Abstract: Mechanically attached connections for conduits may include a conduit gripping member and first and second connection members. The first and second connection members may be, for example, a nut member and a body member where the connection members cause axial movement of the conduit gripping member to grip and seal the conduit when the assembly is pulled-up. The mechanically attached connection may include a sensing function for detecting or sensing a condition or characteristic of at least one of the following: the mechanically attached connection, one or more of the connection members, the fluid contained by the mechanically attached connection, or a combination thereof. The sensing function may be, for example, a sensor that is integrated with at least one of the nut member and the body member.

Abstract: A compressor or fan is controlled to avoid stall, surge or flutter. The control system includes a look-up table from which is retrieved a margin-adjusted limiting value of a control parameter of the compressor, using inputs representing inlet guide vane angle (IGV), non-dimensional speed of the compressor (N/R?T), vehicle Mach number (Mn) and inlet geometry (IG). A variable stall, surge or flutter safety margin about a nominal limiting value of a control parameter is pre-established to reflect threats to the working, stall, flutter and surge lines, for example as a result of measurement inaccuracies, and from this the margin-adjusted limiting value is derived. An actual value of the control parameter is determined in real time, and the actual value is compared with the margin-adjusted limiting value. An output signal indicating stall, surge or flutter risk is generated if the actual value falls within the stall, surge or flutter safety margin.

Abstract: Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member (34), a drive member (36), and a seal member (48), the drive member (36) causing axial movement of the conduit gripping member (34) to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member (36) causing the seal member (48) to form a zero clearance seal at a location that is axially spaced from the conduit gripping member (34). The zero clearance seal may comprise a face seal arrangement including a gasket (48), and the conduit gripping member (34) may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include an optional sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both.

Abstract: A charging and discharging strategy for a rechargeable battery pack is disclosed. The strategy involves monitoring and learning the battery pack's condition (a cycle life parameter) in terms of its progression through its life cycle. The life cycle parameter may be determined as a function of both time (i.e., the battery pack's age) as well as the number of discharge/recharge cycles. The strategy intentionally under-utilizes the battery during the initial stages of its life, based on the cycle life parameter, by charging it to a first level less then the maximum state of charge. This approach reduces charge voltages, reducing stress on the battery's active materials, thereby increasing its life.

Abstract: A rechargeable multiple cell battery pack has an application associated therewith that draws power from the battery pack. While the battery pack is in operation, voltage, current, state-of-charge (SOC), and impedance data are collected on a per-cell basis and an algorithm is performed to determine a state-of-charge for each individual cell of the battery pack consistent with predetermined criteria. The individual cells are charged to the respective, determined state-of-charge (SOC) levels.

Abstract: A method and apparatus of the present invention are designed to equalize cell-to-cell imbalances in a multi-cell lithium battery system. A time-to-balance parameter is calculated for each cell at the beginning of charge, and balancing occurs for each cell having a positive time-to-balance at the beginning of charge. Alternatively, the time-to-balance parameter is calculated during operation of the battery system and equalization of the cells occur in-sit based on the time-to-balance values.

Abstract: An energy system is formed of a plurality of battery cells, and has an application associated therewith that draws power from the energy system, thereby creating a load profile that is presented to the energy system. As the application is being used, voltage and current measurements are taken at a predetermined rate, and stored in a history table to create a series of time-based measurements. The measurements stored in the history table are then processed to produce an energy spectra and a power spectra corresponding to the load profile presented to the energy system by the application. A charging strategy in accordance with this energy spectra and power spectra is then defined and used to charge the energy system appropriately.

Abstract: A charging strategy for a rechargeable battery pack is disclosed. The battery pack is used in an application that includes a dynamoelectric machine that may operate as a motor, drawing power from the battery pack, or as a generator, delivering regenerative energy to the battery pack. The strategy monitors the nature, intensity, duration and frequency, among other things, associated with encountered episodes of regenerative energy from the dynamoelectric machine, and adjusts subsequent recharging processes to allow a calculated amount of headroom to accommodate regenerative energy inputs in the future, which may be assumed to be equal in nature, intensity, duration and frequency to what has already been observed. Overcharging is reduced or eliminated, while maximizing the amount of charge on the battery pack, and thus duration of use.
