Various methods and systems for operating an internal combustion engine are provided. In one embodiment, an example method for operating an internal combustion engine includes, under a first condition, charging a compressed air storage vessel via a compressor. The method further includes, under a second condition, directly injecting compressed air from the storage vessel to a cylinder of the engine to enhance fuel combustion.

A fuel control system for controlling the supply of liquefied petroleum gas (LPG) to injectors of a fuel supply system during a cold start is provided. The fuel control system includes a LPG pressure regulator and a cold-start fuel control valve for throttling fuel to the injectors when the pressure of the LPG is below a nominal set point pressure of the pressure regulator. The cold-start fuel control valve may be in parallel or series with a fuel lock-off valve. The system is configured to supply limited discrete amounts of LPG to the injectors when the pressure of the LPG is below the nominal set point pressure to allow the LPG to vaporize prior to being injected, by the injector, into an engine. Operation of the cold-start fuel control valve during non-cold starts and normal operation are also provided.

An automatically-opening infant mat that is movable between an open position and a closed position includes a water-resistant flexible material sized to have an infant, at least from the infant's head to the infant's buttocks, placed on the material while the mat is in the open position, a cushion coupled to the material to be disposed under a portion of the infant's body while the mat is in the open position and the infant is placed on the material, and a resilient bias member coupled to the material and configured to bias the material to an open position and to be reversibly moved to a closed position.

The invention discloses a method for wireless terminal dynamically switching window in a wireless LAN environment. The wireless LAN comprises several access points and stations which establish wireless communication connections with the access points. The stations can switch the current access window by scanning. The method characterizes in that including following steps: giving the switching window an initial value through the stations; the stations judge if there is another access point of which the signal quality is greater than that of the current access window through scanning wireless channels; if so, further judge if the stations are in a frequently handoff status, if so, the handoff judging result is not allowed to switch window; if not, the handoff judging result is allowed to switch window. The present invention can adaptively adjust the stations' switch windows according to the stations' handoff status and frequently handoff status. On one hand, the invention avoids the occurring of frequently handoff by changing the handoff conditions of the stations, increasing the access efficiency of the stations which is in the handoff status and in a wireless LAN environment, while maintaining the sensitivity of the stations which is in the handoff status, ensuring the quality of the wireless links between the stations and the access points.

A flushing device (20) comprising an inner sleeve (21), axially slidable relative to an outer sleeve (23). The inner (21) and outer (23) sleeves cooperate to define an inner passage (32) for the flow of a fluid, and are permanently coupled such that there is substantially no rotational movement between the two sleeves. The inner passage (32) has an inlet (22b) and an outlet (22a). The outer sleeve (23) has a plurality of flushing outlets (33) which, when the flushing device (20) is in an open condition allow fluid to be diverted from the inner passage (32). The flushing device (20) also comprises an indexing mechanism (80) which indexes between a first position, wherein the plurality of flushing outlets (33) are blocked from the internal passage (32) such that the flushing device (20) is in a closed condition, to a second position, wherein the plurality of flushing outlets (33) register with the internal passage (32) such that the flushing device (20) is in the open condition. When fluid flows through the flushing device (20), the flushing device (20) is configured such that it remains in the selected open or closed condition regardless of the forces acting thereupon.

Embodiments of a friction drive system include a battery, a drive motor, a control unit, and a speed wheel. When the friction drive system is mounted on a wheeled vehicle, the speed wheel provides an accurate measurement of the vehicle speed by maintaining contact with a tire of the vehicle. An automatic traction control system, which may be part of the control unit, compares the speed of the speed wheel with the speed of the drive motor to determine whether slippage is occurring. If slippage is detected, then embodiments of an automatic traction control system automatically increase an amount of normal force between a contact surface on the drive motor and the tire, by advancing a position of the drive motor relative to a fixed mounting point. If no slippage is detected, then embodiments of an automatic traction control system automatically reduce the amount of normal force, by retracting a position of the drive r elative to a fixed mounting point. In embodiments of a friction drive system, the relative position of the drive motor may be controlled by powering a worm gear motor attached to a worm gear in response to commands from the control unit.

It is disclosed a method for re-distributing subscriber sessions originated from one or more access nodes of a communication network to a number of service nodes of the communication network. The method comprises: monitoring at least one performance parameter of the service nodes; comparing a value of the at least one performance parameter with a threshold; and, in case the value exceeds the threshold at a given service node, determining a number of subscriber sessions to be moved from the given service node; selecting at least one further service node to re-establish the number of subscriber sessions; and re-configuring the communication network to move the number of subscriber sessions from the given service node to the at least one further service node.

A power train for use in motor vehicles has a friction clutch including a housing which rotates with the output shaft of the engine and a clutch disc which transmits torque to the input shaft of a change-speed transmission in the engaged condition of the clutch. The clutch can be engaged and / or disengaged by one or more slave cylinders which is or are rotatably mounted on and is or are being held against axial movement relative to the clutch housing. At least one release bearing can be installed between the piston(s) of the slave cylinder(s) and the diaphragm spring of the friction clutch, and a second bearing is or can be installed between the slave cylinder housing(s) and the clutch housing.

The present invention relates generally to a method for automatically adjusting the interval of time between defrost cycles in a heat pump system. The method includes tracking the duration of the previous defrost cycle or cycles, and dynamically adjusting the length of time before initiating the next defrost cycle.

A fluid control system for delivery of a liquid includes a pneumatic drive that incorporates a linear actuator to effect known volume changes in a gas reservoir. The gas reservoir is in fluid communication with a gas-side reservoir that is separated from a fluid-side reservoir by a flexible membrane. Movement of the linear actuator effects positive or negative volume differences on the gas in the gas-side reservoir, resulting in a decrease or increase in pressure of the gas that is transmitted to the fluid-side reservoir to draw fluid, primarily liquid, in from a source or deliver liquid out to a sink. In another aspect, a mechanism is provided for the detection and elimination of air bubbles in the fluid path.
