Abstract: An engine assembly includes an engine block at least partially defining a combustion chamber and a crankcase volume. The engine block defines an opening in fluid communication with the crankcase volume. An air-oil separator is mounted to the engine block at the opening and is configured to separate oil from blowby gasses flowing from the crankcase volume through the air-oil separator. A method of venting an engine crankcase volume is also included.

Abstract: A control system for an engine includes a first lift control module and a second lift control module. The first lift control module increases lift of M valves of the engine to a predetermined valve lift during a period before disabling or re-enabling N valves of the engine. The second lift control module decreases the lift of the M valves to a desired valve lift during a period after enabling or re-enabling the N valves of the engine, wherein N and M are integers greater than or equal to one.

Abstract: Systems, methods, and computer program products for mitigating signal noise at a wireless smart device reader are disclosed. According to one aspect, the subject matter described herein includes a method (performed at a wireless smart device reader) that includes receiving a signal from a wireless smart device and checking for an error in a portion of the signal. In response to detecting the error, an error flag is set in an error register to indicate the presence of noise in the signal portion. The error register is repeatedly polled in order to detect the setting of the error flag. In response to detecting the setting of the error flag, a command to eliminate the signal portion is issued.

Abstract: The present invention is directed to a wireless electrical control system for power tool and specifically to a wireless control device for a router. The electrical control system may include a handle suitable for manipulating a router. A switch and a wireless transmitter are disposed in the handle. Communicatively coupled to the transmitter is a wireless receiver capable of receiving the transmissions from the transmitter in the handle. In alternative embodiments the wireless receiver is disposed in the router itself or the receiver is disposed in an outlet unit, which is capable of electrically coupling to the router's electrical cord and an electrical outlet. The wireless receiver of the present invention is capable of controlling the flow of electricity to the electrical system of the router so that the router is capable of being altered from the switch mounted on the handle, thus allowing users to change the power setting while retaining secure control of the router.

Abstract: A pneumatic compressor capable of supplying compressed gas to a pneumatic tool. The compressor can be powered alternatively by either a battery or an AC power source. The compressor comprises a permanent magnet DC electric motor and circuitry for converting the AC power source to DC power. The compressor includes a receptacle for accommodating one or more of a plurality of batteries and includes circuitry for using batteries having different voltages. The AC power source may also be used to charge a battery connected to the compressor.

Abstract: A cable driven actuator and actuator method involve a movable link that is movable about a path by a cable connected to the link, and a movable support member having a cable routing element. The support member is movable in a manner to change a moment arm of the cable acting on the link to control torque applied to the joint.

Abstract: A pelvic support unit is coupled to a base by a powered vertical force actuator mechanism. A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s). Wheel modules are independently powered to both rotate and steer, and, responsive to the control unit, are capable of rolling the exercise device in a direction of travel intended by the patient.

Abstract: A test circuit determines state of an electrical element supplied with alternating current and measures the duration of that state. The test circuit is connected to the element so that current flows to the test circuit when the element is in the state being measured. The test circuit rectifies the alternating current to periodic pulses, which are counted to determine the duration of the current and, thus, the state. The circuit is particularly useful for testing operation of a dishwasher pump motor that is interrupted periodically. The test circuit is connected to auxiliary contacts that open and close in correspondence with the operation of the pump motor.
