摘要:
A shunt pulsation trap for a positive-displacement gas-transfer machine having a gas transfer chamber with an intake port and a discharge port and having at least one positive-displacement drive device (such as two cooperating rotors) defining a compression region of the transfer chamber. The trap includes a pulsation-trap chamber arranged for parallel fluid flow with the machine transfer chamber. The trap has a first (e.g., inlet) port in communication with the compression region of the transfer chamber (e.g., at least one lobe span away or totally isolated from the transfer-chamber intake port), a second (e.g., discharge) port in communication with the discharge port of the transfer chamber, and at least one pulsation dampener in the pulsation-trap chamber. In this way, the shunt pulsation trap traps and attenuates gas pulsations before discharge from the machinery transfer chamber, thereby reducing induced NVH and improving machinery efficiency.

An orthotic device includes a resilient portion configured to apply a force in one or more predetermined directions to assist or restrict movement of a part of a wearer's body, and a rigid portion configured to restrict movement of the body part. The rigid portion is removably-couplable to the resilient portion so that it can be removed from, and coupled to, the resilient portion while the device is being worn.

A touch sensor controller system for use in a vehicle of the type utilizing a software application to be interfaced with by an operator of the vehicle includes a touch sensor and a touch detector associated with the touch sensor. A touch gesture processor is provided which prevents unwanted or unintended touch gestures from being communicated to the application software during certain operating conditions of the vehicle. The touch gesture processor receives inputs of the operating conditions of the vehicle and receives touch gesture information from the touch detector, and the touch gesture processor is operative to determine the types of touch gestures to be permitted to be passed to the software application.

A board is provided that includes a pattern to facilitate attachment of the board to a frame structure. The pattern comprises a first array of marks disposed along a first imaginary line; a second array of marks disposed along a second imaginary line, said first and second imaginary lines being spaced a first predetermined distance apart; and a third array of marks disposed along a third imaginary line, said first and third imaginary lines being spaced a second predetermined distance apart. The board may be used in a variety of construction applications, where the pattern facilitates the quick attachment of the board to an underlying frame.

A message is divided into multiple message segments, and a network interface is selected from among a plurality of different types of network interfaces included within a communication device for transmitting each message segment. Each network interface is dedicated to a different type of communication protocol using a different encryption technique, and a network interface is selected for transmitting each message segment according to a pattern of the network interfaces. Secure transmission of the multiple message segments is initiated via the network interfaces according to the pattern.

Growing rod systems and methods for correcting spinal deformities include at least one growing rod assembly and at least one fluid delivery assembly. Each growing rod assembly includes a fluid actuator that is operable to extend first and second rod segments in opposite directions along the spine. The fluid actuator can be provided by, for example, a piston-cylinder actuator. Each fluid delivery assembly includes a fluid pump operably connectable to a fluid line, which in turn is connected to the fluid actuator. In one embodiment, the fluid actuator is of a linear design. In another embodiment, two linear or curvilinear fluid actuators are provided back-to-back and connected by a connecting rod that mounts to the mid-spine and is contourable. In another embodiment, the fluid actuator is of a curvilinear design to generally conform the normal spine. And in another embodiment, the fluid actuator includes a fluid-over-fluid shock absorber.

A battery-powered fueling data collection unit for use with a meter and a register associated with a fuel transfer apparatus and for use with a system for managing fueling transactions of a fleet operator using fuel transfer apparatuses at multiple locations includes a fueling data interface module for receiving fueling information from the fueling meter and/or register and an internal battery power source. A processor is provided for monitoring the power level in the battery and for detecting if the power level in the battery drops below a threshold amount. Also, a communications module is provided for wirelessly forwarding an alert to a remote computer to alert the remote computer that the battery power is low.

Described herein are methods for effectively and accurately measuring a patient response upon administration of one or more drugs to the patient. The methods are more sensitive than current methodologies. Also described herein are compositions comprising an analgesic and a sufficient amount of an antihistamine to enhance the analgesic properties of the analgesic. With respect to these compositions, the methods described herein are useful for evaluating qualities of pain, definite improvement, and one or more bodily functions of a subject afflicted with pain. The compositions described herein are useful in improving the quality of pain in a subject or a bodily function of a subject afflicted with pain or definite improvement of a subject afflicted with pain.
