in such containers, which advantageously maintain a high seal strength even after being subjected to hot-fill conditions for sterilization. These microwavable/ovenable containers (10) and multilayer films are also beneficially self-venting upon exposure to microwave heating when the internal container pressure exceeds a threshold value. These self-venting containers are also automatically self-sealing after the self-venting feature has ruptured and the container has cooled to room temperature. The self-venting self-sealing nature of these containers arises from particular film and sealing characteristics, in which the seal width differs in defined, self-venting self-sealing seal regions (13A), relative to non-venting seal regions (13B) of a given peripheral seal.

Abstract: A pump module for use in a medical fluid dispensing system is provided that includes a pump body and first and second pump chambers formed in the pump body. The module further includes a pair of chamber inlets and chamber outlets formed in the pump body, each associated with one of the pump chambers. Each of the pump chambers further includes a first portion having a generally spherical segment shape and a second portion integral with the first portion and having a generally conical shape, with the first and second portions in fluid communication with the chamber inlet and the chamber outlet. The second, conically shaped portion converges to the chamber outlet.

Abstract: The present disclosure concerns flexible reclosable containers with a one way valve which provides a means to vent fluids, particularly air, from the interior of container when the repeatedly reclosable closure member, typically a zipper, is in a closed state. It also concerns a process for creating such a valve using a seal bar with voids to create a channel which passes behind the closure member. The valve which is disclosed involves a channel which comprises a central passageway which connects a port which communicates with the environment to a port which communicates with the interior of the package. Also disclosed is the concept of using this valve with a readily removable hermetic seal such that the port intended to communicate the environment initially communicates with the headspace between the reclosable closure member and the hermetic seal but does communicate with the environment when the hermetic seal is removed.

Abstract: Containers are disclosed, as well as multilayer films used in such containers, which advantageously maintain a high seal strength even after being subjected to retort conditions for sterilization. These retortable containers and multilayer films are also beneficially self-venting upon exposure to microwave heating, when the internal container pressure exceeds a threshold value. The self-venting nature of these containers arises from particular sealing characteristics, in which the seal width differs in defined, self-venting seal regions, relative to non-venting seal regions of a given peripheral seal. Particular structural features and geometries of the self-venting seal regions can be used to improve the location of venting and control of the vented gases.

Abstract: A pump is provided that includes a body made at least partially of an elastomeric material and an inlet port and an outlet port, with each port being coupled to the body. The pump further includes a flow passage formed in the body and extending between the inlet port and the outlet port, with at least a portion of the flow passage being normally closed and with the inlet port being fluidicly uncoupled with the outlet port when the pump is in a free-state condition. An actuating device is coupled to the body and is operable for sequentially deforming the body to create a cavity within the normally closed portion of the flow passage, the cavity being in fluid communication with the inlet port, thereby drawing a packet of fluid from the inlet port into the cavity and propagating the cavity and the packet of fluid contained therein toward the outlet port.

Abstract: A circuit element of a semiconductor device is provided. The circuit element has an electrical property and is formed by at least two like individual elements, each of said individual elements having an individual electrical property, the individual electrical property of each individual element including an error portion that is substantially statistically uncorrelated with regard to the other individual elements wherein the electrical property is a function of a summation of the individual electrical properties.

Abstract: According to a first embodiment of the present invention, reconfigurable resources within a reconfigurable test unit are configured to test or monitor a first function associated with a system under test. Following the completion of the testing or monitoring of the first function, the reconfigurable resources within the reconfigurable test unit are configured to test or monitor a second function associated with the system under test, wherein the second function may be substantially different than the first function. The method and apparatus so described allows for the testing of systems using a minimal amount of hardware and software resources within a reconfigurable test unit.

Abstract: A method of determining accurately and expeditiously the frequency of a coherent signal from an incoming electrical signal is disclosed. The method comprises the steps of: generating a time sequence of sampled data signals from the incoming electrical signal; detecting the coherent signal in the time sequence of sampled data signals and generating a frequency estimate thereof; and determining the frequency of the detected coherent signal based on a function of the frequency estimate and a time segment of sampled data signals associated with the coherent signal. A system for performing the same is also disclosed.
