摘要:
Systems and methods of supporting communications over a common network connection in a master-slave field bus network with a first type of packet formatted with a time-sensitive protocol and a second type of packet formatted with a non-time-sensitive protocol are provided. The slave devices are configured with filters to prevent the first type of packet from reaching a configurator and the second type from reaching a master device. The slave devices are also configured with arbitration logic so that the packets formatted with the time-sensitive protocol are provided with a priority over the packets formatted with the non-time-sensitive protocol.

Systems and methods for providing Safe Torque Off signals using communication wires used for control signaling. Single channel Safe Torque Off signals can be provided as a DC voltage or AC voltage across two sets of twisted pair wires. Alternatively, two Safe Torque Off signals can be provided using both a DC voltage and an AC voltage across the two sets of twisted pair wires.

A decentralized motor drive arrangement provides high-voltage operational power and low-voltage standby power from a centralized distribution unit to remote motor drives using the same pair of interconnection power wires. The distribution unit includes a low-voltage power source which has one output terminal diode coupled to one of the output terminals of a high-voltage power source to form one output wire of the distribution unit. The other output terminals of the low-voltage and high-voltage power sources are directly coupled to form the other distribution unit outgoing power wire.

A trailer convertible between an in-use configuration and a storage configuration is provide with a fixed draw bar (4) extending to the full length of the trailer. A transverse cross-member (6) being pivotally connected to the drawbar (4). At least two foldable floor panel are mounted onto the drawbar (4). Each floor panel has a side panel fixed to its outside edge The floor panels are folded to an essentially vertical position and the transverse cross-member (6) rotated through about 90° to be aligned substantially parallel with the drawbar (4). A front and rear end panel are replaceably mounted onto the trailer. When converting the trailer from the in-use configuration to the storage configuration, the front and rear end panels are removed. The trailer being provided with wheel assemblies (20) pivotally mounted to the cross-member (6) and being rotatable through 90° when folding the trailer into the storage position.

A thermally enhanced memory module is claimed. The memory module includes a first extended electrical plane, and a thermal connection between a surface plane of its substrate and the first extended electrical plane. A first thermal management, such as a heat spreader, is coupled to the surface plane of the substrate and to the thermal connection.

This invention provides an apparatus and method for administration of animal venting therapy in which relieves excess bodily gases (Barotraumas) from the body cavity. The apparatus includes a spring loaded device for making the puncture; this in turn acts as a safety sheath when not in use. A non slip surface is on the front of the device. A main locking device is incorporated for additional safety when the unit is not in use. A soft touch cover for users comfort and with the use of a waist lanyard is additional items added for safety.
摘要:
A motion control system and method that includes a central controller configured to generate first and second demand control signals to be used to define actuation motion of respective first and second actuators. The central controller is in communication with first and second nodes by way of a data network, each node including at least a respective actuator configured to implement at an actuator time a motion or force-related effort based upon the respective demand control signal. Each node also includes a memory configured to store at least one respective propagation delay parameter related to a signal propagation delay between the central controller and the node. A timing mechanism establishes timing at each node based on the respective propagation delay parameter so that the actuator time at the nodes occurs simultaneously. Strictly cyclic and/or full-duplex high-speed communication can be supported. The network can be wired in a ring or as a tree and with twisted pair cabling or fiber. The central controller issues demand signals to the nodes that are actuator, servo motor drive, and/or I/O devices. The central controller can also provide a timing message that is used by the nodes, in conjunction with local delay correction circuitry, so that the simultaneous acquisition of data and the simultaneous implementation of controlled action occur.
摘要:
A method and system for managing memory modules or memory devices is disclosed. The memory modules or memory devices are managed by using a microcontroller on the memory module. A user can remotely control the memory module by sending instructions and data to the microcontroller. The microcontroller can cause the measurement of a number of operational parameters of the memory module. The values of the measured operational parameters can be displayed on a display unit that is attached to the memory module or displayed on a screen associated with the host system.
